研制了一种用于测量人体水分平衡的手持式水合监测仪器。脱水是一个严重的公共卫生问题。许多65岁以上的老人和婴幼儿特别容易受到感染。鉴于脱水是可预防和可逆的，需要一种易于执行的方法来检测水分失衡是最重要的临床重要性。HM是基于一个实验事实，即肌肉中的超声波速度是含水量的线性函数，可以参考身体的水合状态。美国阿巴拉契亚州立大学（Appalachian State University）对居住在辅助生活设施的健康年轻人和老年人进行了HM评估全身水合状态的有效性研究。HM能够追踪运动员在急性脱水和补水期间体内总水分的变化，以及老年人每天和每天的水合变化。人体研究结果表明，HM有可能成为检测人体水合状态异常变化的有效工具。
An acoustical handheld hydration monitor (HM) for assessing the water balance of the human body was developed. Dehydration is a critical public health problem. Many elderly over age of 65 are particularly vulnerable as are infants and young children. Given that dehydration is both preventable and reversible, the need for an easy-to-perform method for the detection of water imbalance is of the utmost clinical importance. The HM is based on an experimental fact that ultrasound velocity in muscle is a linear function of water content and can be referenced to the hydration status of the body. Studies on the validity of HM for the assessment of whole-body hydration status were conducted in the Appalachian State University, USA, on healthy young adults and on elderly subjects residing at an assisted living facility. The HM was able to track changes in total body water during periods of acute dehydration and rehydration in athletes and day-to-day and diurnal variability of hydration in elderly. Results of human studies indicate that HM has a potential to become an efficient tool for detecting abnormal changes in the body hydration status.
