DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
(7) Referring now to the drawings,
(8) While a horseshoe shape is depicted, frame 15 can be of any shape such as circular, rectangular or other polygonal shapes. Curved shapes are more preferred, however, because they are more resistant to dislodging the adhesive seal than hard edges and corners.
(9) The bottom surface 21 of frame 15, base strip 15A, and strips 16 are coated with an adhesive that facilitates the securement of the IV holder 10 to the skin of a patient. The frame 15 is preferably made of a soft pliable material with an adhesive back such as the 1/16 inch polyethylene foam tape 1772 manufactured by 3M®. Additional strips 16 may be fabricated from similar materials. It should also be understood that the frame 15 can be made of a more rigid material such as a hard plastic to resist removal and increase durability.
(10) The adhesive underside of frame 15, base strip 15A, and strips 16 are releasably secured to backing 45 until they are needed. A frangible portion, such as a perforation 47, permit base strip 15A and its adhesive backing to be detached from frame 15. Likewise, lines of weakening or perforation 48 permit separation of strips 16 from frame 15 and base strip 15A or from each other for separate application or to reservation for later use. Backing 45 can contain frangible portions to permit removal of the backing 45 from frame 15 by the operator with one hand.
(11) The additional strips 16 provided can be used for a number of purposes. While the IV holder is initially secured by frame 15 and base strip 15A, base strip 15A is removable for servicing the Luer fitting. When servicing is complete, the Luer fitting can be resecured by using the strip 16 in place of the removed base strip 15A. Strips 16 are also used to secure the IV tubing upstream of the insertion site as shown in
(12) A window 40 covers the first portion 30 of the aperture 20. The peripheral edge of the window 40 is permanently secured to frame 15. Window 40 preferably is made of a urethane or similar material and is flexible, clear, breathable and sterilizable to minimize contamination when the IV holder is applied. The underside of window 40 optionally includes an adhesive coating to secure an IV needle (not shown) to the skin and minimize gaps between the window 40 and the skin to further minimize contamination. With these qualities, window 40 is positioned over and provides a viewable window to the insertion site so that any contamination can be monitored while simultaneously providing a barrier around the insertion site.
(13) While not strictly necessary, there is a benefit to be obtained if the IV holder 10 is longer (i.e., in the Y direction) than it is wide (i.e., in the X direction). A narrower width provides for better support and securement of the holder 10. Additionally, a longer length allows for added versatility in the positioning of the holder relative to the Luer fitting.
(14)
(15) The holder 10 is further preferably positioned so that cylindrical Luer fitting 70 is positioned in the second portion 35 of the aperture 20. This permits the Luer fitting to extend upwardly through the second portion 35 of the aperture 20 and does not interfere with window 40. Base strip 15A is used to secure the IV tubing 80 to the patient's skin upstream of the Luer fitting 70. Further adhesive strips 16 are be used to secure the IV tubing 80 at other positions to minimize the risk of dislodging the IV assembly.
(16) Secured in this manner, the window 40 of IV holder 10 provides a barrier against infection and contamination of and a way to visually inspect the insertion site 65. Because the window 40 secures the IV needle 60, which has a small diameter in comparison to Luer fitting 70, the flexible window 40 substantially contours around the diameter of the needle 60 and establishes a seal by minimizing gaps between the window 40 and the patient's skin 67. Luer fitting 70 is secured in part by base strip 15A upstream and the holder 10 and window 40 downstream. By positioning the Luer fitting 70 in the second portion 35 of aperture 20, the excessive height and diameter of fitting 70 (in comparison to needle 60 and tubing 80) does not interfere with the securement of the IV holder 10.
(17) In the event that it is necessary to detach the Luer fitting 70 for service or to clear needle 60, base strip 15A is readily removed by tearing along lines of weakening 47. Luer fitting 70 is then unthreaded from needle 60, serviced, and replaced without the need to remove or otherwise disturb frame 15 and window 40 of the IV holder 10. Once the service is complete, the Luer fitting 70 and the IV tubing 80 is secured by one of the reserved adhesive strips 16.
(18)
(19) Spacer frame 102 defines an aperture 110 which can be divided into a first portion 120 and a second portion 125. A transparent flexible window 140 is secured to the spacer frame 102 over first portion 120 of aperture 110. Spacer frame 102 further includes apertures 131 formed therethrough frame 102 corresponding to pins 130 on the base frame 101.
(20) Cover plate 103 defines the first portion 120 of aperture 110 and further includes apertures 132 formed therethrough corresponding to pins 130 on the base frame 100. The cover plate 103 also includes a transparent semi-cylindrical housing 150 dimensioned and shaped to seat over a cylindrical Luer fitting positioned in the second portion 125 of aperture 110. Housing 150 is preferably rigid for added protection and securement of the Luer fitting underneath. A rigid housing also minimizes the risk of dislodging or displacing the IV holder or IV needle by the patient's actions. The housing 150 may also include other covers or members shaped to cover portions of an IV needle or fittings.
(21) In use, the base frame 101 is adhesively secured to the patient's skin after the insertion of the IV needle. Spacer frame 102 and cover plate 103 are then mounted on base frame 101 by matching pins 130 with apertures 131 and 132. Ideally, the base frame 101 is positioned so that the IV needle is in the first portion 120 of aperture 110 and the Luer fitting is in second portion 125 of aperture 110 aperture 125 and under the housing 150 of cover plate 103.
(22) While base frame 101, spacer frame 102 and cover plate 103 are shown to be generally coextensive with each other in
(23) Housing 150 is be preferably designed to be universally applied to and used with most if not all Luer fittings in the marketplace. Alternatively, housing 150 can be designed so that its interior has a raised surface complementing a similar surface on a matching Luer fitting 170.
(24)
(25) In lieu of grooves, the complementary surfaces of the interior of housing 250 and the outer surface of Luer fitting 270 can be designed using ridges, tabs, or other uneven surfaces. In addition to providing an additional level of securement between the Luer fitting and the IV holder, such a design promotes the use of matching sizes of IV holders and Luer fittings.
