Abstract: An infusion set for use with a fluid infusion device is provided. The infusion set can include a mount including a projection having a bore. The projection can be surrounded at least partially by a recess defined through a surface of the mount, and the mount can include at least one rib that spans the recess. The infusion set can include a fluid outlet coupled to at least a portion of the bore of the projection and a coupling device to couple the infusion set to a user. The coupling device can be coupled to the surface and the at least one rib of the mount.

Abstract: An injection apparatus for making an injection at a predetermined depth in skin comprises: a first skin positioning member, a second skin positioning member, wherein the first and second skin positioning members lie or are moveable to lie in an injection arrangement; an injection needle; and an injection needle movement guide to guide the injection needle for movement from a parking position above the skin, through the lower surface of the second skin positioning member to slide beneath the first skin positioning member to an injection position. A further injection apparatus comprises: an injection needle; a plunger within the injection needle; and a retractor to retract the injection needle such that material to be injected is expelled from the injection needle by the plunger.

Abstract: An optical glucose sensor may include an optical fiber and a glucose-permeable membrane having a hollow interior and being coupled to the optical fiber's distal end. The membrane's hollow interior provides a compartment to house a competitive glucose binding affinity assay. The assay may include a glucose analog that may be labeled with a dye, and a glucose receptor that may be labeled with a fluorophore. The optical fiber may include a compound parabolic concentrator tip, and the compartment may additionally house a reflector disposed so as to face the optical fiber's tip. A fluorophore-labeled assay may be interrogated by an optical interrogating system including a light source and a filter substrate having one or more coatings to effect, e.g., an excitation filter and/or an emission filter. The interrogating system may be manufactured as a stacked planar integrated optical system and diced into smaller units.

Abstract: An injection apparatus (1) for making an injection at a predetermined depth in skin comprises: a first skin positioning member (4, 26); a second skin positioning member (3, 54), wherein the first and second skin positioning members lie or are moveable to lie in an injection arrangement; an injection needle (50); and means guiding the injection needle for movement from a parking position above the skin, through the lower surface of the second skin positioning member to slide beneath the first skin positioning member to an injection position. A further injection apparatus comprises: an injection needle; a plunger (44) within the injection needle; and means for retracting the injection needle such that material to be injected is expelled from the injection needle by the plunger.

Abstract: An injection apparatus is described for making an injection at a predetermined depth in skin, including: a skin positioning member for positioning on a patch of skin within an area of skin such that at least a part of the patch of skin may be held elevated above or depressed below the area of skin, an injection needle, and a guidance mechanism for guiding the injection needle to slide beneath the skin positioning member to an injection position in which the distal end of the needle lies at a predetermined distance below the skin positioning member. An injection apparatus is also described including a detachable marker unit and a securing element for securing the marker unit at an injection site prior to the making of an injection to mark the position of the injection site.

Abstract: A needle assembly comprises an injection needle and a needle hub, mountable on a syringe, for securing the injection needle. The needle has an injection part extending axially from the hub and terminating in a skin piercing obliquely cut end. The length of the injection part is between 4 and 6 mm, thereby facilitating a proper subcutaneous injection. Also, preferably either (a) the outer diameter of the needle is smaller than 0.320 mm and the bore diameter is larger than 0.165 mm, or (b) the outer diameter is smaller than 0.298 mm and the bore diameter is larger than 0.133 mm. Also, preferably the hub includes an axially extending protrusion, from which the injection part extends, to facilitate insertion of the injection part into the skin of a user at an oblique angle.

Abstract: A needle unit comprises a needle mounted in a hub having a sleeve made from a deformable material and surrounding an end of the needle at a radial distance from that needle. The sleeve is designed to be snap-locked onto a connecting piece at the outlet end of a syringe by protrusions on the inner wall of the sleeve engaging a circumferential recess in the outer wall of the connecting piece. It is also designed such that the locking engagement between the protrusions of this sleeve and the recess of the connecting piece is released when certain zones of the outer sleeve wall are pressed inwardly. A magazine for storing the needle unit comprises a compartment which can receive the needle unit in a plurality of rotational positions.

Abstract: In a displacement system for controlled infusion of a liquid from a cartridge comprising a tubular vessel (1), which is at a rear end closed by a piston (3) which may be forced by a piston rod (8) moving into the vessel (1) in the axial direction thereof to press out the liquid through an outlet (2) arranged at a front end of the vessel (1), the piston rod (8) is provided as a flexible incompressible construction which is by a piston rod guide (9) behind the rear end of the cartridge deflected away from the axis of this cartridge, preferably 180.degree.. The piston rod guide (9) has a guiding track comprising a curved part and linear parts at each end of the curved part ensuring that the piston rod is guided along a length (a) in the direction of the axis of the cartridge which length (a) is longer than the distance (b) between the two axes of the piston rod parts projecting from the piston rod guide.
