The application discloses a detachable pressure tube and a blood pressure measurement device using the same. The blood pressure measurement device includes a cuff, a blood pressure case and a detachable pressure tube. When the cuff is broken and the detachable pressure tube and blood pressure case still keeps normal function, the cuff be separated from the blood pressure case and can be removed to a new cuff. The cost of maintaining the blood pressure measurement device is minimized.本創作提供一種可拆式壓力管體及其應用之血壓量測裝置。血壓量測裝置包括一壓脈袋、一血壓量測主機以及一可拆式壓力管體。當壓脈袋結構損壞,而可拆式壓力管體與血壓量測主機仍具有正常功能時,可將壓脈袋與血壓量測主機分離,並更換新壓脈袋至血壓量測主機,進而減少維護血壓量測裝置的成本。1‧‧‧血壓量測裝置10‧‧‧血壓量測主機11‧‧‧螢幕12‧‧‧電源按鍵13‧‧‧加壓按鍵15‧‧‧第一組接式連接埠16‧‧‧上表面20‧‧‧壓脈袋21‧‧‧壓力感測器22‧‧‧包覆件223‧‧‧容置件23‧‧‧流體袋24‧‧‧第二組接式連接埠30‧‧‧可拆式連接手段、可拆式壓力管體31‧‧‧管體本體311‧‧‧第一端312‧‧‧第二端32‧‧‧訊號線33‧‧‧第一連接部34‧‧‧第二連接部
