摘要
Methods for testing the survival of patients' tissues for anastomosis using perfusion measuring devices are described.The method isAt least one linear actuation structure of the perfusion measurement device is controlled;It can include rapidly increasing the force uniformly applied to at least one test area of the tissue selected for anastomosisThe force uniformly applied to the at least one test area isDefine local (systolic) perfusion pressure;And during the rise of the forceComputer isReceiving a sensor signal from at least one sensor of the perfusion measurement device and a signal from the blood pressure device;WhereThe sensor signal isBlood perfusion through the microvasculature in the first test areaThe blood pressure signal isIndicates the systemic (systolic) blood pressure of the patient during the elevation of the force;The sensor signalTo the computerIn the case of signal communication that said perfusion of the blood in said tissue of said first test area was stoppedThe computerControlling the working structure to slow down the force uniformly applied to the first test area;And during the descent of the forceIf the computer detects the initiation of blood perfusion through the microvessel,The computerDetermining the local perfusion pressure values and systemic blood pressure values to determine whether the tissue in the at least one test area can survive for anastomosisWhereThe calculated local perfusion pressure value isDefine the local reperfusion pressure value of the first test areaBased on the local reperfusion pressure value and the systemic systolic blood pressure value of the at least one test areaIncluding the prediction of whether the tissue in the at least one test area can survive for anastomosis.Diagram
