The present invention discloses a soft knee exoskeleton driven by a negative-pressure linear actuator, including: an exoskeleton controller, a left leg knee joint soft actuator, a right leg knee joint soft actuator and the like. The soft knee exoskeleton mainly uses a miniature vacuum negative pressure pump as an air pressure power source. A DSP embedded control system performs real-time processing on the data, such as a muscle force, a knee joint angle and a human-machine interaction force, detected by a sensing system, estimates a human-machine cooperation state, and performs real-time control on the switching of the negative pressure flow and an air channel of the miniature vacuum negative pressure pump.

A percussion massager comprises a motor, a reciprocating assembly, a mallet, a power source, a housing, and a fixing frame. The motor, the reciprocating assembly and the power source are operably arranged in the housing. The motor comprises a main body and a first rotary shaft. Part of the mallet is not located in the housing. The first rotary shaft of the motor is operably mechanically connected with the reciprocating assembly. The reciprocating assembly is mechanically connected with the mallet. The fixing frame is installed in the housing. The main body of the motor and the reciprocating assembly are installed on the fixing frame. The main body of the motor and the reciprocating assembly are installed in the housing via the fixing frame only. When the motor is electrically connected with the power source, it rotates to drive the reciprocating assembly to reciprocate under the driving of the power source, thereby driving the mallet to make reciprocating linear motion for repeated striking.

An apparatus and method for applying caresses and massages, comprising an apparatus composed of a fixed lower section, which acts as a base, contains the lifting mechanisms, and houses a movable upper section, with a housing that accommodates the rest of the components of the device; a SCARA-type deployable robotic arm housed in the upper section and composed by a plurality of staggered parallel links and articulated at their ends by a power transmission mechanism comprised by motors with belts placed on pulleys coupled to concentric hollow shafts. The upper section is placed on a sliding and rotary platform that supports and guides it on the vertical axis through a vertical lead screw lifting mechanism, also allowing it to rotate on its own axis. The apparatus performs the movements by implementing a method of preset caress and massage patterns assisted by artificial intelligence and guided by several sensors.

Techniques and devices for extending a piston and/or compression unit, for example connected to a medical device such as a mechanical CPR device, to accommodate different sized patients, are described herein. In some cases, a piston of a mechanical CPR device may include an inner piston at least partially slidable into an external piston sleeve. In one aspect, some aspects, the piston includes sleeves which can move relative to each other to extend the piston. In additional aspects, the compression mechanism may also extend downward toward the patient. In all aspects, the change in length of the piston may be detected and used to modify movement of the piston, for example to more safely perform mechanical CPR.

This massage head includes a housing, having two active members emerging from the lower surface thereof, having its free lower edge, opposite to the housing, intended to be in contact with a patient's skin. One at least of said active members is formed of a flap hinged within the housing and capable of being pivoted to bring the lower edges of said active members closer to each other or draw them away from each other, the relative displacement of said at least one flap being ensured by means of a rotary cam formed within the housing, the rotation axis of the cam being oriented substantially parallel to the displacement direction of said at least one flap. The cam includes at least one cam track formed on its periphery, intended to cooperate with the flap support(s), having one or their ends hinged in the housing.

An electromechanical device for male sexual stimulation that uses a reciprocal linear motion similar to sexual intercourse, and wherein the penis remains fully inserted during use. The reciprocal linear motion is generated by a small motor which drives a screw and nut mechanism, to which a bracket and gripper is attached. Inserted into the gripper is a flexible sleeve. A penis may be inserted into the device inside the flexible sleeve. The movement of the gripper and sleeve against the penis provides pressure and motion against the penis inside the sleeve in a manner similar to sexual intercourse. The speed, pattern, and location of the motion can be controlled by the user through controls on the outside of the device.

A vertical rhythm machine includes a base, a driving mechanism, an eccentric mechanism, two transmitting mechanisms and a housing. The eccentric mechanism is assembled with the driving mechanism. Each of the transmitting mechanisms includes a transmitting plate, a linking shaft, a first transmitting assembly and a second transmitting assembly. The transmitting plate is arranged on the eccentric mechanism. The linking shaft passes through the transmitting plate. The first transmitting assembly and the second transmitting assembly are pivoted on the linking shaft. The housing is disposed on the first transmitting assembly and the second transmitting assembly. The eccentric mechanism is driven by the driving mechanism to drive the transmitting plate. The transmitting plate drives the linking shaft to move reciprocally. The first transmitting assembly and the second transmitting assembly are linked with the linking shaft to drive the housing to move reciprocally.

A mirror therapy device includes a first positioning assembly, a second positioning assembly and a transmission assembly connecting the first and second positioning assemblies. The first and second positioning assemblies are arranged in opposition to each other in such a manner that both are able to reciprocate. The first positioning assembly is configured for positioning of a healthy limb of a patient, and the second positioning assembly is configured for positioning of an affected limb of the patient. The transmission assembly is configured for power transmission between the first and second positioning assemblies so that the second positioning assembly moves in synchronization with the first positioning assembly under the action of the transmission assembly. A mirror therapy system includes the mirror therapy device and a display device. The mirror therapy system enables the healthy limb to drive movement of the affected limb to allow the affected limb to repeat the same movements as the healthy limb, thus establishing neural connections for synchronous vision, motor perception and proprioception of the patient's healthy and affected sides and better stimulating nerve recovery of the patient.

Examples of a device for guiding and detecting a motion of a target joints and a motion assistance system such motion guiding devices are described. The motion guiding and detecting device comprises a motion generator and a motion transfer and target interfacing unit to transfer the motion generated by the motion generator to the target joint. The system further includes a motion detection and feedback unit that interfaces with the target, and a controller that interfaces with both the feedback unit and the motion generator to control and coordinate the motion of the motion generator and the target joint.

The scratch panel is a wall-mounting panel to relieve itching in particularly difficult to reach locations, such as the back. It utilizes artificial turf and sand paper like textured surfaces upon which the body may be scratched. Since the panel is wall-mounted, no hands are necessary to relieve bothersome itches. The panel holds adjustable rollers that stretch the artificial turf and allow recycling of the surface. The adjustable rollers allow the user to use different parts of the turf and replace said turf when necessary. The disclosed device includes a scrollable abrasive material stretched across a first scroll and a second scroll wherein the scrolls each lock to fix the scrollable abrasive material in a fixed relation thereto. A holder receives the scrolls in a rotating relation and provides a grip for a user and defines mounting holes to a wall or a piece of furniture.
