Problems solved by technology
[0005] However, conventional catheter adapter designs may have features that may increase the likelihood of complications, including but not limited to: (1) reduced "intravenous" length given the catheter lumen; Deviation from vein; (3) penetration and / or extravasation of drug / fluid into surrounding tissue; (4) phlebitis; (5) obstruction of catheter lumen (eg, tip of catheter lumen may become stuck in the vein wall and is blocked); (6) increased stress on the catheter lumen and vein; (7) larger "un-productive" of the catheter lumen joining the increased volume of fluid length; and (8) a larger catheter adapter footprint, which may affect catheter lumen loading when the dressing is used to secure the catheter adapter to the patient's skin

A catheter assembly includes a catheter adapter body and a catheter, the catheter adapter body including: a proximal end; a distal end; a lower surface; an upper surface; a catheter adapter channel formed within the catheter adapter body; the catheter includes: a proximal end; a distal end; a catheter lumen extending between the proximal end and the distal end of the catheter, the proximal end ofthe catheter coupled to the catheter adapter body such that the catheter lumen is in fluid communication with the catheter adapter channel; an angle formed between a lower surface of the catheter adapter body and a first longitudinal axis of the catheter adapter channel is greater than 4 degrees. The invention further relates to a catheter system and a catheter adapter. By the adoption of the technical scheme, S-shaped bending in a catheter in the prior art can be reduced or eliminated, and therefore the intravenous length of a given PIVC can be effectively increased and / or maximized. As a result, features in conventional catheter adapter designs that may increase the likelihood of complications are lessened or eliminated.
Description
technical field [0001] The present invention relates to medical devices, in particular, the application relates to a catheter assembly, a catheter system and a catheter adapter. Background technique [0002] Catheters are commonly used for various infusion therapies. For example, catheters may be used to infuse fluids such as saline solution, various medications, and total parenteral nutrition into a patient. Catheters can also be used to draw blood from a patient. [0003] A common type of catheter is a peripheral intravenous catheter on a needle ("PIVC"). As the name implies, the PIVC-on-needle can be mounted on an introducer needle with a sharp distal tip. The PIVC and introducer needle may be assembled such that the distal tip of the introducer needle extends beyond the distal tip of the PIVC with the bevel of the needle facing away from the patient's skin. The PIVC and introducer needle are typically inserted at a slight angle through the skin and into a patient's b...
