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 military and civilian environments, incorporating key attributes of an ideal product: rapid efficacy, ease of use, low weight, and cost-effectiveness.</span></span></span><br> <span style="font-size:11pt"><span style="unicode-bidi:embed"><span style="line-height:107%"><span calibri="" style="font-family:"><b><span style="font-size:12.0pt"><span style="line-height:107%"><span cambria="" style="font-family:">Methods</span></span></span></b><span style="font-size:12.0pt"><span style="line-height:107%"><span cambria="" style="font-family:">: </span></span></span><span style="font-size:12.0pt"><span style="line-height:107%"><span cambria="" style="font-family:">The study comprised three phases: (1) production of chitosan-impregnated gauze from shrimp shell-derived chitosan; (2) design and fabrication of a self-aid tourniquet modeled on modern military designs; and (3) final product packaging.
