Infusion set
First Claim
1. An infusion set comprising an infusion part for insertion into a patient and a connector for connecting the infusion part with a medical device through a tube, the connector being axially displaceable relative to the infusion part,the infusion part comprising:
- an adhesive support;
a base connected to the adhesive support, the base part including a first set of guides and at least two retention devices for releasably locking the connector to the infusion part, said retention devices extending upwardly from an upper surface of the base;
a first cannula extending from said base and being in fluid communication with a cavity, said cavity being adapted to receive a second cannula extending from the connector, wherein said second cannula is in fluid communication with the tube; and
the connector comprising;
a second set of guides adapted to fit with the first set of guides and at least two arms adapted to fit with the retention devices, the arms are movable in a laterally inward direction, in a laterally outward direction and in an upward direction away from the base such that movement of the arms in either the laterally inward direction, the laterally outward direction or the upward direction allows disengagement of the arms from the retention devices.

Abstract
The invention relates to an infusion set for an intermittent or continuous administration of a therapeutical substance, such as insulin. The infusion set comprises an infusion part (OB) for insertion into a patient and a connector (OA) for connecting the infusion part with a medical device through a tube (7), the connector being axially displaceable relative to the infusion part. The infusion part comprises an adhesive support (1), a base part (2) with a first set of guiding means (13) and at least two retention devices (4) for locking the connector to the infusion part, a cannula extending from said base part and being in fluid communication with a cavity which is optionally covered with a membrane, the cavity is further adapted to receive a second cannula extending from the connector, which second cannula is in fluid communication with the tube.

23. An infusion set comprising an infusion part and a connector releasably connectable to the infusion part,
the infusion part comprising: -
a base having a lower surface and an upper surface, the upper surface comprising a first guide and a releasable locking member extending upwardly from the upper surface for releasably connecting the infusion part to the connector; and a first cannula extending outwardly from the base, the connector comprising; a second guide adapted to fit with the first guide; an arm operably connected to the second guide for releasably interlocking with the locking member, the arm is movable in a laterally inward direction, in a laterally outward direction and in an upward direction away from the base such that movement of the arm in either the laterally inward direction, the laterally outward direction or the upward direction allows disengagement of the arm from the releasable locking member; and a second cannula extending outwardly from the connector and adapted for reception at least partially within a cavity formed in the base; wherein the first cannula and the second cannula are fluidly connectable. - View Dependent Claims (24, 25, 26, 27)
