Abstract: A heart/lung machine base reduces tubing length by reducing the distance between the arterial pump and the surgical table. This is accomplished by providing a lift which will raise and lower the base in order to follow the movement of the surgical table. In this manner, slack in the tubing is unnecessary. Also, the cardioplegia pump can be positioned on an upper shelf in a relatively close position to the oxygenator. Tubing to the cardioplegia pump can therefore be reduced. To further minimize tubing length, the disposables can be configured in a generally straight line between the arterial pump and the patient. In order to maintain access and visibility of the vent and sucker pumps which are located beneath the cardioplegia shelf, an incline platform is provided. The arterial pump is positioned outwardly of uprights of the base such that its access and visibility is unhindered. Because of a mirror-image configuration for the base, it can readily be used in either a right-sided or left-sided configuration.

Abstract: A pre-assembled array of corner shelves is fastened together by three flexible lines threaded through apertures in the shelves so that they can hang downwardly from a single hook mounted in the corner between two intersecting walls. The lines are so disposed to form an acute angle with the corner line toward the frontmost edge of the shelf disposed in the corner, thereby to force the shelf against the corner and adjacent walls by its own weight and that of objects on it to support the structure and prevent it from slipping or sliding. The spacing may be rearranged simply by moving the lines and the shelves may be readily leveled in the same manner. The shelf array is simply removed for cleaning walls or the shelves without loosening any mounting hardware.
