Embodiment Construction

[0043] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0044] Such as figure 1 , 2 As shown in and 5, an integrated cervix and fetal head position measuring device includes a speculum assembly, and the speculum assembly includes two blades that cooperate with each other, namely a fixed blade 41 and a rotating blade 42. The sections of the fixed vanes 41 and the rotating vanes 42 are both in the shape of arc grooves, and the notches of the two are opposite to each other. The tail ends of the two blades are hinged to each other to form an oval hole, the tail ends of the two blades are connected with handles 43 respectively, and the front ends of the two blades are respectively provided with duckbills.

[0045] A measuring assembly is detachably arranged in the foramen ovale, and the measuring assembly includes a measuring rod seat, and an observation hole is left between the measuring rod seat and the inner wall ...

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...
