The oxygen inhaler in the oxygen supply system refers to a device used to provide additional oxygen supply to patients.

The oxygen supply system usually consists of the following components:

1. Oxygen source: This can be a compressed oxygen tank, liquid oxygen tank, or oxygen generator, etc.

2. Flow regulator: used to regulate oxygen flow to meet the needs of patients. It usually has a scale or numerical display so that medical staff can accurately set the required oxygen flow rate.

3. Oxygen pipeline: Transport oxygen from the oxygen source to the oxygen inhaler and respiratory interface.

4. Respiratory interface: This is the part that connects the patient to the oxygen inhaler, usually a mask, nasal cannula, or oxygen cap.

Oxygen inhaler improves respiratory function by delivering oxygen to the patient's respiratory system, increasing the oxygen content in the patient's breath. The use of oxygen inhalers requires a doctor's prescription and guidance, and should be properly set and adjusted according to the patient's needs.

Oxygen inhalers are mainly used to treat conditions of oxygen deficiency, such as chronic obstructive pulmonary disease (COPD), heart failure, bronchitis, etc. It helps patients breathe better and reduces the body's demand for oxygen by increasing the oxygen content in their breath.

The use of oxygen inhalers requires a doctor's prescription and guidance, as excessive use of oxygen may lead to oxygen poisoning. Oxygen inhalers should be regularly inspected to ensure their proper functioning, and oxygen tanks should be replaced promptly.

Oxygen inhalers in oxygen supply systems are widely used in medical institutions, emergency vehicles, home care, and other places to provide necessary oxygen support and treatment.
