"Medical molecular sieve oxygen equipment general technical specifications": air as raw material, the use of molecular sieve pressure change adsorption process production of oxygen. The oxygen concentration of this oxygen is 90%~96% (V/V), and the remaining components are mainly argon and nitrogen. Generally speaking, it will be stipulated that medical oxygen must reach 93% to be considered as a standard before it can be put into use in clinical treatment.
Two, home oxygen concentrator oxygen concentration is how much
Home oxygen concentrator oxygen concentration spanning a wide range, generally in the range of 30% ~ 90% ± 3%. As with the average oxygen concentration of about 35%, it is suitable for office workers and students. It can eliminate fatigue, restore and improve sleep; generally 60% oxygen concentration is suitable for the elderly, long-term use. Elderly people can prolong their life; for patients, 90% oxygen concentration meets the standard of medical oxygen.
Three, medical oxygen concentrator oxygen concentration standard why is 93% ± 3%
According to the national food and drug administration part of the relevant provisions of the medical oxygen must reach 93% to be considered the standard, in order to put into use in the clinical treatment. That medical oxygen concentrator oxygen concentration standard why is 93% ± 3%? Mainly because the human body with the help of medical oxygen concentrator oxygen inhalation, at the same time will also inhale part of the air containing 20.98% oxygen purity, so that the real inhalation of oxygen concentration will also be diluted. According to the test, the concentration of oxygen inhaled into the throat is about 45%. According to the human body structure characteristics, inhaled oxygen to go through 32 levels of attenuation process, in fact, the real down, 93% of the oxygen concentration, the human body after inhalation of oxygen is utilized by the oxygen concentration is about 30%. Therefore, in order to ensure that patients can normally receive oxygen assisted treatment, the oxygen concentration must reach about 93%, in order to ensure that the patient's oxygen needs.
Also in 1988, the State Administration of Pharmaceutical Affairs formulated and issued the "General Technical Specification for Medical Molecular Sieve Oxygen Generating Equipment," mentioning that the oxygen concentration of medical oxygen generators should be greater than 90%, which is collectively referred to as 93% of the oxygen concentration. Medical oxygen equipment in accordance with the provisions of the second class of medical device management, by the provincial food and drug regulatory departments into the type of approval, registration. Oxygen generator are in the food and drug regulatory authorities within the scope of management, both for hospital patients auxiliary treatment and special industry oxygen needs, but also for the need for home oxygen therapy patients to provide effective medical oxygen.
