Safety-type three-cavity balloon catheter

Abstract

The invention provides a safety-type three-cavity balloon catheter. The safety-type three-cavity balloon catheter comprises a pipe body, wherein a branching pipe is arranged at the bottom of the pipe body; and a medical non-return valve is arranged at the pipe orifice of the branching pipe. When the safety-type three-cavity balloon catheter is in use, as the branching pipe is arranged at the bottom of the pipe body, and the medical non-return valve is arranged at the pipe orifice of the branching pipe and matched with an infusion apparatus connector, so that infusion by a needle head is not required, and the pipe body is prevented from being punched; and the medical non-return valve can be kept closed, and an infusion apparatus is unobstructed after being connected with the medical non-return valve in a pressing manner and keeps the urinary catheter closed after being pulled out to effectively prevent retroinfection. The safety-type three-cavity balloon catheter is convenient to operate and less in operation steps, and is directly connected with the washing fluid infusion apparatus to realize needle-free use, and the safety valve is used for preventing leakage and infection.

Description

technical field [0001] The invention relates to a medical product, in particular to a safe three-chamber air bag urinary catheter. Background technique [0002] The catheter is a tube made of natural rubber, silicone rubber or polyvinyl chloride (PVC), which can be inserted into the bladder through the urethra to drain urine out. After the catheter is inserted into the bladder, there is a balloon near the tip of the catheter The fixed urinary catheter stays in the bladder and is not easy to come out, and the drainage tube is connected to a urine bag to collect urine. [0003] Indwelling catheters include double-chamber and triple-chamber balloon catheters, and triple-chamber balloon catheters are widely used in urological surgery for benign prostatic hyperplasia, prostate cancer, bladder tumors and other diseases for continuous bladder irrigation after resection; double-chamber catheters are more Applied to patients with long-term indwelling catheterization.

AI Technical Summary

Problems solved by technology

[0004] One lumen of the three-chamber balloon catheter is an airbag, the other lumen is connected to the urine bag, and the other lumen is open when not in use, resulting in urine leakage and infection, and the design of the flushing lumen is connected with the drainage bag and infused The nipple of the catheter is not matched and there is no sealing device, so it cannot be used for patients with long-term indwelling catheterization; one cavity of the double-chamber balloon catheter is an airbag, and the other is connected to a urine bag. When patients with long-term indwelling catheterization perform bladder irrigation to prevent urinary tract infection The lumen of the urinary catheter needs to be sterilized and then punctured with a needle. Repeated punctures are prone to urinary leakage or needle stick injuries, and the nursing procedures are cumbersome. During the operation, urine often easily contaminates hands and bed sheets Yuan

[0005] In order to solve the above-mentioned problems in bladder flushing of patients with indwelling catheterization, after consulting relevant literature: many literature reports improved the disposable drainage bag to make the drainage bag meet the requirements of the catheter, and added a flushing connector to the drainage hose of the drainage bag. The operation is still not simple enough, and because the drainage bag needs to be replaced regularly, it also increases the cost while simplifying the operation steps; there are also reports in the literature that a self-made connector is connected to the irrigation end of the catheter, and one end is connected to the catheter and the other end is connected to the infusion set for irrigation fluid. Although this method reduces the risk of acupuncture, other related problems still exist; there are also reports in the literature that a heparin cap is added to the flushing end of the three-chamber balloon catheter. This method still needs to be punctured with a needle. Tubes may not be completely matched, prone to leakage of urine
