Automatic cell paraffin block preparation device and method

Abstract

The invention provides an automatic cell paraffin block preparation device and method. The automatic cell paraffin block preparation device comprises a rotary table, a test tube, a semipermeable membrane, liquid taking devices, an extraction device and a pressing device, wherein the test tube is fixed in the first fixing hole in the rotary table and comprises a first tube body and a second tube body; the first tube body and the second tube body are detachably connected with each other; a hole is formed in the bottom of the second tube body; the semipermeable membrane is arranged between the first tube body and the second tube body; the liquid taking devices are used for sucking cell liquid, reagents and liquid paraffin; each liquid taking device comprises a mechanical arm, a suction pipe, first guide tubes and working pumps; the extraction device comprises a fixed part and a second guide tube; the fixed part adopts a hollow structure; an opening in the top of the fixed part is fixedly connected to a hole in the bottom of the second tube body; an opening in the bottom of the fixed part is fixedly connected to one end of the second guide tube; the pressing device is connected to the other end of the second guide tube; positive pressure or negative pressure is provided for the bottom of the test tube through the second guide tube.

Description

technical field [0001] The invention relates to the field of medical electronic equipment, and in particular to a device and method for automatically preparing cell wax blocks. Background technique [0002] Medical treatment of body fluid cells is generally to directly smear the cells with liquid on a glass slide, and then observe through a microscope. With the development of cytopathology in recent years, the limitations of ordinary smears produced by the above conventional techniques have become more and more obvious, such as smears are unique and cannot be copied; they cannot be permanently preserved; Application of histochemistry and molecular pathology techniques. [0003] The cell wax block is to extract the cells in the liquid, fix them in paraffin, and make them into a form similar to tissue slices after fixing. The method solves the problems existing in the above-mentioned common smear, and can also avoid doctor-patient disputes that may be caused by damage or los...
