Abstract

A gateway device for the delivery of a drug, said device comprising a cannula (40) for delivery of said drug, a housing (10) having a base (20) adapted for being placed against the skin of a patient, and a receiving area (30) for receiving a coupling portion (2) of a drug supply device (4) for supplying said drug to said gateway device, said receiving area (30) including a hollow tubular coupling (50) having a free end (52) and being for engaging said coupling portion, said hollow tubular coupling (50) being arranged for delivery of said drug to said patient via said cannula (40). The cannula (40) is secured to said housing (10) to allow said cannula (40) to project from said housing (10), wherein a hollow tubular member with a first end portion and a second end portion defines said cannula and said tubular coupling.

Claims

1. A gateway device for the delivery of a drug, said device comprising:

a housing having

a base adapted for being placed against the skin of a patient;

a hollow tubular member having a first end portion defining a cannula and a second end portion defining a tubular coupling, said cannula secured to said housing to allow said cannula to project from said housing for delivery of said drug; and

a receiving area for receiving a coupling portion of a drug supply device for supplying said drug to said gateway device,

said receiving area including the hollow tubular coupling having a free end configured for engaging said coupling portion,

said hollow tubular coupling being arranged for delivery of said drug to said patient via said cannula.

2. The gateway according to claim 1, wherein said free end of said tubular coupling is adapted for penetrating a septum of said coupling portion.

3. The gateway according to claim 1, wherein said cannula is more flexible than said tubular coupling.

4. The gateway according to claim 1, wherein said cannula comprises a plastics material and said tubular coupling comprises a metal.

5. The gateway according to claim 1, wherein said cannula and said tubular coupling comprise the same material.

6. The gateway according to claim 1, wherein said cannula and said hollow tubular coupling together define a non-leaking flow path for said drug.

7. The gateway according to claim 1, wherein said hollow tubular member is a needle.

8. The gateway according to claim 1, wherein said hollow tubular member is substantially straight.

9. The gateway according to claim 1, wherein said hollow tubular member comprises a bent configuration.

10. The gateway according to claim 1, wherein said tubular coupling extends perpendicularly to said base.

11. The gateway according to claim 1, wherein said tubular coupling extends at an angle to said base.

12. The gateway according to claim 1, wherein said housing includes a releasable cover for covering said tubular coupling.

13. The gateway according to claim 12, wherein said cover surrounds said receiving area.

14. The gateway according to claim 12, wherein said cover is secured to said receiving area by a screw-thread or by snap engagement.

15. The gateway according to claim 12, wherein said cover is hinged to said receiving area.

16. The gateway according to claim 12, wherein said receiving area includes a wall structure surrounding said tubular coupling.

17. The gateway device according to claim 16, wherein said cover being is secured to said wall structure.

18. The gateway device according to claim 16, wherein an imaginary extension of said wall structure below said base surrounds said cannula.

19. The gateway according to claim 1, wherein said receiving area includes a recess.

20. The gateway according to claim 1, wherein said tubular coupling does not project outwardly beyond said receiving area.

21. The gateway according to claim 1, said receiving area being integrally formed with said base, such as by molding.

22. The gateway according to claim 1, wherein said base includes an adhesive layer for securing said base to said patient, said device including releasable protection on said adhesive layer.

24. The gateway according to claim 1, wherein said hollow tubular member comprises a one-piece member.

25. A system comprising the gateway device of claim 1, and a drug supply device with a coupling portion for supplying said drug to said gateway device, said coupling portion including a septum adapted to be penetrated by said hollow tubular coupling.
