Description

Technical Field

[0001] The present invention relates to the technical field related to ventilators, and in particular to an atomizing heater for ventilators. Background Art

[0002] ICU patients often require nebulization therapy for various reasons. This is especially true for patients with artificial airways undergoing mechanical ventilation who often experience asthma, thick sputum, and laryngeal edema. Nebulization can help relieve airway spasms and asthma, reduce inflammation and mucosal edema to prevent and treat infection, and dilute thick sputum for easier clearance, thereby clearing the airways. However, nebulization therapy currently requires different nebulizer devices for patients with and without artificial airways, and for those with and without artificial airways undergoing mechanical ventilation. Patients on ventilators who require nebulization must currently purchase dedicated modules from the manufacturer. These modules can cost between 30,000 and 60,000 yuan, making them prohibitively expensive. This significantly inconveniences clinical patients and the need to configure different nebulizer devices to accommodate patients at different stages of their illnesses incurs additional costs for both patients and departments, increasing both departmental costs and the burden on patients.

[0006] Solid medicine and water or liquid medicine are placed in a stirring device. After the stirring device stirs the medicine, it cooperates with the atomizing device to heat the medicine, so that the medicine is heated to generate gas. The gas is sprayed into the respiratory tract under the joint action of the heating rod and the heating spray sheet. The mist is discharged from the outside of the shell through the respiratory tract to perform atomization treatment on the patient. When the human body inhales the mist and discharges it from the atomizing device, the exhaust device is in a closed state. When exhaling, the atomizing device is closed and the exhaust device is opened to discharge the waste. After the work is completed, the water pump device is used to clean the inside of the stirring device to ensure the hygiene and safety of the atomizing device.

The temperature of the gas will drop when it moves from the stirring device to the intake pipe, and the heating rod will heat it in time to facilitate the gas to move to the top of the atomizer box. When the gas passes through the filter membrane on the base, the filter membrane absorbs and filters the drug particles that may be contained in the gas to avoid clogging of the heating spray sheet. This design optimizes the functionality of the atomizer device.

[0033] like Figure 1As shown, the outlet end of the expiratory tube 5 is placed inside the exhaust device 7, the exhaust device 7 includes an adsorption box 9 and an exhaust pump 10, the air inlet end of the expiratory tube 5 is in contact with the respiratory channel 4, the air outlet end of the expiratory tube 5 is connected to the filter 8, the adsorption box 9 is arranged below the filter 8 and is connected to the expiratory tube 5, the exhaust pump 10 is installed below the adsorption box 9, the main controller 12 is connected to the exhaust pump 10, and the exhaust pump 10 is provided with an exhaust pipe 11, one end of the exhaust pipe 11 is connected to the exhaust pump 10, and the other end of the exhaust pipe 11 is connected to the outside of the shell 1.

[0034] Solid medicine and water are placed into the funnel 23 through the liquid inlet pipe 24, and the main controller 12 controls the stirrer 15 to work. The stirring shaft 14 on the stirrer 15 stirs the liquid in the funnel 23 to fully dissolve the medicine, or the liquid medicine is directly flowed into the funnel 23 through the liquid inlet pipe 24 for stirring. After stirring, the main controller 12 controls the preheater 13 to preheat the medicine so that the medicine generates gas after heating, thereby causing the gas to move into the intake pipe 25. After sensing the gas in the stirring device 22, the sensor 57 in the intake pipe 25 transmits the information to the sub-controller 58, and the sub-controller 58 controls the air extraction. The pump 59 is working, and the gas moves from the stirring device 22 to the suction pipe 25 under the action of the vacuum pump 59.

Due to the gas The temperature will drop during the movement from the stirring device 22 to the air inlet pipe 3, and the heating rod 29 heats it in time, so that the gas can move to the top of the atomizing box 28. Since the diameter of the heating spray piece 27 is smaller than the diameter of the base 32, the atomizing chamber gradually narrows from the base 32 to the direction of the heating spray piece 27, thereby gathering the gas in the direction of the heating spray piece 27 while heating it, so that the heating spray piece 27 can further heat the gas to form a fine mist. When the gas passes through the filter membrane 31 on the base 32, the filter membrane 31 absorbs and filters the drug particles that may be contained in the gas. After the gas is sprayed out from the atomizing device 2, When the air moves from the intake pipe 3 to the breathing passage 4, the sub-controller 3 42 controls the motor 43 to work. The motor 43 is a forward and reverse motor 43. When the motor 43 moves forward, the left telescopic assembly 36 moves in a direction away from the breathing passage 4, so that the gas moves from the intake pipe 3 to the breathing passage 4.
