Abstract
The present invention relates to a real-time biosignal measurement apparatus for cardiac ischemia and reperfusion. The apparatus includes: a peristaltic pump which pumps perfusate from a tank storing the perfusate; a pressure trap which offsets the pulsation of both sides between a solution chamber temporarily storing the pumped perfusate and the perfusate tank; a heat exchanger to which the temporarily stored perfusate is applied and which transfers the heat of the perfusate; a bubble trap to which the heat transferred perfusate is applied on one side and which filters the heat transferred perfusate to transduce the perfusate to an isolated heart connected to the other side; a sensor unit which detects the gas concentration value in the myocardium of the isolated heart in real time during the cardiac ischemia reperfusion; and a control unit which is supplied with the gas concentration value in the myocardium of the isolated heart in order to analyze its correlation with the degree of a myocardial injury of the isolated heart.
