Patent number: 5327882Abstract: A continuous motion device for the therapy and rehabilitation of a patient's hand and fingers comprises a splint adapted to be mounted to the patient's forearm and hand, a gear housing rotatably mounted around a reversible motor, with the reversible motor driving a gear mechanism provided in the gear housing. The gear mechanism driving a digit attachment member in a rotational movement therewith. When actuated, the reversible motor causes the gear housing to rotate about the axis of the motor with the digit attachment member counter-rotating relative to the gear housing about another axis spaced apart from and parallel to the motor axis, whereby the absolute motion of the digit attachment member and therefore of the patient's fingers follow a compound spiral. The compound spiral, depending on the ratios of the gears of the gear mechanism, can follow one of a series of multiple lobed compound spirals, having open or closed loops.Type: GrantFiled: May 5, 1993Date of Patent: July 12, 1994Assignee: Toronto Medical Corp.Inventors: John Saringer, Andrew Galbreath

Patent number: 5067479Abstract: A device for providing continuous passive motion therapy to a patient's wrist comprises a base removably attached to the forearm of the patient rearwards of the wrist. The base includes horizontal turntable which can be secured thereon in a selected position. A wheel driven by a motor is rotatably mounted on the turntable for rotation in a vertical plane. A telescopic motion transmission which is provided between the wheel and a handle is mounted eccentrically to an eccentric disk which in turn is eccentrically and parallely mounted on the wheel. The eccentric disk may be rotated relative to the wheel to vary the absolute eccentricity of the motion transmission with respect to the rotation axis of the wheel. The handle which is universally mounted to the motion transmission includes a grip. Therefore, a rotation of the wheel and thus of the eccentric disk caused the motion transmission to pivot and to impart to the patient's hand a preselected pivoting motion about the wrist being treated.Type: GrantFiled: August 21, 1990Date of Patent: November 26, 1991Assignee: Toronto Medical Corp.Inventors: John Saringer, Andrew Galbreath

Patent number: 4930497Abstract: An apparatus is provided for imparting passive motion exercise to a lower limb of a patient. The apparatus includes a base and a thigh support member having a pair of elongated parallel spaced-apart brace members pivoted at their respective first ends to the base. The other ends of the thigh support brace members terminate at a mechanical hinge. A lower leg support includes a pair of parallel spaced-apart brace members extending from the mechanical hinge. The base is provided with a slide surface for supporting the other ends of the brace members of the lower leg support while allowing for extension and retraction thereof. The mechanical hinge includes at least a shaft fixed to the thigh support with the brace members lower leg support journaled to the shaft. An electric motor is mounted to the lower leg support to drive the shaft such that the angular movement is provided between the thigh support and the lower leg support, whereby the angular speed is maintained constant when motor speed is constant.Type: GrantFiled: January 23, 1989Date of Patent: June 5, 1990Assignee: Toronto Medical Corp.Inventor: John H. Saringer

Patent number: 4716889Abstract: An apparatus for imparting back and forth motion in a slow rhythmic cycle for mobilizing a human joint. An elongated support is provided with a traveller mounted thereon for reciprocating linear movement relative thereto. The traveller is provided with a connector for operatively engaging a limb of the body adjacent to the joint to be mobilized. A reversible motor is provided for driving the traveller through a reciprocating linear stroke and for reversing the direction of travel of the traveller at any point in its path of travel in response to a sensed predetermined load.Type: GrantFiled: August 22, 1985Date of Patent: January 5, 1988Assignee: Toronto Medical Corp.Inventor: John H. Saringer

Patent number: 4665900Abstract: An apparatus for applying continuous passive motion to the joints of several fingers of the hand at the same time. It includes a support housing for mounting it on the forearm, carrying a motor and a traveller movable by a motor through an elongated path in a reciprocating movement. A connecting rod connects the traveller to a manifold block which, in turn, has elements connected to several fingers whereby their joints are mobilized simultaneously.Type: GrantFiled: December 31, 1984Date of Patent: May 19, 1987Assignee: Toronto Medical Corp.Inventor: John H. Saringer
