Ukukhutshwa okuLawulwayo kokuhanjiswa kweziyobisi: Isikhokelo esiBanzi 

Ukuhanjiswa kweziyobisi ezilawulwayo Iinkqubo ziyilelwe ukukhupha amayeza ixesha elide, zibonelela ngeenzuzo ezininzi kwiindlela eziqhelekileyo zokuhanjiswa kwechiza. Ezi nkqubo zigcina ugxininiso lwamachiza ngaphakathi koluhlu lwezonyango, ukunciphisa imiphumo emibi kunye nokuphucula ukuthotyelwa kwesigulane. Eli nqaku lingena kwimigaqo, iintlobo, iinzuzo, kunye nokusetyenziswa kwe ukuhanjiswa kweyeza elilawulwayo, inika ingcaciso eneenkcukacha yale nkalo yokuvelisa izinto ezintsha.

Ukuqonda Ukukhululwa Okulawulwayo

Yintoni uKhupho oluLawulwayo?

Ukukhululwa okulawulwayo ibhekisa kwinkqubo yokuhanjiswa kwechiza ngesantya esimiselweyo kunye nendawo ngaphakathi emzimbeni. Ngokungafaniyo neendlela ezikhutshwa kwangoko, ezikhupha idosi yonke ngokukhawuleza, ukuhanjiswa kweyeza elilawulwayo Iinkqubo zandisa ukukhutshwa kweyeza kwiiyure, iintsuku, okanye iinyanga. Le ndlela inika umphumo wonyango ohambelanayo kunye nokunciphisa ukuphindaphinda kwe-dosing.

Imigaqo yoKhupho oluLawulwayo

Imigaqo emininzi ilawula uyilo kunye nomsebenzi we ukukhululwa okulawulwayo iinkqubo:

• Ukusasazwa: Ukukhutshwa kweziyobisi kulawulwa ngumlinganiselo apho iyeza lisasazeka ngepolymer matrix.
• Ukupheliswa: Ukukhutshwa kweziyobisi kulawulwa ngumlinganiselo apho i-polymer matrix inyibilika okanye ikhukulise.
• I-Osmosis: Ukukhutshwa kwechiza okuqhutywa ngumahluko woxinzelelo lwe-osmotic kwi-membrane evumayo.
• Ukhukuliseko: Ukukhutshwa kwechiza okubangelwa ukuthotywa ngokuthe ngcembe kwe-polymer matrix.

Iindidi zeeNkqubo eziLawulwayo zokuKhupha

IiNkqubo zeMatrix

Iinkqubo zematrix zibandakanya ukufakela iyeza ngaphakathi kwepolymer matrix. Ichiza likhutshwa mhlawumbi ngokusasazwa nge-matrix okanye ngokukhukuliseka kwe-matrix ngokwayo. Ezi nkqubo zilula ukwenza kwaye zinokulungiswa ukuze zinike iiprofayili ezahlukeneyo zokukhupha.

Iinkqubo zamadama

Iinkqubo ze-Reservoir zibandakanya i-core equkethe ichiza elijikelezwe yi-polymer membrane. Ichiza likhutshwa ngenwebu ngesantya esilawulwayo. Ezi nkqubo zibonelela ngolawulo oluchanekileyo malunga nokukhutshwa kwechiza kodwa kunokuba nzima ukwenza.

Iinkqubo zeOsmotic

Iinkqubo ze-osmotic zisebenzisa uxinzelelo lwe-osmotic ukulawula ukukhutshwa kweziyobisi. Iyeza liqulethwe ngaphakathi kwenwebu engene kancinci, kwaye amanzi atsalwa kwinkqubo nge-osmosis. Oku kudala uxinzelelo olutyhala iyeza liphume ngentunjana encinci. Iinkqubo ze-Osmotic zibonelela ngokuqikelelwa kakhulu kunye nokukhutshwa kwechiza okufanayo.

Iinkqubo erodible

Iinkqubo ezibolayo zisebenzisa iipolymers ezonakalise okanye zikhukulise ngokuhamba kwexesha, zikhupha ichiza njengoko ipholima yophuka. Ezi nkqubo zihlala zisetyenziselwa ukuhanjiswa kweziyobisi ixesha elide.

Izinto eziluncedo ngoKhupho oluLawulwayo

UNyango oluFanelekileyo oluphuculweyo

Amanqanaba angaguqukiyo amachiza akhulisa iziphumo zonyango kwaye athintele amaxesha okuxinana kweziyobisi ezingaphantsi konyango okanye eziyityhefu.

Ukuhanjiswa kweziyobisi ekuJoliswe kuzo

Abanye ukukhululwa okulawulwayo iinkqubo zingayilwa ukuhambisa iziyobisi ngokuthe ngqo kwizicubu okanye izitho ezithile, ukwandisa ukusebenza kakuhle kunye nokunciphisa ukubonakaliswa kwenkqubo. Qwalasela uphando oluqhubekayo kumaziko afana IZiko loPhando ngoMhlaza laseShandong Baofa, egxininisa kunyango olujoliswe kuyo kwizifo ezahlukahlukeneyo.

Usetyenziso loKhupho oluLawulwayo

Izifo zentliziyo

Ukukhululwa okulawulwayo iifomyula zisetyenziselwa ukuhambisa amayeza oxinzelelo lwegazi, i-angina, kunye nezinye iimeko ze-cardiovascular, ukuqinisekisa ukulawula uxinzelelo lwegazi kunye nokunciphisa umngcipheko wokuhlaselwa yintliziyo kunye nokubetha.

Isifo seswekile

I-insulin kunye namanye amayeza eswekile ahlala esetyenziswa kusetyenziswa ukukhululwa okulawulwayo iinkqubo zokugcina amanqanaba e-glucose ezinzile kunye nokuphucula ulawulo lwe-glycemic.

Ulawulo lweentlungu

Ukukhululwa okulawulwayo i-opioids kunye nezinye ii-analgesics zibonelela ngesiqabu seentlungu eziqhubekayo, ukunciphisa imfuno yokudosa rhoqo kunye nokunciphisa umngcipheko wokuba likhoboka.

Unyango lomhlaza

Ukukhululwa okulawulwayo Iziyobisi zechemotherapy zinokujolisa kwiiseli zomhlaza ngempumelelo ngakumbi, ukunciphisa umonakalo kwizicubu eziphilileyo kunye nokunciphisa iziphumo ebezingalindelekanga. IZiko loPhando ngoMhlaza laseShandong Baofa ibandakanyeka ngokusebenzayo kuphando olunxulumene nokusetyenziswa kokukhululwa okulawulwayo kunyango lomhlaza.
