Despite advances in medical science, effective hemorrhage control in prehospital settings and self-management by injured individuals remain critical challenges. This study aimed to design and develop a hemostatic pack for hemorrhage control in both military and civilian environments, incorporating key attributes of an ideal product: rapid efficacy, ease of use, low weight, and cost-effectiveness.</span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:normal"><span style="unicode-bidi:embed"><span style="font-family:Calibri,sans-serif"><b><span style="font-size:10.0pt"><span style="font-family:&quot;Cambria&quot;,serif"><span style="color:#f79646">Materials & Methods:</span></span></span></b> <span style="font-size:10.0pt"><span style="font-family:&quot;Cambria&quot;,serif">T</span></span><span style="font-size:10.0pt"><span style="font-family:&quot;Cambria&quot;,serif">he study comprised three phases, including the production of chitosan-impregnated gauze from shrimp shell-derived chitosan, the design and fabrication of a self-aid tourniquet modeled on modern military designs, and final product packaging. The pack included hemostatic gauze, a tourniquet, and Surgifix (an elastic tubular net bandage), all contained in a lightweight, durable pouch.</span></span><span style="font-size:10.0pt"><span style="font-family:&quot;Cambria&quot;,serif"></span></span></span></span></span></span><br> <span style="font-size:12pt"><span style="font-family:&quot;Times New Roman&quot;,serif"><b><span style="font-size:10.0pt"><span style="font-family:&quot;Cambria&quot;,serif"><span style="color:#f79646">Findings:</span></span></span></b> <span style="font-size:10.0pt"><span style="font-family:&quot;Cambria&quot;,serif">The developed pack demonstrated feasibility for sterile production and assembly, with chitosan yields of 5-15g per 100g of shrimp shells.
