Abstract

An external infusion device that infuses a fluid into an individual'"'"'s body includes a housing, a reservoir, a drive system, a power supply, electrical elements, and a tab. The reservoir contains the fluid, and the drive system forces the fluid from the reservoir. The electrical elements control the power to the drive system to regulate the rate that fluid is forced from the reservoir. The tab mates with the housing, and contains at least one electrical element. The tab is removable, and may be replaced with a different tab. The different tab may change the rate fluid is forced from the reservoir. A tab may be removed from one external infusion device and installed in a different external infusion device. The tab may be limited to use in a predetermined number of external infusion devices and may include a power supply.

Claims

1. An infusion system for infusing a fluid into a body, comprising:

an infusion device having

a first surface having an adhesive layer for attaching the infusion device to the skin, and

a second surface having one or more electrical terminals;

a replaceable fluid containing reservoir;

a needle or cannula in communication with the reservoir and extending through a periphery the first surface of the infusion device; and

a tab that removably mates with the second surface of the infusion device to form and seal a housing when mated with the infusion device, the tab having

a drive system to force the fluid from the reservoir,

an electronics system to control the drive system,

one or more batteries to power the electronics system and the drive system, and

one or more conductive traces;

wherein one or more components included with the tab are reusable, and wherein the one or more conductive traces come in contact with the one or more electrical terminals when the tab mates with the second surface to provide an electrical contact between the infusion device and tab.

2. The infusion system of claim 1, wherein the tab further includes at least one of a communications system, an output device, and an input device.

3. The infusion system of claim 1, wherein the one or more components included with the tab are sensitive to sterilization treatments.

4. The infusion system of claim 1, wherein the reservoir can only be filled once.

5. The infusion system of claim 1, wherein the infusion device or the tab further includes an indicator to indicate at least one of the drive system is powered, fluid delivery is in process, and power supply status.

15. The infusion system of claim 1, wherein the tab has a predetermined usage life that is programmed into the electronics system, and when the predetermined usage life for the tab expires, the electronics system disables the tab from infusing the fluid from the reservoir into the body;

and

wherein the predetermined usage life for the tab is programmed into the electronics system as a predetermined amount of time that the tab is in use.

16. The infusion system of claim 1, wherein the tab has a predetermined usage life that is programmed into the electronics system, and when the predetermined usage life for the tab expires, the electronics system disables the tab from infusing the fluid from the reservoir into the body;

and

wherein the predetermined usage life for the tab is programmed into the electronics system as a predetermined number of times that the reservoir is emptied.

6. An infusion system for infusing a fluid into a body, comprising:

an infusion device having

a first surface having an adhesive layer for attaching the infusion device to the skin, and

a second surface having one or more electrical terminals;

a replaceable fluid containing reservoir;

a needle or cannula in communication with the reservoir and extending through a periphery of the first surface of the infusion device; and

a tab that removably mates with the second surface of the infusion device to form and seal a housing when mated with the infusion device, the tab having

at least a portion of a drive system to force the fluid from the reservoir,

an electronics system to control the drive system,

one or more batteries to power the electronics system and the drive system, and

one or more conductive traces;

wherein one or more components included with the tab are reusable, and wherein the one or more conductive traces come in contact with the one or more electrical terminals when the tab mates with the second surface to provide an electrical contact between the infusion device and tab.

7. The infusion system of claim 6, wherein the tab further includes at least one of a communications system, an output device, and an input device.

8. The infusion system of claim 6, wherein the one or more components included with the tab are sensitive to sterilization treatments.

9. The infusion system of claim 6, wherein the reservoir can only be filled once.

10. The infusion system of claim 6, wherein the infusion device or the tab further includes an indicator to indicate at least one of the drive system is powered, fluid delivery is in process, and power supply status.

17. The infusion system of claim 6, wherein the tab has a predetermined usage life that is programmed into the electronics system, and when the predetermined usage life for the tab expires, the electronics system disables the tab from infusing the fluid from the reservoir into the body;

and

wherein the predetermined usage life for the tab is programmed into the electronics system as a predetermined amount of time that the tab is in use.

18. The infusion system of claim 6, wherein the tab has a predetermined usage life that is programmed into the electronics system, and when the predetermined usage life for the tab expires, the electronics system disables the tab from infusing the fluid from the reservoir into the body;

and

wherein the predetermined usage life for the tab is programmed into the electronics system as a predetermined number of times that the reservoir is emptied.

11. An infusion system for infusing a fluid into a body, comprising:

an infusion device having

a first surface having an adhesive layer for attaching the infusion device to the skin, and

a second surface having one or more electrical terminals;

a replaceable fluid containing reservoir, the reservoir can only be filled once;

a needle or cannula in communication with the reservoir and extending through a periphery of the first surface of the infusion device; and

a tab that removably mates with the second surface of the infusion device to form and seal a housing when mated with the infusion device, the tab having

at least a portion of a drive system to force the fluid from the reservoir,

an electronics system to control the drive system,

one or more batteries to power the electronics system and the drive system, and

one or more conductive traces;

wherein one or more components included with the tab are reusable, and wherein the one or more conductive traces come in contact with the one or more electrical terminals when the tab mates with the second surface to provide an electrical contact between the infusion device and tab.

12. The infusion system of claim 11, wherein the tab further includes at least one of a communications system, an output device, and an input device.

13. The infusion system of claim 11, wherein the one or more components included with the tab are sensitive to sterilization treatments.

14. The infusion system of claim 11, wherein the infusion device or the tab further includes an indicator to indicate at least one of the drive system is powered, fluid delivery is in process, and power supply status.

19. The infusion system of claim 11, wherein the tab has a predetermined usage life that is programmed into the electronics system, and when the predetermined usage life for the tab expires, the electronics system disables the tab from infusing the fluid from the reservoir into the body;

and

wherein the predetermined usage life for the tab is programmed into the electronics system as a predetermined amount of time that the tab is in use.
