Bakeng sa bakuli ba nang le lefu la renal la ho qetela (ESRD), hemodialysis ke khetho e sireletsehileng le e sebetsang ea phekolo. Nakong ea phekolo, mali le dialysate li kopana le dialyzer (liphio tsa maiketsetso) ka lesela le nang le semi-permeable, e leng se lumellang phapanyetsano ea lintho tse tsamaisoang ke likhahla tsa mahloriso. Mochini oa hemodialysis o bapala karolo ea bohlokoa ho hloekiseng mali ka ho tlosa litšila tsa metabolism le li-electrolyte tse feteletseng ha o ntse o hlahisa li-ion tsa calcium le bicarbonate ho tloha dialysate ho kena maling. Sehloohong sena, re tla hlahloba lintlha tsa motheo tsa mochini oa hemodialysis le ho tataisa mokhoa oa ho khetha sesebelisoa sa boleng bo holimo ho etsa hore kalafo e be bonolo haholoanyane.

 

Ho utloisisa Mechini ea Hemodialysis

Mechini ea hemodialysis hangata e na le litsamaiso tse peli tsa mantlha: sistimi ea ho lekola taolo ea mali le sistimi ea phepelo ea dialysate. Sistimi ea mali e na le boikarabello ba ho laola phallo ea mali kantle ho mmele mme sistimi ea dialysate e lokisa tharollo ea dialysis e tšoanelehang ka ho kopanya concentrates le RO metsi ebe e tsamaisa tharollo ho dialyzer. Ho hemodialyzer, dialysate e etsa solute diffusion, penetration, and ultrafiltration le mali a mokuli ka lera le ka khonang ho phunyeletsa, 'me ka nako eo, mali a hloekisang a tla khutlela 'meleng oa mokuli ka mokhoa oa ho laola mali le tsamaiso ea dialysate e ntša metsi a litšila. Ts'ebetso ena e tsoelang pele ea libaesekele e hloekisa mali ka katleho.

Ka tloaelo, mokhoa oa ho lekola taolo ea mali o kenyelletsa pompo ea mali, pompo ea heparin, tlhahlobo ea khatello ea methapo le methapo, le sistimi ea ho lemoha moea. Likarolo tse ka sehloohong tsa mokhoa oa phepelo ea dialysis ke mokhoa oa ho laola mocheso, tsamaiso ea ho kopanya, tsamaiso ea degas, tsamaiso ea ho hlahloba conductivity, ho hlahloba ultrafiltration, ho lemoha ho lutla ha mali, joalo-joalo.

Mefuta e 'meli ea mantlha ea mechini e sebelisoang ho hemodialysis ke e tloaelehilengmochini oa hemodialysis (HD).le eamochine oa hemodiafiltration (HDF).. Ho sebelisoa mechine ea HDFdialyzer tse phahameng haholofana ka ts'ebetso e tsoetseng pele ea ho sefa --phatlalatso le convection ho matlafatsa ho tlosoa ha limolek'hule tse kholoanyane le lintho tse chefo le ho tlatsa li-ion tsa bohlokoa ka ts'ebetso ea phepelo ea phepelo.

Ke habohlokoa ho hlokomela hore sebaka se ka holimo sa lera sa dialyzer se lokela ho nkoa ka boemo bo itseng ba mokuli, ho akarelletsa boima ba 'mele, lilemo, boemo ba pelo, le ho fihlella ha methapo ea mali ha u khetha li-dialyzer. Kamehla buisana le tlhahiso ea ngaka ea setsebi ho fumana hore nadialyzer e loketseng.

 

Ho Khetha Mochini o Nepahetseng oa Hemodialysis

Tšireletseho le ho nepahala ke lintho tsa bohlokoa ka ho fetisisa. Lintlha tse ling tsa bohlokoa tseo u ka li nahanang ke tsena:

1. Likarolo tsa Tšireletso

Mochini o hloahloa oa hemodialysis o lokela ho ba le tlhahlobo e matla ea ts'ireletso le lisebelisoa tsa alamo. Litsamaiso tsena li lokela ho ba hlokolosi ka ho lekaneng ho lemoha maemo leha e le afe a sa tloaelehang le ho fana ka litlhokomeliso tse nepahetseng ho basebetsi.

Tlhokomelo ea nako ea 'nete ke tlhahlobo e tsoelang pele ea khatello ea methapo le methapo, sekhahla sa phallo, le likarolo tse ling tsa bohlokoa nakong ea dialysis. Litemoso tsa litsamaiso tsa lialamo bakeng sa litaba tse joalo ka moea o tsoang maling o feta khatello ea mali, kapa litekanyetso tse fosahetseng tsa ultrafiltration.

 2. Ho nepahala ha tshebetso

Ho nepahala ha mochini ho ama katleho ea kalafo 'me hangata ho hlahlojoa ke lintlha tse latelang:

Sekhahla sa Ultrafiltration: mochini o lokela ho laola ka nepo mokelikeli o tlositsoeng ho mokuli.

Tlhokomelo ea conductivity: ho netefatsa hore dialysate e maemong a nepahetseng a electrolyte.

Taolo ea mocheso: mochini o lokela ho boloka dialysate ka mocheso o bolokehileng le o phutholohileng.

 3. Sehokelo sa Mosebelisi

Sehokelo se bonolo sa basebelisi se ka ntlafatsa haholo boiphihlelo ho bakuli le basebelisi. Batla mechini e nang le li-control tse hlakileng le lipontšo tse hlakileng tse etsang hore ho be bonolo ho beha leihlo litekanyetso tsa kalafo.

4. Tlhokomelo le Tšehetso

Nahana ka bokhoni ba ts'ehetso ea tekheniki le lits'ebeletso tsa tlhokomelo bakeng sa moetsi oa mochini ea khethiloeng. Tšehetso e ka tšeptjoang e ka etsa bonnete ba hore litaba leha e le life li rarolloa hang-hang, ho fokotsa tšitiso ea phekolo.

 5. Ho Ikamahanya le Maemo

Mochini oa hemodialysis o tlameha ho latela litekanyetso tse nepahetseng tsa polokeho le boleng tse behiloeng ke mekhatlo ea taolo. Ho latela melao ena ho bohlokoa bakeng sa ho netefatsa polokeho ea mokuli le kalafo e sebetsang.

 

Mechini ea Tlholisano ea Hemodialysis le Moetsi

Themochini oa hemodialysis oa mohlala W-T2008-Bentsoe keChengdu Wesleye kopanya lilemo tse ka bang mashome a mararo tsa boiphihlelo ba indasteri le boqapi ba theknoloji. Mochini o etselitsoe ho sebelisoa litsing tsa bongaka mme o fumane lengolo la CE, ka theknoloji e tsoetseng pele, botsitso, polokeho ea mokuli le boiketlo, le ts'ebetso e bonolo bakeng sa basebetsi ba bongaka. E na le lipompo tse peli le kamore e nepahetseng ea phepelo-le-return-liquid-balance, moralo o ikhethang oa ho netefatsa ho nepahala ha ultrafiltration. Likarolo tsa bohlokoa tsa mochini li romelloa ho tsoa Europe le US, joalo ka li-valve tsa solenoid tse netefatsang taolo e nepahetseng ea ho bula le ho koala ha liteishene, le li-chips tse netefatsang tlhahlobo e nepahetseng le pokello ea data.

 

E tsoetseng pele tshireletso ya polokeho tsamaiso

Mochine ona o sebelisa tsamaiso e 'meli ea ho hlahloba le ho sireletsa moea, boemo ba mokelikeli le li-bubble detectors, tse ka thibelang ka katleho hore moea o potolohang mali o kene 'meleng oa mokuli ho thibela likotsi tsa moea. Ho phaella moo, mochine o na le lintlha tse peli tsa ho shebella mocheso le lintlha tse peli bakeng sa conductivity, ho netefatsa hore boleng ba dialysate bo bolokiloe nakong eohle ea phekolo. Sistimi ea alamo e bohlale e fana ka maikutlo a nako ea nnete mabapi le lintho tse sa tloaelehang nakong ea dialysis. Alamo ea acousto-optic e lemosa basebetsi hore ba arabe ka potlako litabeng leha e le life, ho matlafatsa tšireletso ea mokuli le katleho ea phekolo.

E ka fetoha habonolo lipakeng tsa mefuta ea HDF le HD nakong ea kalafo. Kenya ka li-dialyzer tse phahameng, tse thusang ho tlosoa ha limolek'hule tse khōloanyane maling, mochine o ntlafatsa katleho le boiketlo ba phekolo.
