Problems solved by technology

However, prolonged use of a single support bandage can cause microbial growth on, in, or beneath the bandage, increasing the risk of infection to the subject or to persons close to the subject, such as family members or care provider
Additionally, microbial growth can be accompanied by an unpleasant odor and unsightly discoloration of the brace
Also, it is costly and time-consuming to discard and replace support bandages after one or a few uses, while conventional support bandages lose their compressive strength and elasticity after repeated washing and cycling

Embodiment 1

[0033] Example 1 Manufacture of Antimicrobial Elastic Support Bandage

[0034] Silver-coupled flexible fibers (“X-Static TM ") were obtained from Noble Biomaterials (Scranton, PA, USA). X-Static TM Fiber with 100% Spandex Yarn (Type 150D; Type: Spandex Yarn; Style: Bare Yarn; Evenness: High Evenness; Tenacity: High Tenacity, Type 150D; Twist: Untwisted; Pattern: Virgin; Yarn Count : highly elastic) are twisted together to form an antimicrobial warp. To form the non-antimicrobial warp, red and white polyester threads (100%; yarn count: 150D; pattern: twisted weave; yarn type: DTY; filament; textured; twist: 120TPM; evenness: equal ) twisted with 100% spandex yarn as described above. Antimicrobial and non-antimicrobial warp threads arranged in an alternating pattern: white polyester + spandex; red polyester + spandex; and 2wt%, 3wt%, 5wt% X-Static TM + Spandex, or 10wt% X-Static TM . Three white polyester + spandex threads are used to visually define the longitudinal edges...

[0036] Example 2 Antimicrobial Activity of Elastic Support Bandages

[0037] According to the standard ISO 20743:2013 (E) absorption of MRSA for four hours, the antimicrobial activity of the elastic support bandage described in Example 1 (2wt%, 3wt%, 5wt%, 10wt% of X-Static TM ) were evaluated (MSI Laboratories, Crystal Lake, IL). Briefly, the elastic support bandages were inoculated with bacteria and allowed to incubate for four (4) hours before bacterial colonies were counted.

Abstract

The invention discloses an antimicrobial elastic support bandage including a plurality of warps. Each warp extends along at least a part of the length and includes non-antimicrobial warp areas and antimicrobial warp areas which are arranged alternatively across the width. (a) Each non-antimicrobial warp area includes an elastic material which can be stretched in the length direction; (b) each antimicrobial warp area includes (i) a kind of flexible fibers coupled to a kind of antimicrobial metal and (ii) an elastic material which can be stretched in the length direction, and the flexible fibersare coupled to the elastic material; and (C) at least a part of the warps are spaced by about 3-20 micrometers. The antimicrobial elastic support bandage also includes a plurality of wefts. Each weftextends across at least a part of the width and includes a biocompatible material. At least some of the wefts are spaced by about 3-20 micrometers. At least a part of the warps are interweaved with at least a part of the wefts.

Description

technical field [0001] The present invention relates to antimicrobial bandages, including antimicrobial elastic support bandages, which provide coverage, support or compression to an injured part of the body of a subject or patient while having antimicrobial activity. Background technique [0002] Supportive bandages, such as compression wraps and short stretch wraps, are usually made from a woven combination of elastic and non-elastic textile materials. Elastic materials allow the support bandage to stretch partially or completely across the injured body part, and in some cases wrap around the injured body part to provide support and compression therein, while non-elastic materials are interwoven with elastic materials and Cover the injured body part. US Pat. Nos. 6,267,744, 4,207,885 and 5,647,842 describe stretchable bandages with various weaves to achieve desired stretch and support properties. [0003] In many cases, support bandages are used to relieve slow-healing i...
