AIM: To develop a body counterpulsation measuring and training system for the heart function improvement, which can be used to measure the heart rate, oxygen saturation and strength of the pulse wave, to display the wave and to store the data. METHODS: On the basis of bio feedback principle, the chest pressure was controlled by the synchronic training of the respiration with the heart cycle and the heart function was improved through the counterpulsation. Moreover, the device combined the measurement of physiology with the training of respiration, so the training results could be directly displayed. RESULTS: Device was found to have the function of tranquilizing moods and heightening spirits. The error rate was smaller than ±1% between 75% and 99% of the oxygen saturation, which was confirmed by Bio Tek, an imported oximetry simulator, indicating that the device had accurate measurement and good training results. CONCLUSION: Device is simple in structure and easy to use, especially for the purpose of home health care.
