[0046] Furthermore, an annular embedding groove 39 is provided on the top of the movable valve plate 37, and a second sealing ring 310 is installed in the annular embedding groove 39 to ensure the sealing between the movable valve plate 37 and the hollow housing 31. Specifically, a gas flow groove 38 is provided on the outer side of the movable valve plate 37.
[0047] The working process of the urine collection device for urological laparoscopy of the present invention is as follows:
[0048] When the urine collection device is not in use, the sealing plug 28 of the urine storage assembly 2 is installed on the female connector 27, and the first valve is closed. Under the action of the first helical spring 113, the lower part of the movable ring 110 of the urine receiving assembly 1 rests against the positioning step 117, and the first sealing ring 111 is in close contact with the top sealing cover 21 of the urine storage assembly 2. Under the action of the second helical spring 312, the movable valve plate 37 of the gas flow control assembly 3 rests against the top wall of the movable cavity 33 of the second component, and the second sealing ring 310 is pressed against the top wall of the movable cavity 33 of the second component, and the second valve is in the closed state.
[0049] When the urine collection device collects urine, the third docking channel 36 of the gas flow control component 3 is connected to the air pump pipe, the sealing plug 28 is pulled out from the female connector 27, the female connector 27 is connected to the catheter in urological laparoscopy, and the first valve is opened. When the air pump is activated, the gas in the two-component movable chamber 33 is sucked away, creating a negative pressure environment in the two-component movable chamber 33. The movable valve plate 37 moves downward, creating a gap between the second sealing rings 310 and the top wall of the second-component movable chamber 33. The gas in the airbag receiving chamber 112 is sucked away through the first gas flow hole 19, the negative pressure environment chamber 14, the first docking channel 18, the second gas flow hole 34, the gap between the second sealing rings 310 and the top wall of the second-component movable chamber 33, the gas flow groove 38, the second-component movable chamber 33, and the third docking channel 36, thus creating a negative pressure environment in the airbag receiving chamber 112. Under the action of the negative pressure environment, the urine collection airbag 23 increases in volume, creating a negative pressure environment in the urine storage chamber 24. The urine enters the urine storage chamber 24 of the urine collection airbag 23 through the catheter, female connector 27, and catheter tubing 26 used in urological laparoscopy.
[0050] After urine collection is completed, the first valve of the urine storage component 2 is closed, the female connector 27 is connected to the sampling port of the sampling tank, the first valve is opened, the second valve of the gas flow control component 3 is opened, and the longitudinal pull rod 311 is pulled down. External gas enters the airbag receiving chamber 112 through the fourth docking channel, the second component moving chamber 33, the gas flow groove 38, the gap formed between the second sealing ring 310 and the top wall of the second component moving chamber 33, the second gas flow hole 34, the first docking channel 18, the negative pressure environment chamber 14, and the first gas flow hole 19. The airbag receiving chamber 112 is no longer a negative pressure environment, the urine collection airbag 23 elastically resets, and the volume of the urine collection airbag 23 decreases. The urine in the airbag receiving chamber 112 enters the sampling tank through the second docking channel 25, the catheter 26, the first valve, and the female connector 27, completing the sampling work.
[0051] Recover the urine storage component 2, close the second valve, remove the bolts and fasteners at the upper connecting ear 22 and the lower connecting ear 13, lift the top sealing cover 21 upwards, remove the urine collection airbag 23 from the airbag receiving cavity 112, and place the urine storage component 2 at the collection point.
[0052] The urine collection device for urological laparoscopic surgery of the present invention uses a disposable urine storage component 2. It utilizes a structure and air pump to collect urine under negative pressure. After urine collection, the urine is sampled using the elastic deformation characteristics of the urine collection balloon 23. After sampling, the disposable urine storage component 2 is directly discarded, ensuring that all structures in contact with urine are discarded, thus preventing urine contamination of other structures. During urine sampling, there is no need to manually disassemble the sampling balloon, avoiding urine contamination of other structures.
[0053] The urine collection device for urological laparoscopic surgery of the present invention has a simple structure and is easy to operate. It can realize two processes: urine collection and urine sampling, and has a high degree of integration. After the urine sampling is completed, only the disposable urine storage component 2 needs to be discarded, and the other structures can continue to be used, which is low in cost.
[0054] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
