Direct-From-Vial Medication Transfer Device

A medication transfer device comprising:

• a first mechanical interface on a first end having a shape and size to securedly couple the medication transfer device to an infusion pump;
• a second mechanical interface on a second end opposite the first end having a shape and size to secure a vial containing medication;
• a single piercing element extending from the second end and defining both at least a portion of (i) an inlet channel in fluid communication with a pressure source generated by the infusion pump when the first interface is coupled to the infusion pump and (ii) an outlet channel in direct fluid communication with an infusion set delivering medication from the vial to a patient, the outlet channel providing a direct-from-vial infusion path in which medication is delivered from the vial directly to a patient without transfer to an intermediary container;
• wherein the medication transfer device is disposable and intended for one-time use.

A medication transfer device comprising:

• a vial transfer adapter having a unitary housing with (i) a first interface on a first end configured to mechanically couple the medication transfer device to an infusion pump and (ii) a second interface on a second end opposite of the first end configured to secure a vial containing medication;
• and
• a single piercing element configured to pierce a stopper of the vial and defining at least a portion of both (iii) an inlet channel in fluid communication with a pressure source of the infusion pump and (iv) an outlet channel in direct fluid communication with an infusion set for delivering medication from the vial to a patient, the single piercing element comprising multiple side openings at different axial positions configured to facilitate evacuation of substantially all liquid from the vial when inverted;
• wherein the outlet channel provides a direct-from-vial infusion path in which medication is delivered from the vial directly to a patient without transfer to an intermediary container, and wherein the medication transfer device is disposable and intended for one-time use.

A medication infusion system comprising:

• a housing defining a medication container adapter interface;
• a pressure source within the housing;
• a control unit in communication with the pressure source;
• and
• a medication transfer device having a unitary housing shaped to mechanically interface with the medication container adapter interface and to secure a vial, the medication transfer device including a single piercing element configured to pierce a stopper of the vial and defining at least a portion of both (i) an inlet channel coupled to the pressure source and (ii) an outlet channel directly couplable to an infusion set;
• wherein, when the pressure source is active, gas is expelled through the inlet channel into the vial to displace medication from the vial through the outlet channel for delivery to a patient via a direct-from-vial infusion path without transfer to an intermediary container.
