An ischemic cardiopathy diagnosis assistance system includes pressure data acquisition meansfor acquiring pressure data including proximal pressure Pa in a proximal stenotic segment Aand distal pressure Pd in a distal stenotic segment A; intracoronary electrocardiogram data acquisition meansfor acquiring intracoronary electrocardiogram data made up of a local intracoronary artery electrocardiogram in a neighborhood of the distal stenotic segment; and computational processing meansfor finding a pressure ratio Pa/Pd between the proximal pressure Pa and distal pressure Pd at a time suitable for diagnosis of ischemic cardiopathy based on these data. The computational processing means temporally associates the pressure data with the intracoronary electrocardiogram data, estimates an analysis period T during which vascular resistance remains stably low from a waveform of the intracoronary electrocardiogram data, and extract the pressure data of the analysis period T, and finds the pressure ratio Pa/Pd from the pressure data.

Provided is an examination result estimation device that includes: a signal acquisition unit that acquires an electrocardiogram signal; an estimation unit that estimates an echocardiography result corresponding to the electrocardiogram signal acquired by the signal acquisition unit, by using a learned model obtained by machine learning using an electrocardiogram signal for learning as input data, and an echocardiography result as teacher data; and an output unit that outputs the echocardiography result estimated by the estimation unit.

Examination result estimation device, program, and program storage medium

A method is provided for collecting a small blood sample by painlessly puncturing a finger. When the skin of a human being is punctured by a needle or another device at the depth that does not exceed 0.5 mm, pain accompanying the puncture is diminished or decreased. Regardless of an error in the depth of the puncture, the depth of puncture must not exceed this depth. The puncture site is located on the dorsal surface of a finger, in the area from the finger joint (IP joint of thumb, DIP joint of fingers other than thumb) to the proximal nail wall and the area extending from the proximal nail wall to the lateral nail wall.
