Description
Technical field
The present invention relates to oxygen concentration and air quality pipe in technical field of medical equipment, more particularly to a kind of air pressurized cabin
Manage device and its application method.
Background technology
Hyperbaric oxygentherapy is divided into two kinds：One kind, which is used, only accommodates 1 people treatment in oxygen pressure cabin hyperbaric oxygentherapy, cabin, adopt
Pressurizeed with pure oxygen, now because in cabin oxygen concentration it is too high (oxygen concentration need more than 80%), safety hazard (easily on fire) is larger, in the whole nation
Each hospital is less to be used；Another use air pressurized cabin hyperbaric oxygentherapy, cabin interior energy accommodates many people and treated simultaneously, uses compression
Air pressurized, patient wears mask oxygen-inspiration, and such a method hyperbaric oxygentherapy is generally used in national each hospital.Hyperbaric oxygentherapy
Journey is divided into pressurization, voltage stabilizing oxygen uptake, decompression three phases, and the pressure period is inputted in cabin using compressed air and is allowed to pressure rise；Surely
Oxygen uptake is pressed to refer to maintain both constant-pressures in cabin, providing oxygen by oxygen source is input into cabin for patient's suction, there are 2 times in the voltage stabilizing stage admittedly
Determine ventilation process, that is, take the compressed air of equal low discharge to enter and discharge (generally 10 minutes)；Decompression is by cabin
Interior pressure reduces to normal pressure to complete 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) oxygen concentration is high in air pressurized cabin, there is potential safety hazard.
Provided according to latest national standards, oxygen concentration is no more than 23% in air compression chamber during hyperbaric oxygentherapy.Air adds
Ballasting hyperbaric oxygentherapy oxygen inhalation mode 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), two
Level oxygen supply patient must fasten mask, and suction oxygen is carried out using certain work of breathing；And the oxygen of one-level oxygen supply is flowed directly into, patient
It is not required to extra consumption work of breathing.So, during hyperbaric oxygentherapy when mask is buckled and wears blow-by, or in cabin one-level oxygen using more
When, oxygen concentration will be raised rapidly in cabin.At present, when oxygen concentration is raised in cabin, processing method is：Strengthen compressed air to cabin
The ventilation of interior progress, but because of some following reason, oxygen concentration rise phenomenon is more universal in cabin, and in ventilation rear deck
Oxygen concentration declines very unobvious.
1. stupor, tracheotomy, restless patient are more and more in existing current hyperbaric oxygentherapy, it can only use one-level oxygen supply
Mode, and its corresponding oxygen face mask button wears blow-by or without corresponding mask (tracheotomy, child patient etc.) or middle necessary
Removing mask (needing suction sputum, cough etc.) etc. causes oxygen to flow into cabin excessively.
2. being malleation in mask during patient expiration, mask is easy to blow-by, causes expiratory air to be discharged into cabin, and exhaled gas
Middle oxygen concentration also may be up to more than 50%.
3. one-level oxygen supply is easily, oxygen absorbed is big, and patient and medical worker are ready to use.
4. oxygen concentration is raised in hyperbaric oxygentherapy cabin, ventilation flow excessive (can not easily cause pressure instability in cabin
Fixed, temperature change etc.).
5. oxygen concentration is 20.9% in air, differ small no more than 23% with national Specification in air pressurized cabin.
Certainly, oxygen concentration rise potential safety hazard is also increased in cabin.For this phenomenon, current each hospital's hyperbaric oxygen is more
Take stronger ventilation amount, reduce treatment sufferer or critical sufferer, reduce oxygen flow input etc., but these can not all be obtained very well
The effect of oxygen concentration in cabin is reduced, and is also unfavorable for the treatment and hyperbaric oxygen clinical practice of sufferer.
(2) it is stuffy in air pressurized cabin, easily occur hospital infection.
The hyperbaric oxygentherapy of air pressurized cabin belongs to many people and treated simultaneously, now current air pressurized cabin be the people of 6 people~50 seat not
Deng up to 10 people to 80 people or so when such as including treating in entourage and medical personnel, cabin.Hyperbaric oxygentherapy is closed loop
Border, volume of compartment is only 3m per capita3~4m3, and treatment time was up to 2 hours.Conditions of patients weight, disease are treated in cabin difference.
In hyperbaric oxygentherapy, especially phase and during decompression after the treatment, personnel's sweat evaporation, exhaled gas, patient's cough and inhale in cabin
Phlegm, and hyperbaric oxygentherapy decompression phase operational procedure does not have the reasons such as ventilation to cause air in cabin more muddy, it is in addition high
Pressing oxygen therapy to add in decompression process cabin, easily there is flu, respiratory tract infection and pneumonia in weak person in the factor such as temperature change, cabin
Or the cross-infection between sufferer etc..

Method, it is characterised in that this method includes：
Step S1, by the intelligent microelectronic control system gaseous mass concentration monitoring system is controlled to detect in air pressurized cabin
Oxygen concentration, when the oxygen concentration rises to over the oxygen concentration of national Specification, pass through intelligent microelectronic control system
Start molecular sieve oxygen nitrogen piece-rate system；
Step S2, the gas in the air pressurized cabin is drawn by the molecular sieve oxygen nitrogen piece-rate system and oxygen is isolated
And nitrogen；
After step S3, the oxygen isolated are filtered by oxygen reutilization system, be pressurized and purified, meet the oxygen
Medical oxygen quality standard, the oxygen for meeting medical oxygen quality standard is introduced in oxygen source, added with being passed through the air again
In ballasting；
After the nitrogen isolated is filtered by nitrogen reutilization system, be pressurized and purified, into buffering gas tank, now,
The compressed air introduced by gaseous mass concentration monitoring system in air accumulator, the oxygen concentration control for buffering gas in gas tank is existed
19%, then the gas buffered in gas tank is inputted in the air pressurized cabin, to the gas in displaced air compression chamber；
Step S4, repeat step S1~S3, until the air pressurized cabin detected by the gaseous mass concentration monitoring system
When interior oxygen concentration is less than the oxygen concentration of national Specification, molecular sieve oxygen nitrogen is stopped by the intelligent microelectronic control system
The operation of piece-rate system；
Step S5, by the intelligent microelectronic control system gaseous mass concentration monitoring system is controlled to detect in air pressurized cabin
Air quality, when the air quality exceed standard with fresh air when, pass through intelligent microelectronic control system start air matter
Refreshing system is measured, air is carried out after purification and pressurized treatments the air quality refreshing system to external world, and clean compression is empty
Gas is through in the air accumulator air inlet compression chamber, to update air in the air pressurized cabin, and in air pressurized cabin
The hyperbaric oxygentherapy pressure period makes pressure rise in the air pressurized cabin；
Step S6, repeat step S5, up in the air pressurized cabin detected by the gaseous mass concentration monitoring system
When air quality reaches standard with fresh air, stop the fortune of air quality refreshing system by the intelligent microelectronic control system
OK.
