Non-invasion-type detection instrument and method for cerebral blood oxygen of fetus in abdomen

Abstract

The invention discloses a non-invasion-type detection instrument and method for the cerebral blood oxygen of a fetus in the abdomen. The detection instrument comprises a probe and a control device, the probe completely fits the abdomen of a pregnant woman and is provided with a luminous source and multiple light sensing points, when light emitted by the luminous source penetrates through the front-wall tissue of the abdomen of the pregnant woman, the shallow-layer tissue of the head of the fetus and the cerebral tissue of the fetus, corresponding emergent light is formed, and the light sensingpoints detect the emergent light corresponding to the light sensing points; the control device is internally provided with a central processing module, a power module, an optical source driving module, a light sensing point signal receiving module and a data displaying module, and the power module, the optical source driving module, the light sensing point signal receiving module and the data displaying module are electrically connected with the central processing module; the optical source driving module controls the luminous source to give out light, the light sensing point signal receivingmodule receives light sensing signals of the light sensing points, and after the central processing module conducts data processing, a cerebral blood oxygen saturation degree value is obtained and displayed by the data displaying module. By adopting a noninvasive detection mode, the detection instrument can be applied to timely evaluation on the cerebral oxygen condition of the fetus in the abdomen, and the situation is avoided that due to events such as the cord around neck, the encephalic hypoxic-ischemic state is caused.

Description

technical field [0001] The invention relates to the technical field of fetal cerebral blood oxygen detection equipment, in particular to a non-invasive abdominal fetal cerebral blood oxygen detection instrument and a method thereof. Background technique [0002] Fetal distress is a syndrome in which the fetus has signs of hypoxia in utero and endangers the health and life of the fetus. If pregnant women have heart disease, diabetes, severe anemia, high blood pressure, nephritis, asthma, expired pregnancy and other diseases during pregnancy, or because of vascular lesions that reduce uterine blood, or because of reduced placental function, or because of low blood oxygen concentration, etc. If the fetus does not get enough oxygen, it will cause fetal growth retardation, polycythemia, decreased fetal movement, and even fetal death in severe cases. This is one of the leading reasons for cesarean deliveries today. The incidence of fetal distress was 2.7% to 38.5%. Mainly occur...

Problems solved by technology

However, invasive detection methods will undoubtedly bring complications such as trauma and infection to the fetus. There is an urgent need for non-invasive and convenient fetal brain oxygen detection methods in clinical practice.
