Surgical splint assembly
Abstract
A surgical splint assembly includes a plurality of substantially
identical rigid splint units, each of which is formed from a metal
strip that is narrower at one end than the other and provided with
integral side flanges turned inwardly toward each other. The
portions of the flanges at the wide end of the strip are spaced
from the strip a distance about equal to twice the thickness of the
strip, while the portions of the flanges at the opposite end are
substantially flat against the strip. The narrower end of each unit
is insertable in a like splint unit between the wide end of its
strip and the flanges spaced therefrom to telescopically connect
the two units together. Means can also be provided for detachably
connecting a pair of these splint units edge to edge to double the
width of the splint.

Claims
We claim:
1. A surgical splint assembly comprising a plurality of
substantially identical rigid splint units, each of said units
being in the form of a single metal strip tapered in width from end
to end and provided with integral side flanges turned inwardly
toward each other, the free edges of the flanges being opposed to
each other and spaced apart, the portions of said flanges at the
wide end of the strip being spaced from the strip a distance equal
to substantially twice the thickness of the strip, and the portions
of said flanges at the opposite end of the strip being disposed
substantially flat against the strip, the narrower end of each unit
being removably inserted in a like splint unit between the wide end
of its strip and the flanges spaced therefrom to telescopically
wedge the two units together.
2. A surgical splint according to claim 1, including rigid means
for detachably connecting two of said splint units edge to edge to
hold them in the same plane, said means having end portions for
insertion between said strips and flanges.
3. A surgical splint according to claim 2, in which said connecting
means is a clip comprising a pair of laterally spaced rigid plates,
each plate being insertable in the wide end of a splint between its
strip and its adjoining flanges, and a rigid bar extending across
the flanges at the inner edges of the two splint units, the ends of
the bar being rigidly secured to the central portions of said
plates.
4. A surgical splint according to claim 3, in which the narrower
end of each of said strips is provided with a hole, and the
opposite end of the strip has a detent for projecting into the hole
in a like splint unit to hold the telescoped units together, said
plates being bowed outwardly away from the adjoining strips to
permit the plates to be moved across said detents.
Description
There is need for a splint that can be adjusted in length for use
on either arms or legs, and yet which can be broken down into short
sections that can be stored in a typical first-aid kit until
needed. U.S. Pat. No. 2,269,065 shows a surgical splint that is
adjustable in length, but which has some shortcomings. One of these
is that one of the splint sections consists of only a flat metal
strip, which lacks the strength and resistance to bending that the
other strip possesses by reason of its side flanges. Another
disadvantage is that the length of the splint is limited because no
provision is made for connecting more than two sections together.
There also is no provision for connecting like splints side by side
to provide a wider splint.
It is among the object of this invention to provide a surgical
splint assembly in which there can be any desired number of
relatively short splint units of substantially identical
construction, in which each splint unit is as strong as every other
splint unit, in which a splint of any desired length can be formed,
in which separate fastening members are not required for holding
the splint units together end to end, and in which provision is
made for connecting splint units side by side to increase the width
of a splint.
The invention is illustrated in the accompanying drawings, in
which
FIG. 1 is a front view of a splint unit;
FIG. 2 is an enlarged fragmentary vertical section taken on the
line II--II of FIG. 1;
FIG. 3 is a fragmentary front view of two splint units telescoped
together;
FIG. 4 is a side view of a different arrangement of two splint
units; and
FIG. 5 is an enlarged cross section taken on the line V--V of FIG.
4.
Referring to the drawings, any desired number of substantially
identical splint units 1 like the one shown in FIGS. 1 and 2 are
provided, which can be connected end to end to form a splint of any
desired length. Each of these units is relatively short; for
example, about eight inches long, so that it can fit inside a
typical first aid kit. Each unit is formed from a metal strip 2
that is slightly narrower at one end than at the opposite end and
that is provided with integral side flanges 3 that are turned
inwardly toward each other so that they overlie the strip to some
extent. Preferably, the strip is tapered uniformly from end to end.
Extending inwardly from the narrower end of the strip for at least
about an inch, the side flanges are pressed down against the strip.
For the rest of the way the flanges are spaced from the strip a
distance equal to substantially twice the thickness of the strip.
The width and thickness of the narrower end of the splint unit are
such that it can be inserted a short distance into another of the
splint units between the wide end of the latter's strip and its
flanges, as shown in FIG. 3, whereby the adjoining ends of the two
units are telescoped together. They fit snugly together to provide
a rigid splint. The spacing of the major portions of the flanges
from the strip strengthens the splint against bending.
In order to hold the two splint units together and against
accidental separation, each of them has a hole 5 in one end of its
strip and a detent 6 pressed out of the opposite end. In the areas
where the two units are telescoped together, the detent on one unit
projects into the hole in the other unit. This prevents separation
of the two splint units unless considerable force is applied to
them in opposite directions to pull them apart lengthwise.
Preferably, the hole is in the narrower end of the unit and the
detent is at the opposite end so that there will be no projection
from the back side of the strip opposite the side flanges. As many
splint units as desired can be connected together end to end in the
manner just described and all of them will have the same resistance
to bending because they are all made alike, which also is an
economical way to make splints. There are no separate fastening
members to hold the units together, the registering detents and
holes being sufficient for that purpose. This also reduces the cost
of the splints.
Another feature of this invention is that two or more of the units
can be connected edge to edge to at least double the width of the
splint. For this purpose, as shown in FIGS. 4 and 5, a clip is
provided that can clamp onto two splint units disposed edge to
edge. Such a clip is formed from a pair of laterally spaced rigid
plates 8, to the central portion of which the opposite ends of a
stiff bar 9 is secured, such as by welding. The width of each plate
is such that it can be inserted in the wide end of a splint unit
between its strip 2 and its adjoining side flanges. When the clip
plates are thus inserted in two side-by-side splint units, the
connecting bar 9 extends across the flanges 3 at the inner or
adjacent edges of the units. The clip will hold the two splint
units edge-to-edge. To enable the clip plates to be slid across the
detents 6, the plates can be bowed outwardly away from the strips
as shown in FIG. 5. A third splint section could be added by using
a second clip, which would connect the third unit to one of the
other units. Of course, the length of this multiple-width splint
can be increased by adding splint units to its ends in the manner
first described herein.
According to the provisions of the patent statutes, we have
explained the principle of our invention and have illustrated and
described what we now consider to represent its best embodiment.
However, we desire to have it understood that, within the scope of
the appended claims, the invention may be practiced otherwise than
as specifically illustrated and described.
