Abstract:
An absorber assembly for use in a biomedical electrode, such as an ECG electrode, comprises a contaminant absorber (18) and a support (17) which is combined with the contaminant absorber (18) to form an assembly and which has a recess (21A) for receiving an electrode member (16). An electrically insulating portion (21) of the support (17) is provided between the electrode member recess (21A) and the contaminant absorber (18). The contaminant absorber (18) also has a capillary break with respect to the electrode member recess (21A). The absorber assembly may include the electrode member (16).
Abstract:
A body electrode contains one or more galvanically active sensors connected on the body contact side with a layer (4) of electrically conductive, adhesive, elastic, hydrophilic material which adheres to the skin. The side of the sensor(s) facing the skin and the layer adhering to the skin are covered with a non-adhesive protective layer (5). The two said layers each consist of a castable polymer which is cast in a mould and then cured. The electrode can be manufactured economically by casting without stamping.
Abstract:
An apparatus for body surface mapping comprises a plurality of electrodes for attachment to spatially separate locations on a human torso and each capable of detecting the electrical activity associated with a heartbeat and producing a corresponding voltage. The electrodes are sampled at a rate of e.g. 1 KHz during a cardiac cycle and the sets of sample values so produced are stored. Positional variations of the maximum and minimum sampled values over time are displayed as a projection of the trajectories of the maximum and minimum sampled values in three-dimensional (x, y, t) space onto planes perpendicular to a plane containing the electrodes.
Abstract:
A biomedical electrode comprises a connector stud (1) anchored in a patch of adhesive-coated backing material (7) which is used to secure the electrode to the skin of a patient. The connector stud (1), which is located in a pierced opening in the backing material (7), has a head portion (2) to which an electrical lead of an electromedical monitoring/diagnostic system can be attached, and an electrode plate (3) which, when the biomedical electrode is in use, is placed in electrical communication with the skin of the patient. The head portion (2) and the electrode plate (3) of the stud are located on opposite sides of the backing material (7), which is held between the electrode plate and an integral flange (4) of the stud. A method to make the electrode is also described.
Abstract:
The present invention discloses a biomedical electrode (10) of low profile, multi-layer construction wherein an electrically conductive tab (18) contacts ionically conductive medium (16) through an aperture (14) of an insulative backing (12).
Abstract:
A biomedical electrode (10) of the type configured to be positioned on the skin of a patient to provide an electrical interface between the patient and a medical instrument. The electrode includes a backing member (12), a silver/silver chloride conductive layer (20) overlaying the backing (12) and a layer of conductive adhesive (22) overlaying the conductive layer (20). The backing (12) is formed from a sheet of conductive polymer and includes an integral snap-type connector stud (14) molded therein.
Abstract:
A process and device for making an electrode to be applied to the skin in which a support (1) with an aperture is adhesively secured on the side away from the skin, a label (4) covering the aperture. Adhesive is applied to the label (4) and/or the support only on a locally restricted partial region of their facing surfaces and the label is adhesively secured to the support (1).
Abstract:
An interface element (10B) for a biomedical electrode is independent with respect to the electrode and adapted to be placed between and in engagement with, on the side, a contact face of the electrode and, on the other side, the skin of a patient to form an electrical connection of high conductivity between the skin and the electrode. The interface element (10B) comprises a lamellar air-permeable substrate (11) which is readily expandable to dome or toroidal shape.
Abstract:
A medical electrode having a resilient terminal press fit onto an eyelet (12). The eyelet (12) is plastic and has a conductive coating thereon. The terminal (18) is made of a resilient nonmetallic composition, such as a polypropylene blend loaded with carbon fiber. An electrolyte composition (26) is spread upon the bottom of the eyelet (12) for making electrical contact with the skin of a patient. The eyelet (12), the terminal (18) and the electrolyte composition (26) are preferably all at least translucent to x-rays.
Abstract:
A connection system for bioelectrodes having a cable (12) in two sections; a reusable section (12b) adapted to be connected to the generator, and a disposable section (12a) permanently attached to the bioelectrode (10). The disposable section is provided in a sanitary condition so that the objects near the patient's body are clean, but the reusable section does not need to be sanitary; the connection between the two sections is removable from the patient and outside the sterile field. The disposable section (12a) of the cable preferably includes a simple length of insulated wire with no special adapter at the end opposite from the end connected to the bioelectrode. The reusable section (12b) of the cable preferably includes an insulation displacement type connector (38) to make electrical connection with the disposable section.
