Convection-Enhanced Delivery (CED) yog ib txoj kev xa tshuaj tshiab uas tsim los kom kov yeej cov kev txwv ntawm kev nthuav dav ib txwm muaj-cov txheej txheem raws li cov txheej txheem. Los ntawm kev tsim kom muaj cov dej ntws tawm hauv cov ntaub so ntswg, CED ua kom ncaj qha thiab txawm tias faib cov neeg ua haujlwm kho mob mus rau thaj chaw tsom, ua kom muaj txiaj ntsig zoo ntawm kev kho mob. Lub tshuab no tau txais kev saib xyuas rau nws lub peev xwm los txhim kho kev nkag mus ntawm cov tshuaj sib sib zog nqus rau hauv cov ntaub so ntswg, ua kom muaj zog hauv zos ntau dua thiab cov txiaj ntsig kho tau zoo dua.
Cov ntsiab cai ntawm CED Technology
Ntawm qhov tseem ceeb ntawm CED thev naus laus zis yog kev siv cov microcatheters los txhaj tshuaj rau hauv cov ntaub so ntswg thiab tsim kom muaj cov dej ntws los ntawm kev siv cov kev txhawb nqa, qis - siab gradients. Qhov no convective flow propels therapeutic agents los ntawm cov chaw extracellular, tso cai rau lawv los npog cov ntim loj ntawm cov ntaub so ntswg. Tsis zoo li cov txheej txheem ib txwm siv los ntawm kev nthuav dav nkaus xwb, CED ua kom cov tshuaj muaj zog ntau ntxiv hauv thaj chaw lub hom phiaj thaum txo qis kev raug mob thiab cuam tshuam cov kev mob tshwm sim.
Kev siv CED
- Catheter Design thiab Placement:Lub catheter yog cov cuab yeej tseem ceeb rau kev ua tiav CED. Feem ntau, ntau- chaw nres nkoj tsim yog siv los xyuas kom meej tias cov tshuaj tso tawm tsis sib xws. Txoj kab uas hla, qhov ntev, thiab qhov chaw nres nkoj ntawm lub catheter yuav tsum tau ua kom zoo raws li cov ntawv thov tshwj xeeb kom haum rau cov ntaub so ntswg sib txawv.
- Pressure Control Systems:Txhawm rau tsim kom muaj qhov ruaj khov convective ntws, precision siab tswj tshuab yog qhov tseem ceeb. Cov tshuab no kho qhov siab thiab cov tshuaj txaus txaus raws li qhov tiag - lub sij hawm tawm tswv yim, kom ntseeg tau tias cov tshuaj kho tau muab faib rau hauv cov ntaub so ntswg raws li tau npaj tseg. Cov cuab yeej CED niaj hnub no feem ntau nruab nrog lub khoos phis tawj tswj hwm kom tswj hwm ntau yam tsis raug thaum lub sijhawm xa khoom.
- Kev Xaiv Tshuaj:Tsis yog txhua yam tshuaj uas tsim nyog rau CED. Qhov hnyav molecular, formulation, thiab biocompatibility ntawm cov tshuaj yuav cuam tshuam rau nws lub zog thiab kev ua tau zoo nyob rau hauv lub extracellular chaw. Yog li ntawd, rau cov hom phiaj tshwj xeeb, cov tshuaj feem ntau yuav tsum tau kho kom zoo kom siv tau qhov zoo ntawm CED technology.
- Daim Ntawv Qhia thiab Saib Xyuas:Hauv kev siv cov tswv yim, CED thev naus laus zis feem ntau ua ke nrog cov duab tiag tiag - lub sijhawm los xyuas kom meej qhov kev tso chaw ntawm lub catheter thiab muab cov tshuaj kom raug. Los ntawm cov txheej txheem kev yees duab xws li MRI thiab CT, cov kws kho mob tuaj yeem saib xyuas qhov sib txawv ntawm cov tshuaj hauv lub sijhawm tiag tiag - thiab kho cov khoom xa tuaj raws li qhov xav tau los xyuas kom meej qhov kev kho mob zoo.
Kev siv CED hauv kev kho mob ntawmCNS mob
- Tus kab mob Parkinson:CED tab tom tshawb nrhiav rau kev xa khoom ntawm cov tshuaj neurotrophic (piv txwv li, GDNF) los txhawb kev muaj sia nyob thiab kev ua haujlwm zoo ntawm dopaminergic neurons. Cov kev tshawb fawb qhia tias CED-kev kho kom haum xeeb ntawm cov kab mob neurotrophic tuaj yeem txo cov tsos mob ntawm tus kab mob Parkinson thiab ncua kev kis kab mob.
- Alzheimer's Disease:Hauv kev tshawb fawb txog kab mob Alzheimer, CED tau ua haujlwm los xa cov tshuaj tiv thaiv kab mob, enzymes, lossis cov tshuaj kho cov kab mob uas tsom mus rau kev tshem tawm ntawm -amyloid plaques lossis txo cov protein sib sau ua ke. Cov kev tshawb fawb no qhia tau hais tias muaj peev xwm tseem ceeb ntawm CED hauv kev kov yeej cov ntshav - lub hlwb teeb meem thiab txhim kho kev kho mob.
- Ntau Sclerosis:Cov kws tshawb fawb siv CED txhawm rau xa cov tshuaj tiv thaiv kab mob thiab cov tshuaj tiv thaiv neuroprotective los txo qhov mob thiab txhawb kev kho myelin. Cov kev tshawb pom ua ntej qhia tau hais tias CED- xa cov tshuaj tuaj yeem pom muaj txiaj ntsig zoo hauv kev tswj kev mob tshwm sim.
- Spinal Cord Injury:CED tseem tab tom tshawb nrhiav rau kev kho mob ntawm tus txha caj qaum, pab txhawb kev tsim cov paj hlwb thiab kev ua haujlwm rov qab los ntawm kev xa ncaj qha ntawm cov kws kho mob mus rau qhov chaw raug mob. Cov kev tshawb fawb tau pom tias CED tuaj yeem ua kom cov tshuaj muaj zog ntau ntawm qhov chaw raug mob, yog li txhim kho cov txiaj ntsig kev kho mob.
Prisys Biotech's Leadership in CED Technology
Prisys Biotech tau tsim thawjintraoperative magnetic resonance imaging (iMRI) -coj lub hlwb precision navigation thiab xa systemhauv Asia. Qhov no advanced system, kev koom ua ke nrogCT, DSA, ultrasound, thiab lwm yam technologies, ua kom yooj yim rau kev siv CED, tsim ib qho kev qhia dav dav ntawm cov hom phiaj kev xa khoom zoo rau lub cev thiab cov ntaub so ntswg. Prisys Biotech's CED thev naus laus zis yog nyob rau hauv pem hauv ntej ntawm kev tsim kho tshiab, siv siab - kev qhia meej meej muab los ntawm iMRI los saib xyuas kev faib tshuaj thiab kev nthuav dav hauv lub sijhawm tiag tiag - lub sijhawm phais. Qhov no ua kom ntseeg tau tias cov neeg ua haujlwm kho mob tau ncav cuag lawv lub hom phiaj, npog cov ntaub so ntswg loj dua thiab txhim kho cov txiaj ntsig kho mob.
Tsis tas li ntawd, Prisys Biotech's CED system tau hloov zuj zus mus rau hauv ib qho kev ua tiav ntawm cov phiaj xwm xa khoom siv thev naus laus zis uas haum rau ntau yam kabmob thiab cov ntaub so ntswg. Cov kev nce qib no tsis yog tsuas yog tsav cov kev tshawb fawb txog kev tshawb fawb ntawm CED thev naus laus zis tab sis kuj tsim Prisys Biotech ua tus thawj coj hauv kev xa tshuaj precision hauv CNS domain.
