摘要
目的 :研制出一种准确、可靠、高效的颈动脉压迫训练仪器 ,并通过动物实验证实其可行性和有效性。方法 :利用现有的皮肤扩张器生产工艺 ,结合人体颈动脉的具体解剖特点设计生产了植入式颈动脉压迫训练器 ;然后对其进行理化性能测定以及动物实验研究 :1对植入式颈动脉压迫训练器各部件的机械强度进行了测量 ;2对该仪器注水压与犬颈动脉内血流通通畅率之间关系进行了测量 ;3利用影像学手段观察证实了犬颈动脉被该仪器阻断情况。结果 :1植入式颈动脉压迫训练器对颈动脉断流可以提供足够的压力 ;2从注水压与犬颈动脉内血流畅率之间关系曲线观察到了颈动脉血流阻断特点 ;3以颈动脉造影的手段证实该仪器可以对颈动脉进行断流。结论 :植入式颈动脉压迫训练器能准确、可靠、安全的阻断颈动脉血流 ,达到颈动脉压迫训练的目的。
objective: To develop an accurate, reliable and efficient carotid artery compression training device .Methods:Adopting present technology for production of skin dilators in combination with anatomical characters of human carotid artery, an implantable carotid artery training occluder (ICATO) was designed and manufactured. The mechanical properties were tested and the carotid artery occlude effect was investigated in 12 dogs. Results: The expansion stress of the water cyst and duct of the occluder was 40 kPa, that of the water imput valve 30 kPa,tear stress of the nylon cloth was 5 kg. The carotid artery could be completely blocked at the pressure of 19 kPa produced by the occluder. Conclusion: ICATO can obstruct carotid artery for the purpose of compression training of carotid artery.
