Integrated device for biological protection and control circuit

Abstract

The invention provides an integrated device for biological protection, which comprises an integrated device body for protecting a biological bin, and the integrated device body comprises a detection and control assembly, a control assembly, a processing assembly, a shell and an external assembly. The invention also relates to an integrated control circuit for biological protection. A differentialpressure transmitter is used for detecting the pressure of the gas circuit in real time and feeding back a detected signal to the control assembly, the control assembly sends an instruction to the electromagnetic valve, the gas circuit is closed through the electromagnetic valve, the gas pressure of the gas circuit can be monitored in real time, and danger caused by abnormal failure of the gas circuit is avoided. A filter is also integrated in the device, and the filter can be directly calibrated through a dust particle counter, so that the detection is convenient; the electromagnetic valve isconnected with the filters, the filtering effects of the filters can be monitored in real time, and when the filters are abnormal, the electromagnetic valve closes a gas circuit and calibration is simpler and more convenient.

Description

technical field [0001] The invention relates to the technical field of biological safety protection, in particular to an integrated device for biological protection. 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. Therefore, according to the nature and degree of hazard of the research object, the biosafety level (BSL) is divided into four levels, corresponding to pathogenic microorganisms with different degrees of biological danger, among which biosafety level three laboratories (BSL-3 or P3) and Biosafety level four laboratories (BSL-4 or P4) are called high-level biosafety laboratories. In addition to the laboratory, the biosafety protection in the external transportation process is particularly important....

AI Technical Summary

Problems solved by technology

The pipes in the biological protection process are generally in a negative pressure environment, and the thickness of the pipes is larger than that of ordinary rubber hoses. A separate external filter device will make the equipment appear messy

In addition, when an accident occurs during transportation, there is no effective monitoring device to judge whether the equipment is normal
