Abstract

The utility model relates to a disposable alcohol gas detector, wherein two cavities separated by a gas permeable body are arranged inside a flexible nontoxic transparent container. Strong oxidants are provided inside the front cavity and cobalt dioxide included in a breakable and sealed small purse is provided inside the back cavity; the outer peripheral edge of the small purse matches with the inner wall of the back cavity; a gas ventilative hole is positioned at the bottom end of the back cavity; a plurality of color labels that can indicate occurrence of color changes caused by the chemicals inside the container are provided with the outer wall surface of the transparent container. With comparison between those color labels and the standard color labels a driver can be found if he / she has alcohol intake or reaches the specific alcohol content.

Description

Disposable alcohol gas detecting device

The utility model relates to the instrument that detects alcohol content, refers to a kind of disposable alcohol gas detecting device that utilizes chemical reagent that the driver is driving a car under the influence of alcohol and checks especially.

In the prior art whether the driver is driving a car under the influence of alcohol, usually use the hand-held alcohol detector, it belongs to the electronic gauge category, volume is big, costs an arm and a leg, and generally needs 3000 yuan of Renminbi not wait to 20,000 yuan, before measurement, need the certain content standard specimen is carried out the calibration of 2 of height, during measurement, often be subjected to the influence of a plurality of factors again, signal drift appears easily, make errors of analytical results become big, wayward, and when each the measurement, need carry a lot of disposable interfaces chews, just can carry out everyone use, repeatedly use can cause the pollution of sensor accumulative total, and this hand-held alcohol detector also needs prophylactic repair and maintenance.

The purpose of this utility model is: provide a kind of utilize that chemical reagent detects and accurately safely, be easy to carry, be easy to use, need not calibrate, need not maintain, inexpensive disposable alcohol gas detecting device.

The purpose of this utility model is achieved in that disposable alcohol gas detecting device, main two chambers separating by two ventilative bodies that in the nontoxic transparent vessel of rubber-like, are provided with, be equipped with in the front chamber to be equipped with in strong oxidizer, the rear chamber and be inclusive in the cobaltous dichloride that is easy in damaged and folliculus sealing, the outer peripheral edges of this folliculus and rear chamber's inwall are complementary, the bottom of rear chamber is provided with air hole, and is respectively equipped with all kinds of colour codes that can show internal tank chemical substance generation change color on the outside wall surface of transparent vessel.

The utility model also can be realized by following technical measures: above-mentioned ventilative body is made by ventilative disc plastics; Above-mentioned colour code reaches the colour code of demarcation concentration and the colour code that stop is blown for colour code, strong oxidizer standard colour code, the measured gas of demarcating concentration.

The utility model is owing to utilize chemical reagent as the standard that detects, so it is simple in structure, volume is little, only needs detected person's mouth that container is blown in detection, can compare with Standard Colors by the chemical reagent change in color, detected person's content of drinking as can be known just, and low cost product, it can carry out disposable detection to drinking of driver, and is not only safe but also accurate during use, be easy to carry, need do not calibrate, need do not maintain, greatly reduce cost.

Now further specify by the following drawings and embodiment:

Fig. 1, be structural representation of the present utility model.

Fig. 2, be the utility model outward appearance marked graph.

The utility model proposes a kind of disposablely, can detect the instrument of alcohol gas concentration in the expiration, it just can infer the content (%BAC) that alcohol in the blood in human body in liquid by detecting the concentration of alcohol gas in the oral cavity.

Ultimate principle of the present utility model is: adopt the reaction of alcohol gas in particular chemical reagent and the oral cavity, make the principle of chemical reagent variable color, measure the height of alcohol content.

The concrete practice is: measure the volume of exhaling indirectly with a certain amount of cobaltous dichloride (Coc12).Because the content of moisture content is stable substantially in normal person's breath, can define quantitative gas when a certain amount of cobaltous dichloride is met the water variable color passes through, detecting alcohol content is by alcohol and known a certain amount of strong oxidizer generation oxidation-reduction reaction, known a certain amount of strong oxidizer all is reduced and variable color, thereby know that alcohol content has met or exceeded a certain determined value, if after a certain amount of cobaltous dichloride variable color, strong oxidizer does not have variable color or a little variable color (comparing with the standard colour band), illustrates that then alcohol content is zero or is lower than predefined detected value.So, just can produce different testing products by changing the use amount of cobaltous dichloride and strong oxidizer.Strong oxidizer comprises potassium permanganate, potassium dichromate etc., from point of view of environment protection, thinks that it is best selecting potassium permanganate for use.

Referring to Fig. 1,2, according to above-mentioned principle, the disposable alcohol gas detecting device of designing, mainly in the nontoxic transparent vessel 2 of rubber-like, be provided with by ventilative body 1,4 two chambers separating, strong oxidizer 3 is housed in the front chamber, the outside wall surface of the container 2 of corresponding strong oxidizer 3 is provided with strong oxidizer standard colour band 21, be equipped with in the rear chamber be inclusive in be easy to damaged, and the cobaltous dichloride 5 in the folliculus 6 of sealing, the outer peripheral edges of this folliculus 6 and rear chamber's inwall are complementary, the rear chamber bottom is provided with air hole 7, when external force acts on rear chamber, folliculus 6 is promptly damaged, places the cobaltous dichloride 5 in the folliculus 6 to produce chemical reaction with aqueous vapor.

The outside wall surface of the container 2 between corresponding strong oxidizer 3 and the cobaltous dichloride 5 is provided with that tested gas reaches the colour code 22 of demarcating concentration and the outside wall surface of corresponding air intake opening container 2 is provided with trade mark, demarcates the colour code 20 of concentration, and the outside wall surface of gas outlet container 2 is provided with the colour code 23. of stop air blowing

Its using method is:

1, opens the sealing external packing of container.

2, rear chamber is applied external force, folliculus 6 extruding that are placed with cobaltous dichloride 5 are broken.

3, the air intake opening A from container 2 blows, and until cobaltous dichloride 5 variable colors, then stop is blown through ventilative body 1,4, and gas is discharged by gas outlet B.

4, wait for certain hour after, the variable color situation of observing strong oxidizer 3 compares with the demarcation concentration 20 and the strong oxidizer standard colour band 21 of container 2 outside surfaces.

If strong oxidizer 3 variable color degree do not reach standard colour band 21 colors, illustrate that alcohol concentration in the blood of human body does not reach the demarcation concentration 20 of detecting device, so the measured does not drink or do not reach the demarcation alcohol content.

If strong oxidizer 3 variable color degree reach standard colour band 21 colors, illustrate that alcohol concentration in the blood of human body meets or exceeds the demarcation concentration 20 of detecting device, so having, the explanation detected person drinks or the problem of excessive consumption of alcohol.This disposable alcohol gas detecting device is significant for the awareness of safety that improves the driver, the traffic safety behavior of standard society.
