Urethral catheter device and using method thereof

Abstract

The invention provides a urethral catheter device and a using method thereof, and relates to the field of medical instruments. The urethral catheter device comprises a silica gel catheter, a fixing balloon is arranged on the silica gel catheter, and a pressure sensing device is installed at the joint of the fixing balloon and the silica gel catheter. The using method of the urethral catheter comprises the following steps that S1, whether the appearance of the catheter is intact or not is checked, water is injected into the fixing balloon, and the water is pumped out after the integrity of the fixing balloon is confirmed. According to the urethral catheter device and the using method thereof, a pressure display device becomes green with lower pressure in the bladder area to prompt that the pressure sensing device enters the bladder, that is, the fixed balloon at the front end of the pressure sensing device reaches the bladder, so that the position of the fixed balloon reaching the bladder can be determined as much as possible, and the balloon avoids the situation that water is injected into the urethra as much as possible, therefore the possibility that the urethra is torn when the urethral catheter is inserted is greatly avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a urinary catheter device and its usage method. Background technique [0002] A urinary catheter is a tube inserted through the urethra into the bladder to drain urine. It is a tube made of natural rubber, silicone rubber or polyvinyl chloride (PVC), which can be inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, there is a balloon near the tip of the catheter to fix the catheter The tube stays in the bladder and does not come out easily, and the drainage tube is connected to a urine bag to collect urine. [0003] The current urinary catheter can be used for catheterization very well, but when in use, because the pressure of the urethra and bladder are different, each position is different, there will be a gap, which makes it difficult to determine the ball Whether the sac has reached the bladder, if it has not...

Problems solved by technology

[0003] The current urinary catheter can be used for catheterization very well, but when in use, because the pressure of the urethra and bladder are different, each position is different, there will be a gap, which makes it difficult to determine the ball Whether the sac has reached the bladder, if it has not reached the bladder, inject water directly into the urethra, the urethra is relatively narrow when the sac is bulging, and the urethra may tear if there is no space
