Abstract

The invention relates to a high-efficiency vibration atomizer. The high-efficiency vibration atomizer comprises an atomizer body, a three-way pipe and a ventilation piece; the atomizer body comprisesa medicine storage tank, a cable joint and a connecting pipe; a vibration mesh micro-spraying structure is arranged at the joint of the cable joint and the connecting pipe; the vibration mesh micro-spraying structure comprises a first piezoelectric ceramic sheet, a second piezoelectric ceramic sheet and a microporous plate; the first piezoelectric ceramic sheet and the second piezoelectric ceramicsheet are respectively arranged at two sides of the microporous plate; and a microporous net is arranged in the center of the microporous plate. When the first piezoelectric ceramic sheet and the second piezoelectric ceramic sheet are in an electrified state, the first piezoelectric ceramic sheet and the second piezoelectric ceramic sheet drive the microporous plate to deform, and then the microporous plate vibrates. The high-efficiency vibration atomizer has the advantages that a traditional vibration mode is changed, so that a liquid medicine in a medicine storage tank can be vibrated and atomized; the liquid medicine particles are small; the administration efficiency is high; deposition of the circuit of a breathing machine is reduced; and the comfort level of patients is good.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a high-efficiency vibrating atomizer. Background technique [0002] The lung has physiological and anatomical characteristics such as huge alveolar surface area, thin alveolar cell membrane, rich capillary network, narrow air and blood pathway, low enzyme activity, and slow clearance rate in the deep lung. Compared with other routes of administration, aerosol inhalation has the advantages of small drug dosage, large absorption surface area, rapid onset of action, avoidance of hepatic first-pass effect, small systemic side effects, and convenient use. Nebulization inhalation is a direct drug delivery method with the respiratory tract and lungs as the target organs. It has the advantages of quick onset, high local drug concentration, less dosage, convenient application and less systemic adverse reactions. treatment means. The atomized inhalation device is a drug deliv...
