1 Claim.

board 5 that is generally oblong and is preferably formed of light metal, such as steekbeing also preferably perforated as at B to further materially reduce the weight thereof.

The board 6 is adapted to have placed thereon the arm of the patient and for the forearm of the patient there is provided a rest I.

As shown, the rest I embodies a body member 8 that is raised intermediate its ends, and adjacent one end as at 9 and has a gradual slope toward one end as at Ill and a more pronounced slope II in the direction of the opposite end;

Among the objects of the present invention is to improve and simplify the splint to the end that the same will be more efficient and easily applicable; the intent, object, and purpose of the invention being to provide a splint of this character whereby intravenous infusions and transfusions may be administered with efficiency, while a patient is in the progress of being moved or transported from one location to another, as from one bed to another, or in an ambulance from one location to another, such as from the home or street to the hospital.

The present invention, together with its many objects and advantages will be appreciated from a study of the following description taken in connection with the accompanying drawings wherein Figure 1 is a perspective view of an intravenous splint embodying the features of the present invention.

Figure 2 is a fragmentary bottom plan view illustrating certain details hereinafter more fully referred to.

Figure '3 is a longitudinal sectional view through the splint.

Figure 4 is a transverse sectional view through the splint at the elbow clamp-equipped end portion thereof.

Figure 5 is a transverse sectional view through the splint and illustrating certain details hereinafter more fully referred to.

Figure 6 is a fragmentary sectional view through the body of the forearm rest illustrating a slightly modified form of the invention as hereinafter more fully referred to.

Figure 7 is a side elevational view of a modifled form of clamp and holder therefor.

' Figure 8 is a fragmentary perspective view of clamp holder hereinafter more fully referred to.

Referring more in detail to the drawings, it will be seen that in accordance with the invention, this form of splint embodies a main body with the top of the body 8 being somewhat concave in crosssection to conformably receive the forearm of the patient. a

Also secured to the topside of the body 8 of the rest is a pad or surface covering i2 of rubber or other suitable soft and yielding material.

The rest 1 is secured at the desired positionof adjustment longitudinally of the base or board 5 through the medium of short stud bolts it that screw-threadedly engage bosses H on the underside of the rest body 8.

The bosses H are accommodated in a longitudinal slot it provided therefor in the base or board 5 and coact therewith in restraining shifting movement of the rest I in a direction longitudinally of the base or board 5.

To assist in maintaining the forearm at the hand in position on the rest I, the same has disposed transversely thereof a restraining strap l 8 that at its opposite ends is provided with eyelets II to engage hooks i8 that project from opposite sides of the body 8 of the rest I. The hooks l8 may be either of the shape shown in Figure l, or of the shape suggested in Figure 6, and in which latter figure the hooks are indicated by the reference numeral I80.

The restraining strap I8 is characterized by the provision of a slot l9 therein through which the thumb extends, and a buckle-equipped strap portion 20 that can be adjusted for contracting the strap I 8 across the hand as the size of the hand of the patient may require. To support the arm of the patient at the back of the elbow there is provided at the end of theboard 5 remote from the rest 1 a substantially wedge-shaped rest 20. The rest 20 may be cemented or otherwise positively secured to the board 5, and the board 5, in the region of the rest 20, is provided with a transverse slot, or opening 2 I, so that minimum resistance is offered by the board to the rest 20, with the result that the full benefits of the resiliency of the rest will inure to the advantage of the patient, thus adding further to the comfortableness of the splint; the rest 23 being preferably formed solely of sponge rubber, or some other similar resilient substance.

Also, in accordance with the present invention. there is provided an adjustable clamp, indicated generally by the reference numeral 22, for clamping the arm at the elbow.

The clamp 22 comprises a pair of substantially identical, opposed jaws 23-23.

Each of the jaws 23 embodies a body part formedof some light metal, preferably aluminum, in the form of a plate curved transversely and having a marginal flange projecting therefrom at the convex side of the plate.

Upper and lower flanges are apertured to accommodate a retaining bolt 24 that extends upwardly through the apertures in the flanges and also through a transverse slot 23 in the board or base member 3 to secure the associated jaw at the desired position in a direction transversely'of the plate or base member 5.

The confronting concave faces of the clamp members are covered with sheets 28 of sponge rubber, or other suitable resilient material.

To retain the arm, at the elbow, clamped between the jaws 23 of the clamp 22, and against being pulled upwardly from between the jaws, the space between said jaws 23, adjacent one end of the clamp, is bridged by a restraining, adjustable strap 26.

'I'he strap 26, as shown to advantage in Figure 1, is trained through suitable loops 2! provided on the uppermost flanges of the jaw members as shown.

From the description thus far, it will be seen that the arm rests on the base member 5 with the forearm and hand supported by the rest I, the elbow secured between the jaws of the clamp 22, and the arm in back of the elbow supported or sustained by the rest 20. Thus the arm is held in position to facilitate the giving of an intravenous infusion or a blood transfusion, as conditions may require.

Further, and to render the device more comfortable to the patient, the base member 3, inwardly from the rest 20, is provided with an opening 28 at a point where the elbow joint would be most likely to rest on the member 5.

Seated in the opening 28 is a cushion 23 serving as a rest for the elbow joint.

Further in accordance with the present invention the base 5, adjacent one edge thereof, is pro- In lieu of the support 3 I, resort may be had to a support of a flexible type and such as suggested in Figure 7 and indicated by the reference numeral 42.

The support 42 is in the form of a flexible standard, or post 43 equipped at one end with a threaded stem 44 and nut and washer means 46 through the medium of which, and the aforementioned slot 30, such support 42 is secured to the base or board I at the desired position lengthwise vided with a slot 30 elongated longitudinally thereof, and for the purpose of facilitating the securing thereto of a support for a surgical needle, syringe clamp, or other surgical instrument that may be desired.

In Figure 1, one such form of support is shown and indicated by the reference numeral 3 I.

The support 3| embodies a tubular standard 32 that atone end is provided with a threaded pin or stud 33 that extends through the slot 30 and is equipped with a nut and washer assembly 34, and through the medium of which the support 30 is secured at the desired position of adjustment lengthwise of the board or base member 5.

Further, the support at embodies a vertically shiftable and adjustable rod 35 that has a threaded section telescoped by the standard 3|, and a wing nut 36 threadedly engaged with the threaded section of the rod 35 and adapted to be threaded home against the upper end of the standard 3| for securing the rod 35 at the desired position of vertical adjustment.

of said base or board.

At the upper, or free end thereof the standard 43 of support 42 has pivoted thereto, as at 48, the shank portion of a clamp indicated generally by the reference numeral 41.

Clamp 41 is illustrated as being of a type particularly designed for engagement with a surgical needle of a type other than an intravenous syringe, and. for example, as might be employed in giving a blood transfusion.

Other types of supports and clamps may be resorted to and, for example, a support such as hereinbefore referred to and indicated by the reference numeral 30, may be employed but in a modified form, as, for example, instead of having the arm 31 of the rod 35 terminating in a slotted extension 38, said arm, as suggested in Figure 8 and indicated by thereierence numeral 31a, may terminate at its free end in an upstanding integral shank 48 on which is sleeved a sleeve element 49 equipped with a set screw 50 through the medium of which the sleeve 49 is secured at the desired position of vertical adjustment on the shank 48.

Also, as shown in Figure 8, the sleeve 43 has pivoted thereto a second sleeve 5| through which is trained a carrier rod 52, and from which rod a clamp or the like, or a syringe needle, or other surgical appliance may be suspended.

Also, in accordance with the present invention. the board or base member 5 has tapped into it, adjacent one corner thereof, a threaded opening 63 to accommodate the threaded end of a suspension standard 64.

As shown the standard 54 is provided at its upper end with a laterally extending ,-hook 55 from which various forms of surgical appliances may be suspended for the convenience of the surgeon and his attendant.

Also in Figure-5 is suggested other uses of the standard 54.

As, for example, a heating pad, suggested by broken lines in Figure 5 and indicated by the reference numeral 56, may be suitably secured on the standard 54 as may also and if desired, associated with the heating pad 56 a thermometer 51.

Also, in accordance with the present invention, the board or base 6, preferably at the end thereof equipped with the rest 20, is equipped with an apertured lug 53 through which is trained a tourniquet tube 59.

Also, in accordance with the present invention, the board 5 at one edge thereof is provided with a notch 60 elongated longitudinally of the board, and between the ends of the notch there is secured to the board longitudinally spaced rings or annular bracket members 60 to accommodate a battery-equipped case 6| Such a'battery-equipped case Bl will be found advantageous when using the device in an ambulance, or in the field to provide a supply of electric current as may be needed. To that end the case 8| is provided at one end thereof with an electrical receptacle for receiving the plug on one end of an extension cord 62 as suggested in Figure 1, or the plug end of an electric cord 63 provided, for example, and as suggested in Figure 5, for the heating pad 56.

It will thus be seen that the splint may be readily equipped for almost any type of emer-'.

gency use, and may be equipped, in addition to what has been herein suggested, and as the use ,from the spirit of the invention as herein illustrated, described, and claimed.

Having thus described the invention what is claimed as new is: it

In a surgical splint of the class described, a splint board provided at one end thereof with a stationary rest having an inclined surface to support the arm at the back of the elbow joint, a second rest mounted on the board for longitudinal adjustment relative thereto and for accommodating the forearm at the hand, a rest for the elbow joint on the board'intermediate the firstnamed rest, and a clamp for engaging the arm at the elbow embodying a pair of clamping jaws disposed on the board atv opposite sides of the rest for the elbow joint and adjustable towards and away from one another transversely of the board, a restraining strap extending transversely of these-cond-named rest, and interengaging means on the respective opposite ends of the strap, and on opposite sides of the second-named rest for detachably securing the ends of said,

strap to the rest, and the jaws of said clamp provided on the upper edges thereof with loops, and an adjustable restraining strap trained through said loops and bridging the space between said clamping jaws; and said board adjacent one longitudinal edge thereof provided with a slot elongated longitudinally of the board to provide for the securing thereto a support for surgical appliances in a position of adjustment lengthwise of the board.
