technical field

The invention relates to the technical field of medical devices, in particular to a manual pump-controlled urethral valve.

Background technique

Urinary incontinence is clinically defined as the loss of self-control of urination due to bladder and urethral sphincter damage or neurological dysfunction, which causes urine to flow out involuntarily. Urinary incontinence is a common and frequently-occurring disease that can occur at any age and gender, especially women and the elderly. Urinary incontinence can lead to complications such as perineal and sacrococcygeal dermatitis and pressure ulcers, which not only makes people uncomfortable, but also affects the patient's quality of life for a long time and seriously affects the patient's mental health.

There are many causes of urinary incontinence, among which functional defect or trauma of urethral sphincter is one of the main causes of urinary incontinence. For urinary incontinence caused by urethral sphincter dysfunction, conservative treatment and surgical treatment methods or measures such as nursing appliances, skin and psychological care are mainly adopted clinically. Conservative treatments such as medicine or traditional Chinese medicine are only suitable for patients with mild urinary incontinence, and are not effective for patients with moderate and severe urinary incontinence. Surgical treatment is easily limited by differences caused by various reasons such as age and gender of patients, and it is easy to cause complications such as dysuria, bladder perforation, and vascular injury, and the long-term efficacy is still unclear. Nursing measures can only alleviate the symptoms of urinary incontinence, but cannot solve the problem of urinary incontinence from the source of the disease.

The pump chamber and the lower housing chamber are not connected to each other, and there is no working medium 7 inside the pump chamber.

The pump body 2 can be in the shape of a cylinder with upper and lower ends connected, similar to a round tube; the pump body 2 is a non-elastic body; the upper end of the pump body 2 is a hand-pressed film 1, and the lower end is a pressure-bearing film 3; the hand-pressed film 1, the bearing The pressure film 3 and the pump body 2 form a closed structure; the inside of the pump body 2 is provided with a plunger 4, the upper end of the plunger 4 is connected to the hand pressure film 1, and the lower end of the plunger 4 is connected to the pressure-bearing film 3; and the plunger 4 can be formed by Made of non-metallic rigid material to ensure the strength of the plunger 4. The upper end of the plunger 4 can be fixedly connected with the hand-pressed membrane 1, and the lower end of the plunger 4 can be fixedly connected with the pressure-bearing membrane 3.

Both the hand-pressed membrane 1 and the pressure-bearing membrane 3 can be made of medical elastic materials, which have a certain deformation capacity, and the pump body 2 is a non-elastic body. The pump chamber and the lower accommodation chamber rely on the pump cover 6 and the plunger 4 to form a closed pump chamber and the lower accommodation chamber, and the working medium 7 is located in the lower accommodation chamber.

The lower accommodation chamber communicates with the valve body 9, so that the working medium 7 in the lower accommodation chamber flows into the valve body 9; Side; the position of the valve cover 11 relative to the urethra 12 remains unchanged, and the valve membrane 10 squeezes the urethra 12 under the action of the working medium 7, so that the urethra 12 is closed.

When the manual membrane 1 is not pressed, the working fluid 7 fills the lower chamber and the valve body 9, so that the valve membrane 10 squeezes the urethra 12, so that the urethra 12 is closed. When pressing the hand pressure film 1, the plunger 4 moves downward, making the pressure-bearing film 3 protrude downward. At this time, the volume of the pump chamber becomes smaller and the pressure becomes larger; The chamber communicates with the valve body 9, so that the working medium 7 in the valve body 9 flows into the lower chamber, at this time, the pressure of the working medium 7 on the valve membrane 10 becomes smaller, causing the urethra 12 to open, thereby realizing urination.

In order to ensure the sealing of the pump chamber and the lower housing chamber, a sealing ring 5 can be used between the cover of the pump 6 and the plunger 4 to ensure that the working medium 7 does not enter the pump chamber. The pump body 2 and the pump cover 11 can be arranged integrally, so that the structure of the pump body 2 and the pump cover 11 is reliable, and the pump chamber and the lower containing chamber are effectively separated.
