Reason: This device is effective in providing safe oxygen for the patient to breathe.
The principle is as follows:
Dry oxygen entering the oxygen cylinder from port A is output below the water surface, where it forms bubbles and returns to the surface of the water, where it is output from port B and inhaled by the patient. In the process of rising from the water, some water vapor is taken away by the bubbles, so that the output of oxygen with a certain amount of water vapor "damping".
Medical oxygen output from the cylinder, through the decompression reducer, does not contain solid impurities and therefore does not require filtration.
In addition, the outlet of the oxygen tubing is not directly connected to the patient's nostrils, but is placed around the nostrils, creating an area of high oxygen content, so the bottle is not prevented from rushing directly into the respiratory tract.
In addition, the level of water in the bottle is necessary, not too high, so as not to oxygen directly into the patient's respiratory tract with a large number of water droplets
The reason for filling the water is to avoid the continuous dry oxygen into the trachea, so that the surface of the alveoli is dry and interfere with the exchange of gases, which is in the tracheotomy patients must be special attention to the oxygen must be used.
Expanded information:
Medical Oxygen Concentrator, a new type of equipment for extracting oxygen from the air based on Pressure Swing Adsorption (PSA) technology.
The product mainly utilizes molecular sieve physical adsorption and desorption technology to fill molecular sieve in the oxygen concentrator, which can adsorb nitrogen in the air when pressurized, and the remaining unabsorbed oxygen will be collected, and then purified and processed to become high-purity oxygen.
When in use, the compressed air is purified by the air purification dryer, and then enters the adsorption tower through the switching valve, and in the adsorption tower, nitrogen is adsorbed by the molecular sieve, and the oxygen is collected at the top of the adsorption tower and enters into the oxygen storage tank, and then filtered by the odor removing, dust removing and sterilization removing filters to obtain qualified medical oxygen
