Catheter

Abstract

The invention discloses a catheter and relates to the field of medical instruments. The catheter comprises a tube body, a closed airbag is arranged at an insertion part of the tube body, and communicated with an indication valve arranged outside the tube body through an air feeding tube; a side wall communicating tube which is communicated with tube body is arranged at a connecting part of the side wall of the tube body and a drainage pack; and a plug lid is arranged at the port of the side wall communicating tube. The catheter can solve the problems that the catheter damage is caused easily and nurse occupational injuries and workloads are increased to increase the cost and pain of a patient because the bladder pressure only can be measured after a syringe needle is required to puncture a tube cavity at the connecting part of the catheter and the drainage pack and then an infusion tube is connected when the patient needs to measure the bladder pressure during the indwelling period of the catheter.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a catheter for urine drainage. Background technique [0002] Disposable catheters currently in use include common disposable double-lumen catheters for drainage of urine and triple-lumen catheters for flushing. Common double-lumen catheters are simply used for indwelling catheters Drainage of urine, three-lumen catheter is generally indwelling after urological surgery to flush the bladder, etc. If the patient needs to measure the bladder pressure during the indwelling of the existing double-lumen catheter, a disposable needle is used to puncture the lumen at the junction of the catheter and the disposable drainage bag, and then the infusion tube is connected to measure the bladder pressure. To measure bladder pressure, it is necessary to repeatedly puncture the urinary catheter with a disposable needle. For example, although a three-lumen catheter can be directly connec...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a urinary catheter, which can solve the problem that when the patient needs to measure the bladder pressure during the indwelling catheter, it is necessary to use a needle to puncture the lumen at the junction of the catheter and the drainage bag, and then connect the infusion tube. Only when the bladder pressure can be measured, it is easy to cause damage to the catheter, increase the occupational injury and workload of the nurse, and increase the cost and pain of the patient.
