The present invention relates to a spray patch composition for the indirect real-time determination of bacterial infections on superficial wounds by means of colorimetric pH detection. In particular, said composition is a sprayable composition comprising a plant extract comprising anthocyanins, at least one film-forming polymer capable of forming a polymeric film, at least one plasticizer, at least one surfactant; and at least one solvent. The present invention also concerns a process for the production of said spray patch composition and a kit containing it.

This invention belongs to the field of biomedical materials technology, specifically relating to a highly biocompatible carrageenan-tangerine peel composite hydrogel, its preparation method, and its application. The carrageenan-tangerine peel composite hydrogel contains 5-25 mg / mL carrageenan and 5-25 mg / mL tangerine peel. The prepared carrageenan-tangerine peel composite hydrogel does not require the addition of an external crosslinking agent, possesses good gel-forming ability, suitable mechanical strength, excellent biocompatibility, and good injectability. It fully retains the anti-inflammatory and antioxidant properties of active ingredients such as flavonoids and polysaccharides in tangerine peel, and synergizes with the cell-friendly matrix effect of carrageenan, significantly enhancing its application effect in skin tissue repair and functional recovery. It is suitable for various medical scenarios such as skin anti-aging, superficial wound repair, and tissue regeneration.

The present disclosure provides a wound brush (40) for removing superficial wound tissue form the epidermis and dermis of a patient The wound brush (40) comprises a wound brush base (1, 11) comprising a handle (2, 12) for holding the wound brush (40) and a shaft (3), a brush head connector (6, 19) comprising a base (7,23) and a shaft (8, 24) extending from a first side of the base (7, 23) and removably connected to the shaft (3) of the wound brush base (1, 11), and at least one brush head (30) removably connectable to the brush head connector (6, 19). The brush head (30) comprises a base (31) removably connected to the brush head connector (6, 19) and a pattern of bendable bristles (32) extending from a first side of the base (31), there being a gap in between neighbouring bristles (32). The base (31) and the bristles (32) that form the brush head (30) are made of a same material and the pattern of bendable bristles (32) is integrally formed with the base (31).

The invention relates to a composition for skin repair and a preparation method and application thereof, the composition comprises gallic acid or a derivative thereof and trehalose, and can be used for skin superficial repair; the composition further comprises Ectoine or a salt thereof and sodium hyaluronate, so that the promoting effect of the composition on skin wounds can be further improved, uncomfortable symptoms are effectively relieved, the skin absorptivity is improved, and the sensitization risk is reduced; the composition can be prepared into a preparation which is used for recovery of superficial wounds, surgical suture wounds, small wounds, scratches and incision wounds or used as a product after micro-plastic surgery, and has important clinical value and practical significance.

A liquid bandage capable of photocatalytic production of hydrogen peroxide and a preparation method therefor. Components of the liquid bandage comprise 0.1-5 wt% of a zinc-based semiconductor photocatalyst modified with a phenol organic compound, 2-10 wt% of a film-forming material, 0.1-3 wt% of a humectant and 82-97.8 wt% of a mixed volatile solvent. The liquid bandage is not restricted by the shapes and sizes of wounds, and is suitable for various superficial wounds on the human body surface. In addition, under light conditions, the liquid bandage can continuously and stably produce hydrogen peroxide, and according to the severity of wounds, different amounts of the liquid bandage can be applied so as to automatically regulate the yield of hydrogen peroxide. The liquid bandage has long-term use stability, thereby achieving long-term and efficient antibacterial and bactericidal effects.

The invention discloses a medical glucan skin repair dressing, which comprises Ectoine, beta-glucan, sodium hyaluronate, trehalose, sodium carboxymethyl cellulose and the like, and is a sterile liquid dressing without glycerol and traditional chemical preservatives. The dressing has appropriate viscosity, excellent film-forming property and flexibility, can quickly form a transparent, breathable and flexible protective film after being applied to a wound surface, can be used for nursing skin barrier injury, low sensitization and healing promotion of superficial wound surfaces, energy equipment postoperative wound surfaces and the like, and is convenient to use.
