Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a ventilator with an adjustable positioning structure. Background Art

[0002] Patients with more serious conditions often have difficulty breathing and need external help to carry out normal respiratory metabolism. During the treatment, if they are separated from the assistance of oxygen supply equipment, they may suffer from hypoxia and suffocation. Ventilators, as an effective means of artificially replacing the spontaneous ventilation function, have been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy and emergency resuscitation, and occupy a very important position in the field of modern medicine.

[0003] In the prior art, the oxygen cylinder of the ventilator is mostly fixed by hanging on the outside of the ventilator. This fixing method makes it easy for the oxygen cylinder to collide with other objects during the movement of the ventilator.
