Abstract

A dispenser for medicaments comprises a first metering pump for insulin and a second metering pump for glucose or glucagon. A controller for both pumps is programmed to maintain a basal supply of insulin, and is responsive to a signal from a separate glucometer to dispense additional insulin or glucose or glucagon as appropriate.

Claims

1. A dispenser for medicaments, comprising:

a first metering pump for insulin;

a second metering pump for glucose or glucagon; and

a controller for both pumps, wherein the controller is programmed to maintain a basal supply of insulin, and is responsive to a signal from a separate glucometer to dispense additional insulin or additional glucose or glucagon as appropriate.

2. A dispenser according to claim 1, further comprising a wireless receiver for receiving the signal from the separate glucometer.

3. A dispenser according to claim 1, further comprising a pair of flexible tubes arranged to be connected at one end to a respective one of the first and second metering pumps and at the other end to a connector for a cannula arranged to be inserted through the skin of a patient.

4. A dispenser according to claim 3, wherein both of the pair of flexible tubes are connected to a single connector for a single cannula.

5. A dispenser according to claim 3, wherein the flexible tubes are joined together over a major portion of their length.

6. A dispenser according to claim 1, wherein said first and second metering pumps are arranged to receive reservoirs of medicament of different configurations.

7. A dispenser according to claim 6 in combination with a first reservoir for insulin and a second reservoir for glucose or glucagon, wherein said first metering pump receives said first reservoir but not said second reservoir, and said second metering pump receives said second reservoir but not said first reservoir.

8. A dispenser according to claim 1 in combination with a first reservoir containing insulin and a second reservoir containing glucose or glucagon, wherein said first metering pump is arranged to dispense the contents of the first reservoir, and the second metering pump is arranged to dispense the contents of the second reservoir.

9. A dispenser according to claim 8, wherein one of said first and second reservoirs contains both insulin and glucose or glucagon, wherein the controller is arranged to dispense basal insulin and basal glucose or glucagon by dispensing fluid from the said one reservoir.

10. A dispenser according to claim 1, further comprising a third metering pump for a mixture of insulin and glucose or glucagon;

wherein the controller is programmed to maintain a basal supply of insulin and glucose or glucagon by the third metering pump, and is responsive to a signal from a separate glucometer to dispense additional insulin by the first metering pump or additional glucose or glucagon by the second metering pump as appropriate.

11. A refill for a medicament dispenser, comprising:

a first cartridge of insulin;

a second cartridge of glucose or glucagon;

at least one connector for connection to a subcutaneous infusion cannula; and

flexible tubes connecting both cartridges to the at least one connector.

12. A refill according to claim 11, wherein the first and second cartridges are of different configurations such that each cartridge can be non-interchangeably inserted into a respective one of first and second metering pumps with correspondingly different configurations.

13. A refill according to claim 11, comprising a said connector to which both cartridges are connected by the flexible tubes.

14. A refill according to claim 11, comprising two said connectors, and wherein the cartridge of insulin is connected to one of the connectors by one of the flexible tubes and the cartridge of glucose or glucagon is connected to the other connector by another of the flexible tubes.

15. A refill according to claim 11, wherein the first and second cartridges are formed in a single unit.

16. A refill for a medicament dispenser, comprising:

a first cartridge containing a medicament;

a connector for connection to a subcutaneous infusion cannula;

a flexible tube connecting the cartridge to the connector; and

a removable seal closing the flexible tube at the connector.

17. A refill according to claim 16, further comprising a second cartridge containing a second medicament and a second flexible tube connecting the second cartridge to the connector, and wherein the removable seal closes both flexible tubes at the connector.

18. A refill according to claim 16, wherein the first and second cartridges are of different configurations such that each cartridge can be non-interchangeably inserted into respective first and second metering pumps with correspondingly different configurations.

19. A refill according to claim 16, wherein one of the first and second cartridges contains insulin and the other of the first and second cartridges contains glucose or glucagons.

20. A refill according to claim 16, further comprising a second cartridge containing a second medicament, a second connector for connection to a second subcutaneous infusion cannula, a second flexible tube connecting the cartridge to the connector, and a second removable seal closing the second flexible tube at the second connector.

21. A refill according to claim 20, wherein the first and second cartridges are of different configurations such that each cartridge can be non-interchangeably inserted into respective first and second metering pumps with correspondingly different configurations.

22. A refill according to claim 20, wherein one of the first and second cartridges contains insulin and the other of the first and second cartridges contains glucose or glucagons.
