Description

Technical Field

[0001] This utility model relates to the field of assistive devices for patients with kidney stones, and in particular to a kidney stone filter. Background Technology

[0002] Urinary tract stones are a common disease in urology. With the advancement of technology, flexible urethral surgery can break up stones in the bladder or kidneys and allow them to be expelled through the urethra with urine. However, the expelled stones need to be collected, and in some patients, pathological analysis of the stones is required. The collected stones also need to be accurately weighed to determine the effectiveness of flexible urethral stone removal and to provide a basis for further treatment. Clinically, to obtain the broken stones expelled from the patient's urethra, the patient is usually asked to urinate into a funnel and drain the urine. This allows for the collection of some stone particles for pathological separation. However, when it is necessary to obtain all the broken stones in the excreted urine, in clinical practice, the urine is first collected in a urine collection bag, and then poured into a urine collection pot with a filter to obtain all the stones from the single urination. However, whether it is the patient or their family member performing the urine collection and stone filtering procedure, the smell of the urine always creates a certain emotional state, making it difficult to effectively collect the patient's excreted urine in practice, which can interfere with the patient's subsequent treatment.

[0016] Reference Figures 1 to 11 The structural features of this stone filter are described in detail below: A stone filter, comprising 100 open urine collection trays are used for collecting urine from patients. The urine collection transfer box 200 is connected to the inlet of the urine collection open plate 100. A filter box 300 is disposed at the connection position between the outlet of the urine collection open tray 100 and the inlet of the urine collection transfer box 200. A rotary drive mechanism drives the filter box 300 to rotate with the rotation axis vertical.

[0017] The filter includes an open urine collection tray 100, a urine transfer box 200, a filter box 300, and a rotation drive mechanism. The patient urinates onto the open urine collection tray 100, and the urine flows through the tray into the transfer box 200. The filter box 300 filters the urine, and by activating the rotation drive mechanism, the filter box 300 rotates rapidly, quickly separating the urine from the fine stones. Removing the filter box 300 allows for the collection of most of the stones from a single urination, providing a more accurate basis for subsequent pathological analysis and treatment.

[0018] The urine transfer box 200 serves as a transfer point for urine. It is equipped with a tube or other opening for rapid discharge. When the patient urinates, the urine is quickly discharged into the toilet or other urine collection container through the urine transfer box 200.

[0019] As a preferred embodiment of this utility model, the filter box 300 is rotatably disposed inside the urine transfer box 200, and the rotation drive mechanism drives the filter box 300 to rotate.

[0020] Because the stones pulverized through flexible urethral surgery are small in size, the mesh density of the filter box 300 is very small. Small stones can easily clog the mesh, causing problems with urination. To address this, the filter box 300 is rotated by activating a rotating drive mechanism, which acts as a centrifuge, allowing urine to pass through the filter box 300 quickly and preventing clogging and other problems with urination.

[0021] Preferably, the opening of the filter box 300 and the opening of the urine transfer box 200 are connected by an insertion, and the rotary drive mechanism and the bottom of the filter box 300 are connected by both insertion and separation.

[0024] The urine collection tray 100 is oval in shape, making it convenient for both male and female patients to use. The urine discharged by the patient is discharged through the discharge ramp 110 onto the receiving surface 120. The urine then enters the urine transfer box 200 through the urination port 121 and is filtered by the filter box 300 to remove stones from the urine. When the urine collection tray 100 and the urine transfer box 200 are combined, the insertion tube 130 and the opening of the urine transfer box 200 form an insertion and separation fit, which facilitates the disassembly of the urine collection tray 100 and the urine transfer box 200 and the removal of the filter box 300 to obtain the crushed stones in a single urination.

[0025] The urine collection transfer box 200 is generally cylindrical. The insertion tube 130 is inserted into the outer wall of the opening of the urine collection transfer box 200.
