Japanese Patent JP4613158
Kind Code:
B2
Abstract:
A medication delivery device, particularly an intradermal delivery device, having a needle cannula, with a sharpened distal end having a forward tip, and a limiter disposed about the needle cannula. The limiter has a distal end defining a skin engaging surface which is disposed transversely to, and at least partially about, the needle cannula. The skin engaging surface is generally non-flat with generally coplanar portions, and a recess being defined in the skin engaging surface which defines a void in or adjacent to the coplanar portions into which portions of a patient's skin can be deformed into when the skin engaging surface is pressed against the patient's skin. The forward tip of the needle cannula is spaced apart from a plane defined by the coplanar portions a distance ranging from about 0.5 mm to 3.0 mm such that the skin engaging surface limits penetration of the forward tip of the needle cannula to the dermis layer of the patient's skin.
