This paper presents a humerus arterial bleeding simulation model (HABSM) for hemostasia,which has a high-fidelity, practical model for the humerus arterial hemostasia operation that is not only for the surgeons and nurses, but also for commons in urgent bleeding accident. The functional components of HABSM are arm model, fluid circulated pipeline and circuit controlling system. The arm model is made of elastic material as human muscle. Fluid circulated pipeline contains wiggly pump, inlet pipe and outlet pipe. And circuit controlling system has single chip micyoco system (SCM), keyboard, pressure sensor and vision circuit. SCM controls pump and valve to realize humerus arterial blood circulation. Both surgeons and commons thought well of HABSM which provided a task trainer for humerus arterial hemostasia.展开更多
目的对比不同峰值负压超声联合微泡对脾创伤的止血效果。方法将15只家犬开腹建立脾创伤模型后,随机分为3组,治疗前记录各组10 s出血速率,然后经股静脉推注等量微泡后,分别以高(4785 k Pa)、中(3439 k Pa)、低(1785 k Pa)峰值负压脉冲超...目的对比不同峰值负压超声联合微泡对脾创伤的止血效果。方法将15只家犬开腹建立脾创伤模型后,随机分为3组,治疗前记录各组10 s出血速率,然后经股静脉推注等量微泡后,分别以高(4785 k Pa)、中(3439 k Pa)、低(1785 k Pa)峰值负压脉冲超声辐照6 min,分别记录各组治疗后10 min总出血量。结果治疗前各组出血速率无统计学差异(P>0.05);治疗后,各组10 min总出血量均有统计学差异(P<0.01),其中高峰值负压组最少,中峰值负压组次之,低峰值负压组最多。治疗后,超声造影显示低峰值负压组治疗区造影浅表局部有充盈缺损,大部分辐照区仍有造影剂充填;中峰值负压组可见辐照区大部充盈缺损,局部可见零星造影剂灌注;高峰值负压组可见治疗区基本无造影剂充填,呈充盈缺损。结论高峰值负压脉冲超声联合微泡治疗脾出血更加快速、彻底。展开更多
