摘要： Methods and systems for conditioning a signal indicative of electrosurgical unit activity are described. A hardware circuit acquires AC current from an electrosurgical unit on patient isolated circuitry and conditions the signal in either of two alternate processing methods. The processed signal is routed as input to an analog to digital converter circuit. A method for determining saturation on referential inputs and recovering inputs to an unsaturated state is also described.

摘要： Computer-implemented methods of enabling an on-the-fly generation of at least one user-defined montage from EEG electrodes positioned in a patient's brain, on the patient's brain and/or on the patient's scalp. The methods includes generating a graphical interface to display a view of the patient's brain and/or scalp overlaid with the EEG electrodes, each of which is uniquely identified with reference to its position in the patient's brain, on the patient's brain and/or on the patient's scalp, displaying a tool within the graphical interface for selecting at least one electrode from the displayed EEG electrodes, indicating a reference electrode corresponding to the selected electrode, accessing EEG signals corresponding to the electrode and the reference electrode, and generating another graphical interface to display an EEG trace indicative of a comparison of EEG signals of the electrode and the reference electrode.

摘要： A connector receptacle for connecting with a corresponding connector plug coupled with electrodes being used for performing EMG procedure on a patient is provided. The receptacle includes a first ball bearing pressing against a first end of a housing of the plug and, preferably, a second ball bearing pressing against a first end of the housing of the plug when the plug is connected to the receptacle for exerting a retention force against the plug. The first and the second ball bearings are pressed against the first and the second ends respectively by using a spring force generated, for example, by a retention band.

摘要： Systems, devices and methods for advanced electrode management in neurological monitoring applications include receiving sockets configured to receive connectors having groups of electrodes. The physician is not required to manually map each electrode with its corresponding input channel. Electrodes are coupled to the corresponding input channels in groups through connectors having a unique identification (ID). The system is configured to read the unique ID of each connector and establish its identity. Based on the ID, the system configures itself to automatically correlate or associate each electrode with its corresponding input channel when the connectors are first inserted into the receiving sockets, and again if the connectors are removed and re-inserted into different positions in the receiving sockets, to insure the electrodes are always mapped to the same input channels.

摘要： Systems, devices, and methods are described for neuromonitoring. A minimum stimulus signal required to elicit a threshold neuromuscular response is determined by delivery of stimulus signals to tissue and detection of neuromuscular responses in muscle tissue. The strength of the delivered stimulus signals is varied, for example by adjusting the current amplitude or pulse width of the signals, and muscle responses are measure, for example by detecting EMG signals. The delivered stimuli and corresponding responses are then used to determine a stimulation threshold. The stimulation threshold may be used to indicate at least one of nerve proximity and pedicle integrity.

摘要： Systems, devices and methods are provided for neuromonitoring, particularly neuromonitoring to reduce the risks of contacting or damaging nerves or causing patient discomfort during and after surgical procedures, including spinal surgeries. The neuromonitoring procedures include monitoring for the presence of or damage to sensory nerves, and optionally includes additional monitoring for motor nerves. In some systems, including systems that monitor for both sensory and motor nerves, components of the monitoring systems (e.g., stimulating electrodes and response sensors), may be combined with one or more surgical instruments. The systems, devices, and methods provide for pre-surgical assessment of neural anatomy and surgical planning, intraoperative monitoring of nerve condition, and post-operative assessment of nerve position and health.

摘要： Systems, devices and methods are described for mounting medical equipment on IV poles, bed rails and other supporting structures in medical facilities including operating rooms and critical care sections. A system including a mounting hanger and corresponding equipment housing is disclosed that allows quick mounting and dismounting of equipment from a supporting structure. The novel structural design of mounting hanger including a symmetrical t-slot feature and a plunger lock allows a piece of equipment to be mounted on a supporting structure in multiple orientations as per the requirement which allows a user to optimize the placement of equipment in the medical environment.
