DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a urinal for women having an elongated inlet member to be inserted between the labia majora of the women.
BACKGROUND ART
Portable urinals in various embodiments have been known for some time, and have mainly been developed for women suffering from urinary incontinence. A second type of urinal is for occasional use only, eg. for bedridden patients or immobilized non-incontinent women.
EP patent application no. 23 942, U.S. Pat. No. 4,495,355 and PCT publication no. 90/08561 disclose urinals to be used by women suffering from incontinence comprising an inlet member, a tubular section and a container. The inlet member comprises a small, oval, cup-shaped or gourd-shaped unit to be inserted between the labia majora of the wearer so that the unit will be completely surrounded by the labia majora. The unit is provided with a shallow recess or opening facing the female urethra. Opposite this opening the unit is provided with an outlet leading to a container. When a woman urinates, the urine rum first into the recess, through the tube and then into the collecting member. Since the recess is very small and the outlet tube is very narrow, urine easily collects in the recess. This causes overpressure in the recess so that urine flows over the edges rather than into the outlet tube into the collector. These incontinence devices are therefore suitable only for collecting small amounts of urine. If a woman intends to empty her bladder completely with the help of such a device, there is a considerable overflow risk. Devices of the above-mentioned type are also difficult to insert in the correct position.
A second type of urinals is described in FR patent application no. 2,624,004, EP patent application 314,578, GB patent application no. 2,126,902 and U.S. Pat. No. 4,528,703. These urinals are also provided with an inlet member and an outlet tube leading to a collecting container or the like. This second type of urinals differs from the first by the inlet member not completely surrounded by the labia majora when the urinal is correctly positioned. The urinals disclosed in the tint three patent specifications are thus provided with an inlet member having an outer portion for surrounding the labia majora and an internal projecting portion for surrounding the female urethral orifice between the labia majora. The urinal disclosed in U.S. Pat. No. 4,528,703 has a cup-shaped receiving member to be inserted between the female labia majora, the front part of said cup-shaped member narrowing to form a comparatively rigid tubular section which may be connected to a container. This type of urinal is primarily intended to be used by women suffering from incontinence who cannot easily collect large mounts of urine at a time. Several of the urinals mentioned above, especially the last one, are practically unusable when the woman is lying on her back.
In order to facilitate the positioning the two types of urinals described above, the inner part of the inlet member may be provided with a projecting part to be inserted into the vagina. This often causes discomfort to the wearer and may easily result in urine running into the vagina, which is unacceptable for hygienic reasons. In order to find the correct position for the urinal, a woman has to use both hands. That is why immobilized women often have to ask for help from another person for inserting the urinal. Inserting the types of urinals described above requires a woman to part her legs at a relatively wide angle. Then the woman, or a helper, has to part the labia majora with one hand and positioned the inlet member of the urinal with the other hand so that it covers the urethral orifice. It is frequently necessary to confirm the correct position of the inlet member around the urethra by means of a finger.
U.S. Pat. No. 3,963,020 discloses a non-portable urinal to be used by bedridden or immobilized women. This urinal comprises an inlet member and a collecting member. The inlet member is the upper portion of the collecting member com
