Specifically, the urine collection bladder 23 is an elastic member and is located within the bladder accommodating chamber 112. More specifically, a urine storage chamber 24 is defined within the urine collection bladder 23, which communicates with the second docking channel 25. More specifically, the urine storage assembly 2 also includes a sealing plug 28 mounted on the female connector 27.

[0028] Furthermore, a valve No. 1 is provided at the female connector 27 connected to the urinary catheter hose 26. An upper connecting ear 22 is provided on the outside of the top sealing cover 21, and through holes are provided on the upper connecting ear 22 and the lower connecting ear 13. Bolts are inserted into the through holes of the upper connecting ear 22 and the lower connecting ear 13, and the protruding ends of the bolts are installed with washers and nuts.

[0029] like Figure 7-Figure 8 The gas flow control assembly 3 includes a hollow housing 31, which has a second active chamber 33 inside. A second gas flow hole 34 is provided at the top of the hollow housing 31, connecting to the second active chamber 33. The second gas flow hole 34 is connected to the first docking channel 18. A movable valve plate 37 and a second coil spring 312 are installed within the second active chamber 33. The top of the second coil spring 312 is connected to the movable valve plate 37, and the bottom is connected to the inner wall of the second active chamber 33. The bottom of the movable valve plate 37 is connected to a longitudinal valve stem 311, and the bottom of the longitudinal valve stem 311 extends out of the hollow housing 31. Specifically, a rod through-hole 35 is provided at the bottom of the hollow housing 31, through which the longitudinal valve stem 311 passes, with the bottom of the longitudinal valve stem 311 exposed outside the hollow housing 31. A third docking channel 36 is provided at the bottom of the hollow housing 31, connecting to the second active chamber 33. The third docking channel 36 is connected to the air pump. A fourth docking channel, connecting to the second active chamber 33, is provided at the bottom of the hollow housing 31. Valve No. 2 is installed at this docking channel.

[0030] 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.

[0031] The working process of the urine collection device during urological laparoscopy of the present invention is as follows: When the urine collection device is not in use, the sealing plug 28 of the urine storage assembly 2 is installed in the female connector 27, and valve No. 1 is closed. Under the action of coil spring No. 1 113, the lower portion of the movable ring 110 of the urine storage assembly 1 presses against the positioning step 117, and the first sealing ring 111 tightly contacts the top sealing cover 21 of the urine storage assembly 2. Under the action of coil spring No. 2 312, the movable valve plate 37 of the gas flow control assembly 3 presses against the top wall of the second component movable chamber 33, and the second sealing ring 310 abuts against the top wall of the second component movable chamber 33, closing valve No. 2.

[0032] When the urine collection device collects urine, the No. 3 docking channel 36 of the gas flow control component 3 is connected to the pipeline of the air pump, the sealing plug 28 is pulled out from the female connector 27, the female connector 27 is connected to the catheter used in the urology laparoscopy, and the No. 1 valve is opened. Start the air pump, the gas in the movable chamber 33 of the second component is sucked away, and a negative pressure environment is formed in the movable chamber 33 of the second component. The movable valve plate 37 moves downward, and a gap is formed between the second sealing ring 310 and the top wall of the movable chamber 33 of the second component. The gas in the airbag accommodating chamber 112 is sucked away through the No. 1 gas flow hole 19, the negative pressure environment chamber 14, the No. 1 docking channel 18, the No. 2 gas flow hole 34, the gap formed between the second sealing ring 310 and the top wall of the movable chamber 33 of the second component, the gas flow groove 38, the second component movable chamber 33, and the No. 3 docking channel 36, so that a negative pressure environment is formed in the airbag accommodating chamber 112; the volume of the urine collection airbag 23 increases under the action of the negative pressure environment, so that a negative pressure environment is formed in the urine storage chamber 24, and urine enters the urine storage chamber 24 of the urine collection airbag 23 through the catheter, female connector 27, and catheter hose 26 used in urological laparoscopy.

[0033] Take samples from the urine collection device. After the urine collection is completed, close valve No. 1 of the urine storage component 2, connect the female connector 27 to the sampling port of the sampling tank, open valve No. 1, open valve No. 2 of the gas flow control component 3, pull the longitudinal pull rod 311 downward, and the external gas enters the airbag accommodating chamber 112 through the No. 4 docking channel, the second component active chamber 33, the gas flow groove 38, the gap formed between the second sealing ring 310 and the top wall of the second component active chamber 33, the No. 2 gas flow hole 34, the No. 1 docking channel 18, the negative pressure environment chamber 14, and the No. 1 gas flow hole 19. The airbag accommodating chamber 112 is no longer a negative pressure environment, the urine collection airbag 23 is elastically reset, and the volume of the urine collection airbag 23 becomes smaller. The urine in the airbag accommodating chamber 112 enters the sampling tank through the No. 2 docking channel 25, the catheter hose 26, the No. 1 valve, and the female connector 27 to complete the sampling work.

[0034] The urine storage assembly 2 is recovered, valve No. 2 is closed, the bolt fasteners at the upper connecting ear 22 and the lower connecting ear 13 are removed, the top sealing cover 21 is lifted upward, the urine collection airbag 23 is taken out from the airbag accommodating chamber 112, and the urine storage assembly 2 is placed at the collection location.

[0035] The urine collection device for laparoscopic urology surgery of the present invention utilizes a disposable urine storage assembly 2, which utilizes a structure and an air pump to collect urine in a negative pressure environment. After urine collection is completed, the elastic deformation characteristics of the urine collection airbag 23 are utilized to sample urine. After sampling is completed, the disposable urine storage assembly 2 is directly discarded, eliminating all structures that have come into contact with the urine and preventing urine from contaminating other structures. During the urine sampling process, there is no need to manually disassemble the sampling bag, thus preventing urine from contaminating other structures.

[0036] 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 of urine collection and urine sampling, and has a high degree of integration. After urine sampling is completed, only the disposable urine storage component 2 needs to be discarded, and other structures can continue to be used, which is low in cost.
