Zvakachengeteka kushandisa ultrasound here?
Vanachiremba havasi kupa mhinduro isina kufanira. Sezvaunoziva, zvinhu zvose zvinonyangadza uye zvinhu zvose mishonga - inongova chirwere chete. Vanaamai vazhinji vanotitaurira kuti mushure mekudzivirira kwechidiki mwana anotanga kusongana, kuzvibata zvakanyanya, sekunge kuratidza kusagutsikana. Pane imwe nguva zvaive zvakasikisa kutaura kuti ultrasound inonzi inoputsa DNA uye inotungamirira kuchinjwa pakuumbwa kwema fetus tishues. Zvisinei, sayenzi inonyatsoramba ichi. Panguva ino, kukanganisa kwe ultrasound kune amai ne fetus hazvina kubvumidzwa zvakajeka. Asi kurambwa kwe ultrasound kunogona kutungamirira pamigumisiro yakakomba inobatanidza nekukurumidza kuonekwa kwezvirwere zvakasiyana-siyana zve fetus. Amai, ivai vanonzwisisa, kana pane uchapupu hwekutsvakurudza, apo ruzivo rwakajeka runopfuura hukusava nekukuvadza, usatya. Vimba nechiremba, kwete "nyaya dzinotyisa" iyo shamwari dzinoti. Uye kunyange zvazvo zvigadzirwa zvemazuva ano zvichibvumira kubatanidzwa kwebasa romumwoyo inonzi embryo kubva kumavhiki mana kubvira pakuberekwa, uye motokari yekuita kubva mavhiki masere, chidzidzo chekutanga hachina kukurudzirwa kuti chiitwe mberi kwemavhiki gumi ekuzvitakura. Pane imwe purogiramu, maererano neiyo vanaamai vari mberi vachaendeswa kune ultrasound.
Mushonga we ultrasound unoshanda sei? Inounza mazaya ane mhepo yepamusoro-pfupi iyo inaudible nenzeve yevanhu (3.5-5MHz). Iyi mhepo haisi yemhepo ine simba, inofananidzwa nemutinhiro weruzhinji unobudiswa nema dolphins (haisi ngozi iyo iyi mhuka inomirira ultrasound mumishonga). Mvura, mazai e-ultrasonic anobatsira ma dolphin kuziva chiyero uye nzvimbo yechinhu. Uyewo, chiratidzo che ultrasound chinobvumira vanachiremba kuti vaenzanise ukuru uye chinzvimbo che fetus. I-wave-yeU.S., inoratidzirwa kubva kumatumbu emuviri, inotumira chiratidzo chekupindura, icho chinoshandurwa kuva mufananidzo pane chekuona.
Kutanga ultrasound
Mavhiki 10-12 - kutsunga nguva chaiyo yekuberekwa, kuongororwa kwekubata pamuviri, kusarudzwa kwenhamba yemashira uye chimiro cheparcenta maitiro. Ikozvino, kuberekwa kusina kukura, kutyisa kwekuparara kwepamuviri, ectopic pamuviri uye zvimwe zvinokanganisa zvinogona kuonekwa.
Yechipiri ultrasound, vhiki 20-24
Kutsunga kwehuwandu uye hutano hweamniotic fluid, chiyero chekusimbiswa kweparcenta, kuongororwa kwemuviri wechechecheche, kuratidza kwekukura kwemaitiro (kuongororwa kwepenital malformations yenheyo yenheyo, kunyanya hydrocephalus). Panguva ino, iwe unogona kusarudza hutano hwemwana asati aberekwa.
Chechitatu ultrasound, vhiki 32-34
Kutaurirana kwe fetus size kusvika panguva yekuzvitakura, nzvimbo yemucheche muchibereko, kuongororwa kweropa ruchibuda mu-placenta, kuongororwa kwehutachiona uye zvimwe zvinhu zvinokosha zvaunoda kuziva nezvekutumira izvo zvichatanga nokukurumidza. Ultrasound kuongororwa mune mamwe mazwi ekudzivirira, sekutonga, inoitwa maererano nemirairo yechiremba (nokuda kwezviratidzo zvakananga kana kuti kujekesa dhesi).
Tatu-dimensional ultrasound - 3D
Iko dzimwe nguva kunonzi inonzi 4-dimensional ultrasound (yechina denga ndiyo nguva). Mufananidzo wekutsvaga mukati mekutsvakurudza uku kunobvumira kuti zviri nani kuongorore zvimwe zvivako izvo zvakaoma kuwanika nekutsvakurudza mune maviri-dimensional (yakasikwa) maitiro. Iyi ruzivo inonyanya kukosha pakusarudza kunze kwekuvandudzwa kwemasalies. Uye, chokwadi, kutsvakurudza uku kunonyanya kufadza kune vabereki pachavo. Kana iyo inowanzoitwa maviri-dimensional ultrasound kuongororwa kwecheche yakanyanya kuoma - pfungwa dzisinganzwisisiki nemitsara haisi kupa mufananidzo wakazara. Nechifananidzo chetatu-dimensional, unogona kuona mwana sezvaari chaizvoizvo. Zvisinei, inofanira kuyeukwa kuti pamusana pekufananidza mifananidzo chiremba anosimbisa simba rechiratidzo, saka usashandise iyi nzira. Mufananidzo mutsvuku mumimba ichava yekutanga mumufananidzo wake album. Uye iye achatuma nhume dzake dzokutanga kuvabereki vake-achakuzunguzira ne peneni. Iye zvino tava kuziva kana zvinokuvadza kuita ultrasound pakuberekwa.
