HPMC ee dhibcaha indhaha

Hydroxypropyl methyl celluloseHPMC waxaa loo isticmaalaa in lagu soo saaro dhibcaha indhaha, oo ay ku jiraan tillaabooyinka soo socda: marka hore, qaybaha soo socda ee miisaanka la doortay alaabta ceeriin, hydroxypropyl methyl cellulose HPMC gudaha 3 gabal, 40℃ilaa 70℃biyaha lagu duro 300-800, si loogu daro hydroxypropyl methyl celluloseHPMCBiyaha kor ku xusan, in ka badan iyo in ka badan 30 daqiiqo, ka dib si siman u faafay, qaadashada ilaalinta heerkulka hooseeya, ayaa xaqiijiyay heerkulka kaydinta waxaa lagu xakameynayaa 0℃-30℃, kaydsan in ka badan 12 saacadood, waa la isticmaali karaa; Ka dib u qaado 150 qaybood oo miisaan biyo ah si aad ugu milanto walxaha kale ee cayriin iyo kuwa caawiya ee dhibcaha indhaha, oo si siman ugu qas hydroxypropyl methyl cellulose diyaarsan.HPMCxal heerkulka qolka. Ugu dambeyntii, ku dar biyo xalalka isku dhafka ah ilaa inta ay le'eg tahay xajmiga xajmiga / mugga ee hydroxypropyl methyl cellulose HPMC waa 0.3%, oo si siman u walaaq si aad u hesho dhibcaha indhaha ee dhammaatay. Hal-abuurku wuxuu heli karaa hydroxypropyl methyl celluloseHPMCxalinta viscosity iyo hufnaanta ugu badan, xalli dhibaatada roobka ee sheyga dhibcaha ugu dambeeya ee isha, oo wanaaji tayada alaabta.

Foomka dhibcaha indhaha

Qiyaasta boqolkiiba miisaanka qayb kasta oo ka mid ah dhibcaha indhaha ayaa ahaa: povidone iodine 0.1% ~ 0.5%, lidocaine 0.5% ~ 1%, hydroxypropyl methyl cellulose HPMC 0.5% ~ 1.5%, flumeilon 0.05% ~ 0.15%, sodium ~ hyaluronate 00.05% %. Hababka diyaargarowga ayaa lagu sharaxay, biyo la miiray siday u kala horreeyaan povidone iodine, lidocaine, masduulaaga fluorine, hydroxypropyl methyl cellulose, sodium hyaluronate oo laga sameeyay kala dirida xalalka povidone iodine, xal lidocaine, xal masduulaagii fluorine, xal hydroxypropyl methyl cellulose, sodium hyaluronate xal, ka dibna povidone xal, xal lidocaine, xal masduulaagii fluorine iyo / ama iyo hydroxypropyl methyl cellulose xal / ama sodium hyaluronate xal isku qasan si ay u sameeyaan xal isku dhafan ka dib diyaarinta dhibcood indhaha. Hal-abuurku waxa uu si weyn u ballaadhiyaa tirada ballaadhan ee dhibcaha indhaha waxana uu yareeyaa xanaaqa kornea.
