1. A catheter attaching device, comprising:

  • a body formed as a substantially inverted cone truncated near the vertex and having a central longitudinal bore;

    a head having a central bore, said head being attached to one end of said body such that said central longitudinal bore and said central bore coincide to create an interior chamber;

    an annular skin cup having a longitudinal bore coincidental with said interior chamber, and having at least two opposed faces, one of said faces being concave, said annular skin cup being integrally positioned between said head and said body, said;

    means for initially puncturing skin, said puncturing means being slidably, rotatably and removably engaged within said interior chamber;

    and securing means for securing said body to a puncture site created by said puncturing means, said securing means being integral with said body and formed as a substantially helical flange outwardly and radially extending from the outer face of said body, whereby constant rotation of said body causes said flange to increasingly engage said puncture site until said head contacts the exterior surface of said puncture site.
