Abstract
An injection patch for facilitating injection into a patient and for confining blood from the injection wound has an absorbent pad against the skin of a patient around an intended injection site and a second surface. An elastomeric, self-sealing membrane through which an injection needle can penetrate lies against the second surface of the pad and closes the central opening. A cover layer with a central opening overlies the membrane and exposing a central portion of it to identify the injection site. The patch is adhesively held to the patient's skin. An injection can be made with a needle passed through the membrane and the patient's skin, after which the needle is extracted while the membrane wipes the needle, reseals and forms a cavity with the pad and the patient's skin to contain blood from the injection site until after hemostasis.
