Background

The aerosol inhalation therapy mainly refers to aerosol inhalation therapy, and the aerosol refers to tiny solid or liquid particles suspended in air, so that the aerosol inhalation therapy is characterized in that an atomization device is used for dispersing medicine into tiny fog drops or particles, the tiny fog drops or particles are suspended in air and enter a breathing passage and lungs, and the purposes of cleaning the air passage, humidifying the air passage, performing local treatment and performing whole-body treatment are achieved.

The aerosol inhalation therapy is a treatment method which utilizes the gas jet principle to suspend tiny droplets impacted by water drops in the air to form aerosol to be input into a respiratory tract for humidifying the respiratory tract or inhaling medicaments, the temperature of the normal nasal vestibule of a human body is 33-35 ℃, and if the temperature of inhaled gas is lower than the temperature of a body core, the gas can absorb moisture from the mucous membrane of the respiratory tract to increase the load of the respiratory tract. If the temperature of the inhaled air is higher than the core temperature of the body, the air passage can obtain energy which can be consumed as the air flows through the system structure. When the aerosol is inhaled at normal temperature, the temperature of the aerosol is lower than that of an air passage and lower than 30 ℃, the ciliary activity of the respiratory tract can be inhibited, and the respiratory tract can be stimulated more easily. During the atomization process, patients often feel uncomfortable feeling such as dryness, coldness and the like of the nasopharynx, so that many patients refuse oxygen therapy to influence the atomization effect. Especially in winter, because the liquid oxygen in the central oxygen supply equipment is converted into gas, the temperature is low, and the cold stimulation of the atomized liquid shrinks the micro-vessels in the mucous membrane of the air passage, severe cases can cause the spasm of the trachea and the bronchus, the caliber of the air passage is reduced, the inhalation quantity of the liquid medicine is reduced, aerosol particles which originally can reach the deep part of the air passage are blocked and settled on the shallow part of the air passage, and the atomization inhalation effect is reduced, even the curative effect is lost. How to reduce the discomfort caused by atomization to patients and improve the atomization effect becomes one of the problems to be solved urgently in clinical care.

In view of the above problems, there is a need to develop a heating device for an aerosol to improve the aerosol and the therapeutic effect of the aerosol.
