Adapt to the characteristics of the African market
Air source type adaptation
High pressure oxygen cylinder: It is still mainstream in areas with poor infrastructure, and a regulator with an inlet of 150-300 bar needs to be selected.
Oxygen concentrator/concentrator: In cities and hospitals with relatively stable electricity, it can be equipped with a regulator with an inlet pressure of 0.4-1.5 MPa.
Centralized oxygen supply pipeline: In large hospitals, it is necessary to select a manifold/pipeline pressure regulator (applicable to ISO 10524-2).
Adaptation to environment and usage habits
High temperature, high humidity, and dusty environment: The selection should consider sealing, dust prevention, and corrosion resistance.
Frequent handling and transportation: Prioritize selecting regulators with sturdy structures and impact resistance.
Operator training level: Try to choose products with clear flow meters, pressure gauges, and anti misoperation structures.
Maintenance and spare parts
In some parts of Africa, the supply cycle of spare parts is long. It is recommended to choose models with universal interfaces, easy disassembly and maintenance;
Used in medical settings such as hospitals, clinics, emergency vehicles, and home oxygen therapy, the oxygen purity requirement is high (usually ≥ 99.5%) and must comply with relevant medical gas standards.
Common specifications include 2L, 4L, 8L, 10L, 12L, 15L, 40L, etc. Among them, 4L, 10L, 15L, and 40L are the most common in medical settings.
Gas cylinders classified by gas capacity
The global medical oxygen cylinder market is usually divided into the following categories based on capacity, and the African market also follows this classification system:
Below 5L
Mainly used in home care, short-term oxygen therapy, emergency transportation and other scenarios, it has good portability, but the single use time is relatively short.
Common specifications include 2L, 4L, etc.
5–10L
Suitable for hospital wards, clinics, and outpatient nursing institutions, it can meet the needs of moderate flow and long-term oxygen therapy.
Common specifications include 10L, etc.
11–15L
It is commonly used in intensive care settings such as ICU, emergency room, and operating room, supporting high flow rates and prolonged oxygen supply.
Common specifications include 15L.
16–20L
Mainly used in hospitals and long-term care institutions to provide high-capacity, long-term oxygen therapy for patients with severe respiratory distress or chronic diseases.
Common specifications include 20L, etc.
Above 20L
Suitable for special applications such as hyperbaric oxygen therapy, anesthesia, and centralized oxygen supply systems in large hospitals, with large capacity and long oxygen supply time.
Common specifications include 40L, etc.
Classification by gas source form
1. Compressed gaseous oxygen cylinder
Compressing and storing high-pressure oxygen in gas cylinders, which is convenient to use and plug and play, is the most common way of oxygen supply in medical settings.
Suitable for various emergency, temporary use, and home oxygen therapy scenarios.
2. Liquid oxygen system
Storing oxygen in liquid form has a large capacity and long service life, suitable for patients who require long-term continuous oxygen supply or centralized oxygen supply systems in large hospitals.
But the system is complex and costly, and is often used in scenarios such as intensive care and hyperbaric oxygen therapy.
3. Oxygen concentrator+oxygen cylinder combination system
Oxygen concentrators separate oxygen from the air through pressure swing adsorption or membrane technology, and use small capacity oxygen cylinders as backup or mobile oxygen supply.
Suitable for long-term home oxygen therapy, medical oxygen supply in remote areas or areas with unstable electricity.
