Drug addict screening method based on pulse waves

Abstract

The invention discloses a drug addict screening method based on pulse waves. The screening method comprises the steps that 1, a pulse wave collection device is adopted for collecting pulse waves of anaddict to be detected first; 2, pulse wave parameters are obtained by processing the pulse waves, and a characteristic variability pattern of the addict to be detected is obtained, and the characteristic variability pattern of the pulse waves is calculated, wherein the pulse wave parameters comprise total pulse wave pulse period time and pulse wave conduction time parameters; 3, judgment is conducted by using a big data model based on the parameters. The drug addict screening method based on the pulse waves lowers the detection cost, simplifies the detection process of drug addicts, shortensthe detection time of the drug addicts and improves the detection successful rate of the drug addicts.

Description

technical field [0001] The invention belongs to the application field of police information technology, in particular to a method for quickly identifying drug addicts based on pulse waves. Background technique [0002] Drug harm is a widespread and serious social problem in our country today. According to the "2016 China Drug Situation Report" issued by the Office of the National Narcotics Control Commission, by the end of 2016, there were about 2.505 million drug users in my country, an increase of 6.8% compared to 2015. Among them, the number of smokers aged 18 to 35 is about 1.464 million, accounting for 58.4%; the number of people aged 36 to 59 is about 1.003 million, accounting for 40%. Drugs can cause long-term irreversible damage to human nervous, respiratory, circulatory and other systems and various organs, and drug abuse will seriously endanger people's physical and mental health. The drug epidemic has caused great losses to the country. First, drug addicts spen...

Problems solved by technology

Drawback of urine testing is undetectable drug ingestion after drug metabolism cycle (usually three days to one week)

In addition, the limitation of urine testing is that drug suspects will not be able to cooperate with the police to discharge urine in time due to nervousness or other reasons, which will affect the detection efficiency

At the same time, the gender composition of grassroots anti-narcotics officers is mostly men, and there are few women. When conducting urine tests on female suspects, it will lead to a shortage of female officers.

Certain foods or medicines such as Jizhi syrup and other cold medicines, as well as products produced by unscrupulous businesses such as hot pot and Malatang will cause false positives and false detections

Moreover, the test strips used in urine testing are disposable consumables, which cannot be reused, and there will be a large expenditure

[0004] Although the accuracy of blood testing is very high, the instruments and equipment required for blood analysis are too expensive and require professionals to operate, which is not suitable for deployment in grassroots anti-drug units
