ABSTRACT:
A hypodermic device includes a hollow needle having a sharp distal end and a proximal end opposite thereto, a safety cap member provided with an aperture, and a holder or connector coupled to the cap member and the needle for mounting the cap member essentially permanently to the needle so that the cap member covers the distal end of the needle in a storage configuration of the needle and the cap member. The connector member enables a displacement of the cap member relative to the needle so that the distal end of the needle may be extended from the cap member through the aperture. The connector member also serves to return the cap member to the storage configuration relative to the needle upon removal of the distal end of the needle from a skin surface of a patient.
