Abstract

The invention discloses an atomized drug delivery device for respiratory internal medicine with adjustable drug delivery speed, and specifically relates to the field of drug delivery devices, including a feeding housing, an atomizing housing, an adjusting housing and a drug outlet mouth. The bottom of the shell is fixed with a base, the inside of the feeding shell is provided with a storage compartment, the inside of the storage compartment is provided with a medicine bottle, the inside of the atomization shell is provided with an atomizing nozzle, and the bottom of the atomizing nozzle is connected to There are filter cotton straws and atomizing sheets on the top, spring pads for fixing medicine bottles are provided at the four corners of the bottom of the atomizing shell, and a feed heating channel that runs through the upper and lower surfaces of the atomizing shell is provided inside the regulating shell . The invention works through the screw rod, and the slider drives the connecting rod and the adjustment block to move up and down. When the adjustment block moves up and down, it can cooperate with the external heating plate to increase or decrease the volume of the medicine in the feeding heating channel. At this time, the adjustment block The medicine pressure at the bottom is increased or decreased, so as to realize the multi-level adjustment of the medicine ejection speed.

Description

technical field [0001] The invention relates to the technical field of drug delivery devices, and more specifically, the invention relates to an atomized drug delivery device for respiratory medicine whose drug delivery speed can be adjusted. Background technique [0002] Aerosols usually refer to preparations that can produce mist droplets under heat or pressure. In the field of medicine and pharmacy, aerosols refer to liquids, emulsions or suspensions containing medicines that are sprayed out in the form of mist when used. , used for lung inhalation or directly sprayed to the mucous membrane of the cavity, skin and space disinfection, aerosol administration has the following advantages: the drug can directly go to the action site or absorption site, and has a very obvious quick-acting and localizing effect. Especially in respiratory tract administration, it has irreplaceable advantages of other dosage forms; non-oral administration can reduce the irritation of the drug to ...
