Problems solved by technology

When the transfer bin has the following defects: it adopts a double-layer structure of inner and outer bins, the inner transfer bin 2 is used to place live animals, and the outer transfer bin 1 is provided with other components, and the inner and outer double-layer structure makes its structure more complex and more difficult to operate. It is cumbersome and bulky; in addition, it lacks air pressure display and alarm functions, and is not easy to use

Embodiment 1

[0057] Such as Figure 1-9 As shown, a kind of virus protection biosafety chamber for the living body fluorescence imager of the present embodiment comprises:

[0058] The warehouse assembly 1 includes a box body 10, a sealed upper cover 11 arranged on the box body 10, an intake high-efficiency filter 12 and an exhaust gas high-efficiency filter 13 arranged in the box body 10, and an outer wall of the box body 10 The air intake check valve 14 communicated with the intake high efficiency filter 12, the air outlet check valve 15 arranged on the outer wall of the box body 10 and communicated with the outlet air high efficiency filter 13, and the air outlet check valve 15 arranged on the bottom plate of the box body 10 A constant temperature plate 16 for placing live animals;

[0059] The electronic module 2 in the warehouse is arranged in the box body 10, and the electronic module 2 in the warehouse includes a control chip, a first battery, a micro switch 20 and an air pressure ...

Embodiment 2

[0076] As a further improvement on the basis of Embodiment 1, this embodiment optimizes the sealing structure between the sealing upper cover 11 and the box body 10, which can greatly improve the sealing performance and prevent harmful gases from sealing the upper cover 11 and the box body. 10 connection leaks.

[0077] refer to Figure 10-13 , in the present embodiment, the middle part of the upper edge of the box body 10 is provided with a circle of the first annular seal groove 101, the first annular seal groove 101 is provided with a seal ring 5, and the bottom surface of the sealing upper cover 11 is provided with a ring for buckling on the seal ring. The annular bead 110 on 5.

[0078] Wherein, the sealing ring 5 is an internal hollow structure, and the sealing ring 5 includes an inner ring 50, a first connecting portion 51, a middle ring 52, a second connecting portion 53 and an outer ring 54 from the inside to the outside in order from the cross section. 50. The firs...

Abstract

The invention discloses a virus protection biological safety cabin for a living body fluorescence imager, comprising: a cabin body assembly which comprises a box body, a sealing upper cover, an air inlet high efficiency filter, an air outlet high efficiency filter, an air inlet one-way valve, an air outlet one-way valve and a constant temperature plate; an internal electronic module, which comprises a control chip, a first battery, a microswitch and an air pressure sensor; the external electronic module comprises a first display screen, a buzzer, a second battery and a first switch; and an air pump module. By arranging the external electronic module, the air pressure value of the box body can be displayed in real time, and the air pressure abnormity alarm function is achieved; meanwhile, the sealing structure between the sealing upper cover and the box body is optimized, the sealing performance can be greatly improved, harmful gas can be prevented from leaking from the joint of the sealing upper cover and the box body, the sealing requirement can be met by adopting a single-layer bin body structure, and therefore the device structure can be simplified, the size of the whole device can be reduced, and operation is easier and more convenient.

Description

technical field [0001] The invention relates to the technical field of biological safety protection, in particular to a virus protection biological safety chamber for a living body fluorescence imager. Background technique [0002] Biosafety laboratories are essential experimental conditions for the study of human infectious disease viruses. When studying active viruses, the effective protection of researchers and the surrounding environment is the basis of research and the basic guarantee for scientific research. [0003] In order to realize the transfer and imaging of live small animals under the conditions of biosafety protection, and to realize the animal live imaging experiments of highly pathogenic viruses, it is of great significance to develop a live small animal transfer device with biosafety protection functions. This device is required to have the following functions: it can store small living animals in a confined space, and can perform live imaging. Negative pr...
