A catheter anchoring assembly includes a permeable adhesive strip, a platform for securing the catheter, and a flowable adhesive layer. The flowable adhesive layer adhesively secures the platform to the adhesive strip. The flowable adhesive is applied to one side of the strip with a skin-contacting adhesive on the opposite side of the strip. The flowable adhesive layer and strip are configured so that the flowable adhesive is spaced from the skin-contacting adhesive or, at the very least, is prevented from penetrating the skin-contacting adhesive. The flowable adhesive layer and strip also permit the assembly to be very flexible and, thus, comfortable for a patient to wear.

What is claimed is: 1. An intravenous catheter anchoring device for securing a catheter to a patient, said device comprising: a platform being configured to couple to the catheter; a flexible strip including a plurality of interstices therein and presenting first and second opposite surfaces, said strip having a thickness from the first surface to the second surface of about 0.005 to 0.015 inches and being permeable from the first surface to the second surface, said strip being configured to be removably attached to the patient along the first surface, said strip including a skin-contacting adhesive layer adhered to the first surface; a release liner removably attached to the first surface so that the first surface is at least partly covered by the release liner before the strip is attached to the patient; and an attachment layer located between and adhering the platform and strip along a wetted portion of the second surface, said attachment layer comprising an adhesive material that is flowable prior to being solidified, said attachment layer extending from the wetted portion into at least some of the interstices so that the adhesive material becomes solidified therein, said attachment layer being entirely spaced from the release liner when solidified so that the attachment layer is restricted from adhering the strip to the release liner. 2. The device as claimed in claim 1, said adhesive material comprising a hot-melt adhesive. 3. The device as claimed in claim 2, said hot-melt adhesive comprising thermoplastic polyamide. 4. The device as claimed in claim 2, said strip having a surface energy of at least about 18 Dynes/cm. 5. The device as claimed in claim 4, said strip having a surface energy of about 43 Dynes/cm. 6. The device as claimed in claim 5, said strip including a polyester substrate. 7. The device as claimed in claim 1, said adhesive material remaining flexible after being solidified so that the strip is operable to conform to the patient. 8. The device as claimed in claim 1, said strip including a non-woven tricot fabric substrate. 9. The device as claimed in claim 8, said substrate including filaments that form the interstices therebetween, said attachment layer mechanically interlocking with at least some of the filaments. 10. The device as claimed in claim 9, said adhesive material extending a depth greater than about half the thickness of the strip. 11. The device as claimed in claim 1, said attachment layer being spaced entirely from the skin-contacting adhesive layer. 12. The device as claimed in claim 1, said strip having a thickness from the first surface to the second surface of about 0.008 inches. 13. An intravenous catheter anchoring device for securing a catheter to a patient, said device comprising: a platform being configured to couple to the catheter; a flexible strip presenting first and second opposite surfaces, said strip having a thickness from the first surface to the second surface of about 0.005 to 0.015 inches and being liquid permeable from the first surface to the second surface, said strip being configured to be removably attached to the patient along the first surface, said platform and said strip being formed of different materials, said strip including a skin-contacting adhesive layer adhered to the first surface; a release liner removably attached to the first surface so that the first surface is at least partly covered by the release liner before the strip is attached to the patient; and an attachment layer located between and adhering the platform and strip along the second surface, said attachment layer comprising a hot-melt adhesive material. 14. The device as claimed in claim 13, said platform comprising a first plastic material, said strip comprising a second plastic material. 15. The device as claimed in claim 14, said first plastic material being selected from the group consisting of ABS, high density polyethylene, and polycarbonate, said second plastic material comprising polyester. 16. The device as claimed in claim 13, said hot-melt adhesive comprising thermoplastic polyamide. 17. The device as claimed in claim 13, said strip having a surface energy of at least about 18 Dynes/cm. 18. The device as claimed in claim 17, said strip having a surface energy of about 43 Dynes/cm. 19. The device as claimed in claim 18, said strip including a polyester substrate. 20. The device as claimed in claim 13, said adhesive material remaining flexible after being solidified so that the strip is operable to conform to the patient. 21. The device as claimed in claim 13, said strip including a non-woven tricot fabric substrate. 22. The device as claimed in claim 21, said substrate including filaments, said attachment layer mechanically interlocking with at least some of the filaments. 23. The device as claimed in claim 22, said adhesive material extending into the substrate a depth greater than about half the thickness of the strip. 24. The device as claimed in claim 13, said attachment layer being entirely spaced from the release liner when solidified so that the attachment layer is restricted from adhering the strip to the release liner. 25. The device as claimed in claim 24, said attachment layer being spaced entirely from the skin-contacting adhesive layer. 26. The device as claimed in claim 13, said attachment layer located between and adhering the platform and strip along a wetted portion of the second surface. 27. The device as claimed in claim 13, said strip having a thickness from the first surface to the second surface of about 0.008 inches.
