Description
Technical field
This utility model relates to a kind of department of obstetrics and gynecology medical instruments, particularly a kind of department of obstetrics and gynecology basin bone aperture measurement device.
Background technology
In the clinical practice, to carry out the pelvis aperture measurement usually,, rule of thumb judge by the doctor usually at present, thereby error be bigger, be difficult to accurately judge anemia of pregnant woman's production time, delay anemia of pregnant woman's production owing to there is not special gauge for just before giving birth women.
Summary of the invention
The problem that this utility model will solve is: a kind of simple in structure, the department of obstetrics and gynecology basin bone aperture measurement device that can accurately measure the pelvis aperture is provided.
In order to solve the problems of the technologies described above; The department of obstetrics and gynecology pelvis aperture measurement device of this utility model; Comprise ruler, be fixed on the fixation measuring arm and the slip gage beam of ruler one end, said slip gage beam is provided with a chute, and said ruler is inserted in the chute; Said slip gage beam is provided with a tight fixed bolt, and said ruler is provided with the length scale.
For fear of when measuring, stabbing or the twinge anemia of pregnant woman, the department of obstetrics and gynecology pelvis aperture measurement device of this utility model, the top of said fixation measuring arm is a cambered surface, the top of said slip gage beam also is a cambered surface.
For the ease of controlling, the department of obstetrics and gynecology pelvis aperture measurement device of this utility model, the below of said ruler is provided with a grip.
The beneficial effect that this utility model is obtained is: (1) is simple in structure; (2) the fixation measuring arm is abutted against an end of pelvis, move the slip gage beam then, the slip gage beam is abutted against an other end of pelvis; The reuse tight fixed bolt is fixed the slip gage beam; Can read the numerical value of pelvis aperture from the ruler, thus easy to use, and accuracy of measurement is high; (3) top of fixation measuring arm and slip gage beam is cambered surface, thereby can avoid stabbing in the measuring process or the twinge anemia of pregnant woman; (4) below of ruler is provided with a grip, thereby is convenient to hold the whole measuring measuring device.
Description of drawings
Fig. 1 is the structural representation of this utility model.
Fig. 2 is the cutaway view of A-A face among Fig. 1.
Among the figure: 1, length scale, 2, the slip gage beam, 3, tight fixed bolt, 4, the fixation measuring arm, 5, handle, 6, chute, 7, ruler.
The specific embodiment
As depicted in figs. 1 and 2; The department of obstetrics and gynecology pelvis aperture measurement device of this utility model; Comprise ruler 7, be fixed on the fixation measuring arm 4 and the slip gage beam 2 of ruler 7 one ends, said slip gage beam 2 is provided with a chute 6, and said ruler 7 is inserted in the chute 6; Said slip gage beam 2 is provided with a tight fixed bolt 3, and said ruler 7 is provided with length scale 1; The top of said fixation measuring arm 4 is a cambered surface, and the top of said slip gage beam 2 also is a cambered surface; The below of said ruler 7 is provided with a grip 5.
In the time of concrete the use, fixation measuring arm 4 is abutted against an end of pelvis, move slip gage beam 2 then; Slip gage beam 2 is abutted against an other end of pelvis; Reuse tight fixed bolt 3 is fixing with slip gage beam 2, because ruler 7 is provided with length scale 1, can read the numerical value of pelvis aperture from the ruler 1; Thereby this utility model is easy to use, and accuracy of measurement is high.
The department of obstetrics and gynecology pelvis aperture measurement device of this utility model, the top of fixation measuring arm 4 and slip gage beam 2 is cambered surface, thereby can avoid when contacting with anemia of pregnant woman's pelvis, stabbing or the twinge anemia of pregnant woman.
This utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of under the enlightenment of this utility model, making, every with the utlity model has identical or close technical scheme, all fall within the protection domain of this utility model.
