Musanagwiritse Ntchito:
1. Yang'anani chivundikiro cha chubu ndi thupi la chubu la chokololera.Ngati chivundikiro cha chubu ndi chomasuka kapena thupi la chubu lawonongeka, ndizoletsedwa kugwiritsa ntchito.
2. Yang'anani ngati mtundu wa chotengera chosonkhanitsira magazi ukugwirizana ndi mtundu wa chitsanzo chomwe chiyenera kusonkhanitsidwa.
3. Dinani ziwiya zonse zosonkhanitsira magazi zomwe zili ndi zowonjezera zamadzimadzi kuti mutsimikizire kuti zowonjezerazo sizikhala mu kapu yamutu.
Kugwiritsa:
1. Sankhani malo obowola ndikulowetsa singano bwino kuti musayende bwino.
2. Pewani "kubwerera m'mbuyo" panthawi ya puncture: posonkhanitsa magazi, yendani mofatsa pamene mukumasula lamba wokakamiza.Osagwiritsa ntchito bandi yolimba kwambiri kapena kumangirira bandi yopondereza kwa mphindi yopitilira 1 nthawi iliyonse pakubowola.Osamasula bandesi ya kuthamanga magazi pamene kutuluka kwa vacuum chubu kwayima.Sungani mkono ndi vacuum chubu pamalo otsika (pansi pa chubu ndi pansi pa chivundikiro chamutu).
3. Pamene chubu pulagi puncture singano anaikapo mu zingalowe chotengera magazi chotengera, modekha akanikizire singano mpando wa chubu pulagi puncture singano kupewa "singano bouncing".
Pambuyo pakugwiritsa ntchito:
1. Musatulutse singano ya venipuncture pambuyo pa vacuum ya chotengera chotengera magazi chatha, kuti muteteze nsonga ya singano yosonkhanitsira magazi kuti isadonthe magazi.
2. Pambuyo posonkhanitsa magazi, chotengera chotengera magazi chiyenera kusinthidwa nthawi yomweyo kuti zitsimikizire kusakaniza kwathunthu kwa magazi ndi zowonjezera.
