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.

specific Embodiment approach
[0026] As an improved specific embodiment, the driving circuit 3122 includes a capacitor 31222, a switch tube 31223, and a button battery 31221 detachably connected to the housing 3121. The control end of the switch tube 31223 is coupled to the graphene powder. Coupled to the positive electrode of the button battery 31221, the control terminal is also coupled to the capacitor 31222 and then coupled to the negative electrode of the button battery 31221. The first end of the switch tube 31223 is coupled to the positive electrode of the button battery 31221, and the second end is coupled After being connected to the vibrator 3123, it is coupled to the negative electrode of the button battery 31221. In this way, the conditional conduction characteristics of the switch tube 31223 can be used to realize the effect of vibrating the vibrator 3123 when the sensor resistance changes to a certain degree. The effect of the reminder after the urine bag 3 is full.

The invention discloses an anti-backflow urine storage device. A temporary storage part for temporary storage of urine is provided on the position of the catheter close to the urine collection cavity, and a second storage part is provided at the end of the temporary storage part close to the urine collection cavity. A one-way valve, the opposite end is provided with a second one-way valve, the pressurized structure includes an air bag, a third one-way valve and a fourth one-way valve, one end of the air bag is fixedly connected to the temporary storage part, and It communicates with the interior of the temporary storage part, the third one-way valve is set at the position where the airbag is connected to the temporary storage part, an air vent is opened at the end of the airbag facing away from the temporary storage part, and the fourth one-way valve is set inside the vent. The anti-backflow urine storage device of the present invention can effectively prevent backflow through the setting of four one-way valves, and through the setting of the pressurized structure and the temporary storage part, it can cooperate to realize the effect of the human bladder, so that the patient can be more Good to urinate.
Description
Technical field [0001] The invention relates to a medical device, and more specifically to a backflow prevention urine storage device. Background technique [0002] Existing hospital patients need to urethra to drain urine to the urine bag. The existing urinary catheter is long. When the patient goes out for a walk, when carrying the urine bag, the catheter is longer and will drag to the ground. In addition, when carrying the urine bag The height of the urine bag is higher than the urethral opening, which is easy to cause urine reflux and risk of infection. [0003] If a one-way valve is directly added to the urinary catheter to prevent the backflow of urine, since the working principle of the existing one-way valve is realized by the pressure difference between the two ends of the valve, when the height of the urine bag is higher than the set When the urine cavity is high, there will be a problem that the pressure difference between the two ends of the one-way valve is too small ...
