AI Technical Summary

Technical Problem

Traditional micro-mesh nebulizers rely on gravity for liquid supply, which makes them unsuitable for multi-angle use. Vibration of the atomizing plate causes cavitation backflow, and the lack of active delivery leads to condensation loss of the drug mist. In addition, manual cleaning of cumbersome and easily damaged parts is required.

Method used

Employing a multi-position adaptive medical nebulizer, a positive pressure is applied by a pressure piston to ensure a stable supply of medication. Combined with a media supply component, an accelerated airflow is formed, and the rotating spray disc achieves automatic cleaning, avoiding cavitation backflow and medication mist condensation, thus simplifying the cleaning process.

Benefits of technology

It achieves stable nebulization output in any posture, reduces drug mist residence time, automatically cleans the nebulizer, simplifies user maintenance operations, and improves drug utilization and ease of use.

Abstract

The present application relates to the technical field of medical apparatus and discloses a multi-position adaptive medical atomizer, which comprises an atomizer shell, a medicine storage cavity, an atomizing sheet and an atomizing outlet. The lower end of the medicine storage cavity is a cylindrical straight wall section, and the upper end is a conical flared section. An axial medicine pressing piston adapted to the cylindrical straight wall section is movably arranged in the medicine storage cavity. A liquid spraying disc corresponding to the atomizing outlet is rotatably arranged at the bottom of the medicine storage cavity. A medium supply assembly is arranged on the atomizer shell. The medicine pressing piston actively applies positive pressure to the medicine liquid when descending, so that the atomizing sheet can be stably infiltrated in any inclined posture. The atomizer eliminates the liquid supply interruption and the atomizing sheet cavitation back-suction effect caused by gravity dependence, realizes consistent atomizing output throughout the process, and accelerates the air to be directed to the atomizing outlet through the blowing port in cooperation with the medium supply assembly, thereby shortening the medicine mist retention time, reducing the condensation loss, and disturbing the airflow by the convex feature of the spraying head, thereby enhancing the medicine mist diffusion and lung penetration.
