1. A blood treatment machine comprising:
a treatment module including a structure for releasably coupling with a dialyzer, the treatment module including: (i) a first pressure transducer positioned to abut against a first membrane of a first pressure detection chamber of the dialyzer while the dialyzer is coupled with the treatment module and (ii) a second pressure transducer positioned to abut against a second membrane of a second pressure detection chamber of the dialyzer while the dialyzer is coupled with the treatment module,
wherein the first and second pressure transducers are reconfigurable between: (i) a first position in which the first and second pressure transducers are retracted and (ii) a second position in which the first and second pressure transducers are extended to abut against the first and second membranes respectively.
