Abstract:
1. An injectable substance delivery device comprising: at least one needle having a length sufficient to penetrate a skin surface of a patient to an intradermal depth for infusing a substance; a limiter for controlling a needle insertion depth, wherein said limiter controls a maximum insertion depth of said needle into said skin surface without restricting complete insertion of said needle; a spring-loaded depressor for momentarily pushing against said limiter; and a flexible needle holder engaged to a spring member wherein said spring member is cantilevered and engaged to said limiter, further comprising an adhesive for securing said device to said skin surface, wherein said flexible needle holder is secured at a first distance from said limiter for preventing distortion, compression, or thinning of tissue in a vicinity of a needle insertion site such that said needle length and said limiter determine the depth at which said infusion is delivered.
