A percussive massage device that includes a housing, an electrical source, a motor positioned in the housing, a switch for activating the motor, and a push rod assembly operatively connected to the motor and configured to reciprocate in response to activation of the motor. The housing includes first, second and third handle portions that cooperate to define a handle opening, wherein the first handle portion defines a first axis, the second handle portion defines a second axis and the third handle portion defines a third axis, and wherein the first, second and third axes cooperate to form a triangle.

A percussive therapy device that includes a housing, an electrical source, a motor positioned in the housing, a switch for activating the motor, and a push rod assembly operatively connected to the motor and configured to reciprocate in response to activation of the motor. The percussive therapy device includes at least one of a thermal sensor, a heart rate monitor or a heated massage member.

A motorized tensioning mechanism for orthotic devices, such as a knee brace, wherein the controls for the motorized tensioning mechanism may be manual, automatic, or a hybrid of both. Sensors associated with the orthotic device may inform the user regarding tension or other aspects of the device, and, in cases, may automatically adjust tension in the motorized tensioning mechanism.

A walking assistant robot, comprising a main frame body (1), a foot walking mechanism for alternating walking, an auxiliary device (2) and a control device; the walking mechanism, the auxiliary device (2) and the control device are all disposed on the main frame body (1); the control device is connected with the walking mechanism; the auxiliary device (2) includes auxiliary feet (201), and the auxiliary feet (201) are disposed in front of and/or behind the walking mechanism along the walking direction. The foot walking mechanism is used to realize the basic function of the robot walking forward; auxiliary feet (201) are disposed in the walking direction such that the walking mechanism still has, at the moment of foot alternation, multiple supporting points in contact with the ground. Therefore, the mechanism is slip-and-fall-resistant, stable and reliable and guarantees the user safety.

A percussive therapy device that includes a housing, an electrical source, a motor positioned in the housing, a switch for activating the motor, a push rod assembly operatively connected to the motor and configured to provide reciprocating motion in response to activation of the motor, and a massage attachment secured to a distal end of the push rod assembly. The reciprocating motion of the push rod assembly has a user-adjustable amplitude.

A massage chair capable of massaging the front body region is proposed. In the massage chair, one end is rotatably coupled to the backrest part and the backrest part for supporting the user's back, and includes a front massage part for massaging the user's abdomen or chest. According to the present configuration, there is proposed a massage chair capable of performing massage even in a front body region of a person to be treated, such as a chest or an abdomen.

A percussive therapy device that includes a housing, an electrical source, a motor positioned in the housing, a switch for activating the motor, and a push rod assembly operatively connected to the motor and configured to reciprocate in response to activation of the motor. The housing includes first, second and third handle portions and a head portion that cooperate to define a handle opening. The first handle portion defines a first axis, the second handle portion defines a second axis and the third handle portion defines a third axis and the first, second and third axes cooperate to form a triangle. The motor is positioned in the head portion of the housing, and at least a portion of the push rod assembly extends outside of the head portion.

The apparatus is configured for applying chest compressions to a patient to apply CPR. The apparatus includes a housing configured to mount the apparatus to the patient, a unidirectional motor, and a plunger connected to the unidirectional motor, the plunger configured to apply the chest compressions to the patient when the motor is operated. The apparatus may include a device configured to control a compression distance of compressions. The apparatus is simpler, lighter and eliminates complicated motor control required in prior devices.
