1.方法 1.1 止血带的使用 根据病区患者多少准备足量的止血带,要求多于日平均患者数10-15根,以备用。护士输液时,根据输液人数将止血带取出放入清洁干燥的容器内,置于治疗盘中，一人一止血带，使用后的止血带放入弯盘内，统一集中处理。 1.2 止血带的回收及处理 将使用后的止血带由科室自行清洗消毒改为消毒供应中心统一回收→浸泡于消毒液中→常水冲洗→加酶洗涤剂洗涤→专用长毛刷刷洗→常水冲洗→去离子水精洗→干燥箱干燥→用清洁包装袋包装→注明消毒日期、失效期、责任人→下送临床科室。每天更换。 2.结果 病区止血带连续使用1 h后未经任何消毒处理,病原菌检出率为100%,经科室自行消毒处理后病原菌检出率为5%,菌落数>15 CFU/cm2,且有致病菌存在。统一回收至消毒供应中心，清洗消毒后，经细菌培养 1～9 d，物体表面细菌总数≤5 cfu/cm2，均无致病菌生长。 3.讨论 在临床治疗护理中，止血带因使用频率高，与患者接触密切，大多重复使用，已成为医院内交叉感染的重大隐患。病区加强止血带的规范管理，切实做到一人一带一使用一消毒，而且通过消毒供应中心集中处理，保证了止血带的消毒质量，切断了致病菌的传播途径,从而有效地防止了交叉感染的发生。

Method 1.1 the use of a tourniquet in the area of the patient is 10 to 15 more than the average number of patients per day. Nurse transfusion, according to the number of infusion remove a tourniquet in a clean and dry container, in the treatment of plate, a person a tourniquet, after using a tourniquet in bending disc, a centralized processing. 1.2 a tourniquet recycling and processing Will use a tourniquet after disinfection supply center instead of the cleaning and disinfection of the department to the unified recycling - soaked in disinfectant - often water flushing to enzymatic detergent washing, special hair brush to wash to often water flushing, deionized water fine cleaning - drying oven drying - with clean bag packaging to indicate the disinfection date, expiry date, responsible persons, the clinical departments. Change every day. Tourniquet, ward 2. Results after continuous use 1 h without any disinfects processing, pathogen detection rate of 100%, after department to sterilize the pathogen detection rate was 5%, the colony count > 15 CFU/cm2, and the presence of pathogens. After cleaning and disinfecting, the total number of bacteria is less than 5 cfu/cm2, which is not pathogenic. 3. Discuss in clinical nursing, the tourniquet by using high frequency, close contact with patients, mostly repeated use, has become a major hidden danger of nosocomial cross infection. Strengthen the standard management of tourniquet, ward, cogent accomplish one area using a disinfection, and sterilization supply center centralized processing, ensure the quality of the disinfection of tourniquet, cut off the spread of pathogens way, so as to effectively prevent the occurrence of cross infection.
