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
The invention belongs to a kind of pick-up unit, be specifically related to a kind of ethanol content detection device.
Background technology
At present, ethanol content detects and mainly contains expiration formula ethanol detector and the special-purpose chromatograph of ethanol in blood content detection in the known blood of human body.The formula of wherein exhaling ethanol detector is by allowing tested people by the gas to the satisfactory tested people of expiration formula ethanol detector exhalation vents incoming call, then by the pneumoelectric conversion, to obtain the ethanol content in tested people's human body blood.This kind measuring error is bigger.Use the special-purpose chromatograph of ethanol in blood content detection, tested people must be taken to the special-purpose chromatographic test cabinet of ethanol in blood content detection is housed, by extracting tested people's blood, inject the special-purpose chromatograph of ethanol in blood content detection then, and measure ethanol content in tested people's human body blood by the spectrum test of this blood.Though it is relatively accurate, very inconvenient that this kind measured, and loses time.In addition, at present saliva ethanol content test strip human body ethanol in blood content is with the naked eye saliva ethanol content test strip relatively to be judged ethanol content in tested people's human body blood with standard sample, can introduce like this to think error.
Summary of the invention
In order to overcome the existing deficiency that saliva ethanol content test strip is carried out the ethanol content of blood of human body of with the naked eye carrying out, the invention provides a kind of ethanol content detection device, this ethanol content detection device can not only overcome may be by the error of artificial introducing, and can be convenient for carrying.
The technical solution adopted for the present invention to solve the technical problems is:
Ethanol content detection device comprises test strips slot 1, test strips folder 2, test strips 3, calibration pad 4, limit light pipe 5, light emitting diode 6, photoelectric cell 7, circuit board 8, shell 9, LCD 10 is provided with circuit board 8 in the ethanol content detection device, circuit board 8 is by signal adjustment circuit, the single-chip microcomputer that contains A/D converter, storer is formed, ethanol content detection device has calibration pad 4 and test strips slot 1, be provided with the test strips folder 2 of band groove in the test strips slot 1, be provided with test strips 3 in the groove, test strips 3 is provided with limit light pipe 5, limit light pipe 5 is provided with photoelectric cell 7, photoelectric cell 7 both sides are provided with light emitting diode 6, and photoelectric cell 7 is provided with circuit board 8, light emitting diode 6 and circuit board 8 welding.Photoelectricity 7 can also be substituted by among CMOS or the CCD any one.When calibration detected: the axis of limit light pipe 5 coincided with the front center perpendicular line of calibration pad and the center vertical line of photoelectric cell 7 light-sensitive surfaces.When ethanol content detected: the axis of limit light pipe 5 coincided with the front center perpendicular line of test strips and the center vertical line of photoelectric cell 7 light-sensitive surfaces.
The present invention compared with prior art has the following advantages: volume is little, is easy to carry, and avoids artificially introducing error.
