Therapeutic cushions having a plurality of inflatable columnar cells, pumping mechanism, and a manifold or valve system for moving a fluid between the pumping mechanism and the inflatable columnar cells. The inflatable columnar cells are constructed such that inflation and deflation of the cells cause vertical expansion/contraction of the cells with limited lateral expansion/contraction. The manifold or the valve system connect the pumping mechanism with the inflatable columnar cells such that a plurality of zones are created. A valve assembly can include a plurality of valves and is adjustable among at least three valve configurations to vary fluid connections to the inflatable columnar cells to produce rearwardly advancing waves. A venting manifold may vent air from the cells between the cushions.

A walking assist device includes a pair of link members rotatably connected to each other at an output shaft situated at a location corresponding to a knee of a user, one link member being fixed to a thigh side of the user, and another link member being fixed to a lower leg side of the user, a rotary damper that generates a resistance force that is conveyed to the output shaft and that acts against rotation of the link members around the output shaft, a one-way gear that limits the resistance force generated by the rotary damper to one of directions of the rotation of the link members around the output shaft, and a clutch that switches between conveyance and non-conveyance of the resistance force from the rotary damper.

A flexible wearable robot for assisting with a walking motion of a user may include a thigh strap to be worn to enclose a thigh portion of a user, a shank strap to be worn to enclose a shank portion of the user, a driver to be worn on a back or waist portion of the user to provide a driving force for assisting with a walking motion of the user, a first driving wire with one end connected to the thigh strap and the other end connected to the driver to receive tension, a second driving wire with one end connected to the shank strap and the other end connected to the driver to receive tension, and a controller to control a drive of the driver to selectively apply tension to at least one of the first driving wire and the second driving wire.

The disclosure belongs to the technical field of lower limb exoskeleton, and specifically discloses a hip-knee passive exoskeleton device based on clutch time-sharing control, comprising a waist support subassembly, connection subassemblies, thigh subassemblies, clutch subassemblies, shank subassemblies and elastic member subassemblies, the waist support subassembly is configured to be connected to the waist, the connection subassemblies are configured to include two connection subassemblies which are arranged in bilateral symmetry on two sides of the support subassembly, the thigh subassemblies are configured to include two thigh subassemblies which are respectively connected to the two connection subassemblies, the clutch subassemblies are configured to include two clutch subassemblies which are respectively mounted on the two thigh subassemblies, the shank subassemblies are configured to include two shank subassemblies which are arranged in bilateral symmetry below the two thigh subassemblies, the elastic member subassemblies are configured to include two elastic member subassemblies which are arranged in bilateral symmetry. The disclosure can assist the movements of the knee and hip joints, thereby improving the energy utilization efficiency and reducing the metabolic energy consumption of walking.

In various embodiments, provided herein are systems, methods, processes, and devices for providing locomotive rehabilitation to a subject via one or more gait motions that substantially accurately mimic motions performed in healthy, natural gait cycles. The system may mimic natural gait motions via footplates and handles, and one or more linkage systems. In particular embodiments, the system may further include a motor unit and/or clutch for providing controlled forces assisting or resisting motions of a linkage system. Further, the system may include a tower for operating in a standing or seated position. In at least one embodiment, the system includes a body weight support system that provides offloading forces to a subject.

A massage device includes a base, a drive unit, and a transmission unit. The drive unit is coupled to the base. The transmission unit is disposed at one side of the base. The drive unit includes a drive member to drive a rotary shaft for driving massage members. One end of the rotary shaft is provided with a unidirectional bearing and a first bevel gear. The unidirectional bearing is able to control the rotation of the first bevel gear. The transmission unit includes two positioning blocks and a worm shaft connected between the two positioning blocks. The worm shaft is provided with a second bevel gear and a movable member thereon. The first bevel gear meshes with the second bevel gear. When the first bevel gear is rotated, the second bevel gear is driven to link other parts so that the drive unit can slide on the base.

A device for compressing the chest of a cardiac arrest victim.

Walking frame (10) with wheels (12) comprising a support frame (11) and two gripping elements (13) associated with the support frame (11) that can be gripped by a user.

The present concerns a wearable underactuated active robot with a couple of robotic joint adapted to correspond with to a couple of body joints in line on a limb of an user.

A wearable apparatus for the treatment or prevention of osteopenia or osteoporosis, stimulating bone growth, preserving or improving bone mineral density, and inhibiting adipogenesis is disclosed where the apparatus may generally comprise one or more vibrating elements configured for imparting repeated mechanical loads to the hip, femur, and/or spine of an individual at a frequency and acceleration sufficient for therapeutic effect. These vibrating elements may be secured to the upper body of an individual via one or more respective securing mechanisms, where the securing mechanisms are configured to position the one or more vibrating elements in a direction lateral to the individual, and the position, tension, and efficacy of these vibrating elements may be monitored and/or regulated by one or more accelerometers.
