Puncture site patch with post injection safety sealing

A technique provides a modular sensing device having multiple separable modules attached end to end. The modules are selectable based on mission requirements, with different modules and combinations thereof selected for different mission types and/or requirements.

Modular sensing device, system, and method

A circuit tester device for testing continuity and polarity of vehicle relay circuits may include a housing and a plug carried by the housing. The circuit tester device may also have a battery lead adapted to connect to a battery terminal, and a ground lead adapted to connect to a ground. Further, the circuit tester device may have circuitry including three or more circuits connected between the battery and ground leads. Each circuit may have in series a first resistor, a first status indicator, a first diode, a test terminal, a second diode, a second status indicator and a second resistor. Each test terminal may be connected to a respective one of the pins. The circuitry may also have one or more load circuits tapped into one of the circuits between the first and second diodes. The load circuits may include in series a test switch and a load terminal.

An elastomeric puncture site patch for adhering to skin and antiseptically covering the skin at an area where a sharp object such as a syringe needle or intravenous is to be inserted. The patch is comprised of an elastomeric transparent self-sealing membrane and a spacer having an aperture. The spacer has an adhesive film on the surface opposite the membrane for adhering the patch to the skin. When the patch is applied to an area of the skin, a chamber is formed between the skin and the membrane and bounded by the spacer. In use, the skin is antiseptically cleaned and the patch applied. The syringe needle or similar device punctures the membrane and the skin. At the end of the procedure the needle is withdrawn and any blood remaining on the outside of the needle or oozing from the wound is trapped in the chamber, thus preventing contamination of the area beyond the chamber. A method of manufacturing the puncture site patch is also provided.

A flash chamber having a self-closing valve for use with a catheter is described. The flash chamber, which is connected to the catheter, precludes blood leakage as a needle is removed from the catheter and an IV unit is coupled to the catheter. The flash chamber permits the practitioner to visually verify that a blood vessel has been punctured and includes a self-sealing valve that prevents blood from flowing out of the flash chamber as the needle is removed and the IV unit is attached.

A sterilized supply kit that provides the medical practitioner with the accessories necessary for marking an injection or withdrawing blood from a patient, or both. The kit includes one or more sterilizing agents, needles, syringes, fluid collection tubes, and absorbent pads. The absorbent pads are designed to cover the sight of skin puncture and create a bodily fluid barrier that makes the use of gloves to protect the practitioner unnecessary. The kit may additionally contain a tourniquet, a sterile sheet and/or medication to be administered. All the components of the kit are contained within a sterile sealable packet.

Method and kit for making injections and withdrawing blood without the use of protective gloves

A blood withdrawal patch for facilitating withdrawal from a patient and for confining blood from the needle wound has an absorbent pad with a first surface to be placed against the skin of a patient around an intended injection site, a second surface opposite the first surface and a central opening. A transparent, elastomeric, self-sealing membrane through which an injection needle can penetrate lies in the pad central opening. A transparent cover layer has a central opening substantially aligned with the central opening of the pad to expose a central portion of the membrane to identify the withdrawal site, the cover layer being adhered to the membrane and the pad. The patch is adhesively held on the patient's skin. A blood vessel is visually located through the membrane and cover and a needle is passed through the membrane and the patient's skin into the vessel for blood withdrawal. After withdrawal, the needle is extracted, and the membrane wipes the needle and forms a cavity with the pad and the patient's skin to contain blood from the withdrawal site until after hemostasis. The patch is also useful for installation of a catheter.

Blood withdrawal patch

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.

Injection patch

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.

IV tube support assembly

A method of securely attaching for indefinite periods banners of flexible plastic electrostatically chargeable material to flagstaffs and then onto smooth non-porous surfaces, which may be the painted exteriors of vehicle bodies, and vice versa, without the use of separate adhesives.
