A biological safety cabinet with self-monitoring function and its control method

Abstract

The invention discloses a biological safety cabinet with self-monitoring function. The biological safety cabinet including a biological safety cabinet body, the cabinet body is internally provided with a general control board for controlling the operation of the biological safety cabinet and simultaneously measuring the power supply circuit voltage of the biological safety cabinet, the cabinet body is internally provided with a temperature sensor and a humidity sensor for displaying the temperature and humidity values on a display panel of the biological safety cabinet, so that the user can directly know whether the current temperature and humidity in the biological safety cabinet reach the experimental conditions. The general control board is additionally provided with the function of detecting running voltage and is equipped with a voltage overrun alarm device; in the usage process, the user is able to timely adjust electrical consumption of the laboratory in order to ensure the normal operation of the biological safety cabinet, thereby creating the optimal conditions for the experiment.

Description

technical field [0001] The invention relates to the field of medical equipment, relates to a biological safety cabinet, in particular to a biological safety cabinet with a self-monitoring function and a control method thereof. Background technique [0002] Biological safety cabinets are used to protect the operator, the laboratory environment and experimental materials from exposure to the above-mentioned operations when operating infectious experimental materials such as primary cultures, bacterial strains, and diagnostic specimens. Designed for the possible generation of infectious aerosols and splashes. [0003] 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 biological safety and environmental safety, and belong to the category of "people's livelihood" measurement. As early as 30 ...

Problems solved by technology

[0004] Now due to the increase of electricity users and the reasons of the power supply site itself, the voltage instability often occurs, which makes the fan speed unstable during the operation of the biological safety cabinet. When the user is using it, whether the current voltage reaches The rated voltage of the biological safety cabinet is not known, which causes the fan to work at a non-rated voltage, resulting in unstable fan speed, affecting the inaccurate results of biological and medical experiments in the biological safety cabinet, and the operator's own safety cannot be effectively protected , shorten the service life of the product, and even produce results contrary to the actual results, affecting the progress of medicine and biology

[0005] Some existing medical and biological experiments need to be carried out under specific temperature and humidity conditions, but the existing safety cabinets have no way to set the humidity and temperature, and there is no temperature and humidity detection equipment, which makes the results of these experiments deviate and even affects some important academic research
