Abstract
A method and apparatus are disclosed that allow more efficient volume use of a reservoir used in medical infusion devices, such as insulin pumps. The invention provides for having a full reservoir and a full tubing composite when infusion of medication into a patient begins, allowing a volume of medicine substantially equal to the volume of medication in the full reservoir to be infused into the patient.
Claims7
A method of making a quantity of medication, substantially equal to the total volume of a reservoir in a medical infusion device, available for infusion into a patient, comprising the steps of:
- filling substantially all of the volume of said reservoir with a first quantity of medication;
- filling substantially all of the volume of a tubing composite with a second quantity of medication;
- and
- coupling the tubing composite to the reservoir wherein the step of filling substantially all of the volume of said tubing composite with said second quantity of medication further comprises the steps of:
- drawing medication into the tubing composite from a distal end of the tubing composite;
- attaching a quick-release syringe to the distal end of the tubing composite;
- coupling a proximal end of the tubing composite to the reservoir;
- inserting a needle portion of the quick-release syringe into a vial of medication;
- and
- actuating a piston portion of the reservoir to draw medication from the vial of medication, through the quick-release syringe, and fill substantially all of the tubing composite.
