Description
技术领域technical field

背景技术Background technique
生物安全柜广泛应用在医疗卫生、疾病预防与控制、食品卫生、生物制药，环境监测以及各类生物实验室等领域，是保障操作人员、生物和环境安全的重要基础。但是传统生物安全柜只能保证操作环境的无菌程度，而无法控制其中的温度、湿度和氧气浓度。因此，在生物安全柜中难以操作对温度、湿度和/或氧气敏感的微生物或细胞。Biological safety cabinets are widely used in medical and health care, disease prevention and control, food hygiene, biopharmaceuticals, environmental monitoring, and various biological laboratories. They are an important basis for ensuring the safety of operators, biology, and the environment. However, traditional biological safety cabinets can only guarantee the sterility of the operating environment, but cannot control the temperature, humidity and oxygen concentration in it. Therefore, it is difficult to manipulate microorganisms or cells that are sensitive to temperature, humidity and/or oxygen in a biological safety cabinet.
目前市面上采用的生物安全柜为配备风淋的手套箱，其结构通常是利用一个风机将惰性气体压过一块过滤层流板，达到对气体中微粒的去除，然后惰性气体中的氧气则通过另一套风机鼓入一个装有氧吸收剂的罐体中进行吸收；这样的手套箱不仅体积庞大，而且部件较多；同时由于安装管径的限制，使得脱氧速率较低且能耗高。The biosafety cabinet currently used in the market is a glove box equipped with an air shower. Its structure is usually to use a fan to press the inert gas through a filter laminar flow plate to remove the particles in the gas, and then the oxygen in the inert gas is passed through. Another set of blower blows into a tank containing oxygen absorbent for absorption; such a glove box is not only bulky, but also has many parts; at the same time, due to the limitation of the installation pipe diameter, the deoxygenation rate is low and the energy consumption is high.
