Multi-Reservoir Pump Patch
First Claim
1. A drug delivery device comprising,a. a housing having a bottom surface configured to removably attach directly to a user'"'"'s skin;
- b. a medicament manifold contained within the housing;
c. a single dispense interface having a distal end and a proximal end, where the proximal end is fluidly connected to the manifold and the distal end protrudes through the housing and is configured for subcutaneous placement in a user'"'"' skin;
d. a first reservoir and a second reservoir each connected to the manifold; and
e. a pump connected to the first reservoir configured to continuously dispense a primary medicament contained in the first reservoir through the manifold into the proximal end of the single dispense interface and then out the distal end.

Abstract
A device to co-deliver at least two medicaments is disclosed where a first reservoir containing a primary medicament is connected to a manifold and cannula and where one or more additional reservoirs are placed in fluid communication with the manifold in parallel or inline flow. The additional reservoir(s) can be located within the device or as part of an attachable medicated module that connects to external port located on the device housing. Both medicaments are delivered through a cannula subcutaneously. The device is configured to be user wearable through attachment directly to the skin by an adhesive.

8. A drug delivery device comprising,
a. a housing having a bottom surface configured to removably attach directly to a user'"'"'s skin; -
b. a medicament manifold contained within the housing; c. a single dispense interface having a distal end and a proximal end, where the proximal end is fluidly connected to the manifold and the distal end protrudes through the housing; d. a first reservoir connected to the manifold; e. an attachment port on the housing configured for fluid communication with the manifold and to allow removable attachment of a medicated module containing a reservoir of secondary medicament, where the secondary medicament is placed in fluid communication with the manifold; and e. a pump connected to the first reservoir configured to continuously dispense a primary medicament contained in the first reservoir through the manifold into the proximal end of the single dispense interface and then out the distal end, where the secondary medicament in the manifold also flows through the proximal end of the single dispense interface.
