Abstract
The utility model belongs to the field of air sampling, and particularly relates to an air collection bag of a one-way valve, and the air collection bag comprises a rubber bag, wherein the rubber bag is provided with a rubber bag opening, the rubber bag opening is provided with a one-way valve, and the air exhaled by people can be conveniently and rapidly collected through the one-way valve; and moreover, simplicity for the butt-joint with an alcohol test pipe can be realized, so that whether the alcohol content in the human body is out of limits or not can be detected.
Description
Technical field
The utility model belongs to the gas sample field, relates in particular to a kind of one-way cock gas production bag.
Background technology
At present, exist the multiple gases sampling method, most methods only is confined to, and exists at sampling spot under the sampling condition of pressure to carry out, and utilizes the intrinsic pressure in sampling spot place, and the pressure differential of formation directly forces gas to be pressed in the sample apparatus.But in sampling spot and the extraneous situation that does not have pressure reduction, taking a sample, then not have good way, especially when institute's sample thief be inflammable and explosive or during with the gas of penetrating odor, the personnel's that take a sample safety also can be subject to threat to a certain degree.
Here we introduce a kind of one-way cock gas production bag, the one-way cock gas production bag complex structure of prior art, and practicality is not strong, but also is not used for the one-way cock gas production bag that whether alcohol content exceeds standard in the alcohol detecting test tube human body.
The utility model content
The purpose of this utility model is: for the deficiencies in the prior art, and provide a kind of convenient and practical, be used for the one-way cock gas production bag that whether alcohol content exceeds standard in the alcohol detecting test tube human body.
For achieving the above object, the utility model adopts following technical scheme: one-way cock gas production bag, comprise poly-bag, and described poly-bag is provided with the poly-bag mouth, and described poly-bag mouth is provided with one-way cock.
As a kind of improvement of one-way cock gas production bag described in the utility model, described one-way cock comprises the first accessory and the second accessory, and described the first accessory is provided with through hole, and described the second accessory cooperates with described via clearance.
As a kind of improvement of one-way cock gas production bag described in the utility model, described the first accessory is provided with two sealing wires and two welding and extends the position of bone, two described sealing wires and two described welding extend the position of bone all with described poly-bag welding.
As a kind of improvement of one-way cock gas production bag described in the utility model, the shape of described the second accessory is set to taper.
As a kind of improvement of one-way cock gas production bag described in the utility model, described poly-bag mouth is connected with the alcohol detecting test tube.
The beneficial effects of the utility model are: the utility model comprises poly-bag, described poly-bag is provided with the poly-bag mouth, described poly-bag mouth is provided with one-way cock, the gas that can gather quickly and easily characteristics of contaminated respiratory droplets that arranges by one-way cock, and simple with the docking operation of alcohol detecting test tube, thereby realized whether alcohol content exceeds standard in the human body.

Fig. 1 is cross-sectional view of the present utility model.
Fig. 2 is the structural representation of the one-way cock of Fig. 1.
Fig. 3 is Fig. 1 local first enlarged drawing of poly-bag mouth when blowing.
Fig. 4 is Fig. 1 local the second enlarged drawing of rear poly-bag mouth of blowing.
Embodiment
Below in conjunction with embodiment and Figure of description, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Shown in Fig. 1-4, one-way cock gas production bag comprises poly-bag 1, and poly-bag is provided with poly-bag mouth 2, and poly-bag mouth 2 is provided with one-way cock 3.
The utility model needs to support the use with the alcohol detecting test tube, mode with hot pressing is welding together poly-bag 1 periphery, the size of hot pressing upper/lower die need be controlled well, the capacity that makes poly-bag 1 is 1000 ± 100ML, poly-bag mouth 2 is provided with one-way cock 3, the rear gas of blowing toward poly-bag 1 the inside can not flow out, and plays the gas storage effect, gathers the human body expiration and is mainly used in the alcohol concentration test.
Preferably, one-way cock 3 comprises that the first accessory 4 and the second accessory 5, the first accessories 4 are provided with through hole 8, the second accessories 5 and through hole 8 clearance fit.
Preferably, the first accessory 4 be provided with two sealing wires 6 and two welding extend 7, two sealing wires 6 of the position of bone and two welding extend the position of bone 7 all with poly-bag 1 welding, welding does not have gas leakage like this, must grasp heat pressing process during operation.
Preferably, the shape of the second accessory 5 is set to taper, and the air-flow during air blowing is washed the second accessory 5 open, and air-flow can enter poly-bag 1, blow full gas after poly-bag 1 internal gas pressure make the periphery of the second accessory 5 withstand the first accessory 4 inner via holes 8, reach envelope gas effect.
Preferably, poly-bag mouth 2 is connected with the alcohol detecting test tube so that poly-bag 1 is with after the alcohol detecting test tube is connected, with gas extrusion in testing tube, testing tube accurately in the human body alcohol content whether exceed standard, whether can safe driving.
The according to the above description announcement of book and instruction, the utility model those skilled in the art can also change and revise above-mentioned embodiment.Therefore, the utility model is not limited to above-mentioned embodiment, and any apparent improvement, replacement or modification that every those skilled in the art have done on basis of the present utility model all belong to protection domain of the present utility model.In addition, although used some specific terms in this instructions, these terms do not consist of any restriction to the utility model just for convenience of description.
