Abstract
A head obstetric apparatus for obsterics belongs to the technical field of medical appliances, and is characterized in that a piston with a draw bar is slidably encapsulated and sleeved in a sleeve, the front end of the sleeve is communicated with a sucking disc, a sliding sleeve has the external diameter matched with the external diameter of the sleeve, and is slidably sleeved outside the sleeve, the two sides of the outer wall of the sliding sleeve are respectively and rotatably connected with symmetrical expansion pieces, and the middle parts of the inner sides of the two expansion pieces are respectively and rotatably connected with support rods which are rotatably connected onto the two sides of the outer wall of the front end of the sleeve; a support spring is sleeved on the sleeve between the front end of the sliding sleeve and an annular projection on the outer wall of the front end of the sleeve, and the rear end of the sleeve is contacted and connected with a limit nut which is threaded with the upper side of the rear end of the sleeve. The head obstetric apparatus for obsterics provided by the utility model has a simple structure, and is safe and convenient to use, the rotary limit nut can control the opening or closing of the expansion pieces, so the expansion of an obstetric canal pelvic floor is realized, and the head of a fetus is sucked by the negative pressure when the piston is pulled, so quick parturition is realized.
Description
Technical field
This utility model belongs to technical field of medical instruments, and specifically a kind of obstetrics use a head position borning aided device.
Background technology
At present, the used head position practise midwifery apparatus of department of obstetrics and gynecology has obstetric forceps and fetal head vacuum extractor, and this class midwifery device has been brought into play important function in the practise midwifery operation, but the problem that exists is: operate careless slightly, will cause damage to fetal head, when serious intracranial hemorrhage might take place.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of obstetrics to use a head position borning aided device, and it can be expanded at the bottom of the birth canal basin, reduces the resistance to fetal head, makes things convenient for fetus to give birth to fast.
The purpose of this utility model is achieved in that these obstetrics are made up of sucker, sleeve, piston, pumping rod, sliding sleeve, expanding plate, support spring, stop nut with head position borning aided device, the sleeve inner slipper seal suit that front end is connected with sucker the piston that has pumping rod, sleeve slide outside suit the sliding sleeve that internal diameter and sleeve outer diameter adapt, the sliding sleeve outer wall both sides symmetrical expanding plate that is being rotationally connected respectively, two expanding plate middle inside are rotationally connected with the support bar that is rotatably connected on above the barrel forward end outer wall both sides respectively; Sliding sleeve front end and be with support spring on the sleeve between the annular protrusion above the barrel forward end outer wall, the sliding sleeve rear end is connected with the stop nut contact that sleeve rear end is threaded above.
Advantage of the present utility model: simple in structure, safe in utilization, convenient, the rotary spacing nut is opening of may command expanding plate or closes up, thereby realizes that to the expansion at the bottom of the birth canal basin pulling piston can hold fetus head by negative pressure gives birth to fetus fast.
Description of drawings
Accompanying drawing is a structure cutaway view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail: these obstetrics use head position borning aided device by sucker 1, sleeve 2, piston 3, pumping rod 4, sliding sleeve 5, expanding plate 6, support spring 7, stop nut 8 is formed, the sleeve 2 slides within sealing suit that front end is connected with sucker 1 piston 3 that has pumping rod 4, sleeve 2 slide outside suits the sliding sleeve 5 that internal diameter and sleeve 2 external diameters adapt, sliding sleeve 5 outer wall both sides 6, two expanding plate 6 middle inside of symmetrical expanding plate that are being rotationally connected respectively are rotationally connected with the support bar 9 that is rotatably connected on above the sleeve 2 front end outer wall both sides respectively; Sliding sleeve 5 front ends and be with support spring 7 on the sleeve 2 between the annular protrusion 10 above the sleeve 2 front end outer walls, sliding sleeve 5 rear ends are connected with stop nut 8 contacts that sleeve 2 rear ends are threaded above.
