[0002] The Medical Function Experiment Center is the most basic experimental center in the School of Basic Medical Sciences. The medical function experiment course offered by the center is a compulsory course for almost all medical students. In the teaching of basic medical function experiments, multiple groups of students usually conduct experiments at the same time. In order to complete the experiments, each group of students has several kinds of functional experimental surgical instruments. During the experiment, surgical instruments may be handled in a disorderly manner or even lost. Therefore, it is necessary to store and distribute the instruments in a unified manner to avoid management chaos and instrument loss.

The fan box 304 is connected and fixed to the fan mounting base 303 by screws. One end of the power socket 302 passes through the ventilation mounting plate 301 and is connected to the sterilization lamp 306 by threads. The ventilation sleeve 305 is connected to the second sealing plate 504 by threads. By fitting the ventilation sleeve 305 onto the outside of the sterilization lamp 306, it is convenient for the ventilation sleeve 305 to perform sterilization operation on the airflow through the sterilization lamp 306 during the ventilation process, ensuring that the air introduced remains clean.

[0033] The conveyor belt 501 is connected to both sides of the first sealing plate 204 and the second sealing plate 504 via belt retaining rings 508. The conveyor belt 501 is connected to the connecting rod 503 via a transmission roller 502. One end of the connecting rod 503 passes through the second sealing plate 504 and is connected to the transmission roller 502 via a flat key. The transmission motor 505 is welded and fixed to one end of the second sealing plate 504. The rotating positioning strip 506 and the elastic support strip 507 are both connected and fixed to the conveyor belt 501 via screws. The conveyor belt 501 is connected to the placement box 401 via the rotating positioning strip 506 and the elastic support strip 507, so that the transmission motor 505 drives the conveyor belt 501 to rotate via the connecting rod 503 and the transmission roller 502, thereby facilitating the adjustment of the position of the eight instrument installation boxes 4.

[0034] By adopting the above technical solution, belt retaining rings 508 are fixedly installed on one side of the first sealing plate 204 and the second sealing plate 504, so that both ends of the conveyor belt 501 are positioned and installed with the first sealing plate 204 and the second sealing plate 504 through the belt retaining rings 508. The conveyor belt 501 is connected to the eight instrument mounting boxes 4 through the rotating positioning strip 506 and the elastic support strip 507. When the power is turned on, one end of the connecting rod 503 passes through the second sealing plate 504 and is connected to the transmission roller 502 through the flat key. A positioning plate 404 is installed on the inner side of the box body 401, so that the instrument clamping plate 402 and the connecting strip 405 can be positioned and installed through the positioning plate 404.

[0035] In summary, when using the device, check the functionality of each component. Belt retaining rings 508 are fixedly installed on one side of both the first sealing plate 204 and the second sealing plate 504, ensuring that both ends of the conveyor belt 501 are positioned and installed with the first sealing plate 204 and the second sealing plate 504 via the belt retaining rings 508. The conveyor belt 501 is connected to the eight instrument mounting boxes 4 via rotating positioning bars 506 and elastic support bars 507. Power is turned on, and one end of the connecting rod 503 passes through the second sealing plate 504 and is connected to the transmission roller 502 via a flat key. A positioning plate 404 is installed inside the box 401, facilitating the positioning and installation of the instrument clamping plate 402 and the connecting bar 405. Instruments are placed inside each pair of adjacent instrument clamping plates 402, allowing the elastic retaining bars 403 to hold and seal each pair of adjacent instrument clamping plates 402, improving the stability and cleanliness of instrument placement. Before distributing the instruments, the drive motor 505 is started. The drive motor 505, supported by the second sealing plate 504, drives the drive roller 502 to rotate via one of the connecting rods 503. The drive roller 502 then drives the conveyor belt 501 to rotate inside the belt retaining ring 508, which facilitates the adjustment of the position of the eight instrument mounting boxes 4. The eight instrument mounting boxes 4 facilitate the storage and placement of different types of instruments. The upper end of one of the placement boxes 401 contacts the take-up box 103, thus connecting the interior of the placement box 401 and the take-up box 103. By opening the transparent sealing cover 102, the instrument clamping plate 402 can be taken out through the take-up box 103, enabling the taking-up and distribution of instruments. Ventilation holes 307 are provided on the outside of the ventilation sleeve 305, so that when the fan box 304 ventilates the inside of the ventilation mounting plate 301, the sterilization lamp 306 can sterilize the input gas in real time, thus ensuring the cleanliness of the inside of the placement box 401 through the ventilation sleeve 305.
