A portable air treatment system configured to be carried by an individual and deliver air, via a mask, to the individual, is provided. The system includes an air inlet allowing atmospheric air to enter at an air flow rate ranging between 2 liters/min to 10 liters/min, an air compression system connected with the air inlet for compressing the incoming air, thereby increasing the temperature of the air to a minimum temperature of 170° C., a hot air chamber connected with the air compression system for receiving the heated air from the air compression system and retaining the heated air for a period of 30-100 milliseconds, an air decompression system connected with the heated air chamber for expanding the heated air thereby decreasing the temperature of the heated air to a temperature ranging between 14° C. to 45° C., and an air outlet connected with the air expansion system for directing the cooled air to the individual via the mask.

Compression-based portable air treatment systems and methods

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.

System and method for high density electrode management

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.

Neuromonitoring systems and methods

The present specification discloses an intraoperative neurophysiological monitoring (IONM) system including a computing device capable of executing an IONM software engine, a stimulation module having multiple ports and various stimulation components and recording electrodes. The system is used to implement transcranial electrical stimulation and motor evoked potential monitoring by positioning at least one recording electrode on a patient, connecting the stimulation components to at least one port on the stimulation module, positioning the stimulation components on a patient's head, activating, using the IONM software engine, at least one port, delivering stimulation to the patient; and recording a stimulatory response on the patient.

Systems and methods for dynamically switching output port cathode and anode designations

An intraoperative neurophysiological monitoring (IONM) system for identifying and assessing neural structures comprises at least one probe, at least one reference electrode, at least one strip or grid electrode, at least one sensing electrode, and a stimulation module. Threshold responses determined by stimulation during a surgical procedure are used to identify and assess functionality of neural structures. The identified neural structures are avoided and preserved while diseased or damaged tissue is resected during said surgical procedure.

Systems and methods for dynamic neurophysiological stimulation

A training simulator for intraoperative neuromonitoring (IONM) systems includes channels where at least one of the channels is identified as an active stimulation channel and a subset of the rest of the channels is identified as reference or pick up sites. Channels of the subset having signal data that exceed a predefined threshold are retained for further processing, while channels with signal data that do not exceed the threshold are eliminated from further reporting. Response data for the remaining channels are generated in advance of a future time when the response would occur. The generated data is time stamped and stored for display at a time window when requested by the system.

Controller, adapter and connector systems for high density electrode management

A system for deploying an electrode array at a target location through a hole formed in the patient's cranium. The system includes an array of electrodes attached to a substrate and an inserter attached to the substrate and/or the array of electrodes. The inserter, substrate and array of electrodes are configured into a first compressed state and are positioned within the lumen of a cannula. Using the cannula, the system is inserted through the hole, the cannula is then removed, and the inserter is used to transition the substrate and electrode array from the first compressed state to a second uncompressed state, thereby deploying the array of electrodes at the target location.

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.

Methods and systems for operating an intraoperative neurophysiological monitoring system in conjunction with electrocautery procedures

Neurophysiological monitoring training simulator

An electrode management solution for neuromonitoring applications such as electroencephalography (EEG) procedures provides for the verification of the locations and connections of electrodes. The brain is modeled as a volume conductor and an expected attenuated signal generated by an electrical signal present in the form of an electrical dipole at any other point in the brain is calculated. A known signal is connected between electrodes at 'presumed' locations. This action generates a defined electrical field which can be measured between any of the other electrode locations. The amplitude and phase of the measured signals are a function of the input signal, the volume conductor, and the geometric relations of the two electrodes. By comparing the expected values with the measured values, the relation between the electrodes is verified.
