Description

Novel catheter bracket

Technical Field

The utility model relates to the technical field of medical equipment, specifically a novel catheter support.

Background

The medical apparatus refers to instruments, equipment, appliances, in-vitro diagnostic reagents and calibrators, materials and other similar or related articles directly or indirectly applied to the human body, and comprises required computer software, wherein the effects are mainly obtained in a physical mode and other modes, not in a pharmacological, immunological or metabolic mode, or are only assisted by the modes, so that the diagnosis, prevention, monitoring, treatment or alleviation of diseases are achieved; diagnosis, monitoring, treatment, mitigation, or functional compensation of injury; examination, replacement, regulation or support of a physiological structure or physiological process; support or maintenance of life; controlling pregnancy; by examining a sample from a human body, information is provided for medical or diagnostic purposes.

Catheterization is the most common basic operation in clinic, and most of the prior common urinary catheters made of rubber or silica gel reach the bladder through the urethra to conduct catheterization. With the gradual aging of the population of China, the number of the aged men is increased, and the population of the aged men almost inevitably suffers from prostatic hyperplasia. Due to various reasons such as lengthening, narrowing and bending of the posterior urethra caused by prostatic hyperplasia, elevation of the bladder neck, stricture of the posterior urethra, bladder neck spasm caused by acute urinary retention and the like, the common catheter can not continue to advance when reaching the posterior urethra, and urethral catheterization failure and urethral mucosa injury are often caused.

Although the prior invention designs the metal catheter bracket, the metal catheter bracket needs rich experience of an operator, so that the popularization rate of the metal catheter bracket is limited, the urethral false passage or prostate injury bleeding is easily caused by using the metal catheter bracket, and finally a patient has to undergo operations such as cystostomy and the like to perform urine drainage, so that the pain of the patient is increased, the treatment and hospitalization time is prolonged, and the pain and the economic burden of the patient are increased. More seriously, urethral stricture may occur after the urethra is damaged by the metal catheter bracket of some patients, and further treatment is needed. In addition, when the metal catheter bracket is withdrawn from the catheter, the catheter is connected with the gap of the drainage bag, and the urine often wets clothes, bed sheets and the like of a patient, so that the discomfort of the patient is increased.
