Embodiment 1

[0029] Such as figure 1 Shown, a kind of human breath alcohol concentration testing device, it comprises breath sampling bag 1, one-way air valve, reagent tube 2, pipe cap 3 and two pipe body plugs 4; Wherein, described one-way air valve Including a valve cylinder 5 and a valve core 6 arranged in the valve cylinder 5, one end of the valve cylinder 5 is sealed and connected with the breath sampling bag 1, and the sealing end of the tube cap 3 is inserted in the valve cylinder 5 The other end is set corresponding to one end of the valve core 6 , and one end of the reagent tube 2 is inserted into the open end of the tube cap 3 . The one-way air valve, the pipe cap 3, and the pipe body plug 4 are made of plastic; the reagent tube 2 is preferably a glass tube; the breath sampling bag 1 can be a plastic bag with a rated volume, It is convenient to accurately detect the alcohol content of gas per unit volume. These materials are all common materials, and the production cost is low....

Embodiment 2

[0039] The difference between this embodiment and embodiment 1 mainly lies in: as figure 2 As shown, it includes two tube caps 3, and the two ends of the reagent tube 2 are respectively inserted into the opening ends of the two tube caps 3, so as to facilitate piercing the sealing layer 18.

Abstract

The invention provides an expiratory alcohol concentration test device for a human body, which comprises an expiratory sampling bag, a one-way air valve, a reagent tube, a pipe cap and two pipe body end sockets. The one-way air valve comprises a valve cylinder and a valve core arranged in the valve cylinder. A valve core baffle is arranged on the inner wall at one end of the valve cylinder, a cone-shaped circular baffle table is arranged on the inner wall in the middle of the valve cylinder, and a cone-shaped circular outer surface which is hermetically matched with the cone-shaped circular inner surface of the cone-shaped circular baffle table is arranged at one end of the valve core. The valve core is located between the one-shaped circular baffle table and the one-shaped circular baffle. The cone-shaped circular outer surface is arranged corresponding to the cone-shaped circular inner surface of the cone-shaped circular baffle table. The expiratory alcohol concentration test device for a human body has the advantages of accuracy in detection, hermetic storage of the detection reagent, convenience in judgment and use, and low cost.

Description

technical field [0001] The invention relates to an alcohol concentration testing tool, in particular to a human breath alcohol concentration testing device. Background technique [0002] Drunk driving can easily lead to traffic accidents, so alcohol testing for drivers is very necessary. At present, the on-site detection of drunk driving mainly uses breath-type alcohol detectors. However, due to the high price of breath-type alcohol detectors, it cannot be popularized to individuals, and the detection reagents or contacts in this type of alcohol detectors are exposed to the air for a long time and are easily affected by temperature. , Humidity and reduce its detection sensitivity. In addition, other detection methods also have various defects, such as: spectrophotometry needs to dilute the sample, and the pretreatment is cumbersome; gas chromatography has a long measurement time and high detection cost, and is suitable for batch detection; Easily affected by temperature, d...
