Formulation delivery priming methods

A method of priming a formulation delivery device, the method comprising:

• providing a formulation cartridge configured to store a first formulation and a second formulation;
• inserting the formulation cartridge into a handle of the formulation delivery device, such that the formulation cartridge fluidically couples the first formulation and the second formulation to a formulation dispensing assembly of the formulation delivery device, wherein the formulation dispensing assembly comprises a nozzle assembly, at least one pump fluidically coupled to the nozzle assembly, and a controller operably connected to the pump;
• initiating a priming sequence of the formulation delivery device, wherein the priming sequence comprises simultaneously pumping the first formulation and the second formulation with the at least one pump for a first time period such that the first formulation and the second formulation pass from the formulation cartridge, through the at least one pump, and exit the nozzle assembly,
• wherein initiating the priming sequence comprises executing a priming actuation sequence of a button disposed on the handle, wherein the priming actuation sequence comprises pressing the button in a predetermined pattern within a third time period.

A formulation delivery system, comprising:

• a formulation cartridge configured to store a first formulation and a second formulation in a first formulation packet and a second formulation packet, respectively;
• and
• a handle configured to reversibly receive the formulation cartridge, wherein the handle houses a formulation dispensing assembly comprising a nozzle assembly, at least one pump fluidically coupled to the nozzle assembly, and a controller operably connected to the pump, wherein the controller comprises a processor and a data store storing logic, which when executed by the processor, executes a priming sequence comprising simultaneously pumping the first formulation and the second formulation with the at least one pump for a first time period such that the first formulation and the second formulation pass from the formulation cartridge, through the at least one pump, and exit the nozzle assembly,
• wherein the controller comprises logic configured to operate the at least one pump such that the first formulation and the second formulation exit the nozzle assembly at an operating flow rate and a priming flow rate, wherein the priming flow rate is greater than the operating flow rate, wherein the priming sequence comprises pumping the first formulation and the second formulation at the priming flow rate.

• wherein the handle houses a cartridge authentication interface, and wherein the controller comprises logic which, when executed by the processor, authenticates the formulation cartridge inserted into the handle by reading an encryption chip disposed on the formulation cartridge with the cartridge authentication interface, wherein the priming sequence can only be initiated following successful authentication of the formulation cartridge.
