TECHNICAL FIELD
[0001] The present application relates to the technical field of atomization treatment devices, in particular to a lung cancer atomization breathing treatment auxiliary device. BACKGROUND
[0002] Atomization treatment is a common method for lung cancer treatment. As the disease progresses, lung cancer can cause local atelectasis in the lungs, forming obstructive pneumonia, and symptoms such as fever, repeated cough and sputum, blood in sputum, and even difficulty breathing. At this time, atomization treatment can effectively relieve related symptoms and is beneficial to the subsidence of lung inflammation. Atomization treatment mainly converts drugs into atomized particles through ultrasonic emulsification and directly inhales them into the lungs to achieve the purpose of humidifying the airway, eliminating airway inflammation, and reducing and eliminating sputum. The main drugs include meizothrombin for injection, budesonide suspension for inhalation, and compound betamethasone injection, etc. When the trachea is compressed by lung cancer, there will be obvious symptoms of limited tracheal sputum discharge and thick sputum. Atomization can effectively thin the sputum and promote sputum discharge. For some lung cancer patients who can undergo surgical resection, preoperative atomization can fully prepare the respiratory tract and help increase the reserve of lung function. Postoperative atomization is beneficial to sputum discharge, reduces lung inflammation, and is beneficial to the recovery of lung cancer patients after surgery. Therefore, lung cancer patients can undergo atomization treatment, and atomization treatment is beneficial to the improvement of respiratory function for both lung cancer patients who can undergo surgical resection and those who cannot undergo surgery. Therefore, a lung cancer atomization breathing treatment auxiliary device is used.
[0003] The insulin atomization administration device disclosed in patent No. 201610941705.2 includes a shell, a medicine bottle, an ultrasonic circuit for controlling the administration dose, a medicine guide rod, a medicine guide rod inlet, a sealing gasket, an air flow switch, an air passage, a microporous ultrasonic atomization sheet, a medicine mist suction nozzle, a microporous atomization sheet, and an atomization area. The technical solution has the following problems: First, the device does not have a separate air inlet, and the medicine mist suction nozzle is used to inhale the medicine into the oral cavity. Under the action of suction, the air flow switch is closed, the microporous ultrasonic atomization sheet works, the medicine mist is sprayed, and the air mainly enters from the air inlet of the air flow switch. Since the air inlet of the air flow switch is small, the amount of air entering the medicine mist suction nozzle cannot meet the requirements of mixing and flowing of the medicine mist in the medicine mist suction nozzle, oral cavity, and trachea, so part of the medicine mist is formed into large medicine mist particles in the medicine mist suction nozzle, oral cavity, and trachea, and adheres and stays in the medicine mist suction nozzle, oral cavity, and trachea, failing to enter the lungs. Second, the atomization administration dose in the technical solution is determined by the working time of the microporous ultrasonic atomization sheet, and the atomization amount of the microporous ultrasonic atomization sheet has errors, so precise atomization administration cannot be achieved.
