| Abstract: | A Thoracic feedback based intelligent pulse mode respiratory device comprises sEMG module 5 that senses muscular activity in the thoracic region, an airflow sensor 4 that senses respiratory airflow, a microcontroller 6 with intelligent algorithm on-chip to sense instant of inhalation and exhalation, a solid state relay 7 and a solenoid valve 8 cut-off oxygen supply during exhalation and rest phases of the respiratory cycle. The device intelligently senses inhalation and exhalation merely using thoracic feedback (sEMG and airflow) from a few respiratory cycles which makes its automatic and manual intervention/ switching not essential. The intelligent algorithm used on the chip in the device is fast enough to efficiently make the solenoid valve ON/OFF. The device decreases the load and enhances the longevity of pulse-mode oxygen concentrators. The invention device is portable, wearable, cost-effective, has less weight and has a long-tested operating time of 9 hours on a single charge. |

| Startup Options: | The main advantages of the present invention are: a. Oxygen conservation of precious medical oxygen up to more than 50% on average could be achieved with the use of the developed device. b. Since the device senses inhalation/ exhalation and cuts off the oxygen supply to the subject in the exhalation phase, the device decreases the load and enhances the longevity of pulse mode oxygen concentrators. c. The developed device is portable (15 cm X15 cm X10 cm), cost-effective, weighs 254 grams, and has a long tested operating time of 9 hours on a single charge that makes it able to be classified as a wearable device. d. The device intelligently senses inhalation and exhalation merely using thoracic feedback (sEMG and airflow) from a few respiratory cycles which makes its automatic and manual intervention/ switching is not essential. e. The intelligent algorithm used on the chip in the device is fast enough to efficiently make the solenoid valve ON/OFF. f. The device works in near-real time wherein it can cut off the oxygen supply almost instantly whenever inferences related to the exhalation/rest phase of the respiratory cycle are sensed. |
