Patent ID: 8439879

Claim:
A device for supporting a cannula during administering of a fluid through the skin, the device comprising: (a) a base comprising a holder for retaining a cannula in a cannula position suitable for administering a fluid through the skin, said base having a skin contact surface for adhesive attachment to the skin; (b) a mechanical sensing element retained in a first position relative to said base by contact with the skin while said skin contact surface is attached to the skin, said mechanical sensing element being displaceable to a second position when said skin contact surface is detached from the skin; and (c) an occluding element mechanically biased to move relative to said base from a non-occluding position to an occluding position, said occluding position being such that, when a cannula is retained in said cannula position, said occluding element acts on the cannula to at least partially occlude flow through the cannula, said occluding element being mechanically linked to said mechanical sensing element so as to be selectively retained in said non-occluding position while said mechanical sensing element is in said first position.
