A limit adjustment box is arranged under the body, sliding rollers are fitted in the sliding track, and a movement limit rod is arranged at the right end of the rod body of the length adjustment rod. The present invention changes the occurrence of serious error problems caused by the instability of traditional hand-held measuring rulers. The clamping effect is stable, the measurement operation process is simple and convenient, and the measurement values ​​are accurate, which meets the needs of most pregnant women and ensures the safety of babies. was born smoothly.

Description

technical field [0001] The invention relates to the related technical field of medical devices, in particular to a pelvic measuring ruler for obstetrics and gynecology. Background technique [0002] The Department of Obstetrics and Gynecology mainly studies the etiology, pathology, diagnosis and prevention of female reproductive organ diseases, the physiological and pathological changes of pregnancy and childbirth, the prevention, diagnosis and treatment of high-risk pregnancy and dystocia, female reproductive endocrinology, family planning and women's health care, etc. When the fetus is delivered from the mother, it must pass through the pelvis.

AI Technical Summary

Problems solved by technology

For primigravidas and pregnant women with a history of dystocia, pelvic measurements and examinations should be routinely performed during the first prenatal examination. A measuring ruler is needed in the process of measuring the pelvis of pregnant women, but in the past, the measuring ruler was usually taken by a doctor. Randomly placed on the hand, this form of operation is likely to cause serious errors due to the instability of the placement. The measured value is far from the actual value, which cannot provide auxiliary conditions for subsequent accurate measurement. During the limit measurement process, the mobile limit lever on the left will also have the problem of shaking and instability from side to side. The indication operation of the scale is cumbersome and complicated, and it cannot limit the pelvic requirements of pregnant women of different sizes. It needs to be improved.
