Abstract

A device for delivering medicament into skin of a patient, the device having a housing, which includes a reservoir for housing the medicament, a first internal region that is sealed from fluid ingress and includes one or more components, and a second internal region that is not sealed from fluid ingress and includes one or more components. The housing also has a barrier that separates the first internal region and the second internal region, a delivery cannula that delivers the medicament into the skin of the patient, and a base including a bottom surface for orienting toward the skin of the patient. The bottom surface of the base has one or more fluid channels disposed therein and at least one of the fluid channels is in fluid communication with the delivery cannula.

Claims

1. A device for delivering medicament into skin of a patient, the device comprising:

a housing comprising;

a reservoir for housing the medicament;

a first internal region that is sealed from fluid ingress and includes one or more components;

a second internal region that is not sealed from fluid ingress and includes one or more components;

a barrier that separates the first internal region and the second internal region;

a base including a bottom surface for orienting toward the skin of the patient, the bottom surface of the base having one or more fluid channels disposed therein; and

a delivery cannula that delivers the medicament into the skin of the patient;

wherein at least one of the fluid channels is in fluid communication with the delivery cannula.

2. The device according to claim 1, wherein:

the components in the first internal region include one or more of a pump, a force sensing resistor, and electronics; and

the components in the second internal region include the delivery cannula.

3. The device according to claim 1, wherein a size of the fluid channel does not limit fluid flow.

4. The device according to claim 1, wherein

the fluid channel is recessed from the bottom surface of the base;

and

the medicament passes through the base from the first internal region to the second internal region.

5. The device according to claim 1, wherein the fluid channel is in fluid communication with the delivery cannula while bypassing the barrier.

6. The device according to claim 1, further comprising:

a plate including one or more fluid channels; and

the fluid channel of the plate being encapsulated by a fluid channel cover.

7. The device according to claim 6, wherein the fluid channels in the plate are disposed at different elevations with respect to the base.

8. The device according to claim 6, wherein the plate is disposed entirely in the first internal region.

9. The device according to claim 1, further comprising a fluid channel cover that encapsulates at least one of the fluid channels.

10. The device according to claim 9, wherein the cover comprises foil attached to the base.

11. The device according to claim 9, wherein the cover seals the bottom surface of the base.

12. The device according to claim 9, wherein the cover encapsulates each of the fluid channels.

13. The device according to claim 9, wherein a separate cover encapsulates each of the fluid channels.

14. The device according to claim 1, wherein:

one of the fluid channels transfers medicament to an input of a component of the device component; and

one of the fluid channels transfers medicament from an outlet of the component of the device component to the delivery cannula.

15. The device according to claim 14, wherein the component of the device component comprises a force sensing resistor.

16. A medicament delivery device comprising:

a housing having an interior, the housing having a fluid channel disposed therein;

wherein the fluid channel passes from a first position in the interior, to a second position outside the housing, and to a third position in the interior.

17. The medicament delivery device according to claim 16, wherein the fluid channel is recessed into the housing.

18. A medicament delivery method comprising:

disposing medicament in an interior of a housing; and

transporting the medicament in a fluid channel traveling from the interior of the housing to outside of the housing, and back into the interior of the housing.

19. The method according to claim 18, wherein the fluid channel is recessed into the housing.

20. A medicament delivery device comprising:

a housing having an interior, the housing including;

a reservoir for housing medicament;

a fill port in fluid communication with the reservoir;

a delivery mechanism that delivers the medicament into skin of a patient;

a pump that controls flow of the medicament to the delivery mechanism; and

a base having first and second fluid channels disposed therein;

wherein the pump is in fluid communication with the delivery mechanism via the first fluid channel; and

one of the fluid channels is disposed, at least in part, outside the interior of the housing.

21. The medicament delivery device according to claim 20, wherein the fill port is in fluid communication with the pump via the second fluid channel.
