Abstract: In a tube coupling a resilient sealing boot is disposed between facing frusto-conical sealing surfaces to prevent fluid flow therebetween. A first tube is provided an external frusto-conical sealing surface and an outer cylindrical surface adjoining the external sealing surface, and a second tube is provided an internal frusto-conical sealing surface within an end thereof. The sealing boot is preferably formed entirely of a flexible graphite material to include a cylindrical collar that fits over the outer cylindrical surface of the first tube, and a skirt having one or more integral O-rings which engage one or both of the facing frusto-conical sealing surfaces as the ends of the first and second tubes are drawn together.

Abstract: A stabilizing fitting useful for securing a catheter hub or a syringe body adjacent to a venipuncture site is provided. The stabilizing fitting, of unitary pliable plastic construction, includes an elongated base having support members at each end. A VELCRO fastener is secured to an upper surface of each support member. A retaining strap removably attachable to the VELCRO fastener may be looped about the patient's arm, for example, to secure the stabilizing fitting in place without the use of skin-contacting adhesives. A catheter hub/syringe body retainer is centrally disposed between the support members and surrounded by a catheter hub/syringe body wing housing. A plurality of medical tube retaining slots are provided through each support member in alignment with the catheter hub/syringe body retainer. Alower surface of the base includes recesses for the retainer, the wing housing and the medical tube retaining slots.
