Single and multi-dose nebulizer device
There were many mechanisms for taking the drug by inhalation, and the mechanisms and methods of administration differed, and there was great competition in efficacy and giving an accurate dose of one hundred percent.
There are medicines that are given in one dose only, and there are multi-dose devices that contain numbered doses, for example 8 doses that the patient feels when taking them as a number.
Single-capsule gelatinous device:
It is a device in which a hard, gelatinous capsule is placed in a suitable place where it is pierced on both sides to facilitate its exposure to a certain pressure and the release of the substance from inside it into the respiratory tract.
The air flows from the first hole to create a vibrating air that makes the powder come out smoothly heading its way and causing a therapeutic response.
Multi dose device (foil blisters):
It is a metal disc that contains eight or four holes, often filled with medication powder and drug-carrying materials that help release it from the device into the oral cavity and inhale it more easily without affecting the effectiveness of the active ingredient.
What carrier material is added?
Coarse lactose is added to prevent physical and chemical interaction between the parts of the powder while it is in the mixture before launching (caking, adhesion, etc.).
Air is mechanically compressed into each hole in the aluminum disc to release its contents. The powder spreads and the patient then begins to inhale in an attempt to draw the entire dose into the lungs.
Of course, the metal holes are numbered or contain symbols to make it easier for the patient to know how many doses are remaining.
What is a spacer tube?
It is a tube used to reduce the number of daily doses by delivering the largest possible amount of medication to the lungs at a slower pace
Children cannot take these inhalers in this way, so we need a face mask for better administration, where the mask placed over the nose and mouth is completely attached to the spacer tube to reduce discomfort to the child.
