Acquisition method and its device.
Background technique
Oxygen therapy main purpose is to correct the hypoxemia of human body, reduces work of breathing and lightening heart load, prevents
With reverse anoxic caused by tissue damage and organ dysfunction, while as far as possible keep patient mobility.Oxygen therapy
Principal risk is effectively correct hypoxemia, aggravates carbon dioxide retention or even oxygen poisoning etc..The oxygen therapy of specification
Principle is to ensure that its safely, effectively property.Domestic oxygen can be clearly proved there are two famous controlled clinical trial in the world
The validity for the treatment of and corresponding condition, while being also that many national treat domestic oxygen are included in national health security system
Scientific basis.
In the 1970's, National Institutes of Health (NIH) night oxygen therapy tests (NOTT) and British Medical studies committee member
Meeting clinical test (MRC) is studies have shown that the improvement of the COPD patient five-year survival rate of chronic hypoxemia and daily oxygen therapy are held
Continuous time (hour) is directly proportional.Survival without complementary oxygen therapy is worst；It is small to receive 12 to 15 daily
When oxygen therapy the survival rate of patient be preferable；Receive the survival of the mobile intimate 24 hours duration oxygen therapies of oxygen system
It is best.
American Thoracic Society (ATS), European pneumatology meeting (ERS), the state-run health of Britain and clinical optimizing research institute
(NICE) etc. the prescription standard and therapeutic purpose of home oxygen therapy have clearly been formulated in the treatment guidelines of country.Chinese medicine class
Oxygen therapy indication and indication are also included in " clinical practice " teaching material, the core content and American Thoracic of various countries' guide by authoritative teaching material
It is similar to learn the standard that (ATS) is formulated.Stabilization after occurring hypoxemia or COPD acute exacerbation in COPD progression of disease
Phase arterial partial pressure of oxygen PaO2< 55mmHg or arterial oxygen saturation SaO2< 88% or arterial partial pressure of oxygen PaO2=55-
59mmHg and with cor pulmonale, polycythemia, pulmonary hypertension etc..Therapeutic purpose: when tranquillization, sleep, activity
All guarantee PaO2>60mmHg(SaO2> 90%), daily oxygen time was 15 hours or more, it is therefore desirable at 18-24 hours.
Shown in terms of compliance and therapeutic effect according to pertinent literature both domestic and external, oxygen therapy quality management means
Generally compare shortage, monitoring effect is poor.Be mainly manifested in: patient whether oxygen uptake, oxygen time how long, flow is how many, is
It is no how to follow doctor's advice, patient's oxygen absorben effect (blood oxygen saturation, respiratory rate, symptom improvement, the state of mind, appetite etc.)
The present invention in view of the above-mentioned problems, emphasis solve whether the real-time monitoring of oxygen uptake, oxygen time and respiratory rate etc.
Problem.There is clinical research to show that COPD acute attack can be effectively predicted in the variability monitoring of respiratory rate, especially to do early
It is pre- that effective means is provided.
EUROPEAN PATENT OFFICE's patent No. of French SRETT company application: EP3146 897A1, a kind of technology is for solving in nose
The problem of respiratory rate and oxygen flow measure is judged during conduit oxygen uptake, the scheme proposed is two MEMS Mikes
Wind, a MEMS pressure sensor and an ambient pressure sensor, in conjunction with a kind of resistance with Fluid Mechanics Computation (CFD)
Flow structure obtains the respiratory rate and suction of patient with difference channel, filter circuit, respiratory rate, flow rate calculation circuit etc.
Oxygen flow.
The program has the disadvantage that 1, because pressure change signal caused by breathing is faint, needs the sensor of selection
Meet high-precision requirement；2, because sampling calculation amount is bigger and device is by energy saving demand, to main control singlechip
(MCPU) or the type selecting demand of dsp processor is higher；3, above-mentioned factor 1,2 will lead to increased costs, be unfavorable for promoting and applying.
