Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical equipment technology, and in particular to a kidney stone filter collector. Background Technology
[0002] Kidney stones are a condition caused by the crystallization and accumulation of minerals in the urine within the kidneys, forming hard lumps. The main symptoms include lower back pain, hematuria (blood in the urine), and stinging pain during urination. Treatment options for kidney stones are diverse, including medication, surgical procedures such as extracorporeal shock wave lithotripsy (ESWL), percutaneous nephrolithotomy (PCNL), ureteroscopic lithotripsy, and open surgery. Traditional Chinese medicine and litholytic therapies are also available. ESWL often utilizes ultrasonic vibrations. After minimally invasive surgery or ESWL, fragmented stone samples are collected for pathological analysis to determine the type of stone—calcium-containing, infectious, uric acid, or cystine—to facilitate targeted treatment.
[0003] A search revealed Chinese Patent Publication No. CN117679828A, which discloses a kidney stone filtration and collection device. The device includes a collector, a filter screen, and a collection tube connected to the collector. It also includes a connecting shaft rotatably connected to the collector, with a frame fixedly fitted onto the shaft. The filter screen is fixedly mounted on the frame. Furthermore, it includes a negative pressure bulb with an inlet and an outlet. The inlet is connected to the collector below the filter screen, while the outlet is above the filter screen and faces it. Flushing fluid introduces the stones and urine into the collection tube, where they fall onto the filter screen for filtration. The stones are filtered onto the filter screen. By squeezing the negative pressure bulb, the filtered flushing fluid is drawn in and used to flush the stones on the filter screen through the outlet of the negative pressure bulb.
[0004] However, once the stones are filtered through the filter, they are not easy to remove from the collector. Utility Model Content

[0026] like Figures 1-5As shown, a kidney stone filter collector includes a processing tank 1. A collection tube 101 is detachably connected to the top of the processing tank 1. A flushing solution introduces the stones and urine into the collection tube 101. A filter plate 102 is fixedly connected between the inner walls of the processing tank 1. A flushing mechanism is provided above the filter plate 102. The flushing mechanism includes an inlet pipe 501 fixedly connected to the top of the processing tank 1. Water is pumped into the inlet pipe 501 by an external water pump. A rotating pipe 502 is rotatably connected to the inner top wall of the processing tank 1. The inlet pipe 501 communicates with the rotating pipe 502. A horizontal pipe 503 is fixedly connected to the side wall of the rotating pipe 502. A plurality of equally spaced nozzles 504 are fixedly connected to the bottom of the horizontal pipe 503.
[0027] The rinsing mechanism also includes a rotating assembly, which drives the rotating tube 502 to rotate. The rotating assembly includes a gear ring 505 fixedly connected to the outer wall of the rotating tube 502. A stepper motor 506 is bolted to the top of the treatment box 1. A gear 507 is fixedly connected to the output shaft of the stepper motor 506. The gear 507 meshes with the gear ring 505. When the stepper motor 506 is started, the stepper motor 506 drives the gear 507 to rotate within a certain angle. The gear 507 meshes with the gear ring 505, thereby driving the gear ring 505 to drive the rotating tube 502 and the horizontal tube 503 to rotate within a certain angle, which facilitates the thorough rinsing of the stones on the filter plate 102.
[0028] A drain pipe 103 is fixedly connected to the bottom of the side wall of the treatment box 1. A control valve is installed inside the drain pipe 103. The inner bottom wall of the treatment box 1 is inclined. The drain pipe 103 is located on the lower side of the inner bottom wall of the treatment box 1. The filter plate 102 is inclined. A discharge port 104 is opened on the side wall of the treatment box 1. The discharge port 104 is located on the lower side of the filter plate 102. A sealing assembly is installed at the discharge port 104. The sealing assembly includes a hydraulic cylinder 201 fixedly connected to the top wall of the treatment box 1. A baffle 202 is fixedly connected to the bottom of the hydraulic cylinder 201. The baffle 202 is in close contact with the inner wall of the treatment box 1.
[0029] A striking mechanism is provided below the filter plate 102. The striking mechanism includes multiple sets of rotating shafts 401 rotatably connected between the inner walls of the processing box 1. Multiple sets of circumferentially arranged elastic ropes 402 are fixedly connected to the rotating shafts 401. The ends of the elastic ropes 402 are fixedly connected to striking balls 403. The striking mechanism also includes a power component for driving the rotating shafts 401 to rotate. The power component includes a rotary motor 404 fixedly connected to the outer wall of the processing box 1. The output end of the rotary motor 404 is connected to one of the rotating shafts 401 through a coupling. The ends of the rotating shafts 401 extend out of the processing box 1, and a belt 405 is connected between adjacent rotating shafts 401 through pulleys.
[0030] A support frame 301 is fixedly connected to the side wall of the processing box 1. A collection box 302 is placed above the support frame 301, and the discharge port 104 is located above the collection box 302.
[0031] Working principle: The flushing fluid introduces the stones and urine into the collection pipe 101, and then falls onto the filter plate 102 for filtration. The stones are filtered onto the filter plate 102, while the liquid flows through the filter plate 102 to the bottom of the treatment tank 1. After the stones are drained, an external water source is pumped through the inlet pipe 501 to the rotating pipe 502, and then through the rotating pipe 502 to the horizontal pipe 503. Finally, the water is sprayed onto the filter plate 102 through several nozzles 504 to flush the stones on the filter plate 102. At the same time, the stepper motor 506 is started, which drives the gear 507 to rotate within a certain angle. The gear 507 meshes with the gear ring 505, thereby driving the gear ring 505 to rotate the rotating pipe 502 and the horizontal pipe 503 within a certain angle, facilitating the rotation of the filter plate 102. The stones on the filter plate 102 are thoroughly rinsed. After rinsing, the baffle 202 is moved upward by the hydraulic cylinder 201, opening the discharge port 104. The rotary motor 404 is started, driving one of the rotating shafts 401 to rotate. Through the transmission between the pulley and the belt 405, the other rotating shafts 401 are driven to rotate. The rotating shafts 401 drive the elastic rope 402 to drive the striking ball 403 to rotate. The striking ball 403 intermittently strikes the filter plate 102 from bottom to top, causing the stones on the filter plate 102 to fall into the collection box 302 through the discharge port 104, thus facilitating the collection of the filtered stones. Then, the liquid at the bottom of the treatment tank 1 is discharged through the drain pipe 103, and clean water is sprayed out through the nozzle 504 to rinse the inside of the treatment tank 1.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
