Embodiment 1

[0032] Embodiment 1 is used for the multifunctional sampling detection stick of saliva, DNA sample collection and alcohol detection

[0033] refer to Figure 1-Figure 2 , the multifunctional sampling detection stick for saliva, DNA sample collection and alcohol detection provided in this embodiment consists of a sheath (can be omitted), a sponge head, a handle, a micro-toothed scraper, a hollow collection tube, and a groove embedded in the handle The saliva alcohol detection test strip is composed of several parts. The sponge head is adjacent to the micro-tooth scraper, and then connected to the front end of the hollow handle with a collection tube. The handle is provided with a groove, and the saliva alcohol test paper is fixed in the groove. One end of the hollow collection tube communicates with the sponge head, the other end communicates with the saliva alcohol test paper, and the rear end of the handle is flat and easy to hold.

Embodiment 2

[0034] Embodiment 2 is used for the test kit and application of saliva, DNA sample collection and alcohol detection

[0035] The test kit for saliva, DNA sample collection and alcohol detection provided by the present embodiment includes the multifunctional sampling detection stick of embodiment 1, the standard color card for measuring the alcohol content in the saliva sample, cell preservation solution (PBS buffer solution) ) and sampling tubes. Among them, the cell preservation solution and the sampling tube are used to preserve the oral mucosal cells and epithelial tissue collected from the sampling test stick.

[0036] When in use, insert the sponge head of the multi-functional sampling test stick into the oral cavity ( image 3 ), the saliva is first sucked into the sponge head, then introduced into the hollow collection tube connected to the back of the sponge head, and then flows into the saliva alcohol test strip through the collection tube from the other end. Finall...

Abstract

The invention provides a multifunctional sampling detection rod used for saliva and DNA (deoxyribonucleic acid) sample collection and alcohol detection. The multifunctional sampling detection rod comprises a holding part, a sampling part and a detection part, wherein the sampling position is positioned on one end of the holding part and is connected with the detection part arranged on the holdingpart; an adsorption material used for adsorbing a saliva sample is fixed on the sampling part; the detection part is provided with an alcohol detection test strip. The multifunctional sampling detection rod disclosed by the invention has the advantages of convenience in use and simpleness in operation, DNA sample collection can be finished while the saliva is collected, and three indexes are detected for saliva alcohol contents. The multifunctional sampling detection rod has the advantages of simple structure and small volume, is suitable to use in field during law enforcement and is also verysuitable to use for individuals and families according to requirements. Painless collection is realized, no trauma or invasiveness is in the presence, and a user does not generate discomfortableness.The multifunctional sampling detection rod is used in one time, and no cross infection risks are in the presence. The collected DNA sample is suitable for genetic analysis detection, other medical examinations and the like.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a multifunctional sampling and detection stick for collecting saliva and DNA samples and detecting alcohol. Background technique [0002] With the rapid development of China's automobile industry and the improvement of people's living standards, motor vehicles and new drivers are increasing rapidly. Now many traffic accidents are related to drug driving, drunk driving and drunk driving. According to the national standard GB19522-2010 "Vehicle Drivers Blood and Breath Alcohol Content Threshold and Inspection", the driver's blood content reaches 20mg / 100ml is drunk driving, and the blood content reaches 80mg / 100ml is drunk driving. Currently commonly used blood testing methods require professionals and equipment, the process is complicated, and on-site testing cannot be completed. Exhalation alcohol detectors are the most widely used in law enforcement. The instruments used are exp...
