Abstract

A miniature extraluminal force transducer has been developed and used to record acute and chronic motility of the reproductive tract in the rabbit. This device, which contains two matched piezoresistive silicon sensors bonded to a titanium beam strip, is durable, physically stable, and highly sensitive to bending force (gage factor, 140). Acute recordings made in 20 rabbits revealed continuous, rhythmic contractile activity in both the oviduct and uterus. Chronic recordings made in three unanesthetized rabbits revealed periodic bursts of intense activity interspersed with periods of relative quiescence. Chronic implantation of these devices was accomplished with no evidence of infection, adhesions, or other abnormalities, and without disruption of fertility.

摘要

一种微型腔外力传感器已被研发出来，并用于记录兔子生殖道的急性和慢性运动情况。该装置包含两个匹配的压阻式硅传感器，它们被粘结到一条钛梁带上，耐用、物理性能稳定，并且对弯曲力高度敏感（应变系数为140）。在20只兔子身上进行的急性记录显示，输卵管和子宫都有持续、有节律的收缩活动。在3只未麻醉的兔子身上进行的慢性记录显示，有周期性的强烈活动爆发，其间穿插着相对静止期。这些装置的慢性植入未出现感染、粘连或其他异常迹象，也未影响生育能力。
