[0002] Exhalation trigger is a term in respiratory medicine, which is common in ventilators and anesthesia machines. It is defined as sensing the patient's exhalation, and then the ventilator or anesthesia machine makes a corresponding stop of gas supply according to the relevant trigger command to assist the patient's breathing. The existing practice is to judge the patient's exhalation action according to the set exhalation trigger (or stop level) threshold, that is, when the patient's inspiratory flow rate drops to the set peak flow rate percentage value, it is considered that the patient begins to exhale. That is, whether the patient is exhaling is judged by whether the current real-time flow rate meets the set threshold. However, since the opening of the pneumatic valve requires a certain response time, it may cause a delay in the exhalation trigger and fail to achieve the ideal set conversion percentage.

[0042] In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. The embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0043] See also Figure 1 , Figure 1 Flow chart of an embodiment of the method for solving the exhalation trigger delay provided by the present invention. Figure 1 As shown, the method comprises the following steps:

[0044] S100, obtaining the current call transfer point flow rate;

[0045] S200, comparing the flow rate at the call transfer point with the ideal flow rate to determine whether the call transfer point is abnormal;

[0046] S300: If an abnormality occurs at the call transfer point, revise the flow rate of the call transfer point according to the feedback adjustment mechanism and adjust the call transfer point.

[0047] In this embodiment, the flow rate of the current transfer point of the medical device is obtained, and the flow rate of the current transfer point is compared with the preset ideal flow rate to determine whether an abnormality occurs at the current transfer point. According to the type of abnormality, the flow rate of the transfer point is revised through the feedback adjustment mechanism to adjust the transfer point to the position of the ideal transfer point, wherein the abnormality type includes early transfer and delayed transfer. Through periodic feedback adjustment, the point where the pneumatic valve actually starts to transfer after the response time reaches the ideal peak flow rate percentage, which can effectively solve the exhalation trigger delay caused by the valve opening response time.

[0048] In one embodiment, before step S100, the method further includes:

[0049] Identify the set point for the exhalation trigger;

[0050] Calculate and set the call transfer percentage according to the set value and the quantitative threshold;

[0051] The set call transfer percentage is used as the current cycle trigger threshold.

[0052] In this embodiment, the exhalation trigger set value is identified, and a quantitative threshold FixedThresh is first added on the basis of the set value to determine the turn-to-call percentage SetTurnPercent when the exhalation is triggered, and SetTurnPercent = SetTurnPercent + FixedThresh is used as the current cycle trigger threshold, wherein the current cycle trigger threshold is used to control the time to open the pneumatic valve in the current cycle. The turn-to-call point is advanced according to the increased quantitative threshold, and the time to open the pneumatic valve will inevitably be advanced at this time, and then through periodic feedback adjustment, the point where the pneumatic valve actually starts to turn to the call after the response time reaches the ideal peak flow rate percentage, which can effectively solve the exhalation trigger delay caused by the valve opening response time.

[0053] In one embodiment, the step S200 includes:

[0054] If the flow rate at the transfer point reaches the ideal flow rate, the transfer point is normal;

[0055] If the flow rate at the transfer point does not reach and / or exceeds the ideal flow rate, the transfer point is abnormal.

[0056] In this embodiment, the actual flow rate of the call transfer point is obtained and compared with the ideal flow rate. When the flow rate of the call transfer point reaches the ideal flow rate, that is, it reaches the ideal call transfer point, and no abnormality occurs, it is a normal call transfer point state, and the current quantitative threshold is maintained. When the flow rate of the call transfer point does not reach the ideal flow rate, that is, the call transfer point does not reach the set ideal call transfer point, then the call transfer point is abnormal. When the flow rate of the call transfer point exceeds the ideal flow rate, that is, the call transfer point exceeds the set ideal call transfer point, then the call transfer point is abnormal. Accurately detect whether the call transfer point is abnormal, and quickly respond to solve the abnormal situation.

[0057] In one embodiment, the abnormal types include early call forwarding and delayed call forwarding, specifically including:

[0058] If the flow rate of the call transfer point does not reach the ideal flow rate, confirming that the call transfer point transfers the call in advance;

[0059] If the flow rate at the call transfer point exceeds the ideal flow rate, it is determined that the call transfer point is delayed in call transfer.

[0060] In this embodiment, if the flow rate at the transfer point does not reach the ideal flow rate, and the transfer point does not reach the set flow rate target percentage, that is, the time for the pneumatic valve to open is advanced, then it is confirmed that the transfer point is transferred in advance; if the flow rate at the transfer point exceeds the ideal flow rate, and the transfer point exceeds the set flow rate target percentage, that is, the time for the pneumatic valve to open is delayed, then it is confirmed that the transfer point is transferred in delay.

[0061] In one embodiment, the step S300 includes:

[0062] Obtaining the transition point flow rate and the maximum inspiratory flow rate;

[0063] Calculate the difference of the transfer point according to the transfer point flow rate, the maximum inspiratory flow rate and the set transfer percentage;

[0064] The quantitative threshold is adjusted according to the difference to revise the call transfer point.

[0065] In this embodiment, the actual turn flow rate ActualTurnFlow and the maximum inspiratory flow rate MaxInspFlow are obtained, and the difference Error is calculated by the formula according to the turn flow rate, the inspiratory flow rate and the set turn percentage.

[0066]

[0067] The quantitative threshold when the call transfer point is abnormal is adjusted according to the difference, and the call transfer point is adjusted to a normal state to solve the problem of premature call transfer or delayed call transfer at the call transfer point.

[0068] In one embodiment, the feedback adjustment mechanism includes:

[0069] If the call transfer point transfers the call in advance, reducing the quantitative threshold according to the difference;

[0070] If the call transfer point transfers the call with a delay, the quantitative threshold is increased according to the difference.

[0071] In this embodiment, if the transfer point is transferred ahead of time, that is, the transfer point has not reached the set peak flow rate target percentage at this time, it is necessary to adjust according to the difference, reduce the quantitative threshold and make a certain amplitude limit to delay the opening time of the pneumatic valve. If the transfer point is transferred behind time, that is, the transfer point has exceeded the set peak flow rate target percentage at this time, it is necessary to adjust according to the difference, increase the quantitative threshold and make a certain amplitude limit to advance the opening time of the pneumatic valve.

[0072] Another embodiment of the present invention also provides an application flow chart of a method for solving the exhalation trigger delay, such as Figure 2 As shown, the following steps are included:

[0073] (1) Identify the exhalation trigger setting value;

[0074] (2) Increase the quantitative threshold;

[0075] (3) Determine whether the call transfer point in the current cycle is ahead of schedule, delayed, or normal;

[0076] (4) The call transfer point is normal and the current quantitative threshold is maintained;

[0077] (5) Call transfer points transfer calls in advance to reduce the quantitative threshold;

[0078] (6) The call transfer point lags behind the call transfer point and increases the quantitative threshold;

[0079] (7) Adjust the call transfer point to the ideal call transfer point.

[0080] In this embodiment, the exhalation trigger setting value is first identified, and a quantitative threshold is added on the basis of the setting value to advance the transfer point, obtain the transfer point flow rate, and judge whether the transfer point of the current cycle is advanced, delayed, or normal. If the transfer point is normal, the current quantitative threshold is protected. If the transfer point is transferred in advance, the quantitative threshold is reduced. If the transfer point is delayed, the quantitative transfer is increased. The transfer point is controlled to reach the ideal transfer point according to the feedback adjustment mechanism, which effectively solves the problem of exhalation trigger delay caused by the valve opening response time.
