Detailed description of the invention
The structure of the disposable breath condensate collection device of the present embodiment as shown in Figure 1, comprises the collecting condensation cylinder 2 of valve 1, both ends open.
Vent plug 3 and Non-return air valve 4 is provided with in collecting condensation cylinder 2.The lower ending opening of collecting condensation cylinder 2 is sealed by Non-return air valve 4.Non-return air valve 4 blows out from the lower ending opening of collecting condensation cylinder 2 for preventing gas.Vent plug 3 is positioned at above Non-return air valve 4.
Vent plug 3 is made up of flexible glue material, inner hollow, and top is provided with opening 31, and the space of vent plug 3 upper and lower part is communicated with by opening 31.Vent plug 3 bottom margin is connected with the inner wall sealing of collecting condensation cylinder 2, reinforcement 32 is provided with above bottom margin, for strengthening the stability of vent plug 3 polycrystalline substance, prevent in the process upwards pushed away by collecting condensation cylinder 2 bottom by vent plug 3 at collecting condensation, the situation causing condensate to leak hunting because of vent plug 3 deformation occurs.Between vent plug 3 top and collecting condensation cylinder 2 inwall, there is gap, to form the cavity for collecting condensate in collecting condensation cylinder 2 periphery.Vent plug 3 upwards shrinks gradually from bottom, and the linear opening 31 closing up when forming a naturalness, open when exhaling, as shown in Figure 3, this structure is conducive to preventing air-flow from refluxing from the opening 31 of vent plug 3 further.The linear opening 31 of vent plug 3 has an aperture 33, the diameter of aperture, at about 1mm, for preventing linear opening 31 both sides adhesion, makes linear opening 31 be easier to open when exhaling.
As shown in Figure 1, 2, valve 1 is communicated with from the inside of the barrel between vent plug 3 with Non-return air valve 4 with collecting condensation cylinder 2.The outlet side of valve 1 is higher than the inlet end of valve 1, the gas of exhalation is made to have the speed tilted upward, to make gas can more smoothly by vent plug 3, reduce the condensate between vent plug 3 and Non-return air valve 4, reduce the waste of condensate, be conducive to the speed accelerating breath collecting condensation.The downward-sloping angle of valve 1 is recommended as 30 ° ~ 45 °.The outlet side of valve 1 protrudes from the inwall of collecting condensation cylinder 2, and is no more than the axis of collecting condensation cylinder 2, and the condensate of anti-backflow enters in valve 1.Valve 1 is socketed to form by two sections of bodys itself, and leading portion body and collecting condensation cylinder 2 are connected as a single entity, and back segment body inlet end is flat, and mouth of being more convenient for contains expiration.
Collecting condensation cylinder 2 is socketed to form up and down by three pipeline sections, as shown in Figure 1, vent plug 3 is arranged in different pipeline sections from valve 1, to detach vent plug 3 place pipeline section, thus this pipeline section is enclosed within an apical axis, by apical axis, vent plug 3 is pushed up to the upper end open place near collecting condensation cylinder 2, thus conveniently carry out the collection work of condensate.Non-return air valve 4 and valve 1 are also positioned at the different pipeline section of collecting condensation cylinder 2, so that the assembling of Non-return air valve 4.
Condensate collection device of the present utility model is made up of medical grade rubber and/or medical plastic, and cost is lower, single use, be conducive to the sanitary condition better controlling condensate collection device, and volume is little, lightweight, is easy to carry.
Use the process of the condensate in condensate collection device of the present utility model collection human body breath as follows: pinch or clamp the nose, mouth contains valve 1 and exhales or air-breathing: during expiration, gas enters collecting condensation cylinder 2 upper space by vent plug 3, collecting condensation cylinder 2 top is inserted in a condensation sleeve, condensation sleeve is placed in low temperature environment, the pre-cold reflux of aqueous vapor in gas, is gathered in the collecting condensation cavity between vent plug 3 top and collecting condensation cylinder 2 inwall; During air-breathing, air-flow is entered by Non-return air valve 4; After completing collecting condensation, detach vent plug 3 place pipeline section, this pipeline section is sleeved on an apical axis, utilize this apical axis by the tube port position of vent plug 3 overhead this section of collecting condensation cylinder, dropper etc. can be adopted to gather condensate, after completing condensate sample collection, can directly this condensate collection device be abandoned in hospital waste bucket.
