Description
technical field [0001] The invention relates to the field of temperature control of medical equipment, in particular to a temperature control device and a constant temperature control method. Background technique [0002] Class II inspection medical devices, including coagulation analyzers, need to be equipped with temperature control devices to meet the requirements for temperature control in the detection working state. In order to improve the operating efficiency of the equipment, the commonly used testing medical equipment now mostly uses rotary devices as the sample and reagent position devices. Most of these devices involve the detection of blood and test reagent samples, and blood and test reagents have higher temperature requirements. , Blood samples are generally required to be stored at room temperature, reagents are required to be stored at 2°C-8°C, and testing is required to work at 37°C, and the temperature control requirement is ±0.5°C. [0003] Currently, due...
