[0007] Furthermore, the middle cylinder includes an outer cylinder II and an inner cylinder II. The inner cylinder II is located inside the outer cylinder II. A connecting rod is provided between the inner cylinder II and the outer cylinder II. An annular boss is provided on the inner wall of the inner cylinder II. A handle is symmetrically provided on the side wall of the outer cylinder II. A retaining edge is provided at the bottom of the side wall of the outer cylinder II. A retaining groove is provided at the top of the side wall of the outer cylinder II.

[0008] Furthermore, the upper cylinder includes an outer cylinder three and an inner cylinder three. The inner cylinder three is located inside the outer cylinder three. The top of the side wall of the inner cylinder three is provided with an opening two. The side wall of the outer cylinder three is provided with a retaining edge two. The top of the outer cylinder three is provided with a handle two.

[0009] Furthermore, the inner cylinder one and the outer cylinder one have openings at the top, the inner cylinder two and the outer cylinder two have openings at the top and bottom, the inner cylinder three and the outer cylinder three have openings at the bottom, the inner cylinder one, the inner cylinder two and the inner cylinder three have the same radius, the outer cylinder one, the outer cylinder two and the outer cylinder three have the same radius, the retaining edge one is inserted into the retaining groove one, the retaining edge two is inserted into the retaining groove two, the gap between the outer cylinder one and the inner cylinder one, the gap between the outer cylinder two and the inner cylinder two, and the gap between the outer cylinder three and the inner cylinder three form a passage, and the passage communicates with the inner cylinder one, the inner cylinder two and the inner cylinder three through the through-hole one and the through-hole two.

[0010] Furthermore, the placement tray includes an outer ring, an inner ring, and a hollow support. The inner ring is located inside the outer ring, and the hollow support is located inside the inner ring. A blade is arranged in a circumferential array between the outer ring and the inner ring. A retaining edge is provided on the outer side of the outer ring, and the retaining edge is slidably disposed in a groove.

[0011] Furthermore, the filter plates are respectively disposed above the annular boss and inside the arc groove. The filter plate includes a ring and a filter cloth, with the filter cloth disposed inside the ring.

[0012] The beneficial effects of the present invention using the above structure are as follows: The surgical instrument cleaning quality testing device provided by this solution allows for the detection of surgical instrument cleaning quality after the surgical instruments are placed on the hollow support of the placement tray, the middle cylinder, filter plate, and upper cylinder are installed sequentially, and the valve is closed. First, the impeller is started, and during rotation, it delivers air downwards from the cylinder. Driven by the impeller, the air circulates through inlets one and two between the inner cylinders one, two, and three and the passageway, thereby blowing off fine impurities such as dust and lint adhering to the surgical instruments. These impurities then adhere to the filter plate located on the annular protrusion under the action of airflow circulation. During this process, the airflow pushes the blades of the placement tray, causing the tray to rotate. As the tray rotates, a lever above the tray moves the surgical instruments on the tray, causing them to flip, thus cleaning each individual surgical instrument. The surface is evenly blown by the airflow, making the detection more thorough. After detecting fine impurities such as floating dust and lint, the washing solution is injected into the lower cylinder through the connecting pipe. After injection, the impeller is restarted and its speed is reduced, and it is circulated in both directions to stir the liquid in the cylinder and wash the surgical instruments. This removes viscous impurities such as dried body tissue and coagulated body fluid from the surgical instruments. After cleaning, the valve can be opened to allow the washing solution to pass through the filter plate on the arc groove and be discharged. The viscous impurities are then attached to the filter plate, completing the detection. Compared with the traditional method, this solution can detect two types of impurities separately and collect them through the filter plate, making the cleaning quality more intuitive. The operator only needs to observe the impurities on the two filter plates. Compared with the traditional method, the detection of the cleaning quality of surgical instruments is more comprehensive and can effectively improve the cleaning quality of surgical instruments.

A retaining groove 207 is provided at the top of the side wall of the outer cylinder 201.

[0021] Furthermore, the upper cylinder 3 includes an outer cylinder 301 and an inner cylinder 302. The inner cylinder 302 is located inside the outer cylinder 301. The top of the side wall of the inner cylinder 302 is provided with an opening 304. The side wall of the outer cylinder 301 is provided with a retaining edge 303. The top of the outer cylinder 301 is provided with a handle 305.

[0022] Furthermore, the inner cylinder 103 and the outer cylinder 101 are open at the top, the inner cylinder 202 and the outer cylinder 201 are open at the top and bottom, and the inner cylinder 302 and the outer cylinder 301 are open at the bottom. The inner cylinder 103, the inner cylinder 202 and the inner cylinder 302 have the same radius, and the outer cylinder 101, the outer cylinder 201 and the outer cylinder 301 have the same radius. The retaining edge 1 206 is inserted into the retaining groove 102, and the retaining edge 2 303 is inserted into the retaining groove 207. The gap between the outer cylinder 101 and the inner cylinder 103, the gap between the outer cylinder 201 and the inner cylinder 202, and the gap between the outer cylinder 301 and the inner cylinder 302 form a passage 6. The passage 6 communicates with the inner cylinder 103, the inner cylinder 202 and the inner cylinder 302 through the through port 105 and the through port 2 304.

[0023] Furthermore, the placement tray 4 includes an outer ring 401, an inner ring 402, and a hollow support 404. The inner ring 402 is located inside the outer ring 401, and the hollow support 404 is located inside the inner ring 402. A blade 403 is arranged in a circumferential array between the outer ring 401 and the inner ring 402. A retaining edge 405 is provided on the outer side of the outer ring 401, and the retaining edge 405 is slidably disposed in the groove 104.

[0024] Furthermore, the filter plates 5 are respectively disposed above the annular boss 204 and inside the arc groove 112. The filter plates 5 include an annular ring 501 and a filter cloth 502, with the filter cloth 502 disposed inside the annular ring 501.

[0025] In practical use, first place the surgical instruments on the hollowed-out bracket 404 of the placement tray 4, then align the first clamping edge 206 with the first clamping groove 102 to install the middle cylinder 2, then place the filter plates 5 on the annular boss 204 and in the arc groove 112 respectively, then align the second clamping edge 303 with the second clamping groove 207 to install the upper cylinder 3, and close the valve 111. After completing the preparation work, the cleaning quality of the surgical instruments can be tested. At the beginning, first start the impeller 108. The impeller 108 rotates at high speed. During rotation, air is conveyed downwards from the cylinder. Driven by the impeller 108, the air circulates through the inlet 105 and inlet 204 between the inner cylinder 103, inner cylinder 202, and inner cylinder 302 and the passage 6, thereby blowing off fine impurities such as dust and lint adhering to the surgical instruments. Under the action of airflow circulation, these impurities adhere to the filter plate 5 located on the annular boss 204. During this process, the airflow pushes the blades 403 of the placement tray 4, thereby causing the placement tray 4 to rotate (due to the blades...). Because the plates 403 are small in size and few in number, the rotation speed of the placement tray 4 is relatively slow, preventing surgical instruments from being flung out during rotation. While the placement tray 4 rotates, the lever 107 above it moves the surgical instruments, causing them to flip. This ensures that all surfaces of the surgical instruments are evenly airflowed, resulting in more thorough testing. After detecting fine impurities such as dust and lint, the impeller 108 is turned off, and washing solution is injected into the lower cylinder 1 through the connecting pipe 106. After injection, the impeller 108 is restarted and its rotation speed reduced. Simultaneously, the impeller 108 is controlled to circulate in both directions, stirring the liquid in the cylinder and washing the surgical instruments. This removes viscous impurities such as dried body tissue and coagulated bodily fluids from the surgical instruments. After cleaning, the valve 111 is opened, allowing the washing solution to pass through the filter plate 5 on the arc groove 112 and be discharged. The viscous impurities adhere to the filter plate 5. After testing, the cleaning quality of the surgical instruments can be directly observed by simply looking at the number of impurities on the two filter plates 5.
