Description
Technical field
The present invention relates to oxygen therapy device technical field, particularly target formula Intelligence Feedback oxygen therapy device.
Background technology
The ratio of long term oxygen therapy is needed to increase year by year in chronic respiratory failure, the main purpose of oxygen therapy improves anoxia and respiratory failure, improve and organize oxygen supply, maintain human body energy metabolism, namely two the large-scale Prospective Clinical researchs carried out as far back as the eighties in last century confirm, chronic obstructive pulmonary disease is called for short patients with COPD and carries out long-term low discharge oxygen therapy, effectively can improve Activity Endurance, quality of life, prolongation life span.The adaptation of current oxygen therapy is just to extend to most chronic respiratory failure, as interstitial lung disease, neuromuscular disease, bronchiectasis etc., the now flow-control of domestic and international adopted oxygen therapeutic method is empirical, namely patient pulse's blood oxygen saturation (SpO2) is detected, adjusted by medical personnel, a given oxygen flow, as 1.5L/min, there is researcher to propose chronic respiratory failure and easily close nocturnal hypoxaemia, 0.5-1L/min should be improved at night, but studies have found that, merge the patients with COPD of hypercapnia, improve night and PH may be caused to decline to the cost of oxygen flow 1L/min, PaCO2 increases, increase the weight of night respiration disorder, even may cause the adverse events such as stupor, as patient respiratory exhaustion is comparatively serious, namely slightly activity oxygen consumption significantly increases, improve 1L/min not enough again, therefore real-time adjustment cannot be accomplished, it is one of maximum drawback of conventional oxygen therapy.
Because the physiological situation of patient changes at any time, as activity, feed, during defecation, oxygen consumption increases, adjustment deficiency makes hypoxemia continue, tissue is for hypoxgia, have a strong impact on patient activity's endurance, when some patients nighttime sleep, empirically heighten oxygen flow, during different sleep stage, oxygen consumes, respiratory muscle function is different, oxygen supply underfed is easily caused in fast quick-action eye phase and REM phase, affect the curative effect of oxygen therapy, long-term nocturnal hypoxaemia also can promote that the complication such as pulmonary hypertension and pulmonary heart disease occurs, for the patients with COPD merging hypercapnia, the too high respiratory center that may suppress of oxygen therapy flow at night is to the sensitivity of anoxia, suppress patient's autonomous respiration, thus cause serious nitrogen dioxide retention, the adverse events such as stupor may be caused, therefore if realize intelligent feedback control, target setting oxygen saturation, the flow of oxygen therapy is controlled in real time with computer program, oxygen saturation is controlled in desirable level, to contribute to improving oxygen therapy efficiency, reduce the generation of complication, really realize control oxygen therapy.The nineties in last century, Chaout etc. proposed above-mentioned imagination, because the precision of oxygen saturation probe is limited, can not realize precision controlling, and microprocessor not extensive use, finally failed to realize.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the present invention is to provide target formula Intelligence Feedback oxygen therapy device, efficiently solve existing oxygen therapy device cannot Real-Time Monitoring, adjustment and the inefficient problem of oxygen therapy.

Setting minimum oxygen saturation is 80%, and the highest oxygen saturation is 95%, during different blood oxygen saturation, and the difference of oxygen supply oxygen flow:
(1) blood oxygen saturation of patient is lower than 80%, and start oxygen therapy device, now oxygen flow gives maximum 5L/min;
(2), when the blood oxygen saturation of patient is between 80% and 95%, start oxygen therapy device, now oxygen flow gives 3.5L/min;
(3) patient blood oxygen saturation more than 95% time, start oxygen therapy device, now oxygen-supplying amount reduces gradually.
When patient's blood oxygen saturation is lower than 80%, oxygen supply switch is all opened, to provide maximum oxygen-supplying amount 5L/min, speaker B1 sends emergency alarm sound; If with maximum oxygen-supplying amount 5L/min oxygen supply after 2 minutes, the blood oxygen levels of patient is still in minimum oxygen saturation less than 80%, now patient is critically ill, the prompting that speaker B1 sends " please seek medical advice ", LCD display system flickering display " please be sought medical advice " printed words, if patient's blood oxygen saturation rises to minimum oxygen saturation 80% in two minutes, still with maximum oxygen-supplying amount 5L/min oxygen supply, cancel and reporting to the police;
When the blood oxygen saturation of patient is between minimum oxygen saturation 80% and the highest oxygen saturation 95%, target formula Intelligence Feedback oxygen therapy device, with oxygen-supplying amount 3.5L/min, does not do any prompting and warning;
When through oxygen therapy, after the blood oxygen saturation of patient slowly rises to maximum oxygen saturation more than 95%, now oxygen therapy device starts slowly to reduce oxygen-supplying amount, if blood oxygen amount is still more than 95% in the process reducing oxygen-supplying amount, it is standby that oxygen-supplying amount can continue slowly to be reduced to oxygen therapy device, not lower than the highest oxygen saturation 95% in standby rear half an hour, " your blood oxygen saturation is normal in voice message, as left, please shut down ", after not shutting down 30 minutes, voice message " enters holding state ", also as voice message after not shutting down 30 minutes " enters holding state, please shut down as left ", if in the process reducing oxygen-supplying amount, patient's blood oxygen saturation is reduced to less than 95%, and now according to the amplitude reduced, oxygen therapy device increases oxygen-supplying amount automatically, namely realize the automatic adjustment of oxygen-supplying amount according to the change of blood sample saturation, make to maintain more than 95% all the time for blood oxygen saturation,
After patient's blood oxygen saturation remains on more than 95% one hour, when blood oxygen saturation becomes suddenly 0, after acquiescence patient completes oxygen therapy, forget pass oxygen therapy device, now, oxygen therapy device automatic shutdown.
The present invention accepts the change of respiratory failure oxygen flow in real time by high precision oxygen saturation induction apparatus, controlled actual in oxygen flow by microcomputer program, final oxygen saturation is made to maintain normal level, ensure that the effect of oxygen therapy, reach Real-Time Monitoring, adjustment, improve oxygen therapy efficiency, be provided with warning function simultaneously, the safety of guarantee oxygen.
