PROBLEM TO BE SOLVED: To propose a system for reducing a discharge speed of an infusion while sustaining a high inject flow quantity required under a rapid infusion treatment.SOLUTION: A peripheral catheter (414) has diffusion means on a catheter tip (420) for reducing a discharge speed of an infusion within the catheter. A plurality of diffusion side holes (450) are provided on the tip portion of the catheter. Some examples further include a plurality of annularly arranged, staggered diffusion holes provided on the tip portion of an intravenous catheter to streamline the infusion discharged from the diffusion holes. An inner surface (464) of each diffusion hole is further angled relatively to the inner surface (482) of the catheter lumen (490) such that the infusion within the lumen is discharged form the catheter though the diffusion holes at an angle less than 90°. |
