A body weight unloading apparatus according to an aspect of the present invention includes a first actuator, a second actuator, a first support member, a second support member, a sensor for measuring the imbalance between floor reaction forces respectively acting on the legs of a user, and a control device for controlling operations of the actuators. One end of the support members is respectively connected to the actuators, and the other end of the support members is fitted to the user such that unloading forces that are supplied by the actuators respectively act on the legs of the user. The control device controls the actuators so as to respectively generate unloading forces determined according to the imbalance between the floor reaction forces.

A sprocket transmission mechanism of a massage device contains: a driven box, a pair of hollow holders, and two bendable chains. The driven box is driven by two drive shafts of a motor beside the driven box. The pair of hollow holders are rotatably connected with the two drive shafts respectively and have two grooves, and the pair of hollow holders are connected inside two inner sides of a chair or a bed respectively. The two bendable chains are accommodated in the two grooves individually. The two drive shafts have four sprockets fitted on two sides thereof individually, and two driven sprockets are rotatably connected between the two sides of the two shafts respectively, such that the two bendable chains are inserted into the pair of hollow holders to mesh with and to drive the four sprockets and the two driven sprockets to rotate individually.

The present disclosure relates to a prostate massage apparatus including a cushion part on which a user is able to sit, a reciprocating horizontal movement part installed to be horizontally movable along both sides inside the cushion part, an acupressure part installed to be movable upward and downward at an upper end of the reciprocating horizontal movement part and configured to move upward to a pressing position due to an elastic force of an elastic member, and a driving part mechanically connected to the reciprocating horizontal movement part by a power transmission member inside the cushion part and configured to, when driven to rotate, allow the reciprocating horizontal movement part to move back and forth along both sides.

A vibration therapy device that includes a housing that includes a handle portion, a head portion and a module seat defined on the head portion, 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 reciprocate in response to activation of the motor, and a therapy module removably secured to the module seat. The distal end of the push rod assembly is configured to removably receive a reciprocating attachment thereon. The therapy module at least partially surrounds the distal end of the push rod assembly.

A roller massage table has a leg under each comer, a leg disposed under the center of the table, and a roller mechanism mounted within the center of the table. The roller mechanism includes a spring-loaded wheel and is slidingly mounted to a pair rails on the underside of the table enabling the roller mechanism to move up and down along a single axis.

A vibration therapy device that includes a housing that includes a handle portion, a head portion and a module seat defined on the head portion, 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 reciprocate in response to activation of the motor, and a therapy module removably secured to the module seat. The distal end of the push rod assembly is configured to removably receive a reciprocating attachment thereon. The therapy module at least partially surrounds the distal end of the push rod assembly.

An apparatus for treating or preventing venous deficiency, thrombus development, orthostatic intolerance, lymphedema, and/or edema comprising a sleeve wearable on a limb of a user; an upper bracket and a lower bracket releasably couplable to the limb; an actuator coupled to one of the upper or lower brackets; a shaft coupled to the actuator and the other of the upper or lower brackets; a plurality of cams fixedly coupled to, and longitudinally spaced along, the shaft; and a respective plurality of flexible elements each coupled to one of the plurality of cams and to the sleeve. Rotational motion of the actuator about an axis of rotation causes the plurality of cams, via the respective plurality of flexible elements, to induce a peristaltic pressure wave in the limb.

The invention refers to a system of a plurality of pendulums with controlled oscillation and trajectory which delivers the oscillatory movement in the upper part of its geometry, where it is recovered and transferred to the desired object, be it a chair, a crib or a bed, and since this motion is transferred or projected from below, does not need suspension points external to the system or to the object for it to experience a stable and safe oscillatory motion.

A medical traction system provides an elongate track having a slide with a handle so that tensioning of the strap can be performed directly on the slide with improved tension sensitivity. The slide provides a cam mechanism with low back-travel automatically locking the slide when tension is released permitting one-handed operation.

A massage module according to an embodiment includes: a support plate including a circular opening therein; a massage body provided in the circular opening of the support plate; and a rotating mechanism for rotating the massage body relative to the support plate, wherein the massage body includes: a massage unit which provides a massage to a user through mechanical stimulation; a rotating plate provided to be rotatably moved relative to the support plate by the rotating mechanism; and a moving mechanism provided in the rotating plate to move the massage unit in a direction perpendicular to the rotation plane of the rotating plate. The rotating plate includes a through-opening through which the moving mechanism can pass, and the moving mechanism can pass through the through-opening to move the massage unit between a first position and a second position.
