1. A medication infusion set comprising:
- a base tube having an exterior surface, a proximal end, a distal end, and a first and second inner lumen extending between the proximal and distal ends, the base tube formed of a material selected from the group consisting of polyethylene and polypropylene;
a first rigid cannula having a proximal end, a distal end, and a lumen extending between the proximal and distal ends, the cannula proximal end positioned in of the first base tube lumen at the proximal end forming a fluid communication path from rigid cannula proximal end to the first inner lumen of the base tube;
a second rigid cannula having a proximal end, a distal end, and a lumen extending between the proximal and distal ends, the cannula proximal end positioned in of the second base tube lumen at the proximal end forming a fluid communication path from rigid cannula proximal end to the second inner lumen of the base tube;
an infusion catheter and infusion hub having merging chamber at the distal end of the base tubes that directs the fluid from the first and second inner lumen to the infusion cannula in the distal end of the infusion hub.

Abstract
The present invention relates to a disposable injection set that offers the ability for the patient to infuse from two prefilled medication cartridges without compromising the sterility of medication to be infused. Also, utilization of prefilled medication cartridges to provide a source of infusion material makes it easy and convenient to use by the average patient who must inject themselves with a varying mixture of insulin or medication.
