The present invention provides a thermosensitive hydrogel composition, which includes chitosan, β-glycerophosphate, and glycerol. The thermosensitive hydrogel composition is changed between a transparent sol state and an opaque/turbid gel state in accordance with the temperature variation, thus it can be applied to the field of temperature warning. In addition, because the components of the thermosensitive hydrogel composition is biodegradable, biocompatible, and non-toxic, the thermosensitive hydrogel composition is environment-friendly and safely. The present invention also provides a dressing containing the thermosensitive hydrogel composition.本發明提供一種溫感水凝膠組成物,包括有幾丁聚醣、β-甘油磷酸鹽以及丙三醇。本發明的溫感水凝膠組成物可依據溫度的變化而於透明溶膠態與不透明/混濁凝膠態之間轉變,因此能夠應用於溫度警示的領域。此外,本發明的溫感水凝膠組成物的組分具有生物可降解性、生物相容性以及無毒性,因此還具有環保以及安全性佳的優勢。本發明還提供一種包含有該溫感水凝膠組成物的敷料。
