Multifunctional fully-automatic Gram staining instrument

Abstract

The invention relates to a multifunctional fully-automatic Gram staining instrument. The instrument comprises a glass slide lateral movement device, a microbe automatic staining device, a glass slide entering and departing device, a push rod device and a liquid path control device, the push rod device pushes a coated glass slide positioned on the glass slide entering and departing device into the glass slide lateral movement device, the glass slide moves with a first glass slide rack on a reciprocating movement mechanism to the automatic staining device, is stained, cleaned and blow-dried, the liquid path control device cooperates a computer program in order to control a staining solution in a Gram staining solution bottle to carry out staining, water spraying, gas spraying, drying and other fully-automatic activities on the coated glass slide according to preset steps and time, and the push rod device moves the processed glass slide into the glass slide entering and departing device in order to carry out subsequent operation. The instrument has the advantages of fully-automatic realization of the whole Gram staining process, accurate delivery, cross infection avoiding, staining solution waste avoiding and manpower resource saving.

Description

technical field [0001] The invention relates to a multi-functional automatic Gram staining instrument, in particular to a system that can automate the entire dyeing process according to the set steps and time, and can deliver accurately, safely and quickly, while being environmentally friendly and avoiding cross-infection and dyeing. Liquid waste, and a Gram stainer that saves human resources. Background technique [0002] In the medical field, Gram staining is a differential staining method widely used in bacteriology, which was founded by Danish physician Gram in 1884. Unstained bacteria are extremely difficult to observe under a microscope because of the small difference in refractive index between them and the surrounding environment. After staining, the bacteria are in sharp contrast with the environment, and the shape, arrangement and certain structural features of the bacteria can be clearly observed, which can be used for classification and identification.

Problems solved by technology

[0006] However, the traditional staining method is mainly to stain the fixed bacterial sample through the steps of primary staining, mordant staining, decolorization, and counterstaining. These steps are manually completed by technicians. The operation process is complicated and the staining results vary greatly. This led to the inaccuracy of the experimental results, and at the same time, because the microbial sample was used as a pollution source, it potentially caused pollution to the environment

There are many automatic staining instruments on the market, but there are many deficiencies in the existing technology, including: adopting centrifugal design, the number of staining at one time is small, and the time is long; the flow channel is easy to be blocked; The angle is small, resulting in insufficient spraying effect, and a large amount of reagent spraying is required; the inertia of the magnetic pump is not overcome, resulting in false positive or false negative results in the experiment; the pipeline is long, resulting in waste of reagents, etc.
