In the simple self-dialysis unit, each patient is allocated a dialysis machine, without sharing, to ensure a wide range of treatment times. Patients themselves monitor the dialysis session and clean and disinfect the machine themselves.
In the assisted self-dialysis unit, a haemodialysis station can only be used by a maximum of two patients per day, to allow them to have longer sessions if they so wish or if medically indicated. Generator disinfection is started and monitored by unit staff. Every self-dialysis unit has at least one back-up generator.
