1, according to the use of the scene classification
(1) oxygen cylinder oxygen inhaler
This kind of inhaler and the high-pressure oxygen cylinder connection, it needs a decompression valve to change the high-pressure oxygen into low-pressure oxygen, and then for the patient to use. It is usually used in environments such as township hospitals, scientific research institutions, industrial and mining sites, and field hospitals, where mobility is poor. Such environments are characterized by a relatively fixed place of use and a relatively large demand for oxygen, so they will be equipped with large medical oxygen cylinders that have a large volume, capacity and weight and are difficult to move.
(2) Wall-mounted Oxygen Inhaler
This type of inhaler is connected to a wall-mounted low-pressure oxygen delivery port and therefore does not require a pressure reducing valve. It is only suitable for environments such as wards and emergency rooms in formal hospitals with modern decorative designs and is not mobile.
(3) Portable Oxygen Inhaler
This type of equipment is relatively simple in structure, usually not mandatory to equip with a buoy flow meter that must be vertically stabilized, but rather a mechanical valve to control the flow rate, and the oxygen tanks that go with it are usually small in size and easy to carry. This equipment is usually used in the field first aid, mountaineering, home care and other temporary use of the environment.
2, according to the method of flow control classification
(1)? Buoy oxygen inhaler
Buoy oxygen inhaler is divided into oxygen inhaler for oxygen cylinder and wall oxygen inhaler, the main difference is that wall oxygen inhaler does not need pressure reducing valve to reduce pressure. The main difference is that the wall oxygen inhaler does not need a pressure reducing valve to reduce pressure. The working principle is to regulate the flow of oxygen through the flow control valve, and the flow size is displayed by the buoy in the flow meter. This is the most commonly used oxygen inhaler in hospitals, with mature technology and reliable quality.
(2)Turntable Oxygen Inhaler
The turntable oxygen inhaler is adjusted by the knob of the flow control valve, and the size of the flow rate is directly displayed by the indicator. Its structure is relatively simple, but when the pressure inside the oxygen cylinder changes greatly, it is easy to affect the accuracy of the display.
How to use the portable oxygen inhaler
1. Preparation and inspection before use
Before use, you must go to the legal medical oxygen station to fill oxygen. Check the amount of oxygen storage, open the cylinder switch, observe the oxygen pressure gauge that can be seen in the oxygen storage cylinder storage of oxygen, such as the pressure of oxygen is less than 0.05-0.1MPa, should be supplemented with medical oxygen.
2, the use of humidifier
(1) when using unscrew the upper cover, add distilled water or cold water to the humidifier to the upper and lower water level between the lines. Tighten the upper cover, the water level is lower than the lower mark in time to add water.
(2) According to the marking on the upper part of the humidifier, connect the oxygen supply pipe to the oxygen supply nozzle of the humidifier, and connect the oxygen suction pipe to the oxygen discharge nozzle of the humidifier, and do not connect the opposite.
(3) Carefully check whether the oxygen guide tube, oxygen absorbing tube, humidifier, are clean before use.
(4) When the oxygen passes through the humidifier, you can see bubbles appearing in the cup, indicating that the humidifier is working properly.
3, oxygen
Slowly open the cylinder switch, according to the need to adjust to the appropriate flow rate and then insert the oxygen nasal plug into the vestibule part of the nose can be oxygen. After the oxygen intake is completed, first pull out the nose plug and close the cylinder switch, and then close the flow regulating valve when the pressure drops to 0.
Portable Oxygen Cylinder Precautions
1, filling oxygen must go to the legal medical oxygen filling station.
2, humidifier is strictly prohibited tilt.
3, the use of environmental temperature shall not exceed 40 ℃.
4, cylinder switch, open and close should be slow, do not force too hard.
5, the oxygen supplier should be strictly prohibited from staining oil, prohibited collision, throwing and dropping, away from heat, fire and flammable and explosive substances, to avoid direct irradiation of strong sunlight, shall not be pasted with rubber paste.
6, non-use period, the cylinder switch must be closed.
7, the oxygen pressure in the cylinder shall not be less than 0.05MPa.
8, the product failure can not continue to use, and shall not be arbitrarily disassembled, and timely and dealers or manufacturers to contact.
9, according to the time of the cylinder shoulder stamp, every three years to send a legally qualified inspection unit for inspection.
10, hypoxic disease patients, should be under the guidance of a doctor to choose the size of the oxygen flow.
11, the first time to the oxygen cylinder filled with oxygen, should be medical oxygen replacement.
Oxygen inhaler calibration procedures
1, appearance check.
2, working pressure check.
3, sealing check.
4, moisturized bottle pressure strength check.
5, flow meter check.
6, safety valve exhaust pressure check.
7, oxygen pressure gauge calibration.
