Spray inhaler mouthpiece for asthma treatment

Abstract

The invention provides a spray inhaler mouthpiece for asthma treatment. The spray inhaler mouthpiece comprises a buccal nozzle and a spherical flow guide cavity, wherein the spherical flow guide cavity comprises an outer spherical wall and a flow guide wall; a return wall toward the inner side of the flow guide wall extends out of the joint of the outer spherical wall and the buccal nozzle; the flow guide wall is self-enclosed to form a main circulation channel; an airflow sandwich channel is formed between the outer spherical wall and the flow guide wall; and a convection channel is formed between the return wall and the flow guide wall. The main circulation channel, the airflow sandwich channel and the convection channel are matched to guide medicine mist, so that the medicine mist discharged from the buccal nozzle is closer to the external temperature, the stimulation of low-temperature medicine mist in temperature is reduced, the condition that the medicine mist is condensed into liquid drops is completely avoided and the mouthfeel is improved. The medicine mist discharged from the airflow sandwich channel is guided into the main circulation channel in the convection channel and meets with a small amount of medicine mist circulating in the main circulation channel to counteract partial impact force, so that the stimulation of the medicine mist in speed is reduced.

Description

technical field [0001] The invention belongs to the technical field of atomizer accessories, in particular to a mouthpiece of an atomized inhaler for treating asthma. Background technique [0002] Asthma generally has symptoms such as wheezing, shortness of breath, chest tightness and coughing, and the intensity changes with time. The treatment of asthma generally adopts the method of drug inhalation, using a nebulizer to atomize the drug, and the patient holds the mouthpiece of the atomizer inhaler to inhale the drug to achieve the purpose of treatment. [0003] The mouthpiece of the existing atomizing inhaler is generally made into a cylindrical shape that the mouth can contain. The mouthpiece is assembled on the air outlet of the atomizing inhaler, or is connected with the air outlet of the atomizing inhaler after a pipeline is arranged. The mouthpiece of the current atomizing inhaler has a single structure, and it is easy to form liquid beads when it is cold or hot, whi...

AI Technical Summary

Problems solved by technology

The mouthpiece of the current atomizing inhaler has a single structure, and it is easy to form liquid droplets when it is cold or hot, which affects the inhalation taste and is inconvenient to use, and sometimes the medicine with a lower temperature can irritate the bronchi

In order to solve the above problems, those skilled in the art add a preheating module to the nebulized inhaler to preheat the liquid medicine or the nebulized medicine, but adding the preheating module will undoubtedly increase the cost of the nebulized inhaler, and the temperature is not easy to control , although it will not irritate the bronchi due to the low temperature of the drug, it is easier to form droplets

In addition, the current nebulizer inhaler directly and quickly sprays out the cold air flow, which has a strong sense of stimulation
