When user wants a kind of obstetrics' sucker midwifery device using the present invention, the first step, precheck device
All parts assembling it is whether secured, whether detection device being capable of normal use；Second step is capable of normal use in device
In the case of used, sucker 3 is gently covered on the head of child, handwheel disk 2201 is rotated clockwise so that main shaft 2204 with
Handwheel disk 2201 rotate while drive the first driving gear 2205 rotate, to the first driving gear 2205 drive it is orthogonal
The first driven gear 2203 rotation of engagement, so that countershaft 2208 drives the second driving gear 2209 while linkage
Rotation drives worm screw 2303 to revolve while the second driven gear 2302 is rotated with the second driving gear 2209 being meshed therewith
Turn, to which the worm gear 2304 for driving lower section to be meshed with worm screw 2303 rotates, first rotating shaft 2308 rotates same with worm gear 2304
When third driving gear 2309 is linked, to drive the third driven gear that is meshed with third driving gear 2309
2306 rotations, third driven gear 2306 drive the rotation of the second shaft 2307, auxiliary of the third shaft 2407 in transmission belt 2305
It is rotated with the second shaft 2307 under transmission, and then rotating disk 2402 is driven to rotate, rotating disk 2402 drives static in contrast
Fixed link 2404 rotates, and makes mobile bar 2401 with the fixed link 2404 moved in contrast in the guiding role of looping pit 2405
Rotation and move horizontally, and by auxiliary movable pulley 2406 and sliding slot guide rail 2105 effect, exerted a force by connecting rod 2403
In motion bar 2501, by the auxiliary of movable pulley 2105 while motion bar 2501 is moved with mobile bar 2401 so that motion bar
2501 act on handle 2404 by movable span 2405, so that handle 2404 drives I-shaped volume static in contrast to put frame
2502 with the 4th shaft 2506 for circular rotating, and then discharge steel wire rope 2603, the steel wire rope 2603 of release is reduced to resetting
The pulling force of spring 2704 provides power due to be resetted by compression for resetting spring 2704, to act on telescopic rod 2705, makes
It is overhanging to sleeve 2702 to obtain telescopic rod 2705, and then pushing plate 2706 is extrapolated so that piston rod 7 is overhanging to piston cylinder 4, sucker
At negative pressure, the pressure responsive element induction pressure on piston rod 7 checks pressure value by pressure gauge 6, works as arrival for air in 3
When convenient pressure value, stop the rotation of handwheel disk 2201, grasp position of the piston cylinder 5 with anti-skidding raised line 5, by child to production
It is drawn outside road junction, child smoothly after production, checks clock 1, and make record.
Problems solved by the invention is the prior art since technology is not perfect, in use, straight by medical worker
It connects and pull rod is pulled to form negative pressure in sucker to carry out midwifery, since different medical worker's self-techniques and experience are different,
When easily causing medical worker's childbirth midwifery, to pull rod undue force, the limbs of newborn baby's fragility can be hurt, the present invention passes through above-mentioned portion
Part is combined with each other, and piston rod is enabled to slowly to be drawn toward outside piston cylinder, can effectively avoid experience and the different medical matters of technology
Personnel exert oneself excessive direct pull piston rod, avoid forming excessive negative pressure in sucker so that can be very big when giving a birth midwifery
Guarantee mother and child safety, so as to preferably serve gynemetrics's production operation.
