Both fluids and/or medicaments are delivered via a single dispense interface. ## Claims ### Claim at position 1 1-18. (canceled) ### Claim 19 A drug delivery system for delivering at least two medicaments, comprising: a pump operably connected to a first reservoir containing a first fluid or medicament; a delivery tube, wherein an end of the delivery tube is connected to the first reservoir; a dispense interface in fluid communication with the delivery tube; and a secondary module in fluid communication with the delivery tube, wherein the secondary module comprises (i) a bypass channel for delivery of the first fluid or medicament, (ii) a second reservoir containing a second fluid or medicament, (iii) a proximal needle, (iv) a distal needle, and (v) an actuation button, wherein the actuation button is configured to permit delivery of the first fluid or medicament when the actuation button is in a non-actuated position and selectively permit delivery of the second fluid or medicament when the actuation button is in an actuated position. ### Claim 20 (depends on 19) The drug delivery system of claim 19, wherein, when the actuation button is in the non-actuated position, the proximal and distal needles are in fluid communication with the bypass channel. ### Claim 21 (depends on 19) The drug delivery system of claim 19, wherein, when the actuation button is in the actuated position, the proximal and distal needles are in fluid communication with the second reservoir. ### Claim 22 (depends on 19) The drug delivery system of claim 19, wherein the delivery tube is connected to the first reservoir via a hub. ### Claim 23 (depends on 19) The drug delivery system of claim 19, wherein, when the actuation button is in the non-actuated position, the first fluid or medicament can be delivered via the bypass channel. ### Claim 24 (depends on 19) The drug delivery system of claim 19, wherein the actuation button is actuated by sliding the button, the actuation button comprises at least one snap arm configured to engage at least one groove in an inner surface of a housing of the secondary module, the proximal needle is fixed to the actuation button and the at least one groove corresponds to the actuated position of the actuation button. ### Claim 25 (depends on 24) The drug delivery system of claim 24, wherein the at least one groove corresponds to the actuated position of the actuation button. ### Claim 26 (depends on 25) The drug delivery system of claim 25, wherein the secondary module is configured to prevent the actuation button from being reversed to the non-actuated position after actuation. ### Claim 27 (depends on 19) The drug delivery system of claim 19, wherein the secondary module is located near the end of the delivery tube that is connected to the first reservoir. ### Claim 28 (depends on 19) The drug delivery system of claim 19, wherein the secondary module is located at a position between the end of the delivery tube that is connected to the first reservoir and the dispense interface. ### Claim 29 (depends on 19) The drug delivery system of claim 19, wherein the secondary module is located near the dispense interface. ### Claim 30 (depends on 19) The drug delivery system of claim 19, wherein the secondary module in fluid communication with the delivery tube comprises a re-usable secondary module. ### Claim 31 (depends on 19) The drug delivery system of claim 19, wherein the secondary module is releasably coupled to a hub. ### Claim 32 A drug delivery system for delivering at least two fluids and/or medicaments, comprising: a pump operably connected to a first reservoir containing a first fluid and/or medicament; a delivery tube, wherein an end of the delivery tube is connected to the first reservoir; a dispense interface in fluid communication with the delivery tube; and a secondary module in fluid communication with the delivery tube, wherein the secondary module comprises a housing and an actuation button that includes (i) a chamber for a cartridge containing a second fluid and/or medicament and (ii) a bypass channel for delivery of the first fluid and/or medicament, wherein the actuation button is configured to permit delivery of the first fluid and/or medicament when the actuation button is in a non-actuated position and selectively permit delivery of the second fluid and/or medicament when the actuation button is in an actuated position. ### Claim 33 (depends on 32) The drug delivery system of claim 32, wherein, when the actuation button is in the non-actuated position, the cartridge is laterally offset from the delivery tube, and wherein, when the actuation button is in the actuated position, the cartridge is aligned with the delivery tube. ### Claim 34 (depends on 32) The drug delivery system of claim 32, wherein the cartridge comprises at least one one-way valve that is configured to open when the cartridge is aligned with the delivery tube and the first fluid and/or medicament is pumped through the delivery tube, thereby allowing the second fluid and/or medicament to be delivered. ### Claim 35 A drug delivery system for delivering at least two fluids and/or medicaments, comprising: a pump operably connected to a first reservoir containing a first fluid and/or medicament; a delivery tube, wherein an end of the delivery tube is connected to the first reservoir; a dispense interface in fluid communication with the delivery tube; and a secondary module in fluid communication with the delivery tube, wherein the secondary module comprises a housing and a rotary member that includes (i) a chamber for a cartridge containing a second fluid and/or medicament and (ii) a bypass channel for delivery of the first fluid and/or medicament, wherein the rotary member is configured to permit delivery of the first fluid and/or medicament when the bypass channel is aligned with the delivery tube and selectively permit delivery of the second fluid and/or medicament when the cartridge is aligned with the delivery tube. ### Claim 36 (depends on 35) The drug delivery system of claim 35, wherein the cartridge comprises at least one one-way valve that is configured to open when the cartridge is aligned with the delivery tube and the first medicament is pumped through the preliminary tube, thereby allowing the second medicament to be delivered.
