Intradermal pen adapter
First Claim
1. An intradermal injection adapter for making an intradermal injection, the adapter comprising:
- a body having a longitudinal axis;
a central portion located distally relative to the body along the longitudinal axis, the central portion having a cannula channel therethrough extending parallel to the longitudinal axis;
a cannula within the cannula channel and permanently fixed to the central portion, the cannula having a sharpened tip for injection into a patient and a sharpened opposite proximal end for injection into a pen injector; and
a distal protrusion having a first skin contacting surface extending parallel to the longitudinal axis, the first skin contacting surface being spaced from the cannula such that a distal portion of the cannula extends parallel to the first skin contacting surface.

Abstract
An intradermal injection adapter includes a body having a longitudinal axis and a central portion located distally relative to the body along the longitudinal axis. The central portion has a cannula channel therethrough extending generally parallel to the longitudinal axis. A cannula within the cannula channel has a sharpened tip for injection into a patient and a sharpened opposite proximal end for injection into a pen injector. A distal protrusion has a first skin contacting surface extending generally parallel to the longitudinal axis. The first skin contacting surface is spaced from the cannula such that a distal portion of the cannula extends generally parallel to the first skin contacting surface.

3. An intradermal injection assembly for injecting a medicament into a dermal skin layer, the assembly comprising:
-
a pen injector including a barrel and a plunger, the barrel having a cylindrical configuration and a hollow internal cavity adapted to receive the medicament therein; and an adapter having a body, a central portion with a cannula channel permanently fixedly attached to a cannula, a distal protrusion with a distal nose, a proximal end portion and a longitudinal axis extending between the proximal end portion and the distal nose, the cannula having a sharpened tip for injection into a patient and a sharpened opposite proximal end for injection into the pen injector, the distal protrusion includes a first skin contacting surface positioned parallel to the longitudinal axis, a distal portion of the cannula spaced from the first skin contacting surface at a cannula gap distance in the assembled configuration. - View Dependent Claims (4, 5, 6)
