Abstract

The invention discloses a transtracheal catheter spray administration device, and relates to the technical field of medical instruments. The tracheal catheter spray administration device solves the problems that an existing tracheal catheter spray administration device is incomplete in atomization function, affects drug effect exertion, depends on manual administration through an injector, cannotachieve continuous quantitative administration, wastes time and labor, is poor in administration precision, and easily causes discomfort to a patient. The transtracheal catheter spray administration device comprises a quantitative administration device, an atomization device and a transtracheal catheter assembly, wherein the quantitative administration device comprises a base, a motor, a pushing assembly, a transmission assembly, an injector, an injector fixing frame and two injector locking bolts, the atomization device is arranged on the base close to one side of the injector fixing frame, and the atomization device comprises a medicine storage tank, a medicine storage tank support, an atomizer, an air inlet atomization guide pipe, a universal adapter, an air outlet atomization guide pipe and a liquid inlet pipe. The device is used for realizing automatic spray administration of the tracheal catheter.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a spray drug delivery device through a tracheal catheter. Background technique [0002] Asthma is a life-threatening emergency disease. When treating asthma, directly acting on the trachea with a medicament containing therapeutic drug ingredients is one of the most effective therapeutic methods. When the patient is awake, the patient can actively inhale the medicine, but when the patient is unconscious or under anesthesia, the medicine cannot be inhaled. The current commonly used method is to use an endotracheal tube spray delivery device to spray the medicine. In the treatment of asthma, on the one hand, the atomization effect of the drug is a very critical factor affecting the time-effectiveness of asthma treatment. The more complete the atomization of the drug for the treatment of asthma, the smaller the atomized particles formed, and the more timely the drug effect wi...
