Background
The prior medical anesthesia apparatus technical field, an anesthesia air storage bag is a matched device of an anesthesia machine, and the structure comprises an air bag and an air storage. The function is only used for storing and regulating the gas generated in the anesthesia machine to supply the needs of the patient for anesthesia, ventilation and breathing functions; manual ventilation can be performed by pressing the anesthetic gas reservoir in manual mode. 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: anesthetic drugs may cause constriction of smooth muscle of bronchi, resulting in bronchoconstriction, sudden cough or dyspnea, and severe cases resulting in exacerbation of the primary disease. 2. Stimulation and effects of anesthetic drugs on airways: the anesthetic can inhibit central and peripheral nerves, and if the administration speed is too high, the organism cannot tolerate the drugs possibly causing 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. Other: if the organism originally has respiratory diseases, such as allergic asthma, pneumonia and the like, the organism stress reaction can be caused by anesthesia, surgery and the like. 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.

In the inhalation type anesthesia operation process, when a patient suffers from cough and asthma, an anesthesiologist diagnoses that the patient is due to the stimulation and influence of the anesthetic on the airway of the patient and the influence of the anesthetic, the airway is contracted, bronchospasm is caused, the anesthesia administration of an anesthesia machine is stopped in time under the condition of the cough and asthma, a supporting treatment measure is adopted, a medical staff manually rotates a connecting shaft 2 to enable an atomization channel 5 on the connecting shaft 2 to be communicated with an air inlet and outlet channel 7, the atomization channel 5 is communicated with the inside of an air storage bag 3 through the air inlet and outlet 6, the left end of the atomization channel 5 on the connecting shaft 2 is connected with a medical atomizer through a quick connector, the tidal volume, the respiratory frequency and the positive pressure of inspiration are adjusted, the atomizer converts a medicine solution into tiny mist particles, mixed gas of the atomized medicine and air passes through the atomization channel 5, the mixed gas sequentially passes through the atomization channel 5 with the diameter gradually reduced from the air inlet end to the air outlet end, and then passes through a spiral channel 10, the mixed gas is formed, and enters a Maplon A respiratory circuit system, and the medical respiratory mask is matched with the face mask to directly affect the patient on the respiratory tract or the respiratory tract of the patient, and the relevant treatment measures are not needed to be carried out on the respiratory tract of the patient, and the treatment is carried out on the respiratory therapy by the patient in time, and the relevant measures is not needed; the medicine has high onset speed and is very important for relieving acute bronchospasm and airway inflammation. In the aerosol inhalation treatment process of the patient, medical staff observe and judge the spontaneous breathing state of the patient through the fluctuation of the air storage bag 3. The variable diameter structure of the atomizing channel 5 in the connecting shaft 2 is combined with the external spiral channel 10, so that the inlet pressure of the atomizer is reduced, the positive pressure atomizing ventilation capacity can be met by using a small atomizer, and the drug delivery efficiency can be improved; the atomized mixed gas enters a Mapleson A breathing circuit system, is inhaled by a patient through a breathing mask on the mouth and the face of the patient, directly acts on respiratory tracts and lungs, and the medicine is better absorbed and acts on lesion areas, so that the treatment effect is improved.
In the existing medical treatment, the problems existing in the use of the atomizer intervention in the humanized anesthesia stage are that: instrument technical complexity. 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: the effectiveness of the nebulizer in aerosolizing the drug delivery is affected by a variety of factors including the airflow rate and concentration set by the nebulizer, the condition of the breathing passageways, the breathing pattern of the 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. When the patient makes the next breath, the dead space gas in the previous breath is inhaled, and then the mixed gas of atomized medicine liquid and air delivered from the atomizer through the atomizing passage 5 and the spiral passage 10 at positive pressure is inhaled. On the atomizing channel 5, from the air inlet end to the air outlet end, the diameter of the channel is gradually reduced, and a spiral channel 10 with an inclination angle of 20 degrees is arranged, so that the airflow speed and the vortex effect of the atomizing gas are increased, the pressure of the mixed gas is improved, and the atomizing effect is improved. The radius of the turning part of the spiral channel 10 is 6 times of the inner diameter of the spiral pipe, so that the air flow resistance is reduced, atomized mixed air flow more smoothly passes through the turning part, the energy loss is reduced, and the air with larger flow can smoothly pass through the turning part without blocking or reducing the atomization effect. The atomized mixed air flow is accelerated after passing through the turning part, so that the air flow speed is further increased, the vortex effect is increased, the introducing concentration and the introducing speed of atomized liquid medicine are ensured, the atomization treatment effect is improved, and the atomization treatment requirement on a patient is met. The invention simplifies and overcomes the problems of complexity and unstable effect of the atomizing machine in atomization treatment in the humanized anesthesia stage. Under the condition that the original medical mode is not required to be destroyed, the air flow speed and the concentration of the mixed air flow of the atomized liquid medicine and the air can be ensured, the intervention is carried out in the Maplseon A system, and under the condition that the anesthesia machine stops supplying oxygen, the oxygen supply of a patient is ensured while supporting treatment is carried out. The atomizing machine normally lets in atomizing gas, through the reducing structure and the terminal spiral passageway of atomizing passageway, provides effective drug delivery and ventilation support, for the airway constriction, bronchospasm or anesthetic are to the stimulation and the influence of air flue, and the treatment that induces the respiratory disease that leads to cough and dyspnea provides better choice. Rapid drug delivery and ventilation support, improving patient condition.
The complexity of achieving positive airway pressure in existing medicine is as follows: selection and setting of devices. 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 adjusting: positive pressure ventilation 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 a MaplesonA system, the required atomization gas amount per minute is calculated according to the MaplesonA system, and the required atomization gas amount per minute is 1-2ml/kg according to the body weight. Such as: a patient weighing 70kg would require an amount of nebulization 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 end of a patient, when the patient exhales, the gas exhaled by the patient enters the air storage bag 3, and when the patient inhales, the air storage bag 3 contracts and fresh atomized gas and air are provided for the patient; the APL valve is positioned between the reservoir 3 and the patient end, and the resistance is adjusted as needed to control the flow of gas and end-tidal 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 atomizer with the cooperation of an atomizing channel and a spiral channel, the inspiration pressure and the tidal volume are ensured, and the breathing frequency can be observed through the fluctuation of the air storage bag; on the other hand, the invention is arranged in a Mapleson A system, can ensure the effective ventilation quantity of the atomized gas, and plays a role in treatment under the condition of ensuring the normal respiratory quantity.
The connecting shaft 2 can be provided with marks and indications which are easy for medical staff to clearly distinguish aiming at the oxygen channel 4 and the atomizing channel 5, so that the oxygen channel and the atomizing channel can be accurately switched in different scenes. The operation convenience is improved, and therapeutic measures are taken in a supporting manner in time. The medical staff can rapidly and accurately switch from the air bag air supply in the manual mode to the atomization treatment mode, so that the medical operation efficiency is improved.
