I-Ultrasound Yezingulube

Umshini wanamuhla we-ultrasound ophathwayo wokukhulelwa kwezingulube awubizi kakhulu, uqinile, uyaphatheka.Kodwa-ke, akuwona wonke umshini we-swine ultrasound onesinqumo esifanayo sokubonisa izakhiwo ezincane.Lokhu kuncike ekubonisweni komshini we-ultrasound wezingulube.

Imishini ye-ultrasound ye-A-mode elula yasetshenziswa ukuxilonga ukukhulelwa kwezingulube kusetshenziswa i-ultrasonography.Imishini ye-ultrasound yemodi yesikhathi sangempela ye-B yashintshwa njengoba ubuchwepheshe buthuthukisiwe ukuze kuhlolwe umsebenzi wokuzala wezingulube, okuhlanganisa ukutholwa kokukhulelwa nokuhlola isimo sokuzala.Imishini yanamuhla ye-ultrasound ayibizi kangako, iqinile, iyaphatheka kunemishini yezokwelapha eqhathaniswayo.Kodwa-ke, akuwona wonke umshini we-swine ultrasound onesinqumo esifanayo sokubonisa izakhiwo ezincane.Lokhu kuncike kumjikelezo we-transducer kanye nesekhethi yomshini we-swine ultrasound.

I-Ultrasound Yezingulube
Isimiso se-ultrasound siwukuthi lapho kusetshenziswa amandla kagesi, izinhlobo ezithile zekristalu ezingaphakathi kwama-transducers (noma ama-probes) ziyandindizela futhi zidale amagagasi e-ultrasonic.Amagagasi e-ultrasonic abonisiwe angathunyelwa futhi amukelwe amakristalu afanayo.I-3.5 megahertz (MHz) probe iqukethe amakristalu amakhulu.Nakuba isilwane singene ngokujulile ngamaza aphansi e-ultrasonic akhiqizwa yile probe, isixazululo ngokuvamile sibi (ikhono lokubona izakhiwo).Ngokuphambene, amagagasi aphakeme kakhulu e-ultrasonic akhiqizwa ama-transducer angu-5.0 kanye no-7.5 MHz ahamba amabanga amafushane, okuholela ekulungisweni kwesithombe okukhulu kakhulu.

Ukutholakala kwalawa ma-transducer ahlukahlukene kusho ukuthi isinqumo singenziwa phakathi kwesithombe esingajulile esinokulungiswa okungcono kwesithombe noma ukujula kwesithombe okunokucaca okuphansi kwesithombe.Ukuhlelwa kwekristalu ye-transducer kuvumela ukwenza ngokwezifiso okwengeziwe ukuze uguqule inkambu yesithombe esibonakalayo.Ama-convex noma ama-sector probe ahlinzeka ngesithombe esifana nocezu lukaphaya futhi sincane kakhulu eduze kwe-transducer futhi siya ngokuya siba banzi ebangeni elikhulu ukusuka emthonjeni.Ama-linear probe akhiqiza isithombe esingunxande, esinezinhlangothi ezimbili.Uma isitho esithakaselwayo sijule ngaphakathi emzimbeni futhi indawo ekuso ingaqiniseki, ukubuka okubanzi kuyasiza.

Umshini Ophathwayo We-Ultrasound Wokukhulelwa Kwengulube
Umshini ophathwayo we-ultrasound wokukhulelwa kwezingulube uvame ukusetshenziswa ukubona i-embryonic vesicle (uketshezi lwe-embryonic esibelethweni) oluqala esikhathini esithile ngemva kwesonto lesithathu kodwa ngaphambi kwesonto lesihlanu ngemva kokuzala ngenkathi kuhlolwa ukukhulelwa kusencane engulube.

I-3.5 MHz probe ngokomlando ibekwe ngaphandle esiswini sowesifazane kuzilungiselelo zokukhiqiza.I-5.0 MHz probe isetshenziswe kancane kakhulu kuzilungiselelo zezentengiso ngenxa yokushona kwayo okuncane, nakuba ibucayi kakhulu futhi inembe.Uma i-RTU isetshenziswa>ezinsukwini ezingama-24 kuya kwezingu-28 ngemva kokukhwelana, umshini ophathwayo we-ultrasound wokukhulelwa kwezingulube ubonakale uyimpumelelo futhi uthembekile.Ngokuphambene nokuhlolwa ezigabeni zakamuva zokukhulelwa, kokubili ukuzwela nokunemba kubonakala kuncipha kakhulu uma le ndlela yenziwa ngaphambi kosuku lwama-24. Ngenxa yomthamo wokubona i-embryonic vesicle ngenkathi wenza i-RTU yangaphandle ngemva kwe-d 24, ukunemba kokukhulelwa. ukuhlonza ngokushesha kushaya imishini yemodi ye-A engabizi kakhulu.I-transducer ivame ukufakwa ngaphansi kwesisu, ngqo phambi komlenze wangemuva, ukuze kusetshenziswe ngaphandle.I-transducer engu-3.5 MHz kuphela engangena ngokujwayelekile ukuze le nqubo ibe wusizo njengoba isibeletho esisanda kukhulelwa siseduze ne-pelvis.

I-ultrasound yokuqala yezingulube nayo inganikeza ulwazi oluwusizo.Isibonelo, uma abesifazane kutholakala ukuthi abakhulelwe phakathi kwezinsuku eziyi-18 nezingama-21 ngemva kokukhwelana, bangahlolelwa i-estrus, bazalwe ngokushesha nje lapho sebevundile, noma babulawe uma bengakwazi ukubonisa i-estrus.Ukutholwa kwesithombe esisheshayo sesikhathi sangempela sokukhulelwa kungase futhi kusize abacwaningi baqonde ukuthi kungani izilwane ezitholakala zikhulelwe phakathi kwezinsuku ezingama-21 nezingama-25 zehluleka ukugcina ukukhulelwa kwazo futhi ziphindele ku-estrus.

I-Eaceni ingumkhiqizi wemishini ye-ultrasound ephathwa ngesandla.Sizibophezele ekwenziweni okusha kwe-ultrasound yokuxilonga kanye nesithombe sezokwelapha.Iqhutshwa ukusungula izinto ezintsha futhi igqugquzelwa ukufunwa kwamakhasimende nokwethenjwa, i-Eceni manje isendleleni yokuba inkampani eqhudelanayo kwezokunakekelwa kwezempilo, okwenza ukunakekelwa kwezempilo kufinyeleleke emhlabeni jikelele.
