Description

The multifunction manual membrane-repturing device

Technical field

This utility model relates to a kind of auxiliary implement of practicing midwifery, and especially a kind of multifunction manual membrane-repturing device is applicable to that active phase uterine inertia or active phase uterine contraction mobilize the puerpera of difficulty.

Background technology

In department of obstetrics and gynecology are clinical, often run into the puerpera that active phase uterine inertia or active phase uterine contraction start difficulty, this situation often causes that stages of labor is long, causes puerpera's fatigue, uterine contraction is more weak, even develops complications and postpartum hemorrhage etc.In such cases, the effective ways of processing are to adopt sharp weapon such as injection needle or mosquito forceps to carry out artificial rupture of membrane, by puncturing amniotic membrane, strengthen to stimulate uterine contraction, effectively promote the progress of stages of labor, alleviate puerpera's misery.But utilize sharp weapon ruptures of membranes such as injection needle or mosquito forceps to have following shortcoming: 1, use is dangerous, stabs puerpera's vagina easily, also injures medical personnel's hands easily to refer to; 2, it is wayward that thorn reaches the cut size deeply, and the mistake of thorn deeply easily injures fetal head; 3, because of the rupture of membranes afterwaters flows out for flowing out through vagina naturally, the too fast fetal cord that causes of its flow velocity prolapses, and makes fetal distress, even dies from the palace; When amniotic fluid is flowed through cervix uteri and injury of birth canal face, can cause amniotic embolism, and easily produce cross infection; 4, when special circumstances such as vasa previa, because of the rupture of membranes point is to carry out under finger touch, thorn point is selected in the blood vessel place sometimes, causes hemorrhagely, can jeopardize fetus life.

Summary of the invention

The purpose of this utility model be to provide a kind of can not only rupture of membranes, and safe in utilization, its rupture of membranes point can be selected under situation about monitoring, amniotic fluid can not form thromboembolism and avoid a kind of multifunction manual membrane-repturing device of cross infection in intravaginal.

For reaching above purpose, the technical scheme that this utility model adopted is: this multifunction manual membrane-repturing device, constitute by negative pressure cylindrical shell, exhaust tube, end at negative pressure cylindrical shell contact amniotic fluid film is established the bell mouth of covering arcuation, cover is loaded onto transparent elastic film on the lural mouth of covering arcuation, fibre-optic bundle on the lural inboard bonding of covering arcuation, establish cone-shaped funnel in the outer end of negative pressure cylindrical shell, thin layer of glass plate in the oral area shutoff of cone-shaped funnel is established flexible rotating blade in inboard, negative pressure cylindrical shell middle part.This utility model is also implemented by following measure: the inner end of described fibre-optic bundle is bonded in the both sides of covering arcuation bell mouth inwall, and be symmetrical arranged, the outer end contacts with electroluminescent lamp, accumulator is fixedly established in the oral area outside at cone-shaped funnel, make electroluminescent lamp bright by accumulator, by fibre-optic bundle light source is reached in the bell mouth of covering arcuation again, because the reflection action of covering arcuation bell mouth inwall, make light focus on the center, thereby illuminate the position that picks up amniotic membrane; Described flexible rotating blade is a triangular, be vertically fixed on the end of knife bar, and point of a knife points to axis, knife bar is fixed with plastic hoop, stretching, rotating blade is symmetric establishes two, plastic hoop is attached on the inwall of negative pressure cylindrical shell and is provided with, and the fixing magnetic piece of going up in the outer end of knife bar is established the promotion magnetic piece that the magnetic piece with the knife bar end attracts each other in the outside of negative pressure cylinder body wall; The axis angle of the axis of described cone-shaped funnel and negative pressure cylindrical shell is the 90-135 degree, is provided with illuminator in inside, junction, so that observation is used; The bell mouth of described covering arcuation is that transparent plastic is made, the lural bore of its covering arcuation is 20-40mm, the lural degree of depth of covering shape is 10-12mm, and the length of its negative pressure cylindrical shell is 80-100mm, and the mouth diameters of its cone-shaped funnel is consistent with the lural bore of covering arcuation.When using this utility model, hand-held negative pressure cylindrical shell, the bell mouth of covering arcuation is inserted in the cervix uteri mouth from vagina, make transparent elastic film touch amniotic sac, adopt syringe cylinder to insert exhaust tube then, bleed, making in the negative pressure cylindrical shell becomes negative pressure state, at this moment, amniotic membrane sucks in the bell mouth of covering arcuation in company with transparent elastic film, and opening power makes optical fibers luminous, the situation that medical personnel can be inhaled into from outer end thin layer of glass plate observation amniotic membrane, when determining that sucking the position does not have blood vessel, will promote magnetic piece again and inwardly advance, drive the magnetic piece of knife bar end, knife bar is pushed ahead, make flexible rotating blade contact amniotic membrane, at this moment, rotation promotes magnetic piece again, flexible rotating blade rotates, thereby cuts amniotic membrane; After cutting amniotic membrane, amniotic fluid enters in the negative pressure cylindrical shell, can extract the control amniotic fluid discharge and the rate of outflow by syringe cylinder.

The beneficial effects of the utility model are: 1, the amniotic fluid film is cut after adopting pad pasting to pick up again, and is safe in utilization, reliable; 2, the whole operation process is carried out under totally-enclosed, can effectively avoid cross infection; 3, amniotic fluid flows out and carries out under negative pressure state, and flow and flow velocity are controlled easily; 4, the thorn film carries out under visual, and choice of location is accurate, can effectively avoid hemorrhage.
