BACKGROUND OF THE INVENTION
1. Field of the Invention
The Brace is a device for immobilizing the chin of a patient requiring medical treatment. As such this invention relates to the filed of medical and dental apparatuses used to restrict patient movement where such movement would be risky or counterproductive to the procedure or procedure which the patient will be undergoing.
2 . Description of Related Art
Braces are known in the art which support the chin rigidly to a chest harness of other reference point. Typically these devices provide for one degree of freedom in the adjustment of the distance from the patient's chest to the patient's chin. Utility U.S. Pat. No. 3,724,452 to Nitschke, U.S. Pat. No. 7,549,970 to Tweardy, U.S. Pat. Nos. 6,267,741 and 6,368,295 to Lerman, and U.S. Pat. No. 5,054,475 to Calabrese et al are typical of this class of brace. It is an object of the present invention to provide additional degrees of freedom in the adjustment of the patient's chin relative to the said patient's chest.
Braces are also known in the art which support the chin rigidly relative to the body by providing a head restraint which is rigidly fixed to a harness attached at the patient's back. Utility U.S. Pat. No. 5,409,450 to Donelson, U.S. Pat. No. 7,549,970 to Tweardy, U.S. Pat. Nos. 6,267,741 and 6,368,295 to Lerman, and U.S. Pat. No. 5,054,475 to Calabrese et al are typical of this class of brace. It is the object of this invention to provide a brace which can be used by a patient while sitting in a chair.
BRIEF SUMMARY OF THE INVENTION
The brace comprises: a chest plate; a chin support for supporting a Patient's chin in a fixed position relative to said Patient's chest; a rod having a top surface, said rod adjustably attached to said chest plate; and an adjustable linkage connected to said top surface and to said chin support. The brace is used to immobilize a Patient's chin relative to The Patient's spinal column, or The Patient's chest, or both when said Patient's chin is placed upon the chin support.

DETAILED DESCRIPTION OF THE INVENTION
The brace 1 comprises: a chest plate 2; a chin support for supporting a Patient's chin 4 in a fixed position relative to said Patient's chest; a rod 7 having a top surface 8, said rod 7 adjustably attached to said chest plate 2; and an adjustable linkage 15 connected to said top surface 8 and to said chin support. The brace 1 is used to immobilize a Patient's chin 4 relative to The Patient's The Patient's chest when said Patient's chin 4 is placed upon the chin support.
The chest plate 2 is a base formed to fit comfortably against The Patient's chest and is formed of any plastic, metal, or other material having sufficient strength to support the chin support when used to immobilize said Patient's chin 4. The chest plate 2 is also provided with a left shoulder brace 10 and a right shoulder brace 11. Each shoulder brace is provided with one or more adjustable straps 12 attached to the bottom portion of the chest plate 2. The shoulder braces and straps secure the chest plate 2 to the Patient's chest. It is appreciated that additional braces and straps are contemplated as within the present invention.
The chin support is a metal or plastic frame which includes a post 13 attached to an adjustable linkage 9 and a pad 14. In another embodiment the adjustable linkage 15 includes a post 13 attached to the chin support. In both embodiments the post 13 may be threaded to match a threaded hole to achieve the desired connection. Alternatively, the post may be attached to the chin support or post 13 by welding or by a suitable adhesive. When in use the pad 14 is placed in contact with the Patient's chin 4.
The rod 7 has a top surface 8 attached to the adjustable linkage 15 and is slideably attached, and may be rotatably attached, to the chest plate 2 to permit adjustment of the position of the chin support relative to the Patient's chest. The rod 7 is of any desired cross section but a circular cross section facilitates rotational attachment to the chest plate 2.
The adjustable linkage 15 connects the chin support to the top surface 8 of the rod 7. The adjustable linkage 15 permits adjustment of the chin support relative to the chest plate 2 and the ability to lock the chin support in a selected position relative to the rod 7. The dual ball joint 15 shown in figure 4 is one such adjustable linkage 15. The dual ball joint 9 includes two curved plates 19 and one locking screw 20. The dual ball joint 9 is completely adjustable before it is fixed in place by the locking mechanism 20 and this allows for aligning the chin rest under the patient's chin in dimensions thus allowing for adaptation to different anatomies and symmetries of different patient's jaws.
In use the chest plate 2 is fastened by means of the left shoulder brace 10, right shoulder brace 11, and adjustable straps 12 to The Patient's chest and the rod 7 is adjusted to place the chin support at a selected height relative to the Patient's chest by an adjustable connector 18 connecting the rod 7 to the chest plate 2. Then the technician places the chin support at a desired location and the Patient's chin 4 is placed in contact with the chin support. The adjustable linkage 15 is then locked and the Patient's chin 4 is thereby immobilized.
