Composition comprising collagen and honey
11400120 · 2022-08-02 · ·

A composition comprising collagen and honey can be produced by addition of an aqueous solution of honey to an aqueous suspension of collagen. The composition is for use in medicine and particularly for use in the treatment of a wound. A method for treatment of a wound comprises administering the composition topically to the skin of a patient.

Perforated Collagen Wound Interface For Use With Negative Pressure Wound Therapy
20220218530 · 2022-07-14 ·

The present disclosure relates generally to wound dressings that reduce the pressure drop observed during use in negative pressure wound therapy (NPWT). The wound dressings include a first layer and a second layer; wherein each of the first layer and the second layer independently comprise a biopolymer and a plurality of perforations, wherein each perforation comprises a width and an external perimeter, and wherein the first layer and the second layer are adjoined such that the external perimeter of each perforation in the first layer does not overlap or intersect with the external perimeter of each perforation in the second layer.

Method for preparing absorbable haemostatic composition for body and haemostatic composition prepared thereby

The present disclosure relates to a method for preparing an absorbable haemostatic composition for the body and the haemostatic composition prepared thereby, and the present disclosure is for providing a method for preparing an absorbable haemostatic composition for the body and the haemostatic composition prepared thereby, wherein the haemostatic composition can be used directly on the wound site when bleeding occurs in the surgical area such as surgical operation, trauma, etc. so that hemostasis can be effectively performed, the haemostatic composition can perform wound sealing, tissue repairing promotion, wound surface tissue protection, infection prevention, etc., the haemostatic composition is contained in haemostatic products such as gauze (cotton yarn), sponge, etc. to accelerate the hemostasis speed of the bleeding site and enable rapid hemostasis to be able to shorten the hemostasis time at the same time.

Wound dressing containing honey and collagen

A wound dressing makes use of a saccharide, such as Manuka honey, in combination with collagen in order to suppress the efficacy of matrix metalloproteinases enzymes (“MMPs”) present in chronic wounds. The mixture is applied to an absorbent surface that is designed to absorb the mixed saccharide only partially.
