  • Patent number: 4221288
    Abstract: A roller of the slip-type is comprised of a sleeve with an insert press fitted therein. The other end of the insert houses a bearing assembly, the inner and outer race of which are respectively keyed to a stationary support axle and to the insert. A driven element is loosely mounted about the insert but is pressed against the insert by a belt under tension which also engages one or more driven elements of adjacent rollers. The driven element is driven by an endless driving devices. When a counter-torque is experienced by the roller due to an impediment which is greater than the driving torque, slippage will occur between the driven element and the insert, and the article being carried by the conveyor will come to rest.

  • Patent number: 4219022
    Abstract: Equipment sets for the sequential administration of medical liquids wherein a primary liquid can be administered at a flow rate independent of the flow rate of a secondary liquid and prevent the inadvertent administration of air when the secondary liquid is depleted. The sets of this invention employ parallel flowpaths for the secondary liquid and a single liquid sequencing valve to control the flow of the primary liquid and the secondary liquid in one of the parallel flowpaths.

  • Patent number: 4182756
    Abstract: High calorie solutions of low molecular weight glucose polymer mixtures useful for intravenous administration, preferably via a peripheral vein, are disclosed. Methods of preparing the solutions and their preferred rate of infusion at less than 5 mg./min./kg. of patient body weight are also disclosed. The solutions can be isotonic to human blood at 20-50% W/V as the glucose polymer mixtures have an average degree of polymerization ranging from 4 to 10. At the preferred rate of infusion high utilization of the glucose polymers infused occurs in human patients, including diabetics. The utilization can be further enhanced by concomitant injections of insulin. The solutions can be administered concomitantly with amino acids, lipid emulsions, vitamins and electrolytes.

  • Patent number: 4160451
    Abstract: A unidirectional, needle outside, reel-type catheter placement unit is disclosed. The unidirectional unit obviates severing of the catheter by the needle, which can occur when the catheter is retracted in bidirectional units. Preferably, the catheter placement unit comprises an overcap or cover which is only coupled to the reel of the reel-type catheter placement unit by a ball clutch when the overcap is rotated in a direction that advances the catheter from the unit.

  • Patent number: 4158362
    Abstract: A unidirectionally valved drip chamber, inlet port assembly useful for liquid collection containers, e.g., urinary collection bags, or other containers requiring antireflux protection is disclosed. The assembly comprises a flexible, hollow, substantially frusto-conical unidirectional valve fixedly mounted between the inlet and outlet of the assembly. The valve has a closed top and open bottom and is normally closed against a complementary substantially frusto-conical valve seat. The conical wall of the valve flexes away from the valve seat to allow liquid to flow from the inlet to the outlet. Liquid flowing from the outlet towards the inlet forces the valve more firmly against the valve seat so that the valve remains closed to such reverse or reflux flow.

  • Patent number: 4130622
    Abstract: A self-supporting tubular filter including a sleeve of filter material and a frame formed by longitudinal and circumferential ribs attached to the sleeve. The filter is characterized by a longitudinal separation along a substantial length of the sleeve which is spliced together by one of the longitudinal ribs. That rib extends through the separation so that it overlies and is attached to the interior and exterior surfaces of the sleeve adjacent to the separation. Also disclosed are the use of the filter as a microemboli blood filter and a method of its manufacture employing a single male core pin with first and second female molds.
