Amathangi e-nitrogen ewuketshezi, njengeziqukathi zokugcina izinto eziphilayo ze-cryogenic, asetshenziswa kakhulu ezikhungweni zezokwelapha nasezilungiselelweni zokuhlola.Ukuthuthukiswa kweziqukathi ze-nitrogen eziwuketshezi kube inqubo ehamba kancane, elolongwa iminikelo yochwepheshe nezazi esikhathini esicishe sibe yikhulu, kusukela kuzibonelo zokuqala kuya kubuchwepheshe obuhlakaniphile esibujwayele namuhla.
Ngo-1898, usosayensi waseBrithani u-Duval wathola isimiso se-vacuum jacket i-adiabatic, eyanikeza ukusekelwa kwethiyori ekukhiqizeni iziqukathi ze-nitrogen eziwuketshezi.
Ngo-1963, udokotela ohlinzayo wezinzwa waseMelika uDkt. Cooper waqala ukwenza umshini wokuqandisa esebenzisa initrogen ewuketshezi njengomthombo wesiqandisi.I-nitrogen ewuketshezi yayiqondiswe ngesekhethi evalwe nge-vacuum iye esihlokweni sommese obandayo, igcina izinga lokushisa elingu--196°C, ivumela ukwelashwa okuphumelelayo kwezimo ezifana nesifo sika-Parkinson kanye nezimila ngokubanda kwethalamus.
Ngo-1967, umhlaba wabona isenzakalo sokuqala sokusebenzisa iziqukathi ze-nitrogen eziwuketshezi ezingu-196°C ukuze kugcinwe umuntu ojulile we-cryogenic—James Bedford.Lokhu akuzange nje kufanekisele inqubekelaphambili ephawulekayo yesintu kusayensi yezempilo kodwa futhi kwamemezela ukusetshenziswa okusemthethweni kwendawo yokugcina i-cryogenic ejulile kusetshenziswa iziqukathi ze-nitrogen eziwuketshezi, okugqamisa ukubaluleka kokusetshenziswa kwayo okwandayo kanye nenani.
Engxenyeni yekhulu edlule, isiqukathi se-nitrogen esiwuketshezi senze umkhakha wesayensi yezempilo.Namuhla, isebenzisa ubuchwepheshe be-cryopreservation ukuze ilondoloze amaseli ku-nitrogen ewuketshezi ku--196 ℃, idala ukulala kwesikhashana kuyilapho ilondoloza izici zayo ezibalulekile.Ekunakekelweni kwezempilo, isitsha se-nitrogen esiwuketshezi sisetshenziselwa ukugcinwa kwezitho, isikhumba, igazi, amaseli, umnkantsha wamathambo, namanye amasampula ebhayoloji, okunomthelela ekwakhiweni komuthi we-cryogenic womtholampilo.Ukwengeza, ivumela umsebenzi owandisiwe wemithi ye-biopharmaceuticals njengemithi yokugoma kanye ne-bacteriophages, yenza kube lula ukuhunyushwa kwemiphumela yocwaningo lwesayensi.
Isiqukathi se-nitrogen esiwuketshezi se-Haier Biomedical sihlangabezana nezidingo ezihlukahlukene zabasebenzisi njengezikhungo zocwaningo lwesayensi, ogesi, amakhemikhali, izinkampani zemithi, amalabhorethri, izibhedlela, iziteshi zegazi, nezikhungo zokulawula izifo.Kuyisixazululo esifanelekile sokulondoloza sokugcina igazi lenkaba, amaseli ezicubu, namanye amasampula ebhayoloji, okuqinisekisa umsebenzi wesampula wamaseli ozinzile endaweni enezinga lokushisa eliphansi.
Ngokuzibophezela emkhankasweni wezinkampani “wokwenza ukuphila kube ngcono,” i-Haier Biomedical iyaqhubeka nokuqhuba izinto ezintsha ngobuchwepheshe futhi ifuna uguquko olukhulu ekuphishekeleni ukwenza kahle ngokuvikela okukhaliphile kwesayensi yempilo.
1. Idizayini engenasithwathwa
Isiqukathi se-nitrogen esiwuketshezi se-Haier biomedical sinesakhiwo esiyingqayizivele sokukhipha umoya esivimbela ngempumelelo ukwakheka kwesithwathwa entanyeni yesiqukathi, kanye nesakhiwo esisha sokudonsa amanzi ukuze kuvinjelwe ukunqwabelana kwamanzi phansi endlini.
2. Uhlelo oluzenzakalelayo lokubuyisela amanzi emanzini
Isiqukathi sihlanganisa kokubili ukugcwalisa okwenziwa ngesandla nokuzenzakalelayo, okuhlanganisa umsebenzi wokudlula igesi eshisayo ukuze kuncishiswe ngempumelelo ukuguquguquka kwezinga lokushisa ethangini ngesikhathi sokugcwalisa uketshezi, ngaleyo ndlela kuthuthukiswe ukuphepha kwamasampula agciniwe.
3.Ukuqapha kwesikhathi sangempela kanye nokuqapha ukusebenza
Isiqukathi sifakwe izinga lokushisa lesikhathi sangempela nokuqapha izinga loketshezi okuhlanganisa imojula ye-IoT yokudlulisa idatha okukude nama-alamu, okuthuthukisa ukuphepha, ukunemba, kanye nokuphathwa kalula kwesampula, okukhulisa inani lamasampuli agciniwe.
Njengoba ubuchwepheshe bezokwelapha buthuthuka, ukuhlola okujulile kobuchwepheshe be-cryogenic -196℃ kunezithembiso namathuba empilo yabantu.Igxile ezidingweni zabasebenzisi, i-Haier Biomedical isalokhu izinikele ekusungulweni okusha, futhi yethule isisombululo esiphelele sokugcina isiqukathi se-nitrogen esiwuketshezi sazo zonke izimo nezingxenye zevolumu, iqinisekisa ukuthi inani lamasampula agciniwe liyakhuliswa futhi linikela ngokuqhubekayo emkhakheni wesayensi yezempilo. .
