1. Medical apparatus (1) comprising:
at least one machine (2) for extracorporeal blood treatment having:
at least a blood treatment unit (3);an extracorporeal blood line (4) having a withdrawal branch (5) adapted to withdraw blood from a patient access (6) and to bring the withdrawn blood to the blood treatment unit (3) and a return branch (7) adapted to bring the blood from the blood treatment unit (3) to the patient;at least one hematocrit sensor (8) associated to the extracorporeal line (4) and adapted to provide a measure related to a hemoglobin value in the blood circulating in the extracorporeal blood line (4); a control unit (9); at least one storage memory (10) for storing measures related to the hemoglobin value, each measure being made through one of the hematocrit sensors (8) of said machine (2) and each corresponding to different treatment sessions of patients on said machine (2);the control unit (9) being configured for performing the following steps:
taking from the storage memory (10) a plurality of measures related to the hemoglobin value, each measure being made through one of the hematocrit sensors (8) of said machine (2) at different patient treatment sessions, said plurality of measures relating to the same patient; receiving at least an actual control hemoglobin value relating to the same patient, said actual control value being measured at a monitoring time; said actual control hemoglobin value being a real absolute value of the hemoglobin measured through laboratory measurements; determining a correcting factor function of a difference between a prefixed number of measures made through the hematocrit sensors (8) and the actual control hemoglobin value, said correcting factor allowing obtaining an actual hemoglobin value by varying at least the last measure made through the sensor by means of the correcting factor. |
