Abstract

The invention relates to a counting plate and a negative film thereof. The negative film comprises a negative film body and a reaction block, wherein the negative film body is provided with an operation surface serving as one side surface of the negative film body, the operation surface is provided with a reaction area and an optical observation area, the reaction block is arranged in the reaction area, the reaction area is used for accommodating a sample capable of pre-reacting with the reaction block, and the optical observation area is used for accommodating a sample to be optically observed. The counting plate disclosed by the invention does not need a special matched instrument, and the whole dyeing process of the sample is carried out in the reaction area and the reaction block, so that the sample is not easy to leak or splash to corrode or pollute other parts.

Description

technical field [0001] The invention relates to the technical field of biological microscope inspection, in particular to a counting plate and its negative film. Background technique [0002] Counting plate is a common biological tool. It is often used in medical devices to microscopically count red and white blood cells and other formed components in the human body. It is also often used to calculate the number of microorganisms such as bacteria, fungi, and yeast. [0003] The traditional counting board requires additional dyeing liquid and other chemical reagent pipelines for supporting instruments, and the structure of the instrument is more complicated. Because the chemical reagents such as dyeing liquid will corrode the relevant pipelines and pump valve devices, the failure rate will remain high, so that ultimately not only It greatly increases the production cost of the instrument, greatly reduces customer satisfaction, and increases after-sales maintenance costs. At ...
