Method for measuring alcohol content in human body and device therefor

Abstract

The invention discloses a method for measuring the alcohol content in the human body and a device therefor, belonging to the technical field of alcohol concentration measurement of the traffic safetymaintenance measure. The device comprises a long circular shell, the front of which is provided with a digital display screen and a control switch, and the side thereof is provided with a sweat steamcolleting window; and the shell is also internally provided with an alcohol sensor, a DC stabilized power supply, a signal conditioning and A / D convertor and a singlechip microprocessor. The method for measuring the alcohol content in the human body by utilizing the device comprises: the alcohol content in the blood of the human body can be determined by measuring the sweat evaporation gas of fingers; and after the fingers touch the sensor for a plurality of seconds, the sweat evaporation gas of the fingers can be automatically sampled and analyzed by the measuring device, so that the alcoholcontent can be obtained. The invention can accurately and conveniently measure the alcohol content in the driver body. The measuring device is simple and practical, stable in performance and accuratein measurement data. Furthermore, the invention can avoid the interference of human factor and mutual infection, saves material and can be widely applied to public prosecutor law enforcement agenciesand self testing by drivers.

Description

technical field [0001] The invention belongs to the technical field of alcohol concentration detection for traffic safety maintenance measures. In particular, it relates to a method and a device for detecting alcohol content in a human body. Background technique [0002] In recent years, with the rapid development of the economy and the rapid improvement of people's living standards, the number of private cars driving on the road has increased a lot, and the traffic accidents caused by drunk driving have occurred frequently. According to relevant statistics, 50% to 60% of traffic accidents in the world are related to drunk driving. In many countries, traffic accidents have become the first cause of accidental death, and the economic losses caused by traffic accidents are quite staggering. In recent years, the Ministry of Public Security has repeatedly emphasized that all localities should strengthen the investigation and punishment of drunk driving in order to reduce vicio...

Problems solved by technology

Although the breath test can accurately reflect the alcohol content in human blood in theory, there are still the following deficiencies in practical application: 1. It is easily disturbed by peculiar smells such as smoke during the test process; 3. If a disposable blowpipe is used, it will cause great waste; 4. The blowing pressure will affect the test results. Therefore, it is difficult to carry out the breath test for those who are seriously drunk and lose consciousness or do not cooperate with the test. ;5. The accuracy of the breath test is affected by the selected blowpipe. If the blowpipe is not selected properly, the test result cannot truly reflect the alcohol content in the human body
