ʻO nā noi nui o ka Helium i ka lāʻau lapaʻau

He kinoea laha ole ka Helium me ke ano kemika He, he kinoea kala ole, ala ole, ono ole, hiki ole ke puhi ia, he mea make ole, me ka wela ko'iko'i o -272.8 degere Celsius a me ke kaumaha ko'iko'i o 229 kPa. I ka lāʻau lapaʻau, hiki ke hoʻohana ʻia ka helium i ka hana ʻana i nā lāʻau lāʻau lapaʻau kiʻekiʻe, nā laser helium-neon, nā pahi argon helium, a me nā mea lapaʻau ʻē aʻe, a me ka mālama ʻana i ka hānō, ka maʻi obstructive pulmonary maʻi a me nā maʻi ʻē aʻe. Eia kekahi, hiki ke hoʻohana ʻia ka helium no ke kiʻi ʻana i ka resonance magnetic, cryogenic freezing, a me ka hoʻāʻo ʻana i ke kinoea.

ʻO nā noi nui o ka helium i ka lāʻau lapaʻau penei:

1, MRI kiʻi: He haʻahaʻa loa ka Helium i ka heheʻe a me ka paila paila, a ʻo ia wale nō ka mea i paʻa ʻole i ke kaomi ʻana i ka lewa a me 0 K. Hiki i ka helium wai wai ke hiki i nā haʻahaʻa haʻahaʻa kokoke i ka ʻole loa (e pili ana i -273.15 ° C) ma hope o ka hana hou ʻana. ka hooluolu ana a me ke kaomi. Hoʻohana nui ʻia kēia ʻenehana wela ultra-haʻahaʻa i ka nānā ʻana i nā lāʻau lapaʻau. Ke hilinaʻi nei ke kiʻi resonance magnetic i ka helium wai e hoʻopili ana i nā magnet superconducting e hana i nā māla magnetic e hiki ke lawelawe i ke kanaka. Hiki i kekahi mau hana hou ke hoʻemi i ka hoʻohana ʻana i ka helium, akā pono mau ka helium no ka hana ʻana o nā mea kani MRI.

2.Helium-neon laser: Helium-neon laser he kukuiʻulaʻula monochromatic me ka'ōlinolino kiʻekiʻe, ke kuhikuhi maikaʻi a me ka ikaika nui. ʻO ka ʻōlelo maʻamau, ʻaʻohe hopena hoʻopōʻino o ka laser helium-neon haʻahaʻa i ke kino o ke kanaka, no laila ua hoʻohana nui ʻia i ka hana lapaʻau. ʻO nā mea hana o ka laser helium-neon he helium a me ka neon. I ka lāʻau lapaʻau, hoʻohana ʻia ka laser helium-neon haʻahaʻa haʻahaʻa e hoʻomālamalama i nā wahi ʻona, nā wahi ʻōhule, nā wahi ulcerated, nā ʻeha a pēlā aku. Loaʻa iā ia ka anti-inflammatory, anti-itching, ulu lauoho, hoʻoikaika i ka ulu ʻana o ka granulation a me ka epithelium, a hoʻolalelale i ka ho'ōla ʻana o nā ʻeha a me nā ʻeha. ʻOiai ma ke kahua o ka lāʻau lapaʻau aesthetics, ua hana ʻia ka laser helium-neon i "mea nani" maikaʻi. Helium-neon laser hana mea he helium a me neon, o ka helium ka auxiliary kinoea, neon ka nui hana kinoea.

3.Argon-helium pahi: argon helium pahi ua maʻa mau i loko o ka lapaʻau lapaʻau mea paahana, he argon helium anuanu kaʻenehana hoʻohana 'ia i loko o ka lāʻau lapaʻau o crystallization. I kēia manawa, nui nā halemai kūloko i ke kumu hoʻohālike hou loa o ke kikowaena cryotherapy pahi argon helium. ʻO ke kumukānāwai ʻo ka Joule-Thomson kumu, ʻo ia hoʻi ka hopena throttling kinoea. Ke hoʻokuʻu koke ʻia ke kinoea argon ma ka piko o ka nila, hiki ke maloʻo ka ʻiʻo maʻi i -120 ℃ ~ -165 ℃ i loko o ʻumi kekona. Ke hoʻokuʻu koke ʻia ka helium ma ka piko o ka nila, hana ia i ka hoʻomaʻamaʻa wikiwiki ʻana, e hoʻoheheʻe koke ai ka pōpō hau a hoʻopau i ka ʻōpū.

4, ʻO ka ʻike ʻana i ke kinoea: Helium leak detection e pili ana i ke kaʻina hana o ka hoʻohana ʻana i ka helium ma ke ʻano he tracer gas e ʻike ai i nā leaks i loko o nā pūʻolo like ʻole a i ʻole nā ​​​​pūnaewele hoʻopaʻa ʻana ma ke ana ʻana i kona neʻe ʻana i ka wā e pakele ai ma muli o ka leakage. ʻOiai ʻaʻole hoʻohana wale ʻia kēia ʻenehana i nā ʻoihana lāʻau lapaʻau a me nā ʻoihana lapaʻau, ua hoʻohana maikaʻi ʻia hoʻi i nā ʻano ʻē aʻe. I ka hiki ʻana mai i ka ʻike leak helium i ka ʻoihana lāʻau lapaʻau, hiki i nā hui hiki ke hāʻawi i nā hopena quantitative hilinaʻi a pololei e hoʻomaikaʻi i ka maikaʻi o kā lākou ʻōnaehana lawe lāʻau. Mālama ia i ke kālā a me ka manawa a hoʻomaikaʻi i ka palekana; i ka ʻoihana lāʻau lapaʻau, ʻo ka manaʻo nui i ka hoʻāʻo pono ʻana i ka pōʻai. ʻO ka hoʻāʻo ʻana o ka Helium leak e hōʻemi i ka hopena o ka hāʻule ʻana o ka huahana no nā mea maʻi a me nā limahana lapaʻau, a me ka pilikia o ke kuleana o ka huahana no nā mea hana.

6. Ka mālama ʻana i ka hānō: Mai ka makahiki 1990 mai, ua aʻo ʻia ka hui ʻana o ka helium-oxygen no ka mālama ʻana i ka hānō a me nā maʻi hanu. Ma hope mai, ua hōʻoia ka nui o nā haʻawina he maikaʻi nā hui helium-oxygen i ka hānō, COPD, a me ka maʻi puʻuwai puʻuwai. Hiki i nā huila helium-oxygen kiʻekiʻe ke hoʻopau i ka mumū o nā alaloa. ʻO ka inhalation o ka hui ʻana o ka helium-oxygen i kekahi kaomi hiki ke hoʻoheheʻe kino i ka mucous membrane o ka trachea a hoʻoikaika i ka kipaku ʻia o ka phlegm hohonu, e loaʻa ai ka hopena o ka anti-inflammation a me ka expectoration.
