Embodiment one：Breathing sampling bag, including bag body 100 and the air inlet 200 on bag body 100；Bag body 100 is equipped with
For holding the cavity of sample gas, air inlet 200 is connected with cavity, and sampling can be blowed into cavity by air inlet 200
Gas;Bag body 100 by two flaky elastic materials by edge 101 seal it is fixed formed, the cavity is by two sheet like flexible materials
Space between material middle part is formed, and the air inlet 200 is located at the edge 101 of bag body 100, and the sealing of edge 101 is fixed
Hot pressing completion can be carried out by two sheet materials, naturally it is also possible to carried out using other connection modes, as long as its sealing can be realized
Effect, can connect blow tool at air inlet 200 can also directly blow, and blow tool said herein can be
A kind of air blowing funnel, there is the auxiliary section being adapted with people's mouth and connecting tube 202, connecting tube 202 can be carried out with air inlet 200
The quick connection reliably sealed.
In the above-described embodiment, the middle part of bag body 100 is equipped with 100 cavity of bag body every being set as two-part closure band 102,
Two sheet material heat seals of the formation bag body 100 at closure band 102 are bonded and sealed, and block 102 both ends of band and each extend over
To the edge 101 of bag body 100, namely bag body 100 is by blocking band 102 by the cavity of bag body 100 every being set as two parts, still
Closure band 102 is equipped with a notch 103, which is equipped with the interconnecting part 300 of 100 two parts cavity of connection bag body, the company
Logical portion 300 is fabricated from a flexible material, and the closure band 102 is equipped with easy-torn line 104, and forming closure band 102 can along easy-torn line 104
Tear to the structure of interconnecting part 300, each cavity is respectively equipped with air inlet 200, and when use can will block band along easy-torn line 104
102 tear to interconnecting part 300, are then screwed two parts of bag body 100 respectively using the flexible characteristic of interconnecting part 300, shape
100 two parts air sample of bag body is subjected to separated structure into by being screwed at interconnecting part 300 to be formed to seal, thus can
Form two parts CO2The different sample of content, 100 part of bag body being first filled with sample can be detected as priority, and
100 part of bag body being subsequently full of can be detected as aid sample so that testing result is more easy to control.
In one embodiment, a through hole 201 is equipped with the edge 101 of bag body 100 during described air inlet 200, passed through
Heat seal is welded with connecting tube 202 made of a hard material, and 202 inner wall of connecting tube is equipped with elastic made of elastic rubber
Set 203, the resilient sleeve 203 are equipped with the hole connected with connecting tube 202 of frusto-conical, and connecting tube 202 is connected through a screw thread
One lid 204, the inserted link 205 mating with resilient sleeve 203 of an extension, inserted link 205 here are equipped with 204 center of lid
The sealing to gas is formed after the completion of air with resilient sleeve 203, when in addition resilient sleeve 203 can be that inflating funnel coordinates,
Used as the component coordinated with the sealing of connecting tube 202, resilient sleeve 203 is squeezed can form closely with connecting tube 202
Sealing structure, realize sealing effect using its elastic restoring force.
In one embodiment, the interconnecting part 300 includes control pipe 301, the control made of elastic silicone rubber
Pipe 301 is the thicker dumbbell structure in middle thin both ends, and interconnecting part 300 further includes the circle of 100 two parts cavity of a connection bag body
Post holes 302, the pars intermedia of control pipe 301 coordinate with the above-mentioned cylindrical hole 302, and it is different that 301 both ends of control pipe are located at bag body 100

303, cap body 303 is equipped with the aperture connected with cylindrical hole 302 to shrinking at center and thickness is gradually thinning at 303 center of cap body,
Barotropic gas is formed by aperture compressive deformation widened structure during cap body 303, due to being subject to the inhibition of interconnecting part 300,
Its intake velocity of 100 part of bag body of air inlet first will be far longer than 100 intake velocity of another part bag body, when completion is filled first
When 100 part of bag body of gas is full, another part bag body 100 is also almost in shrivelled state, continues inwardly inflation, satisfies at this time
Full 100 partial gas pressure of bag body increase, gas act on cap body 303 by interconnecting part 300, the cap when air pressure reaches a certain level
Body 303 will expand so that strengthen the gas between two bags of 100 parts of body circulation, therefore the thickness of 303 part of cap body as far as possible compared with
It is thin reach the gas sample of shrivelled state in the structure of dilatating and deformable under gas pressure, can be entered at this time largely to exhale just
The gas sample in stage beginning, and the gas in 100 part of bag body being first filled with and the gas sample of new incoming call are formed and replaced, and are reached
The technique effect different to different 100 partial CO 2 contents of bag body, but also follow-up incoming call gas is strengthened by interconnecting part 300
The resistance of body, natural increase the time required to the gas of incoming call unit volume, and then exhaled gas carbon dioxide content is also higher.
Compared with prior art, the utility model is by setting two interconnected cavitys, two cavitys when being inflated,
Since the interconnecting part between two cavitys causes, a cavity is first filled with, and another cavity is then in the situation for subsequently having enough pressure
Under could persistently inflate, when persistently above-mentioned gas replenishment process, due to being subject to the resistance of interconnecting part, exhale and slow down naturally in speed,
Cause the space natural increase that gas stops in lung, and then improve the CO in exhaling2Content.
