Description

结合疼痛评估调节输液参数的方法、系统、撤泵提示方法 技术领域
本发明涉及电子镇痛泵技术领域，尤其涉及一种结合疼痛评估调节输液参数的方法和系统，以及一种撤泵提示方法和具有撤泵提示功能的智能镇痛泵。
背景技术
目前针对可自动调节输液参数的电子输液泵系统，其原理是，通过记录和比对病人使用PCA(病人自控镇痛)的情况，达到预设条件后进行加量输注、减量输注或维持原参数输注。但是由于不同病人对于PCA理解和使用上的不一致，导致可能会出现以下情况：部分患者不轻易使用自控镇痛，系统达到预设减少输液参数条件后会自动减量输注，结果该病人在减档前略有疼痛尚可忍受，减量输注后出现疼痛加重的情况，不符合减量输注的目的；另有部分患者轻易使用自控镇痛，系统达到预设增加输液参数条件后会自动加量输注，结果该病人在加量前疼痛也不明显，加量输注后可能会出现副作用增加的情况，不符合加量输注的目的。
此外，针对目前临床上使用的参数非自动可调的电子输液泵，以及参数自动可调的个体化智能镇痛泵，都是等药物使用完了再撤掉镇痛泵，目前缺乏一个明确的指标来提示可以提前停止使用镇痛泵，从而减少不必要的止痛药物使用时间和减少药物使用量和副作用。

具体实施方式
下面将结合附图对本发明做详细的介绍。
实施例1
如图1所示，本实施例结合疼痛评估自动调节输液参数的方法，包括：输液系统触发自动加量或减量信号后，改变输注参数前进行疼痛评估，以判断本次输注参数的改变是否真实反映镇痛不足或镇痛过量，结合加量或减量信号以及疼痛评估结果进行加量输注、减量输注或维持原参数输注；具体为：
输液系统触发自动加量信号后，执行步骤S1；
S1：启动加量语音评估，询问病人目前疼痛情况；
S3：病人肯定应答，执行步骤S6；若病人否定应答，则执行步骤S5；
S5：不发出指令，维持原参数输注，并结束计时和本次评估；此是因为自动加量信号触发提示该病人目前可能存在镇痛不足，而经疼痛评估病人反馈此时并无明显疼痛感，此时若执行加量输注不具有准确性和可靠性，故不进行本次参数调整，维持原参数输注，待下次重新评估；
S6：进行加量输注，并结束计时和本次评估；此是因为自动加量信号触发提示该病人目前可能存在镇痛不足，同时经疼痛评估病人反馈此时存在疼痛感，两者一致，此时执行加量输注的准确性和可靠性得到进一步保障；
输液系统触发自动减量信号后，执行步骤S2；
S2：启动减量语音评估，询问病人目前疼痛情况；
S4：病人肯定应答，执行步骤S7；若病人否定应答，则执行步骤S5；
S7：进行减量输注，并结束计时和本次评估；此是因为自动减量信号触发提示该病人目前可能存在镇痛过度，同时经疼痛评估病人反馈此时不存在疼痛感，两者一致，此时执行减量输注的准确性和可靠性得到进一步保障；
S5：不发出指令，维持原参数输注，并结束计时和本次评估；此是因为自动减量信号触发提示该病人目前可能存在镇痛过度，而经疼痛评估病人反馈此时存在疼痛感，此时若执行 减量输注不具有准确性和可靠性，故不进行本次参数调整，维持原参数输注，待下次触发信号的出现重新评估。
作为优选，输液系统触发自动加量信号后，启动加量语音评估，具体为：
输液系统触发自动加量信号后，加量语音评估模块与病人语音对话，询问病人目前是否感觉疼痛，不能忍受，影响睡眠；

判断病人是否在应答周期内做出应答，若是，执行步骤S4；若否，执行步骤S5。
上述步骤中，应答周期内病人未作出应答，不发出指令，维持原参数输注，并结束计时和本次评估；意义在于：当输液系统触发自动加量或减量信号，提示可能存在镇痛不足或镇痛过度的情况，而病人在应答周期内未作出任何形式的回应，无法准确评估病人目前的疼痛情况，此时执行加量输注、减量输注不具有准确性和可靠性，故不进行本次参数调整，维持原参数输注，待下次触发信号的出现重新评估。
作为优选，所述步骤S3、S4中病人应答包含语音应答或按键应答。
作为优选，所述输液系统触发自动加量或减量信号后，改变输注参数前进行疼痛评估，以判断本次输注参数的改变是否真实反映镇痛不足或镇痛过量，结合加量或减量信号以及疼痛评估结果进行加量输注、减量输注或维持原参数输注，还可以为：

比对模块，加量语音评估模块启动时，收到病人肯定应答，执行处理模块2，进行加量输注，并结束计时和本次评估；否则，执行处理模块1，维持原参数输注，返回等待下一个触发信号(加量或减量)，并结束计时和本次评估；减量语音评估模块启动时，收到病人肯定应答，执行处理模块3，进行减量输注，并结束计时和本次评估；否则，执行处理模块1，维持原参数输注，返回等待下一个触发信号(加量或减量)，并结束计时和本次评估。

例如，预设2h内有效PCA激活信号达到4次，启动疼痛评估一次或者连续3h无有效PCA激活信号，启动疼痛评估一次，或者预设连续4h未进行疼痛评估，启动疼痛评估一次；设置4h内有效PCA激活信号高于3次/h为高频，小于等于3次/h为低频；开始运行后，第1个小时有效PCA激活信号达到4次，启动疼痛评估，疼痛评分4分，进行输注量调整；之后连续3h无有效PCA激活信号，启动疼痛评估，疼痛评分2分，维持原参数运行，再之后连续4个小时均未达到条件进行疼痛评估，则通过预设连续4h未进行疼痛评估，启动疼痛评估一次，结合疼痛评估及有效PCA激活信号次数来决定是否调整输液参数，以避免长时间无 评估。
如图8所示，本发明一种用于镇痛泵的撤泵提示方法，包括以下步骤：
步骤A：判断当前持续输注量是否低于预设最低有效持续输注量(本例最低有效持续输注量为0)，若是，执行步骤B，若否，执行步骤A。实际应用中，持续输注量可以通过医生直接设置为0或者通过自动参数可调的技术，患者因为疼痛改善持续输注量慢慢减为0；预设自动可调范围下限不为0的，可默认增设一档持续量为0，达到下限且持续设定时间内无镇痛激活信号，则将持续输注量先降为0再执行步骤A。镇痛激活信号是指镇痛泵的处理模块，或与镇痛泵电性连接的其他外接设置的处理模块采样到的镇痛激活信号。
步骤B：开始计时并执行步骤C。
步骤C：判断计时时间是否超出预设计时周期，若是，执行步骤E；若否，执行步骤D。
步骤D：是否有镇痛激活信号，若是，计时时间清零并执行步骤A，若否，执行步骤C；
步骤E：进行疼痛评估，是否存在疼痛，若否，执行步骤F，若是，计时时间清零并执行步骤A；
步骤F：发出撤泵提示信号并结束计时，表示本次周期结束。
如此，持续量减少到0，持续预设时间未进行单次输注且经过评估当下无疼痛，说明病人此时停止使用止痛药也已经不痛，本方法即发出撤泵提示信号，该提示信号可通过镇痛泵的本地光学提示模块进行提示，优选的，可采用绿色光源，也可通过网络模块远程发送至上位机进行提示，或通过通信模块发送至医护人员手机上进行提示，让医护人员及时了解到目前病人已达到可以停止使用镇痛泵的状态。
作为优选，所述疼痛评估除采取是否存在疼痛这种定性评估外，亦可进行定量评估，即采用疼痛评分法，疼痛评分为0分，则视为不存在疼痛；疼痛评分为1分或以上，则视为存在疼痛。所述疼痛评分法包括视觉模拟评分法、数字评分法、主诉疼痛程度分级评分法、口述疼痛程度分级评分法。
作为优选，所述定性评估具体为：语音询问病人是否存在疼痛，病人通过语音或操作按键应答，若是，视为存在疼痛，若否，视为不存在疼痛。
