What is a type of needle specifically designed to draw up liquid from an ampule?

The type of needle designed specifically to draw up liquid from an ampule is the filter needle. This needle incorporates a filter in its design to prevent any glass particles from entering the syringe when drawing up medication from an ampule. Ampules are made of glass and can break, creating tiny shards when opened, which could contaminate the medication. A filter needle helps ensure that only the liquid medication is drawn into the syringe, promoting safety and accuracy in medication preparation.

In contrast, a ventilated needle is primarily designed for providing airflow during certain types of injections, and a luer-lock needle is used to create a secure connection between the syringe and the needle, but it doesn’t have the filtering capability of the filter needle. A curved needle is typically associated with specific types of injections or procedures, such as those requiring a more precise angle of insertion, but it is not intended for drawing from ampules. Understanding the unique functions of these needles is key for a pharmacy technician when preparing medications safely.
