Efficient automatic dyeing instrument

Abstract

The invention relates to the technical field of chemical equipment, in particular to an efficient automatic dyeing instrument. The invention aims to solve the problem that the holes of an instrument in the prior art will be blocked after long-time use and are inconvenient to clean. The key points of the technical scheme are as follows: the dyeing instrument comprises a dyeing instrument body whichis connected with a reagent set; a plurality of liquid outlet nozzles communicated with a liquid guide pipe are arranged in the dyeing instrument body, each liquid outlet nozzle is of an L-shaped structure, and a liquid outlet of each liquid outlet nozzle is vertically downward; a pin shaft is arranged at a liquid outlet of each liquid outlet nozzle; each pin shaft is sleeved with a spring, and afirst limiting ring is arranged on the peripheral wall of each pin shaft; a second limiting ring is arranged on the inner wall of the end, close to the liquid outlet, of each liquid outlet nozzle; the springs are limited between the first limiting rings and the second limiting rings; and a position control mechanism for driving the pin shaft to move in the axial direction of the pin shaft to thedirection close to the liquid outlet of the liquid outlet nozzle and then be positioned is arranged between each pin shaft and the corresponding liquid outlet nozzle. According to the invention, the phenomenon of hole blockage of the liquid outlet nozzles can be prevented, and the dripping and leaking of the liquid outlet nozzles after liquid adding can be avoided.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to an efficient automatic dyeing instrument. Background technique [0002] In medicine and biology, in order to observe the histological morphology of tissue samples at the cell and subcellular levels, it is often necessary to stain biological tissue sections coated on glass slides, such as human bodies, but due to the method and time of tissue staining, And the process is often different with the different objects and inspection purposes, so there are many kinds of dyeing. Many hospitals and biomedical researchers usually use manual dyeing. However, manual dyeing is slow, inefficient and the result Less accurate. With the development of medical technology, the dyeing process has become more and more important in medical testing. More and more diseases are diagnosed, and tissue section staining is required in academic research. Therefore, traditional manual dyeing is far...
