Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of medical devices and more particularly to a catheter system. Background Art
[0002] Common types of catheter systems include an over-the-needle peripheral intravenous catheter ("PIVC"). As the name implies, an over-the-needle peripheral intravenous catheter can be mounted on an introducer needle having a sharp distal tip. The catheter system can include a catheter adapter, a peripheral intravenous catheter extending distally from the catheter adapter, and an introducer needle extending through the peripheral intravenous catheter. The peripheral intravenous catheter and the introducer needle can be assembled so that the distal tip of the introducer needle extends beyond the distal tip of the peripheral intravenous catheter, wherein, immediately before insertion into the skin, the bevel of the needle faces upward away from the patient's skin. The peripheral intravenous catheter and the introducer needle are typically inserted through the skin at a shallow angle into the patient's vasculature.
[0003] To verify the correct placement of the introducer needle and / or peripheral intravenous catheter in the blood vessel, the clinician can confirm the presence of flashback of blood in the flashback chamber of the catheter system or in the space between the introducer needle and the peripheral intravenous catheter. Once the placement of the introducer needle has been confirmed, the clinician can remove the introducer needle, thereby leaving the peripheral intravenous catheter in place for future blood draws or infusions.
[0004] In some cases, a catheter system (such as, for example, the BD NEOFLON available from Becton Dickinson, Inc. of Franklin Lakes, NJ) is used. TM Pro IV cannulae) may include a housing that can be mounted on the wings of the catheter system to aid in gripping the catheter system by the clinician. However, the housing is somewhat bulky, expensive to produce, and is not typically used after the catheter system is inserted into the patient's vascular system.
[0005] The subject matter claimed herein is not limited to embodiments that solve any disadvantages or that operate only in environments such as described above. Rather, this background is merely provided to illustrate one example technology area where some embodiments described herein may be practiced. Utility Model Content
