TEST APPARATUS

PROBLEM TO BE SOLVED: To provide a test apparatus capable of precisely predicting a childbirth time that is difficult to estimate conventionally.SOLUTION: The test apparatus comprises: measurement means which measures a blood flow rate through a vein flowing from the placenta to the unborn child and a blood flow rate through arteries flowing from the unborn child to the placenta; arithmetic means which calculates energy variation on the basis of the blood flow rate through the vein and that through the arteries measured by the measurement means; and determination means which predicts the childbirth time of the unborn child on the basis of the energy variation.SELECTED DRAWING: Figure 1 【課題】従来技術では推定が難しかった分娩時期を精度良く予測できる検査装置を提供する。【解決手段】検査装置は、胎盤から胎児へと向かう静脈の血流速度と、前記胎児から前記胎盤へと向かう動脈の血流速度を測定する測定手段と、前記測定手段の測定した前記静脈の血流速度と前記動脈の血流速度とに基づいて、エネルギー変化量を演算する演算手段と、前記エネルギー変化量に基づいて、前記胎児の分娩時期を予測する判断手段と、を有する。【選択図】図１
