Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] Such as figure 1 , figure 2 As shown, the present invention includes a casing 10 and a suction nozzle 2 disposed on one side thereof, and the casing 10 houses a battery 1 , a liquid supply bottle 3 and an atomizer 5 . The liquid supply bottle 3 has a porous structure or a fiber structure and can be replaced; one end of the liquid supply bottle 3 communicates with the suction nozzle 2 , and the other end contacts the atomizer 5 , and an air channel 12 is opened on the outer surface of the liquid supply bottle 3 . There is an air inlet on the housing 10 above the atomizer 5 , and an air filter 9 is provided at the inlet, through which the inhaled external air enters the housing 10 after being filtered. A gas-liquid isolation membrane 8 is arranged between the air inlet and the atomizer to separate the liquid medicine and the air, so that the whole dev...

Abstract

The invention relates to a medical device for alveolar absorption of medicine, in particular to an intrapulmonary drug delivery device that atomizes medicine dissolved in liquid into particles that can reach deep into the alveoli. The suction nozzle is equipped with a battery, a liquid supply bottle and an atomizer in the shell, wherein: one end of the liquid supply bottle is connected with the suction nozzle, and the other end is connected with the atomizer. The air inlet has an air channel on the outer surface of the liquid supply bottle; an action switch is installed on the shell. The invention has uniform atomization, small atomized particles, and an average diameter of up to about 1 micron, which is the best technical parameter for intrapulmonary absorption; the provided quantitative device can control the dosage. The present invention can be used for administration in capillaries and alveoli.

Description

technical field [0001] The invention relates to a medical device for alveolar absorption of medicine, in particular to an intrapulmonary drug delivery device that atomizes medicine dissolved in liquid into microparticles that can reach deep into alveoli. Background technique [0002] Most of the existing intrapulmonary drug delivery devices for medical purposes are divided into high-pressure gas tank spray devices and ultrasonic atomization devices, which are currently widely used in clinics and homes to make the alveoli absorb drugs. Although the existing intrapulmonary drug delivery device represents a technological development stage, it also has defects such as being inconvenient to carry, the atomized particles are too large, and the inhalation amount of the atomized agent is uncontrollable. Contents of the invention [0003] The object of the present invention is to provide an intrapulmonary drug delivery device. When using the drug delivery device, the atomized parti...
