Abstract

The invention provides a catheter, and relates to the technical field of medical apparatuses and instruments. The catheter comprises a main pipe and multiple air sacs located on the head of the main pipe; the multiple air sacs are arranged on the outer wall of the main pipe, and are arranged in the circumferential direction of the main pipe at intervals; a drainage channel and multiple water injection channels are formed inside the main pipe; drainage holes communicated with the drainage channel are formed between the air sacs on the main pipe, and the end, away from the air sacs, of the drainage channel is communicated with the outside; the multiple water injection channels are communicated with the multiple air sacs, and each water injection channel is communicated with at least one airsac. When one or more air sacs are leaked, the rest of non-leaked air sacs can continue to normally work to guarantee that the main pipe continues to relatively fix to the bladder, and it is guaranteed that the drainage holes are located inside the bladder.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a urinary catheter. Background technique [0002] A urinary catheter is a tube inserted from the urethra into the bladder to drain urine. It is a tube made of natural rubber, silicone rubber, or polyvinyl chloride. It can be inserted into the bladder through the urethra to drain urine. [0003] In the prior art, after the catheter is inserted into the bladder, in order to fix the catheter and stay in the bladder, an air bag is provided near the head of the catheter, and water is injected into the air bag through the water injection channel, and the air bag is stuck in the body after water injection and expansion , and finally the drainage tube leads the urine in the bladder out through the drainage hole. [0004] However, when the water injection channel valve is damaged or the air bag leaks, it is easy to cause the catheter to come out of the body. Contents of the...
