Medical respirator achieving aerosolization

Abstract

The invention discloses a medical respirator achieving aerosolization. The respirator comprises a respirator main body, an inner cavity of the respirator main body is internally provided with an oxygen supply device and an aerosolization box, the oxygen supply device comprises an air-oxygen mixer, and the air-oxygen mixer is communicated with an air pipeline, a pure oxygen pipeline and a mixed gaspipeline in sequence; an inner cavity of the aerosolization box is internally provided with a liquid medicine box, medicine delivery pipes are symmetrically communicated with the liquid medicine box,a compressed air blower is arranged on the liquid medicine box, a straight duct is communicated with an air outlet, the straight duct is communicated with a trapezoidal duct which is communicated with a thin duct, the symmetrical medicine delivery pipes and the thin duct are gathered and communicated, and an atomization mesh is arranged in the thin duct. According to the medical respirator achieving aerosolization, humidified gas moderate in air-oxygen ratio can be provided, for a patient needing aerosolization, the device can meet the requirements of oxygen inhalation and aerosolization of the patient simultaneously, equipment replacement is not needed, and convenience is brought to use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical ventilator capable of nebulizing drug delivery. Background technique [0002] Medical ventilator is a device that can effectively replace, control or change people's normal physiological breathing, increase lung ventilation, improve respiratory function, reduce respiratory consumption, and save heart reserve. It occupies a very important position in modern clinical medicine, but Most of the existing ventilators have a single function and can only supply oxygen, which cannot meet the needs of patients who need nebulized drug delivery while inhaling oxygen. [0003] In the prior art, a medical ventilator with the application number "201810284949.7" includes an inhalation pipeline and an exhalation pipeline. The inhalation pipeline is sequentially provided with a humidification tank and a The first water storage cup; the second water storage cup is arranged on the...

AI Technical Summary

Problems solved by technology

[0004] However, there are still relatively obvious defects in its use: the ventilator only has the function of oxygen supply, and it lacks adaptability to patients who need nebulized drug administration while inhaling oxygen. The patient needs to stop oxygen inhalation and remove the inhalation Oxygen device can only be used for atomization, which is not only troublesome to operate, but also prolongs the treatment time, which is not good for the patient's recovery
