Transferring disinfecting device for pollutants in P3-grade biosafety cabinet

Abstract

The invention discloses a transferring disinfecting device for pollutants in a P3-grade biosafety cabinet. A discharge opening is formed in one side of the biosafety cabinet; an isolating door capable of being opened inwards is arranged at the discharge opening; the disinfecting device comprises a negative pressure exhaust cabinet with a sealed inner cavity, a high pressure disinfecting barrel arranged in the negative pressure exhaust cabinet, and a delivery barrel accommodated in the high pressure disinfecting barrel; the delivery barrel comprises a hollow barrel body, a delivery pipe fixedly connected to the opening part of the hollow barrel body and made of soft material, and an electromagnetic door which is fixedly arranged at the opening part of the delivery pipe and is capable of being opened or closed; a delivery opening for the delivery pipe to pass out is formed in one side of the negative pressure exhaust cabinet; a delivery door capable of being opened inwards is arranged at the delivery opening; the electromagnetic door can be sucked on the outer side of the biosafety cabinet in an electromagnetic manner and is positioned on the circumferential outer side of the discharge opening. The transferring disinfecting device can completely isolate the inner environment from the outer environment, avoids the direct contact between people and pollutants, reduces the labor intensity of operators, and eliminates secondary pollution.

Description

technical field [0001] The invention relates to the technical field of biological experiment equipment, in particular to a P3 level biological safety cabinet pollutant transfer disinfection device. [0002] Background technique [0003] Biological safety cabinets are used to protect the operator, the laboratory environment and experimental materials from exposure to the above-mentioned operations when operating infectious experimental materials such as primary cultures, bacterial strains, and diagnostic specimens. Designed for the possible generation of infectious aerosols and splashes. [0004] Biological safety cabinets are divided into three categories: Class I, Class II and Class III to meet different biological research and epidemic prevention requirements. The P3 biological safety cabinet is designed for the P4 laboratory biosafety level. It is currently the world's highest safety protection level safety cabinet, and its disinfection level is relatively high. The bi...

Problems solved by technology

Among them, each isolator is equipped with two double-door transfer interfaces. Although the use of isolators can improve the safety of staff and operating procedures and reduce the pollution area, the two double-door transfer interfaces set by the isolator cannot be completely sealed. It will still cause bacteria to be hidden in the gap between the two doors, and the isolation transfer system is composed of an ALPHA transfer door with a double-door transfer interface and a transfer bucket with a BETA door on the top. The transfer bucket needs to be directly connected to the transfer door before it can be disinfected. Generally, the weight of an empty bucket is 10-20 catties, and the weight of a full bucket is 30-40 catties. For experimenters, especially women, it is more laborious to load and unload the full bucket.
