I-Helium iyigesi engavamile enefomula yamakhemikhali Yena, igesi engenambala, engenaphunga, engenambitheki, engashi, engenabuthi, enezinga lokushisa elibucayi -272.8 degrees Celsius kanye nokucindezela okubalulekile kwe-229 kPa. Kwezokwelapha, i-helium ingasetshenziswa ekukhiqizeni imishayo yezinhlayiya zezokwelapha ezinamandla aphezulu, i-helium-neon lasers, imimese ye-argon helium, neminye imishini yezokwelapha, kanye nokwelapha isifuba somoya, isifo esingapheli se-pulmonary obstructive kanye nezinye izifo. Ngaphezu kwalokho, i-helium ingasetshenziselwa i-imaging magnetic resonance, i-cryogenic freezing, nokuhlola ukuqina kwegesi.
Izicelo eziyinhloko ze-helium emkhakheni wezokwelapha zihlanganisa:
I-1, imaging ye-MRI: I-Helium inephuzu elincibilikayo eliphansi kakhulu futhi elibilayo, futhi iyona kuphela into engaqini ekucindezelweni komkhathi kanye ne-0 K. I-helium ewuketshezi ingafinyelela emazingeni okushisa aphansi asondele ku-zero absolute (cishe -273.15 ° C) ngemva kokuphindaphindiwe ukupholisa kanye ne-pressurization. Lobu buchwepheshe bokushisa obuphansi kakhulu bubenza busetshenziswe kabanzi ekuskeneni kwezokwelapha. I-Magnetic resonance imaging incike ku-liquid helium encapsulating superconducting magnets ukuze kukhiqizwe amandla kazibuthe angasebenzela isintu. Ezinye izinto ezintsha zakamuva zinganciphisa ukusetshenziswa kwe-helium, kodwa i-helium isabalulekile ekusebenzeni kwezinsimbi ze-MRI.
I-2.I-laser ye-Helium-neon: I-laser ye-Helium-neon ukukhanya okubomvu kwe-monochromatic nokukhanya okuphezulu, isiqondiso esihle namandla agxilwe kakhulu. Ngokuvamile, i-laser ye-helium-neon enamandla aphansi ayinawo umthelela olimazayo emzimbeni womuntu, ngakho-ke isetshenziswa kabanzi emisebenzini yomtholampilo. Izinto ezisebenzayo ze-helium-neon laser yi-helium ne-neon. Ekwelashweni kwezokwelapha, i-laser ye-helium-neon yamandla aphansi isetshenziselwa ukukhipha izindawo zokuvuvukala, izindawo ze-bald, izindawo ezinezilonda, amanxeba njalonjalo. Ine-anti-inflammatory, anti-itching, ukukhula kwezinwele, ikhuthaza ukukhula kwe-granulation kanye ne-epithelium, futhi isheshisa ukuphulukiswa kwamanxeba nezilonda. Ngisho nasemkhakheni we-aesthetics yezokwelapha, i-helium-neon laser yenziwe "insimbi yobuhle" ephumelelayo. I-helium-neon laser yokusebenza impahla yi-helium neon, okuyi-helium eyigesi elisizayo, i-neon iyigesi esebenzayo eyinhloko.
3.Ummese we-Argon-helium: ummese we-argon helium uvame ukusetshenziswa kumathuluzi ezokwelapha emtholampilo, ubuchwepheshe bokuhlukaniswa obubandayo be-argon helium obusetshenziswa emkhakheni wezokwelapha we-crystallization. Njengamanje, izibhedlela eziningi zasekhaya zinemodeli yakamuva yesikhungo se-argon helium knife cryotherapy. Umgomo umgomo we-Joule-Thomson, okungukuthi umthelela wokudonsa igesi. Lapho igesi ye-argon ikhishwa ngokushesha esihlokweni senaliti, izicubu ezigulayo zingaqandiswa zibe -120℃~-165℃ phakathi kwemizuzwana eyishumi. Lapho i-helium ikhishwa ngokushesha esihlokweni senaliti, ikhiqiza ukufudumala ngokushesha, okubangela ukuba ibhola leqhwa lincibilike ngokushesha futhi liqede isimila.
4, Ukutholwa Kokuqina Kwegesi: Ukutholwa kokuvuza kwe-helium kubhekisela kunqubo yokusebenzisa i-helium njengegesi yokulandela umkhondo ukuze kutholwe ukuvuza kumaphakheji ahlukahlukene noma amasistimu okuvala ngokulinganisa ukugxila kwayo lapho ibaleka ngenxa yokuvuza. Nakuba lobu buchwepheshe bungasetshenziswa kuphela ezimbonini zemithi nemishini yezokwelapha, buphinde busetshenziswe kahle nakweminye imikhakha. Uma kuziwa ekutholweni kokuvuza kwe-helium embonini yezemithi, izinkampani ezinganikeza imiphumela enokwethenjelwa nenembile yobuningi zingathuthukisa ikhwalithi yezinhlelo zazo zokulethwa kwezidakamizwa. Konga imali nesikhathi futhi kuthuthukisa ukuphepha; embonini yemishini yezokwelapha, okugxilwe kakhulu ekuhlolweni kobuqotho bephakheji. Ukuhlolwa kokuvuza kwe-Helium kunciphisa ubungozi bokungaphumeleli komkhiqizo ezigulini nakubasebenzi bezokwelapha, kanye nobungozi besikweletu somkhiqizo kubakhiqizi.
6, Ukwelashwa kwesifuba somoya: Kusukela ngeminyaka yawo-1990, kube nocwaningo lwengxube ye-helium-oxygen yokwelapha isifuba somoya nezifo zokuphefumula. Kamuva, inani elikhulu lezifundo liye laqinisekisa ukuthi izingxube ze-helium-oksijeni zisebenza kahle ku-asthma, COPD, nesifo senhliziyo yamaphaphu. Izingxube ze-helium-oksijeni ezinomfutho ophezulu zingaqeda ukuvuvukala kwemigudu yomoya. Ukuhogela ingxube ye-helium-oksijeni ngengcindezi ethile kungasusa ngokomzimba ulwelwesi lwamafinyila kuqhoqhoqho futhi kukhuthaze ukuxoshwa kwe-phlegm ejulile, kufinyelele umphumela wokulwa nokuvuvukala kanye ne-expectoration.
