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 to solve the problem In order to restore the negative pressure inside the urination device to atmospheric pressure after urination, the problem was solved by integrally forming a valve part for sucking air into the urine receiving part 2. .

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 valve part 3 is provided in a urine receiving part 2 which is made slightly thicker on the inside thereof and has self-retaining properties.

The valve part 3 consists of an air suction valve 5, an air suction pipe 6, and an air suction hole 7, and is formed to protrude inward into a valve protection chamber 4 which is formed by bulging outward in the urine receiving part 2. There is.

The valve portion 3 is integrally formed with the valve portion protection chamber 4, the urine receiving portion 2, and other portions.
The thickness of the air intake tube 6 is doubled compared with the thickness of the urine receiving part 2 in order to provide sufficient self-retaining ability.

The valve protection chamber 4 surrounds the air suction valve 5 and the air suction pipe 6 of the valve portion 3, which operate under very delicate pressure, to protect them from contact with foreign objects, and to prevent air suction by deforming the urine receiving portion 2. It has a function of preventing the valve 5 from being opened.

With the above configuration, when the pressure inside the urine receiving section 2 becomes negative, the air intake valve 5 opens (see Fig. 2), and air pressure flows into the urine receiving section 2 from the air intake hole 7 and becomes atmospheric pressure. At the same time, the air suction valve 5 returns to its original state and closes due to its self-retention force. (See Figure 3) Γ Example It is made of medical silicone rubber that has an approximately elliptical shape in the longitudinal direction and has sufficient elasticity to accommodate body movements and body shapes, and a medical adhesive 8 is applied to the top surface. A sticking part 1 having a thickness of about 1 mm is provided, and a thick convex strip 9 having a width of 2 to 3 mm and a height of 3 mm is provided inside the sticking part 1.

Further, on the inner lower surface of the convex stripe 9, 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 about 1 mm.

A valve protection chamber 4 with an outer diameter of about 9 mm, a thickness of 1.5 mm, and a height of 6 mm is provided in the central front part of the urine receiving part 2, and the valve part 3 is formed in the protection chamber 4. do.

The valve part 3 consists of an air suction pipe 6 with a thickness of 1.5 mm and a diameter of 4 mm, and an air suction valve 5 with a thickness of about 1 mm.

A urination section 10 is provided at the rear of the urine receiving section 2, and the urination section 10 has a wall thickness of approximately 2 mm and has self-shape retention properties in order to smoothly drain the urine collected in the urine receiving section 2.
The funnel shape gradually narrows toward the tip, and at its base there is a roughly spherical hollow part 12 with a diameter about twice that of the tube-like connection part 11, and at the tip end there is a discharge tube 13.
Approx. wall thickness with self-retaining properties to connect with
It is a 1.5mm tube-shaped connection part 11.

To use, first shave the patient's pubic hair, clean the area from around the labia majora to the anus area, and then adjust so that a of the patch 1 is near the lower end of the mons pubis and 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 Effects of the invention The present invention has a simple structure, so it is easy to integrally mold it, and by providing the valve part 3, it is possible to prevent the unpleasant feeling caused by urine retention and to prevent urine leakage.

Furthermore, since the valve protection chamber 4 is formed, the valve part 3 can be protected from contact with foreign substances and deformation, and a safer and more reliable female urination device with a valve can be provided.
