Description

Atomizing device suitable for multiple scene

Technical Field

The utility model relates to the field of medical equipment, in particular to an atomization device suitable for various scenes.

Background

The atomization treatment is abbreviated as atomization inhalation treatment, namely, a liquid medicine is atomized into tiny fog drops (which can enter lung particles) by an atomization device, and the medicine enters the respiratory tract to reach the lung by a breathing mode, so that the purpose of local treatment is realized. Because nebulization can directly deliver drugs to the site of action in the human body, nebulization has the major advantages of faster onset of action, smaller drug dosage, and reduced systemic adverse effects compared to systemic administration of drugs, such as oral drugs, intravenous infusion. Nebulization therapy is therefore increasingly used in hospitals and households.

Currently, the scenario of nebulization therapy includes both spontaneous breathing and mechanical ventilation. The utility model patent application with publication number of CN113368348A discloses a handheld medical infant atomizer and an atomization mask, when the atomizer is used, liquid medicine in a liquid medicine cup enters an atomization block and is sprayed through the atomization block and an atomization head structure, and finally the patient is supplied with mist through the atomization mask. In the mechanical ventilation scenario, the patient needs to connect the atomizer into the respiratory pipeline for atomization treatment, for example, the patent with publication number CN215386671U is an utility model patent of a respiratory machine pipeline for atomization treatment, the patent with publication number CN112138259a is an utility model patent application of a heating and humidifying device for a respiratory machine, and the patent is connected with the atomizer and the respiratory mask through freely bendable pipelines to supply air to the patient, so that the patient is not influenced by the posture and the position of the patient during ventilation. However, in the mechanical ventilation scenario, the nebulizer can only be connected to the horizontal section of the respiratory pipeline, that is, the nebulizer should keep the state that its axis is perpendicular to the horizon line when in use, otherwise, when the tilt angle of the nebulizer is too large or connected to the vertical section of the respiratory pipeline, the nebulization effect of the liquid medicine can be reduced or even cannot be nebulized.

How to solve the problems is a technical problem to be solved.
