Intradermal injection device

An intradermal injection device comprising:

• a unitary body having a open distal end and a proximal end having a first surface portion and a protrusion extending therefrom, a reservoir defined between said distal and proximal ends for accommodating a drug substance, and a channel defined at said proximal end of said unitary body and extending through, and distally from, said proximal end;
• and,
• a needle cannula having a sharpened proximal end and a distal end, said needle cannula being secured in said channel with said distal end being in communication with said reservoir and said proximal end of said needle cannula extending from said protrusion a distance in the range of about 0.5 mm to 3.0 mm such that said protrusion limits penetration of said proximal end of said needle cannula to the dennis layer of the skin of a patient.

A holder for a medicament comprising a unitary body comprising a generally tubular barrel having an open distal end and a proximal end, a reservoir for accommodating a medicament for intradermal delivery being defined between said distal and proximal ends of said generally tubular barrel, a neck portion adjacent said proximal end of said generally tubular barrel, a limiter adjacent a proximal end of said neck portion having a skin engaging surface defined thereon, and a channel defined at said proximal end of said unitary body and extending through, and distally from, said skin engaging surface to said reservoir, said skin engaging surface limiting delivery of the medicament to the dermis layer of a patient's skin.
