Description
This invention relates to improvements in urinary devices worn on
the body and, more particularly, to an improved female urinary
device.
The present invention is directed to a device of the type described
which is adapted to be worn on the body in a position to receive
urine flow when the wearer is sitting, standing or reclining. The
device is comprised of an assembly formed of a moldable, nontoxic
material and includes a tube having means at one end thereof for
mounting the same in fluid communication with a vaginal cavity. The
tube is adapted to be coupled at its opposite end to a fluid
receptacle and means is provided for holding the tube in place
while providing maximum comfort to the wearer. The nontoxic
material forming the assembly prevents harmful skin rashes and the
like which ordinarily result when toxic materials, such as latex,
contact the body. To this end, the assembly is formed of vinyl
material inasmuch as vinyl is nontoxic and is extremely stable and
has good storage properties at room temperature.
The assembly portion which contacts the tissues defining the
vaginal cavity is textured in a manner to provide maximum comfort
to the wearer. Moreover, the holding means is arranged to minimize
or substantially eliminate any seepage past the assembly, whereby
the area about the assembly is kept as sanitary as possible. The
assembly is further constructed to permit the user to move about
without irritation of body tissues and the reservoir configuration
of the tube is especially adapted for use when the wearer is
reclining. It is contemplated that the invention be disposed of
after a single use but, if desired, it can be washed and sterilized
and used again.
The primary object of this invention is to provide a female urinary
device adapted to be worn on the body for relatively long periods
of time while providing maximum comfort to the wearer and assuring
substantially complete and sanitary disposal of urinary wastes even
though the wearer is sitting, standing or reclining.
Another object of this invention is to provide a device of the type
described which can be held in place in an operative position by an
absorbent pad whereby the device is not only maintained in place to
receive urine flow at all times but it also cooperates with the pad
to permit the latter to absorb any seepage in and around the device
to thereby maintain the area as sanitary as possible during the
time when the device is in use.
Another object of this invention is to provide a device of the
aforesaid character whose configuration at one end is such as to
permit it to be partially inserted into and to conform generally to
a vaginal cavity to provide the desired comfort for the wearer, to
avoid irritation of sensitive body tissues, and to provide a seal
to minimize seepage.
Other objects of this invention will become apparent as the
following specification progresses, reference being had to the
accompanying drawing for an illustration of a preferred embodiment
of the invention.
In the drawing:
FIG. 1 is a side elevational view, partly in section, of the device
of the present invention;
FIG. 2 is an elevational view of the device looking from the left
in FIG. 1; and
FIG. 3 is an end elevational view of the device looking in the
downstream direction of the device.
The urinary device of this invention is broadly denoted by the
numeral 10 and includes a tube or tubular body 12 which is open at
both ends and has first portion and second portion 16 and 18
arranged in end-to-end relationship. Body 12 has a pair of opposed,
generally flat sides 20 (FIG. 2) which are interconnected by a
longitudinally straight end wall 22 and an irregularly-shaped end
wall 24 (FIG. 1) whereby sides 20 and end walls 22 and 24
effectively define portions 16 and 18.
End wall 24 has a first stretch 26 which is essentially parallel to
end wall 22, a second stretch 28 which is angularly disposed and
connected to stretch 26, and a third stretch 30 which is
essentially parallel to end wall 22 and stretch 26. The
configuration of end wall 24 therefore provides that portion 18 has
a maximum transverse dimension greater than that of portion 16,
whereby portion 18 defines a fluid reservoir broadly denoted by the
numeral 32 (FIG. 1). The relatively small cross section of portion
16 allows the same to be coupled to a conduit, such as a plastic
tube for connecting body 12 to a fluid receptacle.
A mounting member 34 is secured to the open end of portion 18 and
extends outwardly therefrom. Member 34 has an outer, tapered,
textured continuous surface 36 which is adapted to be inserted into
a vaginal cavity and to complimentally engage the outer portions of
such cavity tissues. Surface 36 has a velvet texture to provide
maximum comfort for the wearer to avoid irritation of the body
tissues. Also, the outer extremities of surface 36 are rounded, as
at the location denoted by numeral 38, to eliminate sharp corners
which may chafe the body tissues. The outer surface 36 essentially
conforms to the cavity-defining body tissues to provide an
effective seal against seepage to thereby maintain the area around
device 10 as sanitary as possible.
Body 12 and mounting member 34 are preferably of a one-piece
construction and, to this end, are formed from a moldable, nontoxic
material. Vinyl has been found to be especially suited for this
purpose since it is nontoxic, is stable and can be stored for long
periods of time without any substantial change in structural
characteristics. Using this material, device 10 can be molded and
the desired texture of surface 36 can be attained simultaneously
with the formation of the remainder of device 10. For this purpose,
the mold for device 10 in the vicinity of the area which defines
surface 36 is initially sandblasted so as to form tiny pits. During
the molding step, the pits form tiny projections on surface 36 to
provide the desired texture therefor.
Means is provided for holding the device in place with the mounting
member 34 at least partially inserted in a vaginal cavity. To this
end, member 34 has an outer, continuous shoulder 39 projecting
laterally from body 12. This shoulder cooperates with an absorbent
mounting pad 40, such as a sanitary pad, having a die-cut, central
opening 42 therethrough for receiving the end of portion 18 of body
12. Pad 40 abuts shoulder 39 in the manner shown in FIG. 2 and pad
40 is held in place on the body of the wearer in any suitable
manner, such as the usual way of keeping sanitary pads in place
during a menstrual cycle. In such use, the pad is urged against the
body and, when held in this manner, it also holds mounting member
34 in the vaginal cavity. The die cutting of opening 42 allows for
a tight fit of body 12 in the opening and the location of the
opening provides that the pad circumscribes member 34 as shown in
FIG. 3.
The absorbency of pad 40 serves to collect any seepage which may
happen to issue from the cavity to thereby maintain the area as
sanitary as possible. Both device 10 and pad 40 can be disposed of
as a unit after a single use, whereupon a new device and pad can be
inserted in place.
In use, device 10 is first inserted through opening 42 until pad 40
abuts shoulder 39 in the manner shown in FIG. 2. Mounting member 34
is then inserted into a vaginal cavity until pad 40 engages the
area immediately exteriorly of the cavity. The pad is then secured
in place in the usual manner to thereby hold device 10 in
fluid-receiving relationship to the cavity. Then, a conduit is
coupled to the outer end or portion 16 of body 12 whereby the body
can be connected to a fluid receptacle. Thus, any flow from the
vaginal cavity into reservoir 32 will be directed through body 12
and into the receptacle coupled thereto.
End wall 22 is made longitudinally straight so that it will
maintain receptacle 32 drained at all times. To this end, end wall
22 is adapted to define the rear extremity of the device when the
same is worn so that the wearer can recline without interrupting
the drainage from body 12 into the fluid receptacle.
When the assembly is to be changed, the old device and its pad are
thrown away and replaced by a new device and its pad.
Device 10 is formed from a nontoxic, thermoplastic material. Vinyl
is suitable for this purpose since it is extremely stable and has
good storage properties at room temperature.
Since device 10 can be easily and inexpensively molded, it can be
made to have a relatively low unit cost to permit it to be sold at
a relatively low retail price and thereby to be disposed of at
relatively frequent intervals at minimum expense. This low-price
feature allows the user to avoid infection and irritation due to
prolonged use. This is extremely important for paraplegics and
others who have no control over their urinary systems and must be
provided with a device of this type at all times.
Device 10 can be made by a dipping process or can be made by
injection molding techniques. If the molding step is carried out by
a dipping process, the curing preferably takes place from the
inside toward the outer surface of the device with the buildup of
the wall of the body 12 and member 34 being controlled by the way
in which the dipping occurs. The setting of the material is
preferably done by hot atmosphere oven curing and the texture of
surface 36 can be assured by the way in which the mold is made.
While one embodiment of this invention has been shown and
describes, it would appear that other adaptations and modifications
of this device can be made without departing from the true spirit
and scope of the invention.
