Chitosan Hemostatic Gauze (Z-fold)

After contacting the blood and exudate of the wound, Chitosan Hemostatic Gauze (Z-fold) partially forms the sticky gel which adheres to and blocks the wound for rapid hemostasis. The ingredient of this gauze is chitosan derivative which is a polysaccharide with a similar molecular structure to the natural ECM and is prominent in biocompatibility. It has good properties of liquid absorbency and moisturization. This product is transformed to a soft gel upon absorbing liquid to provide wounds with a moisturizing and simulating ideal healing environment of ECM, and to improve the soothing sensation of the wound site, relieve pains, facilitate wound repair and healing, and improve the quality of wound recovery.

FAQs:

1.How is Chitosan Hemostatic Gauze (Z-fold) different from regular gauze?
The difference lies in the addition of chitosan and the Z-fold design. 
Chitosan is a natural polysaccharide extracted from marine organisms and crustaceans, characterized by biocompatibility, biodegradability, and biological activity. Its main mechanisms include the following:

• Promoting cell proliferation and differentiation: Chitosan can promote the proliferation and differentiation of skin cells, thereby accelerating wound healing. Chitosan can activate cell proliferation, such as epidermal growth and matrix metalloproteinase, and promote cell proliferation and extracellular matrix degradation.
• Anti inflammatory: Chitosan can inhibit inflammatory and reduce the interference of inflammation on wound healing. Chitosan can inhibit leukocyte chemotaxis and adhesion, reduce the release of inflammatory mediators, and thus reduce inflammatory.
• Promote angiogenesis: chitosan can promote angiogenesis, improve blood circulation, and accelerate wound healing. Chitosan can activate vascular endothelial cells and smooth muscle cells, promoting angiogenesis and repair.
• Antibacterial: Chitosan has a certain antibacterial effect, which can inhibit wound infection and reduce the interference of bacteria on wound healing.

The Z-fold design can better adapt to the curves and irregular lines around the wound, making it more comfortable and reducing pain and discomfort. Due to the better coverage of wounds with the Z-fold design, the amount of gauze used can be reduced, thereby saving resources and expanses.

2.Will Chitosan Hemostatic Gauze (Z-fold) swell when wet?
Yes. The swelling of the gauze can bring the following advantages:

• Good liquid absorption: The expanded gauze can absorb more liquid, especially for wounds with more bleeding.
• Strong adhesion: When the gauze expands, it can tightly fit the wound and is not easy to loosen, reducing gauze replacing frequency.
• Mild and Comfortable: It is as soft and comfortable as ordinary gauze, but due to the expansion of its volume, it can more effectively reduce the pressure on the wound.

3.Will Chitosan Hemostatic Gauze (Z-fold) stimulate the body?
No, it won’t. It is same as human physiological pH, no stimulation caused like normal Chitosan(+acidic additive) hemostats. It also does not generate heat and will not burn the casualty or caregiver.
