Stimulation devices are disclosed. An example stimulation device includes a chamber which has a flexible wall portion. A drive unit of the stimulation device is in physical communication with the flexible wall portion so as to cause deflections of the flexible wall portion in opposing directions, thereby resulting in a changing volume of the chamber. The changing volume of the chamber results in modulated positive and negative pressures with respect to a reference pressure. An opening of the stimulation device is for applying the modulated positive and negative pressures to a body part. The stimulation device includes a control device for controlling the drive unit.

The present disclosure relates to a device including electrostatic brakes providing haptic kinaesthetic feedback to a user in e.g. assistive, rehabilitation or virtual reality scenarios, as well as tele-manipulation.

Embodiments of the present disclosure are directed to systems, devices, and methods of inducing physical effects in tissue, such as dermis, adipose, musculoskeletal, vascular, hepatic tissue, using unfocused or planar, non-cavitating acoustic shock waves. The physical effects include disruption of fibrous extracellular matrix of the targeted tissues. Embodiments of the present disclosure include applying rapid acoustic pulses (e.g., shock waves) to cause a breakdown in the fibrous extracellular matrix to reduce the appearance of cellulite or scars in a treatment area. Such unfocused or planar, non-cavitating acoustic shock waves may induce a tissue reaction, such as reduction of fibrosis, induction of angiogenesis, or lymphangiogenesis.

An actuator array includes an elongated base and a plurality of pneumatic actuator elements removably attached to the base. The base is made of a pliant and inextensible material. The actuator elements are configured to be inflated and interfere with each other in use to generate a bending motion supported by the base. At least one parameter associated with the actuator elements is selected to control a three-dimensional (3-D) profile of the bending motion.

An air compression device includes a bottom shell, a top shell arranged at a top portion of the bottom shell, and a solenoid valve assembly. A handle hole is on one side of the top shell. The solenoid valve assembly includes solenoid valves. A row of control air passages is disposed on a top portion of the solenoid valve air distribution bracket. The row of control air passages includes first control air passages disposed on a middle portion of the row of control air passages and second control air passages on two sides of the row of control air passages. The first control air passages are communicated with a first row of working air passage. The second control air passages are communicated with a second row of working air passages. The solenoid valves are disposed on the row of control air passages.

A pneumatic physiotherapy apparatus with a unique structure comprising a wrap and an operating unit: wherein a wrap includes at least an outer wrap, an inner component housing, and an inner air bladder set; the operating unit is fixed to the outer wrap; the operating unit is also connected to the inner component housing; and the inner component housing is hidden inside the wrap. In addition, the apparatus can also have the operating unit operate an inflation motor and an integrated control board. The apparatus uses an inner air bladder set wherein each air bladder is inflatable. The apparatus can also contain a solenoid valve and a pressure detection valve. This design hides bulky components and eliminates connecting brackets. Therefore, this apparatus is a unique structure that allows a user to experience the extraordinary beauty of pneumatic physiotherapy apparatuses.

CPR devices with a combustion unit and associated methods are disclosed. According to an aspect, a CPR device includes a first mechanism configured to attach to a torso of a patient for providing chest compressions to the patient. The CPR device also includes a second mechanism comprising a piston and a shaft. The piston is movable within the shaft and is attached to the mechanism for movement of the mechanism when the piston moves within the shaft. Further, the CPR device includes a combustion unit operatively connected to the piston for powering the movement of the piston within the shaft. The combustion unit comprising a chamber configured to receive propellant. The combustion unit is configured to controllably ignite the propellant in the chamber for powering the movement of the piston.

Disclosed is an exoskeleton wearable device configured to push a condyle out from a glenoid structure of a skull made of two bellows shaped actuators each having an elliptical cross-section; an upper part configured to be fixed on a forehead of a patient and provide a base for the two bellows shaped actuators; and a lower part configured to be fixed on a mandible of the patient and substantially static to the mandible but moveable in a horizontal plane and a vertical plane with respect to the upper part.

A back therapy apparatus for vertebral massage includes a plurality of manipulating assemblies. The apparatus is adjustable and arranged to engage a spine at multiple locations over an extended length at vertebral areas between a spinous process and a transverse process on either side of a spine. A drive system is adapted to drive multiple manipulating assemblies simultaneously and independently.

The movement inducing device includes a plurality of air bags, each being provided with a contacting portion configured to contact with a user and induce a movement of an intended skeletal muscle of the user; a drive mechanism configured to expand and compress the air bags by adjusting supply and discharge of air to and from each air bag and a control unit provided with a drive control unit configured to control driving of the drive mechanism to make the intended skeletal muscle of the user perform at least one of an isotonic muscle activity, an isometric muscle activity and an isokinetic muscle activity.
