It is known in the art relating to medical dressings for the protection and securement of catheters to apply a dressing to a patient's skin to cover a catheter insertion site at which the catheter punctures a patient's skin. It is also common for medical clinicians (i.e., doctors, nurses, and other medical personnel) to alternatively or additionally apply strips of medical grade tape to attempt to secure the catheter or associated medical tubing. Another conventional clinical practice is to suture a catheter hub to a patient's skin to invasively and roughly secure the catheter to the patient. Further still, a variety of catheter and medical tubing securement devices are available for use in the medical field. These securement devices, however, are often bulky and cumbersome, hard to dress and/or remove with a dressing, may require a scissors or scalpel to physically cut them away risking catheter lumen or catheter pigtails damage in the process, may require two, three, or four pieces of tape to get reliable results, and may have costly and complex mechanical features; all of which can combine to both lower patient care clinical outcomes, and equally important, lead to higher healthcare costs due to added nursing costs.
It is also known in the medical field that poorly dressed and poorly secured catheters and associated tubing are likely to undesirably lead to irritation of both internal vascular wall damage at distal catheter tip due to in/out catheter tip motion at the insertion site, necessitating premature rotation and reinsertion of the catheter to a nearby new anatomical insertion site. Even worse, poorly secured catheters are susceptible to accidental dislodgement from the insertion site. For example, medical tubing connected to indwelling catheters, infusion needles and the like is often subjected to inadvertent but significant pulling forces either caused directly by patient movement or by snagging of the tubing on other objects. These pulling forces peel the medical tape or dressing securing the catheter and/or tubing off the patient's skin. This exposes the catheter, infusion needle, etc. to movement inward or outward, increasing the likelihood that the catheter, infusion needle, etc. will fail and have to be replaced and inserted into a new insertion site. Also, this may weaken the adhesion between the dressing and the patient's skin, potentially exposing the insertion site to harmful bacteria.
