    摘要: A particle filled neck brace is used for immobilizing the neck and chin of a patient and includes a vacuum pump disposed on the neck brace, which pump is communicated to the interior of the neck brace. After the neck brace is secured around the neck and chin of the patient, the vacuum pump is manipulated to remove air from the neck brace to form a rigid mold about the patient's neck and chin. The vacuum pump has a one way directional valve so that the neck brace remains in a rigid configuration for as long as the neck brace is applied to the patient. The neck brace also specifically forms a rigid mold over the patient's chin so as to immobilize the patient as well as to provide a comfortable fit without inducing further distracting the patient or restricting the patient's venous return blood flow.
