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.

Hemostatic transdermal injection appliance

A transdermal injection appliance has a pad impregnated with a disinfectant solution such as alcohol, a body with adhesive for holding the pad against the skin of a patient, and a sleeve with a guide passage through the body for guiding an injection needle. A membrane puncturable by the needle is attached to the sleeve to close the passage, the membrane being self-sealing so that an opening through the membrane formed by the needle is closed as soon as the needle is extracted, thereby wiping a majority of blood from the needle and preventing the escape of blood. The tubular sleeve can have an outer end with a coupling for connection to a retractable needle injection assembly. A method of using the appliance with the retractable needle assembly to administer medication without exposing the health care giver to accidental contact with the needle is also disclosed.

Transdermal injection appliance

A needle shielding and use-facilitating apparatus has a first sleeve with a coupling at one end for attachment to a syringe and a hypodermic needle carried by the first sleeve. The needle extending beyond the opposite end of the first sleeve. A second sleeve is slidably received in the first sleeve and surrounds part of the needle which extends beyond the first sleeve. A spring in the first sleeve urges the second sleeve out of the first sleeve. An end coupling is attached to the second sleeve and is selectively attachable to any of a plurality of articles puncturable with the needle.

Retractable injection needle assembly

An assembly for supporting and storing an intravenous supply tube and coupling device having a septum includes an elliptical body capable of having the tubing wound thereon and first and second flanges extending radially outwardly from the body. Each flange includes one or more slots for removably receiving the tubing and securing the tubing in place. The assembly is able to hold the tubing and coupling in place while a hypodermic needle is inserted into the coupling to shield the operator's hand to thereby reduce the risk of injury to the operator. In further embodiments two or more assemblies are coupled together in a ganged fashion.
