Micro dialysis probe

The utility model relates to a micro dialysis probe, which is composed of an inner tube, an outer sleeve tube, a dialysis membrane tube and a right-angle bent outflow tube. The utility model changes many defects that the micro dialysis probe leaves the body, and the inner and the outer components of a cell can not be distinguished exist in the method of collecting the specimen sample with tissue homogenate. By combining the micro dialysis probe with a stereotactic apparatus, hands can be directly extended into each of different positions of the bodies of human bodies, animal bodies, plant bodies, etc. sampling is quick and exact, and the desired component analysis is obtained at the quickest speed; The utility model can be used for the analysis and the investigation in many fields of biology, medicine, botany, environmental protection science, etc., has the advantages of convenient use and accurate and quick sampling and makes the delightful contribution to the sampling of the living body.
