Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a stone collection device with a flushing function. Background Art

[0002] Urinary stones are one of the common diseases in urology, and they rank first among the inpatients in urology. With the emergence of treatments such as extracorporeal shock wave lithotripsy, percutaneous nephrolithotomy, and ureteroscopic lithotripsy, the treatment of urinary stones has gradually developed in a minimally invasive direction, achieving better treatment results. In recent years, the incidence of urinary stones has been on the rise worldwide, and the recurrence rate in 5-10 years can be as high as over 50%. Therefore, the prevention of urinary stones is very important. Currently, the main measures to prevent urinary stones include: drinking more water, exercising more, adjusting diet and using drugs to dissolve stones. Dietary adjustment and drug dissolution need to be adjusted according to the analysis of stone composition.

[0003] The Chinese Patent Network discloses a "disposable separated stone collector" with a publication number of CN219579501U. The device comprises, from top to bottom, a funnel (1), a stone filtering and collecting cup (2), and a urinal (3). The bottom opening of the funnel (1) is arranged at the top opening position of the stone filtering and collecting cup (2), the bottom opening of the stone filtering and collecting cup (2) is arranged at the opening position of the urinal (3), and the stone filtering and collecting cup (2) is provided with a filtering device (8) which blocks the top opening and the bottom opening of the stone filtering and collecting cup (2). By connecting the funnel, the stone filtering and collecting cup, and the urinal into a whole, the stones in the patient's urine can be filtered and collected. The entire stone collection process does not require contact with urine, thereby avoiding urine contamination of patients and medical staff. The operation is convenient, and the stone collection rate is greatly improved.

[0004] During use, it was found that since the stones in the urine needed to be filtered and collected, urine was attached to the surface of the stones. The collected stones needed to be rinsed with clean water before they could be used for stone composition analysis. The second flushing of the collected stones increased the difficulty of operation for medical staff. Utility Model Content

[0035] In this embodiment, the funnel 100, the connecting pipe 200 and the liquid storage pot 300 can be connected in sequence in advance. In this application, the connection between the catheter 102, the connecting pipe 200 and the liquid storage pot 300 is preferably a threaded connection, but the connection between the catheter 102, the connecting pipe 200 and the liquid storage pot 300 includes but is not limited to the above-mentioned connection structure; urine is urinated into the leakage nozzle 101, and then the urine will flow through the catheter 102 and the connecting pipe 200 to the liquid storage pot 300 in sequence. During the circulation in the connecting pipe 200, the urine will filter the stones in the urine through the filter assembly. When flushing is required, the rotating plate 105 is first rotated to drive the rotation, and then the rotation state of the baffle 104 is changed to block the catheter 102. When the rotating rod 103 is rotated to an appropriate After the angle is reached, it is fixed under the elastic force of the rubber pad 106, and then the flushing tube 205 is placed at one end outside the connecting tube 200 to connect to the flushing device. The flushing device will flow clean water through the flushing tube 205, the cavity 202 and the flushing hole 203 in sequence, and the clean water will flush upward to flush the stones on the filter component, and the flushed liquid will pass through the outflow hole 204 and flow into the liquid storage pot 300; the other flushing methods are as follows: clean water flows through the leakage nozzle 101, the conduit 102, and the connecting tube 200 into the liquid storage pot 300 in sequence, and the clean water will pass through the filter screen 207 during the circulation process in the connecting tube 200, thereby flushing the stones on the filter screen 207. During this process, the flushing tube 205 needs to be blocked by the valve 400 to prevent the flushing liquid from flowing out.

[0036] The connection relationship, specific structure and working principle between the flushing pipe 205 and the flushing device adopt the existing technology in this field, and this application will not repeat them here. The flushing device can be controlled manually or automatically, which falls within the scope of protection of this application.

[0037] See also Figure 2 In some embodiments, the filter assembly includes a fixing ring 206 and a filter screen 207. The surface of the fixing ring 206 abuts against the inner wall of the connecting tube 200. The filter screen 207 is arranged on the inner wall of the fixing ring 206. There are multiple filter assemblies, and the multiple filter assemblies are stacked from top to bottom. The apertures of the multi-layer filter screens 207 decrease from top to bottom.

[0038] In this embodiment, the filter 207 comes into contact with the urine as it flows through the connecting tube 200, and the filter 207 can filter the stones. The aperture of the filter 207 decreases from top to bottom, and stones of different sizes can be filtered in different grades to facilitate subsequent stone composition analysis.

[0039] See also Figure 1 and Figure 2 In some embodiments, a drain pipe 301 is provided on the surface of the liquid storage pot 300, a valve 400 is provided on the surface of the drain pipe 301 and located outside the liquid storage pot 300, a valve 400 is provided on the surface of the flushing pipe 205 and located outside the connecting pipe 200, a handle 302 is provided on the surface of the liquid storage pot 300, the connecting pipe 200 and the fixing ring 206 are both made of transparent material, and a scale line 303 is provided on the surface of the liquid storage pot 300.

[0040] In this embodiment, the valve 400 on the drainage pipe 301 can be rotated to facilitate the discharge of the liquid in the liquid storage pot 300 through the drainage pipe 301. At the same time, the flushing pipe 205 can be blocked by the valve 400 on the flushing pipe 205 to prevent the urine in the flushing pipe 205 from flowing out. The handle 302 is provided for easy removal of the liquid storage pot 300. The scale line 303 provided on the liquid storage pot 300 can be used to know the amount of liquid in the liquid storage pot 300, which is mainly used to know the amount of urine in the liquid storage pot 300. The transparent material of the connecting pipe 200 and the fixing ring 206 makes it easy to know the stone filtration situation on the filter screen 207, which is convenient for direct observation by patients and medical staff.

[0041] Specifically, the working principle of the stone collection device with flushing function provided by this application is:

[0042] The funnel 100, the connecting pipe 200, and the liquid storage pot 300 can be connected in sequence in advance. At this time, the valves 400 on the flushing pipe 205 and the drainage pipe 301 are both blocked, and urine is urinated into the leakage nozzle 101. Then, the urine will flow through the catheter 102 and the connecting pipe 200 to the liquid storage pot 300. During the flow of urine in the connecting pipe 200, the filter 207 will come into contact with the urine. At the same time, the filter 207 can filter the stones. The aperture of the filter 207 decreases from top to bottom, and stones of different sizes can be filtered in a graded manner to facilitate subsequent stone composition analysis.

[0043] When flushing is needed, first rotate the rotating plate 105 to drive the rotation, and then change the rotation state of the baffle 104 to block the catheter 102. When the rotating rod 103 is rotated to an appropriate angle, it is fixed by the elastic force of the rubber pad 106. Then, the flushing pipe 205 is placed at one end outside the connecting pipe 200 and connected to the flushing device. The valve 400 on the flushing pipe 205 is opened to put the flushing pipe 205 in a flow state. The flushing device is started to let clean water flow through the flushing pipe 205, the cavity 202 and the flushing hole 203 in turn. The clean water flushes upward to flush the stones on the filter component. The flushed liquid will pass through the outflow hole 204 and flow into the liquid storage pot 300.
