Abstract

The present invention provides a reservoir compartment adapter for use with a fluid delivery device. The adapter includes a first end adapted for coupling with a fluid delivery device, a second end adapted for coupling with a connector, and a structure between the first end and the second end including an interior space for receiving the reservoir, wherein an extended reservoir compartment for accommodating the reservoir is adapted to be formed when the first end is coupled to the fluid delivery device, and the reservoir is adapted to be secured in the extended reservoir compartment when the connector is coupled to the second end. The adapter allows a user of a delivery device accommodating reservoirs of a certain size to manage periods where increased medication dosage is needed without the burden of carrying a larger delivery device for accommodating reservoirs filled with the increased dosage.

Claims

1. A reservoir compartment adapter for use with a reservoir containing fluid, a fluid delivery device for delivering the fluid from the reservoir into a body, the fluid delivery device having a reservoir compartment, the reservoir compartment having a first length and including a first interior space for receiving the reservoir, and a connector for coupling with the reservoir, the reservoir compartment adapter having a second length and further comprising:

a first end and a second end, the reservoir compartment adapter including a second interior space for receiving the reservoir, the first end defined to couple with an outlet end of the fluid delivery device, the second end defined to couple with the connector, wherein the second end extends past the outlet end when the first end is removably coupled with the outlet end, and wherein the reservoir compartment adapter is between the connector and the outlet end when the first end is removably coupled with the outlet end and the second end is removably coupled with the connector,

wherein an extended reservoir compartment having a third length is formed by adding the second length to the first length when the first end of the reservoir compartment adapter is removably coupled to the outlet end of the fluid delivery device, wherein the third length is equal to or longer than the reservoir, the extended reservoir compartment being further defined by the first interior space and the second interior space to secure the reservoir entirely within the extended reservoir compartment when the connector is coupled to the second end, the reservoir being removable from the extended reservoir compartment without uncoupling the first end from the fluid delivery device.

2. The adapter of claim 1, wherein the first end comprises a first thread member for mating with a second thread member formed on the fluid delivery device.

3. The adapter of claim 2, wherein the first end comprises male threads formed on an exterior diameter of the first end for mating with female threads formed on an interior diameter of the reservoir compartment.

4. The adapter of claim 1, wherein the second end comprises a first thread member for mating with a second thread member formed on the connector.

5. The adapter of claim 4, wherein the second end comprises female threads formed on an interior diameter of the second end for mating with male threads formed on an exterior diameter of the connector.

6. The adapter of claim 1, wherein the first end comprises one or more detents that extend radially from the exterior of the first end and are adapted to engage into detent openings in the fluid delivery device.

7. The adapter of claim 1, wherein the first end comprises a shoulder seated against a housing or existing seal of the fluid delivery device to form a watertight seal.

8. The adapter of claim 1, wherein the connector is an interface between the reservoir and a conduit for delivering the fluid from the reservoir into the body.

9. The adapter of claim 1, wherein the reservoir is sized to hold approximately 3.0 mL of fluid when the adapter is coupled to the fluid delivery device.

10. The adapter of claim 1, wherein the reservoir is longer than the first length and extends past the outlet end.

11. The adapter of claim 1, wherein a diameter of the reservoir can pass within an interior diameter of the adapter.

12. A fluid delivery system for delivering fluid into a body, the system comprising:

a reservoir that contains the fluid;

a fluid delivery device that delivers the fluid from the reservoir into the body, the fluid delivery device including a reservoir compartment having a first length and including a first interior space for receiving the reservoir;

a connector to be coupled to the reservoir; and

a reservoir compartment adapter having a second length and including a second interior space for receiving the reservoir, the reservoir compartment adapter having a first end defined to couple with an outlet end of the fluid delivery device and a second end defined to couple with the connector, wherein the second end extends past the outlet end when the first end is removably coupled with the outlet end, and wherein the reservoir compartment adapter is between the connector and the outlet end when the first end is removably coupled with the outlet end and the second end is removably coupled with the connector,

wherein an extended reservoir compartment having a third length is formed by adding the second length to the first length when the first end of the reservoir compartment adapter is removably coupled to the outlet end of the fluid delivery device, wherein the third length is equal to or longer than the reservoir, the extended reservoir compartment being further defined by the first interior space and the second interior space to entirely contain the reservoir when the connector is coupled to the second end of the reservoir compartment adapter, the reservoir being removable from the extended reservoir compartment without uncoupling the first end of the reservoir compartment adapter from the fluid delivery device.

13. The system of claim 12, wherein the first end comprises a first thread member for mating with a second thread member formed on the fluid delivery device.

14. The system of claim 13, wherein the first end comprises male threads formed on an exterior diameter of the first end for mating with female threads formed on an interior diameter of the reservoir compartment.

15. The system of claim 12, wherein the second end comprises a first thread member for mating with a second thread member formed on the connector.

16. The system of claim 15, wherein the second end comprises female threads formed on an interior diameter of the second end for mating with male threads formed on an exterior diameter of the connector.

17. The system of claim 12, wherein the first end of the reservoir compartment adapter comprises one or more detents that extend radially from the exterior of the first end and are adapted to engage into detent openings in the fluid delivery device.

18. The adapter of claim 12, wherein the first end of the reservoir compartment adapter comprises a shoulder seated against a housing or existing seal of the fluid delivery device to form a watertight seal.

19. The system of claim 12, wherein the connector is an interface between the reservoir and a conduit for delivering the fluid from the reservoir into the body.

20. The system of claim 12, wherein the reservoir is sized to hold approximately 3.0 mL of fluid when the reservoir compartment adapter is coupled to the fluid delivery device.

21. The system of claim 12, further comprising a detection system for detecting that the reservoir compartment adapter is coupled to the fluid delivery device.

22. The system of claim 21, wherein the detection system includes at least one of:

a magnetic sensor;

an optical sensor;

a mechanical switch; and

a color sensor.

23. The system of claim 21, wherein the reservoir compartment adapter includes at least a portion of the detection system.
