Description

Auxiliary device for allergic asthma treatment

Technical Field

The invention relates to the technical field of asthma treatment, in particular to an auxiliary device for treating allergic asthma.

Background

Allergic asthma is a relatively intractable disease, often occurring in infants and young children, and if neglected, it may be accompanied by life-long. Most asthma patients have allergic phenomena or allergic rhinitis, and the precursors of the asthma patients with allergic rhinitis have symptoms such as sneezing, rhinorrhea, rhinocnesmus, itchy eyes, lacrimation and the like. Since the symptoms are similar to those of respiratory tract infection or inflammation, the adult lacks relevant knowledge, often neglects treatment in the early stage, and is also very likely to be misdiagnosed.

Inhalation therapy is the best method for treating allergic asthma at present, and local inhalation is used for enabling the medicine to directly reach a main part of a lesion, namely a small airway, in a high concentration in an atomizing mode through airflow movement of the respiratory tract, and has the advantages of quick response and small dosage. The medicine has the advantages of no pain, humidifying air passages, diluting sputum and the like, particularly, the medicine is absorbed through the air passages and rarely enters blood, even if a very small amount of medicine enters blood circulation, the medicine can be quickly inactivated in the liver, the adverse reaction of the whole body is light, and the medicine can be widely used for various respiratory diseases. In recent years, the normative inhalation therapy has become the first choice for the prevention and treatment of allergic asthma, and is vigorously advocated by the world health organization.

At present, a quantitative aerosol inhaler can be used for patients over seven years old, when the aerosol inhaler is used, the patient needs to exhale air in the lung, put a nozzle in the mouth, close the lip, press a button while inhaling the air in the mouth, then the atomized medicine is sprayed into the mouth of the patient through the nozzle, then the patient needs to hold a breath for ten seconds, or hold the breath for as long as possible without uncomfortable feeling, and then exhale, and the technical requirement is high, on one hand, after the patient exhales the air in the lung, in the process of putting the nozzle in the mouth and then pressing the button, the patient already breathes in more air in the mouth, so that the inhalation of the medicine is influenced, on the other hand, after the patient inhales the medicine, the patient can exhale the medicine quickly, so that most of the medicine entering the mouth is discharged into the air, not only influences the effect of the patient who carries out the aerosol therapy, has caused the waste of treatment medicine simultaneously, for this reason, we propose an auxiliary device for allergic asthma treatment.
