Abstract: Un montaje (106) de electrodo de deteccion de biopotencial de CD se proporciona para un aparato (10) para detectar los biopotenciales de CD en la piel de un paciente. Los electrodos (106) incluyen un medio electroconductor (158) para transmitir iones de la piel, el cual tiene un contenido de cloruro dentro de un rango de 6-15 gramos de ion cloruro por cien gramos de tal medio. Para reducir el efecto corrosivo de este medio electroconductor, cada electrodo incluye solamente un componente metálico (122, 144) y para proporcionar un electrodo con una impedancia de CA baja, este metal es recubierto uniformemente sobre los cuerpos del detector no metálico (120) y la terminal (142) con un recubrimiento de espesor dentro de un rango de 0.0012 cm a 0.0038 cm (de 0.5 a 1.5 milésimas de pulgada). Para asegurar una trayectoria eléctrica completa a través de ambos de los cuerpos del detector y la terminal, las porciones no metálicas (120, 142) se forma de plástico conductor.

Abstract: An electrocardiograph sensor positioning device includes a pair of sensor locating members (12,14) that are angularly adjustable with respect to each other to a determinable angular position. Co-operative indicia means (50,72) provided on each of the sensor locating members furnish an indication of the relative angular position therebetween. Each of the sensor locating members defines a plurality of location zones (34,38: 56-64) for positioning of the electrocardiograph sensors and indicia means (40,42,68) are provided alongside the location zone to determine the precise location of the electrocardiograph sensors when they are positioned in the location zones. The electrocardiograph sensor positioning device thus permits the establishment of reference paths on the human anatomy which are used to locate the positions of the electrocardiograph sensors. The size and extent of the reference paths and the pivotal arrangement of one of the sensor locating members permits adaptation of the device to a relativey wide range of anatomical size and shape regardless of sex.

Abstract: A clip-type electroae T or an electrocardiograph includes a pair of clamping plates (12,13) for being opened and closed relative to each other about a common shaft (11) and having concave surfaces (16, 17) facing each other, an electrode member (19) mounted on one of the clamping plates (12), and a leaf spring (18) bent into a U-shaped configuration for biasing ends of the clamping plates (12, 13) remote from the common shaft (11) towards each other. Each of the pair of clamping plates (12, 13) has a slot (37, 38) at a position adjacent to the shaft (11) for accommodating the leaf spring (18) passed therethrough, and a plurality of grooves (41, 42, 43, 41', 42', 43') formed in an outer surface (16a, 17a) thereof and spaced at successively greater distances from the shaft (11). One end of the leaf spring (18) is fitted into a one of the plurality of grooves (41, 42. 43) in one of the clamping plates (12), and the other end of the leaf spring (18) is fitted into one of the plurality of grooves (41', 42', 43') in the other (13) of the clamping plates, the grooves being chosen based upon the thickness of a limb, such as the wrist or ankle of a human body, that is to have the clip-type electrode attached thereto. The limb can thus be clamped with a prescribed clamping force irrespective of the thickness of the limb.

Abstract: @ A multipolar medical electrode (E, C) is attachable to the skin of a patient for deriving separate electrical signals from spaced locations indicative of physiological activity. A flexible pad (10) of nonconductive material has a pair of well members (12) which each contain an electrolytic gel (20) to make contact with the patient's skin when backing (26) is removed to expose an adhesive (24). An electrical connector (C) for connecting the electrode to an electrical potential measuring instrument includes a nonconductive body (32) having a pair of spaced conductive prongs (34) connected by wires (40) to an electrical potential measuring instrument. The prongs (34) are inserted respectively through puncturable membranes (48) in the respective well members (12), making intimate contact with the electrolytic gel (20). A generally box-shaped housing (42) is attached to the nonconductive body (32) and protects the prongs (34) and slidably engages the outer surfaces of the well members (12) to assist in guiding the prongs (34) into the well members (12).

Abstract: A heart-beat rate indicator comprises a detection electrode (1) receiving an electrocardiac potential signal, circuitry (2, 3,4,5, 6) receiving the electrocardiac potential signal and determining therefrom a heart-beat rate and a switching element (7), for example a P-channel MOSFET, one side of which is connected to the detection electrode and an input of the circuitry and the other side of which is connected to ground potential. A switching circuit, for example, comprising a mechanical switch and a flip-flop circuit controls the conductive state of the switching element.

Abstract: A cardiac pacer has separate digital filter circuits for sensing atrial and ventricular activity. Parameter data stored in memory is used by the digital filters for identifying the various components of cardiac activity, such as the P, R and T waves, as well as for identifying Premature Ventricular Contractions (PVC). A Ventricular Rate Time Out period is established from the last natural beat or stimulating pulse; and if a P wave or natural R wave is not sensed during that period, the system generates a stimulating pulse and, using T wave parameters in the ventricular filter, tests to verify capture. Loss of capture increases stimulating pulse width and amplitude to regain capture.
