Cov kev daws teeb meem uas muaj lub siab osmotic tib yam li cov kua hauv lub cev yog hais tias yog isotonic nrog lub cev kua. Cov kua dej hauv lub cev xws li cov ntshav thiab cov kua muag muaj osmotic siab sib xws nrog 0.9% Nacl lossis dextrose aqueous tov; Yog li, 0.9% Nacl lossis 5%, dextrose tov yog hu ua isosmotic lossis isotonic.
Ib qho piv txwv ntawm cov tshuaj isotonic yog dab tsi?
Isotonic cov kev daws teeb meem yog cov kua IV uas muaj cov ntsiab lus zoo sib xws ntawm cov khoom yaj hauv cov ntshav. Ib qho piv txwv ntawm cov tshuaj isotonic IV yog 0.9% Ib txwm Saline (0.9% NaCl).
Dab tsi yog isotonic tov ?
Ib qho tshuaj isotonic yog ib qho uas muaj qhov sib npaug li lwm qhov kev daws. Yog tias ob txoj kev daws teeb meem sib cais los ntawm ib qho semipermeable, cov tshuaj yuav ntws mus rau hauv qhov sib npaug. Raws li qhov concentration ntawm cov kuab tshuaj thiab cov kuab tshuaj yog tib yam.
Tus neeg sawv cev tonicity yog dab tsi?
Nrhiav ib qho loj ntawm cov tshuaj tonicity excipients ntawm Spectrum Chemical tsim txhawm rau txo qis hauv zoslos ntawm kev tiv thaiv osmotic shock ntawm qhov chaw ntawm daim ntawv thov. Feem ntau ntxiv rau kev txhaj tshuaj, qhov muag lossis qhov ntswg, cov khoom siv no suav nrog cov tshuaj potassium chloride, mannitol, thiab ntau dua.
3 hom kev daws teeb meem yog dab tsi?
Kev piav qhia:
- Solid solution.
- kua tshuaj.
