Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a device for filtering kidney stone fragments and urine. Background Art

[0002] Kidney stones are a common disease of the urinary system, which refers to the abnormal accumulation of crystal substances (such as calcium, oxalic acid, uric acid, cystine, etc.) in the kidneys. These crystal substances form hard small lumps in the kidneys, which may cause symptoms such as low back pain and hematuria. For medical and pathological research, it is necessary to collect the patient's stones and urine. Therefore, a device for filtering kidney stone stones and urine is needed to filter, separate and collect the kidney stone stones and urine.

[0003] Most of the existing devices for filtering kidney stone fragments and urine use a filter to filter the kidney stone fragments. The filtered kidney stone fragments remain on the filter, and the urine is directly discharged. Most of the filter nets are fixed in a sealed box for use, and there is no structure designed to clean the filter net in the box. After the filter net filters the patient's kidney stone fragments and urine, the urine is likely to remain on the filter net and the inner wall of the box. When the next patient uses it, the residual urine of the previous patient will stick to the kidney stone fragments and merge into the urine, thereby affecting the accuracy of subsequent kidney stone fragments and urine test results, and reducing the accuracy of medical testing and analysis. To this end, we propose a device for filtering kidney stone fragments and urine. Summary of the invention

Since the driving gear 234 is meshed and connected with the driven gear plate 235, and the liquid supply pipe 231 is rotatably connected to the right inner wall of the filter box 1 through the bearing 233, the liquid supply pipe 231 can rotate, and the multiple groups of nozzles 232 can rotate, so as to realize the backwashing of the filter screen 24 and the all-round washing of the inner wall of the filter box 1, so as to avoid the urine of the previous patient remaining on the filter screen 24, improve the accuracy of the subsequent kidney stone crushing and urine test results, and improve the accuracy of medical detection and analysis; Among them, when the kidney stone crushing collection box 9 needs to be installed in the inner cavity of the sealed box 8, the staff holds the pull ring 29 to drive the movable rod 28 on the disassembly unit to move outward, and the auxiliary slide plate 30 moves outward at this time, the compression spring 31 is in a compressed state, and the positioning block 32 is stored in the inner cavity of the U-shaped seat 22. At this time, the inner cavity of the sealed box 8 is not restricted, and then the kidney stone crushing collection box 9 can be smoothly slid into the sealed box 8. After the kidney stone crushing collection box 9 is installed in the right position, the positioning groove 27 on the kidney stone crushing collection box 9 is aligned with the through hole 26, and then the movable rod 28 is released, and the compressed compression spring 31 can be automatically After returning to its original position, the auxiliary slide plate 30 moves toward one side of the through hole 26, and the positioning block 32 passes through the through hole 26 and is connected to the positioning groove 27, thereby fixing the position of the kidney stone crushing collection box 9. When the kidney stone crushing collection box 9 needs to be taken out, the movable rod 28 is pulled outward to drive the positioning block 32 to disengage from the positioning groove 27, and the position of the kidney stone crushing collection box 9 is no longer restricted and can be quickly slid out of the inner cavity of the sealing box 8, wherein the anti-slip rubber sleeve on the outer wall of the pull ring 29 plays an anti-slip role to prevent the hand from slipping when holding the pull ring 29, and a handle is provided on the outer wall of the kidney stone crushing collection box 9, and the handle facilitates the removal and installation of the kidney stone crushing collection box 9.

[0026] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
