Abstract: The present invention comprises a medication delivery system for administering an infusion therapy using a medication delivery pump and related fluid container. Medications in a flexible bag of the container are expelled from the bag by the pump into an administration set and delivered to an infusion site. The administration set limits the rate at which a spring compresses the bag. The system provides improved infusion therapy administration which is particularly advantageous for reducing errors, infections and other complications associated with manual infusion techniques.

Abstract: The present invention comprises a medication delivery pump that is configured to administer an infusion therapy using a medication delivery container. Medications in a flexible bag are expelled from the bag and delivered to an infusion site. A fluid delivery pump of the invention may have a constant force spring and a mechanical timer. The constant force spring is configured to compress a flexible fluid container. The mechanical timer assembly is coupled to the constant force spring and limits the maximum rate at which the spring compresses the fluid container. The pump may include first and second doors for charging the spring. Opening the first pump door partially charges the constant force spring and opening the second pump door fully charges the constant force spring. The pump provides improved administration of infusion therapy which is particularly advantageous for reducing errors, infections and other complications associated with manual infusion techniques.

Abstract: An SIMD array processor having a scalable and flexible architecture. The SIMD array architecture includes an array of processing elements, a plurality of processor controllers, and at least one other computer system. A system area network interconnects at least one user computer with the processor controllers and the computer system; and, a storage area network interconnects at least one storage device with the processor controllers and the computer system. The SIMD array architecture is adapted to allow different user computers to use different portions of the array of processing elements and/or different processor controllers and computer systems simultaneously. The array of processing elements has a hierarchical structure comprising backplanes, PCB's, ASIC's, and arrays of processing elements. The SIMD array architecture can be scaled by increasing the quantity of backplanes, PCB's, ASIC's, and/or by increasing the size of the arrays of processing elements.

Abstract: In accordance with the present invention, there is provided a medication delivery container that is preconfigured to administer an infusion therapy upon activation by a pump mechanism. The configuration of the bag can determine the sequence and amount of medication to be delivered. In one embodiment of the invention, the medication delivery container includes a multi-chamber bag, a manifold assembly and an administration set. The manifold assembly is configured with internal conduits and valves to direct output from each chamber of the bag to an output port in the manifold, and into the administration set. In additional embodiments, there are provided structures in the container to alleviate pressure drop during the application of pressure to the container. Invention containers provide improved infusion therapy administration which is particularly advantageous for reducing errors, infections and other complications associated with manual infusion techniques.

Abstract: A bone cement mixing apparatus is provided for mixing solid and liquid bone cement components. The apparatus includes a common receptacle base having an interior base surrounded by a continuous side wall with an access opening for accessing the interior. A lid is provided for forming a closure over the top of the receptacle base, the lid having a smaller access opening therethrough. A pair of modular inserts can be selectively placed within the interior of the common receptacle base. The modular components include a mixing bowl and a mixing syringe. Thus, the user can place the bowl or syringe as desired within the receptacle base before mixing bone cement therein. Impellers are provided for each of the mixing vessels including the bowl and the syringe. A vacuum line is provided for sectioning air and gases from the interior of the receptacle base during an addition of liquid or solid bone cement components to either the bowl or the syringe via the smaller access opening in the lid.

Abstract: An apparatus provides a user-adjustable viewing angle for a cathode ray tube (CRT) display. The CRT may be rotated in either of two directions by depressing a control bar located along the front bezel of the display. Once set to the desired position, the control bar is released and the CRT is inhibited from rotating in both directions. Thus, the CRT may be locked in a variety of positions to suit the particular user or environmental conditions.
