Embodiment Construction

[0029] Although the invention is shown and described herein with reference to particular embodiments, the invention is not intended to be limited to the details shown. Rather, various modifications may be made in details within the scope and range of equivalents of the claims, without departing from the scope of the present invention.

[0030] The present invention solves the above problems and provides a head and mouth securing device for securing a thermoplastic mask to a patient and securing the patient's head. It includes a low melting temperature thermoplastic mask and a bite piece having a mouth receiving end for securing a patient's mouth. The mouth-receiving end of the bite is inserted from the outside (non-patient side, distal surface) of the thermoplastic mask and pushes a portion of the mask into the patient's mouth.

[0031] Referring generally to the drawings, the present invention provides preforms, such as preforms 10, 20 and 1200, for anchors formed with bite ...

Abstract

Methods of immobilizing the head of a patient include heating a thermoplastic mask preform to a formable temperature, forming the thermoplastic mask over at least a mouth of the patient, and pushing a mouth receiving end of a bite piece into a portion of the thermoplastic mask preform that is positioned over the mouth of the patient, which moves the portion of the thermoplastic mask preform into the mouth of the patient. The methods also include allowing the thermoplastic mask preform to cool from the formable temperature, causing the portion of the thermoplastic mask moved into the mouth of the patient to harden.

Description

[0001] Cross References to Related Applications [0002] This application is related to and claims priority to U.S. Provisional Application No. 61 / 827,777, filed May 28, 2013, entitled HEADANDJAWIMMOBILIZATIONDEVICE, and U.S. Provisional Application No. 61 / 903,631, filed November 13, 2013, entitled HEADANDJAWIMMOBILIZATIONDEVICE interests, the contents of both applications are hereby incorporated by reference in their entirety for all purposes. technical field [0003] The present invention relates to patient immobilization for radiation therapy and other uses. Background technique [0004] Immobilization of the patient's head is critical in various diagnostic and precise treatment procedures of the patient's head and neck region. Low melting temperature thermoplastic face shields are often used to immobilize patients. To limit patient movement, thermoplastic materials are usually softened in a warm water bath. The mask is then stretched over the patient's head. As the t...
