In the field of modern medical care and emergency treatment, a portable oxygen concentrator with battery has become an indispensable device. It can efficiently extract oxygen from the air and provide patients with the necessary oxygen therapy support.
The core working principle of a portable oxygen concentrator with battery is based on molecular sieve pressure swing adsorption (PSA) technology. This technology uses specific molecular sieve materials to separate oxygen and nitrogen in the air by pressure swing adsorption. Molecular sieve is an adsorbent with a special pore structure, and its pore size can selectively adsorb nitrogen molecules while allowing oxygen molecules to pass through.
In a portable oxygen concentrator with battery, air is first sucked into the device and compressed by a compressor. The compressed air enters the molecular sieve adsorption tower, where nitrogen molecules are adsorbed by the molecular sieve, while oxygen molecules pass smoothly and are collected. As the adsorption process proceeds, the molecular sieve will gradually become saturated, and it needs to be regenerated. The regeneration process is to reduce the pressure in the adsorption tower, so that the nitrogen molecules adsorbed on the molecular sieve are desorbed and discharged from the device, thereby restoring the adsorption capacity of the molecular sieve.
In order to achieve continuous oxygen supply, portable oxygen concentrator with battery is usually equipped with two or more molecular sieve adsorption towers. These adsorption towers alternately perform adsorption and regeneration operations to ensure that the device can continuously provide high-concentration oxygen. At the same time, the intelligent control system inside the device will automatically adjust the flow and concentration of oxygen according to the needs of the patient to meet the oxygen therapy needs of different patients.
In addition, the portable oxygen concentrator with battery also uses efficient battery technology to ensure that the device can continue to work for several hours without an external power supply. This allows patients to still receive the necessary oxygen therapy support outdoors or in emergency situations.
In summary, the portable oxygen concentrator with battery uses molecular sieve pressure swing adsorption technology to efficiently extract oxygen from the air. Its internal intelligent control system and efficient battery technology further improve the reliability and portability of the device.
