Description

An atomized drug delivery device

technical field

The utility model relates to the technical field of an atomized drug delivery device, in particular to a pipe-type atomized drug delivery device with an electronic atomization function.

Background technique

Drugs are given in a variety of ways, such as by mouth, intravenously (IV), intramuscularly (IM), or subcutaneously (subcutaneously). The drug may also be given sublingually (sublingual), rectal instillation (rectal administration), eye drops, nasal spray, oral spray (inhalation), or topically (topically) or systemically (transdermally) on the skin. Each route of administration has its own specific purpose and has its own advantages and disadvantages.

On the one hand, the oral administration method slows the drug effect; on the one hand, it will cause the irritation of the drug to the stomach; on the other hand, the first-pass effect of the liver will reduce the utilization rate of the drug. Administration methods other than oral administration are collectively referred to as administration outside the digestive tract, such as injection administration or inhalation administration.

Some drugs, such as gas anesthetics and nebulized anti-asthma drugs (quantitative supply in containers), etc., can be administered by inhalation. These drugs enter the lungs directly through the airways, where they are absorbed into the blood circulation. Only a few drugs are available this way. Inhaled drugs should be carefully monitored to ensure that the patient inhales the proper amount of drug over a specified period of time. Metered-dose inhalation systems are very useful because they can be installed directly on the path that supplies air to the lungs. Due to the large difference in the amount of drug inhaled into the blood by nebulization, this route is rarely used to treat diseases of tissues or organs other than the lungs.

Aerosols generally refer to preparations that produce droplets when heated or pressurized. In the field of medicine and pharmacy, aerosols refer to preparations that contain medicinal liquids, emulsions or suspensions that are sprayed out in the form of mist for lung inhalation or directly sprayed to the mucous membranes of the cavity, skin and space for disinfection. Aerosol administration has the following advantages: (1) The drug can directly go to the site of action or absorption, and has a very obvious quick-acting and localizing effect, especially in the respiratory tract, which has irreplaceable advantages of other dosage forms; (2) non-toxic Oral administration can reduce the irritation of the drug to the gastrointestinal tract and avoid the first-pass effect of the liver.

Usually inhalation aerosol should check droplet (particle) size distribution, usually inhalation aerosol requires that its average particle size should be controlled below 10 μm, preferably below 5 μm. The methods of liquid atomization include pressure atomization, turntable atomization, gas atomization and sonic atomization.
