Specification of Letters Patent.

Patented May 18', 1920.

Application filed December 31, 1918. Serial No. 269,100.

(FILED UNDER THE ACT OF MARCH 3, 1883, 22 STAT. I.., 625.)

T 0 all whom it may concern Be it known that I, ROBERT D. MAonoX, major, Med. Dept, U. S. Army, a citizen of the United States, stationed at Vashington, D. G., have invented an Improvement in Arm-Abduction Splints, of which the following is a specification.

The invention described herein may be used by the Government, or any of its officers or employees in prosecution of work for the Government, or by any other person in the United States, without payment of any royalty thereon.

This invention relates to surgical devices adapted to retain the arm of the patient in any desired position relatively to the body during treatment for fracture and other injuries especially of the upper arm or shoulder and has for one of its objects to simplify and improve the construction and increase the efiiciency and utility of devices of this character.

Another object of the invention is to provide a simply constructed device of this character including a supporting frame, body engaging pads adjustably coupled to the frame, an upper arm engaging support adjustably connected to the frame, and a fore arm supporting portion adjustably connected to the upper arm supporting portion.

With these and other objects in view the invention consists of certain novel constructions and combinations of parts as will be hereinafter more fully described and pointed out in the claims.

In the drawings illustrative of the preferred embodiment of the invention Figure 1 is a perspective View, of the improved device.

Fig. 2 is a perspective view of one of the body engaging pad devices and a portion of the supporting frame illustrating the construction of the pad adjusting devices.

Fig. 3 is a plan view illustrating the connection between the frame and the upper arm support.

F Fig. 4 is a side view of the parts shown in ig. 3. The supporting frame or standard includes a substantially vertical portion 10,

preferably oblong transversely, and with a circular upper portion 11. Slidably engaging the portion 10 of the frame are curved plates 1213 the plates having protecting lining pads 14-15 and likewise provided respectively with holding devices such as straps 1617 and buckles 18-19 whereby the plates and the supporting frame may be connected to the body of the patient.

Adjustably engaging over the rounded portion 11 of the frame is a sleeve 20, split at 21 and provided with lateral lugs 22 to receive a binding bolt 23. By this means the sleeve may be adjustably clamped upon the standard both vertically and rotatably. At its upper end this sleeve 21 is directed laterally and terminates in a radially notched disk 24. v

Another sleeve 25 is provided and formed with a radially notched disk 26 coacting with the disk 24:, the two disks being united by a clamp bolt 27 and wing nut 28. By this means the sleeves 20 and 25' may be adjustably coupled and held at any required angle, as hereafter explained. V

The fore arm support includes a bar 29 having a rounded portion 30 slidably and rotatably engaging in the sleeve '25, and clamped in position through the coaction of a split 31, ears 32 and clamp bolt 33 and wing nut 34, as shown.

The sleeves 20 and 25 are each formed with continuous bore so that the rounded portions 11 and 30 of the supports 10 and 29 extend entirely therethrough, to increase the extent of the adjustment.

The sleeves 20 and 25 are formed respec tively with lateral offsets and together with the disks 24 and 26 are duplicates so that they can be interchangeably employed, and by forming them with the ofi'sets they can be applied to the patient without inconvenience, or contacting with his body.

Adjustably engaging the bar- 29 is an upper arm supporting plate 35 having a protecting pad 36.

The fore arm support includes a bar 37 having a forearm supporting plate 38 provided with a protecting pad 39.

The confronting ends of the members 29 and 37 are provided with radially toothed disks 410- 11 united by a clamp bolt 42, to enable the parts to be adjusted laterally and clamped in adjusted position.

The several plates 12-13-35 and 38 are secured adjustably to the frame members by suitable clip devices, and as the clip devices are precisely alike the description of one will suflice for all. Each clip device comprises a plate 43 bent to engage over the frame member and with distended ends 44 to bear against the adjacent face of the member 121335 or 38 as the case may be. One of the extensions is riveted or otherwise permanently secured as shown at 45 to the adjacent plate while the other extension is held in position by a wing nut and bolt 46. By this means the clip devices may be pinched against the frame and rigidly support the pad supporting plates in adjusted position by friction. The pad devices may thus be adjusted longitudinally of the frame and held in adjusted position by simply actuating the thumb nuts of the bolts 45.

The pad supports 35 and 38 are provided with straps or other means represented at 47 for holding the pad portions to the arms, as indicated.

The improved device will thus be adapted to bodies and arms of various sizes and lengths to enable the pads to be applied to different portions of the arm, or to adapt the device to different sized patients.

Having thus described the invention what is desired to secure by Letters Patent is:

l. A device of the class described comprising a standard having means for supporting said device upon the body of a patient, said means adjustable on the standard, a sleeve adjustable longitudinally of the standard and independently of the body supporting means, a bar adapted to support an arm of the patient, a sleeve adjustable l0ngitudinally of the bar, and means for swingingly uniting said sleeves.

2. A device of the class described comprising a standard, supports adapted to bear upon the body of a patient, means for independently adjusting said supports upon the standard, a bar carrying supports for the arm of the patient, connecting means between the standard and bar formed of coacting members swingingly united, means for adjusting said connecting means longitudinally of said standard, and means for adjusting said bar longitudinally of said connecting means.

3. A device of the class described comprising a standard having means for supstandard, body encircling supports adjust-' able on said standard, an arm supporting bar, and articulated sleeves connecting the arm and the bar and adjustable thereon.

5. An arm abduction splint comprising a standard, body encircling supports adjustable on said standard, an arm supporting bar, articulated sleeves connecting the standard and the bar, and means for clamping the sleeves at any angular degree of articulation.
