Problems solved by technology
[0002] Existing hospital patients need urethral drainage of urine to a urine bag. The length of the existing catheter is relatively long. , the height of the urine bag is higher than the urethral opening, which can easily cause urine reflux and risk of infection
[0003] If a one-way valve is directly added to the catheter to prevent urine backflow, because the existing one-way valve works through the pressure difference at both ends of the valve, so when the height of the urine bag is higher than the collection When the height of the urine cavity is high, the pressure difference between the two ends of the one-way valve will be too small and the one-way valve cannot be opened, so the urine in the urethra cannot be well transported into the urine bag.

[0026] As an improved specific implementation, the drive circuit 3122 includes a capacitor 31222, a switch tube 31223 and a detachable button battery 31221 connected to the casing 3121, and the control end of the switch tube 31223 is coupled behind the graphene powder Coupled to the positive pole of the button battery 31221, the control terminal is also coupled to the capacitor 31222 and then coupled to the negative pole of the button battery 31221, the first end of the switch tube 31223 is coupled to the positive pole of the button battery 31221, and the second end is coupled to the positive pole of the button battery 31221. After being connected to the vibrator 3123, it is coupled to the negative pole of the button battery 31221, so that the conditional conduction characteristic of the switch tube 31223 can be used to realize the vibration effect of the vibrator 3123 when the resistance of the sensor changes to a certain degree, effectively realizing The effect of reminding w...

The invention discloses a backflow-proof urine storage device, wherein a temporary storage part used for storing urine temporarily is arranged on a catheter on a position close to a urine collection chamber, and a first one-way valve is arranged at the end of the temporary storage part close to the urine collection chamber, and the opposite end is provided with a second one-way valve; a pressurized structure comprises a gasbag, a third one-way valve and a fourth one-way valve, and one end of the gasbag is fixedly connected with the temporary storage part, and is communicated with the interior of the temporary storage part, the third one-way valve is arranged on the position where the gasbag is connected with the temporary storage part, an air port is formed in the end, back to the temporary storage part, of the gasbag, and the fourth one-way valve is arranged in the air port. According to the backflow-proof urine storage device, back flow can be effectively prevented through the arrangement of four one-way valves, and through the arrangement of the pressurized structure and the temporary storage part, the effect of the bladder of the human body can be achieved in cooperation with the pressurized structure and the temporary storage part, so that the patient can urinate better.
Description
technical field [0001] The invention relates to a medical device, in particular to an anti-backflow urine storage device. Background technique [0002] Existing hospital patients need urethral drainage of urine to a urine bag. The length of the existing catheter is relatively long. , the height of the urine bag is higher than the urethral opening, which can easily cause urine reflux and risk of infection. [0003] If a one-way valve is directly added to the catheter to prevent urine backflow, because the existing one-way valve works through the pressure difference at both ends of the valve, so when the height of the urine bag is higher than the collection When the height of the urine cavity is high, the pressure difference between the two ends of the one-way valve is too small and the one-way valve cannot be opened, so the urine in the urethra cannot be well transported into the urine bag. Contents of the invention [0004] In view of the deficiencies in the prior art, t...
