Background

Portable oxygenerators are of two types, one of which is chemical formulation water-added oxygen production, and the disadvantage is that they cannot last, only for more than 10 minutes at a time, and are not controllable. Another molecular sieve pulsed, such as the Qingdao smart portable oxygenerator, is molecular sieve, which can be supplied with oxygen from a battery for up to 4 hours, which is a pulsed oxygen supply mode, supplying oxygen based on inhalation. The weight of the vehicle-mounted hydraulic lifting device is only 2 kg, and the vehicle-mounted hydraulic lifting device can be used on a vehicle and a plateau. So the portable oxygenerator is different from the common oxygenerator in that: can be powered by a battery, and has small volume and light weight. The common oxygenerator is generally above 8 kg, and the portable oxygenerator, such as Qingdao, is only 2 kg (containing a battery) for pulse oxygen supply, the common oxygenerator is continuously supplied with oxygen when people exhale, but the oxygen can not be inhaled into the lung, and the oxygen utilization rate is low. The portable pulse oxygen supply mode for preparing oxygen only supplies oxygen during inspiration, and does not supply oxygen during expiration, so that the oxygen utilization rate is extremely high. The portable oxygenerator can be powered on a vehicle, and the battery is used for supplying power, so that the portable oxygenerator is more suitable for carrying with oxygen for inhaling compared with the common oxygenerator which can only supply power for 220V.

At present, the pull rod structure of the portable oxygenerator is still of a traditional structure, the pull rod structure is of a straight rod type structure, and the angle adjustment and push-pull state switching cannot be carried out according to actual demands, so that the best stress adjustment requirement is difficult to achieve, and the requirements of battlefield, accident scene, field travel health care and various different-level crowds are difficult to meet.
