Description

Leak-proof pressure measuring type catheter

Technical Field

The invention relates to the technical field of medical instruments, in particular to a leak-proof pressure measuring type catheter.

Background

The urinary catheter is a common medical device which can be inserted into the bladder through the urethra so as to drain urine, and after the urinary catheter is inserted into the bladder, an air bag is sleeved at the end point close to the urinary catheter to fix the urinary catheter to stay in the bladder and prevent the urinary catheter from falling off. Aiming at patients with urethral stricture, bladder perforation and urethral fistula, a ureter is required to be placed for determining the cause of disease, and then a contrast agent is injected through the ureter by using an injector to carry out urethral cystography; aiming at patients with organ bleeding such as kidney, bladder, prostate and the like or after operation, the utility model is used for preventing blood clots from accumulating in the bladder. After the urinary retention is placed into a urinary catheter, the flushing device is used for flushing the bladder continuously; aiming at patients with bladder cancer, leukoplakia of bladder mucosa, glandular cystitis and the like, a urinary catheter is required to be placed periodically after operation in order to reduce the recurrence risk, and a medicament is injected into the urinary catheter by using an injector to perform bladder perfusion treatment, wherein the urinary catheter is one of indispensable medical instruments for treating a plurality of diseases;

bladder pressure normal range is between 0-5cmho, can press the condition of understanding kidney function through the bladder clinically, can assist the diagnosis of disease, need carry out the row pressure when the bladder internal pressure is too high, need medical personnel to observe the manual row pressure constantly when the bladder internal pressure is too high, can't carry out row pressure automatically, and the catheter that uses at present does not connect the joint of piezometric pipe, so can only take off the urine bag when needing to connect the piezometric pipe, connect the piezometric pipe on the urine bag joint, connect the urine bag after the survey, such operation easily causes the pollution, make patient's bladder infect, and the process of taking off the urine bag also can cause the urine in the catheter to omit, cause the pollution of surrounding environment.

Based on the above, the invention designs a leak-proof pressure measuring type urinary catheter to solve the above problems.
