在骨科病人牵引治疗中 ,颅骨牵引、颌枕带牵引和下肢皮牵引均需要床头牵引架的滑轮进行反牵引力的平衡牵引。床头牵引架的两端无固定装置 ,在做其他操作时易被人碰撞、滑动致牵引错位、颅骨牵引器脱出 ,严重影响牵引的治疗效果。为了保证持续有效的牵引效果 ,有利于其他护理技? In the traction treatment of orthopaedic patients, the traction of the skull, the traction of the maxillary occipital zone and the traction of the lower limbs all require the pulleys of the bed traction frame to carry out the balanced traction of the anti-traction force. There are no fixed devices at the two ends of the bed traction frame, and it is easy to be bumped by people when doing other operations, resulting in traction dislocation and sliding of the skull traction device, seriously affecting the therapeutic effect of traction. In order to ensure continuous effective traction, it is beneficial to other nursing techniques.
