Abstract: Disclosed herein is a foot protection device adapted to protect feet when training and playing fighting games. The device includes an exterior cover (100). The exterior cover has an opening (10), an anterior hole (20) and a posterior hole (30) provided on a sole portion (A), toe insert parts (40) provided on a toe portion (B) and having toe holes (45), and an ankle securing means (150) provided at an end of an ankle portion (C). The device protects a wearer's feet, and is in maximally close contact with the feet due to its elastic force, and is light in weight, thus providing a sensation similar to that of a barefoot state. Further, a part of the foot is exposed to the outside, thus preventing the wearer from sliding on the ground surface, and allowing free movement of the foot, therefore affording a high level of power and quickness.

Abstract: A valve geometry applicable to the end of condoms to permit re-use with the same partner, or to enable condoms to permit the transmission of semen and thus permit conception as a result of intercourse while retaining the epidemiologically protective effect of barrier type infection control.

Abstract: Devices and methods for maintaining an open airway are described. Systems and methods are described for maintaining an opening of an airway by application of force to a patient's tissues in one of inferior, anterior, and lateral directions.

Abstract: A male chastity system comprises a housing and a partial ring configured for placement behind the scrotum of the user. The partial ring contains a gap. A bridge bridges the gap by attaching to the partial ring at first and second attachment points. The bridge comprises a rear portion and a front portion, and the partial ring and the bridge collectively form a ring. Guide pins extend at least partially through the rear bridge portion, attachment points, front bridge portion, and housing. A locking pin extends through the bridge and housing, a spacer on the locking pin spacing the housing from the ring, and a lock is applied to the locking pin.

Abstract: Methods and apparatus provide for: coupling an elongate guide substantially at a first end to at least one vertebral body of a spinal column of a patient; and extending a second end of the guide to a structure of the patient spaced in an anterior direction away from the at least one vertebral body towards an entry incision.

Abstract: Devices and methods are disclosed for achieving control and stabilization of bone fractures in mammals, most specifically humans. Stabilization and traction is often required to support fractured bones of the arms or legs. The devices and methods disclosed herein are especially useful in the emergency or military setting. The devices utilize a collapsible frame or inflatable member that may be expanded and locked into position. The frame or inflatable member is fabricated primarily from polymeric materials with low radiodensity. The limb contact regions are adjustable to fit a wide variety of limb sizes and fracture locations. The traction applied by the splint is adjustable, controllable and measurable. The traction splint is sufficiently compact that it will fit in a compartment of most ambulances and emergency rescue vehicles, thus making it more available for use than standard traction splints in use today. The traction splint is either a separate device or integrated into a backboard.

Abstract: A cast or support for use in limiting movement of the anatomy to promote healing of an injured body part includes initially flexible and subsequently rigid double-knit material, or other casting blanks. There is a water-hardenable material impregnated into the casting blank. Certain areas of the blank have significantly reduced or no hardenable material. This construction may provide at least one hinge line which extends substantially across the double-knit material or other casting blank where the upper and lower layers are held in engagement with each other. The cast or support may be folded open along the hinge line to permit washing, inspection, or treatment of the portion of the anatomy to which the cast or support is applied or as one step in the preparation of a mold of a portion of the anatomy. More than one hinge line may be provided. Overlapping edges of the blank may also be of reduced thickness and with reduced hardening material to provide a smooth overlap to secure the cast or support in place.

Abstract: The present invention pertains to an articulating joint that is disengageable between two modes of operation: unidirectional movement of the joint or bi-directional movement of the joint, with features that allow the mode to be automatically switched as required. When fully locked, the joint inhibits joint flexion while allowing joint extension. When actuated, a locking mechanism is disengaged to allow both uninhibited flexion and extension of the joint.

Abstract: A whiplash restrainer for use by riders in vehicles, generally in conjunction with safety belts. A helmet-like device is secured, with reasonable freedom of motion of the rider's head, to a shock absorber by a joint device. The shock absorber is removeably secured to the vehicle seat back.

Abstract: An adjustable neck brace worn at a human neck for fixing a cervical vertebra includes a cover panel and an adjusting device fixed onto a surface of the cover panel, and the adjusting device includes an adjusting rod, a limit member and an adjusting knob disposed on a surface corresponding to the adjusting rod, and an end of the limit member includes a bracket, and the adjusting knob links an adjusting gear installed at the adjusting rod, and an end of the adjusting rod includes a height adjusting plate having a supporting portion for supporting a chin. With the foregoing technical measures, the invention features a secured and stable structure to maximize the effects of medical treatment and physical therapy. The height of the supporting portion can be adjusted to provide users a feedback about a definite feel of the adjustment through the bracket.
