摘要：
Devices and methods for non-invasive capillary blood pressure measurement are provided. An device can comprise a front end in contact with the body to compress and decompress the capillaries in the tissue, a pressure control module for regulating the contact pressure between the front end and the tissue, a pressure transducer coupled to the front end for measuring the contact pressure, a capillary sensing module for detecting the capillaries pulsations under the contact pressure modulation, and an algorithm for determining the capillaries pressures from the traces of capillary pulsation signals and the contact pressure signal. The methods include an oscillometric method for intermittent arterial and capillary blood pressure measurement and a volume-clamp method for continuous capillary blood pressure measurement.
