Problems solved by technology

However, its operation still relies on the manual operation of doctors. Different doctors have different manipulation techniques and strengths, which will cause large deviations in measurement results.
In addition, it is necessary to put the measuring device in and out repeatedly to obtain each measurement result, which is cumbersome to use

Abstract

A cervical dilatation measuring device includes an air passage, a water passage, and a scale; the air passage is used for vacuuming to enable the measuring device to be adsorbed on the surface of an inner cervical mouth, the water passage is disposed in the air passage for providing a buffer and indicating a pressure change, the scale sleeves the air passage, the outer wall of the air passage is provided with a calibration, and the edge of the end of the scale cooperates with the calibration to indicate the degree of cervical dilation. The cervical dilatation measuring device can be used to measure cervical opening degree, is easy to use, can replace tactus and avoid individual deviations and inconsistencies of tactus, and does not require use of complex mechanical/electronic systems.

Description

technical field [0001] The invention relates to a device for measuring cervical dilation. Background technique [0002] Cervical dilation refers to the regular uterine contractions of pregnant women during labor, pulling the uterine muscles and surrounding fibers of the cervix, and the amniotic sac in front of the fetal presentation is wedge-shaped, resulting in the upward and outward expansion of the cervix. The tube gradually shortens until it disappears. The external os of the cervix is ​​usually only the size of a fingertip. As the labor progresses, the external os of the cervix expands to a diameter of 10 cm, which can allow the full-term fetal head to pass through. This process is also known as opening the cervix. [0003] The dilation process of the cervix is ​​relatively slow. It takes an average of 8 hours from labor to dilation of the cervix, and an average of 4 hours from dilation of the cervix to 6 cm to 10 cm. Under normal circumstances, some drugs for pain w...
