A portable cardiopulmonary resuscitation (CPR) system includes a first module hub housing, an inflation actuated soft gripper configured to receive an inflation gas, and in response, to change form to a deployed grip state that accommodates and grips a human torso. Features of the portable CPR system include modularity for in-the-field reconfigurability, in which a second module hub housing attaches to the first module hub housing, carrying a CPR pressure applicator configured to receive an actuator power and a CPR control signal causing, concurrent with the deployed grip state, cyclic extension and retraction of the CPR pressure applicator along an axis aligned with a sternum of the human torso.

A method for performing cardiopulmonary resuscitation (CPR) includes elevating the heart of an individual to a first height relative to a lower body of the individual. The lower body may be in a substantially horizontal plane. The method may also include elevating the head of the individual to a second height relative to the lower body of the individual. The second height may be greater than the first height. The method may further include performing one or more of a type of CPR or a type of intrathoracic pressure regulation while elevating the heart and the head. The first height and the second height may be determined based on one or both of the type of CPR or the type of intrathoracic pressure regulation.

A passive stent for retaining an organ in an expanded state configured to adhere and substantially conform to an external surface of the organ may include an inner layer, an outer layer, and a middle layer that is enclosed by the inner layer and the outer layer, comprising a plurality of components configured to interlock and maintain the organ in an expanded state upon application of a vacuum. A method for retaining an organ in an expanded state may include applying at least one force to the organ to place the organ in the expanded state; applying a passive stent to an external surface of the organ; and applying a vacuum to the passive stent sufficient to cause a plurality of components of at least one layer of the passive stent to interlock, where the at least one layer is configured to maintain the organ in the expanded state after interlocking.

A transportation device including a frame with a geometry and proportions that supports the body in a way that permits free movement of the lower body and legs, unencumbered by the device itself, to propel the transportation device and enable steering of the transportation device while riding with the body partially or wholly suspended off of the ground. In a portable configuration of the transportation device, a body suspension apparatus rotates in line with a central down tube and a steering mechanism rotates adjacent the central down tube. A plurality of telescoping down tubes forming the central down tube are nested within one another to reduce the length of the central down tube.

A trunk supporting exoskeleton comprises: a supporting trunk; thigh links configured to move in unison with a wearer's thighs; and first and second torque generators located on both left and right halves of the wearer substantially close to the wearer's hip. The torque generators couple the supporting trunk to the thigh links, and generate torque between the thigh links and the supporting trunk. When the wearer bends forward such that a predetermined portion of the supporting trunk passes beyond a predetermined angle from vertical, a torque generator(s) imposes a resisting torque between the supporting trunk and the thigh link(s), causing the supporting trunk to impose a force against the wearer's trunk, and the thigh link(s) to impose a force onto the wearer's thigh. When the predetermined portion does not pass beyond the predetermined angle, the torque generators impose no resisting torques between said supporting trunk and respective thigh links.

A power assist suit includes a harness worn at least around hips of a wearer, an assist unit, a power unit, and a bearing roller. The assist unit includes an arm and a thigh-worn part. A rail is provided at a part of the arm in a longitudinal direction. The rail includes channel-shaped parts extending along the longitudinal direction. The thigh-worn part is connected to sliding movable parts or integrated with at least a portion of the sliding movable parts. The bearing roller is disposed between each of the channel-shaped parts in the rail and each of inner wall surfaces of the sliding movable parts facing the respective channel-shaped parts.

A medicine application device with ultrasonic massage enabling concentrated supply of medicine, including a medicine concentrated supply device, at least one ultrasonic massage mechanism, a medicine supply pipe and power cables. The ultrasonic massage mechanism has a shell, a base panel having massage projections, and an electrical ultrasonic vibration element; the medicine concentrated supply device has a housing, a control panel, a circuit board, and a medicine supply device. The medicine application device provides high frequency ultrasonic massage and applies medicinal therapy to patients.

An assist device includes a first body-worn unit that is worn on at least shoulders or a chest of a user; a second body-worn unit that is worn on each of right and left legs or a waist of the user; a belt body provided to extend along a back side of the user, from the first body-worn unit to the second body-worn unit; an actuator provided in the first body-worn unit or the second body-worn unit and allows a part of the belt body to be reeled and unreeled; a battery configured to supply electricity to the actuator; and a controller configured to control the actuator. When a remaining charge level of the battery has decreased to a predetermined set value, the controller executes a vibrating motion process of causing the actuator to perform a vibrating motion of intermittently repeating reeling of a minute amount of the belt body.

A convertible wheelchair is provided. The convertible wheelchair can have a wheelchair configuration and a walker configuration to allow a user to alternately sit and stand, and can include a frame supporting a chair. The chair can be foldable and can include a chair back and a chair seat. The convertible wheelchair can include support and stability mechanisms accessible in the wheelchair configuration and the walker configuration including one or more torso supports, a fall seat, and stability bars.

A brace for retaining an organ in an expanded state configured to adhere and substantially conform to an external surface of the organ includes an inner layer, an outer layer, and at least one sheet of thin malleable material forming a middle layer between the inner layer and outer layer, the at least one sheet being enclosed and configured to rigidify and maintain the organ in an expanded state upon application of a vacuum. The brace can be incorporated into a brassiere.
