Abstract
A compact, low-profile, prefabricated dynamic splint component for use in treating certain wrist conditions or injuries. The component is mounted on the wrist and forearm by means of a wrist gauntlet. It subjects the hand to a perpendicular force that urges the hand upward about the wrist joint while avoiding the application of any compression forces to the wrist.
Claims5
A low-profile dynamic splint device for mounting on the wrist and forearm of a user which subjects the associated hand to a perpendicular force about the wrist joint while substantially avoiding the application of any compression force to the wrist comprising:
- a first frame means having two spaced parallelly arranged pivotally mounted arms rigidly formed at their first ends to form a laterally extending proximal leg,
- a second frame means extending between the other ends of said arms,
- said arms each being bent in a common direction terminating in a plane,
- said second frame means comprising a wire, the end segments of which are bent in a common direction to lie in said plane connecting one to each of said arms and having a center section,
- a wrist mountable gauntlet,
- a first means for securing said leg to said gauntlet,
- a spring biasing means connected to said center section of said second frame means and a point on said gauntlet for rotating said arms in unison about a point on said first frame means toward said gauntlet,
- a palmar sling means for supporting the hand of a user, and
- a second means flexibly connecting said palmar sling means to said center section of said second frame means,
- whereby in use the component of force applied to the hand of a user by said spring means is substantially a perpendicular force directed outwardly from the dorsum of the associated hand of the user.
A low-profile dynamic splint device for mounting on the wrist and forearm of a user which subjects the associated hand to a perpendicular force about the wrist joint while substantially avoiding the application of any compression force to the wrist comprising:
- a first frame means having two spaced parallelly arranged pivotally mounted arms of substantially the same length rigidly formed at their first ends to form a laterally extending proximal leg,
- a second frame means extending between the other ends of said arms,
- said arms each being bent in a common direction terminating in a plane,
- said second frame means comprising a wire, the end segments of which are of different lengths and bent in a common direction to lie in said plane connecting one with each of said arms and having a center section,
- a wrist mountable gauntlet,
- a first means for securing said leg to said gauntlet,
- a spring biasing means connected to said center section of said second frame means and a point on said gauntlet for rotating said arms in unison about a point on said first frame means toward said gauntlet,
- palmar sling means for supporting the palm of a user, and
- a second means flexibly connecting said palmar means to said second frame means,
- whereby in use the component of force applied to the hand of a user by said spring means is substantially a perpendicular force directed outwardly from the dorsum of the associated hand of the user.
