It is relatively single in structure and function.
Inhalation anesthesia is achieved by inhalation of an anesthetic agent through the respiratory system. The following three factors in inhalation anesthesia operation cause the emergency reaction of the body in operation, and can induce cough and asthma of patients. 1. Airway constriction, resulting in bronchospasm, which may be caused by bronchosmooth muscle constriction by narcotics, resulting in bronchoconstriction, sudden cough or asthma, and severe cases resulting in exacerbation of the primary disease. 2. The anesthetic can inhibit central and peripheral nerves, and if the drug administration speed is too high, the body cannot tolerate the drug to possibly cause cough reflex, and sudden choking cough occurs in anesthesia. In addition, some people may be allergic to narcotic drugs to cause allergic reactions, and patients may suffer from discomfort such as laryngeal oedema, dyspnea, choking, etc. Some narcotics have direct stimulation of the airways, causing airway irritation, resulting in inflammation and swelling of the patient's airways, dyspnea, cough and wheezing, and even hypoxia. Such as isoflurane, may cause cough or asthma. 3. If there are respiratory diseases, such as allergic asthma and pneumonia, the stress reaction of the organism may be caused by anesthesia and surgery. For the above reasons, the life of the operative patient is directly threatened. Although the level of anesthesia has increased significantly over the last decade, there has been no significant reduction in the incidence of respiratory inflammation in patients due to intraoperative bronchospasm and narcotic drug stimulation. Therefore, prevention and treatment of peri-operative bronchospasm and narcotic drug irritation leading to the occurrence of airway inflammation in patients is of great significance to physicians. For problems encountered during inhalation anesthesia, it is critical that the healthcare worker respond quickly to ensure the life safety of the patient.

Correctly connect the atomizer to the anesthesia machine or the breathing machine, adjust the airflow speed and the concentration of the atomizer, etc. The effect is unstable, and the delivery effect of the atomized medicine of the atomizer is influenced by various factors, including the air flow speed and concentration set by the atomizer, the condition of a breathing channel, the breathing mode of a patient and the like. Variations in these factors may lead to fluctuations in the concentration of aerosolized drug inhaled, thereby affecting the stability of the aerosolization effect.
In the present invention, in the Mapleson a system, dead space gas is exhaled first when the patient begins to exhale. Because the dead space gas is not gas exchanged, its gas composition is the same as that inhaled by the patient. These gases enter the threaded tube while the mixed flow of atomized liquid medicine and air produced by the atomizer fills the remaining threaded tube and air reservoir. When the pressure in the circuit increases, the patient continues to exhale, and the gas exchanged alveolar gas is expelled through the APL valve.

The complexity of existing medical devices for achieving positive airway pressure is related to the choice and placement of the device. Positive airway pressure devices appropriate to the patient's condition and needs are selected and properly set and adjusted. Different devices have different functions and parameters and medical personnel need to be familiar with the method of operation and adjustment of the device. Monitoring and adjustment positive airway pressure requires real-time monitoring and adjustment of patient ventilator parameters, such as respiratory rate, inspiratory pressure, tidal volume, etc. Medical staff needs to know the breathing condition of the patient and make corresponding adjustment in time, so that the patient is prevented from being hurt by excessive ventilation or insufficient ventilation.
The invention is placed in MaplesonA system, the required atomization gas quantity per minute is calculated according to the calculation, and the required atomization gas quantity per minute is 1-2ml/kg according to the regulation of body weight. For example, a patient weighing 70kg will require an amount of nebulized gas of 70-140ml/min per minute. The atomizer generates a mixed gas of atomized medicine and air, which enters the air storage bag 3 through the atomizing passage 5 and the spiral passage 10. Under the Mapleson A system, the device consists of an air storage bag and an APL valve close to the patient end, when the device exhales, the gas exhaled by the patient enters the air storage bag 3, when the device exhales, the air storage bag 3 contracts and supplies fresh atomized gas and air to the patient, and the APL valve is positioned between the air storage bag 3 and the patient end, and the resistance is regulated according to the requirement to control the flow of the gas and the end-expiratory pressure. When exhaling, the APL valve opens, allowing a portion of the exhaled air to pass through, but at the same time allowing a mixture of nebulized gas and air to enter the reservoir bag 3. In this way the patient is provided with sufficient atomising gas during exhalation, thereby minimising the risk of repeated inhalation. The invention simplifies the complexity of positive pressure ventilation in medical treatment. On one hand, positive pressure ventilation is realized by combining an atomizing machine with the cooperation of an atomizing channel and a spiral channel, the inspiration pressure and the tidal volume are ensured, the breathing frequency can be observed through the fluctuation change of the air storage bag, and on the other hand, the invention is arranged in a Mapleson A system, so that the effective ventilation quantity of atomized gas can be ensured, and the treatment effect is realized under the condition of ensuring the normal breathing quantity.
