Abstract: An electrical having electric field producing electrodes either on the exterior or the interior surfaces, or both, of either an electrical cervical cap or an electrical diaphragm and supplying the electrodes with electric potential from miniaturized electrical cells embedded within an enlarged circular rim portion that surrounds the open mouth end of the device. Electrical is provided by the electrically excited electrodes and acts in conjunction with the cervical cap or diaphragm to prevent the migration of male sperm into the open end of the cervical canal of a female human being or other mammal. The electrical cervical cap or diaphragm device can be designed such that it is open at the apex and does not impede the free flow of menstrual and other fluid discharges through the cervical canal. It is fabricated with or covered by biologically inert material so that it can be retained in place in the cervical canal for indefinite periods as long as desired by the user for birth control purposes.

Abstract: The Motorized Walker is a device containing a frame assembly which a person walking can hold onto for support and help prevent a fall which might otherwise occur. This device need not be picked up between steps since an electric switch mechanism will activate a motor which will move the device the distance required between steps. This motorized feature permits support to be available at all times and the person using the device to walk faster than might otherwise be possible. This device also permits a person to walk where picking up a non-motorized walker might result in a fall since support is removed while the unit is being moved or where picking up a non-motorized walker is a formidable task.

Abstract: A multi-function hand splint for immobilizing a hand, wrist, and distal forearm of a user includes a sleeve made of a semi-rigid material. The sleeve includes an elongate shell of substantially C-shape with the opening of the C-shape located along the M-L plane of the forearm. This shell includes a dorsal shell portion and a volar shell portion. Extending from the dorsal shell portion is a dorsal hood having a metacarpal hood portion and a phalanx hood portion. The metacarpal hood portion forms a dorsiflexion angle of between 60.degree. to 80.degree. with the axis of the forearm so that a comfortable maximal dorsiflexion of the wrist is achieved. The metacarpal hood portion also forms a hood angle of between 75.degree. to 90.degree. with the phalanx hood portion. A palm arch supports extends from the volar shell portion in order to maintain the hand in the dorsal hood with the wrist in dorsiflexion and the metacarpal-phalangeal joints at an angle greater than about 90.degree. to 105.degree..

The pad has third and fourth flap opposed flap portions extending downwardly from the hemispherical portion, and a central portion connecting the third and fourth flap portions. The third and fourth flap portions are adapted to overlap upper portions over lower portions of the first and second flap portions, with the first and second flap portions facing each other, and with the third and fourth flap portions facing each other in the formed sheet.

Abstract: This invention relates to a kind of the structural improvement of the motion type solid water ball. The major improvement is to place permanent magnets respectively on the upper movable plate and the lower fixed plate in a form of combination arrangement. The center of lower fixed plate is fixed on the driving pole of the musical bell; and the upper movable plate is mounted on a movable plate with a rotuberant pillar standing in its center.

Abstract: A hinge element consists of a tube connector attached to the end of a tube, the end of the tube connector having a notched head portion. Pivotably attached to the notched head of the connector is a bracket element having a spherically shaped, notched end which engages the ends of a spring and a limiting wire. The limiting wire and spring are attached at their other ends to a cross bar and a second tube in which the hinge element and the first tube may slide coaxially. A hand grip is also disclosed which consists of a central grip portion with two cylindrical parallel holes having slits on the outside thereof. At the outer edges of the slits are ribs which, when the outer portions of the grip are tightened, focus the compressive forces generated by the tightening toward the tube portions, thereby creating a strong frictional hold. The hinge and grip configurations are found in a bitubular orthopedic crutch having three sections.

The adjustable elements applied to each crutch comprise a lever (1) pressed by hand (14) and fulcrumed (2) on a support (3) fastened along sleeve (4) of the crutch; a rod (5) controlling piston (6) of hydraulic damper (7), whose fluid (8) is made to pass through an opening of adjustable size to vary the pressure, being connected to the rod.

Abstract: A walking aid adapted for use either before or behind the invalid user and comprising a pair of tubular side sections spaced apart and connected by a transverse brace at one pair of opposed ends to form a four legged free standing walker frame. Each side section support and adjustably disposable upwardly extending hand support enable the latter to be best positioned for the user and for the use of the walker in either its fore of after the patient position.

Abstract: A reducible walking aid is disclosed that incorporates three bitubular sections in slidable engagement with one another in the preferred embodiment. The first and third sections are connected via a pair of elastic cables attached to slidable, bidirectional hinge elements anchored to the near ends of the first and third sections, with the cables running through the tubular sections of the second section. To reduce the size of the walking aid, one pulls in opposite directions on the first and second bitubular sections. Once the hinges are generally clear of the second section, the first section is folded over the second section in one direction. The third section is folded in the opposite direction in a similar fashion to accomplish the complete folding of the crutch.
