start;background-color: rgb(255, 255, 255);"><span style="overflow-wrap: break-word;font-weight: 700;">1. 日常检查和维护</span></p><p style="white-space: normal;overflow-wrap: break-word;color: rgb(68, 68, 68);font-family: Tahoma, &quot;Microsoft Yahei&quot;, Simsun;font-size: 14px;text-align: start;background-color: rgb(255, 255, 255);">1.1. 环境&nbsp;<br style="overflow-wrap: break-word;"  />1) 温度保持&nbsp;<br style="overflow-wrap: break-word;"  />在扫描状态下,温度保持在20°～28°(变化范围不超过5°/小时)。&nbsp;<br style="overflow-wrap: break-word;"  />在外界温度小于0°或者大于35°的情况下,建议晚间不要关闭空调,每天开机准备扫描病人之前,应首先使室温保持在20°～28°半小时以上。&nbsp;<br style="overflow-wrap: break-word;"  />2) 湿度保持&nbsp;<br style="overflow-wrap: break-word;"  />在扫描状态下,相对湿度保持30%～70%(无凝露)。&nbsp;<br style="overflow-wrap: break-word;"  />在外界湿度较大的情况下,建议即便不使用设备,也应将除湿机打开.开机前如果湿度过大,建议先开除湿机,使湿度在允许的范围内半小时以上再开机扫描。&nbsp;<br style="overflow-wrap: break-word;"  />如果相对湿度低于30%,建议使用室内蓄水池蓄水,湿度达到要求后,再开机扫描。&nbsp;<br style="overflow-wrap: break-word;"  />如果湿度不能保证要求,将导致图像伪影或质量下降,甚至损坏设备。&nbsp;<br style="overflow-wrap: break-word;"  /><br style="overflow-wrap: break-word;"  />1.2&nbsp; 清洁和消毒&nbsp;<br style="overflow-wrap: break-word;"  />1) 地面清洁&nbsp;<br style="overflow-wrap: break-word;"  />地面清洁应使用真空吸尘器,清洁时不要扬起灰尘。&nbsp;<br style="overflow-wrap: break-word;"  />在需要使用水或液体清洁剂时,不要使水溅入机器内部。&nbsp;<br style="overflow-wrap: break-word;"  />机架下面的地面应定期清理,并注意有无泄漏物。&nbsp;<br style="overflow-wrap: break-word;"  />2) 外罩清洁&nbsp;<br style="overflow-wrap: break-word;"  />外罩清洁可使用中性清洁剂,用布擦去污迹.不可用强酸性或强碱性的清洁剂清洗外罩。&nbsp;<br style="overflow-wrap: break-word;"  />3) 床垫消毒&nbsp;<br style="overflow-wrap: break-word;"  />与患者接触的应用部分应每次使用后用90%的洒精或消毒剂擦洗消毒,每次应最少擦洗三遍.擦洗时擦洗液不得溅入设备内部。&nbsp;<br style="overflow-wrap: break-word;"  /><br style="overflow-wrap: break-word;"  />1.3&nbsp; 操作台</p><p style="white-space: normal;overflow-wrap: break-word;color: rgb(68, 68, 68);font-family: Tahoma, &quot;Microsoft Yahei&quot;, Simsun;font-size: 14px;text-align: start;background-color: rgb(255, 255, 255);">1) 显示器&nbsp;<br style="overflow-wrap: break-word;"  />如果屏幕有污迹,请用干净的软布擦拭屏幕.如果用玻璃清洁液,请不要用含有抗静电溶液或类似添加物的任何类型的清洁剂,因为可能操作损伤屏幕的涂覆层。&nbsp;<br style="overflow-wrap: break-word;"  />不可用圆珠或螺丝刀等尖锐的物体去摩擦、触摸或敲打屏幕表面,因为可能会刮伤显像管。&nbsp;<br style="overflow-wrap: break-word;"  />请用软布蘸温和的洗涤剂溶液擦拭清洁机壳,前面板和控制器.不可使用任何类型的砂纸、研磨粉和酒精、苯等溶剂。&nbsp;<br style="overflow-wrap: break-word;"  />2） 键盘和鼠标&nbsp;<br style="overflow-wrap: break-word;"  />键盘可用软布清洁，不要将水或其他液体溅入键盘内。&nbsp;<br style="overflow-wrap: break-word;"  />鼠标可定期（每周）打开轨迹球，清理内部的脏物。&nbsp;<br style="overflow-wrap: break-word;"  /><br style="overflow-wrap: break-word;"  />1.4&nbsp; 电缆&nbsp;<br style="overflow-wrap: break-word;"  />铺设在室内的电缆应定期检查,如果是电缆沟,应注意鼠害。.<br style="overflow-wrap: break-word;"  /><br style="overflow-wrap: break-word;"  />1.5&nbsp; 特别处理&nbsp;<br style="overflow-wrap: break-word;"  />在给病人做身体检查时常常会遇到很多特殊的情况,如病人在扫描过程中出现呕吐,流血,或小孩撒尿等,遇到这种情况应立即处理,防止进入机器内部,如果已经进入,应及时关闭机架电源,打开机架的前罩,进行内部清理,防止机器短路。&nbsp;<br style="overflow-wrap: break-word;"  /><br style="overflow-wrap: break-word;"  /><span style="overflow-wrap: break-word;font-weight: 700;">2&nbsp; 定期维护和保养&nbsp;<br style="overflow-wrap: break-word;"  /><br style="overflow-wrap: break-word;"  /></span>2.1&nbsp; 主旋转轴承的保养&nbsp;<br style="overflow-wrap: break-word;"  />CT机使用每六个月应加润滑脂一次,每次加润滑脂量根据使用的频度不同而不同。&nbsp;<br style="overflow-wrap: break-word;"  />平均日患者大于20人次的设备则每次加润滑脂应不超过200克,平均日患者量小于10人次的设备则每次加润滑脂量应不超过100克。&nbsp;<br style="overflow-wrap: break-word;"  />注意:&nbsp; 严禁使用添加二硫化钼的润滑脂。&nbsp;<br style="overflow-wrap: break-word;"  /><br style="overflow-wrap: break-word;"  />2.2&nbsp; 螺丝紧固 根据需要打开机罩,在保证断电的情况下检查端子排上的螺丝是否松动,接插件是否牢靠,线扣及线托是否脱落,如发现则加固之。&nbsp;<br style="overflow-wrap: break-word;"  /><br style="overflow-wrap: break-word;"  />2.3&nbsp; 主旋转同步带的张紧调整&nbsp;<br style="overflow-wrap: break-word;"  />每三个月应检查机架旋转同步带的松紧度,方法如下:&nbsp;<br style="overflow-wrap: break-word;"  />用约5KG的力度压同步皮带,其弧度应在14±0.5MM的范围内。<br style="overflow-wrap: break-word;"  /><br style="overflow-wrap: break-word;"  />2.4&nbsp; 扫描床机械系统的保养&nbsp;<br style="overflow-wrap: break-word;"  />为减轻机械系统的磨损,延长其使用寿命,需定期进行保养,添加润滑脂。&nbsp;<br style="overflow-wrap: break-word;"  />扫描采用的润没脂可与旋转轴承的润滑脂一致。&nbsp;<br style="overflow-wrap: break-word;"  /><br style="overflow-wrap: break-word;"  /><span style="overflow-wrap: break-word;font-weight: 700;">3.&nbsp; 球管冷却器的清洁&nbsp;<br style="overflow-wrap: break-word;"  /></span><br style="overflow-wrap: break-word;"  />每三个月用高压氧气或者气泵冲净冷却器内的灰尘和杂物。&nbsp;<br style="overflow-wrap: break-word;"  /><br style="overflow-wrap: break-word;"  /><span style="overflow-wrap: break-word;font-weight: 700;">4.其它</span>&nbsp;<br style="overflow-wrap: break-word;"  /><br style="overflow-wrap: break-word;"  />4.1每三个月检查清洁板箱风扇,顶罩风扇及各应急开关是否灵敏。</p><p style="white-space: normal;overflow-wrap:
