Nws tsis pub leejtwg paub tias tom qab siv cov cuab yeej kho mob thiab cov khoom lag luam, lawv yuav tsum tau ua tib zoo ua kom zoo txhawm rau tshem tawm txhua yam kab mob. Ntau txoj kev siv rau qhov no. Tom qab kev kho mob nrog cov tshuaj detergents raws li Methodological cov lus pom zoo ntawm Ministry of He alth 28-6 / 13 ntawm 1982-08-06, yuav tsum tau ua ib qho kev kuaj phenolphthalein.
Sampling assignment
Txhawm rau ntsuas qhov ua tau zoo ntawm kev ua haujlwm (laundering) los ntawm qhov chaw ntawm cov twj paj nruag ntawm cov tshuaj ntxuav tes thiab lwm yam kab mob, cov kev daws teeb meem sib txawv tau npaj. Kev kuaj phenolphthalein tsuas yog ib qho ntawm cov theem ntawm kev kuaj xyuas qhov muaj cov seem ntawm cov tshuaj detergents, uas yog, lawv cov alkaline Cheebtsam. Rau nws qhov kev siv, ib qho kev daws ntawm cov tshuaj no yog npaj. Raws li cov lus pom zoo Methodological, nws yog ib qho tsim nyog yuav tau ua 1% tshuaj phenolphthalein. Tam sim ntawd tom qab nws npaj, lawv pib ntsuas cov cuab yeej ua haujlwm zoo.
YPhenolphthalein testing
Nws tab tom uanyob rau hauv ob peb theem. Ua ntej tshaj plaws, 2-3 tee ntawm cov tshuaj phenolphthalein yog siv rau qhov ntsuas. Nws yuav tsum tau nkag mus rau cov pob qij txha ntawm cov khoom txav thiab qhov chaw ntawm kev sib cuag nrog lub qhov txhab. Qhov no yog vim muaj kev pheej hmoo ntawm kev sib cuag ntawm cov tshuaj phem thiab cov organic tshuaj nrog tus neeg mob cov ntshav.
Nyob rau theem tom ntej, tus kws pab kuaj xyuas cov qib ntawm cov tshuaj staining. Qhov kev ntsuam xyuas phenolphthalein qhia qhov sib txawv ntawm alkalis. Cov tsos ntawm cov xim liab qhia tias muaj cov tshuaj ntxuav tsis zoo surfactants. Lub xub ntiag ntawm cov qauv brownish qhia tias muaj cov xeb, nrog rau cov tshuaj chlorine-muaj oxidizing cov neeg ua haujlwm. Hauv lwm qhov xwm txheej, cov xim muaj xim liab-lilac ntxoov. Yog tias pom qhov hloov pauv ntawm cov xim ntawm cov qauv, tag nrho cov khoom siv kho mob raug xa mus rau rov ntxuav nrog dej ntws. Tom qab ntawd lawv raug kho nrog dej distilled.
Tom qab ntxuav, cov twj paj nruag tau muab tso rau hauv cov thawv tshwj xeeb nrog cov tshuaj ntxuav. Lawv ua cov kev kho mob ua ntej kom tsis muaj menyuam. Kev saib xyuas tshwj xeeb yog them rau qhov zoo ntawm kev tu catheters thiab lwm yam khoom hollow. Txhawm rau ua qhov no, kev sim phenolphthalein yog nqa tawm hauv qhov ntsuas los ntawm kev qhia txog kev daws teeb meem uas siv lub pipette lossis syringe. Cov reagent yuav tsum nyob hauv cov khoom rau 30-60 vib nas this. Tom qab ntawd nws yog nchuav rau ntawm daim ntaub so ntswg thiab muab piv nrog cov ntsuas.
Sample conditions
Ua raws li cov cai tam sim no, phenolphthalein kuaj tau ua nyob rau hauv cov tuam tsev (1% ntawmcov cuab yeej ua tiav ib txhij, tab sis tsis pub tsawg dua 3 units - ua ntej ua ntej thauj khoom rau kom tsis muaj menyuam); centralized sterilization (1% ntawm txhua yam khoom uas tau ua tiav ib zaug). Cov txiaj ntsig ntawm kev tswj hwm tau sau tseg hauv daim ntawv No. 366/U.
Kev tswj hwm los ntawm cov kws kho mob tshwj xeeb ntawm cov tshuaj tua kab mob thiab cov chaw huv-tshuaj tiv thaiv kab mob rau kev ntxuav ua ntej kom tsis muaj menyuam hauv tsev kho mob tau ua txhua lub hlis twg. Nrog kev ua haujlwm tsis zoo ntawm cov cuab yeej phais thiab cov cuab yeej kho mob, kev kis mob ntawm qhov txhab thaum lub sijhawm ua haujlwm, kev txhim kho kab mob siab thiab AIDS yog ua tau.
