Abstract
Abstract A cervical collar is made of plastic foam and includes a thin band of resilient plastic material biasing the foam into an annular shape terminating in opposed rear ends which may be separated to circumferentially expand the collar against the bias of the band for fitting about a patient's neck. A front central top portion of the collar includes a depression and the top surface itself is beveled and shaped in such a manner as to comfortably cradle a patient's front jaw portion and side areas of the head. An outer covering of fabric material may be applied about the collar for purposes of cleanliness and enhancement of the aesthetic appearance of the collar.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
126 words
A cervical collar comprising, in combination: a. a plastic foam member curved into an annular shape with its ends terminating in the rear in spaced opposed relationship; and, b. at least one band of resilient plastic material different from said plastic foam biased into a desired annular shape with its ends terminating in spaced opposed relationship secured to said foam member to hold the foam member in its annular configuration, said annular configuration being circumferentially expandable against the bias of said band by increasing the separation space of its ends so that the foam member will fit snugly about a person's neck, the upper front portion of said member including a front depression for receiving and comfortably cradling the forward under portion of a patient's jaw.
Claim 2
Dependent Claim
126 words
A cervical collar comprising, in combination: a. a plastic foam member curved into an annular shape with its ends terminating in the rear in spaced opposed relationship; and, b. at least one band of resilient plastic material different from said plastic foam biased into a desired annular shape with its ends terminating in spaced opposed relationship secured to said foam member to hold the foam member in its annular configuration, said annular configuration being circumferentially expandable against the bias of said band by increasing the separation space of its ends so that the foam member will fit snugly about a person's neck, the upper front portion of said member including a front depression for receiving and comfortably cradling the forward under portion of a patient's jaw.
Claim 3
Dependent Claim
24 words
A collar according to claim 1, in which said band is secured to and disposed about the inside surface of said plastic foam member.
Claim 4
Dependent Claim
68 words
A collar according to claim 2, including an additional band of resilient plastic material different from said plastic foam biased into an annular shape larger than the annular shape of said first mentioned band with its ends in spaced opposed relationship and secured to and disposed about the outside surface of said plastic foam member, said member being circumferentially expandable against the bias of both of said bands.
Claim 5
Dependent Claim
24 words
A collar according to claim 1, in which said band is secured to and disposed about the outside surface of said plastic foam member.
Claim 6
Dependent Claim
98 words
A collar according to claim 1, in which the top surface of said plastic foam member is beveled radially inwardly and downwardly with its top surface sloping downwardly from opposite side portions toward said front depression so that the vertical distance between the top and bottom surfaces of the collar decreases from the sides towards the front whereby rearward extended portions of a patient's jaw towards his ears are cradled by the top surface of said collar and such cradling takes place for patients with both short and long necks so that the collar is universal in use.
Claim 7
Dependent Claim
53 words
A collar according to claim 5, in which the thickness of said plastic foam member gradually decreases from the sides towards the front so as to provide greater resiliency in the front area to accommodate emergency head movement but still tend to hold the patient's head in a straightforward position under normal use.
Claim 8
Dependent Claim
62 words
A cervical collar according to claim 1, including a removable sock like stretchable fabric material arranged to be fitted over one of the rear ends of said plastic foam member to completely enclose the member, said fabric material being of a color and design to enhance the aesthetic appearance of said collar and being removable for washing and replaceable on said collar.
