Devices and methods for CPR chest compression with active decompression.

A joint actuator assembly includes a motor, a rotating driving member driven by the motor for driving a driven component, and a transmission assembly located between the motor and the rotating driving member that provides speed reduction from the motor to the rotating driving member. The rotating driving member comprises a magnetic coupling including a plurality of magnetic elements that are configured to magnetically couple with an opposing magnetic coupling of the driven component. The actuator and driven component may be combined into a mobility device including a magnetic coupling system having a first magnetic coupling on the actuator that magnetically couples to a second magnetic coupling on the driven component. The magnetic coupling system includes plurality of magnetic elements located as part of one or both of the first and second magnetic couplings. The first and second couplings have opposing mating surfaces that join together in a coupled position.

Disclosed are a display assembly and a walking assistance apparatus including the same. The display assembly includes a body, a rotary part coupled to the body to be rotatable about a first axis extending upwards, a display part coupled to an upper side of the rotary part, and a pressing part coupled to a side surface of the body, and that allows the constrained rotary part to be rotated in a first direction as the pressing part is pressed toward the rotary part.

A link assembly includes a main frame, a base link rotatably connected to the main frame, an input link rotatably connected to the main frame, and an output link at least 2-degree of freedom (DOF) rotatably connected to the main frame.

A translational-rotary machine is provided as a physical exercise machine particularly for the rehabilitation or training of upper and lower limbs for both passive and active therapies. The machine can perform movements that: allow a lower shaft to rotate while the carriage is stationary; allow the lower shaft to not rotate while the carriage translates in a direction of applied force; or allow a translational-rotary movement.

The invention relates to a stimulation device comprising a main part and a rubber-elastic sleeve which is intended for contact with a body part of a user and which encloses the main part and has a reversibly deformable contact surface region, wherein a shaping element, which is designed to produce a locally limited deformation of the sleeve without deformation of the main part, is arranged on the main part so as to be movable relative to the main part, and an actuating device, which is operatively connected to the shaping element in order to generate a movement of the shaping element, is arranged on the main part and comprises an electric motor having a rotor shaft to which an eccentric is fastened, and the shaping element comprises a pivotally mounted lever having two free ends, wherein a first end of the lever is operatively connected to the eccentric of the actuating device in order to convert a rotation of the rotor shaft into a pivoting movement of the lever, and a second end of the lever acts in a deforming manner on the contact surface region.

In device for placing a toe of a patient's foot in traction may broadly include a shoe portion (e.g., a sole, counter, and strap(s)); a toe attachment apparatus (e.g., a Chinese finger trap) having a cable extending therefrom; a pulley, with the cable wrapped about the pulley; and an apparatus (e.g., a ratchet, an actuator, and the like) configured to apply tension to the cable to create traction in the toe. A second actuator may adjust lateral positioning of the pulley relative to the shoe portion to set a desired angle of adduction for the traction provided to the toe by the cable. A meter may be coupled to the cable to indicate an amount of tension provided thereto. Another actuator may adjust elevational positioning of the pulley relative to the shoe portion to set a desired angle of dorsiflexion for the traction provided to the toe by the cable.

A knee joint stimulation device that can effectively stimulate a knee joint is composed of a base, a frame provided upright on the base, a center shaft provided at an upper part of the frame, a crank connecting a motor and the center shaft and driven by rotation of the motor, a swing arm hanging down perpendicularly from the center shaft, and a support plate unit provided at a lower end of the swing arm and allowing a user in a sitting position to put his/her sole thereon. With the user putting the sole on the support plate unit, the length of the swing arm is adjusted such that a pivot point of a knee joint of the user is aligned with the center shaft.

A massage motion device and a massager for scratching head, and the massage motion device includes a mounting seat and a pair of swing arm assemblies; the swing arm assemblies being mounted to the mounting seat, the swing arm assemblies includes a rotating wheel and a swing arm mechanism, the swing arm mechanisms include a swinging arm, and a connecting member rotatably connected to the swinging arm via a second rotational shaft, the connecting arm is provided with a slot matched with the second rotational shaft, the slot is disposed in a direction parallel to the axis of the second rotational shaft, and the length extending direction of the slot is disposed in parallel to the extending direction of the guide pin.

An apparatus for minimally-invasive, including non-invasive, prevention and/or treatment of hydrocephalus and method for use of the same are disclosed. In one embodiment of the apparatus, a housing is sized for superjacent contact with a skull having a fontanel. Within the housing, a compartment includes a pressure applicator, such as a fluid-filled bladder, under the control of a pressure regulator. The pressure applicator is configured to selectively apply an external pressure to the fontanel. The compartment includes a pressure sensor configured to measure intracranial pulse pressure of the fontanel. Further, in one embodiment, the apparatus can cause pulse pressure modulation by adjusting the intracranial pulse pressure via the pressure applicator. This enables a non-invasive measurement of the pulse pressure and modulation thereof in infants, for example.
