[0002] Biomedical engineering is an interdisciplinary subject that combines biology, medicine and engineering. It uses engineering principles and methods to solve scientific problems in the medical field, promote medical technology progress and health industry development. In the above-mentioned urology drainage device, the role of biomedical engineering is reflected in many aspects, such as considering the physiological structure and pathological characteristics of the urinary tract from the perspectives of biology and medicine to ensure that the device meets the needs of the human body; using engineering precision design to optimize the structure of the drainage device, such as anti-reflux valve, etc.; and using material engineering technology to develop suitable medical polymer materials to ensure the biocompatibility of the device.

[0003] A drainage device for urology is disclosed in Chinese patent No. CN214762487U. The drainage device for urology includes a drainage tube and a hospital bed. The drainage tube is movably connected to the hospital bed. The side of the hospital bed is fixedly connected with a fixing block. The drainage tube is provided with a protection mechanism. The protection mechanism includes a plurality of support rings. A limiting shell is arranged between the support ring and the wire. One side of the limiting shell is provided with a clamping block. One end of the clamping block is fixedly connected with a rotating shaft. One end of the rotating shaft is fixedly connected with a gear. The top and bottom of the inner wall of the limiting shell are provided with a sliding groove. Two groups of movable assemblies are slidably connected inside the sliding groove. The drainage device for urology can be bent and can prevent the drainage tube from being squeezed, causing the drainage tube to be blocked.

[0042] The working process and principle of the above embodiment are as follows:

[0043] The initial state is as follows: the spring 303 is in an unstretched state.

[0044] The working steps are as follows:

[0045] First, the guide head 101 and the silica gel drainage tube 201 are fixed by screwing through the silica gel connecting plate 102, then the guide head 101 is inserted into the bladder, so that the urine in the bladder enters the silica gel installation groove one 203 of the silica gel drainage tube 201 through the drainage hole 202 on the outer wall of the silica gel drainage tube 201, so that the urine is around the silica gel arc-shaped plate 205, then the urine around the silica gel arc-shaped plate 205 is filtered through the gauze 206 and enters the installation groove two 209 inside the silica gel arc-shaped plate 205, then the urine is adsorbed by the silica gel flow guide tube 212 inside the installation groove two 209, so that the urine adsorbed by the silica gel flow guide tube 212 enters the inside of the silica gel flow guide tube 212 through the flow guide hole 213, so that the urine in the silica gel flow guide tube 212 flows into the inside of the silica gel flow guide tube 301, so that the urine in the silica gel flow guide tube 301 moves to one side of the cylindrical box 302 under the action of its own gravity, when the amount of urine in the silica gel flow guide tube 301 gradually increases, the urine in the silica gel flow guide tube 301 pushes the baffle 304, so that the baffle 304 moves away from the silica gel flow guide tube 301, at the same time, the baffle 304 pulls the spring 303 to stretch, finally the urine in the silica gel flow guide tube 301 flows into the inside of the gathering groove 305 through the intermittent space between the baffle 304 and the silica gel flow guide tube 301, so that the urine in the gathering groove 305 enters the inside of the nozzle 308 through the hose 306, and then the urine is discharged through the nozzle 308.

[0046] The gauze 206 in the drainage mechanism 2 can preliminarily filter the urine, intercept sediments and impurities, cooperate with the annular drainage hole 202 on the silica gel drainage tube 201 and the flow guide hole 213 of the silica gel flow guide tube 212, realize multi-channel shunt, significantly reduce the probability of lumen blockage, ensure the patency of drainage, reduce the need for frequent pipeline flushing or replacement due to lumen blockage, not only reduce the work burden of medical staff, but also reduce the pain and discomfort that patients may suffer during the operation process. On the other hand, unobstructed drainage can effectively prevent urine from accumulating in the body, reduce the risk of complications such as urinary tract infection, provide a stable guarantee for the postoperative recovery or treatment of patients, and help to speed up the rehabilitation process of patients and improve the treatment effect.

[0047] Because the urine in the gathering groove 305 cannot be completely discharged, as the amount of urine in the bladder gradually decreases, the squeezing force of the urine on the baffle 304 also decreases, and then the baffle 304 is in contact with the silica gel flow guide tube 301 again under the action of the spring 303, so that the urine in the gathering groove 305 cannot enter the bladder through the silica gel flow guide tube 301, preventing the problem of backflow of urine.

[0048] When the amount of urine is reduced, the baffle 304 is automatically closed to the end port of the silica gel flow pipe 301 under the spring force of the spring 303 through the cooperation of the spring 303 and the baffle 304 through the discharge mechanism 3, the urine in the accumulation groove 305 is prevented from flowing back to the bladder, the risk of reverse infection is effectively reduced, and the use safety is improved.
