  • Display panel and controls for blood mixture delivery system
    Patent number: 5573502
    Abstract: A display panel for use with a blood mixture fluid delivery system, which system has mechanisms for infusing blood mixture fluid to a patient and for controlling characteristics of the fluid delivery system. The display panel includes a visible schematic representation of a blood mixture fluid flow path through the fluid delivery system and visible displays of two or more of the controllable characteristics of the fluid delivery system, which visible displays are positioned along the schematic representation of the blood mixture fluid flow path.

  • IV Delivery controller
    Patent number: 4553958
    Abstract: A controller (34) is disclosed for use with a dual delivery system including a primary fluid container (12) and a secondary fluid container (14). The display (48) on the controller (34) presents a representation of the primary and secondary containers and prompts the operator to input the desired primary and secondary fluid flow rates and primary and secondary fluid volumes to be infused. During operation of the controller, a series of flow lines displays (118, 126, 144) represent motion of fluid from the container being drained to indicate to the operator which fluid is being infused. An alarm will be sounded upon the detection of an occlusion within the flow lines, the presence of air within the flow lines or an open door on the controller. During the flow from a particular container, the displays associated with the other container are deactivated to prevent confusion to the operator.

  • Watch having positioned controlled display actuator
    Patent number: 3955356
    Abstract: Disclosed is a solid state watch having an electro optical display which is selectively actuated by a gravity switch contained in the watch casing and positioned such that upon a displacement from a horizontal of the watch the display is actuated. A preferred embodiment utilizes a triangular-shaped cavity having a ball-shaped conductor movably contained therein for engaging a pair of electrical contacts within the cavity for coupling power to the display. Furthermore, the displacement of the watch from horizontal must also be within a selected orientation range.
