Abstract: A portable, padded chair made from X-ray transparent materials is used to comfortably support a patient while taking X-rays for medical diagnostic purposes. The use of X-ray transparent materials reduces the medical assistant's and patient's risk of repeated exposure to unnecessary X-ray levels. Also, the chair allows a patient to remain in a sitting or reclining position while X-rays are taken. A foot pedal and locking wheels allow for easy adjustment of the chair so that the patient is positioned comfortably and securely. A bucky tray, adjustable along the length and width of the chair, and a piano stand fixture, that attaches to the arms of the chair, are used to hold X-ray film cassettes. Additionally, the arm supports are adjustable and capable of being dropped to the side of the chair so a patient is easily transferred to and from a hospital bed.

Abstract: Improvements for a positioner for a child being X-rayed are disclosed. The improvements include an improved latch for securing the carriage that supports the X-ray film cassette in a positioner for a child being X-rayed at a position after the carriage is adjusted upwards or downwards; and, the addition of resilient pads for increasing the friction between glide strips and foot members of a positioner for a child being X-rayed so that the foot members will be more effectively secured to the glide strips. The improvements also include an improved latching mechanism used in securing the film holder of the positioner for a child being X-rayed in a position as it is moved towards or away from the upstanding members that secure the child. The buttons that are used to secure the foot members to the glide strip have also been improved by providing them with a tapered bottom surface. The taper compensates for variable thickness in the foot member.

Abstract: The device is a diagnostic tool for the determination of the functional loss of the collateral ligaments of the elbow. The device serves to position and to stabilize the arm of a subject and to position the elbow in a predetermined fixed position to allow for X-raying of elbow joints under graded pressure. A first part of the device is a unit for receiving a hand and securing the wrist in a predetermined position. The hand receiving member has a planar upright support section which has a plurality of spaced holes. Preferably, the spaced holes are arranged in a plurality of parallel rows. The first part includes a first rod shaped member or roller positioned in a hole such that it is contacted by the palm of the hand, with the palm upward in supination. The wrist is secured to a second rod or roller mounted in another of the holes, to hold the wrist in a predetermined position relative to the second roller.

Abstract: A portable x-ray cassette holder apparatus includes a flat radiolucent patient supporting surface having a flat base surface and a patient supporting surface. The flat base surface is spaced a predetermined spaced distance from the patient supporting surface with spacer members. An x-ray cassette holding portion holds an x-ray cassette between the patient supporting surface and the flat base for holding the cassette loaded with film in predetermined position. An x-ray cassette guide utilizes the spacing members for guiding the x-ray cassette into the x-ray cassette holder where the x-ray cassette is held in position during the taking of an x-ray. A patient gripping member handle is removably attached to the patient supporting surface in a predetermined position and extending substantially perpendicular therefrom for gripping by a patient during the taking of an x-ray in a sitting position.

Abstract: A flat top radiographic table includes a pair of longitudinal frame members which grip a thin panel at opposite ends thereof. The longitudinal frame members grip the thin panel at its bottom and side edges only, with the panel being free of support of the frame members at the panel top. The table top is thereby made coplanar to simplify transfer of a patient to and from the table. The frame members preferably grip the panel via a pair of projections which mate with a pair of recesses on the side edges and bottom of the thin panel.

Abstract: A wheelchair X-ray radiograph apparatus and method is disclosed for taking a radiograph of a patient in a wheelchair from almost every medically required position. This apparatus includes a modified wheelchair with detachable armrests and backrests, and a radiograph accessory consisting of a radiograph film cassette holder and an opposed brace member attachable to the modified wheelchair utilizing the same mounting used by the detachable armrests and backrests. The apparatus allows the taking of anterior-posterior, posterior-anterior, right and left lateral and skull and cervical spine radiographs of a wheelchair confined patient or trauma patient.

Abstract: A cassette holder is provided for use with a wheeled stretcher or the like. The holder is slidably and pivotably mounted to a pair of support tubes positioned beneath the top board of the stretcher. It may accordingly be positioned beneath any portion of the top board which is desired. To replace an x-ray or other type of film cassette, the holder may be pivoted downwardly towards either side of the stretcher. A tray slides out from the holder to provide easy access to the cassette. The holder accepts cassettes from both sides of the stretcher depending upon which support tube is utilized as a pivot axis.

Abstract: Restraint apparatus is provided for immobilizing a pediatric patient during exposure of X-ray film, particularly in connection with chest examinations. The invention permits considerable reduction in the extent of exposure area of the patient's body. Manual restraint is not required and hence non-patient exposure to radiation is avoided. Because movement is restrained, the need to re-expose the patient is virtually eliminated. Adjustment is provided for the comfortable accommodation of infants up to small children. The apparatus secures both arms of an infant or small child in a forward and upward extension to achieve proper anatomical positioning for anterior-posterior or lateral chest X-ray study. Adjustable holders for different size film cassettes form part of the apparatus.
