Integrated uterine orifice and fetal head position measuring device

Abstract

The invention discloses an integrated uterine orifice and fetal head position measuring device which comprises a vaginal speculum assembly, the vaginal speculum assembly comprises two blades matched with each other, the tail ends of the two blades are hinged to each other to form an oval hole, a measuring rod seat is detachably arranged in the oval hole, a depth ruler is arranged on the measuring rod seat in a sliding mode. A light source adjusting rod is further arranged on the measuring rod base in a sliding mode, a uterine orifice measuring light source is arranged on the light source adjusting rod, the center line of a light beam emitted by the uterine orifice measuring light source coincides with the center line of the oval foramen, the light beam emitted by the uterine orifice measuring light source is emitted out along a fixed emergence angle, and a first depth scale is arranged on the depth ruler. And a second depth scale is arranged on the light source adjusting rod. The device has the advantages that the position of the fetal head and the size of the cervix can be measured at the same time, the natural size of the cervix is measured in a non-distraction mode, measured cervix data are more real and reliable, and measurement discomfort is reduced.

Description

technical field [0001] The invention belongs to the field of obstetrics and gynecology medical instruments, and in particular relates to an integrated cervix and fetal head position measuring device. Background technique [0002] During the delivery process of pregnant women, as the delivery process progresses, the cervix gradually opens and the head of the fetus gradually descends. Doctors and midwives judge the delivery process based on this. For the observation of the size of the cervix and the position of the fetal head, the most widely used clinical method is rough judgment by palpation. The doctor or midwife puts fingers into the birth canal, and according to how many fingers the cervix can accommodate, several "finger widths" are used as the division standard for the size of the cervix. The position of the fetal head is judged based on the position of the ischial tuberosity, and the approximate degree of fetal head descent can be roughly judged according to the lengt...

Problems solved by technology

Chinese patent document CN201910149623.8 discloses a device and method for detecting the degree of cervical dilation during labor. Based on image acquisition, recognition and data processing methods, the cervical os image, fetal presentation image and ischial spine anatomical position image are measured, and then Use software to process the image to obtain the data of the size of the cervix and the position of the fetal head. Although the device can measure the size of the cervix in a natural state and avoid the disadvantages of the aforementioned stretching measurement device, the overall device is relatively complicated and is not suitable for clinical promotion.
