Skin testing device

A skin testing applicator comprising:

• a plate portion;
• a hollow rigid handle portion attached to the plate portion on one side open at a top end thereof and adapted for manually grasping the device;
• and
• a hollow cannula element mounted on said plate and extending outwardly at least 0.5 mm. from said plate opposite said handle portion for intracutaneous injection, said cannula having a sharp skin-piercing point at its lower extremity and an upper shaft portion extending upwardly through said plate into said hollow handle portion, whereby said applicator may be loaded with a predetermined amount of skin testing substance and distributed into the cannula by capillary action.

An injection unit for intracutaneous allergenic skin test use comprising:

• a two-tier hilt having a small central hilt portion and a large outer hilt portion recessed from said central hilt portion;
• upwardly extending handle means attached to said hilt on one side thereof and adapted for manually grasping the unit;
• downwardly extending skin test prong means for capillary loading of biological test liquid, including reservoir means for holding a predetermined amount of test liquid for intracutaneous deposition and a sharp skin-piercing point extending about 0.5 to 3 mm. from said hilt;
• said prong means being attached adjacent said central hilt portion, and thereby disguising puncture of said point and providing standardized skin penetration.
