Wound Treatment Powder Protocol for Microbiome and Moisture Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wound treatment methods face challenges in maintaining wound site antiseptic sterility while preserving the functionality of the skin microbiome, and in managing moisture levels to facilitate healing without causing maceration or drying, particularly in open wounds such as burns, diabetic ulcers, and surgical excisions.
Innovation Solution
A two-part composition and application protocol using a mild antibiotic (ethacridine lactate) and zinc oxide, applied in a dry powder form, combined with emollients to maintain antiseptic conditions and promote healing by modulating immune responses and controlling moisture levels, while minimizing disruption to the skin microbiome.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If broad-spectrum antibiotics are applied to sterilize the wound site, then antiseptic sterility is improved, but the skin microbiome functionality deteriorates
Solution Approach 1:
The patent applies different treatment approaches to different zones: the wound bed receives antiseptic treatment while the perilesional microbiome zone receives microbiome-preserving care. This spatial differentiation allows sterilization of the wound site while preserving the beneficial microbiome in surrounding healthy skin.
Solution Approach 2:
The patent modifies the chemical parameters of antiseptic agents to reduce their broad-spectrum activity. By adjusting concentration, pH, or selecting narrower-spectrum agents, the treatment achieves sufficient sterilization of the wound bed while being less harmful to the microbiome in adjacent areas.
2Productivity
If the wound bed is kept moist to facilitate healing, then cellular proliferation and migration are improved, but maceration of bordering tissue occurs
Solution Approach 1:
The patent creates a moisture gradient across the wound site: the wound bed is maintained in a moist environment to promote cellular activities, while the perilesional tissue is kept at lower moisture levels to prevent maceration. This localized moisture management resolves the contradiction between healing promotion and tissue protection.
Solution Approach 2:
The patent employs dynamic moisture control that adapts to different wound zones and healing stages. Moisture levels are adjusted based on real-time assessment of wound bed conditions and perilesional tissue status, allowing optimization of healing while preventing maceration.
3Object-affected harmful factors
If the wound bed is allowed to dry to prevent maceration, then tissue integrity is improved, but cellular processes deteriorate
Solution Approach 1:
The patent applies different moisture conditions to different zones: the wound bed receives moisture to support cellular functions, while the perilesional tissue is protected from excess moisture. This spatial differentiation allows simultaneous prevention of maceration and maintenance of healing-promoting conditions.
Solution Approach 2:
The patent implements dynamic adjustment of moisture levels based on wound stage, tissue type, and environmental conditions. This allows the system to optimize the balance between preventing maceration and maintaining cellular activity throughout the healing process.

AI summary
Compositions and methods for wound treatment. Compositions may be formulated as a dry powder. Compositions may include an antibiotic and a metal-containing species. Each of the antibiotic and the metal-containing species may positively modulate wound bed and peri-lesional cellular processes supportive of healing. Methods may include a two-step protocol. The first protocol step may be spreading upon a wound surface an emollient-rich mixture of low-and high-molecular weight (MW) non-water-soluble ingredients of an anti-microbial ointment, forming an occlusive cover over the wound. The second protocol step may be to apply the compositions onto the cover. Low-MW emollients may migrate into, and solubilize components of, the dry powder. The solubilized components and the low-MW emollients may transport below the cover to the wound bed to facilitate effective wound healing. Initial testing and use studies have yielded good wound closures, with minimal-to-no scarring and high regain of function of repaired tissues.
