Abstract
Abstract To enable a traction splint to be applied to a patient's limb without substantial disturbance of the limb, the splint comprises a thrust member in the form of a collar-like strap sidewardly applicable to the injured limb where it joins the trunk of the body, a U-shaped caliper, to accept the injured limb, having its free ends locatable in relation to stubs projecting from the thrust member, and having a crotch end to which a tether secured to the distal end of the injured limb is selectively attachable so to vary the tensional load imposed on the limb.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
200 words
A traction splint comprising: (a) a thrust member sidewardly applicable to the proximal end of a patient's limb, and, adapted, when so applied, to bear against the patient's trunk at that proximal end, said thrust member comprising a strap furnished with means to join the strap ends together and having a tubular body portion, and a stiff but flexible means housed within said body portion which renders the thrust member substantially straight and stiff to facilitate its application to said patient's limb from the side and yet flexible enough to be easily brought to ring-form around the limb, (b) a U-shaped caliper including length adjustable side members able to flank a broken limb longitudinally and on either side thereof, with the caliper crotch spaced from the distal end of the patient's limb, (c) means to locate and retain location of the free ends of said side members in relation to said thrust member, and (d) tension means able to take hold of the distal end of a patient's limb which has said caliper and said thrust member applied thereto as aforesaid, and adapted for attachment to said caliper crotch thereby to exert a degree of tension on the patient's limb.
Claim 2
Dependent Claim
200 words
A traction splint comprising: (a) a thrust member sidewardly applicable to the proximal end of a patient's limb, and, adapted, when so applied, to bear against the patient's trunk at that proximal end, said thrust member comprising a strap furnished with means to join the strap ends together and having a tubular body portion, and a stiff but flexible means housed within said body portion which renders the thrust member substantially straight and stiff to facilitate its application to said patient's limb from the side and yet flexible enough to be easily brought to ring-form around the limb, (b) a U-shaped caliper including length adjustable side members able to flank a broken limb longitudinally and on either side thereof, with the caliper crotch spaced from the distal end of the patient's limb, (c) means to locate and retain location of the free ends of said side members in relation to said thrust member, and (d) tension means able to take hold of the distal end of a patient's limb which has said caliper and said thrust member applied thereto as aforesaid, and adapted for attachment to said caliper crotch thereby to exert a degree of tension on the patient's limb.
Claim 3
Dependent Claim
15 words
A splint according to claim 1 wherein said strap is externally clad with cushioning material.
Claim 4
Dependent Claim
67 words
A splint according to claim 1 wherein said caliper consists of a pair of telescopically-adjustable, tubular side members and a bridge plate which constitutes a crotch portion for said side members; said side members each being furnished with chuck means to hold selected adjustment of the member, and said bridge plate being furnished with means for selective attachment thereto of a tether secured to the patient's limb.
Claim 5
Dependent Claim
52 words
A splint according to any one of claims 1, 2 or 3 wherein said means to locate and retain location of said side members relative to said thrust member comprise tubular distal end portions on said side members, and location stubs on said thrust member able to enter said tubular end portions.
Claim 6
Dependent Claim
42 words
A splint according to claim 4 wherein said tension means comprise a sling attachable to the distal end of a broken limb, an upstanding peg on said bridge plate, and a tether to join said sling to said peg in selected adjustment.
Claim 7
Dependent Claim
32 words
The combination with a splint according to claim 3 of a stiff bridge-piece comprising a limb support plate and curled edge margins on said plate able to engage about said side members.
Claim 8
Dependent Claim
34 words
The combination with a splint according to claim 3, of down-bent portions on the crotch ends of said side-members, and a U-shaped support tube having tubular free ends able to accept said down-bent portions.
