Gateway Device
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.
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.
23 . (canceled)
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.
