Description
Technical field
The present invention relates to a kind of oxygen therapy gas and vapor permeation humidification device, particularly relate to a kind of in oxygen inhalation therapy process, can regulate and the device that the humidifying rate (humidity) of mist is regulated the mixing ratio of oxygen and air.
Background technology
Oxygen therapy, a kind of Therapeutic Method of the breathable gas higher than oxygen content in normal air provided for patient exactly, object being oxygenate ability for improving hemoglobin, increasing blood oxygen concentration, improving tissue metabolism, promoting that tissue repair and reconstruction etc. play a role; Oxygen therapy, normally with machinery (atomization, humidifying, the higher-order of oscillation etc.) mode, by certain density oxygen delivery in patients with respiratory tract.
Scientific research proves, aerobe, in pure oxygen in high pressure environment, oxygen intoxication can occur after a period of time, and too, oxygen intoxication type pneumonia appears to the mankind in the lighter; Time serious, because carbon dioxide can excite nerve, maincenter makes people initiatively breathe, if inhale pure oxygen, can benumb nerve centre; Finally because respiratory failure is dead.Human body is respectively organized and all can not be born too much oxygen, this is because oxygen itself by enzyme catalysis just can with unsaturated fatty acids acid reaction, and the phospholipid of these acid of storage can be destroyed, and phospholipid is the main component of formation cell biological film thus finally causes cell death, this process is called lipid peroxidation.In addition, to the destruction of cell, oxygen is also that it can produce free radical, bring out cancer.
Current all kinds of inhalation devices are all by the high pressure oxygen in gas storage cylinder by an air relief valve, then with a float-valve type effusion meter, regulate and measure oxygen flow; Medical pure oxygen after the process of humidification fluid humidifying, must could supply patient and use; The moisture of about 280ml because adult respiratory is approximately volatilized every day; Human body is in nature respiratory, and the high humidity of air is about about 20-80%; And moisture-free in the oxygen that oxygen generating plant produces in oxygen preparation, if do not increase humidity (not carrying out humidifying process) in use, pure oxygen can cause moisture evaporate and cause body tissue to dewater in the lung of people.
The humidifying degree of oxygen intake three degree can be divided into: humidifying is bad, humidifying is good, humidifying is excessive in clinical; Determination methods is: the bad sputum aspirator tube that causes of humidifying inserts difficulty, and expectorant is sticky, amount is few, not easily sucking-off, and pulmonary's respiratory murmur is thick or have sound of feeling sick; Humidifying is well inserted smoothly for sputum aspirator tube, and sputum is thin, measures moderate, easy sucking-off, and pulmonary's respiratory murmur is clear; Humidifying is excessively inserted smoothly for sputum aspirator tube, sputum show bubble or water sample, and amount is many, inhale not to the utmost, there is a large amount of wet sound of vomiting sound in pulmonary; Even pulmonary edema can be brought out.
At present, all kinds of oxygen absorption humidification bottles of clinical middle use are all flasks, have outlet and entrance; Oxygen to be imported by pipeline in humidification fluid (normal saline or aqueous alcohol or low concentration sodium bicarbonate solution) through entrance by purity oxygen, makes oxygen surface moisturizing, increases its humidity; Oxygen after humidifying is exported by humidification bottle and enters human respiratory tract through Oxygen tube.
The humidification oxygen bottle device that current home and abroad is seen, be all in slaking process, adopt each class methods, improve humidifying degree, and alleviate or eliminate the gur gling of slaking process generation (oxygen enters in humidification fluid, during water outlet, the sound that bubble explosion produces) because, in ward, this sound the dead of night, can affect patient have a rest or other people fall asleep.
As for the adjustment of the mixing ratio (oxygen concentration) to oxygen and air, in current oxygen suction humidifying bottle and in document, there is not been reported.Because different diseases and patient, when carrying out oxygen therapy, the oxygen concentration of suction is different.Too high oxygen concentration, often damages.Generally, concentration of oxygen inhalation is relevant with oxygen uptake flow, and computational methods are: concentration of oxygen inhalation=21%+ oxygen uptake flow * 2; Common concentration of oxygen inhalation: [low discharge 1-2L/min, middle flow 2-4L/min, high flow 4-6L/min].Special circumstances look state of an illness needs.
As for the humidifying degree regulatory function to mist, all kinds of humidification bottles in clinical at present, also do not possess.Human body is in respiratory, and when Various Seasonal, varying environment, different geographical, different temperatures, the gas humidity of needs is different.In other words carrying out in process of oxygen therapy, different seasons, different ambient temperatures, the area that mist (or oxygen) contacts with humidification fluid is how many, and its humidifying degree is different.Medically air humidity and breathe between relation closely.Under certain humidity, oxygen ratio is easier to enter blood by alveolar.Common people feel the most comfortable under the relative humidity of 45-55%.Overheated and relative humidity in unaired room is general lower, this may be bad and have stimulation to mucosa to skin.The too high perspiration functions affecting people's regulate body temperature of humidity, people can feel sultry.When due to illness carrying out oxygen therapy in medical science, the oxygen of suction is the non-natural gas that commercial run manufactures, and wherein not containing any moisture, process of oxygen therapy then must carry out humidifying process, could use.If in use (do not carry out humidifying process) to increase humidity, pure oxygen can cause moisture evaporate and cause body dehydration in the lung of people.
