Title:
ATOMIZATION TRIGGER STRUCTURE, AND ATOMIZER HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2023/125466
Kind Code:
A1
Abstract:
An inspiratory trigger atomizer for a patient with an airway disease, which belongs to the technical field of medical devices. The inspiratory trigger atomizer for a patient with an airway disease comprises: a main body comprising an atomization module (4) and a nozzle connected to the atomization module (4); an atomization driver provided on the atomization module (4); an air pressure sensor arranged in the atomization module (4) and electrically connected to the atomization driver; and a gas guide channel (10), which is arranged in the main body and has a first end located in the nozzle and a second end arranged at a monitoring end of the air pressure sensor. The air pressure sensor can acquire the information regarding air pressure in the nozzle that changes with the patient's inhalation and exhalation via the gas guide channel (10), and then identify the inhalation state of the patient and generate a corresponding signal to trigger a main unit module (11) to start the atomization driver. The inspiratory trigger atomizer for a patient with an airway disease has an extremely short inspiratory trigger response time, such that atomization can be quickly triggered after the patient inhales, and with the design of the atomization duration being 1.5 s, the patient can fully inhale a drug, so that the inspiratory trigger atomizer can be applied to a wide range of people.
