Different phase, the requirement to negative pressure is also different, if all using traditional vacuum extractor, adaptability regulating power is poor,
It can not realize that the patient to different pregnancy cycles and the different phase in operation implement specific Xi Palace negative-pressure operations, so using
Traditional vacuum extractor often excessively inhales Palace and causes endometrial impairment or lead to incomplete abortion.In addition, traditional negative pressure is inhaled
The great Xi Palace negative pressure of its cylinder of Palace devices is about 375mmhg, can be only applied to the patient of 5-7 weeks unexpected pregnancy, can not adapt to
The patient of 8-10 weeks unexpected pregnancy is used, because its great Xi Palace negative pressure is still reached to less than associated specifications.
The problem of the second aspect；Traditional vacuum extractor employs the valve that inclined-plane limits and stucks and designs (i.e. referring to special
Profit is application No. is a kind of 200920158735.1 needle tube type manual vacuum extractor structure, the switch key with lock
(i.e. valve mechanism) is worn biography and is sleeved in opening, under shed is blocked by the bottom protrusion inclined-plane of switch key across under shed,
Implement closing), but this traditional valve valve design door locking stability and reliability are poor, easily come off, cause valve
Negative pressure is locked unstable；Meanwhile medical worker is easy to accidentally run into valve and inclined-plane card is caused not live, valve is sprung back at this time,
Moment becomes positive pressure by negative pressure, and the hydrops just absorbed will be quickly returned to intrauterine together with air, on endometrium
Blood vessel, endometrium etc. damage, serious conditions will lead to air embolism, jeopardize patient vitals' safety.It is so traditional
Vacuum extractor, negative pressure Locked valve poor reliability, leads to vacuum extractor safety issue.
The problem of in terms of third：Its internal pull rod bolt of traditional vacuum extractor, is carrying out vacuum suction embryonic tissue
When pull rod bolt will be drawn out certain distance, medical worker is easy to touch pull rod bolt in operation, causes pollution；Multidigit is cured
Raw also all its pull rod bolt length is long in operation for the traditional vacuum extractor of reflection, is not only awkward, but also easily make pull rod bolt, hand
Touching clothes in the part such as handle leads to have bacterium pollution, therefore how to design instrument total length when reduction operates, and will be one crucial
Technical barrier.
The problem of 4th aspect：Above-mentioned tradition vacuum extractor its use single valve structure design and be pushed forward after pressing or
The mode of operation of retrogressing, doctor are not only not easy to switch, and also easily accidentally encounter valve in operation, cause negative pressure catastrophic failure, draw
The accident of rising.
