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） Select the upper arm of the bind area should be one third of the humerus. 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. 接檢查井鋼模具 隔離墩模具 隔離墩鋼模具 流水槽模具 U型槽模具 螺桿啟閉機 卷揚式啟閉機 銅雕佛像通氣管，檢查接頭處是否銜接緊密、袖帶內氣囊是否漏氣。 Turn on the trachea to check if the connection is tight, and the air bag inside the cuff is leaking. 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. The upper extremities were 1.5 times the systolic pressure and the lower limb was twice the systolic pressure 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。 Set time: no more than 60 min, no more than 90 min. If the operation is long, the body should be able to return 10 to 15 minutes of blood flow and then block it. 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。 Pressure: before the tourniquet is pressurized, raise the limb by about 3 min, and accelerate the return of the static blood to reduce the amount of blood in the body. 8. 及時記錄充氣時間，術中注意加強對患者呼吸、循環功能的監測。 Keep track of the inflatable time in time, and be careful to monitor the patient's breathing and circulation. 9. 聽到提示音，做好放氣的準備（傷口須加壓包扎，防止滲血。放氣前，對有潛在性影響血壓的因素，如貧血或失血量過多者，需預防性應用小劑量麻黃素10～15 mg，以預防止血帶休克的發生，同時要適當加快補液速度以補充和維持有效的血容量）。 9. Hear a chime, ready to vent (wound must be pressurized bandage, prevent ooze blood. Deflated, with potential factors that influence the blood pressure, such as anemia or blood loss too much, the prophylactic use of small dose of ephedrine to 10 ~ 15 mg, in order to prevent the happening of the tourniquet shock, at the same time to speed up rehydration appropriate to supplement and maintain effective blood volume)
