Embodiment 1

[0020] The content of calcium alginate fiber is 92.0%, and the content of chitosan fiber is 8.0%. First, the calcium alginate fiber and chitosan fiber are opened and mixed evenly, combed into a fiber web by a carding machine, and then acupuncture The process is processed into non-woven sheets, which are finally cut by a cutting machine into a size (7.5×7.5cm) that matches the width of the self-adhesive elastic bandage.

Embodiment 2

[0022] The content of calcium alginate fibers is 81.5%, and the content of chitosan fibers is 18.5%. First, the calcium alginate fibers and chitosan fibers are opened and mixed evenly, and then they are combed by a carding machine to form a fiber web and then flattened by acupuncture. The process is processed into non-woven sheets, which are finally cut by a cutting machine into a size (10×10cm) that matches the width of the self-adhesive elastic bandage.

Embodiment 3

[0024] The content of calcium alginate fiber is 68.5%, and the content of chitosan fiber is 31.5%. First, the calcium alginate fiber and chitosan fiber are opened and mixed evenly, and then carded by a carding machine to form a fiber web, and then needle punched The process is processed into a non-woven sheet, which is finally cut into a size (8×8cm) that matches the width of the self-adhesive elastic bandage by a cutting machine.

[0025] The functional biological dressing sheets prepared in the above examples 1 to 3 were found to be antibacterial when the content of calcium alginate fibers was 81.5% and the content of chitosan fibers was 18.5%. The most significant effect is that it does not stick to the wound and better promotes wound healing.

[0026] Alginic acid is a natural macromolecular compound widely present in brown seaweed. It is a high molecular carboxylic acid that can combine with metal ions to form various alginates. Alginic acid itself is a water-insoluble ...

Abstract

The invention relates to a composite self-adhering elastic bandage of a functional biological dressing, which comprises a self-adhering elastic bandage and a functional biological dressing sheet. The functional biological dressing sheet is adhered to one end of the self-adhering elastic bandage by an adhesive or is sewn to be fixed at one end of the self-adhering elastic bandage; the functional biological dressing sheet is prepared by 68.5 percent to 92.0 percent of calcium alginate fibers and 8 percent to 31.5 percent of chitosan fibers, which are used as the raw materials; and the calcium alginate fibers and the chitosan fibers are processed by acupuncture to form a non-woven fabric sheet. The advantages of the self-adhering elastic bandage and the functional biological dressing sheet are combined; the effect of rapidly winding and binding a wound surface or a wound is achieved; the composite self-adhering elastic bandage for the functional biological dressing is convenient to rapidly treat the wound and the wound surface, can also be used for stopping bleeding and promoting wound healing and is suitable for emergency treatment such as first aid, field damage, movement damage and the like.

Description

technical field [0001] The invention relates to a functional biological dressing composite self-adhesive elastic bandage directly used for wounds. Background technique [0002] Self-adhesive elastic bandage is an elastic bandage with good self-adhesive and breathable properties, and has been widely used in sports protection, medical dressing and industrial operation protection. Patent No. 00117267.0 Chinese patent discloses a self-adhesive elastic bandage with double-sided spraying of natural latex. This elastic bandage has the advantages of easy to use, good air permeability, and smooth dressing. [0003] However, self-adhesive elastic bandages cannot directly contact wounds and wound surfaces. When using self-adhesive elastic bandages to treat wounds and wound surfaces, dressing sheets need to be used first, which is inconvenient to operate. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies in the prior art and prov...
