Pulmonary rehabilitation training system based on respiratory-muscle electrical signal feedback

Abstract

The invention discloses a pulmonary rehabilitation training system based on respiratory-muscle electrical signal feedback. The pulmonary rehabilitation training system comprises a controller, a magnetic directional valve, a flow sensor and an electrode connected with the controller through an amplifying circuit, wherein the magnetic directional valve and the flow sensor are connected with the controller. One way of the magnetic directional valve is communicated to an airway interface through the flow sensor. The other two ways of the magnetic directional valve are communicated with a pressureproportion regulating valve A and a pressure proportion regulating valve B, and the magnetic directional valve is switched and selected in the two ways. The pressure proportion regulating valve A is connected with a medical positive pressure air source. The pressure proportion regulating valve B is connected with a medical negative pressure air source. The pulmonary rehabilitation training systemis mainly used for a patient difficult in mechanical ventilation weaning, senses the tolerance of the patient in the pulmonary rehabilitation training process, intelligently adjusts the pressure and flow of breathing airflow in the rehabilitation training process, improves interpersonal coordination degree, avoids man-machine counteraction and lung injuries and promotes recuperation of autonomousrespiration ability.

Description

technical field [0001] The present invention relates to the technical field of medical devices, and more specifically relates to a pulmonary rehabilitation training system based on respiratory myoelectric signal feedback. Background technique [0002] Mechanical ventilation is an important means of clinical rescue and treatment of patients with respiratory failure, and is widely used in emergency and intensive care units of various clinical departments. However, long-term mechanical ventilation will cause patients to atrophy of respiratory muscles and respiratory function, leading to dependence on ventilator, difficulty in weaning, increased workload of medical staff, increased medical costs, and increased mortality. [0003] Existing ventilators do not have the function of pulmonary rehabilitation training. At present, in order to exercise the respiratory function of mechanically ventilated patients, doctors usually reduce the intensity of mechanical ventilation and increa...

Problems solved by technology

This method cannot refer to the actual tolerance of the patient, and it is easy to cause human-machine confrontation, resulting in lung injury, which is not conducive to the recovery of the patient.
