Description

Circulating atomization mechanism

Technical Field

The utility model relates to the technical field of medical equipment, more specifically, the utility model relates to a circulation atomizing mechanism.

Background

Respiratory diseases belong to a common disease and a frequently encountered disease. Currently, aerosol inhalation therapy is mostly used for treating various respiratory diseases. Aerosol inhalation therapy is a very important and effective treatment for existing respiratory diseases. The atomization inhalation therapy is to atomize the liquid medicine into tiny particles by adopting an atomization inhaler to finally form medicine mist, and the medicine mist enters the respiratory tract and the lung of a human body for deposition in a breathing inhalation mode, thereby achieving the aim of painless, rapid and effective therapy.

In the existing aerosol inhalation therapy, in order to achieve the aerosol treatment of the medicine, a medical ultrasonic nebulizer and a medical compression nebulizer are generally used. The medicament or liquid atomized by ultrasonic atomization or compressed air atomization is the common anti-inflammatory medicinal mist nowadays. In fact, long-term inhalation of these anti-inflammatory mists can cause drug resistance or other side effects in humans. The research shows that the salt powder is taken as a therapeutic agent (salt therapy) for people to take, so that the side effect caused by the anti-inflammatory drug mist can be effectively avoided, and the similar or even better therapeutic effect can be achieved. The salt therapy treatment method specifically comprises the following steps: the salt particles are atomized into salt fog (the diameter of the dust is between 1 micron and 50 microns), and then the salt fog is inhaled by a patient, and can be directly adsorbed to the oral cavity, throat, trachea, bronchus, alveolus and the like of the patient and adsorbed by the mucosa of the patient, so that the effects of sterilization and inflammation diminishing are achieved for the human body, and then the salt fog can be discharged out of the body along with the breathing to achieve the purpose of treatment.

As can be known from the above discussion, when the respiratory diseases are treated by aerosol inhalation, no matter anti-inflammatory drugs or salt powder are adopted, equipment with an atomization function is essential. However, most of the existing atomization devices have complex structures, slow atomization speed and poor atomization effect, and finally the atomization inhalation treatment effect is poor.

Therefore, it is necessary to develop a new structure of the atomizing mechanism to solve the problems in the prior art.
