ABSTRACT:
An elastic, hemostatic appliance for application to the skin of a patient has a first layer of foam material having a proximal surface and a distal surface relative to the patient and an annular layer of foam material having a distal surface adhered to the proximal surface of the first layer, a proximal surface and a central cavity extending entirely through the annular layer. The proximal surface of the annular layer has adhesive for adhering to the skin of the patient. A continuous elastomeric membrane extends across the central cavity adjacent the first layer and closing the distal side of the cavity. A layer of hemostatic material is in the cavity adjacent the membrane, the hemostatic layer having a distal surface against the membrane and a proximal surface exposed through the cavity to a fenestrated membrane so that when the appliance is placed on the skin of a patient with the proximal side of the cavity toward a wound, the annular body inhibits flow of body fluids along the patient's skin and the hemostatic layer encourages hemostasis when contacted by body fluids from the wound. The fenestrated membrane closes the proximal opening of the cavity adjacent the hemostatic layer to promote passage of body fluids to the hemostatic layer. A needle guide with a coupling part at its distal end can be provided for attachment to a mating coupling part of a self-sheathing, retractable needle assembly for closed system injections.
