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°.
Claims14
A peripheral catheter, comprising:
- a catheter body having a proximal end, a distal end, a lumen formed by an inner wall of the catheter body that extends between the proximal end and the distal end, and a distal lumen opening, the catheter body further having a truncated length sufficient to access a peripheral vein of a patient, wherein at the distal end, the lumen of the catheter body comprises a first section and a second section, wherein a diameter of the first section linearly decreases towards the distal end of the catheter body, wherein a diameter of the second section is constant, wherein the first section is proximal to the second section;
- a plurality of holes positioned on the distal end of the catheter body, each hole being formed through a wall thickness of the catheter body and in communication with the lumen, wherein first holes of the plurality of holes are arranged in a first annular ring and second holes of the plurality of holes are arranged in a second annular ring, wherein the first annular ring and the second annular ring are positioned within the first section of the lumen, wherein the first holes are staggered with respect to the second holes.
A catheter body configured for a peripheral catheter, the catheter body comprising:
- a truncated catheter body configured to access a peripheral vein of a patient;
- a lumen extending from a distal opening to a proximal opening, the lumen comprising an inner wall of the catheter body that extends between the distal opening and the proximal opening;
- and
- a plurality of holes positioned on a distal end of the catheter body, each of the holes being formed through a wall thickness of the catheter body and in communication with the lumen, wherein the plurality of holes comprises a first hole and a second hole, wherein an axis of the first hole is oriented to cross an axis of the second hole in a space exterior to the catheter body,
- wherein at the distal end of the catheter body, the lumen comprises a first section and a second section, wherein a diameter of the first section linearly decreases towards the distal end of the catheter body, wherein a diameter of the second section is constant, wherein the first section is proximal to the second section.
