Abstract: A catheterization system for treatment of patients can include a peripherally inserted central catheter comprising a catheter tube joined to an extension leg with a junction and a securement device that fits around a portion of the junction to inhibit movement. The catheter tube can include a taper proximate the junction, the taper transitioning the catheter tube from a larger outer diameter and a larger wall thickness to a smaller outer diameter and a smaller wall thickness. The taper and thicker wall thickness near the junction can help prevent damage to the catheter tube near the junction when bent (e.g., to secure a proximal region of the catheter to a patient's arm). The securement device can configured to fit around an outer diameter of the junction to inhibit movement of the junction when the junction is held in the securement device.

This enables uniform charging across the width of the photoreceptor. The present invention fills and pressurizes a porous tube with a liquid. The liquid evenly exudes from the pores along the entire length of the porous tube. A hydrophilic liquid retentive foam which contacts the photoreceptor surface is wrapped snugly around the tube. The conductivity and overall rate of dispensation of liquid is controlled by the pressure differential across the porous tube.

Abstract: An apparatus for fusing images to a sheet. A fuser device is provided using a transparent fusing roll having an internal heating device which focuses the energy to a narrow area of the roll adjacent the nip formed with a pressure roll. A transparent fuser roll is used in a pressure nip fusing system to take advantage of the quick response of a focused lamp system while at the same time yielding the desirable image quality attributes of the pressure nip in two roll fusing. The focused lamp is completely enclosed and the heated region of the paper is within the nip contact region so there exists no possibility of igniting the paper. A lateral temperature smoothing device, or leveling roll, is also provided to maintain a fairly uniform temperature axially across the fuser roll. This is particularly useful for a wide fuser roll, i.e., 17 inches, through which narrower paper, i.e., 11 or 14 inches, is passing to prevent the ends of the fuser roll which do not contact the paper from overheating.
