Respiratory medical clinical inhalation drug delivery device

Abstract

The invention relates to the technical field of a medical care appliance and particularly relates to a respiratory medical clinical inhalation drug delivery device. The device includes a bottle body,an injection bottle, a storage bottle and a nozzle, wherein the injection bottle and the storage bottle are fixed in the bottle body, a first gear and a second gear are fixed inside the bottle body, the first gear and the second gear are coaxially fixed together, a drug injection pipe and a drug discharge pipe are connected with the bottom of the injection bottle, an uplink one-way valve is arranged inside the injection pipe, a downlink one-way valve is arranged inside the drug discharge pipe, upper and lower rotating pieces are provided with two 90-DEG fan-shaped through holes diagonally, andthe two through holes are staggered from each other. The device is advantaged in that structure design is reasonable, drug solution in the storage bottle can be continuously inhaled into the injection bottle through continuously pressing a push handle, the drug solution in the injection bottle is discharged along the drug pipe with the certain pressure, through turning the nozzle, the width of apassage between an injection hopper and a discharge hopper can be changed, the jet amount of the drug liquid is controlled, and the jet speed of the drug liquid is adjusted.

Description

technical field [0001] The invention relates to the technical field of medical care appliances, in particular to a clinical inhalation drug delivery device for respiratory medicine. Background technique [0002] Department of Respiratory Medicine is a common department of modern Western medicine. It is commonly used to treat diseases of the lungs, trachea, bronchi and throat. There are various routes of drug administration in Respiratory Medicine, including oral, intravenous, and intramuscular injections, among which oral drugs are the most common. However, on the one hand, the effect of oral administration is slow, and the utilization rate of the drug decreases after the first-pass effect in the liver; on the other hand, the drug may stimulate the digestive system and cause gastrointestinal discomfort. In addition to oral administration, respiratory medicine often The administration method of inhalation is adopted, that is, part of the medicine generates mist droplets under...

Problems solved by technology

However, compared with the traditional inhalation drug delivery device, the biggest feature of this device is that it can avoid the problem of messy charging lines and difficult arrangement caused by traditional chargers, and rely too much on electric energy. If the battery is exhausted and cannot be charged in time Will not work properly, its internal drug discharge structure is not perfect
