The present invention relates generally to an electro-mechanic assembly comprising a snap connector. In order to provide a connection interface for an electronic device having a housing with at least one protruding stud which detachably fits within a socket region of the snap connector, the electro-mechanic assembly comprises a snap and at least one material layer being in at least one portion electrically conductive to electrically connect least one electrode with the snap. At least one surface of said snap is metallic and deposited with a non-oxidizing conductive material layer which faces and is in contact with a conductive portion of the material layer.

An electrode connector adapted for attachment to a biomedical patient electrode by either pinch or snap connection includes a pair of pivotally connected members including a connector body and a jaw pivotally connected to said connector body, with the jaw defining a beveled lower surface that functions to urge the jaw open by engagement of the top surface of an ECG stud thereby allowing the connector to be attached by snap engagement. An electrically conducting plate is disposed at the bottom of the connector to maximize electrical contact with the electrode stud. The jaw member further includes a lip functioning to engage a lower portion of the head of the stud and urge the radially enlarged base of the stud into electrical contact with the bottom surface of said electrically conducting member. An ECG electrode connector in accordance with the present invention may further be fabricated of radiolucent materials.

The present invention is directed to a physiological recording device, or other types of sensors to detect a biopotential, and more particularly, a physiological recording electrode that can be used without skin preparation or the use of electrolytic gels. The invention is further directed to the configurations of structures on the physiological recording electrode's lower surface. The structures having a length, width, and height, which are capable, at least in part, of transmitting an electric potential from the skin which can be measured. The structures may or may not limit the depth of application, and/or anchor the electrode or other device during normal application, and/or allow for uniform application of the electrode or other device over unprepared skin.

The invention provides a neck-worn sensor for simultaneously measuring a blood pressure (BP), pulse oximetry (SpO2), and other vital signs and hemodynamic parameters from a patient. The neck-worn sensor features a sensing portion having a flexible housing that is worn entirely on the patient's chest and encloses a battery, wireless transmitter, and all the sensor's sensing and electronic components. It measures electrocardiogram (ECG), impedance plethysmogram (IPG), photoplethysmogram (PPG), and phonocardiogram (PCG) waveforms, and collectively processes these to determine the vital signs and hemodynamic parameters. The sensor that measures PPG waveforms also includes a heating element to increase perfusion of tissue on the chest.
