Haemodynamic and endothelium functions determining device for cardiac circulation system, has function testing unit directing shearing stress of flowing blood and releasing agent of endothelium-facilitated circulation of nitrogen monoxide

摘要

The device has a position unit to position a blood pressure- holding sleeve at extremities e.g. upper/lower arm of an individual. An opening unit opens compression pressure after a stasis-congestion time of 5-10 minutes. A function testing unit directs shearing stress of the flowing blood on a vascular wall through stimuli and releases the agent of endothelium-facilitated circulation of nitrogen monoxide. An independent claim is also included for a method of operating a device for determining haemodynamic functions of an endothelium function in blood vessel system and cardiac circulation system.
