The invention relates to an experimental device for medical function and
physiology, in particular to an improved experimental device for frog heart
perfusion. The improved experimental device comprises a buffer tube, a three-way buffer
artery tube, an
artery plug, an
artery cannula, a quantitative drop device, a
venous cannula and a venous plug, wherein an opening is formed in the top of the buffer tube; the three-way buffer artery tube is connected with the buffer tube; the artery plug is connected with one
branch tube of the three-way buffer artery tube; the artery cannula is connected with the other
branch tube of the three-way buffer artery tube; the quantitative drop device is connected with the artery cannula; the
venous cannula is arranged below the quantitative drop device; the venous plug is connected with the
venous cannula; the artery plug is inserted into an
aorta of a frog heart; the venous plug is inserted into a postcaval
vein of the frog heart. According to the improved experimental device for the frog heart
perfusion, disclosed by the invention, the buffer action for perfused liquid ejected in the blood ejection process of the frog heart is realized, uninterrupted dropwise outflow of the perfused liquid can be kept, the perfused liquid can flow at the
systole and
diastole of the heart, and quantitative
record of liquid can be realized by the quantitative drop device.
