    摘要: The cross section of a curved portion of a curved cannula is oval shaped. The oval is oriented such that a major axis of the oval is generally aligned with the curved portion's bend radius. In one aspect, the cannula tube is ovalized so that the radius of curvature of an interior wall approaches the outer radius of an instrument component that contacts the curved portion during instrument insertion. In this first aspect, a wider contact patch area between the instrument component and the cannula results, which reduces friction and stick-slip during insertion. In another aspect, the cannula tube is ovalized so that the radius of curvature of an interior wall is less than the outer radius of an instrument component that contacts the curved portion during instrument insertion. In this second aspect, two contact patches are established between the instrument component and cannula, which also reduces friction and stick-slip during instrument insertion. Also disclosed is a cannula orientation marking that changes circumferential orientation along a length the curved cannula to help a person who is inserting the cannula to properly twist the cannula during insertion.

    摘要: Devices and methods for attaching a belt cartridge to a belt drive platform. A clip attached to the belt is inserted into a slot in the drive spool of the belt drive platform. The cover plate of the belt cartridge fits into a channel beam in the housing of the belt drive platform, thereby securing the cartridge to the housing. Belt guards, for protecting the cartridge, belt drive platform, patient and rescuer, are rotatably attached to the cover plate and are secured around spindles disposed on the sides of the housing.
