High-performance mesh screening-type nebulizer

Abstract

The invention provides a high-performance mesh screening-type nebulizer, and belongs to the field of medical apparatus and instruments. The high-performance mesh screening-type nebulizer comprises a medicine liquid tank (1), a medicine liquid cover (5) to seal the medicine liquid tank (1), a mask joint (2), a separating plate, a mist storage tank body (3) and a detachable pedestal connected to thelower part of the mist storage tank (3). The medicine liquid tank (1) and the mask joint (2) are arranged on the separating plate, and are detachably connected to the mist storage tank (3) through the separating plate. The medicine liquid tank (1) can make the medicine liquid formed into medicine liquid particles with the MMAD value less than 5 micron, the medicine liquid particles are deliveredinto the mist storage tank body (3) and then inhaled by the patient via the mask joint (2). The high-performance mesh screening-type nebulizer provided by the invention is a nebulizing and inhaling device suitable for nebulizing and inhaling of children and adults. The device has the characteristics of high nebulizing-inhaling rate, low working noise, low use cost, high convenience, etc.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a high-performance mesh type atomizer. Background technique [0002] At present, the domestic atomization market has great potential and maintains rapid growth every year, mainly because the atomization inhalation of drugs has the advantages of strong targeting, high bioavailability, and small side effects. [0003] At present, there are two main types of nebulizers used in medical institutions on the market, compressed gas nebulizers and ultrasonic nebulizers. The compressed gas atomizer uses the Venturi effect to atomize the liquid medicine by outputting high-pressure and high-speed airflow. The main disadvantage of this atomization method is that the atomized particles are uneven in thickness, the effective atomization inhalation rate is low, and the working noise is relatively large. Ultrasonic nebulizers use ultrasonic waves to atomize liquid medicine. In this...

AI Technical Summary

Problems solved by technology

With this atomization method, the atomized particles are thicker and the drug inhalation rate is low

On the other hand, when the patient uses the above two nebulizers for nebulization treatment, during the exhalation phase, the drug particles cannot be inhaled by the patient, which is in a state of complete waste

In addition, no matter what kind of atomization generating equipment, there is a high purchase cost, and it is difficult to carry out atomization treatment at home.
