Staining instrument and control method for staining instrument

Abstract

The invention provides a staining instrument which is used for tissue slice immumohistochemical staining before a hospital morphology pathological test. The staining instrument comprises a workbench and a mobile mechanical head, wherein the mechanical head is located above the workbench; a suction nozzle area, a reagent area, a recycling area and a staining area are arranged on the workbench; a suction nozzle is arranged in the suction nozzle area; a reagent bottle containing a reagent is arranged in the reagent area; a test block is arranged in the staining area; the mechanical head moves to the suction nozzle area, effectively extracts a suction nozzle and then moves to the reagent area for absorbing the reagent; and then the mechanical head is used for dropwise adding the reagent into the staining area and putting the suction nozzle to the recycling area. The invention also provides a control method for the staining instrument. The control method is used for performing staining operation and comprises the following steps: S1) acquiring the suction nozzle from the suction nozzle area by a sucker of the mechanical head; S2) absorbing the reagent in the reagent area through the suction nozzle by the sucker; S3) dropwise adding the reagent in the suction nozzle onto the test block; S4) separating the suction nozzle from the sucker and placing the suction nozzle into the recycling area. The staining instrument and the control method thereof have the advantages of simpleness, high degree of automation, and the like.

Description

【Technical field】 [0001] The invention relates to the field of medical devices, in particular to a control method for an automatic tissue section staining 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 m...
