DESCRIPTION (Adapted from the applicant's abstract): Fetal monitoring is useful in assessing the progress of labor and for detection of preterm labor, a leading cause of fetal mortality and morbidity.Commercially available sensors for monitoring intrauterine contractions use cumbersome belts and large and bulky sensors which are uncomfortable and limit the patient's mobility. A small and simple self-adhering intrauterine pressure monitor has been developed. The sensor consists of an air-filled semi-rigid-walled disposable bubble that is attached to the abdomen by an adhesive and presses slightly into the abdominal wall so that changes in intrauterine pressure can be measured. The device demonstrates an excellent correlation when compared to a commercial tocodynamometer for the measurement of contraction duration and frequency. Once the design is optimized, it is expected that the disposable bubble monitor will be a commercial success because of the convenience of attachment, lower noise, greater comfort, lower cost, and convenience afforded to the nurse and to the patient.

描述（改编自申请人的摘要）：胎儿监测是 有助于评估分娩进展和检测早产 分娩是胎儿死亡和发病的主要原因。商业 用于监测宫内宫缩的可用传感器使用起来很麻烦 皮带和大而笨重的传感器不舒服并且限制了 患者的活动能力。 一种小型且简单的自粘式宫内压力监测器已问世 发达。 该传感器由一个充气的半刚性壁组成 一次性气泡通过粘合剂附着在腹部 轻微压入腹壁，使宫内发生变化 可以测量压力。 该器件表现出出色的相关性 与测量的商用生育力计相比 收缩持续时间和频率。 设计优化后， 预计一次性气泡监测器将取得商业成功 由于连接方便、噪音更低、舒适度更高， 成本更低，为护士和患者提供便利。
