Description

Technical Field

[0001] The utility model relates to the technical field of biological safety cabinets, in particular to a novel protective medical biological safety cabinet. Background Art

[0002] The protective medical biosafety cabinet is a device that provides safety protection when operating infectious experimental materials such as primary cultures, bacterial strains, and diagnostic specimens. Its main purpose is to protect the operator, the laboratory environment, and the experimental materials, and avoid exposure to infectious aerosols and splashes that may be generated during the operation. The protective medical biosafety cabinet is an indispensable safety equipment in the laboratory and is of great significance to ensuring biological safety and environmental safety.

[0003] The use of protective medical biosafety cabinets has strict requirements. Generally speaking, the interior of the biosafety cabinet belongs to the A-level environment, and the general clean room (laboratory) environment is C-level or B-level. During the use of the biosafety cabinet, it is often necessary to take out the used discarded pipettes, culture bottles and other items from the safety cabinet and throw them into the waste bin. At this time, the operator's arms will go in and out of the biosafety cabinet back and forth, switching back and forth between the C-level or B-level environment and the A-level clean environment of the biosafety cabinet, which does not meet the requirements of the pharmaceutical production quality management standard operation, and there are great hidden dangers in product production quality. Therefore, in order to ensure product quality, the operator's arms are preferably kept in the A-level environment inside the biosafety cabinet at all times during the operation to maintain sterile operation; for this reason, a new protective medical biosafety cabinet is proposed.

A collection pipe 6 is fixedly connected to the left side of the lower surface of the biosafety cabinet body 1, and the collection pipe 6 is located directly above the garbage collection bucket 5. The top of the collection pipe 6 extends into the interior of the biosafety cabinet body 1, and an installation box 7 is fixedly connected to the left side of the inner bottom wall of the biosafety cabinet body 1. An electric cylinder 8 is fixedly installed on the inner bottom wall of the installation box 7, and one end of the piston rod of the electric cylinder 8 passes through the upper surface of the installation box 7 and is fixedly connected to a connecting frame 9, and a cover plate 10 is fixedly connected to the right end of the connecting frame 9. The lower end of the cover plate 10 A conical silicone ring 11 is bonded to the surface, and an annular sealing groove 12 is provided on the upper surface of the collecting tube 6; when the biosafety cabinet body 1 is used normally, the piston rod end of the electric cylinder 8 is shortened to drive the cover plate 10 to move downward to cover the collecting tube 6, and the conical silicone ring 11 is inserted into the annular sealing groove 12, ensuring that the biosafety cabinet body 1 and the external environment are isolated at the collecting tube 6. When it is necessary to discard waste pipettes, culture bottles and other wastes, the piston rod end of the electric cylinder 8 is extended to drive the cover plate 10 to move upward to expose the top opening of the collecting tube 6. At this time, the used waste can be put into the collecting tube 6, and then the waste will fall directly into the garbage collection bin 5 along the collecting tube 6. The operator's arms do not need to go in and out of the biosafety cabinet body 1 back and forth, which can avoid the mutual contamination between the experimental materials and the external environment of the biosafety cabinet, thereby facilitating product quality assurance.

[0031] The working principle of the utility model is: after the biosafety cabinet is moved to the target position by means of the roller 14, the top plate 18 is driven to move downward to support the ground by rotating the screw rod 17 clockwise, so as to increase the support area and improve the stability of the biosafety cabinet. The friction between the rubber pad 19 and the ground can prevent the biosafety cabinet from moving accidentally. When the biosafety cabinet body 1 is used normally, the piston rod end of the electric cylinder 8 is shortened to drive the cover plate 10 to move downward to cover the collection tube 6, and the conical silicone ring 11 is inserted into the annular sealing groove 12 to ensure the biosafety. The cabinet body 1 is isolated from the external environment at the collecting tube 6. When it is necessary to discard waste such as discarded pipettes and culture bottles, the cover plate 10 is driven to move upward by extending one end of the piston rod of the electric cylinder 8 to expose the top opening of the collecting tube 6. At this time, the used waste can be put into the collecting tube 6, and then the waste will fall directly into the garbage collection bin 5 along the collecting tube 6.
