There are local accidental cleanliness violations and infection control defects and risks, especially when performing ophthalmic and neurosurgery operations, there is a risk of infection.

[0003] The invention patent with application number: CN202310643304.9 and publication number: CN116950309A (hereinafter referred to as "prior art 1") discloses an air handling air supply ceiling for a clean room, comprising a frame with a plurality of mounting holes and a plurality of ceiling bodies, wherein the top of one of the ceiling bodies is fixedly connected to an air supply pump through a support column.

[0004] The specification of prior art 1 discloses an air-handling air supply ceiling for a clean room. When in use and working, the suction end of the air supply pump can generate negative pressure suction, and the negative pressure suction of the suction end of the air supply pump can cause the transport pipe to generate negative pressure suction, and the negative pressure suction of the transport pipe can cause the junction pipe to generate negative pressure, and the negative pressure of the junction pipe can cause the exhaust pipe to generate negative pressure, thereby causing the gas in the clean room to be extracted through the exhaust port, and then be extracted to the air supply pump through the exhaust pipe, the junction pipe and the transport pipe. After the processing mechanism in the transport pipe processes the gas in the clean room, it enters the clean room through the exhaust end of the air supply pump and the air inlet pipe. Therefore, the gas in the clean room can be processed and the gas in the clean room can be circulated.

[0008] 3. The pipes on both sides of the air supply are not fully connected, and some pipes have large areas and some are small;

[0009] 4. The air supply screen frame is leaking air;

[0010] 5. Strengthening the partitions and ancillary facilities of the shadowless lamp in the air supply ceiling will affect the mixing of the air. Utility Model Content
