在妇科医学领域,获取女性子宫腔收缩形变及收缩频率等参数对医生了解女性的生理情况有着重要的意义。本文提出了一种用于测试该类参数的宫腔形变传感器,分析了传感器三个方向的受力变形情况。传感器具有柔软性、可伸缩性以及与宫腔形状的匹配性等特点,能够较容易地放入女性子宫腔内。通过实际测试,设计的传感器样品其左右组和上组线圈的灵敏度分别为22.38 nH/mm2和22.84 nH/mm2,传感器形变反应时间小于200 ms,满足测试子宫腔组织形变参数对灵敏度和反应时间的要求,传感器已应用于医学相关领域的测试与研究。
In the field of gynecology, getting the parameters of female uterine contraction and contraction frequency and other parameters is of great significance to the doctor to understand the physiological condition of the female. In this paper, we present a uterine deformation sensor for testing these parameters, and analyze the force and deformation of the sensor in three directions. The sensor has the characteristics of softness, scalability and matching with the shape of the uterine cavity, which can be easily put into the female uterine cavity. Through the actual test, the sensitivities of the left and right groups and the upper group of coils of the designed sensor sample are respectively 22.38 nH / mm2 and 22.84 nH / mm2, and the sensor deformation reaction time is less than 200 ms, which meets the requirements of testing the sensitivity of the uterine cavity tissue deformation and the response time Requirements, the sensor has been used in medical related fields of testing and research.
