There are few instruments specifically designed to measure circumferential force generated by ring segments of arteries in vitro. Typical limitations of some existing machines include poor isometry, large organ bath volume or difficult sample mounting. The authors designed, built and tested a device for isometric tension recording of force developed by rings of arteries in vitro. It is suitable for assessment of arteries from 0.3 to 3 mm in diameter and allows measurements of forces in the range 0-20 g on eight rings simultaneously. The organ baths are independently regulated in temperature, stirred, disposable and have a minimum useable volume of only 1.2 mL.
专门设计用于在体外测量动脉环段产生的圆周力的仪器很少。一些现有仪器的典型局限性包括等长性差、器官浴槽体积大或样品安装困难。作者设计、制造并测试了一种用于体外记录动脉环产生的力的等长张力的装置。它适用于评估直径为0.3至3毫米的动脉，并允许同时测量八个环上0至20克范围内的力。器官浴槽温度可独立调节、搅拌、一次性使用，最小可用体积仅为1.2毫升。
