Medical atomizer

Abstract

The invention provides a medical atomizer which comprises a liquid medicine cavity, wherein an air inlet is formed in the lower portion of the liquid medicine cavity, a mist outlet is formed in the lateral surface, and a liquid adding port is formed in the upper portion of the liquid medicine cavity. A guide portion is arranged at the bottom of the liquid medicine cavity, a narrow air flow channel is formed in the guide portion, and the air inlet is communicated with the inside of the liquid medicine cavity through the narrow air flow channel. A right helicoid capillary channel is formed in the guide portion and around the position near the narrow air flow channel, the head and the tail of the capillary channel are communicated with a liquid storage region at the bottom of the liquid medicine cavity and the upper portion of the narrow air flow channel respectively, and the head of the capillary channel penetrates through the guide portion laterally. A baffle is arranged in the direction of an outlet in the upper end of the capillary channel, and a sputtering part is arranged on the baffle and sputters high-speed water flow sprayed out of the narrow air flow channel into mist which is guided to the mist outlet through the baffle. By means of the medical atomizer, atomization is performed while liquid medicines in the liquid medicine cavity are mixed continuously, therefore, the sprayed mist has uniform harmacodynamic effect, and treatment effect is improved.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular, to a medical atomizer. Background technique [0002] Nebulizer is a commonly used medical equipment, mainly used to treat respiratory diseases; its main function is to atomize liquid medicine into water mist, so that patients can directly inhale the medicine into the respiratory tract, which directly acts on the surface of the respiratory tract. Therefore, atomization Medication usually has a good therapeutic effect. [0003] At present, there are two main types of atomizers, one is a compressed air atomizer, and the other is an ultrasonic atomizer; for a compressed air atomizer, the main principle is that the gas with a larger pressure is transferred through an air pump Into the nebulizer, the gas passes through the narrow drainage channel in the nebulizer to form a high-speed airflow. The high-speed airflow, through the siphon effect, draws the liquid medicine in the nebulizer into the...

AI Technical Summary

Problems solved by technology

[0004] For the compressed air atomizer, due to its simple structure and low cost, it has been widely used; however, the problem is that when the liquid medicine is poured into the liquid medicine chamber, the atomization operation usually needs to be carried out immediately. , otherwise it is easy to tip over and spill out. Therefore, the liquid medicine in the liquid medicine cavity is often mixed unevenly, resulting in uneven drug effect of atomization, which is not conducive to providing superior atomization treatment effect
