In a piston sucking-type massager disclosed in the present invention, a massage port of a straight-cylinder piston chamber is in contact with the human skin and then closed, a push-pull driving device drives a push-pull member to reciprocate and translate linearly, and a piston follows the action of the push-pull member to reciprocate and translate linearly in the straight-cylinder piston chamber, so that positive and negative pressures are formed in a space between the manage port of the straight-cylinder piston chamber and one end surface of the piston, for sucking massage.

A decompression device and a method using the decompression device are provided. The device includes a support structure having a longitudinal brace, and a cross brace that may be coupled to or part of the longitudinal brace. A harness may be coupled to the cross brace, and the harness may have a traction surface. An adjustable fastener may control the harness length therein controlling the distance between the traction surface and the first cross brace. The base positioned on a surface or structure, and portions of the harness positioned around the body of a user, such as under the arms and around the back. The user may manipulate the adjustable fastener to position portions of the harness a desired distance from the cross brace. The user may then leans forwards tilting the decompression device and the harness will provide lift, and therefore decompression, to the back of the body of a user.

A foot stretching device for stretching the structures of a foot comprises a base for receiving a rear portion of the foot to be stretched and a toe plate for receiving the toes of the foot to be stretched. The toe plate is disposed on and pivotable relative to the base. The device further comprises a member coupled to and/or configured to engage the toe plate, such that a tensile force applied to the member by a user pivots the toe plate relative to the base. and thus the user's toes relative to the rear portion of their foot. This action causes the toes to move into a more extended position thus producing a stretch in the tissues of the foot, in particular the musculature associated with the planar fascia.

A mat transmission structure includes a first body, multiple first operation units, and a power unit. The first body is provided with a first recess and multiple first pivot portions. Each of the first operation units is pivotally mounted on each of the first pivot portions. Each of the first operation units includes a rod, multiple first operation members, and a first driving member. The rod is provided with a first fitting portion, two first pivoting sections, and a first mounting portion. Each of the first operation members is provided with a first surface and a second fitting portion. The first driving member is mounted on the first mounting portion. The power unit drives the first driving member of each of the first operation units such that each of the first operation units is rotated in the first recess.

A walking assistance system includes a walking assistance apparatus attached to a leg of a user and a notification unit configured to notify the user of a predetermined state in the walking assistance apparatus. The walking assistance apparatus includes a flexion damper that applies a resisting force in a bending direction of a knee joint of a leg, a sensor that detects a switching timing in a gait cycle of the user, a control unit that switches the mode of the flexion damper in accordance with a switching timing, a detection unit that detects a predetermined state, and a transmission unit. The notification unit includes a vibration stimulation module that applies vibrations or electrical stimulation to a non-paralyzed area of the user's body and a reception unit.

A hand-held massage gun and conversion mechanism thereof are disclosed. The hand-held massage gun includes a massage gun body and a conversion mechanism. The massage gun body includes an output rod. The conversion mechanism includes a hollow shell, a movable block and return springs. The hollow shell is detachably connected to the massage gun body, and two ends of the hollow shell are provided with an opening and a long hole. The movable block is accommodated in the hollow shell. The movable block has an inclined surface, an abutting portion and a linkage rod inserted in the long hole. The output rod is inserted in the opening and abutted against the inclined surface. The return springs are elastically supported between the hollow shell and the abutting portion.

A massage system for a seat of a vehicle includes a drive motor, a sliding member having a hollow pillar shape, a first end of the sliding member being blocked by a plate member and a second end of the sliding member being opened, a housing member having a hollow pillar shape, a first end of the housing member being blocked by a partition and a second end of the housing member being opened, and a drive gear module operably connected to the drive motor, wherein at least one roller member is extended toward the housing member at an edge of the plate member, and at least one cam protruding toward the sliding member is formed at a circumference of the partition, wherein a cam profile is formed at a surface of the cam.

A progressive sequencing lactating breast milk extraction apparatus comprising a series of compression segments arranged forming a conical shape extending between a wider chest end and a narrower extracted milk collection end, at least one vibration generating apparatus in vibrational communication with at least one compression segment of the series of compression segments; and an operational mechanism to contract and expand each compression segment. In use, the operational mechanism cycles each compression segment of the series of compression segments between a compressed state and a relaxed state and the cycles are provided sequentially from a rear of the progressive sequencing lactating breast milk extraction apparatus to the extracted milk collection end. The vibrational energy applied to the breast aids in flow of the milk through the breast.

A bodyweight unloading locomotive device includes a frame configured to support locomotive movement, and an unloading assembly carried by the frame. The unloading assembly includes a spring having a fixed end coupled to the frame and an opposed free end, a cam assembly mounted to the frame for rotational movement, a first tether extending from the free end of the spring to the cam assembly, and a second tether extending from the cam assembly to a load. The unloading assembly exerts an unloading force on the load with respect to the frame.

A handheld device for applying mechanical vibration to a body portion of an individual to treat a dry eye condition of the individual, includes: a housing; a member having a first portion accommodated in the housing, and a second portion that is moveable relative to the housing, wherein the second portion is for placement outside the individual, and is configured to oscillate to apply the mechanical vibration to the body portion, the member having an elongated configuration; and a motor in the housing, the motor configured to oscillate the member at an oscillation frequency sufficient to induce tear production when the second portion of the member is applied towards a surface of the body portion.
