An improved oxygen-driven atomization device

technical field

The invention relates to the field of medical instruments, in particular to an improved oxygen-driven atomization device.

Background technique

At present, the commonly used oxygen nebulizers in clinic include mouth type and mask type. In general, the oral nebulizer is the first choice, but for the elderly, those with cognitive impairment and those who cannot cooperate, the mask-type nebulizer is clinically selected. The oral nebulizer is easy to use, and the assisted ventilation treatment process of the mask ventilator can be completed only through the interface, and does not affect the patient's nasal cannula oxygen inhalation. The mask-type nebulizer is not as convenient to use as the oral-type nebulizer in design. If the patient lacks an interface when performing ventilator-assisted ventilation, the patient must first suspend the ventilator treatment. During the use of the two nebulizers, there is a risk of contamination when adding nebulized and inhaled drugs, which do not conform to the principle of aseptic operation.

A spacer block is designed on the periphery of the lower part of the cavity plate. When the oxygen mask is connected with oxygen again, the medical liquid in the atomizing cup can be atomized by the oxygen flow, and the aerosolized medical liquid can be inhaled by the patient after being mixed with high-pressure oxygen. This patent document provides a medical atomized oxygen The nebulizer can realize the atomization treatment of medicinal liquid, simplify the treatment steps and improve the treatment effect, but the medical atomization oxygen mask lacks the oxygen supply capacity for special oxygen-demanding people, which increases the treatment cost and operation process in the actual use process. And it is not conducive to the addition of aerosolized drugs in the middle.
