Abstract

Formulation delivery systems, formulation delivery devices, and formulation cartridges for the same are provided. Formulation delivery systems include a reusable handle, a formulation dispensing assembly, and a controller. The formulation dispensing assembly includes a reciprocating nozzle assembly and a pump. The reciprocating nozzle assembly is fluidically-coupleable to the formulation cartridge or the cleaning cartridge received within the reusable handle. Formulation delivery devices include a reusable handle configured to receive a formulation cartridge therein, and a formulation dispensing assembly disposed in the reusable handle. The formulation dispensing assembly includes fluid conduits, a pump fluidically connected to the fluid conduits, a reciprocating nozzle assembly, and a controller. Formulation cartridges include a reusable cartridge body, a valve frame, and a disposable refill packet reversibly-coupleable to the reusable cartridge body. The disposable refill packet includes a formulation packet and a body portion configured for insertion into the reusable cartridge body.

First claim

What is claimed is:

1. A formulation delivery device, comprising:
a reusable handle configured to receive a formulation cartridge therein; and
a formulation dispensing assembly disposed in the reusable handle, the formulation dispensing assembly having:
at least a first fluid conduit and a second fluid conduit that are respectively configured to fluidically connect with a first formulation packet and a second formulation packet of the formulation cartridge;
a pump fluidically connected to the first fluid conduit and second fluid conduit;
a reciprocating nozzle assembly fluidically connected to the first fluid conduit, the second fluid conduit, and the pump; and
a controller disposed in the reusable handle, wherein the controller comprises logic, which when executed, causes the formulation delivery device to:
authenticate the formulation cartridge; and
execute, based upon authenticating the formulation cartridge, a formulation routine that manages:
a reciprocating frequency of the reciprocating nozzle assembly, and
a dispensing rate of a formulation from the formulation cartridge through the formulation dispensing assembly.

2. The formulation delivery device of claim 1 , further comprising the formulation cartridge and the formulation.

3. The formulation delivery device of claim 1 , wherein the controller comprises logic, which when executed, causes the formulation delivery device to:
authenticate a cleaning cartridge inserted into the reusable handle; and
execute, based upon authenticating the cleaning cartridge, a cleaning routine that dispenses a cleaning liquid from the cleaning cartridge through the formulation dispensing assembly.

4. The formulation delivery device of claim 3 , further comprising the cleaning cartridge, wherein the cleaning cartridge comprises a cleaning liquid reservoir fluidically connected to a plurality of cleaning liquid output nozzles.

5. The formulation delivery device of claim 3 , wherein the cleaning routine operates the pump at a higher flow rate than the formulation routine.

6. The formulation delivery device of claim 1 , wherein the formulation dispensing assembly comprises a turbulent mixing chamber in fluid connection with the first fluid conduit and the second fluid conduit, the turbulent mixing chamber comprising a helical mixer.

7. The formulation delivery device of claim 6 , wherein the formulation dispensing assembly comprises a second helical mixer fluidically connected in series with the helical mixer.

8. The formulation delivery device of claim 6 , wherein the turbulent mixing chamber is disposed along the first fluid conduit and the second fluid conduit between a pump and the reciprocating nozzle assembly.

9. The formulation delivery device of claim 8 , wherein the first fluid conduit and second fluid conduit are fluidically separated until the turbulent mixing chamber.

10. The formulation delivery device of claim 8 , wherein the first fluid conduit and the second fluid conduit remain fluidically separate through the pump.

11. The formulation delivery device of claim 6 , wherein the helical mixer has an outside diameter between 2.00 mm and 5.00 mm.

12. The formulation delivery device of claim 11 , wherein the helical mixer has a total length between 20.0 mm and 40.0 mm.

13. The formulation delivery device of claim 12 , wherein the helical mixer helical mixer has a length-to-diameter pitch between 0.75 and 1.25, wherein the length-to-diameter pitch is defined as:
length-to-diameter pitch=total length/[outside diameter*number of mixing elements].

14. The formulation delivery device of claim 6 , wherein the pump is a peristaltic pump.

15. The formulation delivery device of claim 14 , wherein each nozzle of the reciprocating nozzle assembly has a tapered formulation channel therethrough.

16. The formulation delivery device of claim 1 , wherein the controller comprises logic, which when executed, causes the formulation delivery device to determine a dispensed time of the formulation from the formulation cartridge.

17. The formulation delivery device of claim 16 , wherein the formulation delivery device comprises a visual indicator disposed on the reusable handle that signals a remaining formulation quantity based upon the dispensed time.

18. The formulation delivery device of claim 1 , further comprising a pull through adaptor that attaches to the reusable handle over the reciprocating nozzle assembly.

19. The formulation delivery device of claim 2 , wherein the formulation is a mixture of a first formulation and a second formulation at a ratio of 0.8:1.0-1.2:1.0.

20. The formulation delivery device of claim 1 , further comprising a cartridge authentication interface disposed in the reusable handle that reads an encryption chip of the formulation cartridge after insertion of the formulation cartridge into the reusable handle.

21. The formulation delivery device of claim 20 , wherein the formulation delivery device comprises logic, which when executed by the controller, causes the formulation delivery device to determine, from the encryption chip, at least one of a formulation identification, a beginning formulation quantity, a formulation expiration date, or a formulation production date.

22. The formulation delivery device of claim 1 , wherein the formulation dispensing assembly dispenses the formulation at a flow rate of 20-40 mL/min.

23. The formulation delivery device of claim 1 , wherein a reciprocating amplitude of the reciprocating nozzle assembly is 8.0 mm-11.0 mm.

24. The formulation delivery device of claim 1 , wherein the reciprocating frequency of the reciprocating nozzle assembly is 6.0 Hz-8.0 Hz.

25. The formulation delivery device of claim 1 , wherein each the first fluid conduit and the second fluid conduit comprise a formulation inlet at an upstream end thereof, each formulation inlet being formed as a rearward-extending protrusion that is configured to project into the formulation cartridge.
