Manual pump controlled urethra valve

Abstract

The invention discloses a manual pump controlled urethra valve which comprises a pump body and a valve body, wherein a hand pressure membrane and a pressure-bearing membrane are respectively arranged at the upper and lower ends of the pump body; a pump cover used for segmenting the pump body into a pump chamber and lower containing chambers is arranged in the pump body; two ends of a plunger are respectively connected to the hand pressure membrane and the pressure-bearing membrane, and the volume of the two containing chambers can be changed by moving the plunger; a through hole used for allowing the plunger to penetrate is formed in the pump cover; incompressible working media are arranged in the lower containing chambers; the valve body is communicated with the lower containing chambers; a valve membrane positioned on one side of the urethra is arranged on the valve body, and a valve cover with a fixed position is arranged on the other side of the urethra; the urethra can be closed by the valve membrane and the valve cover; when the hand pressure membrane is pressed, the volume of the containing chamber is increased, the working media in the valve body enter the lower containing chamber, the pressure of the valve membrane on the urethra is reduced, and then the urethra is opened. According to the urethra valve disclosed by the invention, the valve membrane and valve cover made of medical elastic materials are contacted with the outer wall of the urethra, the pressure for closing the urethra is uniform in distribution, and mechanical injuries of organs and tissue necrosis caused by unsmooth blood circulation are avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a manual pump-controlled urethral valve. Background technique [0002] 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.

AI Technical Summary

Problems solved by technology

Conservative treatment such as medicine or traditional Chinese medicine is only suitable for patients with mild urinary incontinence, and the effect is not good for patients with moderate and severe urinary incontinence

Surgical treatment is susceptible to 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 not yet clear

Nursing measures can only alleviate the symptoms of urinary incontinence, but cannot solve the problem of urinary incontinence from the source of the disease
