Abstract
A cervical collar which is made of a pad of resilient foam material with a scalloped depressed area at the middle of the inside surface of the collar whereby a user's chin is supported in the depression and pressure on a user's throat area is relieved by the reduced thickness provided by the depression.
Claims5
A cervical collar for placement around a user's neck, comprising:
- an elongated pad of resilient foam material generally rectangular in cross-sectional configuration having two end portions, an inner surface for placement adjacent a user's neck, an outer surface, a top edge surface and a bottom edge surface, the distance between said top and bottom edge surfaces being substantially constant along the length of said pad;
- means at said end portions for detachably fastening said end portions together with said pad about the user's neck;
- said pad having a depressed area in said inner surface at the longitudinal mid-portion of said pad extending from and including said top edge surface toward said bottom edge surface for the greater portion of the distance between said top and bottom edge surfaces, said depressed area being generally parabolic in outline with its apex toward said bottom edge surface;
- and,
- said inner surface within said depressed area being generally concave in form with the deepest portion of said depressed area being at said top edge surface generally at the longitudinal mid-point of said depressed area and with said depressed area decreasing in depth in either longitudinal direction from the longitudinal mid-point of said depressed area and decreasing in depth toward said bottom edge surface whereby, with the mid-portion of said top edge surface located underneath the user's chin, said depressed area acts to lessen pressure in the user's throat area.
