Abstract: The present invention is directed to a self-contained, totally disposable apparatus for the collection and reinfusion of blood which is suitable for use with a chest drainage unit to provide for the autotranfusion of autologous blood and the method of using the apparatus. The blood collection and reinfusion apparatus is separate in structure from the chest drainage unit and comprises a rigid outer container and an inner flexible container in conjunction with portals for blood collection, reinfusion, and attachment to a vacuum source. The apparatus and method of the invention provides a closed system, requires minimal handling of the blood, and provides for greater patient safety in that no interruption of the operation of the chest drainage unit is required.

Abstract: Image display apparatus reads data from an image memory to produce an image on a interlaced raster-scanned display. The image can be zoomed by producing X and Y magnifications. X magnification is produced by repeating each pixel a predetermined number of times. Y magnification is produced by repeating each display line a predetermined number of times. The number of repetitions of each display line can be varied from line to line and can be different in the two frames, so as to cope with odd-number Y magnification factors. This is achieved by using a register file which holds the required line repetition counts.

Abstract: A method and apparatus for filling an underwater drainage device is provided with a rotatable funnel and cap which is positioned between the manometer chamber and water seal chamber in a pleural drainage device. In use the cap may be removed and the funnel positioned to fill the manometer chamber to the desired level and the funnel may then be rotated to fill the underwater seal chamber to the desired level. A positive pressure relief valve is provided in the cap.
