Problems solved by technology

Although the urinary catheter provided by this invention can clean the urethra, the irregular outer wall of the urinary catheter is easy to cause discomfort to the patient after being inserted into the urethra, and the cleaning cavity and the drainage cavity can pass through the first passage, the second The two channels are indirectly connected. When the urine is discharged, it is easy to enter the cleaning channel and contaminate it, thus affecting the subsequent cleaning operation of the cleaning channel.

Abstract

An indwelling catheter and a catheter assembly belong to the field of catheters in clinical urology. The indwelling catheter includes a catheter body, the end of the catheter body is provided with a catheter hole and an indwelling bladder that can expand and contract, the indwelling bladder is provided with a cavity, and the front end of the catheter body is provided with a catheter The catheter interface connected with the hole and the capsule interface connected with the indwelling capsule body, the outer wall of the catheter body is provided with a groove, the catheter body is provided with a cleaning channel connected with the groove, and the catheter body is far away from the catheter hole One end is provided with a cleaning port communicating with the cleaning channel. The indwelling catheter can effectively wash and disinfect the urethra of patients with the indwelling catheter, and can prevent, reduce and treat urinary tract infection. The present invention also provides a urinary catheter assembly with the above-mentioned indwelling catheter.

Description

technical field [0001] The invention relates to the field of clinical urology catheters, in particular to an indwelling catheter and a catheter assembly. Background technique [0002] Indwelling urinary catheter is a commonly used medical device, which is mainly used to help patients who cannot take care of their own urine to discharge urine. Commonly used indwelling catheters generally include a catheter body with a catheter hole at the end and a hollow balloon body that can be expanded and contracted. When using, insert the end of the catheter body into the patient's bladder through the urethra, and use the balloon interface to introduce normal saline or gas into the hollow balloon, so that the balloon is inflated and then fixed in the bladder to define the guide. The position of the urinary catheter body ensures that the urinary catheter body can be stably inserted into the patient's body for a long time, and then the urine of the patient is discharged through the urinat...
