Abstract

The invention provides an easy-plug urinary catheter and a spring part and belongs to the field of medical instruments. The easy-plug urinary catheter comprises a urinary catheter body and the spring part, wherein one end of the urinary catheter body is provided with air inflation and water filling port and a urine outlet, and the other end of the urinary catheter body is provided with a urine inlet and a fixed air bag; a first pipeline and a second pipeline are arranged in the urinary catheter body, the air inflation and water filling port is communicated with the fixed air bag through the first pipeline, and the urine outlet is communicated with the urine inlet through the second pipeline; the spring part is arranged in the urinary catheter body and located at urine inlet end of the urinary catheter body. The easy-plug urinary catheter has the advantages that the spring part is arranged in the urinary catheter body and can increase the overall hardness of the urinary catheter body to allow the urinary catheter body to be smoothly inserted into the urethra; the urinary catheter is simple in structure, low in cost and capable of being used as a disposable product; a sterilizing procedure is omitted, sanitation standards are increased, and use safety is increased.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an easy-to-plug urinary catheter and a spring member. Background technique [0002] Urinary catheterization is one of the common clinical medical operations. Urinary catheters are often used to help patients collect urine or help patients with inconvenient movements such as postoperative urination. It is also suitable for urinary retention caused by lower urinary tract obstruction. Urinary catheterization is also It is used in rescue of critically ill patients, preparation before general anesthesia, intravesical drug infusion or bladder flushing, etc. [0003] The urinary catheter generally includes a urinary catheter and an air bag arranged on the catheter. The urine inlet is located at the end of the catheter. When inserting the catheter, extend the end of the catheter into the urinary tract. , Inflate or inject water into the airbag, use the inflated or water-filled airbag ...
