The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, this utility model is further elaborated below in conjunction with drawings and Examples.
Main purpose of the present utility model is to provide a kind of gas sampling bag that is applicable to breath test, collects the gas of testee pulmonary exactly in simple mode.
See also Fig. 1, the external structure sketch map of the gas sampling bag of using for breath test in this utility model preferred embodiment.As shown in Figure 1, the gas sampling bag that this utility model provides comprises sampling bag 10, and is located at the blowing nozzle 20 on the described sampling bag 10.Sampling bag 10 is used to hold sample gas, and blowing nozzle 20 is used for blowing for testee.
Please in conjunction with consulting Fig. 2, the ventilative state cutaway view of the gas sampling bag of using for breath test in this utility model preferred embodiment.As shown in Figure 2, be provided with the passage of two separations in the blowing nozzle 20, be respectively inlet channel 21 and outlet passageway 22.In manufacturing process, blowing nozzle 20 and 10 sealings of sampling bag make inlet channel 21 and outlet passageway 22 be communicated with described sampling bag 10.Be provided with gas lid 23 at inlet channel 21 with outside air inlet 211 places, be used to open and seal inlet channel 21.And establish vent plug 24 with outside place, gas outlet at outlet passageway 22, be used to open and seal outlet passageway 22.
Unique distinction of the present utility model is to adopt air inlet and gives vent to anger two passages.In use, testee is at first opened gas lid 23 and vent plug 24, aims at the air inlet 211 of blowing nozzle 20 and blows, and gas is entered by inlet channel 21, makes that the gas in the sampling bag 10 is discharged by outlet passageway 22.Exhale to farthest the time at testee, closed vent plug 24 closes to hold one's breath again and cover 23, thereby with outlet passageway 22 and inlet channel 21 sealings, makes inlet channel 21, sampling bag 10 and outlet passageway 22 constitute confined spaces, with the preservation sample gas.In this way, the surplus waste gas that has in the sampling bag 10, and testee initial breathe out in the mouth with trunnion in gas, can discharge by outlet passageway 22, and the sampling bag 10 last sample gases of gathering are the pulmonary gases that testee is exhaled and breathed out when finishing soon, thereby having guaranteed that the gas sampling bag can collect exactly comes from pulmonary gases, and then improves the precision and the accuracy of breath test.
Further, gas sampling bag of the present utility model can also be set up the accuracy that some technical characterictics improve sampling.As shown in Figure 2, inlet channel 21 bores of gas sampling bag of the present utility model are greater than outlet passageway 22 bores.Can guarantee like this sampler bag gas circulation and have waste gas blow out the bag outside in, can collect enough sample gases.
In addition, as shown in Figure 2, also be provided with airflow duct 11 in the sampling bag 10, airflow duct 11 is socketed on the inner of inlet channel 21, and extends to the inner chamber bottom of sampling bag 10.Make inlet channel 21 extend to certain-length like this, so incoming call gas can enter in the inner chamber bottom of sampling bag 10 by the inlet channel 21 of this extension by this airflow duct 11.In this way, gas in the inlet channel 21 is entered the import of the bag 10 of sampling, discharge the outlet of outlet passageway 22 spatially separates with gas in the sampling bag 10, like this when guaranteeing air inlet and giving vent to anger by different corridor diversions, make the gas in the sampling bag 10 first in first out to circulate, so that enter the pulmonary gases of sampler bag body 10 after collecting at last.
In order to prevent that when exhaling end the gas in the sampler bag is by the air inlet 211 anti-bags that flow out, this utility model is provided with tabletting mechanism 25 at air inlet 211 places of inlet channel 21.For the ease of forming tabletting mechanism, this utility model will be provided with an inflatable mouth circle 251 at air inlet 211 places, and the bore of this inflatable mouth circle 251 is wide at the top and narrow at the bottom.At the following bore place of inflatable mouth circle 251 butt one tabletting circle 252, this tabletting circle 252 has elasticity and downward naturally, and when testee was aimed at the blowing nozzle expiration, gas entered inlet channel 21 by the following bore of inflatable mouth circle 251.And in vent plug 24 closures of testee with outlet passageway 22, after mouth leaves the air inlet 211 of blowing nozzle 20 simultaneously, tabletting circle 252 in sampler bag gas upwards prop up the following bore of inflatable mouth circle 251 under the spontaneous gas pressure, thereby guarantee that the gas in the sampler bag can not overflow.Tabletting mechanism 25 is arranged on the inside of gas lid 23, has further strengthened the effect of gas lid 23, so that inlet channel 21 is sealed.
Please in conjunction with consulting Fig. 3, the closure state cutaway view of the gas sampling bag of using for breath test in this utility model preferred embodiment.As described in Fig. 2 and Fig. 3, the side of the blowing nozzle 20 of gas sampling bag of the present utility model is provided with silica gel hose 26, and this silica gel hose 26 is communicated with outlet passageway 22 with extension outlet passageway 22, and above-mentioned vent plug 24 is located at the place, gas outlet of described silica gel hose 26.Like this, blowing nozzle 20 forms branched shape, and promptly the gas by the upper end covers 23 places incoming call gas, by the vent plug 24 places discharge gas of side bifurcation.In cutaway view, can see the axial setting of inlet channel 21 along blowing nozzle 20, cover the 23 inner chamber bottoms that extend to sampling bag 10 from the gas of upper end.And outlet passageway 22 comprises two sections passages, and wherein first section passage is parallel with inlet channel 21, and second section passage then extends to silica gel hose 26 perpendicular to inlet channel 21.
The operation of testee for convenience, vent plug 24 of the present utility model is provided with radial venthole 241 on sidewall, and is provided with vent plug hole 242 in the axial direction, and an end in vent plug hole 242 is communicated with venthole 241, the other end and silica gel hose 26 internal communication.Therefore, respectively as shown in Figures 2 and 3, when needs are opened vent plug 24, only need vent plug 24 is extracted certain distance, make venthole 241 be communicated with extraneous air, when needs closure vent plug 24, vent plug 24 can be filled in the silica gel hose 26, make venthole 241 match and then closed outlet passageway 22 with silica gel hose 26.
In sum, this utility model adopts air inlet and gives vent to anger two channel-type designs, make from the gas of inlet channel incoming call and discharge from outlet passageway in the mode of first in first out, thereby guaranteed that the gas sampling bag can collect the pulmonary gases of breathing out when testee is exhaled fast the end exactly, and then improved the precision and the accuracy of breath test.And the inlet channel bore is designed to greater than the outlet passageway bore, and assurance gas sampling bag can be collected enough sample gases in gas circulation and when having waste gas to blow out outside the bag.In the sampling bag, add airflow duct in addition, inlet channel is extended to the inner chamber bottom of sampling bag, make on the connected entrance space of inlet channel and outlet passageway and sampling bag and separate, further like this ensured the first in first out in the gas recycle process, made that also the surplus waste gas that has can be discharged smoothly in the bag.Also tabletting mechanism is set simultaneously, to prevent gas reflux at the air inlet place.
This utility model is described according to specific embodiment; but it will be understood by those skilled in the art that when not breaking away from this utility model scope; can carry out various variations and be equal to replacement, any of these changes and is equal in the scope that replacement all falls into this utility model protection.In addition, for adapting to the specific occasion or the material of this utility model technology, also can carry out many modifications and not break away from its protection domain this utility model.Therefore, this utility model is not limited to specific embodiment disclosed herein, and comprises that all drop into the embodiment of claim protection domain.
