The aim of this report is to describe a new device that can validate, by automated auscultation, individual blood pressure (BP) readings taken by automated sphygmomanometers.The Accutension Stetho utilizes a smartphone application in conjunction with a specially designed stethoscope that interfaces directly into the smartphone via the earphone jack. The Korotkoff sounds are recorded by the application and are analyzed by the operator on the screen of the smartphone simultaneously with the images from the sphygmomanometer screen during BP estimation. Current auscultatory validation standards require at least 85 subjects and strict statistical criteria for passage. A device that passes can make no guarantee of accuracy on individual patients. The Accutension Stetho is an inexpensive smartphone/stethoscope kit combination that estimates precise BP values by auscultation to confirm the accuracy of an automated sphygmomanometer's readings on individual patients. This should be of great value for both professional and, in certain circumstances, self-measurement BP. Patients will avoid both unnecessary treatment and errors of underestimation of BP, in which the patient requires therapy. The Stetho's software has been validated in an independent ANSI/AAMI/ISO standard study. The Stetho has been shown to perform without difficulty in multiple deflation-based devices by many manufacturers.
本报告的目的是描述一种新的设备，该设备可以通过自动听诊自动验证自动血压计（BP）读数。Accutension 听诊器利用智能手机应用程序与专门设计的听诊器结合使用，该听诊器通过耳机插孔直接与智能手机接口。应用程序记录柯氏音，并由操作员在智能手机屏幕上与血压计屏幕上的图像同时进行分析，以进行 BP 估计。目前的听诊器验证标准要求至少有 85 名受试者，并满足严格的统计标准才能通过。通过验证的设备并不能保证对个别患者的准确性。Accutension 听诊器是一种廉价的智能手机/听诊器套件组合，通过听诊来估计精确的 BP 值，以确认自动血压计对个别患者读数的准确性。这对于专业人士和某些情况下的自我测量血压都将具有重要价值。患者将避免不必要的治疗和对 BP 的低估错误，在这种情况下，患者需要治疗。该听诊器的软件已在独立的 ANSI/AAMI/ISO 标准研究中得到验证。该听诊器已在许多制造商的多种基于放气的设备中进行了演示，没有任何困难。
