Description

technical field [0001] The invention relates to the technical field of human blood testing instruments, in particular to a white blood cell classification incubation device. Background technique [0002] In existing blood cytometers, there are two types of reagent preheating devices: split type and integrated type. The split type has a complex structure and takes up a lot of space for installation, which is not conducive to the development of the instrument in the direction of miniaturization. The split type uses a titanium alloy body, which has a low heat conduction system and slow heating speed. For example, the reagent preheating device mentioned in the patent CN201320862224 includes a heat storage block, a reagent container, a heating device, a cover plate, and a sealing device. The device does not include an incubation device and belongs to a split structure. Its reagent preheating device must cooperate with the incubation device In order to realize the pretreatment of...

Problems solved by technology

For example, the reagent preheating device mentioned in the patent CN201320862224 includes a heat storage block, a reagent container, a heating device, a cover plate, and a sealing device. The device does not include an incubation device and belongs to a split structure. Its reagent preheating device must cooperate with the incubation device In order to realize the pretreatment of white blood cell classification, the two must be connected by pipelines, resulting in heat loss, and the incubation device must have a constant temperature environment. All such split preheating incubation devices are complex in structure, troublesome to install, and occupy a large area. The space is large, two heating devices are required, and the cost is high

Patent CN201110215582 mentions a constant temperature reaction system and method for blood reagents. The reagent preheating process and the preheated reagent reaction process are carried out in the same body. The body adopts a low thermal conductivity and is corrosion-resistant to related reagents It is made of titanium alloy with better effect, and a preheating flow channel for the reagent is built in the body, and the reagent flows through the preheating channel to be heated. Although the problem of corrosion resistance is solved, the thermal conductivity of titanium alloy is very small, and the heat transfer effect is very good. Poor, not suitable for large-volume body, the patent also mentions the construction of multiple preheating channels in the titanium alloy body. It is difficult to ensure that there are still problems of sealing and cleaning dead corners at the junction of the corners of the slender channel and the problem that processing debris is not easy to discharge
