Description

Technical Field

[0001] The embodiments of the present invention belong to the field of Oncomelania hupensis crushing, and more specifically, relate to an anti-interference, self-cleaning Oncomelania hupensis crushing device for microscopic examination and its usage method. Background Technology

[0002] Oncomelania hupensis, the only intermediate host of Schistosoma japonicum in Hubei Province, plays a crucial role in the prevalence and transmission of schistosomiasis. Controlling and eliminating Oncomelania hupensis is one of the key measures to block and eliminate schistosomiasis. To understand the distribution of Oncomelania hupensis in schistosomiasis-endemic areas, surveys on snail density and infection status are conducted annually in spring and autumn to enable precise drug control of snails. Furthermore, the "Oncomelania hupensis Survey" (WS / T 563—2017) and the "National Schistosomiasis Monitoring Program" (2020 edition) require the use of crushing microscopy to identify the liveness and infectivity of Oncomelania hupensis. Based on this, a tool device for easy crushing microscopy of Oncomelania hupensis is proposed, which is of great significance for promoting the elimination of schistosomiasis.

[0003] To address the technical challenge of efficiently crushing Oncomelania snails, Chinese invention patent CN203203856U discloses an Oncomelania snail crusher, which consists of a base, a pressure rod, an upper pressure plate, and a lower pressure plate. The left end of the pressure rod is hinged to one end of the base. The lower pressure plate is fixed to the middle of the base via a lower pressure plate fixing rod, and the upper pressure plate is fixed to the middle of the pressure rod via an upper pressure plate fixing rod. A reinforcing rib is installed between the upper pressure plate and the upper pressure plate fixing rod. A handle ball is installed at the right end of the pressure rod. Furthermore, Chinese invention patent CN205449619U discloses a snail crusher, including an L-shaped support, an upper pressure plate, and a lower pressure plate. The L-shaped support is connected to one end of a pressure rod, and the middle part of the pressure rod is connected to one end of the pressure rod. One side of the L-shaped support is connected to a fixed sleeve via a bracket. A sliding plate is provided on the pressure rod, and the sliding plate is located inside the fixed sleeve. A return spring is provided between the lower side of the sliding plate and the fixed sleeve. The lower pressure plate has a U-shaped structure, and its lower end is placed on a support block via a fixed shaft. After the crushing process is completed, the pressure rod of this invention moves the sliding plate upward along the fixed sleeve under the action of the return spring, thus returning the upper pressure plate to its original position, making operation convenient. By setting the lower pressure plate to a U-shaped structure, the snails can be prevented from splashing during crushing, protecting the workers. By providing a fixed shaft at the lower end of the lower pressure plate, the lower pressure plate can be directly removed for cleaning after the snails are crushed, making operation convenient.

[0004] The above-mentioned patented technologies effectively solve the technical problems of splashing and positioning of Oncomelania snails during crushing, but there are still the following defects or areas for improvement: (1) When dealing with a large number of Oncomelania snail microscopic examinations, the manual crushing method will inevitably cause uneven stress on the snail body and different crushing degrees, which will affect the quality of subsequent microscopic examinations. Therefore, the crushing process of large batches of Oncomelania snails can be optimized from the perspective of automated crushing methods; (2) In the prior art, after the Oncomelania snails are crushed, the pressing plate needs to be cleaned separately, which generates extra labor. Therefore, the Oncomelania snail pressing plate cleaning device can be integrated into the system to improve the overall work efficiency; (3) During the process of crushing and microscopic examination of a large number of Oncomelania snails at the same time, there is a problem that they are not easy to arrange neatly. At the same time, the body fluids of adjacent Oncomelania snails after crushing are easily cross-contaminated. The above-mentioned patented methods have effectively solved this problem.

[0064] The structure includes a drive mounting cavity 2244 vertically formed inside the supporting main body block 200; a push drive motor 2241 fixedly mounted at the bottom of the drive mounting cavity 2244; a push drive screw 2243 coaxially and fixedly connected to the output shaft of the push drive motor 2241; and a vertical transmission nut 2242 that maintains linear thread transmission with the push drive screw 2243.

[0065] The working principle of this invention embodiment is as follows: the push drive motor 2241 is controlled to rotate, thereby driving the vertical transmission nut to move vertically upward along the push drive screw, which in turn drives the push connecting rod 223 to move upward with the vertical transmission nut 2242, thereby causing the bottom of the screw plate 221 to move upward.

Screws are then placed in the screw placement groove 500 of the screw plate mounting groove 302. Next, the vertical drive component 210 is activated, and the supporting main block 200 is controlled to move upward. After reaching a certain height, the pressure plate flattening component is activated to flatten the screw pressure plate. Next, the vertical drive component 210 is controlled again to make the supporting main block 200 move downward, driving the screw pressure plate to apply pressure to the screws. When it descends to a preset position, the downward pressure stops. Next, the screw pressure plate is retracted and the supporting main block 200 is retracted downward in sequence. Next, the pressure plate cleaning unit 4 is activated to rinse the surface of the screw pressure plate with water, thereby achieving self-cleaning. Finally, the operator removes the screw placement plate 5, completing one pressing operation.

[0081] S201: Control the rotation of the push drive motor 2241, thereby driving the vertical transmission nut to move vertically upward along the push drive screw, which in turn drives the push connecting rod 223 to move upward with the vertical transmission nut 2242, thereby causing the bottom of the screw plate 221 to move upward.
