摘要
目的 :介绍一种离体血管环的实验装置和方法。 方法 :通过心桥软件将血管环的等长张力和内壁周长数据绘成长度 张力曲线 ,据此将血管环拉伸至最适长度后进行实验。 结果 :本实验装置和方法稳定、可靠、准确、灵敏。 结论 :这套装置能够更准确地反映血管的特点 ,可用于各种血管环实验。
Objectives:An apparatus and method for the experiment of vessel ring ex vivo was discussed. Methods: Individual length tension curves for each vessel ring were established via coropass software by relating the isometric tension with the corresponding internal circumferential length. The vessel ring was investigated after being set at an optional point according to its own length tension curve. Results:The apparatus and method was stable, exact and sensitive. Conclusions: The apparatus and method reflected the properties of vessels more accurately and therefore was suitable for the experiment of all types of vessel rings.
