ABSTRACT:
An improved sterile container is disclosed for receiving and enclosing an unsterile x-ray cassette holder so as to avoid contamination of a sterile operative field by the unsterile x-ray cassette holder when the cassette holder is being used to take x-rays during surgery in a sterile operative field.
The improved container includes sterile fastening means for properly positioning the x-ray cassette holder with respect to the patient to be x-rayed so as to obtain optimal x-ray views without unnecessarily exposing any operating room personnel to the x-rays and so as to minimize the chances that the x-ray cassette holder will slip or otherwise move, with respect to the patient, during the time the x-rays are being taken. The sterile fastening means serves both to properly position the x-ray cassette holder with respect to the patient and to properly position and maintain the position of the patient to be x-rayed with respect to the x-ray cassette, both without the need for operating room personnel to hold the container or the cassette holder during exposure of the x-ray film. The sterile fastening means, in one preferred embodiment of the invention, comprises a sterile adhesive tape which permits the sterile container having the unsterile x-ray cassette holder therein to be secured to the portion of the patient to be x-rayed without danger of the container moving or being moved, relative to the patient, during the time that the x-ray film is being exposed.
