Xu Yanli from Hebei Engineering University combined the latest development of current experimental analysis technology and the technical requirements for rapid detection. She chose the convenient and non-invasive clinical collection of saliva as the test specimen for fatigue experimental research, and found some objective clinical markers to assist in diagnosis. It can establish a rapid identification method for fatigue like detecting drunk driving. The collection of saliva samples in the fatigue test is only carried out with test tubes, which causes some saliva to flow to the outer wall of the test tube or splash to the outside of the test tube during the saliva collection process. The splashed saliva will cause potential harm to medical staff and patients. In the collection process, there will be a large amount of saliva foam in the saliva collected in the test tube, which will affect the accuracy of saliva collection and make it difficult for subsequent saliva to enter the test tube again. It affects the effective collection of test samples and thus affects the accuracy of the test; after the test tube is not sealed after the sample is extracted, some dust and impurities will enter the sample, affecting the accuracy of the test result; in addition, during the collection of the saliva sample, the patient directly holds the test tube It will cause the temperature of the test tube to rise, which may invalidate the collected saliva sample.
