1. the physiological saline is injected from the flushing pipe, after the physiological saline is flushed out of the flushing pipe, the flushing pipe is blocked by the inner urethral orifice and the air bag, the urinary secretion is not brought into the bladder, the flushing liquid flows back into the urethra along the inner urethral orifice, along with the increase of the physiological saline, the physiological saline props the urethra to flow downwards to the position at the upper end of the return pipe, the physiological saline flows out of the return pipe to complete the circulation of flushing the urethra, and the secretion in the urethra can be drained by the method.
2. Through the back flow drainage, prevent that the normal saline who washes the urethra from dashing the urethral orifice and flowing out to avoid normal saline turbulent flow to be inconvenient for the clearance.
3. Under the blockage of the inner orifice of the urethra and the air sac, normal saline does not flow into the bladder, can only prop the urethra downwards, and helps the urethra to stretch and move so as to wash away dirt, bacteria and viruses clamped on the side wall of the urethra.
Preferably, as an improvement, the sterilizing filter screen is wrapped on the outer side of the urinary catheter, and the upper end of the return pipe is clamped between the sterilizing filter screen and the urinary catheter. So arranged, after the urethra is washed by normal saline, the normal saline passes through the disinfection filter screen and then flows into the return pipe; the large scale dirt can not be washed out by normal saline, and after the large scale dirt is left on the disinfection filter screen, bacteria and viruses on the large scale dirt are difficult to survive and kill on the disinfection filter screen, so that the urethra health of a patient is ensured.
Preferably, as an improvement, the modified cotton fabric of the nano titanium dioxide is modified on the outer side of the disinfection filter screen to form a hydrophobic surface, and the long-chain unsaturated fatty acid is modified on the inner side of the disinfection filter screen to form a hydrophilic surface. So set up, there is the following effect:
1. the disinfection filter screen is a modified cotton fabric with the surface modified with nano titanium dioxide, and has antibacterial function and super-hydrophilic performance. On the basis, the long-chain unsaturated fatty acid is modified on the other side of the sterilizing filter screen to endow the sterilizing filter screen with hydrophobic performance, so that the sterilizing filter screen has unidirectional wetting performance, namely secretion can permeate from the hydrophobic surface to the hydrophilic surface and wet the sterilizing filter screen, and when the sterilizing filter screen contacts the hydrophilic surface, the secretion can be directly spread and wetted and cannot permeate the hydrophobic surface, so that unidirectional fluidity is realized.
2. Based on the effect 1, normal saline can only flow into the return pipe from the urethra through the sterilizing filter screen, but can not flow back, so that dirt is prevented from being flushed back into the urethra when more normal saline exists.
Preferably, as a modification, the two reflux pipes are arranged, and the part of the reflux pipe clamped between the sterilizing filter screen and the urinary pipe is provided with small holes. So set up, normal saline not only can flow out through the back flow upper end after passing through disinfection filter screen, still can flow out through the aperture, has increased the speed of backward flow to abluent efficiency has been increased.
