Abstract: A shoe electrode comprising an electrode, a skin adhesive for attaching the electrode to the skin, an electrically conductive heel pad, and a conductive pathway between the electrode and the heel pad. A removable adhesive is used to attach the heel pad to the heel of a shoe and in one embodiment, the electrode, heel pad and conductive pathway are formed as a single piece of conductive vinyl film.

Abstract: A method for using a needle electrode system for acquiring biopotential signals from a person's body. The needle electrode system comprises at least one silver-silver chloride needle electrode and at least one connector coupled with a monitoring device. The needle electrode system senses and sends biopotential signals to the monitoring device in preference to cutaneous electrode on the person's body by inserting the needle electrode subcutaneously into the person's body.

Abstract: A replacement adhesive unit for optimizing adhesion to a disposable ear coupler and an ear of an infant comprises at least one adhesive layer that can be attached to a skin side flange of the disposable ear coupler, at least one structural tie layer to attach with a bottom side of the adhesive layer, and at least one adhesive ring having a top side and a bottom side, the top side being attached at a bottom surface of the structural tie layer. The structural tie layer provides structural support to the replacement adhesive unit and the application of at least one surface tape and the replacement adhesive unit in a laminated arrangement makes the disposable ear coupler reusable.

Abstract: An electrode arrangement for low artifact electrocardiogram (ECG) monitoring and defibrillation, comprises at least one conductor print line body having a large silver conductor print line area functioning as a defibrillation area and a small silver-silver chloride (Ag/AgCl) conductor print line area functioning as a sensing area, at least one non halide defibrillation gel layer and halide containing sensing gel layer configured to attach with the defibrillation area and sensing area respectively, and at least one insulated conductive ink line for connecting the conductor print line body to a cable that provides an electrical communication between the conductor print line body and an external equipment. When direct current runs through the conductor print line body, the large silver conductor print line area polarizes and the small Ag/AgCl conductor print line area does not polarize so that small Ag/AgCl conductor print line area senses ECG signal leading to low motion artifact.

Abstract: A needle electrode system for acquiring biopotential signals from a person's body. The needle electrode system includes at least one silver-silver chloride needle electrode that is coupled to a distal end of a first wire, at least one cutaneous electrode connector coupled to a distal end of a second wire and at least one connector attached to at least one proximal end of the first wire and the second wire. The connector is coupled with a monitoring device. The first wire and the second wire are made of carbon fiber. The non-polarizable needle electrode that is made out of or coated with silver-silver chloride has a protective safety cover. The needle electrode system senses and sends biopotential signals to the monitoring device in preference to cutaneous electrode on the person's body by inserting the needle electrode subcutaneously into the person's body.

Abstract: A sensor device in the form of a substantially flat package for receiving and transmitting signals, to be monitored and/or recorded, comprising, in combination a first layer in the form of an annulus having an undersurface to adhere to the skin of a patient; a second layer in the form of a conductive sensing layer peripherally bounded by the first layer and having an undersurface adapted for contact with the skin of the patient; a conductive terminal extending above the second layer in adjacent and conductive relation therewith; a protector extending in shallow dome configuration over the first and second layers and over the terminal; and a conductive lead extending over edges defined by the first and second terminals, and under the protector, for protected contact with the terminal, and to transmit signals for monitoring or recording.

Abstract: An earphone assembly is disclosed that includes an annular baffle having an outer surface and an inner surface as well as an interior wall and an exterior wall. The interior wall defines a central chamber. A transparent, flexible lid is attached to the baffle along the outer surface, completely covering the central chamber and forming an acoustic seal with the baffle. The lid has an inner face and an outer face. The flexibility of the earphone is improved by creating hinges in the lid and by providing cuts, or other discontinuities, in the baffle. For example, a radial cut may be disposed in the annular baffle. Further, a circumferential cut may also (or alternatively) be disposed in the baffle, extending from the inner surface and disposed between the exterior wall and the interior wall. At least one hinge may be disposed on the flexible lid. To improve the attachment of the earphone to the patient's head, tabs are mounted to the exterior wall.

Abstract: A physiological sensor device for attachment to a mammalian subject including first and second regions of sensors attachable to a subject in use, which first and second regions of sensors are separated by a flexible web adapted to enable variable separation of the first and second sensor regions from one another in use. The physiological sensor device is manufactured by forming a strip of electrically conductive material on a flexible electrically non-conductive substrate and cutting a slot through both the flexible substrate and conductive strip to define a pair of adjacent edges of conductive material separated by a non-conductive gap thereby also to define adjacent electrode sensors each having one of the pair of adjacent edges formed in the strip of conductive material. The physiological sensor device is attached to the subject for measurement of numerous physiological parameters for a period of time, such as 24 hours, and is then thrown away.

Abstract: A skin mounted device holder for holding generally medical devices such as fluid reservoirs. The skin mounted device holder includes a base member comprised of a resilient cloth material and having a VELCRO attached to its top surface and a water based adhesive material coated onto the bottom of its surface, a securing flap having a VELCRO for mating with the VELCRO of the base means, and a connector loop having an attachment for attaching medical devices. The connector loop loops around the securing strap and thus connects the medical devices to the base member.
