A wearable device includes a wearable device main body, a sensor part configured to contact a skin surface of a user of the wearable device, and measure a bio-signal of the user, and a shock absorber that is interposed between the wearable device main body and the sensor part to mechanically connect the wearable device main body and the sensor part, and that is configured to reduce motion transmission between the wearable device main body and the sensor part to permit the wearable device main body to move independently from the sensor part.

A neuromonitoring system utilizes transcutaneous, trans-abdominal nerve root stimulation to monitor the health and status of the motor neural pathways of the lower extremities during the portions of a surgical procedure in which a tissue retraction assembly is used to maintain an operative corridor. A method of monitoring the status of nerve during a spinal surgical procedure delivers a transcutaneous, trans-abdominal stimulation signal to the spine. A determination is made of a stimulation threshold required to elicit a neuromuscular response from the stimulation signal.

A biological activity detection sensor is provided that includes a motion detection sensor that detects motion of a living body, a tremor sensor that detects a tremor of the living body, and a base member that can be mounted on the living body. The base member includes a first member that is deformable in accordance with a mounted state on the living body, and a second member that is less deformable than the first member. The tremor sensor is provided in the first member, and the motion detection sensor is provided in the second member.

A system for non-invasively acquiring maternal and/or fetal biopotential signals includes a wearable device configured to be worn by a pregnant patient comprising a plurality of electrodes configured to detect maternal and/or fetal biopotential signals associated with the patient and her fetus. The system further includes a computing device configured to receive the maternal and/or fetal biopotential signals from each of a plurality of electrode pairs and select, based on processing the maternal and/or fetal biopotential signals, one of the plurality of electrodes to use as a reference electrode during a monitoring session for the patient.

An example device includes memory configured to store a measure of COPD severity of a patient and processing circuitry communicatively coupled to the memory. The processing circuitry is configured to receive an electromyogram (EMG) of the patient, receive one or more signals indicative of respiration rate of the patient, and receive one or more signals indicative of tidal volume of the patient. The processing circuitry is configured to determine, based on the respiration rate of the patient and the tidal volume of the patient, a minute ventilation of the patient. The processing circuitry is configured to determine, based on the minute ventilation of the patient and the EMG of the patient, the measure of COPD severity of the patient, and generate an indication for output that is based at least in part on the measure of COPD severity of the patient.

Methods and systems are provided for monitoring neuromuscular blockade in patients during surgical procedures. In one embodiment, a system includes a stimulator, an electromyography (EMG) sensor, a kinemyography (KMG) sensor, and a single connector configured to couple each of the stimulator, the EMG sensor, and the KMG sensor to a patient monitoring device via a single input. In this way, neuromuscular transmission (NMT) monitoring in patient may be done reliably by ensuring that NMT measurement from a first sensor (EMG sensor) is in line with the measurement of the second sensor (KMG sensor).
