DETAILED DESCRIPTION

[0021] Referring now to the drawings in which like reference characters designate like or corresponding characters throughout the several views, there is shown in FIGS. 1-3, there is provided a medical securement device 100 for use in securing a tube-like structure, such as a catheter tube, chest tube, gastric tube, or abscess tube, to a patient 300 according to an embodiment of the present invention. The term “medical tube” 200 is used generally throughout this description to refer to all such tube-like structures that may be secured to a patient 300 using securement device 100.

[0022] The securement device 100 includes a flat base 102 having a top surface 104, a bottom surface 106 configured to contact a skin surface 302 of the patient, and a central circular opening 108 formed in the flat base. A cylindrical wall 110 having an outer surface 112, an inner surface 114 configured for placement adjacent the medical tube 200, a bottom end 116 surrounding the central circular opening 108, and a top end 118 located opposite the bottom end. Adhesive 120 is provided on the inner surface 114 of the cylindrical wall 110 and is configured to adhere to and to fix the medical tube 200 at a selected position within the cylindrical wall such that a selected length L of the medical tube extends below the bottom surface 106 of the flat base 102 and the skin surface 302. Also disclosed is a method for using the securement device 100 described above for the purpose of fixing or securing a medical tube 200 to a patient 300. More particularly, securement device 100 is useful for securing and stabilizing a medical tube 200 to a patient 300, where a length L of the medical tube extends through the skin surface 302 of the patient. This might include, for example, a catheter such as a suprapubic catheter, a chest tube, or other similar medical tubes. The securement device 100 may also be used in other situations for securing and stabilizing other tubes, including where the tube does not pass through an opening formed in a patient's skin.

[0023] When the securement device 100 is used, an end 202 of the medical tube 200 is usually first inserted through an opening or incision (not shown) in the skin surface 302 of the patient 300 so that a selected length L of the medical tube extends below the bottom surface 106 of the flat base 102 and the skin surface 302. Once the medical tube 200 has been correctly located, a portion of the medical tube 200 is placed into a space 122 formed within the cylindrical wall 110 such that the inner surface 114 of the cylindrical wall 110 is adjacent an outer surface 202 of the medical tube. The height H of the cylindrical wall 110, measured from bottom end 116 to top end 118, should be tall enough to allow for sufficient contact between the cylindrical wall and the medical tube 200 that a leak-proof seal can be formed. However, the cylindrical wall 110 should not be so tall that it interferes with clothing or movement of the patient.

[0024] In certain embodiments, the free end of the medical tube 200 (i.e. the end that has not been inserted through the skin surface 302) may be inserted through the central circular opening 108 of the securement device. In other embodiments, the securement device 100 includes a first slot opening 124 that formed in the flat base 102 and that extends from the central circular opening 108 to a periphery 126 of the flat base. Additionally, a second slot opening 128 extends from the bottom end 116 of the cylindrical wall 110 to the top end 118 of the cylindrical wall. The first slot opening 124 is joined together continuously with the second slot opening 128 to form a continuous slot that extends along the flat circular base and the cylindrical wall. This, in turn, provides separable sides 130 located adjacent either side of the continuous slot such that the cylindrical wall 110 can be widened or narrowed by moving the separable sides closer together or further apart. This continuous slot allow for the separable sides 130 to be opened and for the securement device 100 to be placed around and to fully or partially encircle the medical tube 200. In certain embodiments, the first slot opening 124 expands or flares and is wider at the periphery 126 than it is at the central circular opening 108. This expansion of the first slot opening 124 may assist in more quickly and accurately placing the securement device 100 around the medical tube 200. In particular, when in use, the slanted sides that form the flared slot opening 124 would tend to slide along the outer surface of the medical tube 200 and the automatically open the continuous slot to allow the medical tube to more quickly and easily be positioned within the cylindrical wall 200.

[0025] Advantageously, the separable sides 130 allow for the space 122 within the cylindrical wall 110 to be increased or decreased in order to accommodate medical tubes 200 having a range of outer diameters. Thus, the same sized securement device 100 may be used in conjunction with a range of medical tube sizes. Whether the medical tube 200 is partially or fully encircled by the cylindrical wall 110 depends on the circumference of the cylindrical wall and the outer diameter of the medical tube. Preferably, the cylindrical wall 110 surrounds at least a majority of the outer perimeter of the medical tube 200.

[0026] Next, the outer surface 202 of the medical tube 200 is placed into contact with the adhesive 120 that is located on the inner surface 114 of the cylindrical wall 110 in order adhere the securement device 100 to the medical tube such that the selected length L of the medical tube extends below the bottom surface 106 of the flat base 102. Importantly, no adhesive is provided on the bottom surface 106 of the flat base 102. As a result, there is no adhesion between the securement device 100 and the patient. Advantageously, this avoids the skin irritation issues that are common when securing medical tubes using conventional methods. In certain embodiments, adhesive is provided exclusively on the inner surface 114 of the cylindrical wall 110. In certain preferred embodiments, a removable adhesive cover 132 is placed over the adhesive, prevents inadvertent contact with the adhesive, and must be removed in order to make contact with the adhesive. In FIG. 1, a portion of the cover 132 is removed in order to illustrate the adhesive 120 that lies below the adhesive cover. The adhesive cover 132 may also be provided with a removal tab 134 that is formed integrally with the cover and is sized to be grasped by a user for assisting in the removal of the adhesive cover from the adhesive 120. In preferred embodiments, the removal tab 134 extends upwards away from the top end 118 of the cylindrical wall 110. Preferably, adhesive 120 can be easily removed with a solvent, such as isopropyl alcohol, such that the medical tube 200 can be selectively removed from the securement device.

[0027] Preferably, when the securement device 100 and medical tube 200 are attached to one another, the securement device is positioned such that the bottom surface 106 of the flat base 102 is in direct or indirect contact with the skin surface 302 of the patient 300 and surrounds the opening in the skin surface. For that reason, securement device 100, as a whole or at least flat base 102 are preferably formed using a medical grade or biocompatible material, such as a medical-grade silicone, which will is suitable for contact with the skin surface 302. Preferably, the flat base is formed from a stiff enough material and is sized with a diameter D that is sufficiently large to significant movement of the medical tube 200 at the incision site.

[0028] Preferably, the securement device 100 is then fixed in place such that the flat base 102 exerts a constant pressure force on the skin surface 302 directly at the incision site. Even more preferably, the constant pressure force is sufficient to arrest bleeding caused by the insertion of the medical tube 200 through the opening. Additionally, gauze (not shown) may be placed with the securement device 100 around the incision site in order to further reduce and absorb blood or other fluids.

[0029] There are several ways that the securement device 100 can be secured to the skin surface 302 in the selected location to provide the desired amount of constant pressure. For example, as shown in FIGS. 1 and 2, the securement device 100 may include a suture aperture 136 in the flat base 102 that is sized and configured to receive suture material 138 used in suturing the securement device to the patient. In preferred embodiments, a suture aperture 136 is located in the flat base 102 proximate each side of the continuous slot 124/128. A separate suture 138 may be passed through each aperture 136 or, as illustrated in FIG. 2, a single suture may be passed through both apertures. In still other embodiments, the securement device may include multiple apertures 136 in the flat base 102. In those cases, the apertures 136 preferably extend around the entirety of the cylindrical wall 110. Again, each suture aperture is sized and configured to receive suture material 138 for use in securing the securement device 100 to the patient 300. In other cases, suturing is not required when stabilization is provided through other means. For example, as shown in FIG. 3, certain medical tubes 200, including certain catheters, include inflatable balloons 204 located at one end. Usually, after the end of the tube 200 having the balloon 204 is inserted into a patient, the balloon may be inflated in order to keep the tube in place. This same procedure may be used with the securement device 100. In use, the end 202 of the tube 200 with the balloon 204 is inserted sufficiently far through the skin surface 302 that the balloon rests below the skin surface. The balloon 204 is inflated in order to fix and stabilize the medical tube 200.
