摘要： 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.

摘要： An electrode system for neurological monitoring is disclosed, including a housing with a recess dimensioned to hold an electrode. A conductive gel is applied to said electrode to limit direct contact by said electrode to a patient's skin. The recess defines a wall in said housing that engages the patient's skin. A thin bead of adhesive applied to the top surface of the wall secures the housing, and therefore the electrode, to the patient. Finer electrical conductor wires in a more flexible insulator lead from the electrode to a connector that fits into a neurological monitoring amplifier. The electrode system further comprising a template structure for precisely locating and adjusting to a patient's dimensions.

摘要： An electrode assembly for use in computer tomographic (CT) scans and magnetic resonance imaging (MRI) procedures include lead wires of 40 gauge copper electrical conductors, free of tin, in PVC insulation attached to electrodes. The electrodes, which may also be made of silver, gold or silver chloride or be made of metal-filled or metal-coated plastic, are attached to lead wires by any of the following (1) crimping using copper or polymer crimps; (2) shrink-wrap connections or ties, (3) radio frequency welding or heat staking; or (4) using conductive adhesives. The present electrode assembly reduces artifacts in the resulting images during CT scans and MRI procedures and thereby results in clearer images.

摘要： A cable management system is used in neurological monitoring and imaging procedures, particularly MRI. The system enables quickly disconnecting and quickly and accurately reconnecting the patient to the neurological monitoring equipment. The cable management system uses plural color-coded, two-part, cable pairs that include an electrode cable and an extension cable in each pair. The electrode and the short electrode cable remain attached to the patent during monitoring while the extension cable is disconnected and removed. A plug and socket combination that connects in a preselected orientation that enables the two parts to be quickly and accurately disconnected and reconnected. Metal is minimized in the electrode and electrode conductor in part by its short length, it thinness, the use of metal coating on plastic electrodes, and the use of alternative conductive materials.

摘要： An electrode assembly includes a handle, holder, and electrode with an electrical conductor. The electrode is loaded into the holder with its attached conductor. The holder includes a protective cap, a resilient button with a flange, an alignment ring, two plungers each with a spring, and a retention ring. The flange and retention ring both have plural holes in registration and with posts depending from the alignment ring in order to hold the retention ring in place. Inside the button are two plungers, one on top of the other, and each with its own spring resisting downward pressure. Once the cap is removed from the button, the holder is placed against the skin of a patient, and the button is pressed, the top plunger pushes the bottom plunger against the skin of the patient and then the electrode from the protection ring, thereby ejecting the electrode.

摘要： A method for placing electrodes on a patient uses a mobile device with built-in camera to generate a customized, virtual electrode template for neurological monitoring. The camera captures a digital image of the patient and is programmed to find landmarks, use analysis, and respond to manual input for electrode locations and generate a virtual electrode template. Facial recognition and edge detection software determines the outline of the patient's head when in the field of view of the camera monitor. The user then may assist the camera in identifying landmarks on the patient's head, such as the nasion, the inion, and the pre-auricular points, to facilitate generation of the virtual electrode template on the image in the camera's viewfinder, which template moves and rotates with the patient. The virtual electrode template guides the user in establishing a set of electrodes on the patient's head for neurological monitoring.

摘要： An electrode assembly includes a needle and a conductive thread electrode carried in a slot on the surface of the needle. The needle pushes the thread electrode into the body and leaves it in place when the needle is removed. The needle is secured in a housing in a retracted position and moved to an extended position by a latch. In the extended position, one end of the needle remains in the housing and the other end extends from the housing. The needle is attached to a spring inside the housing and is moved by the latch against the urging of the spring to the extended position and locked in place. A protective cover is applied over the needle while extended and removed to insert the needle into the body of a patient.
