The device also includes a base mounted on the film, the base comprising a first portion of a guide channel for receiving the catheter. A cover is coupled to the base via a hinge, the cover comprising a second portion of the guide channel, the cover further comprising a rounded portion extending from a distal end of the cover, wherein in the closed configuration, the catheter is completely enclosed by the rounded portion and the first and second portions of the guide channel. The device also includes a positional shift indicator fixedly attached to the catheter and configured to indicate positional shifts by the catheter within the guide channel. ## Claims ### Claim 1 A method of determining whether a catheter has moved relative to the catheter's entry point into a body, comprising: securing a base onto the body, wherein the base has a first side and an opposing second side, wherein the second side has an area for receiving the catheter; applying a cover to the base, wherein a portion of the cover is configured to receive the catheter and wherein, upon applying the cover to the base, a housing is formed that encloses at least a portion of the catheter; sealing the entry point using a first film; and determining whether the catheter has moved relative to the entry point by viewing a positional shift indicator comprising visible segments extending across the area receiving the catheter and configured to visually indicate a degree of a positional shift of the catheter relative to the area, wherein the positional shift indicator is physically coupled with the catheter after the catheter is received by the base and cover. ### Claim 2 (depends on 1) The method of claim 1, wherein securing the base onto the body is achieved by pressing the first side comprising an adhesive onto the body. ### Claim 3 (depends on 1) The method of claim 1, wherein sealing the entry point using the first film is achieved by pressing the first film comprising an adhesive proximate the entry point. ### Claim 4 (depends on 1) The method of claim 1, wherein the area comprises a first portion of a guide channel for receiving the catheter and wherein the cover comprises a second portion of the guide channel to receive the catheter. ### Claim 5 (depends on 4) The method of claim 4, wherein movement of the catheter is restricted by an adhesive disposed on the first and second portions of the guide channel. ### Claim 6 (depends on 4) The method of claim 4, wherein the cover further comprises a semi-circular member extending from a distal end of the cover and wherein, in the closed configuration, the catheter is enclosed by the semi-circular member and the first and second portions of the guide channel. ### Claim 7 (depends on 4) The method of claim 4, wherein the first portion of the guide channel in the base comprises a notch at a distal end of the first portion of the guide channel. ### Claim 8 (depends on 7) The method of claim 7, wherein the notch is disposed over a cutout portion of the first film. ### Claim 9 (depends on 7) The method of claim 7, further comprising inserting the catheter through the notch. ### Claim 10 (depends on 1) The method of claim 1, further comprising applying the cover to the base by pivoting the cover relative to the base using a hinge. ### Claim 11 (depends on 1) The method of claim 1, further comprising a first stabilizer extending outward from the base and over the body, wherein the first stabilizer facilitates a correct parallel alignment between the entry point and the body. ### Claim 12 (depends on 11) The method of claim 11, wherein the first stabilizer is located on a first tapered side of the base. ### Claim 13 (depends on 1) The method of claim 1, further comprising a second stabilizer extending outward from the base and over the body in a direction opposite the first stabilizer, wherein the second stabilizer facilitates a correct parallel alignment between the entry point and the body. ### Claim 14 (depends on 13) The method of claim 13, wherein the second stabilizer is located on a second tapered side of the base. ### Claim 15 (depends on 1) The method of claim 1, wherein the base or the cover comprises a recess. ### Claim 16 (depends on 1) The method of claim 1, further comprising inserting a biomedical sensor into the recess. ### Claim 17 (depends on 16) The method of claim 16, wherein the sensor is configured to detect signals related to at least one of an infection in the body, a movement of the catheter, or a functionality of the catheter. ### Claim 18 (depends on 1) The method of claim 1, wherein the base further comprises a tab member protruding from a side of the base. ### Claim 19 (depends on 1) The method of claim 1, further comprising pulling on said tab member to remove the base and the cover from the body. ### Claim 20 (depends on 1) The method of claim 1, wherein the visible segments extend perpendicularly across the area receiving the catheter.
