MEDICATION DELIVERY SYSTEM
First Claim
1. A medication delivery system comprising:
- an array of cartridge-receiving ports, each port comprising a fluid channel terminating at a fluid outlet, each port for receiving one of a plurality of cartridges, each cartridge containing a bolus volume of medication;
a medication-receiving fluid conduit fluidically coupled to the fluid outlet of each cartridge-receiving port at a first region and to a system outlet conduit at a second region, wherein the system outlet conduit is adapted to be coupled to a patient catheter line; and
a plurality of dispensing elements, each dispensing element corresponding to a single cartridge-receiving port, wherein upon activation of the dispensing element at least a portion of the bolus volume of medication flows through the fluid outlet of each cartridge-receiving port into the medication-receiving fluid conduit.

Abstract
A medication delivery system includes an array of cartridge-receiving ports, a medication receiving fluid conduit, and a plurality of dispensing elements. Each port includes a fluid channel terminating at a fluid outlet and is configured to receive one of a plurality of cartridges that each contain a bolus volume of medication. The medication-receiving fluid conduit is fluidically coupled to the fluid outlet of each cartridge-receiving port at a first region and to a system outlet conduit at a second region (which in turn can be coupled to a patient catheter line). Each dispensing element corresponds to a single cartridge-receiving port so that, upon activation of the dispensing element, at least a portion of the bolus volume of medication flows through the fluid outlet of each cartridge-receiving port into the medication-receiving fluid conduit. Related apparatus, systems, and methods are also disclosed.
