Fundal height and abdominal circumference measurement device

Abstract

The invention relates to a fundal height and abdominal circumference measurement device, which comprises expansion supporting rods, a rotating shaft, a torsion spring, operating handles, an arc lengthmeasuring ruler and a chord length measuring ruler. The expansion supporting rods are symmetrically mounted on the rotating shaft and capable of rotating around the rotating shaft; the torsion springis mounted on the rotating shaft and used for closing the supporting rods, the expansion supporting rods extend at the rotating shaft to form the two operating handles, and the expansion supporting rods are opened or closed through pressing and releasing of the operating handles. A scale of the arc length measuring ruler penetrates two top ends of the expansion supporting rods, scale graduation represents arc length corresponding to two top ends of the expansion supporting rods, and scale graduation of the chord length measuring rule represents a straight line distance of the two top ends ofthe expansion supporting rods. In performing of fudal height and abdominal circumference measurement on a pregnant woman, frequently moving the pregnant woman lying on back is avoided, and accordinglyantenatal examination efficiency can be remarkably improved, and discomfort in antenatal examination can be alleviated for the pregnant woman.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, and in particular relates to a measuring device for the height of the abdomen. Background technique [0002] Pregnant women need to measure the height and abdominal circumference of the uterus during the obstetric examination, and estimate the size, weight, and intrauterine development of the fetus based on this. Obstetrical inspectors need to pass the ruler around the back of the pregnant woman, and measure the largest circle around the abdomen as the abdominal circumference. Among the existing measurement methods, such as the Chinese patent (publication number: 1087805A, public date: 1994-06-15) palace height abdominal circumference measuring ruler, Chinese patent (authorized announcement number CN203776906U, authorized announcement date 2014.08.20) a palace The high abdominal circumference measurement device needs to move the pregnant woman many times in order to find the largest c...
