Abstract

Abstract A neck x-ray protection shield includes a lead sheet secured within a synthetic foam pad member which is covered with a suitable cloth such as cotton. The lead sheet is selected of a length and width to provide a front and side neck enclosure. The pad member extends from the lead sheet, with suitable fasteners such as "Velcro" elements secured to the opposite ends. The unit is wrapped around the neck and the ends connected to form a collar resting on the patient's chest and with the collar in spaced relation to the neck portion for producing proper protective position in the presence of movement of the head, neck and shoulders of the patient. The foam pad defines a cushion support permitting the comfortable attachments of the shielding collar to the various sized patients.
