Description

[Detailed description of the invention] Γ Field of industrial application The present invention relates to a female urinary device for physically disabled people, bedridden elderly people, and sick people who have difficulty getting up.

Γ Conventional Technology US Pat. No. 4,233,978 is a type that is attached to the female body part.

Γ Problems that the invention aims to solve Conventional female urination devices are attached to the relevant part of the woman and then connected to a urine bag, creating a sealed state, and when urine flows, the pressure is reduced and the pressure exceeds the self-retention ability. transform.

If the deformation occurs, the next time you urinate, urine may stay inside the urinary device or the discharge tube, or may not flow smoothly, causing discomfort and urine leakage.

Γ Means for solving the problem In order to restore the negative pressure inside the urination device to atmospheric pressure after urination, the problem was solved by attaching a porous membrane to the urine receiving part 2 for sucking air.

Γ Effect The female urinary device according to the present invention has an approximately oval shape in the longitudinal direction so as to cover the area from the lower end of the mons pubis to the outer periphery of the labia majora to the front of the anus, and has an attachment part made of extremely flexible rubber or plastic. A porous membrane storage chamber 3 is provided in a urine receiving part 1 and a urine receiving part 2 which is made slightly thicker on the inside thereof to have self-retaining properties.

A through hole 4 is formed at the center top of the porous membrane storage chamber 3, and a porous membrane 6 is attached along the inner edge portion 5 of the through hole 4.

The porous membrane 6 is made of a film, preferably a laminate film or fabric, having pores with a pore diameter of 0.5 to 3 .mu.m in order to allow air to pass through but not urine to pass through.

The size of the pores 4 depends on the diameter of the pores in the porous membrane 6, but is preferably 3 to 10 mm in diameter.

In order to attach the porous membrane 6 along the edge portion 5 so as to cover the through hole 4 from the inside, there are methods such as adhesion or pressing with a pressure ring 7.

With the above-mentioned configuration, when the pressure inside the urine receiving portion 2 becomes negative, air flows into the urine receiving portion 2 through the porous membrane 6, and the pressure becomes atmospheric pressure, so that deformation due to the negative pressure can be eliminated.

Γ Example It is approximately 1 mm thick and has an approximately elliptical shape in the longitudinal direction and is made of medical silicone rubber with sufficient elasticity to accommodate body movements and body shapes, and has a medical adhesive 7 coated on the top surface. A pasting part 1 is provided, and the pasting part 1
A thick convex strip 8 with a width of 2 to 3 mm and a height of 3 mm is provided on the inside of the holder.

Further, on the inner lower surface of the convex stripe 8, there is a urine receiving part 2 which has the function of receiving urine, immediately collecting it, and discharging it to the urinary drainage part 10.
is continuously formed to a thickness of approximately 1 mm.

A porous membrane storage chamber 3 with an outer diameter of about 12 mm, a height of 4 mm, and a thickness of 1.5 mm is provided at the central front part of the urine receiving section 2, and the porous membrane storage chamber 3 has a diameter of about 5 mm at the central top of the protection chamber 3. A through hole 4 is formed.

Next, a diameter 8
A porous membrane 6 made of a laminate film of biaxially stretched polytetrafluoroethylene and polyester nonwoven fabric of mm is covered, and a pressure ring 9 having an outer diameter slightly larger than the inner diameter of the porous storage chamber 2 is covered on top of the porous membrane 6. membrane 6
Fix it tightly.

The crimp ring 9 is made of plastic or metal, and its inner diameter is the same as the diameter of the through hole 4.

A urinary drainage part 10 is provided behind the urine receiving part 2, and the urination part 10 has a funnel shape with a wall thickness of approximately 2 mm and has self-shape retaining properties in order to smoothly drain the urine collected in the urine receiving part 2. It gradually narrows toward the distal end, and a substantially spherical hollow part 12 with a diameter approximately twice that of the tube-shaped connecting part 11 is provided at the base, and the distal end is connected to the discharge tube 13 via a connector. It is a tubular connecting portion 11 with a wall thickness of about 2 mm and having good shape.

To use it, first shave the patient's pubic hair, clean the area from around the labia majora to the anus area, and then adjust so that the a of the patch 1 is near the lower end of the mons pubis and the b of the patch 1 is in front of the anus. Starting from a of the pasting part 1, it is pasted sequentially along the shape of the private part so as not to create gaps, wrinkles, etc.

After pasting, by connecting the tube-shaped connecting portion 11 and the discharge tube 13, excreted urine can be stored in the urine bag 14 or the like.

Γ Effect of the invention The present invention has a simple structure and is easy to mold, and by providing a porous membrane that allows air to pass through but does not allow urine to pass through, it is possible to prevent the discomfort caused by urine retention and urine leakage.

Furthermore, since the porous storage chamber 3 is formed, it is possible to protect the device from contact and deformation, thereby providing a safer and more reliable female urination tool that does not generate negative pressure.
