Device enabling an individual to self-monitor his breathing in order to assist in the control of a radiotherapy or imaging unit

Self-monitoring device enabling an individual to self-monitor his breathing in order to assist in the control of a radiotherapy or imaging unit comprising

• means for acquiring at least one signal, known as the current metabolic volume signal, which is representative of the variation in the volume of air contained in the lungs of an individual during his breathing cycles,
• a signal-processing unit connected to said acquisition means, said processing unit comprising means for accessing at least one value, known as the rest value, which is representative for an individual of a breathing cycle during rest, and at least one value, known as the setpoint value, which is representative for an individual of a predetermined target inhalation and/or exhalation,
• at least one interface for communication with an individual, said communication interface being connected to said signal-processing unit and comprising communication means capable of communicating a signal to the individual,
• said self-monitoring device being characterised in that the signal-processing unit
• comprises means for detecting regular breathing during rest by comparing the current metabolic volume signal with said rest value(s)
• and is capable of controlling said communication means in order that said means transmit a signal that is representative of said setpoint value(s) if said signal-processing unit detects regular breathing during rest.
