System for controlling and monitoring bacteria in biological 3D printing clean room

Abstract

The invention discloses a system for controlling and monitoring bacteria in a biological 3D printing clean room. The system can solve the problem of poor sealing ability of existing biological 3D printing clean rooms, gets rid of the dependence on a biological safety cabinet, and can simultaneously monitor and assess the bacteria in the clean room. The system for controlling and monitoring bacteria in the biological 3D printing clean room includes a sterilization system and a monitoring system which are arranged inside the clean room, and a sealing system arranged outside the door of the clean room, the sterilization system includes an air filtering device and a disinfecting and sterilizing device; and the air filtering device adopts an FFU fan filter unit, the disinfecting and sterilizing device selects a 200-275 nm C wave ultraviolet sterilization lamp, the monitoring system includes a laser suspended particle counter and a support vector machine, and 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...
