Ultrasound Kwa Nkhumba

Masiku ano kunyamula makina ultrasound mimba nkhumba ndi otsika mtengo, cholimba, zambiri kunyamula.Komabe, si makina onse a nkhumba a ultrasound omwe ali ndi lingaliro lomwelo powonetsa tinthu tating'onoting'ono.Izi zimatengera mawonekedwe a makina a ultrasound a nkhumba.

Makina osavuta a A-mode ultrasound adagwiritsidwa ntchito kuti azindikire mimba ya nkhumba pogwiritsa ntchito ultrasound.Zida za ultrasound za nthawi yeniyeni ya B zidasinthidwa pamene teknoloji idasinthidwa kuti iwonetsetse ntchito yoberekera ya nkhumba, kuphatikizapo kuzindikira mimba ndi kuwunika momwe akubala.Masiku ano makina opangira ma ultrasound ndi otsika mtengo, olimba, osavuta kunyamula kuposa zida zamankhwala zofananira.Komabe, si makina onse a nkhumba a ultrasound omwe ali ndi lingaliro lomwelo powonetsa tinthu tating'onoting'ono.Izi zimatengera ma transducer ndi mawonekedwe a makina a nkhumba a ultrasound.

Ultrasound Kwa Nkhumba
Mfundo ya ultrasound ndiyoti magetsi akagwiritsidwa ntchito, mitundu ina ya kristalo yomwe ili mkati mwa transducers (kapena probes) imanjenjemera ndikupanga mafunde akupanga.Mafunde akupanga akupanga amatha kutumizidwa ndikulandiridwa ndi makhiristo omwewo.Kufufuza kwa 3.5 megahertz (MHz) kumakhala ndi makristasi akuluakulu.Ngakhale chinyamacho chimalowa kwambiri ndi mafunde otsika omwe akupanga mafunde opangidwa ndi kafukufukuyu, chigamulocho nthawi zambiri chimakhala chosauka (kutha kuzindikira mapangidwe).Mosiyana ndi izi, mafunde apamwamba akupanga mafunde opangidwa ndi ma transducer a 5.0 ndi 7.5 MHz amayenda mtunda waufupi, zomwe zimatsogolera ku kusamvana kwakukulu.

Kupezeka kwa ma transducers osiyanasiyanawa kumatanthauza kuti chigamulo chikhoza kupangidwa pakati pa kujambula kosaya ndi chithunzithunzi chabwinoko kapena kujambula mozama ndi chithunzi chochepa.Makonzedwe a kristalo a transducer amalola kusintha kowonjezera kuti musinthe gawo lazithunzi lomwe likuwoneka.Ma convex kapena ma probe a gawo amapereka chithunzi chofanana ndi chitumbuwa cha chitumbuwa ndipo chimakhala chocheperako pafupi ndi chosinthira ndipo pang'onopang'ono chimakula patali kwambiri kuchokera komwe kumachokera.Zofufuza zam'mbali zimapanga chithunzi cha makona anayi, chamitundu iwiri.Pamene chiwalo chokhudzidwacho chili mkati mwa thupi ndipo malo ake enieni sakudziwika, kuyang'ana kwakukulu kumathandiza.

Makina Onyamula a Ultrasound a Mimba ya Nkhumba
Makina onyamula ma ultrasound a pathupi la nkhumba akhala akugwiritsidwa ntchito mobwerezabwereza kuona vesicle ya embryonic (embryonic fluid m'chiberekero) ikuyamba pakapita sabata lachitatu koma sabata yachisanu isanakwane isanakwane poyang'ana mimba yoyambirira mu nkhumba.

Kafufuzidwe ka 3.5 MHz kakale kakayikidwa kunja pamimba ya mkazi popanga.Kafukufuku wa 5.0 MHz wakhala akugwiritsidwa ntchito mocheperapo pazamalonda chifukwa chakuya kwake pang'ono, ngakhale kuti ndizovuta komanso zolondola.Pamene RTU ikugwiritsidwa ntchito> 24 kwa masiku 28 pambuyo pa kukweretsa, makina onyamula ma ultrasound a mimba ya nkhumba atsimikizira kukhala opambana komanso odalirika.Mosiyana ndi kufufuza m'magawo otsiriza a mimba, kukhudzidwa ndi kulondola kumawoneka kuti kumachepa kwambiri pamene njirayi ikuchitika tsiku la 24 lisanafike. Kuzindikiritsa posachedwa kumapambana zida zamtundu wa A-mode zotsika mtengo.Transducer nthawi zambiri imayikidwa pamimba pamunsi, kutsogolo kwa mwendo wakumbuyo, kuti igwiritsidwe ntchito kunja.Ndi transducer ya 3.5 MHz yokha yomwe imatha kulowa mokwanira kuti njirayi ikhale yothandiza popeza chiberekero choyambilira chimakhala pafupi ndi chiuno.

Ma ultrasound oyambirira a nkhumba angaperekenso zambiri zothandiza.Mwachitsanzo, ngati akazi apezeka kuti alibe pakati pakati pa masiku 18 ndi 21 pambuyo pa kukwatiwa, akhoza kufufuzidwa mozama za estrus, kuberekedwa atangobereka, kapena kuphedwa ngati sangathe kusonyeza estrus.Kuzindikira kwa nthawi yeniyeni kuti ali ndi pakati kungathandizenso ofufuza kumvetsetsa chifukwa chake nyama zomwe zimapezeka kuti zili ndi pakati pakati pa masiku 21 ndi 25 zimalephera kusunga mimba ndi kupita ku estrus mobwerezabwereza.

Eaceni ndi makina opanga makina a ultrasound.Tili odzipereka ku luso lamakono la ultrasound ndi kujambula kwachipatala.Motsogozedwa ndi luso komanso molimbikitsidwa ndi zomwe makasitomala amafuna komanso kukhulupirirana, EACEni tsopano ili m'njira yoti ikhale yopikisana pazachipatala, ndikupangitsa kuti chithandizo chamankhwala chipezeke padziko lonse lapansi.
