Amathangi e-nitrogen ewuketshezi, njengezitsha zokugcina izinto eziphilayo ezijulile, asetshenziswa kabanzi ezikhungweni zezokwelapha nasezindaweni zokuhlola. Ukuthuthukiswa kwezitsha ze-nitrogen ewuketshezi kube yinqubo eyenzeka kancane kancane, eyakhiwe yiminikelo yochwepheshe nezazi cishe iminyaka eyikhulu, ishintsha kusukela kuma-prototype okuqala kuya kobuchwepheshe obuhlakaniphile esibujwayele namuhla.
Ngo-1898, usosayensi waseBrithani uDuval wathola isimiso se-vacuum jacket adiabatic, esanikeza ukwesekwa okungokwemfundiso yokukhiqiza izitsha ze-nitrogen eziwuketshezi.
Ngo-1963, udokotela wezinzwa waseMelika uDkt. Cooper waqala ukwakha idivayisi yokubandisa esebenzisa i-nitrogen ewuketshezi njengomthombo wokubandisa. I-nitrogen ewuketshezi yaqondiswa ngesekethe evalwe nge-vacuum yaya esiqongweni sommese obandayo, igcina izinga lokushisa elingu--196°C, okwenza kube nokwelashwa okuphumelelayo kwezimo ezifana nesifo sikaParkinson kanye nezimila ngokuqandisa kwe-thalamus.
Ngo-1967, umhlaba wabona okokuqala ukusetshenziswa kwezitsha ze-nitrogen eziwuketshezi -196°C ukuze kulondolozwe umuntu ophilayo—uJames Bedford. Lokhu akugcini nje ngokubonisa intuthuko emangalisayo yesintu kwezesayensi yokuphila kodwa futhi kwamemezela ukusetshenziswa okusemthethweni kwesitoreji se-nitrogen esiwuketshezi kusetshenziswa izitsha ze-nitrogen eziwuketshezi, okugqamisa ukubaluleka kokusetshenziswa kwaso okwandayo kanye nenani laso.
Eminyakeni engamashumi amahlanu edlule, isitsha se-nitrogen esiwuketshezi siphumelele kakhulu emkhakheni wezesayensi yokuphila. Namuhla, sisebenzisa ubuchwepheshe bokugcina amaseli e-nitrogen ewuketshezi ku--196℃, okubangela ukulala kwesikhashana ngenkathi kulondolozwa izici zawo ezibalulekile. Ekunakekelweni kwezempilo, isitsha se-nitrogen esiwuketshezi sisetshenziselwa ukugcina amaseli egazi, isikhumba, igazi, amaseli, umnkantsha, kanye nezinye izibonelo zezinto eziphilayo, okufaka isandla ekuthuthukisweni kwemithi yokwelapha i-cryogenic. Ngaphezu kwalokho, kuvumela umsebenzi owandisiwe wemithi ye-biopharmaceuticals njengemigomo kanye nama-bacteriophages, okwenza kube lula ukuhunyushwa kwemiphumela yocwaningo lwesayensi.
Isitsha se-nitrogen esiwuketshezi se-Haier Biomedical sihlangabezana nezidingo ezahlukahlukene zabasebenzisi njengezikhungo zocwaningo lwesayensi, i-elekthronikhi, amakhemikhali, izinkampani zemithi, amalabhorethri, izibhedlela, iziteshi zegazi, kanye nezikhungo zokulawula izifo. Siyisisombululo esihle sokugcina igazi le-umbilical cord, amangqamuzana ezicubu, kanye namanye amasampula ebhayoloji, ukuqinisekisa umsebenzi ozinzile wesampula yamaseli endaweni ephansi yokushisa.
Ngokuzibophezela emsebenzini wenkampani "wokwenza impilo ibe ngcono," i-Haier Biomedical iyaqhubeka nokuthuthukisa izinto ezintsha ngobuchwepheshe futhi ifuna ushintsho olukhulu ekuphishekeleni ubuhle ngokuvikelwa okuhlakaniphile kwesayensi yokuphila.
1. Umklamo omusha ongenaqhwa
Isitsha se-nitrogen esiwuketshezi se-Haier biomedical sinesakhiwo esiyingqayizivele sokukhipha umoya esivimbela ngempumelelo ukwakheka kweqhwa entanyeni yesitsha, kanye nesakhiwo sokukhipha amanzi esisha sokuvimbela ukunqwabelana kwamanzi phansi ngaphakathi endlini.
2. Uhlelo lokubuyisela amanzi emzimbeni oluzenzakalelayo
Isitsha sihlanganisa kokubili ukugcwalisa kabusha ngesandla kanye nokuzenzakalelayo, sifaka umsebenzi wokudlula igesi eshisayo ukuze kuncishiswe ngempumelelo ukuguquguquka kwezinga lokushisa ethangini ngesikhathi sokugcwalisa kabusha uketshezi, ngaleyo ndlela kuthuthukiswe ukuphepha kwamasampula agciniwe.
3. Ukuqapha kanye nokuqapha ukusebenza ngesikhathi sangempela
Isitsha sihlonyiswe ngokuqapha izinga lokushisa kanye noketshezi ngesikhathi sangempela okuhlanganisa imodyuli ye-IoT yokudlulisa idatha ekude kanye nama-alamu, okuthuthukisa ukuphepha, ukunemba, kanye nokulula kokuphathwa kwamasampula, okwandisa inani lamasampula agciniwe.
Njengoba ubuchwepheshe bezokwelapha buthuthuka, ukuhlola okujulile kobuchwepheshe be-cryogenic obungu-196℃ kunezithembiso namathuba empilweni yabantu. Igxile ezidingweni zomsebenzisi, i-Haier Biomedical isazinikele emisha, futhi yethule isisombululo esiphelele sokugcina isitsha se-nitrogen esiwuketshezi kuzo zonke izimo kanye nezingxenye zomthamo, okuqinisekisa ukuthi inani lamasampula agciniwe liyakhuliswa futhi liqhubeka nokufaka isandla emkhakheni wesayensi yokuphila.
