Regent preheating and reaction device and sample analyzer

Abstract

The invention relates to a regent preheating and reaction device. The regent preheating and reaction device comprises a heat converter, a plate type preheating tank and a reaction tank, wherein the heat converter is used for supplying heat and comprises a first part and a second part; the plate type preheating tank forms the first part of the heat converter, a preheating space for accommodating areagent is formed in the plate type preheating tank, and the plate type preheating tank is used for preheating the regent in the preheating space through heat supplied by the heat converter; and the reaction tank forms the second part of the heat converter, a reaction space for accommodating the reagent is formed in the reaction tank, and the preheated reagent reacts with a sample in the reactionspace. The invention provides a sample analyzer. According to the regent preheating and reaction device and the reaction device, the plate type preheating tank and the reaction tank are integrally arranged on the heat converter and can share a set of temperature control system, so that the structure can be simplified, and the cost is lowered.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a reagent preheating and reaction device and a sample analyzer provided with the reagent preheating and reaction device. Background technique [0002] During the use of sample analyzers such as hematology analyzers, reagents are usually preheated before adding samples, and the temperature in the sample reaction pool also needs to be maintained within a certain range to ensure the reaction effect of samples and reagents and obtain more accurate analysis. data. At present, in most instruments, the reagent preheating pool and the sample reaction pool adopt two independent temperature control systems. Each temperature control system includes heating / cooling components, temperature detection sensors, over-temperature protection devices, insulation materials, etc., resulting in complex structures. ,higher cost. In some instruments, two types of holes are formed on the same he...

At present, in most instruments, the reagent preheating pool and the sample reaction pool adopt two independent temperature control systems. Each temperature control system includes heating / cooling components, temperature detection sensors, over-temperature protection devices, insulation materials, etc., resulting in complex structures. ,higher cost

In some instruments, two types of holes are formed on the same heat exchange block by casting, which are used to transport samples and reagents respectively, but the preheating effect is limited, especially when the amount of preheating reagents is large, it cannot meet the actual requirements. requirements, poor versatility
