Abstract: A peripheral catheter having a catheter tip diffuser for reducing an exit velocity of an infusant within the catheter. Pluralities of diffusion side holes are provided on the tip portion of the catheter. Some examples further include pluralities of annularly arranged, staggered diffusion holes provided on the tip portion of an intravenous catheter to streamline infusant issued from the diffusion holes. An inner surface of each diffusion hole is further angled relative to the inner surface of the catheter lumen such that an infusant within the lumen exits the catheter though the diffusion holes at an angle less than 90°.

Abstract: A catheter having a catheter body with a lumen and a distal lumen opening. The catheter's lumen extends through the catheter body along a longitudinal axis of the catheter body. A hole is formed through a wall of a distal portion of the catheter body. A portion of the proximal surface of the hole is inclined at an acute angle with respect to the longitudinal axis of the catheter body. The acute angle of the proximal hole surface opens proximally with respect to the catheter body.

Abstract: Peripheral catheters having diffusion holes can be reinforced by embedding stripe material within the material of the catheter tube body. The stripe material can be embedded using a coextrusion process. The stripe material may consist of one or more stripes which may be arranged in a straight or non-linear pattern such as a helical pattern. The diffusion holes can be positioned between adjacent stripes or between adjacent portions of a single stripe. The diffusion holes can be formed after the stripe material has been embedded. A lubricant may be applied to a peripheral catheter that includes stripe material and diffusion holes.

Abstract: An intravenous system can be optimized to improve blood draw success and reduce hemolysis within the blood sample. Multiple optimizations can be made to an intravenous system, such as a peripheral intravenous catheter, to enhance the system's ability to provide blood samples having sufficient quality for many different tests. These optimizations can include features which enable an intravenous system, such as a peripheral intravenous catheter, to continue to perform efficiently when used to obtain blood samples even after the system has been placed within the patient's vasculature for a substantial duration of time. Also, these optimizations can include features for optimizing the fluid path and flow characteristics during blood withdrawal to minimize the amount of hemolysis that may be caused during withdrawal. Further, these optimizations can include features for integrating blood acquisition and dispense capabilities within the system.

Abstract: An auto-occlusion safety device is provided for use in preventing rupture of infusion components during rapid infusion procedures. An occlusion valve is disclosed having a threshold pressure that is less than a rupture tolerance of the infusion system components. As the fluid pressure of the infusion system increases beyond the threshold pressure of the occlusion valve, the occlusion valve is automatically activated thereby occluding fluid flow upstream from a vulnerable infusion component. An accumulator is further disclosed for use in combination with the safety device to compensate for time delays in full activation of the occlusion valve.
