Abstract
The expiring and inspiring flow rate testing instrument is used in the technological field of clinical medicine and is developed based on the four breathing mode theory of the present inventor. ARDS pulmonary edema is caused by increased negative pressure in pulmonary tissue owing to continuous excessive exhaust of alveolus resulting in reduced alveolus volume. The expiring and inspiring flow rate testing instrument designed based on the said theory is used in early diagnosis of ARDS. It is simple in structure, easy in operate and fast and accurate in test and harmless to the tested body. It is used in early diagnosis of ARDS to direct the regulation of respiratory machine.
Description
Field: clinical diagnose instrument
Background technology: pulmonary function instrument and respirator just detect inspiration capacity, pulmonary function can only detect the tolerance of an aspiratory action, and respirator is not that inspiration capacity is detected, but to the setting of air inflow, anesthetic machine also can be monitored tidal volume, but be the mensuration of individual event process, rather than to breathing the mensuration of reciprocal process.The people at respiratory because the carbon dioxide of the oxygen of the different needs of depleting substance and generation is also different, respiratory quotient difference just, his decider's inspiration capacity and expiration amount different, this difference has a constant volume limit under the physiological condition, surpassing this limit and continue such breathing pattern people and will enter pathological process, is theoretical according to Yao's four kinds of respiratory membranes that bundle proposes of fighting:
First kind: it is our the longest breathing pattern of persistent period in life that per minute sucks this pattern of tolerance-expiratory gas volume=50ml.
Second kind: per minute sucks this pattern of tolerance-expiratory gas volume＜50ml to be interrupted once in a while in life at us and to adopt, as blow up a balloon, sing, acutely cough, wail, the sample breathing etc. of breathing out during pain.
The third: per minute sucks this pattern of tolerance-expiratory gas volume＞50ml to be interrupted once in a while in life to adopt at us and manyly to take place together with second pattern, as sob, yawn, violent dark air-breathing or the like before the cough.
The 4th kind: this pattern of per minute suction tolerance-expiratory gas volume=0ml occurs in to decompose sugar not long for the following persistent period of condition of main energy supply material, hurries up as short distance.
If human body employing second or three kind of breathing pattern also continue for some time, will change the gas volume in the lung, also just can cause corresponding pathological process.Expiratory gas volume makes alveolar volume reduce 1/3-1/2 will cause ARDS.The ARDS pulmonary edema is to continue by long-time that gas is excluded in the Hyperventilation alveolar, and alveolar volume reduces to cause that negative pressure increases institute extremely between lung tissue, and it is the cause of disease that alveolar volume reduces, and pulmonary interstitial edema is the result.Air-breathing expiratory gas flow detector is exactly the early diagnosis ARDS instrument according to this Design Theory.
Summary of the invention:
1, technical problem: according to four kinds of breathing pattern theories, we can be by sucking with the difference early discovery of expired gas and diagnosing ARDS, this prevention and treatment to this disease is all significant, though because have respirator can accurately set suction tolerance at present, the pulmonary function instrument can detect and once suck and the tolerance of breathing out, anesthetic machine also can be monitored tidal volume, but the while dynamic acquisition sucked the accurate numerical value of tolerance and expiratory gas volume in various instruments all can't be finished at one time, our the air-breathing expiratory gas flow detector of invention is exactly effectively to address these problems, finish accurate mensuration, and in time be prompted to the clinician suction tolerance and expiratory gas volume.
2, technical scheme: so unequal according to respiratory quotient normal mean value 0.8 inspiration capacity and expiratory gas volume, as the difference of difference less than the output of oxygen and carbon dioxide in the respiratory quotient, just illustrate that expiratory gas volume is too much, just cause the danger of ARDS again, around this principle, gas flowmeter with precision sucks the gas flow and the expired gas scale of construction at the unit interval record accurately, and parameter is imported data center's processing system, by the digital display screen reflection dynamic data of calculating instrument.By monitor and meter record paper accurate recording, instrument provides early warning to show according to setting value and reports to the police, to determine whether ARDS takes place.
3, beneficial effect: (1) instrument and equipment is simple in structure, processing ease and testing result quick and precisely is provided.(2) detection is harmless.(3) can early diagnosis ARDS.(4) instruct regulation and control breathing machine ventilation amount.(5) fundamentally solve present ARDS and just be difficult to the passive situation of giving treatment to once clinical diagnosis.
