Helium gas ne da ba kasafai ba tare da tsarin sinadarai Shi, marar launi, mara wari, iskar gas mara daɗi, mara ƙonewa, mara guba, tare da matsanancin zafin jiki na -272.8 digiri Celsius da matsa lamba na 229 kPa. A cikin likitanci, ana iya amfani da helium wajen samar da katako mai ƙarfi na likitanci, laser helium-neon, wuƙaƙen helium na argon, da sauran kayan aikin likita, da kuma maganin cutar asma, cututtukan huhu na huhu da sauran cututtuka. Bugu da ƙari, ana iya amfani da helium don hoton maganadisu na maganadisu, daskarewa na cryogenic, da gwajin hana gas.
Babban aikace-aikacen helium a fannin likitanci sun haɗa da:
1, MRI Hoton: Helium yana da ƙananan narkewa da tafasa, kuma shine kawai abu wanda baya ƙarfafawa a matsa lamba na yanayi kuma 0 K. Liquefied helium zai iya kaiwa ƙananan yanayin zafi kusa da cikakken sifili (kimanin -273.15 ° C) bayan maimaitawa. sanyaya da kuma matsa lamba. Wannan fasaha mai ƙarancin zafin jiki ta sanya ta yin amfani da ita sosai a cikin binciken likita. Hoto na maganadisu na maganadisu ya dogara ne akan helium ruwa mai ɗaukar hoto mai ɗaukar hoto don samar da filayen maganadisu waɗanda zasu iya yiwa ɗan adam hidima. Wasu sababbin sababbin abubuwa na baya-bayan nan na iya rage amfani da helium, amma helium har yanzu yana da mahimmanci don aikin kayan aikin MRI.
2. Helium-neon Laser: Helium-neon Laser shine haske mai haske na monochromatic tare da babban haske, kyakkyawan shugabanci da makamashi mai mahimmanci. Gabaɗaya magana, ƙananan ƙarfin helium-neon Laser ba shi da wani lahani ga jikin ɗan adam, don haka ana amfani da shi sosai a aikin asibiti. Abubuwan aiki na helium-neon Laser sune helium da neon. A cikin maganin likita, ana amfani da laser helium-neon maras ƙarfi don haskaka wuraren kumburi, wuraren da ba su da santsi, wuraren da suka yi rauni, raunuka da sauransu. Yana da anti-mai kumburi, anti-itching, gashi girma, inganta ci gaban granulation da epithelium, da kuma accelerates warkar da raunuka da kuma ulcers. Ko da a fannin ilimin likitanci, an yi laser helium-neon a matsayin "kyakkyawan kayan aiki". Helium-neon Laser kayan aiki shine helium da neon, wanda helium shine karin gas, neon shine babban iskar gas.
3.Argon-helium wuka: argon helium wuka ne fiye da amfani a asibiti kayan aikin likita, shi ne argon helium sanyi kadaici fasahar amfani a cikin likita filin crystallization. A halin yanzu, yawancin asibitocin gida suna da sabon samfurin argon helium wuka cryotherapy cibiyar. Ka'idar ita ce ka'idar Joule-Thomson, watau tasirin iskar gas. Lokacin da iskar argon ke fitowa da sauri a cikin tip ɗin allura, ƙwayar cuta za a iya daskare ta zuwa -120 ℃ ~ -165 ℃ a cikin daƙiƙa goma. Lokacin da helium ya fito da sauri a saman allura, yana samar da saurin sakewa, yana sa ƙwallon kankara ya narke da sauri kuma ya kawar da ciwon daji.
4, Gano Tsantsar Gas: Ganewar leak ɗin helium yana nufin tsarin amfani da helium azaman iskar gas don gano ɗigogi a cikin fakiti daban-daban ko tsarin rufewa ta hanyar auna maida hankali lokacin da ya tsere saboda yabo. Duk da yake wannan fasaha ba wai kawai ana amfani da ita a masana'antun magunguna da na'urorin likitanci ba, ana amfani da ita sosai a wasu fannoni. Idan ya zo ga gano leak ɗin helium a cikin masana'antar harhada magunguna, kamfanoni waɗanda za su iya samar da ingantaccen sakamako mai ƙima na iya haɓaka ingancin tsarin isar da magunguna. Yana adana kuɗi da lokaci kuma yana inganta aminci; a cikin masana'antar na'urorin likitanci, babban abin da aka fi mayar da hankali shine gwajin ingancin fakitin. Gwajin ruwan helium yana rage haɗarin gazawar samfur ga marasa lafiya da ma'aikatan kiwon lafiya, gami da haɗarin abin alhaki na samfur ga masana'antun.
6. Maganin asma: Tun daga shekarun 1990, an yi nazari akan gaurayawan helium-oxygen don maganin asma da cututtuka na numfashi. Bayan haka, yawancin bincike sun tabbatar da cewa gaurayawan helium-oxygen suna da tasiri mai kyau a cikin asma, COPD, da cututtukan zuciya na huhu. Haɗin hawan helium-oxygen mai ƙarfi zai iya kawar da kumburin hanyoyin iska. Shakawar cakuda helium-oxygen a wani matsa lamba na iya zubar da mucous membrane na trachea ta jiki da inganta fitar da zurfafan phlegm, cimma tasirin anti-kumburi da fata.
