Description
Nov. 11, 1969 G. F. HARE COMBINED SPLINT AND TRACTION DEVICE Filed June 29, 1967 GLENN F. HARE INVENTOR United States Patent U.S. Cl. 128-85 6 Claims ABSTRACT OF THE DISCLOSURE An improved splint and leg traction means with a ratchet arrangement for applying and maintaining traction on a fractured leg including a member for retaining the foot in a supported position and novel transverse splint straps.
BACKGROUND OF INVENTION Fractures of the extremities require appropriate splinting. It is epitomized in the aphorism Splint em where they lie. It is generally recognized that splints should be applied at the scene of injury before the patient is moved.
For thigh and leg fractures the application of a slow, steady pull to relax the muscles and not produce irritation is recommended therapy. A gentle and steady pull should be in the long axis of the extremity. This brings the fragment which can be controlled into alignment with the fragment which cannot. Chance for injury to soft tissue, and blood vessels are reduced and relief from pain is accomplished in this manner. A small fracture might otherwise mean a large disability.
Prior first aid art includes the Thomas ring splint. Tongue depressors for a Spanish Windlass action to increase and maintain traction is advised. The use of a foot support, if available is suggested. Thereafter the patient should be transported with extreme care and gentleness. See The Management of Fractures and Soft Tissue Injuries, 2nd edition, American College of Surgeons, p. 78.
Upon hospitalization, the prior art leaves something to be desired. Skeletal traction has the advantage that it is more efficient than adhesives and glue applied to the skin; more weight can be used and is more comfortable, if applied correctly. But according to Management of Fractures, etc., Conwell and Reynolds, 7th edition, p. 100, In many clinics skeletal traction has become a lost art. Also, even under the best of conditions, the bone will become infected from the pin wound.
SUMMARY My device has a heel support tape as a part of the sling and traction combination. This, coupled with a U-shaped member under the heel permits easy and safe handling of patients. A ratchet arrangement is adapted to sensitive control of the amount of force applied to the leg. Even though the force is critical and should be varied, the continuous use of my device is acceptable at all stages of therapy.
DESCRIPTION OF THE PREFERRED EMBODIMENT In the drawing:
FIGURE 1 is a perspective view of the device, complete except the foot tape support.
FIGURE 2 is a perspective view of the foot tape support with the heel portion.
FIGURE 3 is a perspective view of the device showing it in use.
FIGURE 4 is a perspective view of a modification of my device suitable for adapting to the existing Thomas splint.
FIGURE 5 is a close-up perspective of the foot end of 3,477,428 Patented Nov. 11, 1969 ICC the device with arrows to illustrate the direction of force.
FIGURE 6 is a brake detail part of the ratchet assembly, and
FIGURE 7 is a detail of an adjustable portion of the parallel splint rods.
In the drawing, wherein like numerals represent like parts throughout, the numeral 1 is one of two identical parallel rod members characteristic of the well known Thomas splint. The rods telescope into tubular sections 2 to accommodate patients with legs of various lengths. As shown in FIGURE 7, a locking arrangement may be formed of pin 39 on spring-steel arm 9. It fits into a plurality of recesses 37 through orifice 38 of item 2.
Elements transverse to the parallel members include the half ring cradle 6 for patients leg 36. It is swively mounted at the ends of 2 for movement in the direction of the arrow by dual universal joints 5. Also traversing the space between the rods are a plurality of supports 3, preferably three in number, at regular intervals, free to slide in the direction of arrows 14 of FIGURE 1. With each support are elastic bands 8 and 10 two sections which lock over the 'leg in a bandage fashion. For this I prefer to use modern cohesive materials which grip without tying, buckling or snapping. Completing the transverse elements is non-elastic strap 4 with a buckle and wire brackets 7. It also may slide alongtubular frame 2.
At the foot end of the device I have provided novel U- shaped support member 12 secured to rods 1 by brackets 24 on each side. This obivates the necessity of a separate foot mount and keeps the foot from bumping a hard surface.
Much of my invention resides in a ratchet pulling means or system 13. It comprises a spool 28 with spacers 26 which revolves in the direction of arrows of FIGURE 5 by manual operation of handle 11. This pulls the foot and leg of the patient in the direction of the arrows of FIGURE 3. When desired tension is acquired spring steel brake 25 engages teeth 35 of cog 27, see FIGURE 6. Finger pressure at the place indicated by arrow 33 moves item 25 in direction of arrow 34 releasing the ratchet for a new position. A spring metal handle retainer 30 may look onto handle 11 and swing out of the way when the handle is operated. Nylon belt 29 with metal strip 31 wraps onto spool 28 as illustrated.
Lastly, a modification of the existing Thomas splint 19 is within the scope of my invention. This is shown in FIG- URE 4. The Thomas splint is made for either leg by simply turning it over. In such instances I have a rectangular support member 21 for use on either leg. My modification is an adapter for splint 19. It has cross bar 22 to align with and abut splint cross piece 23 and it is secured thereto by a plurality of clamps 20, as illustrated. With the modification, conventional Thomas splints may be converted into my novel combination.
