A pressure injury classification refers to an auxiliary telescopic measuring device for comparing wounds of a crushed patient or a potential patient, thereby evaluating the classification to take corresponding medical care measures. The telescopic measuring device includes: a hollow body formed of the hollow body A side wall through slot； a display device partially contained in the hollow body and passing through the side wall slot and partially exposed to the hollow body, the display device is printed with at least one scale unit and at least one reference drawing unit A scrolling of the display device causes the display device to scroll and retract between a storage position substantially stored in the hollow body and a reference measurement position mainly exposed to the hollow body.一種壓傷分級參照輔助伸縮量測器，供比對壓傷患者或潛在患者的傷口，藉此評估分級以便採取對應的醫療照護措施，該伸縮量測器包括：一中空本體，該中空本體形成有一側壁穿槽；一個部分容置於上述中空本體且穿經上述側壁穿槽而部分暴露於上述中空本體外的顯示裝置，該顯示裝置印有至少一刻度尺規單元和至少一參照圖式單元；一捲動上述顯示裝置使該顯示裝置在一實質收納於上述中空本體的收納位置和一主要暴露於上述中空本體外的參照量測位置間捲動伸縮的捲動裝置。
