LYTER H. CRAWFORD AND JOHN H. PRANTE, OF DALLAS, TEXAS.
SURGICAL SPLINT.Specification of Letters Patent. Patented Dec. 14, 1920.
Application filed April 26, 1919. Serial No. 292,966.To alf whom it may concern:
Be it known that we, LrrE H. CRAWFORD
and JOHN H. PRANTE, citizens of the United
States, residing at Dallas, in the county of
5 Dallas and State of Texas, have invented
certain new and useful Improvements in
Surgical Splints, of which the following is a
specification.
This invention 'relates to new and useful
10 improvements in surgical splints.
The purpose of the invention is to provide
means for holding certain members of the
human body in desired positions while un-
dergoing medical treatment, as well as to
15 assist such members in the performance of
natural functions.
In carrying out the invention a splint of
semi-rigid flexible material is provided and
involves the features of simplicity, easy ma-
20 nipulation and rapid adjustment. The term
"semi-rigid " as used herein is'intended to
cover a structure with sufficient rigidity to
sustain its shape or form; while material
may include soft rubber or any other suit-
25 able material.
The invention will be more readily under-
stood from a reading of the following speci-
fication and by reference to the accompany-
ing drawings, in which an example of the
30 invention is shown and wherein:
Figure 1 is a perspective view of the
splint,
Fig. 2 is a longitudinal sectional view of
the same, and
35 Fig. 3 is a rear end elevation of the same.
In the drawings the numeral 1 designates
an elongated body member somewhat U-
shaped in cross-section. The bottom 2 of
the member is thickened along its longitu-
40 dinal center and is transversely merged into
side walls 3; being at the same time gradu-
ally reduced in thickness toward each wall,whereby the walls are made thin and flexible.
The thickened bottom lends rigidity to the
member so that it not only sustains its shape 45
but supports any member of the human body
which is placed therein.
At the rear end of the body a loop 4 is
provided and arched from one side wall to
the other. The body member is tapered 50
from the rear to the front and abruptly
reduced at 5 at the front end by a well
rounded curving of the structure. The ex-
treme front end 7 of the member is cut at a
receding angle and a' contracted aperture 55
is provided. A loop 6 spans the front end.
The loops are preferably very thin but must
act to support the splint on the member be-
ing treated.
We have found.soft rubber to be very sat- 60
isfactory as a material because while it is
self sustaining it is also flexible and pliable,
readily lending itself to various distortions
and adjustments without pain or discomfort,
but other materials may be used. The splint s5
is sanitary being readily cleansed.
What we claim, is:
A surgical splint, comprising an integral
tubular member formed of semi-rigid ma-
terial, said tubular member having its lower 70
longitudinalportion thickened and gradually
decreasing in thickness upwardly and merg-
ing into relatively thin and flexible side
walls, said tubular member being provided
in its upper portion with a'longitudinal 75
opening extending through the same for the
greater portion of its length and spaced
from the forward and rear ends thereof for
providing end encircling bands.
In testimony whereof we affix our signa- 80
tures.
