How to use ampoules
Problems that may occur when using ampoules
Powder ampoules are used to dispense injectable powder or crystalline drugs, so the neck of the bottle is thick or flared to facilitate the loading of drugs. The body of the bottle is as thick as the neck, and a groove is blown at the connection between the neck and the body, which can be sawed open and injected after dissolving with solvent. This kind of ampoule is inconvenient to use. In recent years, a kind of injection container that can contain both powder and solvent has been developed, the container is divided into two chambers, the lower compartment contains sterile drug powder, the upper compartment contains solvent, the middle is separated by a special septum when the top plug is pressed down, the septum is opened, the solvent flows into the lower compartment, the drug is dissolved and used. This kind of container for injection is especially suitable for drugs that are unstable in solution.
Before opening, cut a scratch on the neck of the bottle with an abrasive wheel, disinfect the neck of the bottle, turn the nipple upward so that all the drug flows into the bottle, and then break the neck of the bottle. For easy-to-fold ampoules, the manufacturer's pre-cut part is marked at the nipple, and the nipple can be broken directly according to this direction.
Notice: If the ampoule is small in size, the nipple may not flow to the bottom automatically due to insufficient pressure, which may cause accidents when opening. It is necessary to flick or gently shake the nipple by hand for the drug solution to flow down smoothly. Generally, you need to pay attention to such problems when using ampoules with a diameter less than 7mm or a capacity of less than 2mL.
l Defective ampoules or incorrect handling may result in breaking the nipple or even the bottle when opening the ampoule, resulting in injuries to medical personnel and possible contamination by glass fragments falling into the drug solution.
l Glass and abrasive particles from the ampoule opening process can also lead to contamination of the solution.
l When a straight-necked ampoule is broken by a nurse, many glass fragments, which are not visible to the naked eye, will fall into the medicine, causing platelet rupture in the recipient, which can even cause death if the particles enter the heart with the blood. The curved-neck ampoule is easy to break and has a neat cut with fewer glass fragments, making it the only medical ampoule allowed to be used at present.
