DRY ELECTRODES FOR ELECTROPHYSIOLOGY MEASUREMENT

Apparatuses for making electrical connections in electrophysiological measurements and monitoring are disclosed. One such apparatus includes a first side having an electrical contact; a second side opposing the first side and having an electrode disposed over the second side; and a layer disposed between the first side and the second side. The layer is adapted to remove moisture from a region around the electrode. The apparatus also has an electrode line in electrical contact with the electrode disposed over the layer on the first side and extending over the layer on the second side. The electrode line is electrically connected to the electrical contact.

Protective circuitry for external sensing applications
11751790 · 2023-09-12 · ·

Galvanic corrosion of an external electrode of a physiological signal sensor (e.g., ECG sensor) can be reduced. In some examples, protective circuitry, such as a switching circuit, can be used to reduce galvanic corrosion. In a first mode of operation (e.g., corresponding to measurement by the physiological signal sensor), the switching circuit can provide a low-impedance path (e.g., from an external electrode to ground). In a second mode of operation (e.g., corresponding to non-measurement by the physiological sensing system), the switching circuit can provide a high-impedance path to reduce leakage currents (e.g., between the external electrode and ground), and thereby reduce galvanic corrosion.

A method for managing an alarm issued by a medical device being used to treat a patient is disclosed. The method includes the steps of receiving an alarm from the medical device, retrieving a dynamic attribute associated with the patient, assigning a sub-priority to the alarm based in part on evaluation of the dynamic attribute, and providing an alert to a staff member that is associated with the sub-priority.

DRY ELECTRODE ADHESIVE

The present invention relates to an ionically conductive pressure sensitive adhesive composition useful as an electrode adhesive, which is an ionically conductive (meth)acrylate based pressure sensitive adhesive allowing prolonged biosignal monitoring times without skin irritation and loss of signal quality.

NEUROLOGICAL ELECTRODE SYSTEM FOR MAGNETIC RESONANCE ENVIRONMENTS

An electrode system includes an electrode, a connector, and a cable with an in- line radio-frequency filter module comprising resistors and inductors without any deliberately added capacitance. The resistors are arranged in an alternating series of resistors and inductors, preferably with resistors at both outer ends, and connected electrically in series. The in-line module is located at a specific location along the wire, chosen through computer modeling and real-world testing for minimum transfer of received RF energy to a patient's skin, such as between 100 cm and 150 cm from the electrode end of a 240 centimeter cable. The total resistance of the resistors plus cable, connectors and solder is 1000 ohms or less; while the total inductance is roughly 1560 nanohenries. The inductors do not include ferrite or other magnetic material and are, together with the resistors, stock components thereby simplifying manufacture and reducing cost.
