Description

Insert for a catheter system and catheter system
Technical Field
In general, the present invention relates to the field of medical devices. More particularly, the present invention relates to medical devices for various infusion therapies, such as intravenous catheters.
Background
Intravenous catheters are commonly used for a variety of infusion therapies. For example, intravenous catheters may be used to infuse fluids into a patient, such as physiological saline solutions, various medications, and total parenteral nutrition. Intravenous catheters may also be used to draw blood from a patient.
Common types of intravenous catheters are peripheral intravenous catheters ("PIVC"), peripherally inserted central catheters ("PICC") and mid-line catheters. The intravenous catheter may comprise an "over-the-needle" catheter that may be mounted over a needle having a sharp distal tip. The sharpened distal tip may be used to pierce the skin and vasculature of a patient. Insertion of the intravenous catheter into the vasculature may be performed after the needle pierces the vasculature. Needles and intravenous catheters are typically inserted through the skin at a shallow angle into the patient's vasculature with the bevel of the needle facing up and away from the patient's skin.
To verify proper placement of the introducer needle and/or intravenous catheter in the vasculature, the user typically confirms that there is flashback of blood, which may be visible to the user. In some cases, the introducer needle can include a notch disposed toward a distal end of the introducer needle, and responsive to the distal tip of the introducer needle being disposed within the vasculature, blood can flow proximally through the needle lumen, exit the needle lumen through the notch, and then travel proximally between an outer surface of the introducer needle and an inner surface of the intravenous catheter.
Thus, with the intravenous catheter at least partially transparent, the user may visualize a small amount of blood "flashback" and thus confirm placement of the intravenous catheter within the vasculature. The presence of a vasculature access indicator (such as flashback) may facilitate successful placement of the intravenous catheter. Once placement of the introducer needle within the vasculature has been confirmed, the user may temporarily occlude flow in the vasculature and withdraw the introducer needle, leaving the intravenous catheter in place for future blood and/or fluid draws.
During a blood draw, blood may pass through an adapter and/or needleless connector that is in fluid communication with the intravenous catheter via an extension tube. After collecting the blood sample, to prevent contamination by blood, the user typically rinses the adapter with saline and replaces the needleless connector. Flushing the adapter and replacing the needleless connector adds an additional operational step to the user and may increase the risk of blood exposure to the user. Furthermore, there is a risk of hemolysis when blood flows through the uneven, uneven path of the needleless connector.
The subject matter claimed herein is not limited to embodiments that solve any disadvantages or that operate only in the environments described above. Rather, this background is provided merely to illustrate one example area of technology in which some embodiments described herein may be practiced.
