Provided herein are devices and systems for use in vascular access, and, in particular, dressings and vascular access systems including such dressings.
Properly dressing a catheter is important for a catheter’s dwell time, minimizing the risk for patient discomfort, dislodgment, and phlebitis among other conditions. Dressings can be designed for integrated catheters with a 45-degree side port. The angled slit in these dressings allows for them to be applied around the extension set, while maintaining a seal that helps prevent microbial ingress. However, the slit often sticks to the extension set during application, resulting in added manipulation of the catheter before the dressing is properly secured. This increases the risk for dislodgment and skin irritation. In addition, existing dressings intend alignment of a nonwoven border with the wings of the adapter and alignment of the slit with the extension set. This alignment is not intuitive for many users, often resulting in improper use.
Further, for many typical dressings, visibility is limited to the area around the insertion site. Having visibility around the extension set and nose of the adapter is important to monitor the health of a patient’s catheter insertion site. Visibility along the path of the line draw device allows for tracking and troubleshooting if any problems arise. Accordingly, there is a need in the field for dressings that allow for improved visualization and securement of an integrated catheter with an extension set.
Provided herein is a dressing for use with a catheter assembly, including a base defining a perimeter and an interior, the base comprising a bottom surface configured to contact skin of a patient and comprising a first opening in the perimeter, and a cover portion attached to the base and configured to cover a site of a catheter insertion, the cover portion comprising a second opening, the second opening configured to align with the first opening in the base when the dressing is applied to a patient’s skin.

In non-limiting embodiments of any of the aforementioned dressings, alignment marker(s) 160 may be arranged on base 110 and/or cover portion 120 of dressing 100. In non-limiting embodiments, such alignment markers function to provide an indication to a medical professional of any displacement of dressing 100 and/or catheter adapter 12, relative to the site of insertion of catheter 22. This can aid a medical professional in determining whether dressing 100 and/or catheter adapter 12 has moved an unacceptable difference (e.g., raising issues of sufficiently preventing opportunity for infection or of decreased use (e.g., kinking, dislodgment) of catheter 22 that can limit the ability to introduce medical devices (e.g., devices for use in line draw applications) and/or medicaments into the patient through catheter 22 and/or limit the ability to withdraw blood through catheter 22), such that dressing 100 and/or catheter should be removed and/or reapplied.
