Abstract

The application belongs to the field of medical apparatuses, and particularly relates to a medical care atomizer with improved inner air currents. According to the medical care atomizer disclosed by the application, through a stopping member adopting an inversed truncated cone body structure, a special cavity structure and an outside air entering passage are arranged, so that fog granules with lowparticle diameter can be effectively screened and enter human bodies, and the atomization efficiency can also be improved.

Description

technical field [0001] The invention relates to a medical nebulizer, in particular to a jet nebulizer. Background technique [0002] Inhalation nebulizers deliver a therapeutically effective amount of a drug by dispersing an aqueous solution or suspension of the drug into a drug-containing aerosol of an easily inhalable size suspended in a gas, which is inhaled by the patient and deposited in the respiratory tract and / or lungs. Drugs are currently widely used to treat a variety of respiratory diseases, especially children and elderly patients with asthma or COPD, and those who are not suitable for other inhaled preparations. [0003] There are many types of inhalation nebulizers, including jet nebulizers, ultrasonic nebulizers, and vibrating mesh nebulizers. In addition, some new nebulizers are also under research or in clinical trials. Among them, the jet atomizer uses compressed gas to atomize the drug solution or suspension to achieve an atomization effect with a spray d...
