A medical nebulizer

Abstract

The invention provides a medical atomizer. The medical atomizer includes a shell body, the shell body is internally provided with an atomizing cavity and an air pump separately, an air feeding port ofthe air pump is communicated with an air inlet communicated with external atmosphere, and a high-pressure air outlet of the air pump is communicated with the lower end of a high-pressure airflow channel; the high-pressure airflow channel runs through a bottom cavity wall of the atomizing cavity and a to-be-atomized medicinal liquid stored in the lower half part of the interior of the atomizing cavity in sequence, and a high-pressure airflow nozzle is arranged at the upper end of the high-pressure airflow channel; the outer side of the high-pressure airflow channel is provided with a medicinesucking channel, an upper end opening of the medicine sucking channel is positioned at the high-pressure airflow nozzle, and a spacer is arranged above the high-pressure airflow nozzle and the upper end opening of the medicine sucking channel; a medicine fog smashing mechanism is arranged on the spacer; an atomizing outlet is formed in the upper end of the atomizing cavity and connected with an atomizing shield through a corrugated pipe. A secondary atomization smashing effect can be achieved on medicine fog particles generated by a traditional compressed-air-type atomizer, finally dischargedatomized particles are finer, and absorption of the particles in the human body is better facilitated.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a medical nebulizer. Background technique [0002] The nebulizer is mainly used to treat respiratory diseases. It is a commonly used medical device. Its main function is to atomize liquid medicine into water mist, so that patients can directly inhale the medicine into the respiratory tract and directly act on the surface of the respiratory tract. Therefore, atomization Treatment usually has a good therapeutic effect. [0003] The basic principle of the current compressed air atomizer is that the gas with relatively high pressure is pumped into the atomizer through the air pump, so that the gas is drained through the narrow airflow channel in the atomizer to form a high-speed airflow. Siphon effect, the drug liquid in the atomizer is sucked into the airflow through the drug absorption channel of the capillary structure, and is lased on the barrier (separator) together w...

Problems solved by technology

However, due to the limitation of the structure and output power of this kind of nebulizer, the fineness of the atomized particles is not high, which makes it difficult to be fully and timely absorbed by the human body after inhalation; in addition, the larger atomized particles are not easy to diffuse, and more Condensation is prone to occur, reducing the atomization efficiency
