| 摘 要： | 探讨胎儿脐带静脉随胎龄变化的生物力学特性的改变，为临床挑选适当的血管代用品提供理论依据。方法：33例新鲜脐带静脉，用生物软组织力学试验机测定血管的压力、容积、外径等力学参数，计算出弹性模量、顺应性。结果：37－40周时脐静脉的P－V曲线比较高，弹性模量与血压的关系曲线较低，此时段顺应性最好。结论：建议选用胎龄在37－40 周之间的脐静脉作为移植材料。 |
| 关 键 词： | 脐静脉 胎龄 顺应性 生物力学 |

| Abstract: | Objective:To study the biomechancial properties of human umbilical cord vein with aging changes and to pro-vide theoretic evidence for clinic in collecting suitable blood graft.Method:33fresh human umbilical cord vein s were collected.The parameters such as pressure,diameter and capacity of blood were also tested,then the com-pliance and elastic mudules were calculated.Result:The P-V curve are highest in37-40weeks while that of elatic mudules are lower,so compliance are best in this period.Conclusion:the author suggest that the umbili-cal vein in37-40weeks should be selected as graft material. |
| Keywords: | Human umbilical cord vein Gestional aging Compliance |
