About ChitoGuard™ Military Hemostats

Our Military Hemostats are used in pre-hospital hemostatic scenarios such as regional conflicts, disaster emergency response, and medical assistance. ChitoGuard™ uses bioactive hemostatic materials that work on strong bioadhesion and electrostatic interaction between the positively charged chitosan and the negatively charged blood cells, which can stop the bleeding quickly.

(Image excerpt from the TCCC report)

According to TCCC reports, the Chitosan material products are the third-generation hemostats CoTCCC approved for battlefield use. Compared with chitosan, CM-Chitosan (Carboxymethyl chitosan)has a neutral pH, stronger stickiness to wound tissue, and faster liquid absorption. In addition, it relieves pain and is self-degradable. Therefore, as a hemostat, carboxymethyl chitosan material has obvious advantages over chitosan material. Our Carboxymethyl Chitosan(CM-Chitosan)material products are the third pro-generation hemostatic products.

Surgical Fabric

Compared with oxidized cellulose, bioprotein glue and collagen sponge, Surgical Fabric is superior to other hemostatic materials.

Surgical Fabric significantly promotes red blood cell aggregation after contact with blood in vitro. It increases red blood cell sedimentation without changing red blood cell morphology. It can make red blood cells to aggregate and trap red blood cells to form blood clots.

Chitosan-based Wound Dressing

Chronic wounds are wounds with specific causes that do not heal after 4 weeks of formal treatment.

Chitosan-based Wound Dressing are used to form a three-dimensional network structure. It can absorb a large amount of exudate at the wound site, forming a viscous gel, which adheres firmly to the wound. It can effectively isolate the undesirable environment and keep the moisture environment at the wound bed. It is conducive to wound healing.

The Chitosan-based Wound Dressing is suitable for the following wounds:
01. Surgical Incisions
02. Pressure Ulcers
03. Oral Ulcers
04. Painful Wounds
