Description

Constant-temperature hatching device for rapid detection of trace amount of hair drugs

Technical Field

The utility model relates to a hair drugs trace short-term test uses constant temperature hatching apparatus belongs to and detects technical field.

Background

The quantum dot method is the most advanced drug detection method at present, the hair of drug addicts is extracted, the hair is cracked by protease solution, the extract liquid is used for extraction, after the extract liquid is shaken by a centrifuge, a test tube is used for sampling and dripping on a detection reagent plate, a sample can react with a reagent plate (by adopting an antibody-antigen specific binding reaction and an immune membrane chromatography technology, drugs appearing in the sample are detected by an immune competition inhibition method), the example is Methyl Amphetamine (MAMP), namely, the ice toxin, after a sample reagent plate, a protein-labeled methyl amphetamine carrier can compete with the methyl amphetamine extracted from the hair for antigen binding sites on limited antibodies.

The concentration of the methamphetamine drug added into the sample is different, the T-line fluorescence values detected by the quantum dot method drug detector are different, and the change of the fluorescence values can reflect the concentration of the methamphetamine, so that the drug taking condition of drug taking personnel is judged.

The temperature and the test time of the test environment can influence the reaction, and the test instruments on the market at present directly test the extracting solution after the extracting solution is fully distributed on a reagent plate or insert a machine for testing, and a test result is given after 5 minutes, wherein the temperature and the time of the two modes can generate negative influence on the test result. For example, if the extraction solution is directly inserted into a machine for rapid detection after being spread on a reagent plate, the temperature of the detection environment may affect the accuracy of the test result, and the reaction time is insufficient, which may cause a test error. And (3) inserting the reagent plate into the machine, and outputting the test result after 5 minutes, wherein although the reaction time is enough, the test result is greatly influenced by the ambient temperature, and if the test ambient temperature is very low, the measured result can not be taken as a credible result.

That is, the reaction can be carried out at a fixed temperature for a fixed time to ensure that the reaction reaches an optimal state, and the reaction is most sufficient, so that the accuracy of the detection result of the trace amount of the drug is ensured. In order to ensure the trace detection result of drugs, the reagent plate is usually placed in a constant-temperature oven at present to ensure the complete reaction. However, the above method has the following drawbacks: 1) if a plurality of reagent plates need to be placed inside the oven, then they must be placed at the same time, otherwise opening and closing the oven door can disturb the temperature inside the oven (usually fluctuating by ± 1 ℃), and there is uncertainty about the time for which the extraction solution is spread over the reagent plates, and it needs to be placed immediately into the oven after the extraction solution is spread over the reagent plates, which makes it difficult to place all reagent plates into the oven at the same time. 2) Even if a plurality of batches of reagent plates exist in the oven, the reaction starting time of each batch of reagent plates is different, so that the oven door needs to be opened midway, the temperature fluctuation inside the oven is large when the oven door is opened, the condition that only the reagent plates of the same batch can be placed inside one oven is limited, and the use efficiency of the oven is limited.
