Problems solved by technology

In addition to the soft birth canal composed of the uterus, cervix, vagina and vulva, the pelvis is the most important part of the birth canal; the speed and smoothness of childbirth are closely related to the size and shape of the pelvis. Deformed pelvis can cause dystocia. Primigravidas and pregnant women with a history of dystocia should routinely measure and check the pelvis during the first prenatal examination. The pelvic measuring instrument currently used has a single function and can only measure the inner diameter of the pelvis unilaterally. Or outer diameter, in order to solve the above problems, a new technical solution is provided

Abstract

The invention discloses a pelvic measuring instrument for obstetrics, which comprises a cross arm, a fixing rod and a measuring rod. The cross arm is provided with a T-shaped chute, a scale line and a screw hole, and the T-shaped chute is opened on the cross arm. Above, the scale line is engraved on the front end of the cross arm, the screw holes are drilled on both sides below the T-shaped chute, and the screw holes are screwed with limit screws, the fixing rod is welded to the front end of the cross arm, and fixed The front end of the rod is provided with an elliptical block, and the measuring rod is installed above the T-shaped chute through the T-shaped slider, and the measuring rod and the T-shaped slider are welded together, and the front end of the measuring rod is provided with an elliptical block. The invention has the advantages of simple structure and convenient operation, and can easily measure the inner and outer diameters of the pelvis, and the measured dimensions are accurate.

Description

technical field [0001] The invention relates to a pelvic measuring instrument for obstetrics, which belongs to the technical field of medical instruments. Background technique [0002] When the fetus is delivered from the mother, it must pass through the pelvis. In addition to the soft birth canal composed of the uterus, cervix, vagina and vulva, the pelvis is the most important part of the birth canal; the speed and smoothness of childbirth are closely related to the size and shape of the pelvis. Deformed pelvis can cause dystocia. Primigravidas and pregnant women with a history of dystocia should routinely measure and check the pelvis during the first prenatal examination. The pelvic measuring instrument currently used has a single function and can only measure the inner diameter of the pelvis unilaterally. Or outer diameter, in order to solve the above problems, a new technical solution is provided. Contents of the invention [0003] The purpose of the present inventi...
