電動止血帶的使用方法和注意事項 1. 根據患者的年齡，體重，手術部位是上肢或下肢選用合適的袖帶（上肢：短、窄；下肢：長、寬）。 1. According to the patient's age, weight, choose appropriate surgical site is affected upper or lower limbs cuff (upper limb: short, narrow; lower extremity: length, width). 2. 袖帶不能直接接觸皮膚，而應用棉紙覆蓋在皮膚表面，然后綁袖帶。 2. The cuff is not direct contact with the skin, and application of cotton paper covering on the surface of the skin, then tie cuffs. 3. 選擇縛扎部位上肢應在肱骨上1/3段；下肢在大腿根部（因上肢避開了橈神經，下肢容易直接壓迫股動脈，但也有報道認為對于下肢遠端的手術，止血帶的袖帶越寬，四肢的周徑越小，阻斷血流所需的壓力就越低，使用者就越舒適，因此建議足趾手術時，止血帶最好放置在踝上方） 3. Select parts bound to plunge into upper limb should be on the humerus 1/3; Lower limbs in the thigh root (for upper limb to avoid the radial nerve, easy to direct pressure stocks lower limb artery, but there have also been reported for lower limb surgery, on the far side of a tourniquet cuff is wider, limbs weeks size is smaller, blocking blood flow to the required pressure, the lower the user is more comfortable, it is recommended that during the operation of digit tourniquet is best placed above the ankle) 4. 接通氣管，檢查接蓋土網 防寒布 麻繩 油麻繩 麻刀 瀝青麻繩 靜壓造型線 自動澆注機 鑄鐵拍門 鋼制拍門 玻璃鋼拍門頭處是否銜接緊密、袖帶內氣囊是否漏氣。 4. Connect the trachea, check whether joint closely linked, cuff if air leakage. 5. 設定壓力值：為了避免局部組織損傷及神經干擠壓傷，同時又要達到理想的止血目的，止血帶的設定壓力要根據局部組織薄厚、患者年齡、肢體周徑大小及局部動脈收縮壓而定。上肢為收縮壓的1.5倍，下肢為收縮壓的2倍 5. Set pressure value: in order to avoid local tissue injury and nerve crush injury, at the same time to achieve the ideal hemostatic purpose, tourniquet set pressure according to local tissue thick diameter week, patient age, body size and local artery systolic blood pressure. Upper limbs for systolic blood pressure of 1.5 times, 2 times of the systolic blood pressure of lower limbs 6. 設定時間：上肢一般不超過60 min，下肢不超過90 min。若手術時間長，則應讓肢體恢復血流10～15 min，然后再阻斷。 6. Set time: the upper limb is generally not more than 60 min, no more than 90 min of lower limbs. If the operation time is long, should let the body restore blood flow to 10 ~ 15 min, then block. 7. 加壓：止血帶加壓前，先將肢體抬高3 min左右，加速靜脈血回流，以減少肢體血量。
