Device for remotely monitoring a patient with chronic heart failure, and associated system and method

A device for remotely monitoring a patient suffering from chronic heart failure, said device comprising:

• a first communication interface configured to communicate with a weighing scale in order to obtain a measurement of the weight of the patient;
• a second communication interface configured to communicate with an oxygen meter in order to obtain measurements of the heart rate and of the blood oxygen saturation level of the patient;
• a third communication interface configured to transmit an alert to the patient;
• and
• a computer connected to the three interfaces, comprising a storage memory configured to store the measurements obtained, the computer being configured to trigger an alert when the measurements obtained indicate a probable onset of cardiac decompensation in the patient;
• the computer being configured to:
• obtain a nominal weight of the patient and predetermined values comprising:
• a first weight limit increase;
• a second weight limit increase strictly less than the first weight limit increase;
• a first blood oxygen saturation level;
• a second blood oxygen saturation level strictly greater than the first blood oxygen saturation level;
• a first heart rate;
• and
• a second heart rate strictly less than the first heart rate,
• determine, from the measurements obtained, whether any one of the following first conditions is fulfilled:
• the weight has increased more than the first weight limit increase relative to the nominal weight of the patient;
• the weight has increased, between two measurements taken over a predetermined period strictly greater than 2 days, by a value strictly greater than the first weight limit increase;
• the blood oxygen saturation level is strictly less than the first blood oxygen saturation level;
• the heart rate is strictly greater than the first heart rate;
• determine that an onset of cardiac decompensation is probable when at least one of the first conditions is fulfilled;
• determine, from the measurements obtained, whether any one of the following second conditions is fulfilled:
• the weight has increased between two measurements taken over 2 consecutive days by a value strictly greater than the second weight limit increase;
• the blood oxygen saturation level is strictly less than the second blood oxygen saturation level;
• the heart rate is strictly greater than the second heart rate,
• determine that an onset of cardiac decompensation is probable when two of the second conditions are fulfilled simultaneously, while none of the first conditions is fulfilled.
