    Abstract: A chitosan biomaterial is frozen in aqueous solution to form a frozen chitosan structure from which water is removed by a prescribed freeze-drying process to form a sponge-like chitosan structure having a thickness and a density. The sponge-like chitosan structure is compressed by application of heat and pressure to reduce the thickness and increase the density of the sponge-like chitosan structure to form a densified chitosan structure. The densified chitosan structure is further preconditioned by heating the densified chitosan structure according to prescribed conditions to form a wound dressing. The wound dressing possesses an adhesion strength and resistance to dissolution in high blood flow bleeding situations.

    Abstract translation: 将壳聚糖生物材料在水溶液中冷冻以形成冷冻的壳聚糖结构,通过规定的冷冻干燥方法从其中除去水,形成具有厚度和密度的海绵状壳聚糖结构。 通过施加热和压力来压缩海绵状壳聚糖结构,以减小海绵状壳聚糖结构的厚度和增加密度,形成致密化的壳聚糖结构。 通过根据规定的条件加热致密的壳聚糖结构,进一步预处理致密壳聚糖结构,形成伤口敷料。 伤口敷料在高血流量出血的情况下具有粘附强度和抗溶解性。

    Abstract: A hat headliner with temperature control members that is configured to provide a temperature dissimilar to that of its environment at locations along a lower edge of a hat. The present invention includes a body that is either permanently or releasably secured into the head cavity of a hat. The body of the present invention includes a perimeter band member wherein the perimeter band member has formed therein a plurality of receptacles. The plurality of receptacles have an interior volume wherein the interior volume is configured to receive and store temperature members. The temperature members include a housing from a malleable material having a temperature controlling gel therein. The receptacles have a first side and a second side wherein the first side of the receptacle is manufactured from a thermally conductive material and is adjacent a wearer's head.
