The medicament pump cartridge may include an electromagnetic pumping mechanism, wherein the electromagnetic pumping mechanism includes at least one magnet secured to a membrane. Further, the medicament pump cartridge may include an electromagnetic valve operably coupled to the electromagnetic pumping mechanism. The pump cartridge may be configured to allow for secured refills through compatible ports. The pump cartridge may include light indicators for ports/orifice that communicate with pump, and possess sensor volumetric feedback for continuous monitoring of the medicament volume. ## Claims ### Claim 1 A medicament pump cartridge, comprising: a reservoir configured to store a medicament, wherein the reservoir is configured to transition between an expanded configuration when filled with medicament and a collapsed configuration when empty; an electromagnetic pumping mechanism, wherein the electromagnetic pumping mechanism includes at least one magnet secured to a membrane; and an electromagnetic valve operably coupled to the electromagnetic pumping mechanism. ### Claim 2 (depends on 1) The medicament pump cartridge of claim 1, wherein the reservoir includes a plurality of reservoirs. ### Claim 3 (depends on 2) The medicament pump cartridge of claim 2, further comprising a rigid divider disposed between the plurality of reservoirs. ### Claim 4 (depends on 2) The medicament pump cartridge of claim 2, wherein each of the plurality of reservoirs includes a unique medicament. ### Claim 5 (depends on 1) The medicament pump cartridge of claim 1, further comprising a first volumetric flow rate sensor system configured to provide feedback pump control and cartridge fault detection. ### Claim 6 (depends on 5) The medicament pump cartridge of claim 5, further comprising a secondary volumetric flow rate sensor system disposed downstream of an outlet of the pumping mechanism. ### Claim 7 (depends on 1) The medicament pump cartridge of claim 1, further comprising a port configured to allow refilling of the reservoir. ### Claim 8 (depends on 7) The medicament pump cartridge of claim 7, wherein the port is configured to prevent unauthorized refilling. ### Claim 9 (depends on 1) The medicament pump cartridge of claim 1, further including at least one sensor. ### Claim 10 (depends on 9) The medicament pump cartridge of claim 9, wherein the at least one sensor is configured to measure a temperature of one of the medicament disposed in the reservoir and a surrounding of the medicament pump cartridge. ### Claim 11 (depends on 9) The medicament pump cartridge of claim 9, wherein the at least one sensor is configured to measure one of a stress or strain in a wall of the reservoir. ### Claim 12 (depends on 1) The medicament pump cartridge of claim 1, further comprising a collapse mechanism configured to promote collapsing of the reservoir. ### Claim 13 (depends on 12) The medicament pump cartridge of claim 12, wherein the collapse mechanism includes at least one resilient member. ### Claim 14 (depends on 12) The medicament pump cartridge of claim 12, wherein the collapse mechanism includes at least one roller configured to roll over collapsed portions of the reservoir. ### Claim 15 (depends on 1) The medicament pump cartridge of claim 1, further comprising a case having a transparent window. ### Claim 16 (depends on 1) The medicament pump cartridge of claim 1, further comprising a memory configured to store information. ### Claim 17 (depends on 16) The medicament pump cartridge of claim 16, wherein the information includes at least an age of the medicament. ### Claim 18 (depends on 1) The medicament pump cartridge of claim 1, wherein the reservoir includes a plurality of walls, wherein at least a portion of one of the walls is thicker relative to the remaining walls. ### Claim 19 (depends on 18) The medicament pump cartridge of claim 18, wherein the one of the walls includes a tapering thickness. ### Claim 20 (depends on 1) The medicament pump cartridge of claim 1, wherein the pump cartridge is disposable. ### Claim 21 A medication pump cartridge, comprising: a case defining a cavity therein, wherein a wall of the case includes a transparent window; a reservoir configured to store a medicament, wherein the reservoir is configured to transition between an expanded configuration when filled with medicament and a collapsed configuration when empty; a pump configured to facilitate delivery of medicament from within the reservoir to a patient; a memory configured to store information including an age of the medicament; a temperature sensor configured to measure a temperature of the medicament; and a collapse mechanism configured to promote collapsing of the reservoir, wherein the collapse mechanism includes at least one resilient member. ### Claim 22 (depends on 21) The medicament pump cartridge of claim 21, wherein the reservoir includes a plurality of reservoirs. ### Claim 23 (depends on 22) The medicament pump cartridge of claim 22, wherein each of the plurality of reservoirs includes a unique medicament. ### Claim 24 (depends on 21) The medicament pump cartridge of claim 21, wherein the reservoir includes an internal wall defining a plurality of medicament chambers. ### Claim 25 (depends on 24) The medicament pump cartridge of claim 24, wherein the internal wall extends at an angle of approximately 45 degrees relative to a longitudinal wall of the reservoir. ### Claim 26 (depends on 24) The medicament pump cartridge of claim 24, wherein one of the plurality of medicament chambers includes a volume that is larger than a volume of another of the plurality of medicament chambers. ### Claim 27 (depends on 24) The medicament pump cartridge of claim 24, wherein the internal wall includes an integrated pressure sensor. ### Claim 28 (depends on 25) The medicament pump cartridge of claim 25, wherein the plurality of chambers are in fluid communication with one another via an opening in the internal wall. ### Claim 29 (depends on 28) The medicament pump cartridge of claim 28, wherein the opening is operably coupled to a valve configured to control a flow of fluid through the opening.
