Problems solved by technology

Although this measurement is relatively accurate, it is inconvenient and time-consuming
In addition, the current saliva ethanol content detection test strips are used to detect the ethanol content in human blood by comparing the saliva ethanol content detection test strips with the standard sample with the naked eye to determine the ethanol content in the human blood of the tested person, which will introduce errors

Abstract

The invention discloses an ethanol content detection device. A shell (9) of the ethanol content detection device is provided with an LCD (10), a circuit board (8) is arranged inside the ethanol content detection device, a calibration pad (4) and a test paper strip slot (1) are arranged below the ethanol content detection device, a test paper strip clamp (2) with a groove is arranged inside the test paper strip slot (1), a test paper strip (3) is arranged inside the groove, a light limiting tube (5) is arranged on the test strip (3), a photocell (7) is arranged on the light limiting tube (5), two sides of the photocell (7) are arranged with LEDs (6), the circuit board (8) is arranged on the photocell (7), and the LEDs (6) is welded with the circuit board (8). Light from the LEDs shoots on the test paper strip and is reflected to the photocell by the light limiting tube, passes through a signal adjustment circuit, and is acquired, computed, displayed and stored by an A / D converter in a single-chip microcomputer, which can quickly and exactly obtain alcohol content detection for a human body and effectively prevent a detection result from being affected by human factors.

Description

technical field [0001] The invention belongs to a detection device, in particular to an ethanol content detection device. Background technique [0002] At present, the known detection of ethanol content in human blood mainly includes a breath type ethanol detector and a special chromatograph for detection of ethanol content in blood. Among them, the breath type ethanol detector is to let the person being tested breathe in the gas of the person being tested that meets the requirements through the exhalation port of the breath type alcohol detector, and then through gas-to-electric conversion, to obtain the blood concentration of the person being tested. ethanol content. This measurement error is large. To use a special chromatograph for the detection of ethanol in blood, the person to be tested must be brought to the test room equipped with a special chromatograph for the detection of ethanol in blood. By drawing the blood of the person to be tested, and then injecting it i...
