Double-cage independent type negative pressure isolation device convenient for space adjustment

Abstract

The invention discloses a double-cage independent type negative pressure isolation device convenient for space adjustment, and belongs to the technical field of biological safety experiment devices. The device includes an isolation cabinet that is internally provided with two isolation cabins which are distributed up and down; two sealing doors are hinged to the isolation cabinet, and the two sealing doors block the two isolation cabins respectively and enable sealed cavities to be formed in the isolation cabins; the two control cabinets are installed on one side of the isolation cabinet in a clamped mode, air exhaust mechanisms are arranged in the control cabinets, and the air exhaust mechanisms communicate with the interior of the isolation bin. According to the invention, the control cabinet is clamped at one side of the isolation cabinet; an air supply device in the control cabinet is independently communicated with the interior of the isolation bin through a first pipe body; an air exhauster in the control cabinet is independently communicated with the interiors of the isolation cabins through a second pipe body, so that each isolation cabin is internally provided with an independent negative pressure system; the negative pressure parameter in the isolation bin can be conveniently and independently adjusted; the invention can flexibly adapt to the requirements of different experiments, and is beneficial to carrying out diversified experiments.

Description

technical field [0001] The invention belongs to the technical field of biological safety experiment devices, and in particular relates to a double-cage independent negative pressure isolation device which is convenient for space adjustment. Background technique [0002] A biosafety laboratory, also known as a biological laboratory, is a place where experiments related to biology are carried out. As the requirements for quality control become more and more stringent, the demand for constant temperature and humidity environment is increasing, and the application fields are becoming wider and wider. Negative pressure isolators, as a first-level isolation device in biosafety laboratories, have also received Wide range of applications. [0003] Chinese patent (CN202110320008.6) discloses an independently ventilated monkey negative pressure isolation device, which includes a host unit and an isolator unit. The number of isolator units is several. The isolator unit includes a box ...

AI Technical Summary

Problems solved by technology

[0004]Currently, the negative pressure isolation device uses multiple chambers connected to one exhaust system, although it saves the input of the exhaust system and reduces the exhaust system However, it is impossible to adjust the ventilation parameters according to the experimental requirements of each monkey cage. At the same time, using a single door to close multiple monkey rooms will cause mutual pollution between the monkey rooms. In addition, the size of the monkey rooms is uniform and cannot be adjusted according to the Adjust the monkey room space according to the experimental goal, thus affecting the experimental results
