United States Patent O CERVICAL COLLAR William L. Bartels, Portland, Oreg., assignor to Prosthetic & Orthopedic Supply Co., Portland, Oreg., a corporation of Oregon Application December 1, '1958, Serial No. 777,456

'3 Claims. (Cl. 12S-75) This invention relates to cervical collars, and more particularly to an improved cervical collar construction characterized by features which enable the collar firmly to support the head and neck portions of a wearer. Such collars are used in the treatment of strained or arthritic necks, the treatment of wry necks, and in other remedial applications, as for instance neck dislocations, etc.

A primary object of the invention is to provide an improved cervical collar construction which is light and easily worn, yet which gives maximum optimum support when placed in operative position about the neck of the user. As a result, the collar may be used to provide requisite support, without undue discomfort to the wearer.

More specifically, it is an object of the invention to provide a two-piece cervical collar construction which has a base portion for engaging the chest and upper shoulder portions of a wearer and a separate upper portion for engaging the head and Inaudible area of a wearer, wherein the normally relatively immobile portions of a wearer, that is, his or her chest, provides support for the collar through a chestand shoulder-engaging base piece which completely encircles the patients neck (and is thus relatively immobile during use), and wherein the normally .relatively mobile portions of the wearer, i.e., his or her head, is supported on a piece of lesser length which is fsecured at its ends during use in ixed position on the :neck-encircling piece. The construction reduces chances of chang and discomtiture, as motion tending to result from attempted head movement is not transmitted `directly to the larger, neck-encircling piece, but instead fis fabsorbed somewhat and resisted by the upper, head-saupgporting piece.

lAnother object of the invention is to provide such a fcervical collar which includes means for fixing in various fadjusted positions the relative position of the ends of the head-supporting piece, whereby maximum support after :adjustment is permitted each individual user. Any movefment permitted the head by the collar is limited substant'ially to one localized area, and movement here is perunitted only by reason of the flexible nature of the maiterial making up the base and upper portions ofthe xcollar.

Still ano-ther object of vthe invention is to provide a fcervical collar wherein a pair of primary support areas :are provided which have additional means making the :areas unyieldable, and wherein these support areas each have a base positioned substantially directly over the torward extremities of the clavicle of a wearer, and an upper end substantially directly under the lateral aspects of the mandible of a wearer.

These and other objects are attained by the invention, which is more fully described hereinbelow in conjunction with the accompanying drawings, wherein:

Fig. l is a plan View of an embodiment of the cervical collar of the invention, showing the collar laid out flat and before placement of the collar in operative position about a wearers neck;

ice

Fig. 2 is a section view of the cervical collar shown in Fig. 1, along the line 2 2 in Fig. 1;

Fig. 3 illustrates the collar in an operative position about a wearers neck (with the wearer in dotted outline); and

Fig. 4 illustrates a modication of the invention.

Referring now to the drawings, and more particularly to Figs. l and 2, 10 indicates generally a cervical collar of the type contemplated, comprising a pair of elongated sheet parts, designated at 11 and 12 respectively. Lower sheet part 11 has a longer Alength than upper sheet part 12, and constitutes a neck-encircling part in the device. When the collar is attached around the neck of a wearer, the left end in Fig. 1 of lower sheet part 11 overlaps slightly the right end of the sheet part. Upper sheet part 12, which constitutes a head-supporting part, does not fully encircle the neck when the collar is strapped in place but instead terminates in the vicinity of the neck near the base of a wearers ears.

Each of the sheet parts comprises a sheet-like body portion (11a and 12a) made of stiff but ilexible material. This material may take the form of a suitable plastic, which is semirigid in nature, but flexible when laid out in sheet form in a direction laterally of the Ifaces of the sheet. EXemplary of such plastic materials are the nylon plastics or the butyrate plastics. A stiftf rubber composition is also suitable, although such a composition might not be as attractive to wear due to its coloring.

The body portions of the sheet parts are covered over portions of their edges with a foam cushioning enclosed in a suitable covering. This cushioning is designated at 14 for lower sheet part 11 and 15 for upper sheet part 12.

Parts 11 and 12 are secured together at adjacent end portions by fixed pivot connections 31, 32, with the upper edge of lower part 11 overlapping the lower edge of upper part 12. Pivot connections 31, 32 take the form of rivets extending through both part layers. The pivot connections accommodate relative pivotal movement of the parts about axes normal to the plane of `the part faces. However, since the connections are iixed, i.e., are secured on both parts against any lateral shifting movement, they also hold the ends of parts 11 and 12 iirmly against lateral shifting. l

Intermediate pivot connections 31, `32 are a pair of elongated, substantially rigid adjustment mechanisms, indlcated generally at 36, 37. Each comprises an inner slide portion 3S and an outer slide portion 39.v v

Portions 38, 39 are maintained in an overlapped and an aligned position by a guide linger portion 41 integral with outer slide portion 39 which extends through and slides in a slot 42 formed in the inner slide portions. Guide linger portion 4 1 has projections 43 which underlie inner slide portion 38, and thus the guide finger is prevented from separating from portion 38. A screw 46 turned into an accommodating threaded bore provided in inner slide portion 38 and projecting outwardly through a slot 47 formed in outer slide portion 39 provides a means forxing `portions 38, 39 of the adjustment mechanism in various adjusted positions. A i

The upper and lower ends of each adjustment mechanism are pivotally secured, as by rivet connections 51, to upper and lower sheet parts 11, 12, respectively. The connections are made close to the outer edges of these parts and, like connections 31, 32, are also fixed against lateral shifting movement. The adjustment mechanisms perform the double function of fixing the relative vertical positioning and providing substantially unyielding support along those areas where they overlie parts 11, 12. The top and bottom ends are positioned in special locations, as discussed hereinbelow, where this rigid support is most desired.

In constructing the cervical colla, the ends of the longer, lower sheet part are brought together, slightly, before attachment by rivets 31, 32 to upper sheet part 12. Further, mechanisms 37, 38 are affixed to the sheet parts by rivets 51 with portions of the sheet parts disposed outwardly of the mechanisms lying fiat together. As a result, after parts 11 and 12 are assembled together, a bowed-out portion exists in the lower sheet part in the space between mechanisms 36, 37. Further, this bowedout portion ares outwardly, slightly, progressing from the top edge to the bottom edge of the part. This bowedout, ared portion is best illustrated in Fig. 2.

The collar is secured about the neck of a wearer by bringing together the outer ends of lower sheet part 11 until a snap buckle 56 carried by a strap 57 secured to one end of the part overlies a snap fastener secured to the other end of the sheet part, and then snapping the buckle portion to the snap fastener. The snap buckle is adjustable longitudinally along strap S7 to enable the collar to be used with different neck sizes.

It will be noted that the lower sheet part terminates in elongated end portions 61, 62, which have substantially linear and parallel upper edges indicated at 66, 67 for end portion 61 and at 68, 69 for end portion 62. When the collar is secured in place, the lower edges engage the base of a wearers neck and the upper edges provide occipital support. This support is a relatively steady and immobile type of support, due to the `fact that the lower part constitutes the neck-encircling portion of the device and when in operative position rests on the more stable chest and shoulder portions of a wearer.

The collar is positioned about the neck of a wearer, as shown in Fig. 3. When the collar ends are turned over, tiexing of the collar has the eiiect of moving the center portion of part 11 atly against the center of part 12, since in bending the collar the lower part is curved over a greater radius than the upper part. In operative position, the iiared-out edge of part 11 curves downwardly and rests on an area located over the forward extremities of a patients clavicle, designated generally at 71.

It will be seen that in certain areas the collar of this invention is relatively rigid, when the collar is in operative position. These areas are along the end portions 61, 62 of the collar, past connections 31, 32, up to where adjuster mechanisms 36, 37 are located. From pivot connections 31, 32 to where mechanisms 36, 37 are located, a rigid, triangular-shaped brace structure exists.

An important feature of the invention is the position of the ends of elongated brace mechanisms 36, 37. The bottom ends of mechanisms 36, 37 are closer together than the top ends. Referring to Fig. 3, when the collar is placed about a Wearers neck, the bottom ends of meci anisms 36, 37 are located substantially directly above the forward extremities of the clavicle. The upper ends of the adjuster mechanisms, on the other hand, are located directly under the lateral aspects of the mandible of the wearer. Thus the most rigid support is provided between these locations, which is where such support is most desirable.

Fig. 4 shows a modification of the invention. In this figure, an auxiliary adjustable mechanism 76, similar in construction to mechanisms 36, 37, is provided between mechanisms 36, 37. This may be desirable in some instance when additional support is needed at center portions of the collar.

The cervical collar of the invention is relatively economical to produce, as relatively few parts are needed in the construction and these parts are readily assembled. A few principal collar sizes may be adjusted to fit many different neck sizes. Thus, the collar may be made in a few principal sizes and then kept in stock by a seller for sale to patients of all sizes.

While speciiic embodiments of the invention have been described herein with particularity, it is appreciated that various changes may be made in the conguration and arrangement of the various parts without departing from the invention. It is desired not to be limited to the speciic embodiments shown. As included in the invention, all are modifications coming within the scope of the appended claims.
