Male indwelling urethral catheterization device

Abstract

The invention relates to an indwelling urinary catheterization device for men, belonging to the technical field of medical aids. The male indwelling catheterization device of the present invention comprises a catheter whose one end can be inserted into the bladder through the urethra and is matched with the urethra to prevent detachment, and the other end of the catheter is provided with an annular flexible body for blocking the opening of the external urethra. The urinary catheter of the male indwelling catheterization device of the present invention is provided with an annular sac cavity, which can block the urethral opening after the annular sac cavity is inflated, fundamentally avoiding the leakage of urine from the urethral opening. Further, the end of the catheter used for inserting into the bladder through the urethra is provided with an inner capsule that can be inflated to prevent disengagement from the urethra, and cooperates with the annular flexible body to generate a pulling effect to prevent the inner capsule from floating in the bladder, making the inner capsule The cyst is close to the internal opening of the urethra.

Description

technical field [0001] The invention relates to an indwelling urinary catheterization device for men, belonging to the technical field of medical aids. Background technique [0002] Clinically, indwelling catheterization is often performed for patients with voiding dysfunction or other diseases, usually by inserting one end of the catheter into the bladder and connecting the other end with a urine collection bag. Patients with long-term indwelling urinary catheters will have different degrees of urine leakage and extravasation due to the relaxation of the urethral opening. cause discomfort to the patient. [0003] The Chinese utility model patent (the authorized announcement number is January 22, 1997) with the authorized announcement number CN2245462Y discloses a controllable urination catheter. It is a urinary catheter connected with the catheter hole and an inflatable tube connected with the stomata. The front side of the composite pipe is provided with a catheter port ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned urinary-airway composite tube can fix one end inserted into the bladder to prevent the urine-gas composite tube from falling off. However, gaps are likely to appear between the tube wall of the urine-gas composite tube and between the air bag and the urethral wall, and the urine in the bladder is easy to leak. Exudation from the gap between the compound tube and the urethra

Clinically, cotton diapers or tapes are often used to block the external urethral opening. However, local leakage of urine can easily soak the cotton diaper or cause the diaper to fall off, which still cannot solve the problem of urine leakage, and clinical complications are likely to occur: such as Issues related to infection, diminished patient comfort, and increased difficulty of care

In particular, for patients who have been using the urine-gas composite tube for a long time, due to the looseness of the urethral orifice, gaps are likely to appear between the outer wall of the composite tube and the urethral wall, and it is more likely to cause urine to leak from the urethral orifice or the gap between the composite tube and the urethra.
