Analyze the air breathed out and can indicate some situation and disease, such as, allow experimenter take specifically14After C flag compound, owing to the reason of disease can cause the change of pathways metabolism, one of its change is via the meta-bolites exhaled and discharge14CO2Amount can there is difference. Gather the carbon dioxide in exhaling, measure wherein14The radioactive activity of C, whether diagnosable disease exists and degree.
Such as in Hp detects, by exhaling, card gathers carbon dioxide sample, then analyzes carrying out detection in expiration card insertion Hp detector. Shown in Fig. 1 is existing Hp detector expiration card, in the card 1 blocked of exhaling, circular absorbing sheet 2 is set, and the both sides of absorbing sheet 2 seal respectively, card 1 also arranges indicating window 3, the two ends of card 1 arrange exhalation vents 4 and air outlet 5 respectively, forming gas passage in card 1 between exhalation vents 4 and air outlet 5, wherein absorbing sheet 2 was arranged in gas passage. Due to card 1 in the form of sheets, exhalation vents 4 aperture is little, and experimenter contains exhalation vents 4 and exhales, and experimenter's corners of the mouth place easily leaks gas, it may also be useful to uncomfortable; Experimenter's expiratory duration is long, and indicating window 3 is not easy to reach sampling standard.
Practical novel content
The utility model provides a kind of Hp detector to exhale card, solves and is exhaled card sampling by existing Hp detector, and the experimenter corners of the mouth place that exhales easily leaks gas, and expiratory duration is long, the problem of impact sampling.
The utility model solves the technical scheme that its technical problem adopts: Hp detector is exhaled card, comprise card and absorbing sheet, described card arranges exhalation vents and air outlet respectively, forming gas passage between the exhalation vents of card and air outlet, crossing in gas passage in card arranges described absorbing sheet; The exhalation vents of described card arranges joint, and joint connects valve. Experimenter exhales in exhaling card by valve to Hp detector, can avoid the gas leakage at corners of the mouth place, ensure efficiency and the accuracy of sampling.
Specifically, described valve for sucking valve or uncovered valve, wherein, described in suck valve cross section in oval shape, described uncovered valve is funnel-form.
Moreover, described in suck valve cross section in oval shape, suck valve and increase gradually to the one end away from joint near joint one end.
Further, described card, joint and valve are an entirety. Or, removably connect between the joint of described card and valve. Specifically, it is threaded between described joint and valve.
Further, described absorbing sheet is rounded, and card also arranges indicating window, and described indicating window is arranged between absorbing sheet and joint.
The beneficial effects of the utility model are: exhaling to block by Hp detector gathers carbon dioxide sample, experimenter crosses the absorbing sheet breath in gas passage by valve in card, improve the comfortable property exhaled, and the gas leakage at experimenter's corners of the mouth place can be avoided, ensure that the efficiency of sampling and accuracy.
