Description
Affiliated technical field
This utility model relates to a kind of obstetrics practise midwifery medical apparatus and instruments, particularly relates to a kind of vacuum indication of having, and the negative pressure warning lamp that transfinites is arranged, and relief valve is arranged, and has the most frequently used novel woman of a kind of obstetrist of fetal head protection sucker to produce vacuum extractor.
Background technology
Often need artificial practise midwifery when the puerpera produces, vacuum extractor is the practise midwifery apparatus that obstetrics often use.At present, traditional vacuum extractor that obstetrics use, no negative pressure indication, the suction size is wayward, and the woman produces the doctor and is difficult to grasp vacuum magnitude; The negative pressure deficiency, captivation is little, and the easy slippage of suction nozzle causes repeatedly to attract, and is unfavorable to puerpera and baby; Negative pressure is excessive, and captivation is big, causes fetal scalp impaired easily, cephalledema, the damage of fetus head such as intracranial hemorrhage.Common vacuum extractor because the suction nozzle geometry designs is unreasonable, when attracting, to not growing incorrect how much extruding of intact fetal skull as yet, causes the distortion of fetus cranium brain, damage, also happens occasionally.Therefore, how improving the scientific and technological content of medical level and obstetrics' medical apparatus and instruments of hospital for gynaecology and obstetrics, is the problem that medical personnel and scientific worker constantly study, inquire into, invent, innovate.
Summary of the invention
In view of the foregoing, this utility model provides a kind of vacuum indication of having, and the negative pressure warning lamp that transfinites is arranged, and relief valve is arranged, and the novel evacuated vacuum extractor of warning that transfinites of fetal head protection sucker is arranged; Its fetal head gravitation can show on vacuum meter that gravitation transfinites, and warning lamp is bright to be opened; After the fetus output, but the relief valve quick pressure releasing, and the shortening stages of labor of racing against time makes the suction pump practise midwifery reduce to minimum to mother and baby's side effect, fetal head gravitation is can be controlled in the scope of stable, safe, reliable, standard, to guarantee mother and baby's safety.
The technical scheme that the invention for solving the technical problem adopted is: the novel evacuated vacuum extractor of warning that transfinites, suction nozzle, holding rod, negtive-pressure implement are arranged, it is characterized in that: inner chamber (7) front end of taper suction nozzle (2) has the arc fetal head protection sucker (1) of the one that is tightly connected with it, suction nozzle inner chamber (7) rear end has suction nozzle to connect microcephaly (8), and fetal head protection sucker (1) has a plurality of negative-pressure balancings hole (6); Suction nozzle connects microcephaly (8) has connection rib-loop (3) to be connected with holding rod (4), and handle (5) is arranged on the holding rod (4), and holding rod (4) has endoporus (9) to be connected with connection tube (10), and connection tube (10) other end connects valve body (19); The electric contact vacuum meter (13) that is installed on the vacuum gauge stand (12) is arranged on the valve body (19), aerofluxus individual event valve (11) is arranged, the relief valve (15) that is installed on the pressure release valve seat (16) is arranged, display lamp (14) is installed on the vacuum meter (13), check valve (18) is arranged in the valve body (19), and valve body (19) other end connects negtive-pressure implement (17).
The arc of this utility model fetal head protection sucker (1), head dummy radian design for imitative baby, contact area with try one's best increase and fetal head, and the pulling force of fetal head unit's contact area is reduced, porous design in addition, more make suction in the equilibrium of scalp surface active force, injury-free with protection baby cranium brain; Its material can be selected the medical poisonless material soft, gentle, that mechanical strength is enough for use.
Suction nozzle of the present utility model (2), with after can conveniently unload, the sterilization that carries out disinfection, and can supporting large, medium and small serial number is to adapt to the needs of different baby's fetal heads.
This utility model provides the special-purpose medical apparatus and instruments of obstetrics of a kind of hospital for gynaecology and obstetrics attraction fetal head that practise midwifery is used, and is a kind of vacuum indication of having, and the negative pressure warning lamp that transfinites is arranged, and relief valve is arranged, and the novel vacuum extractor of fetal head protection sucker is arranged.Its fetal head gravitation can show on vacuum meter, can observe with vacuum meter easily and the supervision negative pressure condition, so that adjust negative pressure at any time; When negative pressure transfinited, the automatic bright enlightenment of display lamp was alert, transfinited to remind obstetrist's negative pressure, at this moment available relief valve quick pressure releasing; When the negative pressure deficiency, can in time use the negtive-pressure implement evacuation, in case gravitation is little, the suction nozzle slippage causes repeatedly to attract, and is unfavorable to puerpera and baby.After the fetus output, the quick venting negative pressure of available relief valve with the shortening stages of labor of racing against time, makes the apparatus practise midwifery reduce to minimum to mother and baby's side effect.Like this, this utility model can make fetal head gravitation be controlled in the scope of stable, safe, reliable, standard, to guarantee mother and baby's safety; This lays the foundation to industry standard and even the national standard of formulating vacuum extractor; Simultaneously, also the formulation of obstetrist's practise midwifery operating technology standard is laid the first stone.The fetal head protection sucker that this utility model is provided with, because the science design of its bionical how much radians and porous mechanics, increased contact area with fetal head, the pulling force of fetal head unit's contact area is reduced, the porous design makes suction in the equilibrium of scalp surface active force again, can protect fetus cranium brain not to be subjected to the damage of apparatus to greatest extent, prevent that suction nozzle is to the fetus cranium brain distortion of not growing incorrect how much extruding of intact fetal skull as yet and causing, damage, intracranial hemorrhage etc. and the generation of freezing; Safety, reliability and the success rate of obstetrics' practise midwifery vacuum extraction have been increased.Suction nozzle of the present utility model, with after can conveniently unload, the sterilization that carries out disinfection, and can supporting large, medium and small serial number is to adapt to the needs of different baby's fetal heads.Therefore, this utility model design science is reasonable, working specification, supercharging continuously, blood pressure lowering fast, and practise midwifery is safe and reliable; Both helped reducing the generation of malpractice, also made things convenient for practise midwifery doctor's standard operation, improved the scientific and technological content of practise midwifery apparatus, the medical technique level of maternity ﹠ child care center is promoted; Be applicable to that deliver a child in maternity ﹠ child care centers at different levels, practise midwifery is used.
