Abstract
The utility model relates to an on-spot quick blood alcohol concentration tester. One of two electrodes of an alcohol concentration sensor is connected with a sampling resistor, the other end of the sampling resistor is connected with one end of a numerically controlled precision regulated power supply, and the other electrode of the alcohol concentration sensor is connected with the other end of the numerically controlled precision regulated power supply; both ends of the sampling resistor are connected with a digital-to-analog conversion module, and the digital-to-analog conversion module is connected with a computer system. The invention has the following advantages that: the on-spot quick blood alcohol concentration tester can instantly test the blood alcohol concentration of a driver on the driving spot, and thereby can instantly judge whether the driver drinks or not on the spot. Consequently, the utility model can effectively stop drunk drivers, thus avoiding the occurrence of traffic accidents.
Description
Technical field
The utility model belongs to the Electrochemical Detection instrument, particularly a kind of blood of human body alcohol content field quick detection instrument.
Background technology
The easy accidents caused reason of driving when intoxicated is the principal ingredient ethanol of wine, because ethanol can have very big influence to people's nervous system.The foundation of judging when the driver drives 80% is from visual determination, and under the state of, Consciousness clear in vision, traffic hazard just is difficult for taking place, and can make people's eye-blurred unclear but drink.And because the effect of alcohol, people's balanced capacity, the order of accuarcy of action all can reduce greatly, thereby action is morphed.In addition, drinking also to make reaction capacity reduction, the locomitivity imbalance of brain to accident, and because of the alcohol anesthetic action, people's hand, pin sense of touch reduce more at ordinary times, often can't normally control throttle, brake and bearing circle.At this moment drive very easily to cause accident as accident.Many countries have all formulated the relation of ethanol in blood content and traffic accident responsibility identification, have set up the multiple method that can detect ethanol in blood content.As instrument detecting alcohol components such as GC/MS, though these methods can be quantitative, exist the purchase instrument and cost an arm and a leg, detect the cost height, need special training, can't be in scarce limits such as spot fast detecting.Expiration formula alcohol determining instrument can use at the scene, but price is also very expensive, detects the cost height, and unhygienic, cross infection disease takes place easily and be subjected to that easily artificial false expiration influences etc.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of blood of human body alcohol content field quick detection instrument is provided.Can instant at the scene fast detecting analysis driver whether drink.
The technical solution of the utility model is:
A kind of blood of human body alcohol content field quick detection instrument, it is characterized in that: an electrode in two electrodes on the ethanol content sensor connects sample resistance, the sample resistance other end connects numerically-controlled precise stabilized voltage supply one end, and another electrode in two electrodes on the ethanol content sensor connects the numerically-controlled precise stabilized voltage supply other end; The two ends of sample resistance connect D/A converter module, and D/A converter module connects computer system.
Computer system connects display and keyboard by computing machine.
The utility model effect is:
Whether this human body blood alcohol content on site fast detecting instrument can carry out the instant test of blood ethanol content fast to the driver at the driving scene, drink thereby can judge the driver at the scene immediately apace.Thereby can prevent the people that drinks to drive the generation that avoids traffic accident effectively.During use, as long as tested person's blood is spread upon on the ethanol test sheet on the ethanol content sensor, because the ethanol in the blood makes the electric conductivity of ethanol content sensor change, just the ethanol content sensor resistance changes, at this moment the voltage at the two ends of the sampling of blood of human body alcohol content field quick detection instrument changes, at this moment will detect voltage by D/A converter module and be input to computing machine, contain the resistivity data contrast of different ethanol contents with ethanol test sheet in the database, just measure by the side personnel at once, ethanol content in the blood, again through with blood in ethanol content and the database contrast of human body drinking amount contrast, promptly judge out drinking amount by the side personnel.
Description of drawings
Fig. 1 is the structural representation of blood of human body alcohol content field quick detection instrument
Embodiment
A kind of blood of human body alcohol content field quick detection instrument as shown in Figure 1, an electrode in two electrodes on the ethanol content sensor connects sample resistance, the sample resistance other end connects numerically-controlled precise stabilized voltage supply one end, and another electrode in two electrodes on the ethanol content sensor connects the numerically-controlled precise stabilized voltage supply other end; The two ends of sample resistance connect D/A converter module, and D/A converter module connects computer system.Computer system connects display screen and keyboard by computing machine.
Wherein the ethanol content sensor is obtained by following method step: (this sensor has been applied for a patent and has been the preparation method of carbon nanofiber electrochemistry biology sensor.)
Pass through processing to carbon nano-fiber CNF:
1mg-100mg carbon nano-fiber CNF is distributed to 10-60ml, and in the 10%-60% salpeter solution, potpourri was 30 ℃ to 150 ℃ heating 1 hour to 48 hours; Product obtains the CNF of carboxylation after through centrifugal and washing; Obtain the carbon nano-fiber CNF aqueous solution of 1-10mg/ml by carbon nano-fiber CNF ultrasonic dispersion in water; Carry out the preparation of CNF and enzyme modified electrode again: glass-carbon electrode is used the aluminium oxide powder polishing of 1,0.3 and 0.05 μ m successively, then with the flushing of secondary water; After drying up with nitrogen, 1-20 μ L, the 0.2M of 0.5-10mg/ml alcohol dehydrogenase, the phosphate buffer solution of pH 5-9 drips to glass-carbon electrode, dry 30min in exsiccator; And then the carbon nano-fiber CNF solution that drips 1-20 μ L drips on the glass-carbon electrode and the dry carbon nanofiber electrochemistry biology sensor that gets in exsiccator.
Apply the system conducting film respectively on the two sides of carbon nanofiber electrochemistry biology sensor again, form the ethanol content sensor that two electrodes are promptly arranged.
Computer system has display screen except that main frame, keyboard, and alarm unit.
During use, as long as tested person's blood is spread upon on the ethanol test sheet on the ethanol content sensor, because the ethanol in the blood makes the electric conductivity of ethanol content sensor change, just the ethanol content sensor resistance changes, at this moment the voltage at the two ends of the sampling of blood of human body alcohol content field quick detection analytic system changes, at this moment will detect voltage by D/A converter module and be input to computing machine, and contain the resistivity data contrast of different ethanol contents with ethanol test sheet in the database, just measure by the side personnel at once, ethanol content in the blood, again through with blood in ethanol content and the database contrast of human body drinking amount contrast, promptly judge out drinking amount by the side personnel.
