Technical Field
[0001] The utility model belongs to the technical field of medical auxiliary equipment, and more specifically relates to a measuring tape for production inspection. Background Art
[0002] At present, for the appearance examination of the pregnant woman's uterus, an ordinary measuring tape or tape is generally used to measure the pregnant woman's abdominal circumference and uterine height. That is, by measuring the uterine height and abdominal circumference, the gestational age can be preliminarily determined, so as to indirectly understand the growth and development of the fetus and estimate the fetal weight. Therefore, pregnant women need to measure the uterine height and abdominal circumference during each prenatal check-up to observe the fetal development in a timely and preliminary manner.
[0003] However, ordinary measuring tapes or tape measures only have some standard distance scales. After measuring the value, medical staff need to find the gestational age corresponding to the measured value according to the comparison table. The gestational age cannot be known at the same time of measurement, and the detection efficiency is low. Some hospitals require medical staff to memorize the comparison table, which is difficult for novice nurses. They still need to use the comparison table frequently during actual measurement, and the early learning efficiency is low. Utility Model Content
