Description

Breathe-out air condensate gathering-device

Technical field

This utility model 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 surveying Measure existence or the quantity of these compositions in the exhaled breath condensate of patient, it is possible to provide diagnosis and out of Memory, bag Containing pH, the existence of various protein comprising anti-inflammatory or pro-inflammatory cytokine etc..

Summary of the invention

The purpose of this utility model is to provide a kind of simple in construction, it is simple to the exhaled breath condensate of operation is collected Device.

The purpose of this utility model is achieved through the following technical solutions: a kind of breathe-out air condensate gathering-device, It includes the inner tube for containing condensed fluid and is set in the outer tube outside inner tube；Described outer tube upper end open, Lower end connects has liquid to collect lid, and offers inflatable mouth on the downside of outer tube on tube wall；Described outer tube upper end is opened Mouth is coated with flexible cap liner, and the middle part of flexible cap liner is fixedly connected in inner tube.

For prior art, the utility model has the advantage of:

1. outer tube upper end open is coated with flexible cap liner, and the middle part of flexible cap liner is fixedly connected in inner tube, Flexible cap liner both can ensure that outer intraductal atmospheric pressure was stable, it is simple to blows, can effectively prevent ambient atmos from entering again Entering in pipe, result is collected in interference.

2. the outside tube wall of inner tube is equipped with some spacers, and the outer end of described spacer is resisted against outer tube On the tube wall of inner side.Spacer both ensure that leaving enough spaces between inner and outer tubes was blown into for accommodating Gas, makes again inner tube fix relative to the position of outer tube, will not tilt.

Detailed description of the invention

Below in conjunction with Figure of description and embodiment, this utility model content is described in detail:

The enforcement of a kind of breathe-out air condensate gathering-device provided for this utility model as shown in Figures 1 to 4 Illustrate and be intended to.

A kind of breathe-out air condensate gathering-device, it includes the inner tube 1 for containing condensed fluid and is set in Outer tube 2 outside inner tube 1；Described outer tube 2 upper end open, lower end connects liquid collection lid 3, and outward Inflatable mouth 2-1 is offered on tube wall on the downside of pipe 2；Described outer tube 2 upper end open is coated with flexible cap liner 4, The middle part of flexible cap liner 4 is fixedly connected in inner tube 1.

Said inner tube 1 includes containing pipe 1-1 and being connected to contain the sealing lid 1-2 at pipe 1-1 upper orifice.

Contain and connected by helicitic texture between pipe 1-1 and sealing lid 1-2.After splendid attire pipe 1-1 fills water, With seal lid 1-2 cover formation close space, then place it in refrigerator-freezer freeze, be the formation of for The condensing tube that exhaled gas is condensed rapidly.

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 and hold the through hole 4-1 that fixing bar 5 passes.

The area of described flexible cap liner 4 is more than the area of outer tube 2 upper end open.

Flexible cap liner 4, when original state, can be fitted in the upper end open of outer tube 2 under gravity Place so that ambient atmos will not enter in pipe, when personnel to be detected blow in outer tube 2, in outer tube 2 Gas gradually increase, when air pressure reaches to a certain degree, the air-flow of rising can be by the limit of flexible cap liner 4 Edge upwards backs down, and unnecessary gas just discharges, when in outer tube 2 between the mouth of pipe and flexible cap liner 4 When air pressure reduces to a certain extent, flexible cap liner 4 restores to the original state at once, prevents ambient atmos from entering in pipe, 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 supported Lean against on the inner side tube wall of outer tube 2.Spacer 1-3 both ensure that and left between inner tube 1 and outer tube 2 enough Space for the accommodating gas being blown into, make again the position of the relative outer tube 2 of inner tube 1 fix, will not about 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 also overlaps It is provided with rubber sleeve.

Using method:

Being loaded by water contains in pipe 1-1, screwing hermetic lid 1-2；Inner tube 1 is inserted in outer tube 2, uses plastics Bag is wrapped outer tube 2 and puts in refrigerator-freezer freezing；Take out after the water freezing that inner tube 1 contains, remove plastic bag, Blown in outer tube 2 by inflatable mouth 2-1；Treat that liquid is collected lid 3 and collected abundant expired gas condensation During liquid, liquid is collected lid 3 and outwards winding, send to detection.
