Description
BACKGROUND OF THE INVENTION
The present invention relates to a traction band or strip which is
capable of being attached to the limb of a patient so that traction
applying means may be attached thereto to apply tension after the
limb has been set.
Heretofore, devices for attachment to a tensioning apparatus were
customarily attached to the patient's fractured limb using ordinary
surgical adhesive tape. This approach is undesirable because of the
painful consequences which frequently result, for example, due to
allergic reactions by the patient or due to the removal of the
upper layer of skin on removing the tape after a long duration of
use. This approach is also disadvantageous since it does not permit
ventilation of the wrapped portion of the limb, and the adhesive
tape does not provide cushioning for the comfort of the
patient.
Other approaches have utilized traction bands which have been
provided with a spongy material for improving the patient's comfort
and with means for adhesively securing the traction band to the
limb. The use of an ace bandage wrapped around a traction band
having a layer of adhesive of the pressure sensitive type on its
inner surface for attachment to the limb has also been proposed in
the prior art.
In general, these approaches have been subject to one or more
drawbacks such as still adhesively securing the traction band
directly to the patient's skin, using a system which is
uncomfortable and provides poor ventilation or which is difficult
to apply and adjust. In addition, such prior art systems included
components which were not durable or washable and comprised several
separate parts.
SUMMARY OF THE INVENTION
It is a principal object of the present invention to provide an
improved traction band of a durable one-piece construction. Another
principal object of the invention is to provide a traction band
which may be readily applied and removed from the limb without
causing discomfort to the patient.
Briefly, a presently preferred embodiment of the invention
comprises a multi-ply fabric tension band which may be secured on
opposite sides of the limb, especially a leg, with a loop formed at
the distal end of the limb for attachment of a conventional
tensioning system via a spreader bar. Integral with the
longitudinally extending tension band are a plurality of
transversely extending elastic securing bands which are permanently
attached to the two halves of the traction band to keep these
strips in proper alignment when in use. The elastic bands, after
being wrapped around the limb, are secured in place by detachable
fasteners, preverably by interengagement of hook and loop type
fabric fasteners. To facilitate removal of the device, it is
presently preferred that a longitudinally extending opening strip
or cord interconnect the elastic bands. In this way, a pull on the
upper elastic band to open it also detaches the fastening elements
of the remaining elastic bands at the same time.
This one-piece construction traction band is made of material which
allows ventilation therethrough. In addition, the material is
durable and washable.
The above and other objects, features, and advantages of the
invention will become more apparent as this description proceeds
when considered in conjunction with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is essentially a perspective view of a presently preferred
embodiment of a tension band of the invention shown in position on
the foot of a patient with a portion of one elastic band broken
away for the sake of clarity.
FIG. 2 is a side view of the tension band of FIG. 1 folded
flat.
DETAILED DESCRIPTION OF THE INVENTION
Referring now to the drawings wherein like reference numerals refer
to like and corresponding parts in the several views, reference
numeral 10 generally designates the integral tension band and
fastener apparatus of the invention. The traction band itself is
comprised of a three-ply soft, flexible, non-adhesive cotton
flannel strip having longitudinally extending portions 12 and 14
connected to each other at their lower by a loop 16 which is
disposed beneath the heel of the foot 17 of the patient.
Three transversely extending elastic bands 18, 20 and 22 are
integrally connected to the opposite edges of traction band
portions 12 and 14 of the traction band by longitudinal rows of
stitching 23. These elastic bands are preferably made of the same
type material utilized in making elastic bandages and are utilized
to secure the traction band to the limb. As shown in the drawings,
the lengths of the elastic bands 18, 20 and 22 progressively
decrease towards the loop 16. Thus, when the tension band is
applied to the leg of the patient the longer upper elastic band 18
is wrapped around a thicker part of the limb than the middle
elastic band 20, and the lower, smallest elastic band 22 is
intended to be fastened around the ankle of the patient with the
loop 16 being beneath the heel of the foot for attachment to a
spreader bar. The spreader bar may be connected to any conventional
traction system including a series of weights and pulleys (not
shown).
Attached to the inside surface of the left end of the elastic bands
18, 20 and 22 are fasteners 24 which are intended to be detachably
connected to complementary fasteners 26 on the outside of the other
ends of the elastic bands. The complementary fasteners 24 and 26
preferably consist of strips of loop type fasteners cooperating
with strips of hook type fasteners respectively. Material used in
making such fasteners is commercially available under the Trademark
Velcro. Typical fasteners of this type are disclosed in de Mestral,
U.S. Pat. No. 2,717,437.
In use, the patient's foot is placed in the loop 16 and the
longitudinally extending portions 12 and 14 of the traction band
are positioned along opposite sides of the patient's leg to protect
the nerves in the leg. The elasticity of bands 18, 20 and 22
permits the proper positioning of portions 12 and 14. It should be
observed that the distance between portions 12 and 14 progressively
increases in an upward direction to compensate for the increasing
circumference of the leg in an upward direction. With the
tensioning band in proper position, elastic bands 18, 20 and 22 are
now stretched about the leg and the bands are fastened in position
by interengaging the respective fasteners 24 and 26. These elastic
bands are stretchable not only to facilitate putting on the device
but also for the comfort of the patient and so that circulation in
the limb is not adversely affected. In the absence of such stretch,
a tight binding about the leg could cause swelling and potentially
severe complications.
A thin cotton fabric rib 28 is sewn to the left ends of elastic
bands 18, 20 and 22 adjacent the fasteners 24. If one of the ends
of the elastic bands, for example, the end of the larger, upper
elastic band 18 is pulled to detach the fasteners 24, 26 of this
band; the rib 28 acts in the nature of a rip-cord to simultaneously
detach the fasteners of elastic bands 20 and 22. In this way, the
patient is able to open all of the fasteners even though the
patient may only be able to conveniently reach the end of the upper
elastic band 18. This quick release feature is especially
advantageous in the event of an emergency, for example, should it
be necessary to evacuate the patient. Because of the rib 28 the
patient is able to quickly disconnect himself from the tensioning
system even without the services of an attendant.
While a presently preferred embodiment of the invention has been
shown and described with particularity, various changes and
modifications may suggest themselves to those of ordinary skill in
the art upon being apprised of the present invention. It is
intended to encompass all such changes and modifications as fall
within the scope and spirit of the appended claims.
