Problems solved by technology

However, the existing technologies and means cannot constantly monitor the gas pressure and flow rate changes in the patient's airway at all levels, resulting in the fundamental deficiency of the current extubation indications. Use only indirect indicators to determine the timing of extubation

Embodiment Construction

[0047] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0048] 1. Establishment of pressure control model

[0049] Such as figure 2 As shown, in adult patients, 13cm H 2 The positive pressure of O is used for ventilation, and the respiratory rate is 10bpm. When the ventilator sends the positive pressure of gas into the main airway, the airway pressure rises rapidly to the peak pressure of 16cm H 2 O, and maintain the plateau peak pressure until the positive pressure of the ventilator ends, and then the airway pressure drops rapidly to 0. The intratracheal pressure gradually rises to the highest at the peak platform, and gradually decreases to 0 after the end of the positive pressure of the ventilator. The time required for the rise and fall is equal, and the peak pressure has no platform.

[0050] During mechanical ventilation, in the pressure control mode, the patient’s main airway parameters and the ga...

Abstract

The invention relates to the field of anesthesia breathing and specifically relates to a respirator mode control system. The system comprises an intra-pulmonary pressure measurement catheter, a trachea cannula, a multi-mode respirator and a control system. The intra-pulmonary pressure measurement catheter is used for measuring the intratracheal pressure and ventilation flow speed in a bronchus ofa pulmonary segment, and transmitting the measured data to the control system in real time. The trachea cannula is provided with a pressure sensor, and the pressure sensor is used for measuring the pressure of an airway and transmitting the measured data to the control system in real time. The multi-mode respirator supports the respiration of a patient, and the control system controls the switching of the working mode of the multi-mode respirator. The system provided by the invention can remind the switching of the working mode, achieves the smooth transition of respiration, shortens the machine control time, reduces the man-machine counteraction, achieves the protection of a lung, can objectively and clearly remind the signs of tube drawing, achieves the muscle-relaxing monitoring at first, and is independent of alarm monitoring respiration control.

Description

technical field [0001] The invention relates to the field of anesthesia breathing, in particular to a ventilator mode control system. Background technique [0002] After the induction of general anesthesia is completed, the patient's spontaneous breathing disappears, and the ventilator is required to provide respiratory support, that is, the anesthesiologist inserts a catheter into the patient's main airway to deliver a certain pressure or volume of gas into the main airway, and the continuously injected gas passes through the main airway. Airway-main bronchus-pulmonary bronchi-pulmonary segmental bronchi-terminal bronchioles, and finally reach the alveoli to complete lung ventilation. When the positive pressure of the ventilator disappears, the gas will be discharged by the lung's own resilience. However, the recovery of spontaneous breathing is a reverse process. The respiratory muscles do their own work, and the gas is squeezed from the alveoli and terminal bronchioles in...
