一种用于人体保健的新型磁呼吸传感器
A Novel Magnetic Respiratory Sensor for Human Healthcare
摘要：
呼吸对生命至关重要。因此，实时监测患者的呼吸模式对于呼吸康复治疗（例如，用于呼吸触发成像的磁共振检查、慢性肺病治疗和同步功能性电刺激）至关重要。虽然已经开发了许多呼吸设备，但它们通常与患者直接接触，这可能产生不准确或有限的数据。在这项研究中，我们开发了一种新型的、非侵入性的、非接触式的磁传感平台，可以精确地监测患者的呼吸、运动或睡眠模式，从而在诊所或家中提供有效的监测。磁-LC共振（MLCR）传感器将患者呼吸产生的磁振荡转换为阻抗谱，从而可以对呼吸变化进行深入分析，以识别与COVID-19相关的疾病。由于MLCR传感器的灵敏度高，它能为每一位受试患者提供不同的呼吸模式。该传感器还提供了在多个阶段的呼吸强度以及呼吸速率和幅度的异常变化的准确测量。这表明MLCR传感器可以检测患者因呼吸短促或呼吸困难而出现的COVID-19症状，并实时跟踪疾病进展。
英文摘要：
Breathing is vital to life. Therefore, the real-time monitoring of breathing pattern of a patient is crucial to respiratory rehabilitation therapies such as magnetic resonance exams for respiratory-triggered imaging, chronic pulmonary disease treatment, and synchronized functional electrical stimulation. While numerous respiratory devices have been developed, they are often in direct contact with a patient, which can yield inaccurate or limited data. In this study, we developed a novel, non-invasive, and contactless magnetic sensing platform that can precisely monitor breathing, movement, or sleep patterns of a patient, thus providing efficient monitoring at a clinic or home. A magneto-LC resonance (MLCR) sensor converts the magnetic oscillations generated by breathing of the patient into an impedance spectrum, which allows for a deep analysis of breath variation to identify respiratory-related diseases like COVID-19. Owing to its ultrahigh sensitivity, the MLCR sensor yields a distinct breathing pattern for each patient tested. The sensor also provides an accurate measure of the strength of breath at multiple stages as well as anomalous variations in respiratory rate and amplitude. This suggests that the MLCR sensor can detect symptoms of COVID-19 in a patient due to shortness of breath or difficulty breathing as well as track the progress of the disease in real time.
