Uterine massage belts and related methods are generally described. In some embodiments, a massage belt may be configured to compress a uterus between two force-applying components to induce uterine contraction and reduce the risk of postpartum hemorrhage. The belt may include at least one roller configured to push at least a portion of the uterus (e.g., the uterine fundus) in an inferior direction. The belt may be used with at least one inflatable body to push at least a portion of the uterus in a superior direction. The uterus positioned between the opposing forces may be urged to contract and increase its muscle tone to avoid severe postpartum complications. In some embodiments, the inflatable body may be part of the belt and may be positioned proximal to the pubic bone of the patient. In other embodiments, the inflatable body may be separate from the belt and positioned inside the vagina.

A portable exercise device with a cylindrical and elongated main shaft and a plurality of central components that fit over the main shaft. Both ends of the main shaft are releasably attached handles. Each of the handles comprises a grip section that is cylindrical in shape and overlies a handle support. The grip section of each of the handles is releasably attached to the handle support, and the handle supports are releasably attached to the main shaft. Longitudinal axes of the main shaft and handles are collinear. Each of the handles comprises an attachment member that extends from a distal end of the handle and forms an arc. An inner circumference of the attachment member is circular except for a flat portion that is equal in width to the flat portion of the handle support. The handle attachment members are configured to releasably attach to the handle supports.

A massage device, including at least two massage elements and at least one bearing element, which is arranged between the massage elements, wherein the bearing element is designed in such a way that the massage elements can rotate independently with at least two rotational degrees of freedom per massage element, wherein the massage elements are surrounded by a tensioning element, which substantially defines the spatial position of the massage elements, wherein the bearing element includes bearing balls, which are arranged circularly, and wherein the bearing balls are arranged in a bearing cage.

The rotatable leg massage device has a base and a swinging arm. The swinging arm has a massaging end and a swinging end, the massaging end provided with a respective massaging roller on two sides. A second motor is disposed inside of the massage end and configured to rotate the two massaging rollers. The swinging end is disposed in front of the assembling base, and both sides of the swinging end are respectively provided with a swinging gear. A central aperture of each swinging gear is aligned with the through apertures of the assembling base and a shaft passing through all four apertures, the two swinging gears engages the two driving gears of the first motor, and the first motor is configured to drive the swinging arm to rotate around the base.

A modular self-massaging apparatus includes a framework and a ball assembly mounted to the framework. The ball assembly is modular and can be disassembled and reassembled in a variety of configurations. The apparatus is modular because the ball assembly and other ball assemblies can be applied to and carried in the apparatus at a variety of locations across the apparatus.

A back massaging device includes a seat back, a linear rack gear, a frame body, a main gear, a massage member, two motor assemblies and a control unit. The linear rack gear and the frame body are on the seat back. The main gear is pivoted at the frame body through a gear shaft. One of the motor assemblies is meshed with the main gear for rotating a massage protrusion of the massage member by an angle. Another motor assembly is meshed with the linear rack gear for driving the massage protrusion to vertically move. The control unit is electrically connected to the motor assemblies for calculating rotation angle values and vertical movements of the massage protrusion, and controlling the motor assemblies to operate synchronously to outline a trajectory pattern corresponding to one of trajectory scripts by the massage protrusion.

A mountable massage device is configured to have an adjustable length and be secured in a frame, such as a door frame, or other appropriate structure. In one disclosed embodiment, the device comprises a threaded rod, a center tube, first and second extension tubes, and first and second braces configured to support the device when secured in a frame. Handles are coupled to the center tube and allow a user to rotate the tube, thereby extending or retracting the extension tubes. This allows a user to match the length of the device to the width of a door frame. Massage pads are coupled to the center tube and may be used to massage a user's muscles.

A exercise roller device including a center roller portion provided with shaped end roller portions, and the center roller portion provided with a centered circumferential groove. A method of making the exercise roller device.

An exercise device that effectively targets and engages the abdominal and core muscles. The device includes a backrest, a first graspable pole, a second graspable pole, a height-adjustable headrest, and a rocking base. The rocking base acts as the supporting structure and includes a first rocker, a second rocker, and a bridge. The first rocker and the second rocker are connected to the bridge on either side. The backrest receives a user's back and is adjacently and pivotably mounted to the bridge, opposite the first rocker and the second rocker. The first graspable pole and the second graspable pole are positioned opposite to each other across the backrest. The first graspable pole and the second graspable pole are each laterally and rotatably mounted to the backrest. The height-adjustable headrest is centrally mounted in between the first graspable pole and the second graspable pole to receive the user's head.

A massager device includes a structure having a contact face and a handling face. A pair of notched rollers is on the contact face of the structure. The notched rollers freely rotates around intersecting axes. The notched rollers are attached to the structure by elastic suspensions. A gripping shape is on the handling face of the structure, opposite to the contact face. The gripping shape forms a cap wrapping the surface of the structure.
