Description

Technical Field

[0001] The utility model relates to the field of medical devices, and more specifically, to a separable collector for urinary calculi. Background Art

[0002] Urinary calculi, also known as urolithiasis and urinary tract stones, are one of the most common urological diseases. With the progress of medical technology, there are various treatment methods. Among them, extracorporeal shock wave lithotripsy uses extracorporeal shock waves to transfer energy externally to break up urinary calculi, and then the calculi are discharged from the body along with urine. This lithotripsy does not require anesthesia or hospitalization. Generally, lying on the lithotripter for about half an hour can end the treatment. The calculi discharged through the urethra become crushed stones or particles. To understand the composition and formation factors of the calculi and facilitate subsequent stone prevention and treatment for patients, a collection device is needed to collect the calculi.

[0003] Chinese Patent Authorization Publication No.: CN215609703, a urinary calculus collector, includes a urine catheter, a urine storage cylinder, a filter cover, and an elastic pusher; both the upper and lower ends of the urine catheter are open ends. The upper port of the urine storage cylinder is provided with a threaded sleeve that is threadedly connected to the outer wall of the lower end of the urine catheter. The filter cover is hemispherical and is located inside the urine storage cylinder. An annular shoulder that overlaps on the upper port of the urine storage cylinder is provided on the outer periphery of its upper end cover opening. And the end face of the lower port of the urine catheter presses against the upper end face of the annular shoulder after the threaded connection with the threaded sleeve is in place. An O-ring is provided between the upper end face of the annular shoulder and the end face of the lower port of the urine catheter. The elastic pusher is arranged inside the urine storage cylinder and elastically abuts against the outer spherical surface of the filter cover. The utility model filters urine and filters and collects the calculi that are directly discharged from the body along with urine.

[0004] Currently, there is still a problem that the lid of an existing separable collector for urinary calculi is prone to being lost. Since the lid is threadedly connected to the urine catheter, when using the device, the lid needs to be rotated and removed and placed aside, which easily causes the lid to be lost.

[0030] Please refer to Figures 1-7 , a separable urinary calculus collector, which includes a urine storage cylinder 1 and a urine guide cylinder 2. A cylinder cover 3 is rotatably installed at the top of the urine guide cylinder 2. A third sliding groove 18 is opened inside the cylinder cover 3. A third spring 19 is fixedly installed inside the third sliding groove 18. One end of the third spring 19 is fixedly installed with a third sliding block 20. The third sliding block 20 is slidably connected to the inside of the third sliding groove 18. A slot 22 is opened at the top of the urine guide cylinder 2. One end of the third sliding block 20 is inserted into the inside of the slot 22 and is slidably connected to the inside thereof. One side of the third sliding block 20 is fixedly installed with a pressing block 21. The pressing block 21 is slidably connected to the inside of the third sliding groove 18. A conical filter cylinder 15 is fixedly installed inside the urine guide cylinder 2. A plurality of filter holes 16 are opened on the outer wall of the conical filter cylinder 15. Hold the pressing block 21 to move the third sliding block 20, rotate and open the cylinder cover 3. When the patient urinates, aim at the upper part of the urine guide cylinder 2, so that the urine enters its inside from the upper part of the urine guide cylinder 2, and then passes through the filter holes 16 of the conical filter cylinder 15 for filtration. The urine passes through the filter holes 16 and is stored in the inside of the urine storage cylinder 1, while the calculi discharged together with the urine remain in the conical filter cylinder 15.

[0031] Two fixing blocks 4 are fixedly installed on the outer wall of the urine storage cylinder 1. Two limiting grooves 5 are opened at the bottom of the urine guide cylinder 2. The two fixing blocks 4 are respectively inserted into the two limiting grooves 5 and are slidably connected to them. After inserting the two fixing blocks 4 into the two limiting grooves 5 respectively and rotating, the urine storage cylinder 1 and the urine guide cylinder 2 can be fixed, which is convenient and fast.

[0032] A sealing ring 17 is fixedly installed at the bottom of the conical filter cartridge 15. By installing the sealing ring 17, when the patient urinates, urine can be effectively prevented from flowing out through the gap between the urine storage cylinder 1 and the urine drainage cylinder 2.

[0033] First sliding grooves 6 are provided above the two limiting grooves 5 inside the urine drainage cylinder 2. First springs 7 are fixedly installed inside the two first sliding grooves 6. One end of each of the two first springs 7 is fixedly installed with a first sliding block 8. One end of each of the two first sliding blocks 8 is fixedly installed with an insertion block 10. One end of each of the two insertion blocks 10 is inserted into the inside of the two fixing blocks 4. The first sliding block 8 is pushed out by the first spring 7, so that the insertion block 10 is inserted into the inside of the fixing block 4 to limit the fixing block 4 and prevent the urine drainage cylinder 2 from being accidentally touched and released from the limit with the urine storage cylinder 1.

[0034] Sliding inclined grooves 9 are provided on both sides of the two first sliding blocks 8. Two U-shaped sliding plates 11 are slidably installed inside the urine drainage cylinder 2. Two inclined groove sliders 12 are fixedly installed on the inner walls of the two U-shaped sliding plates 11.

When it is necessary to rotate the urine storage cylinder 1, hold the two U-shaped sliding plates 11 on the outer wall of the urine drainage cylinder 2 and slide them, driving the two first sliding blocks 8 to move towards one end, so that the insertion block 10 moves out of the inside of the limiting groove 5 to release the limit.

[0035] Two fixing grooves 13 are provided on the outer wall of the urine drainage cylinder 2. Two second springs 14 are fixedly installed inside the two fixing grooves 13. One end of each two second springs 14 is fixedly connected with the inner wall of the U-shaped sliding plate 11. After releasing the U-shaped sliding plate 11, the second spring 14 will push out the U-shaped sliding plate 11 to move the first sliding block 8.

[0036] Working principle:

[0037] Hold the pressing block 21 to move the third sliding block 20 and rotate to open the cylinder cover 3. When the patient urinates, aim at the upper part of the urine drainage cylinder 2 so that the urine enters its inside from the upper part of the urine drainage cylinder 2, and then passes through the filter holes 16 of the conical filter cartridge 15 for filtration. The urine passes through the filter holes 16 and is stored in the inside of the urine storage cylinder 1, while the stones discharged together with the urine remain in the conical filter cartridge 15, thereby realizing the collection of stones. Hold the two U-shaped sliding plates 11 on the outer wall of the urine drainage cylinder 2 and slide them, driving the two first sliding blocks 8 to move towards one end, so that the insertion block 10 moves out of the inside of the limiting groove 5, rotate the urine drainage cylinder 2, release the limit between the urine storage cylinder 1 and the urine drainage cylinder 2, and then the urine drainage cylinder 2 can be separated from the urine storage cylinder 1 to take out the stones inside.

[0038] The above are only the preferred specific embodiments of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
