Description
Technical Field
The invention relates to the technical field of medical atomizers, in particular to a novel medical atomizer.
Background
The atomization inhalation method is characterized in that high-speed oxygen airflow is utilized to enable liquid medicine to form mist, atomized liquid medicine directly enters the pharynx, the bronchus and the lung through the mouth and the nose, and the medicine directly acts on a diseased region to quickly exert the medicine effect, so that the treatment purpose is achieved; among them, the aerosol inhalation method is widely used for treating respiratory diseases to eliminate inflammation and edema, to thin sputum and to help to eliminate phlegm. Compared with the traditional means for treating respiratory diseases by taking medicines, the aerosol inhalation method ensures that the medicines directly and quickly enter the respiratory tract and the lung for deposition in a respiratory inhalation mode, thereby achieving painless, quick and effective treatment.
In the process of treating patients by medical staff through an aerosol inhalation method, a device mainly used is a medical atomizer; the medical atomizer atomizes the liquid medicine into mist by mainly using the jet atomizer, and the liquid medicine atomized by the jet atomizer is conveyed to the atomizing oxygen inhalation mask through the hose so as to be atomized and inhaled by a patient.
It should be noted that, for the existing medical atomizer, when carrying out aerosol inhalation therapy on a patient, the patient, family members of the patient or medical staff need to keep holding the jet atomizer all the time so as to keep the jet atomizer in a correct position state; in the actual operation process, because the patient position is not fixed and often can alternate the position, this jet atomizer position beat will appear and can not keep in the correct position state, and in case the jet atomizer is not in the correct position state, then can lead to the liquid medicine in the jet atomizer to incline towards one side and make the liquid medicine fully not atomize completely, and liquid medicine atomizing utilization ratio is awaited for urgent need to improve. In addition, since the liquid medicine is metered during the aerosol inhalation therapy, if the liquid medicine is not completely atomized, the quantitative aerosol therapy of the liquid medicine cannot be performed, which also affects the effect of the aerosol inhalation therapy.
In addition, for the existing medical atomizer, when the atomization inhalation therapy is carried out on the patient, the oxygen tank or the oxygen generator continuously supplies high-speed oxygen airflow to the jet atomizer, and the atomization inhalation action can be stopped only under the condition of closing the oxygen supply of the oxygen tank or the oxygen generator; when the patient does not need to inhale the atomized liquid medicine, the atomization action can not be stopped rapidly in time, so the waste of the atomized liquid medicine can be caused, and the utilization rate of the atomized liquid medicine is not high.
