Description

Biochemical detection device

This creation relates to a technical field of biological and chemical testing, especially a testing device with simple structure and easy operation, which can effectively save testing costs and improve testing efficiency, and can avoid environmental pollution caused by improper leakage of samples and extracts.

Press, the easiest way to determine whether you are infected with new coronary pneumonia [Covid-19] is to measure body temperature, but there may be infected persons in the new coronary pneumonia that will not have symptoms of increased body temperature and fever. As the epidemic expands, stricter screening is necessary , And the government has also approved a variety of quick screening reagents to be marketed to provide people with self-screening.

The test kit of the existing quick screening reagent mainly includes a test stick, a test tube, a drip nozzle and a test cassette. Put the test rod into the test tube and stir it with the extract in the test tube and let it stand for a few minutes, then install a drip nozzle on the test tube to drip the extract with the sample in the test tube into the slot of the test cassette, and then wait for 15 minutes After reading the test result, the test cassette is marked with a control line C and a test line T. If the control line does not appear in the test result, the result is invalid. You must use another set of test kits to retest. If the test line does not show up, the test result is negative. If both the control line and the test line show up, the test result is positive, indicating that you may be infected with new coronary pneumonia.

However, it can be seen from the above description that the existing quick screening reagents have a large number of parts, high cost, and complicated operating procedures. During the operation, attention must be paid to whether the cassette is placed flat and the extraction liquid of the mixed sample is dropped. Minor operating errors will affect the accuracy of the test results and need to be re-tested. Therefore, the detection efficiency is low. If the extract of the mixed sample is accidentally dripped elsewhere during the operation, it may cause the spread of the virus. After the test is completed, it takes time to put the sampling probe, test tube, drip nozzle and test cassette into the plastic bag one by one to avoid pollution to the environment and also affect the convenience of use.

The reason is that, in view of the fact that the existing detection devices for new coronary pneumonia and other detection devices still have the above-mentioned shortcomings in the use and implementation, they have used their years of manufacturing and design experience and knowledge in related fields to assist, and after many ingenuities, they have developed This creation.
