AI Technical Summary

Technical Problem

Existing catheters are prone to urethral damage when the patient is unconsciously stretched, and it is difficult for nursing staff to detect it in time, leading to hematuria and affecting the patient and nursing work.

Method used

Design a dual-airbag anti-pull protection catheter, including a hose, a dual-airbag group and a pressure receptor. By installing a pressure receptor at the end of the branch airbag of the urethra, the dual airbag group can reduce urethra compression when traction is detected, and through the alarm and automatic exhaust function of the pressure receptor, medical staff are reminded to deal with it in time.

Benefits of technology

It effectively reduces the damage to the urethra during catheter pulling, provides medical staff with time to detect and deal with the urethra early, and uses the automatic exhaust function to smoothly slide the catheter out of the urethra, reducing the risk of urethra damage.

Abstract

The embodiment of the present invention discloses a double-balloon anti-pull protection type urinary catheter, including a hose, a double-balloon group and a pressure sensor, the open end of the hose is connected to a urine bag, and a "Y"-shaped branch is formed on the tube body at the open end of the hose, the double-balloon group includes a first balloon and a second balloon arranged side by side along the tube body at the closed end of the hose, the second balloon is connected to the water injection end of the branch in the hose, and the first balloon and the second balloon are unidirectionally connected inside the hose, so that gas can flow from the second balloon to the first balloon, the pressure sensor is installed at the balloon end of the branch, the first balloon and the second balloon are unidirectionally connected to the inside of the pressure sensor respectively, so that gas can flow from the first balloon or the second balloon to the inside of the pressure sensor, and the pressure sensor displays the pressure state of the balloon. The present invention can reduce damage after the urinary catheter is indwelled, and provide time for medical staff to early discover and deal with phenomena such as urinary catheter traction.
