Adjustable splint

Claim 2

An adjustable splint assembly comprising a lower strut and an upper strut pivotably connected to said lower strut, one of said struts having at one end a pivotably mounted head portion defining a cam surface, an adjustable biasing means mounted within the other strut and biased into engagement with said cam surface for applying a quantifiable force tending to align or approximate said upper and lower struts, a palmer pressure pad, means attached to said palmer pressure pad providing both rotational and vertical adjustment of said palmer pressure pad and means connecting the palmer pressure pad to the end of the lower distal strut, said connecting means containing at least one lateral adjusting bar for medial and lateral adjustment of said palmer pressure pad and means for securing said splint assembly to the forearm.

Claim 3

An adjustable splint assembly according to claim 1 wherein the means attached to said palmer pressure pad therof comprises a base plate having an arcuate slot, a member fixed to said pad and projecting through said slot about which the pad rotates and a means slidably mounted thereto for vertical adjustment of said pad, said slidably mounted means containing means for receiving said bar for medial and lateral adjustment of said pad.

Claim 4

An adjustable splint assembly according to claim 1 wherein the adjustable biasing means is an adjustable spring means.

Claim 5

An adjustable splint assembly according to claim 2 wherein the adjustable spring means comprises a spring, a nose element connected to one end of said spring, and adjustable screw means engageable with the other end of said spring.

Claim 6

An adjustable splint assembly according to claim 4 wherein the adjustable screw means comprises a spring-abutting member, a screw member threadly engaged in a threaded member fixed to said strut, one end said screw member having a rotatable head and the other end of said screw member being engageable with said spring-abutting member.

Claim 7

An adjustable splint assembly according to claim 5 wherein the head is a socket.

Claim 8

An adjustable splint assembly according to claim 5 wherein the spring-abutting member is provided with an indicator marking.

Claim 9

An adjustable splint assembly according to claim 7 wherein the strut in which the adjustable spring means is mounted is hollow.

Claim 10

An adjustable splint assembly according to claim 8 wherein the hollow strut contains a slot having a scale along its length through which the screw member and indicator marking are visible, provided with a scale for setting the force to be applied.

Claim 11

An adjustable spring-loaded splint comprising a pair of lower struts and a pair of upper struts, each member of the pair of lower struts being pivotably connected to a member of the pair of upper struts, said members of each pair being spaced apart a distance to accomodate limb parts distal and proximal to the limb joint, at least one of said struts having at one end a pivotably mounted head portion defining a cam surface, an adjustable spring means, mounted within the strut pivotably connected to said cam surface-containing strut and biased into engagement with said cam surface, for applying a quantifiable force tending to align or approximate the cam surface-containing strut with the adjustable spring means, a palmer pressure pad, means attached to said palmer pressure pad providing both rotational and vertical adjustment of said palmer pressure pad, means interconnecting the ends of the lower or distal struts, means connecting the palmer pressure pad to said interconnecting means, said connecting means containing at least one lateral adjusting bar for medial and lateral adjustment of said palmer pressure pad, and means provided said pair and of lower struts for securely holding therebetween the forearm.

Claim 12

An adjustable spring-loaded splint comprising a pair of lower struts and a pair of upper struts, each member of the pair of lower struts being pivotably connected to a member of the pair of upper struts, said members of each pair being spaced apart a distance to accomodate limb parts distal and proximal to the limb joint, at least one of said struts having at one end a pivotably mounted head portion defining a cam surface, an adjustable spring means, mounted within the strut pivotably connected to said cam surface-containing strut and biased into engagement with said cam surface, for applying a quantifiable force tending to align or approximate the cam surface-containing strut with the adjustable spring means, a palmer pressure pad, means attached to said palmer pressure pad providing both rotational and vertical adjustment of said palmer pressure pad, means interconnecting the ends of the lower or distal struts, means connecting the palmer pressure pad to said interconnecting means, said connecting means containing at least one lateral adjusting bar for medial and lateral adjustment of said palmer pressure pad, and means provided said pair and of lower struts for securely holding therebetween the forearm.

Claim 13

An adjustable spring-loaded splint assembly according to claim 10 wherein the adjustable spring means comprises a spring, a nose element connected to one end of said spring, an adjustable screw means engageable with the other end of said spring.

Claim 14

An adjustable spring-loaded splint assembly according to claim 10 wherein the adjustable screw means comprises a spring-abutting member, a screw member threadly engaged in a threaded member fixed to said strut, one end of said screw member having a rotatable head and the other end of said screw member being engageable with said spring-abutting member.

Claim 15

An adjustable spring-loaded splint assembly according to claim 10 wherein the head is a socket.

Claim 16

An adjustable spring-loaded splint assembly according to claim 11 wherein the spring-abutting member is provided with an indicator marking.

Claim 17

An adjustable spring-loaded splint assembly according to claim 13 wherein the strut in which the spring means is mounted is hollow.

Claim 18

An adjustable spring-loaded splint assembly according to claim 15 wherein the hollow strut contains a slot having a scale along its length through which the screw member and indicator-marking are visible, provided with a scale for setting the force to be applied.
