Classification of oxygen inhalers

Classification of oxygen inhalers:

1. Classified according to usage scenarios
1) Oxygen inhaler for oxygen cylinder

This inhaler is connected to a high-pressure oxygen cylinder, and it needs a pressure relief valve to change the high-pressure oxygen into low-pressure oxygen, which is then used by the patient. It is usually used in township hospitals, scientific research institutions, industrial and mining sites, >field hospitals and other environments, and its mobility is poor. The characteristics of this environment are that the place of use is relatively fixed, and the demand for oxygen is relatively large, so it will be equipped with large medical oxygen cylinders with large volume, capacity, and weight, which are inconvenient to move.

2) Wall-mounted oxygen inhaler
The inhaler connects to a wall-mounted low-pressure oxygen delivery port, so no pressure relief valve is required. It is only suitable for formal hospital wards with modern decoration design and emergency room and other environments, and it is not mobile.

3) Portable Easy Inhaler
The structure of this kind of equipment is relatively simple. Usually, it is not mandatory to be equipped with a buoy flowmeter that must be used vertically and stably. Instead, a mechanical valve is used to control the flow, and the oxygen tank that matches it is usually small in size and easy to carry. This kind of equipment is usually used in temporary use environments such as field first aid, mountaineering, and home care.

2. Classified according to the method of flow control
1) Buoy type oxygen inhaler
The buoy type oxygen inhaler is divided into two types: the oxygen inhaler for the oxygen cylinder and the wall type oxygen inhaler. The main difference is that the wall type oxygen inhaler does not need a pressure reducing valve for decompression. Its working principle is to adjust the flow of oxygen through the flow control valve, and the flow rate is displayed by the float in the flow meter. This is the most commonly used oxygen inhaler in hospitals, with mature technology and reliable quality.

2) Rotary oxygen inhaler
The turntable oxygen inhaler is adjusted by the knob of the flow control valve, and the flow rate is directly displayed through the display. Its structure is relatively simple, but when the pressure in the oxygen cylinder changes greatly, it is easy to affect the accuracy of the indication.
