The invention aims to provide the expiratory air condensed liquid collecting device which is simple in structure and convenient to operate. The expiratory air condensed liquid collecting device has the advantages that the flexible sealing piece covers the opening in the upper end of the outer pipe; the central part of the flexible sealing piece is fixedly connected to the inner pipe; the flexible sealing piece can ensure stable air pressure in the outer pipe, facilitates air blowing, and can also prevent external air from entering the pipes to interfere with a collecting result.
Description
Technical field
The present invention relates to medical instruments field, particularly a kind of breathe-out air condensate gathering-device.
Background technology
Containing Multiple components in exhaled breath condensate (EBC), comprise little molecule, protein and DNA.By measuring the existence of these compositions or quantity in the exhaled breath condensate of patient, it is possible to provide diagnosis and out of Memory, comprise pH, comprise anti-inflammatory or the existence of various protein of pro-inflammatory cytokine etc..
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, it is simple to the breathe-out air condensate gathering-device of operation.
The purpose of the present invention is achieved through the following technical solutions: a kind of breathe-out air condensate gathering-device, it includes the interior pipe for containing condensed fluid and is set in the outer tube outside interior pipe；Described outer tube upper end open, lower end is connected to liquid and collects lid, and offers inflatable mouth on the downside of outer tube on tube wall；Described outer tube upper end open is coated with flexible cap liner, and the middle part of flexible cap liner is fixedly connected on interior pipe.
Compared to prior art, it is an advantage of the current invention that:
1. outer tube upper end open is coated with flexible cap liner, and the middle part of flexible cap liner is fixedly connected on interior pipe, and flexible cap liner both can ensure that outer intraductal atmospheric pressure was stable, it is simple to blows, and can effectively prevent again ambient atmos from entering in pipe, and result is collected in interference.
2. in, the outside tube wall of pipe is equipped with some spacers, and the outer end of described spacer is resisted against on the inner side tube wall of outer tube.Spacer both ensure that and left enough spaces between inner and outer tubes for the accommodating gas being blown into, and makes again the position of the relative outer tube of interior pipe fix, will not tilt.

Detailed description of the invention
Below in conjunction with Figure of description and embodiment, present invention is described in detail:
It is the embodiment schematic diagram of a kind of breathe-out air condensate gathering-device provided by the invention as shown in Figures 1 to 4.
A kind of breathe-out air condensate gathering-device, it includes the interior pipe 1 for containing condensed fluid and is set in the outer tube 2 outside interior pipe 1；Described outer tube 2 upper end open, lower end is connected to liquid and collects lid 3, and offers inflatable mouth 2-1 on the downside of outer tube 2 on tube wall；Described outer tube 2 upper end open is coated with flexible cap liner 4, and the middle part of flexible cap liner 4 is fixedly connected on interior pipe 1.
Said inner tube 1 includes containing pipe 1-1 and being connected to the sealing lid 1-2 containing pipe 1-1 upper orifice place.
Contain and connected by helicitic texture between pipe 1-1 and sealing lid 1-2.After splendid attire pipe 1-1 fills water, cover formation with sealing lid 1-2 and close space, then place it in frost in refrigerator-freezer, be the formation of for the condensing tube that gas condenses rapidly will be breathed out.
The described upper side sealing lid 1-2 is provided with fixing bar 5, and the upper end of fixing bar 5 is provided with snap ring 5-1；Offer, in the middle part of described flexible cap liner 4, the through hole 4-1 holding fixing bar 5 traverse.
The area of described flexible cap liner 4 is more than the area of outer tube 2 upper end open.
Flexible cap liner 4 is when original state, the upper end open place of outer tube 2 can be fitted under gravity, ambient atmos will not be entered in pipe, when personnel to be detected are to air blowing in outer tube 2, gas in outer tube 2 increases gradually, when air pressure reaches to a certain degree, the edge of flexible cap liner 4 can upwards be backed down by the air-flow risen, unnecessary gas just discharges between the mouth of pipe and flexible cap liner 4, when outer tube 2 internal gas pressure is reduced to a certain degree, flexible cap liner 4 restores to the original state at once, it is prevented that ambient atmos enters in pipe, and result is collected in interference.
Described flexible cap liner 4 is sheet rubber.
The outside tube wall of said inner tube 1 is equipped with some spacer 1-3, and the outer end of described spacer 1-3 is resisted against on the inner side tube wall of outer tube 2.Spacer 1-3 both ensure that and left enough spaces between interior pipe 1 and outer tube 2 for the accommodating gas being blown into, and makes again the position of the interior relative outer tube 2 of pipe 1 fix, will not tilt.
Described liquid is collected lid 3 and outer tube 2 lower end and is connected by helicitic texture is fixing.
Described inflatable mouth 2-1 is the tubular structure extended outside outer tube 2, and described inflatable mouth 2-1 is also arranged with rubber sleeve.
Using method:
Being loaded by water contains in pipe 1-1, screwing hermetic lid 1-2；Interior pipe 1 is inserted in outer tube 2, wraps outer tube 2 with plastic bag and put in refrigerator-freezer freezing；Take out after the water freezing that interior pipe 1 contains, remove plastic bag, blown in outer tube 2 by inflatable mouth 2-1；When liquid collection lid 3 collects abundant exhaled breath condensate, liquid is collected lid 3 and outwards winding, send to detection.
