Abstract
The present invention relates to devices and methods for measuring vascular deficiency using Doppler ultrasound detection. Embodiments can be used to monitor the condition of surgical tissue flaps or other conditions in which obstruction in the vascular system can impact patient health. The systems can include a Doppler ultrasound probe, a color probe, a temperature probe, and/or other suitable probes to measure blood volume and perfusion status of a tissue region. The systems and methods can be used to monitor flaps after flap transplant surgeries. The systems and methods can automatedly assess tissue condition and alert the patient or medical staff if the condition has fallen below a threshold indicating occlusion of a blood vessel. One or more additional sensors can be integrated into a probe to measure vascular conditions and a metric can be computed based on sensed data.
