Subcutaneous injection set
First Claim
1. A subcutaneous injection set comprising:
- a base element having a hub with a top, a bottom and an outer surface, said outer surface extending between said top and said bottom, a cavity within said hub and an entry lumen extending from said outer surface to said cavity;
a top element mounted on said base element to be rotatable about an axis through said hub and having an inner flange with an outer surface and an inner surface, said inner surface of said flange mating with said outer surface of said hub in the area around the entry lumen, said flange having an aperture extending between said inner and outer surface of said flange, which aperture in one position of the top element in relation to the base element is aligned with said entry lumen of said hub and said flange in a further rotated position of the top element in relation to the base element covers said entry lumen in said hub;
a cannula mounted in and extending from said hub of said base element so as to protrude from said bottom, said cannula having a lumen therethrough, said lumen communicating with the entry lumen of said hub to said cavity;
connector means for administering a fluid to said aperture in said flange of said top element.

Abstract
A subcutaneous injection set for administering a medication or a therapeutic fluid to a patient is disclosed. The injection set comprises a base element having a hub with a top and a bottom and an outer surface extending between said top and said bottom, a cavity within said hub and an entry lumen extending from said outer surface to said cavity. A top element is mounted on said base element to be rotatable about an axis through said hub and having a flange with an inner surface mating with said outer surface of said hub in the area around the entry lumen, said flange having an aperture extending between said inner surface and an outer surface, which aperture in one position of the top element in relation to the base element is aligned with said entry lumen of said hub and said flange in a further rotated position of the top element in relation to the base element covers said entry lumen in said hub. A cannula is mounted in and extending from said hub of said base element, said cannula having a lumen therethrough, said lumen communicating with the entry lumen of the central hub through said cavity. Connector means for administering a fluid to said opening in said flange of said top element are provided.
