摘要:
A method for priming a hemodialysis treatment includes (i) providing a sorbent cartridge for cleaning spent dialysate fluid returning from a dialyzer; (ii) preparing a batch of dialysate in a quantity commensurate with being recycled through the sorbent cartridge multiple times; (iii) priming a dialysate circuit in fluid communication with the dialyzer using the batch of dialysate; and (iv) reversing a blood pump at least one time to prime a blood circuit in fluid communication with the dialyzer using a biologically safe fluid other than dialysate.
