我科引进加拿大780~(60)Co治疗机,1975年开始应用于临床。10年来多用于垂直、旋转、钟摆治疗。因工作疏忽大意曾发生几次机头和治疗床碰撞造成床面损坏,治疗床头下降了15°左右,床面失去水平,影响治疗床的前后运动。致使病人要前后活动才能进行治疗,因维修困难又无外汇购买床面,~(60)Co治疗机面临停机危险。原780治疗床表面用铁皮,余三面是铝合金板,中间是塑料泡沫充填成实心整体。优点为床面重量轻、活动性能好、拆卸方便。缺点为铝合金韧性差、发生碰撞不能修理,易出现故障。作者等根据原机优点用松木为主料设计出一种新的木型治疗床,床面长210cm、宽46cm、厚10cm,与原床面外形相同。用两根三角铁固定在床的下面,角铁另一面加工
Our department introduced the Canadian 780~(60)Co therapy machine and began to apply it in clinical practice in 1975. More than 10 years for vertical, rotation, pendulum treatment. Due to work negligence, there were several collisions between the head and the treatment bed, resulting in bed surface damage. The treated bed had dropped by about 15° and the bed level was lost, affecting the front and back movements of the treatment bed. Due to the difficulty of maintenance and the lack of foreign exchange to purchase the bed, the (60) Co therapy machine is at risk of downtime. The original 780 treatment bed surface with iron, the remaining three sides is aluminum alloy plate, the middle is filled with plastic foam into a solid whole. The advantages are light weight on the bed surface, good activity performance and easy disassembly. The disadvantage is that the aluminum alloy has poor toughness, can’t be repaired by collision, and is prone to failure. The authors designed a new wood type treatment bed based on the advantages of the original machine, using pine wood as the main material. The bed length is 210cm, width 46cm, and thickness 10cm, which is the same as the original bed surface. With two triangles fixed under the bed, the other side of the angle iron processing
