Bio 3D printing clean room bacteria control and monitoring system

Abstract

The invention discloses a biological 3D printing clean room bacterium control and monitoring system. This system can solve the problem of poor sealing ability of the existing biological 3D printing clean room, and get rid of the dependence on the biological safety cabinet. Conduct monitoring and evaluation. The following technical solutions are used to achieve: bio-3D printing clean room bacterium control and monitoring system, including a sterilizing system installed inside the clean room, a monitoring system and a sealing system set at the door of the clean room, the sterilizing system includes air Filtration device and disinfection and sterilization device; The air filtration device adopts FFU fan filter unit, and the disinfection and sterilization device selects a C-wave ultraviolet sterilizing lamp with a wavelength range of 200-275nm, and the monitoring system includes a laser suspended particle counter and a support vector machine , the sealing system is an inflatable sealing system.

Description

technical field [0001] The invention relates to a biological 3D printing clean room bacteria degree control and monitoring system, belonging to the technical field of biological 3D printing equipment. Background technique [0002] Bio-3D printing is the application of 3D printing technology in the field of biomedicine. It combines 3D printing technology with medicine, biomaterials and computer technology to create 3D models for specific anatomical structures and physiology of patients. Bio-3D printer is a kind of equipment that can position and assemble biological materials or cell units according to the principle of additive manufacturing under the drive of digital three-dimensional model, and manufacture medical devices, tissue engineering scaffolds, tissues and organs and other products. Or design a three-dimensional model, discretize the model into multiple layers, and the computer controls the printing nozzle to print biological materials or cells layer by layer until t...
