The development of adsorption-based air separation technologies has led to the emergence of medical oxygen concentrators, significantly enhancing the speed and quality of healthcare delivery. Today, oxygen concentrators are considered essential medical equipment worldwide.
In this article, we examine in detail the working principles, efficiency, and specifications of our proprietary Oxymedic series medical oxygen concentrators, which entered mass production in 2023.
Working Principle
Our ten years of experience in gas generation technology and our expertise in oxygen production through pressure swing adsorption (PSA) allowed us to develop our own reliable and efficient equipment.
Oxygen concentrators operate based on adsorption air separation. The separation unit consists of two columns filled with adsorbent. Compressed, dried air enters the columns, where oxygen is separated and directed to the user, while other gases are trapped by the adsorbent. The adsorbent is then regenerated by depressurisation or heating. The primary function of the adsorbent is to capture nitrogen molecules from ambient air.
These systems are capable of producing oxygen with concentrations up to 95 %. For medical purposes, a concentration of 90 % or higher is sufficient, as defined in GOST 31056-2002 (ISO 8359:2008) “Oxygen Concentrators for Medical Use.” Oxygen concentration and flow are regulated through the concentrator’s control panel. Higher purity levels can be achieved using additional equipment, although this is not necessary for medical use.
Applications
The most common medical conditions requiring oxygen therapy include:
- Pulmonary hypertension
- Heart failure
- Bronchial asthma
- Complications from COVID-19
- Fetal hypoxia during pregnancy
- Cystic fibrosis
- COPD
Oxygen therapy is also used during anaesthesia, for patients with weak respiratory function post-surgery, and to accelerate recovery after illness or intense physical activity.
Technical Specifications
When choosing a medical oxygen concentrator, key specifications to consider include performance capacity, dimensions, and noise levels.
Our product line includes various models with output capacities ranging from 10 to 1,500 litres per minute. The appropriate model should be selected according to the specific requirements of the medical facility and in compliance with Russian healthcare construction regulations, particularly the provisions of Russian construction code Svod Pravil (SP) 158.13330.2014 (Buildings and Premises for Medical Organisations), developed by the GIPROZDRAV Research and Design Institute — Russia’s national body for medical infrastructure planning.
We recommend consulting with our specialists to ensure the optimal configuration of the equipment.
