A slender flexible tube with a blunt distal end intended to be attached to a syringe to aspirate pharmaceutical fluids from an open vial or ampule during the preparation of medications performed by healthcare professionals (e.g., pharmacists, physicians, nurses); it is not intended to puncture the seal of a vial/container. It is typically made of plastic and may include an integral filter intended to retain micro-particles to reduce the risk of particle contamination of the patient medication. It is not intended for skin injections or tissue manipulation and is not intended for enteral use. This is a single-use device.
