To understand the industry challenges relating to wound care industry, Signicent’s experts went through thousands of scientific literature, journals, academic publications, and patent literature based upon which our team has discussed some of the most commonly faced challenges with innovative solutions.

The Tensile Strength of Natural Polymeric Yarns

The tensile strength of the conventional non-woven wound dressing is usually weak, reinforced by longitudinal stitches. Therefore, the vulnerability to the tensile force in the transverse direction is strongly felt. Therefore, it usually breaks up in the wounds making dressing removal more time and labor-consuming.

The aforementioned challenge can be resolved by using a multi-layered non-woven wound dressing. It is stitched up by natural polymeric yarns which enhances the resistance of wound dressing to the tensile force in both longitudinal and transversal directions.

Method of preparing multi-layered non-woven wound dressing

Preparing multiple natural polymeric layers:

  • Stacking the multiple natural polymeric layers to form a polymeric structure;
  • Preparing multiple natural polymeric threads, wherein each of the multiple natural polymeric threads is formed by twisting 300 to 3000 fibers; and
  • Stitching the polymeric structure with the multiple natural polymeric threads to form the multi-layered non-woven wound dressing, and continuous crossing lines penetrating through each layer of the multi-layered non-woven wound dressing
  • Non-woven multiple natural polymeric layers comprise alginate, chitosan, gelatin, hyaluronic acid, collagen.

The thread will not cause an immune rejection reaction due to its natural properties.

Advanced Wound Care

In this section of the wound care report, advancements happening in wound care have been discussed comprehensively.

ConvaMax™ combines high absorption and retention to protect from excess exudate. It is a UK-based technology with Multilayer dressings that are made from cotton, viscose, polyester, or foam absorb fluid within the material.

  • High fluid absorption- ConvaMax™ absorbs high levels of exudate into the Superabsorbent (SAP) core (up to 170g/100cm2) locking it away from the wound.
  • High retention of fluid and bacteria -ConvaMax™ retains the fluid within the SAP core, ensuring it is not released back to the wound.
  • Protease modulation-ConvaMax™ has been proven in-vitro to not only absorb MMP’s (matrix metalloproteinases) but also bind them.
  • Soft and conformable- It’s soft on the skin, easy to apply, and easy to remove for patient satisfaction. The protective blue backing prevents strike-through and maintains conformability.
  • A choice to suit each wound-Choice of the full range of sizes to fit any wound type. Choose from adhesive or non-adhesive versions.
  • Extra protection- Exudate can transfer through the Hydrofiber layer and be absorbed by ConvaMax™, providing a combination of an advanced wound contact layer and high absorption capacity.

Innovations in Wound Care

In this section of the wound care we report innovations that are talked about and can completely change this industry.

Portable Colour-changing paper-based band-aid

Research has developed bandages that change color and release antibiotics and/or reactive oxygen species in response to an infected wound which could curb the spread of antibiotic resistance.

  • The bandage is made up of paper coated with chitosan.
  • Bromothymol blue (BTB) responded to the acid environment at infectious sites, accompanied by a color change from green to yellow.
  • Ampicillin-loaded nanomaterials were coated with chitosan to lure negatively charged bacteria and achieved acid-responsive drug release, thereby killing DS bacteria.
  • For DR (drug-resistant) bacteria, nitrocefin was changed from yellow to red by the action of β-lactamase, which was secreted by many resistant bacteria.
  • PBA (green) for sensing bacterial infection (yellow) and drug resistance (red).
  • Developed a bandage that changes color from green to yellow in response to the acidic environment of a bacterial infection. The material of the dressing reacts to this environment by releasing an antibiotic to destroy drug-sensitive bacteria.
  • Low cost and easy operation and takes 4 h to sense.

CovaWound™ Silicone

CovaWound™ Silicone Self-Adherent Soft Silicone Foam Dressing with Border

  • CovaWound™ Silicone Self-Adherent Soft Silicone Foam Dressing with Border (Lite) is absorbent, atraumatic dressings consisting of a soft silicone adhesive that does not stick to the surface of a wound or cause epidermal stripping or pain upon removal.
  • Its absorbent core consists of polyurethane foam and non-woven fabric to lock in exudate and prevent the wound bed from drying out and the surrounding skin from becoming macerated. The outer surface of the product is a vapor-permeable membrane, which acts as a barrier to liquid and microorganisms.
  • The membranes present in the dressings:
  • Permeable Polyurethane Membrane: A vapor permeable polyurethane membrane that acts as a barrier to liquid and microorganisms.
  • Multi-Layer Exudate Management: Designed to absorb exudate and prevent maceration of peri-wound skin.
  • Gentle Silicone Adhesive: Facilitates application and retention of the dressing to intact skin. The layer does not stick to the surface of a wound or cause trauma to delicate new tissue upon removal.

Multilayer Foam Wound Dressing

3M™ Tegaderm™ Silicone Foam Dressings Feature Layers Of Innovation

  • The Patented spoke delivery system enables easy application, even with gloves on, so your other hand is free to position the patient.
  • 3M ™ Tegaderm ™ film backing combines 3M’s adhesive innovation and film expertise in a breathable dressing cover. The moisture control layer helps maintain an optimal moisture balance by facilitating evaporation through the film backing.
  • The superabsorbent layer further pulls moisture away and locks it in place to help minimize the backward migration(maceration).
  • Fenestrated foam layer improves flexibility and moisture absorption to help minimize the disruption of healing tissue.
  • Proprietary silicone adhesive keeps the dressing in place without damaging the wound area while allowing exudate to pass through.

Market Analysis And Segmentation

In this section of the wound care report the market analysis, trends and segmentation is summarized to better understand the dynamics of the global market.

  • The global wound care market is projected to reach USD 27.8 billion by 2026 from USD 19.3 billion in 2021, at a CAGR of 7.6% during the forecast period. The limitations of traditional wound dressings have propelled the growth of the advanced wound care market. The high cost of chronic wound treatments and advanced wound care products may negatively affect their adoption, especially in cost-sensitive markets.
  • An increase in population, with rising in the geriatric population has led to a surge in healthcare expenditure, and development in guidelines is expected to propel advanced wound care. Delayed healing is a key component of a comprehensive approach to wound care and presents the primary challenges to the treatment of chronic wounds.
  • The global wound care market is segmented into North America, Europe, the Asia Pacific, Latin America, and Middle East & Africa.
