Biomechanism bathola izingane ngokuhlinzwa e izinhlobo ezahlukene previa

Biomechanism nokubeletha - lonke iqoqo ukunyakaza ezahlukene, okuyinto eyenza edabula lokuzalwa canal omama izithelo. Lezi izimo zihlobene ngokuqondile isakhiwo ukhalo zesifazane. Baqamba amanga kule flexion / isandiso lwekhanda komntwana, ijikeleziswa emhlabeni eksisi, le lateral Nokwehla fetus ikhanda kanye pendulum ukunyakaza okuhloswe ngaso intuthuko yalo kanye emgudwini wokuzala.

Zonke lezi ukunyakaza ebekelwa ubukhulu kanye ukuma ukhalo abesifazane, khona-amniotic fluid e eyanele ubuningi syrovidnoy amafutha, olwaluhlanganisa umzimba wengane, okuyinto kunciphisa ukuxabana kanye isayizi shape ikhanda lengane. Ngaphezu kwalokho, ukulethwa inikezwa biomechanism lesizalo umsebenzi, ngokunembile, Kufinyeta yayo. Lokhu kwakha ukunyakaza Translational ekunyusweni fetus kusukela komama lokuzalwa umsele. Okunye ukuthi ekunciphiseni kwesibeletho, kuyinto nemisipha yayo. Kulokhu, emisipheni round qinisa lesizalo phansi, phambi, futhi sacrouterine - bamba, ekuvimbeleni ehlangeni, futhi silungise khona ebusweni sacrum.

Biomechanism lokuzalwa ngasekhanda isethulo fetus (occipital) siqukethe izinto ezilandelayo: eguqa ikhanda futhi yehla kancane kancane phakathi komgodi okhalo. Lapho eguqa ikhanda kunqunywa iphuzu ehamba phambili - fontanelle Small, okuyinto eduze ukhalo olunezintambo umugqa. Kuyinto leli phuzu futhi kukhona lokuqala umqhewu zangasese. I kwesilevu umbungu ngesikhathi esifanayo uzibophezele esifubeni. Ekuqaleni ikhanda eshintsha ukumisa yayo. Ngaphezu kwalokho, lapho ezinyakazayo kusuka ezibanzi ukuze ingxenye emincane kwezitho zangasese yena enza Icebo lika. Ngalokho umuntu kuqondiswe kumuntu sacrum futhi ngemuva ekhanda kuya symphysis. Futhi ekugcineni kukhona ukwandiswa ikhanda uphinde uphume yayo kusukela indiza ka ukhalo - okuzelwe esiphongweni sakhe, ubuso kanye kwesilevu zokugcina. Emva kokuzalwa ekhanda uthatha isikhundla yayo yasekuqaleni. Ngaphezu kwalokho ozalwa emahlombe futhi iza uxoshwe ephelele-fetus.

Biomechanism okufukuzwa kulo breech isethulo sihlanganisa ukuhamba ukujikeleza futhi Translational, kodwa kulokhu-fetus sidlula ukhalo lokuzalwa canal phambili. Lapho lena eziyisisekelo Umhlahlandlela mezhvertilnaya gluteal umugqa. Kukhona amaphuzu alandelayo akha biomechanism izizukulwane: ezinqeni afakwa ukhalo bese ukuhambisa phezulu, emgogodleni fetus kwenza ukugoba lateral, ngemva kwalokho kufika esifubeni nesiphanga ibhande. Ukugoba ikhanda fetus sayo kwangaphakathi kwenzeka kakhulu kanyekanye. Inhloko okuzelwe esimweni insaliwe.

Biomechanism lokuzalwa Foot praevia siyafana nasemkhakheni breech. Ngokuvamile, ngemva ukudedelwa amniotic ukuvezwa uketshezi ngisho ngokwengxenye wesibeletho previa umlenze kungenziwa kwehlisa noma iwe sangasese. Lokhu inkimbinkimbi kakhulu futhi kubambezela inqubekela zomsebenzi. Uma wesibeletho is wembula ngokugcwele, nje ngemuva emlenzeni avele izibunu nokunye biomechanisms kuya izizukulwane ngenhla.

Njengoba singabona, biomechanism nokubeletha zemvelo incike ukuma okungukuthi isithelo, futhi kusukela iphuzu ukubeka wire.
