Embodiment Construction

[0035] Embodiments of the present invention are described below with reference to the drawings, in which like parts are denoted by like reference numerals. In the case of no conflict, the following embodiments and the technical features in the embodiments can be combined with each other.

[0036] Such as figure 2 As shown, the automatic expectoration method of the present invention comprises:

[0037] S1, sequentially provide positive pressure phase for inflation and negative pressure phase for exhaust.

[0038] S2, in the positive pressure phase, use the positive pressure inflation phase end sensitivity to trigger switching to the negative pressure phase. The positive pressure inflation phase end sensitivity is related to the patient's cough effort. Specifically, when it is detected that the sensitivity at the end of the positive-pressure inflation phase reaches the set first threshold, it switches to the negative-pressure phase. Optionally, the end time of the positive ...

Abstract

The invention relates to a synchronous automatic expectoration method. The method comprises the steps that S1, in sequence, a positive pressure phase is provided for air inflation, and a negative pressure phase is provided for air discharging; S2, in the positive pressure phase, a positive pressure air inflation phase ending sensitivity is used for triggering a switch to the negative pressure phase, and the positive pressure air inflation phase ending sensitivity is related to a cough force condition of a patient; S3, in the negative pressure phase, a negative pressure air discharging phase ending sensitivity is used for triggering a switch to the negative pressure phase or a cough intermittence phase, and the negative pressure air discharging phase ending sensitivity is related to the cough force condition of the patient; S4, the cough intermittence phase is provided and located between the negative pressure air discharging phase this time and the positive pressure air inflation phasenext time, and positive pressure supporting ventilation is provided at the cough intermittence phase multiple times. The invention further provides a synchronous automatic expectoration system. By applying the method and system, the treatment effect of sputum clear-away on the trachea when a patient wears the expectoration system can be improved.

Description

technical field [0001] The present invention relates to a sputum expectoration machine, and more specifically, to a mechanical inflation and exhaust method and system for synchronous automatic expectoration. Background technique [0002] Cough is a physiological mechanism for normal people to clear respiratory airway secretions. However, for some patients with cough dysfunction diseases, such as patients with neuromuscular diseases with reduced cough force and patients with mechanical ventilation intubation, it becomes very necessary to use some kind of external force to clear airway secretions. [0003] A mechanical inflation-exhaust (MI-E) device, commonly known as an expectorator, is a well-known device used to assist patients with an ineffective cough to clear their airways of noxious secretions. This device simulates the coughing physiological mechanism of normal people, and controls the pipeline connected to the patient (mask connection end, mouthpiece connection end,...
