System for holding an indwelling catheter
Abstract
A system for holding an indwelling catheter above the heart of a
patient wearing one. When a patient has a central line placed, the
catheter is sutured into the patient's chest and the external
portion of the catheter, the portion that remains outside the
patient's body, must be carefully protected and kept sterile; and it
must also be carefully held above the level of the patient's heart
and the insertion point of the catheter so that the patient's blood
does not flow back into the catheter, potentially causing
life-threatening clotting or infection. A sterilizable, disposable
hanger, which is connectable to the port end (the external end) of
the catheter, can be suspended from a necklace or neck cord by
passing the neck cord through apertures in the hanger. This system
allows a patient to hang the catheter from a neck cord. Using the
hanger frees patients from using tape on their skin or pins in their
clothing to hold their catheter in place.

Description
BACKGROUND
People with medical conditions which require indwelling catheters
(usually venous), chronic or acute, for the delivery of drugs find
that these catheters are uncomfortable and difficult to maintain.
Indwelling catheters allow medical professionals to deliver
intravenous medications continuously or repeatedly without
repeatedly puncturing a vein. For example, cancer patients who
require continuous infusions of chemotherapeutic agents receive
their medications through indwelling catheters. For the medical
professional, these indwelling catheters are a necessary
convenience. For the patient, these catheters are uncomfortable,
difficult to keep clean and sterile, and easy to pull out. They also
represent a significant risk of life-threatening systemic infection.
Chronic indwelling catheters are surgically inserted into a vein
through the patient's chest wall and are sutured to the patient's
skin to prevent the insertion end from slipping out. These catheters
can be in place for months or even years at a time. Typically, the
external port end of the catheter is looped and secured to the skin
with tape or is pinned to the patient's shirt, undergarment or bra.
Movement and exercise are made difficult and uncomfortable if the
clothing that the catheter is pinned to moves in relation to the
insertion point of the catheter. Sometimes, the catheter is
accidentally pulled out because the patient forgets to detach it
from their clothing when undressing. Such problems occur even in
acute such catheter use for a brief time.
Patients find that sleeping is especially uncomfortable with one of
these catheters in place. These catheters are often pulled out
during sleep. For example, if the catheter is pinned to a garment
and the garment is not carefully adjusted when the patient rolls
over during sleep, the catheter can easily be pulled out. Patients
have difficulty sleeping because of worry over losing their
catheters, soiling the bed sheets with blood, and risking infection.
Patients who secure their catheters with tape may develop rashes or
allergic reactions to the adhesive from the tape. Hirsute patients
may be forced to either shave their chests or experience the pain of
taped hair. Tape with less adhesive may lose its strength in hot
weather when the patient perspires. Strongly adhesive surgical tape
is uncomfortable to remove for daily treatments, especially after
months of using tape in the same location.
The insertion point of these catheters is often the site of
infection. Infection at the site of an indwelling catheter can
follow the catheter directly into the bloodstream, creating
life-threatening systemic infection. To prevent this serious
infection, patients are charged with the responsibility of keeping
the insertion point clean and sterile. The catheter itself must also
be kept clean and the patient is often required to flush the
catheter with saline. To further complicate the maintenance of these
catheters, if the port end of the catheter falls below the insertion
site or the level of the patient's heart, venous backflow or siphon
effect can occur. This backflow seriously increases the risk of
infection and clotting.
Often, whether these catheters are taped to the patient's chest or
pinned to clothing, they are visible through shirts and clothing
worn by the patient. The catheters are especially visible when taped
to the most prominent area of the patient's pectoral muscle or
pinned to the undergarment, shirt or bra. Patients find these
catheters to be unsightly and embarrassing, a visible reminder of
their illness.
OBJECTS
It is an object and feature of this invention, preferred forms of
which are described in detail hereinafter, to overcome these
disadvantages and drawbacks and to provide significant improvements
in the care and maintenance of indwelling catheters not previously
available.
It is an object and feature of this holding system to allow the
external port end of the catheter to be suspended from the patient's
neck. This holding system allows patients to wear their catheters
like jewelry. Using this holding system, patients can wear their
catheters discretely so that they hang midline on the chest, like
jewelry, instead of being pinned prominently on the patient's
undergarment, shirt or bra or taped prominently on the patient's
pectoral muscle.
It is an object and feature of this invention to keep the port end
from dropping below the level of the insertion end and the level of
the patient's heart, and therefore reduce the risk of infection and
clot-causing backflow or siphon effect. It is an object and feature
of this invention to maintain the port end in a position carefully
maintained by the length of the suspending element. It is also an
object and feature of this invention to provide a sterile and
sterilizable contact point between the catheter and holding system
to help the patient fight infection.
This holding system, in a preferred form, also provides a holding
system which does not require the use of uncomfortable, painful or
rash-causing tape. It is an object and feature of this invention, to
provide a holding system which allows patients to sleep without
worrying so much that changing sleeping positions might rip the
catheters from their chests. This holding system, in a preferred
form, provides a holding system which allows patients to disrobe
without worrying that changing clothes might rip the catheters from
their chests.
It is an object and feature of this invention to provide a holding
system which allows patients a greater range of motion. It is also
an object and feature of this invention to reduce the patient's
worry that exercise or movement will cause their catheter to be
pulled out. It is a further object and feature of this invention to
provide that advertising or decorative materials can be attached to
the holding system. For example, children can affix stickers or
other decorative materials to a preferred form of this holding
system.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS AND BEST MODES OF
PRACTICE
As FIG. 1. illustrates, a preferred embodiment of the holding system
30 (embodying herein a holder system for comfortably and flexibly
holding a port end of an indwelling catheter above a heart of a
patient) of the present invention may be worn by a patient 33. The
holding system 30 preferably includes suspender 31 and hanger 34
(embodying herein hanging means for being suspended by a neck cord).
Hanger 34 preferably includes aperture 50 (as illustrated in FIG. 4)
through which suspender 31 may be threaded, and catheter cap 51
(embodying herein catheter cap means for releasably holding the port
end of the indwelling catheter, and embodying herein hanging means
comprising such catheter cap means and connector means for
connecting with such neck cord, and also embodying herein a catheter
cap structured and arranged to releasably hold the port end of the
indwelling catheter, and even further embodying herein such hanger
comprising such catheter cap and at least one aperture structured
and arranged to hold the neck cord). Suspender 31 is preferably of
the type which goes around a neck 32 of a patient 33; and suspender
31 is preferably a neck cord, i.e., a flexible material of small and
relatively constant cross-section, although it may in certain cases
be suitable that necklaces, jeweled or not, even not of constant
cross-section, will be appropriate (embodying herein the neck cord).
Hanger 34 (embodying herein a hanger structured and arranged to be
suspended by a neck cord) is preferably attached slidingly to
suspender 31. As FIG. 1 also illustrates, preferably attached to
hanger 34 is port end 37 of catheter 38. Port end 37 normally
includes the actual catheter port plus universal needleless
connector 42 whose male end 44 connects to catheter cap 51 of hanger
34 (catheter 38 embodying herein such catheter comprising a port
end).
As illustrated in FIG. 1, suspender 31 is preferably of an
appropriate length to maintain port end 37 of catheter 38 above the
level of the patient's heart and above the level of the insertion
point (of the indwelling catheter) through the patient's chest
(suspender 31 embodying herein a suspender structured and arranged
to suspend such hanger above the heart of the patient). Because the
preferred length of suspender 31 is different for each patient,
depending on the patient's size, the length of suspender 31 is
preferably adjustable. When suspender 31 is a preferred length, the
risk of retrograde venous flow, backflow or siphon effect, is
reduced. Retrograde venous flow, backflow or siphon effect may cause
infection or clotting. Preferably, suspender 31 also maintains the
position of the port end 37 of catheter 38 midline on the chest
below the sternoclavicular junction, anterior to the manubrium, and
inferior to the jugular notch.
In FIG. 1, holding system 30 is shown hanging outside a shirt 36 for
the purposes of illustration. FIG. 1 shows catheter 38 disappearing
inside a shirt through hole 35. Alternately, holding system 30 is
worn so that it hangs underneath shirt 37, hidden from view.
FIG. 2 illustrates in enlarged front view the preferred embodiment
of FIG. 1. As FIG. 2 illustrates, suspender 31 (embodying herein
suspending means for suspending such hanging means above the heart
of the patient) preferably slidingly holds hanger 34, which is
connected to port end 37 of catheter 38, shown with a clamp 43 on
it. Universal needleless connector 42 is preferably a disposable
sterilizable connector with a male end 44 and a female end 45 such
as a Clave (R). [Clave (R) is a registered Trademark of ICU Medical,
San Clemente, Calif., is readily available from medical supply
sources and is well known in the art.]
Catheter 38 is preferably an indwelling catheter, typically a
chronic tunneled central venous catheter with a male-ended adaptor
46 such as a Hickman (R), Broviac (R), Leonard(R) or Groshong (R).
[Hickman (R), Broviac (R), Leonard(R) and Groshong(R) are Trademarks
of C.R. Bard, Inc., Murray Hill, N.J., 07974, are readily available
from medical supply sources and are well known in the art.)]
Catheter 38, even without a universal needleless connector 42,
typically has a male-ended port end 44a (see FIG. 2) of adaptor 46
which will properly connect directly to the interior threads of the
catheter cap 51 (see FIG. 2) of the holder system of the present
invention.
FIG. 3 is a partial cross-sectional view of the preferred embodiment
as shown in FIG. 2. FIG. 3 illustrates hanger 34 in cross-section.
Hanger 34 has a top end 39 and a bottom end 40. Top end 39 of hanger
34 preferably includes an aperture 50 through which suspender 31 is
shown passing (for connecting hanger 34 with suspender 31). Aperture
50 is preferably sealed-off (as illustrated) from catheter cap 51 by
a sealed divider 54 (embodying herein that such hanging means
further comprises a divider means, between such aperture means and
such catheter cap means, for assisting maintaining the sterility of
the port end of the indwelling catheter; and also embodying herein
that such hanger further comprises a divider between such aperture
and such catheter cap structured and arranged to assist maintaining
sterility of the port end of the indwelling catheter), preferably
dome-shaped, (embodying herein that such divider comprises a dome)
so that catheter cap 51 can maintain a sterile environment,
separated from the non-sterile suspender 31. As FIG. 3 also
illustrates, aperture 50 preferably includes a curve 52 to
facilitate sliding movement of hanger 34 along suspender 31. The
bottom end 40 of hanger 34 also preferably includes catheter cap 51.
Catheter cap 51 is preferably interiorly threaded (see FIG. 2) to
receive the port end 37 of a catheter (with or without a universal
needleless connector).
FIG. 3 also illustrates that catheter cap 51 may preferably include
a very small hole 53 to allow air to escape when threaded male end
44 of universal needleless connector 42 is threaded securely into
female-end threaded catheter cap 51. This very small hole 53
(embodying herein that such divider comprises a small hole
structured and arranged to assist in preventing back air pressure on
the catheter) may reduce the risk of infection and clotting by
allowing air to escape and reducing air pressure against universal
needleless connector 42 and catheter 38 when the two ends are
screwed together.
FIG. 4 is a side view of holding system 34 (of the embodiment of
FIG. 1) illustrating aperture 50 through which the suspender
threads. Aperture 50 is preferably large enough to accommodate
suspender 31 without constricting suspender 31 or restricting the
sliding movement of hanger 34 (embodying herein that such aperture
comprises a sliding connection with the neck cord) in any way. FIG.
4 also illustrates preferred curve 52 in side-view.
FIG. 5 is a bottom view of hanger 34 illustrating a preferred
embodiment of female-end threaded catheter cap 51. The internal
features 47 of this region are preferably constant through all of
the different embodiments of FIGS. 1-16 because, in each of these
embodiments, it must accommodate a standard male end 44 of universal
needleless connector 42 (or the similar port end 44a of the
indwelling catheter adaptor). However, the external shape 48 of
catheter cap 51 may be changed for decorative or practical purposes.
For example, it may be preferable for the external shape 48 of
catheter cap 51 to be more flattened or oval than round so that
hanger 34 will lay flatter with less rotation against a patient's
chest.
FIG. 6 is a perspective view illustrating another preferred
embodiment 55 of hanger 34 of the present invention. Embodiment 55,
illustrated in FIG. 6, preferably includes a female-end threaded
catheter cap 51 which can receive a male-end threaded universal
needleless connector 42 described above (or port end of the catheter
without the connector 42, as stated previously), and aperture 56.
Aperture 56 preferably has a different shape compared with that
described in FIGS. 3 and 4, but which serves the same purpose.
Aperture 56 is preferably large enough to accommodate suspender 31
(as illustrated in FIG. 3) without constricting suspender 31 or
restricting the sliding movement of embodiment 55 along suspender 31
in any way. FIG. 6 also illustrates a slight curve 57 (externally
concave and internally convex) in aperture 56 to facilitate sliding
movement along suspender 31. In another preferred embodiment,
aperture 56 may be smaller for the purpose of limiting sliding
movement of hanger 34 along suspender 31. It might be preferable to
restrict sliding movement to decrease the risk of the catheter
kinking or otherwise becoming entangled.
FIG. 7 is another perspective view illustrating another preferred
embodiment 60 of hanger 34. Embodiment 60 preferably includes a
female-end threaded catheter cap 51 which can receive male-end
threaded universal needleless connector 42 described above, and ring
61 (another form of aperture 50 and the other aperture forms herein
illustrated). Suspender 31 (as illustrated in FIG. 3) can be
threaded through ring 61. Ring 61 is also preferably shaped to allow
embodiment 60 of hanger 34 to move slidingly along suspender 31
without constricting suspender 31 or restricting the sliding
movement of embodiment 60 along suspender 31 in any way.
FIG. 8 is another perspective view illustrating another preferred
embodiment 64 of hanger 34. Embodiment 64 preferably includes a
female-end threaded catheter cap 51 attached to a two-aperture
suspender holder 65 (embodying herein at least two apertures). The
two-aperture holder 65 preferably includes two apertures 66 through
which suspender 31 can be threaded. Suspender holder 65 is also
preferably shaped to allow embodiment 64 of hanger 34 of the present
invention to move slidingly along suspender 31 without constricting
suspender 31 or restricting the sliding movement of embodiment 64
along suspender 31 in any way.
FIG. 9 is another perspective view illustrating another preferred
embodiment 67 of hanger 34 of the present invention. As FIG. 9
illustrates, tunnel-type aperture 68 preferably includes a curve 69
(embodying herein an internally convex curve structured and arranged
to assist such aperture to move slidingly along the neck cord) for
assisting embodiment 67 to move slidingly along suspender 31 (as
also shown in FIG. 3). As FIG. 9 also illustrates, a hook 70 is
preferably attached to the outside of embodiment 67. Hook 70
preferably allows for the attachment of a surface 75 (as shown in
FIG. 13) for attaching advertising material, decorative stickers 76
or other indicia 77 on visible portion of preferred embodiment 67 of
the present invention. The back side of surface 75 preferably
contains a clip (not shown) which can slide through hook 70 to
removably attach in a well-known manner a surface 75 to preferred
embodiment 67.
FIGS. 10 and 11 illustrate another preferred embodiment 79 of hanger
34. In FIGS. 10 and 11, the aperture element 81 is tunnel-shaped
(embodying herein a tunnel shape). FIGS. 10 and 11 illustrate a
preferred rotatable attachment 80 (or swivel) between catheter cap
51 and aperture 81. FIG. 11 is a cut-away side view of embodiment 79
through the section 11--11 of FIG. 10. As shown in FIG. 11, aperture
element 81 is preferably manufactured as a separate piece from
catheter cap 51 of hanger 34. Bottom end 84 of aperture element 81
is preferably conical in shape, with bottom end 84 being smaller in
cross-sectional diameter than top end 86, with groove 82 being
preferably situated between bottom end 84 and top end 86. Annular
flange 83 of catheter cap 51 is preferably flexible enough to flex
outward so that the two pieces, aperture element 81 and catheter cap
51 can preferably be attached together by pushing bottom end 84 of
aperture element 81, with its conical shape, down into catheter cap
51, so that annular flange 83 flexes outward just enough to
accommodate the slight increase in diameter of the conical bottom
end 84 of the aperture element 81 until annular flange 83 is seated
into groove 82 of catheter cap 51. Annular flange 83 at the top of
catheter cap 51 preferably fits rotatably into groove 82. When
attached together, with annular flange 83 seated into groove 82 of
catheter cap 51, aperture element 81 can preferably rotate
bidirectionally 360 degrees in relation to catheter cap 51
(embodying herein an anti-kinker to assist in preventing kinking in
the indwelling catheter; and also embodying herein that such anti-kinker
comprises a swivel connection between such catheter cap and such
aperture).
FIG. 12 illustrates another preferred embodiment 90 of hanger 34,
showing advertising or other decorative indicia 77 directly applied
to embodiment 90. Embodiment 90 preferably includes a female-end
threaded catheter cap 51 which can receive, e.g., the male-end
threaded 44 universal needleless connector 42 described above, and
aperture 91. Embodiment 90 also preferably includes aperture 91
(with a different shape compared with those described in previous
figures, but which serves the same purpose). Aperture 91 is also
preferably large enough in diameter to accommodate suspender 31 (as
illustrated in FIG. 3) without constricting suspender 31 or
restricting the sliding movement of embodiment 91 along suspender 31
in any way.
FIG. 13 is another perspective view illustrating another preferred
embodiment 94 of hanger 34. Embodiment 94 preferably includes a
female-end threaded catheter cap 51 which can receive the male-end
threaded 44 universal needleless connector 42 (See FIG. 3), and
aperture 95. Embodiment 94 preferably includes aperture 95 with a
different shape compared with that described in FIGS. 2-12, but
which serves the same purpose. Aperture 95 is preferably large
enough to accommodate suspender 31 (as illustrated in FIG. 3)
without constricting suspender 31 or restricting the sliding
movement of embodiment 94 along suspender 31 in any way.
FIG. 13, mentioned previously, also illustrates that advertising or
decorative stickers 76 containing indicia 77 (embodying herein
indicia), such as cartoon characters, may be applied to surface 75.
Surface 75 may be preferably clipped to hook 70 (as illustrated in
FIG. 9) embodying herein that such indicia is removably attached to
such hanger by hanging such indicia from such hook. Surface 75 is
preferably attached to hanger 34, as illustrated in embodiment 94,
by glueing, welding, or another suitable type of adhesive process.
Surface 75 may, in another embodiment, be manufactured to be
integral with hanger 34. For example, surface 75 may be manufactured
in the same mold as the rest of embodiment 94 when a plastic
embodiment is made. In other preferred embodiments, decorative
features such as bola ties or charms can be clipped to hook 70.
Advertising material may be in the form of embossed plastic or
metallic indicia. Decorative indicia are particularly appealing for
pediatric patients who may find their catheters to be embarrassing
and unwieldy. Physicians may choose to give stickers to their
pediatric patients when these patients visit for treatment. The
ability to decorate their catheters and change the decorations on
their catheters may increase compliance among pediatric patients.
FIG. 14 is a perspective view illustrating a preferred embodiment of
suspender system 97. In this preferred embodiment 97, suspender 93
is an eyeglass holder with plastic loop adapters 92; however
suspender 93 may be adapted to support/suspend a hanger of the
present invention by means of a rigid adapter 98, a preferably
cotton-swab-shaped stiff rod (embodying herein that such adapter
means comprises a rigid bar portion suitable to pass through such
aperture means). Adapter 98 allows a patient to use commonly
available eyeglass-holders to suspend their catheters 38 around
their necks 32 (See FIG. 1). FIG. 14 illustrates adapter 98 as it
would pass through a two-hole holder 64, shown in dotted lines (and
as illustrated in FIG. 8). Adapter 98 (embodying herein an adapter
structured and arranged to pass through such aperture) would
preferably slide through any of the aperture embodiments illustrated
in FIGS. 1-13. When suspender 31 has an plastic loop adapter 92 on
it, enlarged ends 99 will keep the eyeglass-holder adapter 92 from
sliding off the ends 99 of adapter 98.
FIG. 15 is a front view illustrating another preferred embodiment
101 of suspender system 96. Suspender system 96 includes eyeglass
holders with plastic tube adapters 105. Suspender system 96 attaches
to a modified-U-shaped rigid adapter 102 (embodying herein such
eye-glass holder adapter comprising a rigid bar portion) which
allows a patient to use the plastic tube adapters 100 type of
commonly available eyeglass holders to suspend their catheters 38
around their necks 32 (embodying herein an eye-glass holder adapter
constructed and arranged to fit through such at least one aperture).
In this preferred embodiment 101, U-shaped-rod adapter 102 suspends
hanger 34 in a predictable position. U-shaped rod adapter 102, by
limiting the sliding movement of hanger 34 along suspender system
96, may limit kinking in the catheter (embodying herein that such
anti-kinker is structured and arranged to limit movement of such
hanger with respect to the neck cord). Hanger 34 will be restricted
in its ability to slide along adapter 102 but will still be able to
rotate around U-shaped adapter 102. FIG. 15 also illustrates that a
suspender 31 may preferably have an adjustable element 103 for the
purpose of adjusting the length of suspender 31 in well-known ways.
FIG. 16 is a front view illustrating a preferred embodiment of the
present invention suspending on a suspender 31 more than one hanger
34 (embodying herein a second such hanging means, wherein each such
hanging means is suspended by the same such suspending means and
also embodying herein a second such hanger, wherein each such hanger
is suspended by the same such suspender), preferably up to three
hangers 34 since multiple-port indwelling catheters may at times
have two or three ports. FIG. 16 also illustrates that the catheter
cap of the present invention may be connected with either a male-end
threaded universal needleless connectors 42 (shown connected to one
hanger 34) or directly with the adaptor end 44a of the adaptor 46 of
the indwelling catheter (shown connected to the other hanger 34).
In a preferred embodiment, suspender 31 can be made of washable
and/or disposable material such as string, nylon or cotton cording,
decorative materials such as gold, silver or other metal chain, or
leather. These materials thread through any of the preferred
aperture features illustrated in FIGS. 1-16 and are adjustable by
altering the length of the materials. Suspender 31 can also
preferably be eyewear retainers or eyeglass-holders such as those
available from Croakies (.TM.), Fields Accessories (.TM.), Shockers
(.TM.), King Link (.TM.) eyeglass holders or Corinne McCormack, Inc.
(TM), used in association with an adapter such as U-shaped rod 102
(See FIG. 15) or rod 98 (see FIG. 14) or any other similar/suitable
adapter of the type illustrated of the present invention. Eyeglass
holders are commonly available and are normally adjustable (see FIG.
15).
FIG. 17 is a perspective view of another preferred embodiment of the
holder system of the present invention, utilizing a similar
suspender system to that of FIG. 14 but showing an alternate
embodiment of the hanger. Hanger 34a also includes a catheter cap 51
at its bottom end but does not include any apertures (as for other
hangers 34). Instead, hanger 34a utilizes adapter portions 98a,
similar in purpose to adapter 98 of FIG. 14 but being a unitary part
of hanger 34a rather than requiring apertures in hanger 34 for
support. Preferably, there will be included a suitable radius 110 to
provide additional strength to the juncture between adapter portions
98a and the main body portion of hanger 34a. Eyeglass holder 93 is
preferably connected with adapter portions 98a similarly as for the
suspender system of FIG. 14.
FIG. 18 is a perspective view illustrating another alternate
embodiment of the holder system of the present invention, utilizing
a similar suspender system to that of FIG. 15 but employing yet
another alternate embodiment of the hanger. Hanger 34b also includes
a catheter cap 51 at its bottom end but does not include any
apertures (as for other hangers 34). Instead, hanger 34b utilizes
adapter portions 102a, similar in purpose to adapter 102 of FIG. 15
but being a unitary part of hanger 34b rather than requiring
apertures in hanger 34 for support. Preferably, there will be
included a suitable strengthening portions 111 to provide additional
strength to the junctures between adapter portions 102a and the main
body portion of hanger 34b. Eyeglass holder 96 is preferably
connected with adapter portions 102a similarly as for the suspender
system of FIG. 15.
FIG. 19 is a perspective view of the hanger embodiment 34b of FIG.
18, illustrated without eyeglass holder 96 attached.
Any of the hanger embodiments illustrated in FIGS. 1-19, including
the hanger 34 and suspender elements 98 and 101 may preferably be
made of moldable or injectable, preferably disposable, plastic
(embodying herein essentially a disposable plastic material); and
for suitable purposes, may be made of metal, including gold, silver,
brass or other decorative metals (embodying herein jewelry-grade
metal). In a preferred embodiment, hanger 34 is sterilizable,
lightweight, inexpensive, easy to use, and can be sold in disposable
sterile packs.
