Oxygenator

Flow sensor used in oxygenator

The oxygenator uses molecular sieve physical adsorption and desorption technology to adsorb nitrogen in the air and obtain high-purity oxygen after purification. The current oxygen therapy and oxygen health care equipment is roughly divided into health care oxygen machines with an oxygen concentration of 30%-60%, molecular sieve medical oxygen generators with an oxygen concentration of more than 90%, oxygen cylinder with higher oxygen concentration,and portable oxygen cylinders.

These devices basically rely on oxygen masks or nasal oxygen tubes to inhale oxygen, which belong to open oxygen inhalation, that is, when a person inhales a breath, in addition to the supplied oxygen, some air (21% oxygen concentration) is also inhaled, and the oxygen concentration that actually reaches the lungs is the oxygen concentration after mixing the air. In oxygen therapy and oxygen rehabilitation, too little oxygen inhalation will not achieve convalescent effect, and excessive oxygen inhalation will cause harm, so it is very important to control the oxygen flow.Gas flow sensors used in oxygen generator must be able to accurately measure ultra-low flow so that they can be used to detect when the patient is exhaling, when the air flow should be reduced, allowing the patient to exhale easily and comfortably.

▲F1031V-2 micro-flow sensor

The F1031V-2 flow sensor uses a new generation of MEMS sensor chip technology to detect the flow of the gas medium in the flow channel using the principle of thermodynamics, with good accuracy and repeatability.There is a built-in temperature sensor, each of which has a proprietary temperature compensation calibration function, and has a linear analog voltage output, which is convenient to use.

When the flow sensor is applied to the oxygen generator, it is mainly used to measure the flow of oxygen entering the system to ensure sufficient air supply. The gas flow sensor used in the oxygen generator must be able to measure ultra-low flow. By judging the breathing rhythm of the patient during sleep, according to the breathing speed, control the intake pump, and adjust the size and speed of the ventilation volume to keep the patient's breathing and intake frequency consistent, to provide sufficient oxygen concentration in the lungs.

There are many applications of flow sensors in the medical field. From hospital bed oxygen supply, floor pipeline oxygen supply to oxygen generators, ventilators, anesthetics and other medical equipment, the support of flow sensors is necessary. In addition, flow sensors play an important role in industrial production, scientific experiments, product quality control, production efficiency improvement, and energy conservation.
