A protective device for biological experiments used in biological safety laboratories

Abstract

The invention discloses a biological experiment protection device for a biosafety laboratory. The internal air pressure of an operation room and an auxiliary room of the device is controlled through anegative pressure control pump, the operation room and the auxiliary room are in negative pressure with respect to the exterior of a protective cover, the pressure of the operation room is smaller than the pressure of the auxiliary room, and therefore leakage can be effectively prevented, in addition, when experimental equipment or laboratory equipment is added into the operation room, leakage from the operation room can be effectively prevented, matters leak into the auxiliary room even though leakage happens from an operation door of the operation room, the auxiliary room is in negative pressure, and the matters cannot be leaked to the outside; double-layer protection is realized by the double-layer pressure difference; and the protection device adopts the protective cover structure ofa transparent structure, biological experiment personnel can clearly and intuitively observe and understand the conditions, meanwhile, the comprehensive sealing protection effect on biological experimental samples can be achieved, and the operational safety of a biological experiment is ensured.

Description

technical field [0001] The invention relates to a protective device for biological experiments, in particular to a protective device for biological experiments used in biological safety laboratories. Background technique [0002] Existing protective devices for biological experiments used in biosafety laboratories usually adopt an integrated shielding and sealing structure. This structure is not only prone to the risk of leakage during operation, but also the size of the operating gloves is different, and there is a gap between them and the fingers. Larger pores, which makes the operation inconvenient, more importantly, when operating the interior, if you need to put the external items in, you need to open the operation door, which will easily lead to the operation door in the process of putting in. The airflow at the place will flow out, leading to the problem of leakage, which will easily lead to indoor pollution and affect the personal safety of the operator. Moreover, th...

The airflow at the place will flow out, leading to the problem of leakage, which will easily lead to indoor pollution and affect the personal safety of the operator. Moreover, the current equipment cannot clearly and intuitively understand the specific situation inside the protective device, and it is also easy to cause serious damage to the protective gloves. Abrasion phenomena, reducing the service life of guard components
