  • Publication number: 20220211974
    Abstract: A medical tube having improved lubricity is disclosed. The medical tube is produced by extruding a polymer material blended with a lubricity enhancing additive through a resilient die. The polymer material can be medical-grade high-density polyethylene, and the lubricity enhancing additive can be a silicone-based or alloy-based material. The medical tube can include one or more internal elongated protuberances so as to reduce the internal surface area of the medical tube available to generate friction on a guide wire inserted or withdrawn through the medical tube.

  • Patent number: 6405414
    Abstract: The clip of the present invention is a one-piece plastic clip having a plurality of substantially “C” shaped socket members, for example two, wherein the interior surface is not smooth. Rather, the interior is designed to enhance the grip on the protective tube. In one preferred embodiment, the interior surface has a plurality of spaced projections extending therefrom. Other textured surfaces can be used.

  • Patent number: 5263945
    Abstract: A female fitting for a Luer which comprises a hollow, cylindrical member having means to attach it to the Luer at one end thereof, and means for quickly and manually attaching a plastic tubing to the opposite end of the member. In order to attach the tubing, the interior surface of the fitting adjacent this end is provided with protuberances on the inside surface thereof which engage with the tubing as the tubing is thrust thereinto in order to provide a substantially mechanical lock by being impressed into the material of the tubing. The material of the tubing is softer and more impressionable than the material of the fitting itself and its protuberances. The protuberances are arranged in spaced relation on a spiral path.

  • Patent number: 4882948
    Abstract: A nutating cone transmission is characterized by a flexible speed control ring for controlling the rotational speed of the cone about its axis. The ring is mounted adjacent to the cone with a portion thereof in contact with and depressed by the surface of the cone. A displacement mechanism laterally displaces the ring relative to the cone while preventing rotational movement of the ring and slippage between the ring and the cone. The position of the ring relative to the diameter of the cone controls the rotational speed of the cone which is delivered to an output. The flexible speed control ring increases the reliability and efficiency of the transmission by eliminating slippage between the ring and damage to the cone through wear.
