BACKGROUND OF THE INVENTION
This invention relates to apparatus for fastening a tube, for example a
catheter, to a patient's body.
Medical personnel have a problem in taping urethral, abdominal, and chest
drainage tubes to a patient's skin. If a tube is not taped to the skin, an
accidental yank is directly transmitted to the urethra or skin stitches
which causes patient discomfort. Rarely do medical personnel have the
skill to make a proper mesentery using ordinary hospital self adhesive
tape for holding a catheter or tube to the skin. When the personnel have
sufficient skill, such ordinary tape does not work well since it is too
pliable and pulls off the skin too easily.
In U.S. Pat. No. 3,826,254 there is disclosed a needle or catheter
retaining appliance that includes a pad having a first section with a self
adhesive layer for adhering to a patient's body and a second section
adapted to be folded over the first section to hold a tube therebetween,
the adjacent surfaces of the first and second sections each having a self
adhesive layer.
U.S. Pat. No. 3,834,380 discloses a strip of tape having pressure sensitive
adhesive and a slit clamping tube molded integral with the tape on the
side opposite the adhesive. Latching means may be provided to retain items
on the clamping tube. The latching means includes a latching flap
adhesively secured to one side of the clamping tube to be folded thereover
and having a pad to interlock with a pad attached to the tape.
U.S. Pat. Nos. 3,696,920 and 3,630,195 disclose grooved blocks for holding
tubing, a layer of adhesive being provided for retaining the block on a
patient.
In U.S. Pat. No. 4,165,748 there is disclosed a catheter tube holder made
of a single piece having one side covered with a pressure sensitive
adhesive and has a central bridge portion adapted to be wrapped around the
tube with a nonadhesive surface abutting against the tube. Snaps or
adhesive spots are provided to hold the bridge portion folded as shown in
FIG. 2 of the patent, but permit separation of the spots so that the tube
can be removed without removing the end portions of the holder from the
patient's body.
SUMMARY OF THE INVENTION
Mesentery tube holder apparatus that includes a base plate of moderately
pliable material that will contour to a patient's skin, a self adhesive
coating on one surface of the base plate and at least one flap having one
end portion permanently adhered to the opposite surface of the base plate
and an opposite end portion having self adhesive thereon for adhering to
the tube.
One of the objects of this invention is to provide new and novel means for
holding a tube or catheter to a patient's skin. Another object of this
invention is to provide new and novel means for adhering to a patient's
body and holding a tube while permitting replacement of the tube without
removal of the device from the skin. A further object of the invention is
to provide new and novel means adherable to a patient's skin for holding
and supporting a tube while permitting limited movement of the held part
of the tube.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a plan view of the first embodiment of the invention in a flat
condition holding a tube, said view being generally taken along the line
and in the direction of the arrows 1--1 of FIG. 2;
FIG. 2 is a longitudinal cross sectional view generally taken along the
line and in the direction of the arrows 2--2 of FIG. 1;
FIG. 3 is a plan view of the second embodiment of the invention in a flat
condition holding a tube, said view being generally taken along the line
and in the direction of the arrows 3--3 of FIG. 4; and
FIG. 4 is a longitudinal cross sectional view generally taken along the
line and in the direction of the arrows 4--4 of FIG. 3.
Referring now to FIGS. 1 and 2, the first embodiment of the invention
includes a generally rectangular, longitudinally elongated base plate 10,
12 that includes a lower portion 10 made of a moderately pliable material,
for example plastic, that can be readily contoured to the skin of a
patient's leg, abdomen, chest or etc. but of sufficient bulk and rigidity
to prevent being dislodged by muscle flexing the skin surface or by
accidental pulling. Thus, the base plate lower portion is of greater bulk
and rigidity than the tape of bandages such as sold under the trademark
Band Aids.
In a flat condition the undersurface 10a of the base plate 10 is generally
planar while the upper surface of portion 10 is generally planar and
includes one end surface portion 10b, an intermediate surface portion 10d
and an opposite end surface portion 10f which has a depression 11 that
provides a thumb placement area. The undersurface 10a is covered with a
layer 14 of pressure sensitive adhesive (self adhesive) suitable for
adhering to a patient's skin.
The base plate upper portion 12 is preferably made of a soft, more pliable
material than upper portion 10, so as to more readily contour to a tube
20. In a base plate flat condition, the upper portion has a lower surface
permanently bonded to the surface portion 10d. From the end adjacent end
portion 10b the upper portion 12 has an upper surface that is curved
upwardly along 12b, thence downwardly and next upwardly to form a
transverse groove 12c and thence curved downwardly along surface portion
12d to terminate adjacent end portion 10f. Thus, the thickness of the base
plate at the uppermost parts of surface portions 12b, 12b is substantially
greater than at the most recessed portion of groove 12c. Even though the
upper portion is shown in FIG. 1 as being the same transverse width as the
lower portion, it is to be understood the upper portion may be of the same
transverse dimension as the intermediate portion 15b of flap 15 which will
be referred to hereinafter. Preferably the groove would extend across the
entire transverse width part of the upper portion even though the lower
portion is of a greater transverse width than the upper portion 12. In any
event, the groove would be of at least a transverse width to underlay the
width of flap portion 15b when in a position for holding a tube.
Even though it is preferred that upper portion 12 be made of a softer
material than lower portion 10, it is to be understood that portion 12 may
be made of the same material as that of portion 10 and portions 10, 12 may
be made from a single piece of material (integrally formed). Thus the base
plate whether formed of two different types of material or an integrally
formed member, has upper surface portions 10b, 12b, 12c, 12d, 10f.
There is provided a longitudinally elongated rectangular flap 15 that is of
a substantially smaller length and transverse width than the corresponding
dimensions of the base plate lower portion. The end portion 15a of the
flap that overlaps surface portion 10b is permanently secured to base
plate by a layer of permanent adhesive 16 (the thickness of the layers of
adhesive being exaggerated in the drawing). Flap 15 has a longitudinally
intermediate portion 15b that in a position of use overlays base plate
portions 12b, 12c, 12d and the adjacent part of the base plate portion
10f, the portion 15b having a layer of pressure sensitive adhesive 17
covering its surface that is adjacent the base plate and the base plate
upper surface having a layer 18 of pressure sensitive adhesive covering
the base plate upper surface that underlays portion 15b. Thus layer 18 is
substantially the same transverse width as that of the flap and extends
longitudinally along surface base plate surface portions 12b, 12c, 12d and
part of surface portion 10f. The flap has a tab end portion 15c opposite
end portion 15a that has no adhesive thereon so as to provide a finger
grip portion, there being no adhesive on the upper surface of the base
plate beneath tab 15c when the flap is in its position of use. As may be
noted in FIG. 1, in a position of use the tab 15c is longitudinally spaced
from thumb placement area 11.
Preferably peel-off back strips (not shown) are provided to cover the
entire undersurface area of adhesive layer 14, and between adhesive layers
17 and 18, which are to be peeled off just before use of the first
embodiment.
After the end portion of tube 20 has been properly extended into a body
opening (natural or surgically made) or a needle (not shown) on said end
portion of the tube extends through a skin puncture, the peel-off strip,
if any, covering adhesive 14 is removed and the first embodiment is
properly positioned between the part of tube to be held and the patient's
skin. Now tab 15c is lifted so that flap portion 15b hinges adjacent the
juncture of flap portions 15a, 15b and the tube pressed downwardly to
extend into the grooved portion of the base plate and be adhered thereto
by the adjacent part of adhesive layer 18 that extends longitudinally
across the groove surface portion. Then, with tab 15c under slight
tension, the tab is moved toward base plate surface portion 10f and a
finger or fingers moved along flap portion 15b so that the adjacent parts
of the adhesive layers between surface portion 12b and flap portion 15b
adhere to one another, the portion of layer 17 adheres to the adjacent
part of the tube 20 opposite layer 18 and the adjacent parts of layers 17,
18 between flap portion 15b and surface portions 12b, 12c, 12d and 10f
adhere to one another. Preferably the flap is made of a stretchy type of
tape so that it will more readily contour to the tube and the softer base
plate material 12.
The tube may be replaced without removal of the base plate from the
patient's skin. The thumb replacement area 11 on the base plate would
remind a person to hold down on the base plate while pulling up on tab 15c
to fold back portion 15b over portion 15a. Thereafter the tube may be
lifted up off adhesive layer 18, replacing with another tube, and tab 15c
moved to secure the tube to the base plate as previously described.
Referring now to FIGS. 3 and 4, the second embodiment of the invention
includes a longitudinally elongated generally rectangular base plate 30
made of the same material as plate 10, but in a flat condition has
generally planar upper and lower surfaces 30a and 30b respectively. The
lower surface is curved with a layer of pressure sensitive adhesive 36
that is adhered thereto.
A pair of generally rectangular flaps 31, 32 which advantageously may be of
the same size and shape, in a position the base plate is flat have
generally planar, remote end portions 31a, 32a respectively secured to the
base plate upper surface 30a by layers of permanent adhesive 33, and
adjacent upwardly extending intermediate portions 31b, 32b likewise joined
by the permanent adhesive 33. Intermediate portions 31b, 32b are
integrally joined to portions 31a, 32a respectively, and extend above
portions 31a, 32a, for example on 1/4" or higher, depending on the outer
diameter of tube the second embodiment is to be used with and the type of
usage. The intermediate portions 31c, 32c have one ends integrally joined
to portions 31b, 32b respectively to extend away therefrom and on their
adjacent surfaces there is provided a layer of pressure sensitive adhesive
35. The opposite end portions 31d, 32d are integrally joined to portions
31c, 32c respectively, do not have any adhesive thereon and serve as pull
tabs. Advantageously, a peel-off strip (not shown) may be provided to
cover the undersurface of adhesive layer 36 and a pull-off strip provided
between the adhesive layers 35 on flap portions 31c, 32c.
To use the second embodiment the peel-off strip, if any, is separated from
adhesive layer 36 and then the adhesive layer 36 adhered to the patient's
skin in the desired position. Now the tabs 31d, 32d are pulled apart, the
peel-off strip, if any, is separated from adhesive layers 35 and flap
portions 31c, 32c are molded around the tube 40 with finger pressure. Thus
the layer of adhesive 35 on flap portion 31c adheres to one side of the
tube and the adhesive layer 35 on flap portion 32c adheres to the opposite
side of the tube while the tube bottom is located closely adjacent the
juncture of portions 31c, 32c, to portions 31b, 32b. Portions 31c, 32c
that have adhesive 35 thereon are of sufficient lengths that the parts
adhesive layers 35 above the tube can be pressed together to adhere to one
another.
When it is desired to remove tube 40 the pull tabs can be pulled apart to
separate the layers of adhesive 35 above the tube and the tube removed
while adhesive 36 remains adhered to the patient's skin. Another tube can
be held in place by the flaps by following the procedure set forth above.
The flaps 31, 32 are made of flexible tape and due to the flexibility
thereof and of the adhesive used, portions 31b, 32b may be bent about
transverse axes parallel to the upper surface of the base plate and
twisted a limited amount about axes generally perpendicular thereof. The
length of portions 31b, 32b would in part depend on the usage. For
example, if the base plate 40 is to be adhered to the bridge of the nose
to hold a nasogastric tube, portions 31b, 32b advantageously would be of
substantially greater lengths (for example to reach down past the tip of
the nose so that flap portions 31c, 32c encircled the tube as it came out
of a nostril) then when, for example, being used affixed a tube to the
abdomen.
The base plates may be made in varying lengths and widths, the sizes and
shapes in part depending on the diameter of tube and in part on the part
of the body, for example thigh, abdomen or chest, that the tube is to be
affixed to.
