Problems solved by technology

After pregnancy, with the growth and development of the fetus, the uterus will gradually increase, so the distance between the electrodes varies from person to person and the gestational age. It is necessary to use a ruler to measure the distance between the electrodes. In actual operation, there are problems such as inaccurate measurement and inconvenience.

Embodiment 1

[0027] Such as figure 1 , taking 4 electrodes as an example, cover the flexible abdominal ruler on the surface of the pregnant woman's abdomen, and place the 0 point of the flexible scale at the 1 / 3 of the pregnant woman's left hip bone bump and navel. At the (62.5, 262.5), (187.5, 262.5), (62.5, 87.5) and (187.5, 62.5) of the abdominal scale, there are four scale holes with a radius of 25mm respectively, according to the specific position of the pregnant woman's uterus , adjust the four movable electrodes carried on the flexible scale to appropriate positions within the circular hole range of the scale, so that the four movable electrodes cover the entire uterus.

Embodiment 2

[0029] Such as figure 2, taking 8 electrodes as an example, cover the flexible abdominal ruler on the surface of the pregnant woman's abdomen, and place the 0 point of the flexible scale at the 1 / 3 of the pregnant woman's left hip bone bump and navel. (31.25, 218.75), (93.75, 262.5), (156.25, 262.5), (218.75, 218.75), (93.75, 131.25), (156.25, 131.25), (93.75, 43.75) and (156.25, 43.75) ) is the center of the circle, and there are 8 scale holes with a radius of 25mm. According to the specific position of the pregnant woman’s uterus, adjust the 8 movable electrodes carried on the flexible scale to the appropriate positions within the scope of the scale holes (5). , so that 8 movable electrodes cover the entire uterus.

[0030] Such as Figure 3-8 According to the size of the abdomen and uterus of the pregnant woman, pinch the fixing buckle (10) of the electrode fastening device (4), move the movable electrode (2) to a suitable position, loosen the fixing buckle, and fix the ...

Abstract

The invention relates to a flexible abdominal ruler for measuring electrode spacing, which belongs to the technical field of flexible abdominal rulers. Including flexible scale panel (1), movable electrode (2), positioning disc (3) and electrode fastening device (4); when in use, cover the flexible abdominal scale on the surface of the pregnant woman's abdomen, and pinch it tightly according to the size of the pregnant woman's abdomen The fixed buckle (10) of the electrode fastening device (4), moves the movable electrode (2) to a suitable position, loosens the fixed buckle, records the positions of the electrodes, and then calculates the distance between the electrodes. The invention has the advantages of convenient and quick operation, high measurement precision and accurate reading. Provide key data support for the study of the conduction information of uterine myoelectric signals.

Description

technical field [0001] The invention relates to a flexible abdominal ruler, in particular to a flexible abdominal ruler for measuring the distance between electrodes in the abdomen of a pregnant woman. Background technique [0002] Uterine contractions, that is, uterine contractions, directly promote the expulsion of the fetus from the mother, and are the driving force for childbirth. Uterine contraction is an important basis to reflect the delivery status of pregnant women, and uterine contraction monitoring is of great significance for ensuring maternal and fetal health. During the obstetric examination, uterine contractions are often monitored by the intrauterine pressure catheter (IUPC), the tocodynamometer (TOCO), and the doctor's palpation of the pregnant woman's abdomen. The IUPC method is to insert a catheter into the uterine cavity through the vagina, and use the sensor on the catheter to measure the intrauterine or amniotic fluid pressure, reflecting the uterine c...
