• Da'irori na waje: A cikin famfunan jini ko na'urorin dialyzers, famfunan DC da aka rufe da ganye suna hana jini shiga da gurɓatattun abubuwa na waje yayin da suke jure wa tururi (121°C)57.

3. Na'urorin Kulawa Masu Ɗauka da Ɗauka

• Na'urorin Ganewa na Hannun: Ƙananan famfo kamar samfurin Feiyinsi na DC mai nauyin 32g (0.4L/min kwarara) suna ba da damar ƙira mai ƙarfi da batir don nazarin jinin fili ko na'urorin numfashi3.

• Isar da Magani Mai Amfani: Famfon ruwa masu ƙarancin ƙarfin lantarki (3V-5V) suna tallafawa facin insulin na motsa jiki tare da aiki mai natsuwa (<40dB)8.
