Abstract
The utility model discloses a detection device for detecting alcohol contents in human bodies and belongs to the alcohol concentration detection technical field of traffic safety maintenance measures. The device is provided with a digit display screen on the right side of a long circular casing body, a control switch and a sweat vapor collection window which is arranged on the lateral face of the casing body, and an alcohol sensor, a direct current stabilized power supply, a signal regulation and A/D conversion and single-chip microprocessor are further mounted in the casing body. The device is used to detect alcohol contents in human bodies through determining alcohol contents in human body blood by detecting evaporated sweat gas on fingers, and the evaporated sweat gas on fingers can be automatically sampled and analyzed by the detection device to obtain alcohol contents after fingers are contacted with the sensor for seconds. The detection device is capable of accurately and conveniently detecting alcohol contents in driver bodies, and has the advantages of simple and practical effects, stable performances and accurate detection data. The detection device avoids personal factor disturbance and mutual infection, saves materials, and is widely applicable to public security, and judicial departments and drivers for self-testing.
Description
Technical field
The utility model belongs to the alcohol concentration checkout equipment field of traffic safety maintenance measure.Be particularly related to the pick-up unit of alcohol content in a kind of human body.
Background technology
In recent years, along with rapid development of economy, the rapid raising of living standards of the people, the private car that travels on the highway rolls up, and the thing followed traffic hazard that causes of driving when intoxicated takes place again and again.According to interrelated data statistics, in the world 50%～60% traffic hazard with drive when intoxicated relevant.In many countries, traffic accident has become first unexpected death reason, and the economic loss that is caused by traffic hazard is also quite surprising.The Ministry of Public Security drums in recent years and requires various places reinforcement investigation to drive when intoxicated, to reduce the pernicious traffic hazard that causes by driving when intoxicated.Investigate and prosecute with regard to relating to which kind of mode of employing and carry out the problem that alcohol content detects in the human body.
Because after alcohol is absorbed by the body, mainly metabolism in liver of the overwhelming majority, wherein minute quantity alcohol does not have oxygenolysis directly to discharge or discharge from urine through kidney with the sweat gland evaporation from the respiratory tract exhalation or through skin through lung, therefore, judge whether alcohol content exceeds standard in the body, the method for simple possible be on-the-spot detect that human pilot is exhaled or sweat in alcohol content.At present whole world overwhelming majority of countries all adopts expiration formula alcohol content tester that human pilot is carried out scene to detect, with determine alcohol content in measured's body how much.Though exhale to detect the alcohol content that can accurately reflect in theory in the blood of human body, still have the following disadvantages in actual applications: disturbed by peculiar smell such as flue gas; 2, the measured sucks the blowpipe expiration, may pollute mutually; If 3 adopt disposable blowpipe then cause significant wastage; 4, blow gas pressure influential to test result, therefore for serious drunk loss of consciousness or mismatch the personnel of test, exhaling to detect is difficult to carry out; 5, the accuracy of expiration detection is subjected to the influence of selected blowpipe, and improper if blowpipe is selected for use, testing result just can not truly reflect the alcohol content in the human body.
At above-mentioned the deficiencies in the prior art, the present invention looks for another way, adopted by detecting finger sweat and judged the driver whether alcohol content exceeds standard, mutual pollution when preventing to exhale detection, design hommization more, be not subjected to simultaneously the interference of surrounding environment, other people factor, testing result is more accurate.
Summary of the invention
The purpose of this utility model is in the above-mentioned prior art, testing process is disturbed by peculiar smell such as flue gas, the measured sucks blowpipe and exhales, may pollute influential mutually to test result with blow gas pressure, if blowpipe is selected for use improper, testing result just can not truly reflect the deficiency of the alcohol content in the human body, thereby provide the pick-up unit of alcohol content in a kind of human body, it is characterized in that, in the front of Long Circle housing 2 digital display screen 4 is housed, below the digital display screen 4 is gauge tap 3, sweat steam acquisition window 1 is set in the side of housing 2, alcohol sensor 6 is installed in the housing 2 at sweat steam acquisition window 1 back side, and signal condition and A/D conversion 7 also is installed in housing 2, singlechip microprocessor 8; Alcohol sensor 6 is connected the display driver chip of singlechip microprocessor 8 output terminals connection digital display screen 4 by signal condition and A/D conversion 7 with singlechip microprocessor 8; D.C. regulated power supply 5 is connected with alcohol sensor 6.
Described digital display screen is LCD or LED display.
The beneficial effects of the utility model are the alcohol contents that can detect accurately, easily in the human pilot body.Pick-up unit is simple and practical, stable performance, detection data are accurate, can also can be used for human pilot and test oneself after drinking as the judgement instrument of administrative law enforcement.The present invention is not subjected to surrounding environment and interference from human factor, avoids infecting mutually in the testing process, and saves material.

Embodiment
The utility model provides the pick-up unit of alcohol content in a kind of human body.Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by specific embodiment.
Fig. 1, the structural representation that Figure 2 shows that the alcohol content pick-up unit and parts composition frame chart.The digital display screen 4 that LCD or LED constitute is housed in the front of Long Circle housing 2, below the digital display screen 4 is gauge tap 3, the present invention has only a switch, easy and simple to handle, sweat steam acquisition window 1 is set in the side of housing 2, selects for use QM-NJ9 type microsensor module to make alcohol sensor 6, be installed in the housing 2 at sweat steam acquisition window 1 back side, sensitive high to alcohol gas reaction, stable performance, to detect data accurate; The alcohol sensor of installing in housing 26 is connected the display driver chip of singlechip microprocessor 8 output terminals connection digital display screen 4 by signal condition and A/D conversion 7 with singlechip microprocessor 8; D.C. regulated power supply 5 connects alcohol sensor 6, and powers to each several part by alcohol sensor 6.
The principle of alcohol content is as follows in this device human body: the detected person holds pick-up unit, the sweat steam acquisition window above any finger contact alcohol sensor or detect with interior apart from acquisition window 3mm; The well heater that is arranged in the alcohol sensor continues after heating 3s～15s, the sweat rapid evaporation on the finger, and the evaporation sweat is sampled automatically, is analyzed by alcohol sensor by acquisition window; Analyze the gained data and convert digital data transmission to singlechip microprocessor, send to digital display screen then and show alcohol content in detected person's body through signal condition and A/D.Therefore alcohol sensor is quick on the draw the highest to alcohol gas, it is low to be quick on the draw to other other, and even reaction is analyzed, data presented is accurate;
