Which system facilitates the direct attachment of a vial to a bag of diluent?

The Minibag Plus system is specifically designed to facilitate the direct attachment of a vial to a bag of diluent, which significantly streamlines the process of compounding sterile preparations. This system promotes a closed system for the transfer of medications, reducing the risk of contamination and improving the efficiency of the compounding process. With Minibag Plus, the user can easily connect a medication vial to a diluent bag, allowing for straightforward mixing and preparation. This method not only enhances safety but also minimizes waste during the compounding procedure.

In contrast, IV admixtures refer to the general process of preparing intravenous doses by mixing a drug with a IV fluid, but they do not specifically denote a system designed for direct attachment. Standard syringes are used for drawing up medications but do not allow for the direct transfer of a vial to a bag. Pill organizers are unrelated to sterile compounding and are used for organizing oral medications. Thus, the unique design and purpose of the Minibag Plus make it the correct answer in this context.
