Respiratory muscle strengthening device

A respiratory muscle strengthening device comprising:

• a respiration detecting unit configured to generate an inhalation start signal correspondingly at an inhalation start time when a patient inhales air or generating an exhalation start signal correspondingly at an exhalation start time when the patient exhales air;
• an electric muscle stimulator capable of being attached to respiratory muscles of a patient and configured to stimulate the respiratory muscles based on the inhalation start signal or the exhalation start signal,
• wherein the respiration detecting unit configured to transmit the inhalation start signal or the exhalation start signal to the electric muscle stimulator;
• a receptor pad capable of being attached to the respiratory muscles of the patient and configured to detect contraction and relaxation degrees and times of the respiratory muscles;
• a communication unit for converting either spontaneous breathing of the patient or a respiratory stimulation signal applied from an outside to the inhalation start signal or the exhalation start signal;
• and
• an operation control unit configured to generate a first driving control signal or a second driving control signal correspondingly to the inhalation start signal or the exhalation start signal obtained by the communication unit.
