Problems solved by technology

Since the CPAP ventilator can only provide constant pressure, it cannot meet the requirement of increasing the pressure difference between inspiratory and expiratory pressure to improve blood gas when the patient is in deep sleep.

Embodiment 1

[0020] see figure 1 , the non-invasive ventilator that automatically selects the ventilation mode provided by the present invention includes a host 1, a tidal volume detection device (not shown) containing a tidal volume sensor 105, a long tube 2 and a mask 3, and the tidal volume sensor 105 is located in the long tube 2 , the host 1 adopts various positive airway pressure ventilation modes, such as CPAP, BIPAP, PAV and other ventilation modes 102, 103, 104, and automatically sets the most appropriate ventilation mode 102, 103, 104 through the automatic control module 101. mode, when the patient falls asleep, first set it to work in CPAP mode or near CPAP mode, and the automatic control module 101 detects the tidal volume of the patient according to the tidal volume detection device, and then sets it at Work in BIPAP mode, and set the patient's inspiratory pressure to 12cmH 2 O and expiratory pressure 6cmH 2 O, and adjust the inspiratory pressure of the ventilator to keep th...

Embodiment 2

[0023] see figure 2 The difference between this embodiment and the embodiment is that a human body physiological parameter detection device (not shown) including an EEG sensor 106 and an ECG sensor 107 connected to the automatic control module 101 is added; the EEG sensor 106 detects the patient's EEG signal, the ECG sensor 107 detects the patient's ECG signal, the automatic control module 101 analyzes the information detected by the EEG sensor 106 and the ECG sensor 107, and analyzes the patient's sleep according to the waveform of the EEG, the variation of the heart rate and the tidal volume state, when the patient enters deep sleep, change the ventilator working mode to enter BIPAP mode 103 or PAV mode 104, and when the patient enters light sleep, change the breathing mode to enter CPAP mode 102.

Abstract

The invention discloses a noninvasive ventilator capable of automatically selecting ventilation modes. The multiple air passage positive pressure ventilation modes are adopted and comprise the CPAP ventilation mode, the BIPAP ventilation mode and the PAV ventilation mode, at the initial time, the noninvasive ventilator is set in the CPAP ventilation mode or the approximate CPAP ventilation mode to work, an automatic control module is used for monitoring states of a patient, the noninvasive ventilator selectively enters the BIPAP ventilation mode or the PAV ventilation mode or other air passage positive pressure ventilation modes to work, and the pressure value is set. The approximate CPAP ventilation mode refers that the noninvasive ventilator enables the pressure difference of inspiration and expiration at the nose or the mouth to be maintained to be smaller than or equal to 5cm H2O in the breathing process of the patient. The noninvasive ventilator has the advantages of being capable of achieving automatic switching between the CPAP ventilation mode and other modes, being small in interference on the sleep structure of the patient, being capable of avoiding the phenomena of nocturnal desaturation and carbon dioxide retention of the patient, and improving the tolerance of the patient to the noninvasive ventilator.

Description

technical field [0001] The invention belongs to a non-invasive ventilator, in particular to a non-invasive ventilator for automatically selecting a ventilation mode. Background technique [0002] Non-invasive ventilators have been widely used in the treatment and rehabilitation of patients with chronic obstructive pulmonary disease (COPD), and a large number of cases have used non-invasive ventilators during sleep. On the one hand, the use of a ventilator can improve the patient's hypoxia and carbon dioxide retention problems, reduce the patient's work of breathing, and rest the patient's respiratory muscles; The pressure changes in the body will cause the patient's sleep quality to decline, and the patient will always feel as if someone is pushing the patient during sleep. Most of the non-invasive ventilators currently in use are bi-level positive airway pressure (BIPAP) mode non-invasive ventilators. When inhaling, the ventilator maintains a high pressure at the patient's...
