A walking assist device has a frame, a plurality of wheels, drive units, a battery, and a drive control unit that controls the drive units. The walking assist device also has: a pair of right and left movable handles that are grasped by a user and movable back and forth with respect to the frame in accordance with arm swing performed during walk of the user; handle guide units provided on the frame to guide the movable handles in a movable range that matches the arm swing performed during walk of the user; and a grasp portion state detection unit that detects the state of the movable handles. The drive control unit controls the travel speed of the walking assist device by controlling the drive units on the basis of the state of the movable handles which is detected using the grasp portion state detection unit.

A massage apparatus includes a sheet member attachable to a skin of a body, and a pressure unit that presses the skin from the sheet member. The sheet member is elastic and thermoplastic such that the sheet member is hardened at a temperature of the skin and is softened at a predetermined temperate different from the temperature of the skin. The sheet member has one or more indications indicating an area of the skin to which the sheet member is to be attached. The pressure unit applies a pressure to the skin so as to provide a predetermined pressure distribution in which positions of the pressure distribution are defined with reference to one or more positions on the body in a situation in which the sheet member is attached to the area.

A medical device for measuring an impedance of a patient or mammal when a current is applied by electrodes. The medical device includes an output transmits a drive signal to a set of drive electrodes coupled to a patient and an input receives a sense signal generated by a set of sensing electrodes coupled to the patient. A processor determines the impedance of the patient based on the drive signal transmitted to the set of drive electrodes and the sense signal received by the set of sensing electrodes.

A multimodal optical imaging platform is used to obtain cerebral perfusion-metabolism mismatch metrics for rapid assessment of acute brain injury, ongoing (real-time) feedback to optimize cardiopulmonary resuscitation to improve neurological outcome, and rapid prognosis of recovery. Light of several wavelengths and types is delivered to the tissue, which is then absorbed and scattered by tissue components such as blood and cellular components. Some of this light scatters back to the surface, where it is captured by a detector. The resulting data are processed to obtain blood flow and oxygenation parameters, as well as tissue scattering. These parameters are then combined to calculate metabolism and flow-metabolism coupling/decoupling metrics, which are used to determine ischemic damage, ongoing need for optimal blood flow and oxygenation, and to predict cerebral recovery in patients with acute brain injury during and immediately after cardiac arrest, stroke, traumatic brain injury, etc.

A compression device for applying pressure to a body part can include a fabric member that can fit over the body part, and one or more actuators coupled to the fabric member, wherein each of the one or more actuators is configured to cause at least a portion of the fabric member to expand or contract along a circumferential direction, thereby decreasing or increasing the pressure applied to the body part adjacent to the actuator. The fabric member can be thin and stretchable, and can contour the body part over which it is worn. The actuators can cause user controlled variable pressure levels to be applied to the body part, including constant pressure levels as well as time varying synchronous or asynchronous pressure patterns.

A respiration-assistance apparatus or method can include or use a lifting element such as to cyclically push, pull, or lift, toward a superior direction of the subject, at least one subject region during an inhalation portion of a respiration cycle of the subject. A cyclical member can couple the lifting element to a fixed reference. Abdominal or ribcage compression can be provided. A multi-action or other cam can be used, such as together with a reciprocating element. Examples can be configured for use with a wheelchair, a bed, a vacuum or suction affixation element, a wearable garment, etc.

A wearable ultrasound device and method of using the device includes a power controller with a power source and at least one integrated circuit that delivers electrical power to an applicator. The applicator is electrically coupled to the power controller and a surface of the applicator transmits ultrasound to a wearer for a given duration. The applicator includes radio frequency (RF) drive electronics, an ultrasound transducer coupled to the drive electronics, a monitoring apparatus that includes a thermal cutoff coupled to the drive electronics, where the monitoring apparatus monitors a temperature of the applicator surface and the thermal cutoff turns off the applicator, if the temperature exceeds a pre-defined threshold, and a coupling bandage coupled to the applicator, where the bandage positions the surface of the applicator proximate to a wearer at a location on the body of a wearer.

A percussive therapy system includes a percussive therapy device that includes a housing, an electrical source, a motor positioned in the housing, a switch for activating the motor, a push rod assembly operatively connected to the motor and configured to reciprocate in response to activation of the motor, and an attachment configured to be operatively connected to a distal end of the push rod assembly of the percussive massage device and to provide at least one therapeutic effect to a user. The attachment may include at least one of an actuator configured to provide the at least one therapeutic effect to the user and a sensor configured to obtain at least one of biometric data of the user and information regarding operation of the percussive therapy device.

A system for assisting with a cardiopulmonary resuscitation (CPR) treatment being administered to a patient. In one aspect, a system for assisting with a cardiopulmonary resuscitation (CPR) treatment being administered to a patient includes a sensor for determining a parameter of the patient (e.g., indicative of a blood flow or pressure waveform), and one or more processors configured for receiving input from the sensor, determining, based on the input from the sensor, whether a rate of chest compressions administered in the CPR treatment should be changed, and providing an indication to a user that the rate of chest compressions should be changed.

An assistance apparatus for carrying out a first emergency care procedure, such as chest compressions or pulmonary ventilation, is configured to cooperate with a second assistance apparatus for carrying out a second emergency care procedure. The assistance apparatus comprises a communication device designed to receive, from the second assistance apparatus, data relating to the second emergency care procedure. The data comprises at least one item of information, a parameter or an instruction. A signal-processing device is configured to process the at least one signal measured according to the received data relating to the second emergency care procedure. An assistance system, comprising a compression assistance apparatus and a ventilation assistance apparatus, and an assistance method associated with the assistance system are also disclosed.
