Cov ntaub ntawv no tau dhau los ntawm kev lees paub zoo raws li ISO 10993 cov qauv rau cytotoxicity thiab sensitization. Cov twj tso kua mis ua raws li txoj cai kuj muaj cov ntawv pov thawj xws li CE (Medical Directive), RoHS, thiab feem ntau FDA 510 (k) kev tshem tawm rau cov ntawv thov tshwj xeeb38.

III. Cov Ntawv Thov Tseem Ceeb Hauv Cov Chaw Kho Mob Uas Tsis Muaj Mob

1. Cov Khoom Siv Kuaj Mob thiab Kuaj Mob

• Kev Lim Dej Nqus Tsev: Chemker series PTFE diaphragm twj tso kua mis tsim kom muaj txog li -750mmHg lub tshuab nqus tsev rau kev lim dej huv hauv cov kab lis kev cai cell lossis kev npaj reagent, nrog rau kev ua haujlwm tsis muaj roj tshem tawm cov qauv ua qias tuaj2.

• Cov Cuab Yeej Siv Los Ntsuas: Cov twj Mini-Dia-Vac muab cov qauv roj uas tsis muaj kev co hauv cov cuab yeej ntsuas ntshav thiab cov cuab yeej ntsuas pa, qhov no tseem ceeb rau kev nyeem tau raug1.

2. Kev Sib Koom Tes ntawm Cov Khoom Siv Kho Mob

• Cov Twj Tso Kua Mis: Cov twj tso kua mis DC diaphragm uas tsis muaj txhuam (piv txwv li, SEAFLO SFDP1 series) ua rau muaj kev xa tshuaj kom raug, tsis muaj pulsed ntawm 120 PSI nrog qhov tseeb ntawm kev ntws ≤ ± 2%, qhov tseem ceeb rau kev kho mob chemotherapy lossis kev noj tshuaj insulin8.

• Cov Voj Voog Sab Nraud: Hauv cov twj tso ntshav lossis cov tshuab dialyzer, cov twj DC kaw ruaj ruaj tiv thaiv cov ntshav kom tsis txhob sib cuag nrog cov khoom sab nraud thaum tiv taus kev ua kom tsis muaj pa dej (121°C)57.

3. Cov Khoom Siv Nqa Tau Thiab Cov Khoom Siv Saib Xyuas

• Cov Chav Kuaj Mob Tes: Cov twj me me zoo li Feiyinsi's 32g DC qauv (0.4L/min ntws) ua rau muaj kev tsim qauv me me, siv roj teeb rau kev tshuaj ntsuam ntshav hauv daim teb lossis cov tshuab ua pa.

• Kev Xa Tshuaj Uas Hnav Tau: Cov twj tso kua mis qis-voltage (3V-5V) txhawb nqa cov tshuaj insulin uas taug kev nrog kev ua haujlwm ntsiag to heev (<40dB)8.
