A therapeutic support apparatus comprises multiple layers of foam having different densities and memories. The support apparatus comfortably supports the weight of a user while minimizing pressure points between the user and the support apparatus. Each foam layer has a unique density and memory based upon the type of tissue the layer is intended to support. A relatively low-memory outer foam layer made from latex non-viscoelastic foam substantially supports skin and subcutaneous tissue. A relatively high-density and medium-memory intermediate layer made from polyurethane foam supports muscle tissue. A relatively high-density and high-high memory core layer made from polyurethane foam supports the spine. In combination, these layers minimize hyperextension and promote blood circulation and comfort while the support apparatus is used by a user positioned in a supine, recumbent, or sideways-lying position.

This invention can be used in three different ways for patients who are lying down in bed or on the operating table. First it facilitates the endotracheal intubation, secondly it facilitates the spontaneous breathing of obese patients and thirdly it assists the spontaneous inspiration and expiration in a non-invasive way. This invention device is positioned under the patient before he is asleep without disturbing him. It allows a gradual elevation of the lower and or upper thorax, a gradual elevation of the head giving a flexion of the neck and a gradual hyperextension of the head. After intubation the position is returned to normal without need for removing the invention device. This invention elevates the spinal column and therefore the thorax is no more compressed and the ribs can move free. Inspiration requires less force and the patient can be breathing easier even when lying down. In this invention the spinal column elevation can also be inflated in a synchronized way with the respiration of the patient. During inspiration the spinal column is elevated, facilitating the inspiration. During expiration the elevation is lowered, facilitating the expiration. The work of breathing is reduced for the patient resulting in larger minute volume ventilation or less oxygen consumption.

A posture correction brace for a person has a tightening mechanism that allows a user to pull a cord to pull down on the back of a pair of shoulder straps, thereby pulling the shoulders back to correct the person's posture. The front ends of the shoulder straps are typically also attached to the back of the wearer, to help the posture correction brace pull the shoulders back as the shoulder straps tighten.

Example embodiments of the brace assembly utilize an elastic cross strap attached to mounting facilities about a joint to provide progressive resistance to the extension, flexion or other movement of body parts about the joint. In some embodiments for a knee joint, the brace assembly provides a progressive resisting force to resist hyperextension of the knee. Some embodiments of the assembly may be able to accommodate different joints, different size wearer's of the assembly and different tension settings such as for athletes during competition. Some embodiments of the brace assembly may be used bilaterally and can be made without metal bracing to comply with the requirements of some sports.

A bone fixation system and method are provided. The system includes a dual prong pin and a bone screw.

Fracture of other long bones of the hand, foot or elsewhere may be managed with this bone fixation system.

A protective pad including a rigid shell bounded by a perimeter and a gasket engaging the perimeter so that forces applied to the shell are dissipated through the gasket before transferring to a wearer of the protective pad. The rigid shell cooperates with the gasket to provide a trampoline effect or two way spring. This effectively absorbs shock from forces generated by the opponent, so that the wearer and a colliding opponent both encounter reduced forces. The shell can bow outwardly to form a cavity above the wearer when the gasket is placed adjacent the wearer, which can prevent the rigid shell from bottoming out against the wearer upon impact. The protective pad can be implemented in a thumb protector including a stopper disposed between adjacent rigid shells covering proximal and distal portions of a digit. The stopper can engage the shells and effectively prevent hyperextension of the digit.

A glove with a support system is disclosed. The support system comprises a number of individual support sections, each of which is comprised of a number of arcuate support segments that encircle or surround a portion of a finger and allow forward flextural movement while helping to protect the finger. For example, the support system can help reduce hyperextension of the finger, the possibility of the finger jamming, and help to protect the finger from lateral or side impacts.

A full-body exercise machine. The exercise machine includes a first mechanism that enables a user to selectively apply positive resistance to a first leg and/or a second leg independently or simultaneously. The resistance is applied during pushing and/or pulling motions as the first leg and/or the second leg move in opposite or similar directions relative to the second leg and/or first leg, respectively. A second mechanism selectively applies positive resistance to a first arm and/or a second arm independently or simultaneously, in different or similar directions. The resistance is applied during pushing and/or pulling motions. A third mechanism facilitates abdominal crunches, leg tucks, and/or back hyperextensions while exercising the legs and the arms via the first and second mechanisms. In a specific embodiment, the third mechanism includes a seatback linked to the first and/or second mechanisms so that actuation of the first or second mechanisms causes actuation of the seatback. Mechanical links are connected between the first mechanism, the second mechanism, and the third mechanism via swivel connectors. A stable seat accommodates the user, which facilitates performing simultaneous tasks, such as reading or watching television.

An ankle-foot orthotic device is designed to closely simulate the natural movement of a lower extremity throughout a proper walking gait cycle. The orthotic device includes upper and lower support members that are pivotally coupled by opposing dorsiflexion assist members. The lower support member includes a rigid, unitary cup for receiving the heel and ankle portions of the lower extremity. The cup is shaped to include a continuous slot that allows for at least 5 degrees of compression upon initial heel strike and thereby promotes a smooth, decelerating heel roll. The lower support member additionally includes a rigid footplate on which is mounted a flexible overlay, the overlay extending beyond the footplate in the medial aspect to promote proper pronation into midstance. A compressible stop is mounted on the lower support member and selectively contacts the upper support member to prevent hyperextension of the lower extremity.

An orthotic protective device collectively including a base unit connected to a metacarpal unit by a hinge system designed to protect and prevent hyperextension and hyperflexion movements of the metacarpal, carpal, radius and ulna regions. The base unit and metacarpal unit includes a longitudinal support member and a casing, respectively, lined with at least one pad having a tongue. At least one releasable fastener is mated to the support member and casing and extends to the tongue of the pad.

Apertures of the base unit are mated and connected to apertures of the hinge system which form an articulated joint allowing the hinge system to move in an upward manner allowing for natural extension of the user's wrist and in a downward fashion for unlimited flexion motion. The base unit and the hinge system may both have at least one stop formed thereon; and as these stops come into contact with one another, it limits the flexion, extension and radial-ulnar deviation. Further, an aperture of the metacarpal unit is mated and fastened to an aperture in the hinge system by a swivel joint which allows for lateral movement of the user's wrist.

A table assembly for a patient transfer device has an upper table with side plates that are differentially extended at the ends, and valve control for pneumatic tubing integrated with retraction of the side plates. During patient delivery only the delivery side plate is raised, to avoid catching linens in the nip formed between upper and lower belts. A slide assembly supporting the table assembly includes a fixed plate, an intermediate plate, and a full-motion plate which extend by means of rack-and-pinion drives. Each plate is symmetrical, and pinions are symmetrically located on opposite sides of the fixed or intermediate plate to allow hyperextension to either the left or right. Improved steerage for the device is provided by two centerline wheels which counter-rotate from a straight position to a turning position and further to a lateral position wherein the wheels are orthogonal to the longitudinal centerline of the device.

A prosthetic hard socket has a modified curvature and/or shape, which eliminates or de-emphasizes the patellar bar to eliminate or reduce pressure on the wearer's patellar tendon, and, instead, enhances support of the anterior tibial condyle and/or tibial tubercle. Thus, the preferred socket is designed with the patellar tendon preferably not being weight-bearing. The preferred curvature and/or shape comprises a lowered socket edge and/or a gap in the socket wall in the region of the patellar tendon, so that the hard structure of the socket does not directly support or press upon the patellar tendon. The invented socket may include inwardly-protruding regions on each side of the lowered edge/gap, for helping to “capture” or otherwise press on a portion of the tibia for improved rotational control. This combination of shapes and curvatures provides for improved rotational control, comfort, and range of motion including even full extension or hyperextension. A flexible and/or cushioning member may be placed in the gap/trough (that is caused by the lowered edge or removed wall portion), for example, a fabric, leather, rubber, or other member may be attached to the socket to across a V-shaped trough of the lowered edge of the hard socket.
