Problems solved by technology
When the reagent flows through the syringe of the sampling needle, the reagent will deposit or react chemically due to the temperature change of the environment, and the deposited reagent will remain in the syringe of the sampling needle. If the sampling needle is not cleaned cleanly, it will cause crossover. Pollution, reagents undergoing chemical reactions are changed due to changes in the composition of the reagents, thereby reducing the experimental accuracy of the reagents

The invention relates to a method and a system for controlling the temperature of a sample adding needle. The method comprises the following steps that: a temperature sensor acquires a temperature value of the sample adding needle and feeds the temperature value back to a temperature controller; and the temperature controller judges whether an instruction for temperature processing is needed to be sent to a temperature processing device fixed on the sample adding needle or not according to the temperature value, so that the temperature processing device performs temperature processing on the sample adding needle according to the instruction for temperature processing. By the method and the system for controlling the temperature of the sample adding needle which are provided by the embodiment of the invention, the phenomenon that a needle cylinder of the sample adding needle is blocked because a reagent is deposited due to temperature change is avoided, and chemical reaction of the reagent caused by the temperature change is also avoided, so that the experimental accuracy of the reagent is improved.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a method and system for controlling the temperature of a sample needle. Background technique [0002] At present, in the fields of clinical testing, pharmacy, life science research, animal and plant inspection and quarantine, etc., there are sampling needles for adding samples to instruments, so as to realize the distribution and transfer of reagents. When the reagent flows through the syringe of the sampling needle, the reagent will deposit or react chemically due to the temperature change of the environment, and the deposited reagent will remain in the syringe of the sampling needle. If the sampling needle is not cleaned cleanly, it will cause crossover. Pollution, the chemical reaction reagents will reduce the experimental accuracy of the reagents due to changes in the composition of the reagents. Contents of the invention [0003] The purpose of the present inventi...
