Abstract

The invention discloses a medical atomizer relating to the technical field of medical apparatus and instruments and aiming at solving the problems that the existing medical atomizer is serious in drug waste, inconvenient to use, low in drug atomization efficiency and speed and long in atomization time and has the risk that pollutants such as pathogens in the air are inhaled into the airway when a patient inhales. The atomizer comprises an atomizing cup, an atomizing cup core and an atomizing cover, wherein a suction nozzle is formed in the upper part of one side of the atomizing cup; a switch is arranged at the junction of the suction nozzle and the atomizing cup; the opening or closing of the suction nozzle and the size of an opening are controlled through the switch; a pressure release hole is formed in the upper part of the other side of the atomizing cup; a filter membrane is arranged on the pressure release hole; the atomizing cup core comprises a supporting part and a nozzle casing; a narrow groove is formed in the inner wall of the nozzle casing; the narrow groove forms a gas channel; a bottom gap is formed in the bottom of the nozzle casing; and one end of the narrow groove extends to the bottom gap, and the other end of the narrow groove is communicated with the space defined by the nozzle and the nozzle casing. The medical atomizer is suitable for treating respiratory diseases.

Description

technical field [0001] The invention relates to the technical field of medical instruments. Background technique [0002] Nebulization inhalation is an important and effective way to treat respiratory diseases. It is a method of precision medicine to treat diseases. The nebulizer inhaler is used to inhale the medicinal liquid into the respiratory tract and lungs to achieve non-invasive and local treatment. , Painless, rapid and effective treatment, but also to avoid systemic complications to the greatest extent. [0003] At present, there are two main principles of nebulizers used clinically, one is an ultrasonic nebulizer, and the other is a jet nebulizer. The jet nebulizer uses compressed air to form a nebulizer through a small nozzle according to the principle of Venturi injection. The negative pressure generated by the high-speed airflow drives the liquid to be sprayed onto the obstacle together, and splashes around under the high-speed impact, so that the liquid drople...
