Pneumatic micro-operation device for tiny organisms

Abstract

The invention discloses a pneumatic micro-operation device for tiny organisms, which comprises a controller, a negative pressure vacuum pump, a negative pressure throttle valve, a vacuum proportional valve, an adsorption electromagnetic valve, a pressure sensor, a micro-attitude adjustment component, a positive pressure gas pump, a positive pressure throttle valve, a positive pressure proportional valve, a release electromagnetic valve, a speed control valve and a tail-end micro-clip. The pneumatic micro-operation device can be divided into a negative pressure adsorption gas path and a positive pressure release gas path, thereby carrying out adsorption micro-operation and release micro-operation. The pneumatic micro-operation device has the advantages that the operation tail end has the micro-attitude adjustment function and can realize sorting, screening and other micro-operations of the tiny organisms without injuring and damaging the organisms, and the pneumatic micro-operation device can improve the efficiency and the success rate of operation staff, reduce the working strength and have broad practical application prospects and value by being applied in the field of biomedicalresearch.

Description

technical field [0001] The invention relates to a pneumatic micro-operation device for tiny organisms, which is suitable for operations such as sorting and screening of tiny organisms and tiny particles, and belongs to the technical field of biomedicine. Background technique [0002] In the field of life science research, model organisms are often studied as selected biological species to reveal certain life phenomena with universal laws; as a typical representative of model organisms, Caenorhabditis elegans is a multicellular animal with a The development process is similar to that of human beings. Biologists have conducted many scientific experimental studies and discovered the essential mechanisms of many diseases, which has brought good news for human beings to prolong life and live a better life. [0003] Although the research on model organisms has been paid more and more attention, the development of automatic sorting devices for model organisms, especially nematodes,...

AI Technical Summary

Problems solved by technology

[0006] In short, although some progress has been made in the research work on micromanipulation at home and abroad, there are still the following problems: 1) The automatic operation device for tiny organisms has not yet appeared; 2) The current vacuum micromanipulation devices all use compressed air pumps It is used in conjunction with a vacuum generator, and the device has a large structure, which is not easy to move and be portable; 3) Most vacuum micro-manipulation devices are open-loop operation devices because their objects are solid particles, and the control accuracy is not high.
