Description
Technical field
The present invention relates to technical field of medical equipment, particularly relate to oxygen concentration and air quality management device and using method thereof in a kind of air pressurized cabin.
Background technology
Hyperbaric oxygentherapy is divided into two kinds: a kind of employing oxygen pressure cabin hyperbaric oxygentherapy, only accommodate 1 people's treatment in cabin, use pure oxygen pressurization, existing because of oxygen concentration too high (oxygen concentration needs more than 80%) in cabin, safety hazard (the most on fire) is relatively big, in the less use of national each hospital；Another kind of employing air pressurized cabin hyperbaric oxygentherapy, can accommodate many people and treat simultaneously, use pressurized with compressed air in cabin, patient wears mask oxygen-inspiration, and this kind of method hyperbaric oxygentherapy commonly uses in national each hospital.Hyperbaric oxygentherapy process is divided into pressurization, voltage stabilizing oxygen uptake, decompression three phases, and the pressure period uses compressed air to be allowed to pressure in inputting cabin and raises；Voltage stabilizing oxygen uptake maintains both constant-pressures in referring to cabin, oxygen source provide oxygen to suck for patient in being input into cabin, have 2 fixing ventilation processes in the voltage stabilizing stage, i.e. take the compressed air of equal low discharge to enter and discharge (generally 10 minutes)；Decompression is that pressure in cabin is reduced to normal pressure thus completes therapeutic process.Hyperbaric oxygentherapy process is about 2 hours every time.
At present, the hyperbaric oxygentherapy of air pressurized cabin exists following not enough:
(1) in air pressurized cabin, oxygen concentration is high, there is potential safety hazard.
Specifying according to latest national standards, during hyperbaric oxygentherapy, in air compression chamber, oxygen concentration is less than 23%.Hyperbaric oxygentherapy oxygen inhalation mode in air pressurized cabin is divided into lung formula oxygen supply (being commonly called as two grades of oxygen supplys) and gravity flow oxygen supply (being commonly called as one-level oxygen supply), and two grades of oxygen supply patients must buckle face shield, uses certain work of breathing to carry out suction oxygen；And the oxygen of one-level oxygen supply flows directly into, patient is not required to extra consumption work of breathing.So, during hyperbaric oxygentherapy when face shield is buckled and worn blow-by, or when in cabin, one-level oxygen uses more, in cabin, oxygen concentration will raise rapidly.At present, when in cabin, oxygen concentration raises, processing method is: strengthen compressed air to cabin in the ventilation that carries out, but because of some reason following, in cabin, to raise phenomenon more universal for oxygen concentration, and in ventilation rear deck, oxygen concentration decline is the most inconspicuous.
1. in existing current hyperbaric oxygentherapy, stupor, tracheotomy, restless patient get more and more, it can only use one-level offering oxygen way, and its corresponding oxygen absorption mask button is worn blow-by or must take off in face shield (needing suction sputum, cough etc.) etc. causes oxygen to flow into cabin too much without corresponding face shield (tracheotomy, child patient etc.) or centre.
2. being malleation in face shield during patient expiration, face shield is prone to blow-by, causes expired gas to enter in cabin, and in exhaled gas, oxygen concentration also may be up to more than 50%.
3. one-level oxygen supply is light, and oxygen absorbed is big, and patient and medical worker are all ready to use.
4., when in hyperbaric oxygentherapy cabin, oxygen concentration raises, ventilation flow can not excessive (easily causing pressure transient, variations in temperature etc. in cabin).
5. in air, oxygen concentration is 20.9%, differs little with national Specification in air pressurized cabin less than 23%.
Certainly, in cabin, oxygen concentration rising potential safety hazard also increases.For this phenomenon, current each hospital hyperbaric oxygen is taked stronger ventilation amount more, is reduced treatment sufferer or critical sufferer, reduce oxygen flow input etc., but these all can not obtain and reduce the effect of oxygen concentration in cabin very well, and be also unfavorable for treatment and the hyperbaric oxygen clinical practice of sufferer.
(2) stuffy in air pressurized cabin, easily there is hospital infection.
The hyperbaric oxygentherapy of air pressurized cabin belongs to many people and treats simultaneously, and existing current air pressurized cabin is 6 people～50 people's seats, as included entourage and medical personnel, during the internal therapy of cabin up to 10 people to 80 people about.Hyperbaric oxygentherapy is closed environment, and volume of compartment is only 3m per capita3～4m3, and treatment time reach 2 hours.Difference is all had cabin internal therapy conditions of patients weight, sick kind.When hyperbaric oxygentherapy, the most after the treatment when phase and decompression, personnel's sweat evaporation, exhaled gas, patient's cough and suction sputum in cabin, and hyperbaric oxygentherapy decompression phase rule of operation do not have the reasons such as ventilation to cause cabin in air the most muddy, in addition the factor such as variations in temperature in hyperbaric oxygentherapy adds decompression process cabin, in cabin, easily there is flu, cross infection etc. between respiratory tract infection and pneumonia or sufferer in weak person.
Because above-mentioned defect, the present inventor's the most in addition research and innovation, to founding oxygen concentration and air quality management device and using method thereof in a kind of novel air pressurized cabin so that it is have more the value in industry.

9. oxygen concentration and the using method of air quality management device in the air pressurized cabin according to any one of claim 1-8, it is characterised in that the method includes:
Step S1, the oxygen concentration controlled by described Intelligent microelectronic control system in gaseous mass concentration monitoring system detection air pressurized cabin, when described oxygen concentration rises to over the oxygen concentration of national Specification, start molecular sieve oxygen nitrogen piece-rate system by Intelligent microelectronic control system；
Step S2, by described molecular sieve oxygen nitrogen piece-rate system, oxygen and nitrogen are drawn and isolated to the gas in described air pressurized cabin；
After step S3, described isolated oxygen are by the filtration of oxygen reutilization system, supercharging and purification, make described oxygen meet medical oxygen quality standard, the oxygen meeting medical oxygen quality standard is introduced in oxygen source, to be again passed through in described air pressurized cabin；
After described isolated nitrogen is by the filtration of nitrogen reutilization system, supercharging and purification, enter in buffering gas tank, now, the compressed air in air accumulator is introduced by gaseous mass concentration monitoring system, the oxygen concentration of gas in buffering gas tank is controlled 19%, again the gas in buffering gas tank is inputted in described air pressurized cabin, in order to the gas in displaced air compression chamber；
Step S4, repetition step S1～S3, during until oxygen concentration in the air pressurized cabin detected by described gaseous mass concentration monitoring system is less than the oxygen concentration of national Specification, stopped the operation of molecular sieve oxygen nitrogen piece-rate system by described Intelligent microelectronic control system；
Step S5, the air quality in gaseous mass concentration monitoring system detection air pressurized cabin is controlled by described Intelligent microelectronic control system, when described air quality exceedes standard with fresh air, air quality refreshing system is started by Intelligent microelectronic control system, described air quality refreshing system air to external world carries out purifying and after pressurized treatments, by clean compressed air in described air accumulator enters air pressurized cabin, in order to update air in described air pressurized cabin, and pressure raises in the air pressurized cabin hyperbaric oxygentherapy pressure period makes described air pressurized cabin；
Step S6, repeat step S5, during until the air quality in the air pressurized cabin detected by described gaseous mass concentration monitoring system reaches standard with fresh air, by the operation of described Intelligent microelectronic control system stopping air quality refreshing system.
