A system for translating a constant traction load to an object such as a medical device or a patient includes a plurality of independently rotatable, coaxially aligned spools, each housing a constant force spring fixed at respective ends to the spool and to a rigid member, a plurality of flexible biasing members each coupled on their respective first ends to a spool and at least partially wound around the spool. A plurality of connectors are connected to the respective other ends of the biasing members, which may comprise wire rope. The connectors are configured to quickly couple to and decouple, directly or indirectly, from the object to which the traction load is being delivered. A guide provides a partial path for one or more of the biasing members to the object. A selected load may be applied by coupling one or more of the reversible couplers tensioned by the constant force springs to the object, without use of gravitational loading.

A shoulder immobilizer (20) includes a semi-rigid or rigid orthosis, in the form of an arm support (22), which supports the upper arm, elbow, forearm and wrist of a patient. A bolster (24) is positioned between the patient and the arm support (22). A body strap (26) extends around the patient and attaches to the arm support (22) and/or the bolster (24), holding the arm support and bolster in position against the body of the patient. In embodiments, the shoulder immobilizer (20) may utilize a shoulder strap (28), but such a shoulder strap is not necessary for shoulder immobilization of the patient.

A device that decompresses the lower spine while the wearer is seated or standing. The device includes two belt-shaped straps. The first strap circles the upper torso just below the breast line. The second strap circles the waist at or slightly above the normal belt line riding on the hip. In embodiments of the invention, the lower strap can be a normal belt. The straps can be equipped with pockets that are aligned along the upper edge of the upper strap and the lower edge of the lower strap designed to receive and hold flat splints. Typically, two rigid flat splints extend vertically between the straps centered laterally on the left and right sides of the torso. When the device is worn, it decompresses the lower spine when the person stands or sits.

Provided is an external fixator having a rotatable bone reduction frame for reduction of a fractured or deformed bone, which includes: a first frame through which the bone passes; a second frame through which the bone passes, the second frame being spaced apart from the first frame; a variable leg having both ends respectively connected to the first frame and the second frame and having a changeable length; and a rotating frame mounted to at least one frame of the first frame and the second frame to surround the bone entirely or partially, the rotating frame being rotatable based on at least one direction of a horizontal direction traversing the at least one frame and a vertical direction perpendicular to the horizontal direction as an axial direction.

Rate-dependent, elastically-deformable devices according to various embodiments can be stretched and recovered at low elongation rates. Yet they become stiff and resistive to stretching at high elongation rates. These device can be utilized in orthotics, braces, and circulation-enhancing compression garments for the prevention of injury, promotion of personal health, and/or enhancement in human performance. The rate-responsive properties of the devices are critical performance enablers, as they allow the devices to provide a unique balance of comfort and performance that cannot be achieved with conventional, passive straps, braces, and compression garments.

A buoyancy-based cervical traction system has a floatation and a head rest supported by the flotation system. The head rest is adapted to support a person's head above the neck and apply traction to the neck when the person is in a body of liquid. The system has a position adjustment system adapted to allow selective adjustment of the position at which the person's head rest will be relative to an upper surface of the liquid when the person and the cervical traction system are in the liquid, the person's head is supported by the head rest, and the cervical traction system and person are floating in the liquid at equilibrium.

The present disclosure describes an infant brace for treating an infant with a fractured clavicle. The infant brace includes a torso portion for receiving the donning infant's torso, and an arm portion for receiving the donning infant's arm on the side coinciding with the fractured clavicle. The infant brace is formed from an elastic netting material. The infant brace provides effective immobilization of the infant's affected upper arm while minimizing risks of over-heating or causing pressure sores.
