Problems solved by technology

[0002] At present, the catheters used clinically are all catheters with balloons. After the catheter is inserted into the urethra, 10ml of air or normal saline is usually injected into the balloon with a syringe, so that the balloon is filled and floated in the bladder to fix the urinary bladder. As the time of indwelling the urinary catheter increases, the air or saline in the air bag will decrease, causing the air bag to shrink. To a certain extent, the catheter will slip out of the urethra, and the catheter needs to be reinserted, thus Increased patient suffering and chances of urinary tract infection

Abstract

The invention relates to the technical field of catheterization devices, and particularly relates to an airbag catheter which comprises an inflation tube. A catheter is arranged in the inflation tube.The two ends of the inflation tube are sealed. The two ends of the catheter penetrate through the two ends of the inflation tube. An airbag is arranged at the tail end of the inflation tube. The interior of the airbag is communicated with the inflation tube. A three-way pipe is connected with the middle of the inflation tube. A connector at one end of the three-way pipe is communicated with the inflation tube. A connector on one side of the three-way pipe is connected with an injection device. The injection device comprises a liquid storage pipe. An air cylinder is arranged at one end of theliquid storage pipe. A buzzer is arranged at the top of the three-way pipe. An air pressure sensor is arranged on the inner wall of the three-way pipe. By means of the design, when the pressure in theairbag is lower than the normal range, it can be prompted that the airbag is shrunk and the catheter slips off. Normal saline can be injected into the normal range, and the backflow speed of the normal saline in the airbag can be reduced through a blocking piece.

Description

technical field [0001] The invention relates to the technical field of urinary catheterization devices, in particular to an air bag urinary catheter. Background technique [0002] At present, the catheters used clinically are all catheters with balloons. After the catheter is inserted into the urethra, 10ml of air or normal saline is usually injected into the balloon with a syringe, so that the balloon is filled and floated in the bladder to fix the urinary bladder. As the time of indwelling the urinary catheter increases, the air or saline in the air bag will decrease, causing the air bag to shrink. To a certain extent, the catheter will slip out of the urethra, and the catheter needs to be reinserted, thus Increase the patient's suffering and the chance of urinary tract infection. Contents of the invention [0003] The object of the present invention is to provide a balloon urinary catheter to solve the problems raised in the above-mentioned background technology. [0...
