输液泵及其输液管路上阻塞报警方法和装置 Infusion infusion pumps and pipeline blockage warning method and apparatus

技术领域 FIELD

[0001] 本申请涉及一种医疗器械,具体涉及一种输液栗及其输液管路上阻塞报警方法和 [0001] The present application relates to a medical instrument, particularly to an infusion and transfusion Li pipeline obstruction warning method and

目.ο Head .ο

背景技术 Background technique

[0002] 医用输液栗是将药液输入到患者体内的设备,安全性的要求很高。 [0002] Li is a medical liquid infusion into the patient input device, a high security requirements. 如果在输液过程中由于流入输液栗的上游药液发生阻塞而断流,又没有相应的操作,那么输入病人体内的药量会减少,对急需治疗的重症患者来说可能会产生生命危险。 If the inflow of liquid due to upstream obstruction infusion Li occurs during the infusion interrupter, and no corresponding operation, the input dose reduction the patient will, in urgent need of treatment for critically ill patients who may produce life-threatening. 所以上游发生阻塞时,输液栗就需要有相应的检测机构及相应的执行措施。 Therefore, when jamming occurs upstream, Li infusion requires a corresponding detection means and the corresponding implementation measures.

[0003] 请参见公开号为CN 102114279 Α的中国专利,其公开了一种输液栗,通过在输液栗的上游设置压力传感器,当出现上游阻塞时,输液栗就会启动报警装置,并伴有声光报警和进行停止输液的操作。 [0003] See Publication No. CN 102114279 Α Chinese patent, which discloses a infusion Li, by a pressure sensor disposed upstream of the infusion chestnut, when there is an upstream occlusion, Li will start the infusion alarm device, and with sound and light alarm and stopping the operation of the infusion. 从而避免因输液管上游的阻塞而延误患者治疗的问题,提高了输液的安全性。 In order to avoid problems caused by obstruction of the infusion tube upstream of the delayed treatment of patients, improve the safety of infusion.

[0004] 然而,对于传统的输液栗,都是采用压力传感器对输液管路压力进行实时监测。 [0004] However, traditional infusion Li, are employed infusion line pressure pressure sensor in real time. 首先在输液栗内部设置一个压力报警阈值,输液栗启动后,压力传感器持续对输液管路进行监测,在任意时刻,输液栗将检测到的实时压力值传递给CPU,CPU比较实时压力值与压力报警阈值的大小,如果实时压力值小于压力报警阈值,输液栗正常工作,否则,立即触发报目ο First, set a pressure alarm thresholds within the infusion Li, after infusion Li started, the pressure sensor duration of infusion line monitoring, at any time, the infusion Li of the detected real-time pressure value is passed to the CPU, comparing the real-time pressure value and the pressure CPU the size of the alarm threshold, if the real-time pressure alarm threshold value is less than the pressure, infusion chestnut normal operation, otherwise, immediately activates an eye ο

[0005]由于输液管在正常使用的过程中,随着时间的推移,管路的应力会不断的释放,使得管路对压力传感器的应力不断减小,因此,对于这种报警方式,常常会带来下面两个问题:(1)报警时刻的阻塞压力范围无法达到目标值。 [0005] Since the infusion tube during normal use, over time, the stress will continue to release the pipe, so that the stress on the pressure sensor conduit decreases continuously, and therefore, for this alarm mode, often bring the following two questions: (1) blocking the alarm time pressure range of the target can not be achieved. (2)正常使用过程中,会因干扰而误报上阻塞压力报警,影响客户使用体验。 (2) during normal use, due to interference and false alarms on blocking pressure, affect the customer experience. 同时,对于不同品牌的管路,其阻塞的报警压力值是不一样的,因此单纯通过检测压力值,在使用不同品牌时存在误报的风险。 Meanwhile, different brands of tubing, occlusion alarm pressure value which is not the same, so simply by detecting the pressure value present when the risk of false positives using different brands.

[0006] 因此,现有技术中,上阻塞报警的准确性依旧有待提高。 [0006] Thus, the prior art, the accuracy of the blockage alarm still needs to be improved.

[0033] 阻塞识别区判断模块202用于判断该数据是否进入阻塞识别区;该阻塞识别区表示输液栗的输液管路处于上端阻塞状态。 [0033] blocking recognition region determination module 202 determines whether the data entered for identification area obstruction; field indicates the identifying occlusion of the infusion line Li infusion blocked at the upper end.

[0035] 下面结合上阻塞报警方法,对上阻塞报警装置作进一步说明。 [0035] The following alarm blocking binding method, the occlusion alarm will be further described.

[0036] 请参考图3,上阻塞报警方法包括下面步骤: [0036] Please refer to FIG. 3, the method comprising the steps of blocking the alarm:

[0037] 步骤1.1:输液栗运行后,数据获取模块201获取输液栗运行时上压力传感器采集的数据,该数据通常为上压力传感器采集的压力值。 [0037] Step 1.1: Li after the infusion operation, a data acquisition module 201 acquires data from the pressure sensor collected runtime Li infusion, the pressure sensor data is typically acquired pressure value.

[0038] 步骤1.2:运行模块判断模块204判断输液栗的运行模式,当判断为高速运行模式时,执行高流速算法处理步骤,即转到步骤1.3,基于上压力传感器采集的数据和设定的报警阈值对上阻塞进行报警监测;当判断为低速运行模式时,执行低流速算法处理步骤,即转到步骤1.4,基于上压力传感器采集的数据和设定的报警阈值对上阻塞进行报警监测。 [0038] Step 1.2: Run Module operation mode determination module 204 determines the infusion chestnut, when it is determined that high-speed operation mode, perform high flow rate arithmetic processing step, i.e., go to step 1.3, based on the data collected by the sensor and the pressure set alarm threshold of the occlusion alarm monitoring; when it is determined that the low-speed operation mode, performs a low flow rate arithmetic processing step, i.e., go to step 1.4, the alarm monitoring of the block on the alarm threshold and setting on the pressure sensor collected.

[0039] 具体的,运行模块判断模块204在确定输液栗的运行模式时,可以获取用户输入的流速,以判断该流速属于高流速还是低流速。 [0039] Specifically, the operation of the module when determining module 204 determines the operating mode of the infusion Li, flow rate input by the user can be acquired, to determine whether the flow rate belongs to the high or low flow velocity. 例如,定义大于800ml/h的流速为高流速,则运行模块判断模块204判断到用户输入的流速大于800ml/h时,判断为高速运行模式,否贝1J,判断为低速运行模式。 For example, the definition of greater than 800ml / h flow rate of high velocity, run module determines module 204 determines a user to input a flow rate greater than 800ml / h, high-speed operation mode is determined, whether the shellfish 1J, low-speed operation mode is determined. 当然,在其他实施例中,高、低流速的界限值可以根据实际情况选择,或者也可以根据实际情况采用其他的判断方式。 Of course, in other embodiments, high, low flow rate limit value may be selected according to the actual situation, or may also use other ways of determining the actual situation.

[0040] 步骤1.3:处理模块203执行高流速算法处理步骤,基于上压力传感器采集的数据和设定的报警阈值对上阻塞进行报警监测。 [0040] Step 1.3: The processing module 203 performs arithmetic processing step of high flow rates, blocking the alarm monitoring based on the alarm threshold and setting on the pressure sensor collected. 优选的,本实施例中,处理模块203根据两个阻塞识别区内上压力传感器采集的数据的变化情况,基于上压力传感器采集的数据和设定的报警阈值对上阻塞进行报警监测。 Preferably, in this embodiment, the processing module 203 in accordance with changes in the pressure area sensor two blocking recognition of data collected, based on the data and alarm threshold set on the pressure sensor collected by the monitoring alarm blocking.

[0041] 步骤1.4:处理模块203执行低流速算法处理步骤,基于上压力传感器采集的数据和设定的报警阈值对上阻塞进行报警监测。 [0041] Step 1.4: The processing module 203 performs arithmetic processing step of low flow, clogging alarm monitoring based on the pressure data collected by the sensor and the set alarm threshold. 优选的,本实施例中,处理模块203根据所有阻塞识别区内上压力传感器采集的数据的变化情况,基于上压力传感器采集的数据和设定的报警阈值对上阻塞进行报警监测。 Preferably, in this embodiment, the processing module 203 in accordance with changes in the pressure sensor of the identification area blocking all data collected, based on the data and alarm threshold set on the pressure sensor collected by the monitoring alarm blocking.

[0042]目前,输液栗在高流速下运行时,会因高流速对管路产生应力,导致压力传感器采集的数据波动。 [0042] Currently, Li infusion when operating at high flow rates, due to the high flow conduit stress, resulting in pressure fluctuations of data collected by sensors. 对于低流速,则不会产生这种情况,低流速采集的数据是平稳的。 For low flow rates, does not generate such a case, data acquisition is low flow steady. 因此,在上阻塞报警过程中,容易导致在高流速情况下,误报上阻塞。 Thus, in the alarm blocking process, easily lead to the case at high flow rates, blocking the false positives. 并且,对于低流速情况下的阻塞状态,尤其是在全挤压模式下,输液管路形变量非常小,几乎等于管路受挤压原有应力的变化量,也就是说低流速阻塞的状态跟正常输液状态几乎无差异,所以要检测低流速的上阻塞状态是非常困难。 And for the blocked state at low flow rates, especially in the full-press mode, infusion line deformation is very small, almost equal to the original line by pressing the change amount of stress, i.e. low flow blocking state infusion with normal state is almost no difference, so it is very difficult to detect the blocked low flow rate. 为了保证报警的准确性,现有技术的报警方式必须分别考虑高流速和低流速情况,导致其能够适用的流速范围较窄,报警不够准确。 To ensure the accuracy of the alarm, the prior art must be considered separately alarm mode high flow rate and low flow rates, resulting in a narrower range of flow rates can be applied, the alarm is not accurate enough.

[0043] 所以,本实施例中,通过步骤1.2,先判断输液栗的运行模式,当判断为高速运行模式时,执行高流速算法处理步骤,并基于上压力传感器采集的数据和设定的报警阈值对上阻塞进行报警监测;当判断为低速运行模式时,执行低流速算法处理步骤,并基于上压力传感器采集的数据和设定的报警阈值对上阻塞进行报警监测。 [0043] Therefore, in this embodiment, step 1.2, the operation mode is determined to infusion chestnut, when it is determined that high-speed operation mode, perform high flow rate arithmetic processing step, based on the pressure sensor to collect alarm data set and threshold for monitoring the occlusion alarm; when it is determined that the low-speed operation mode, performs a low flow rate arithmetic processing step, and the blocking of the alarm monitoring based on the alarm threshold data collected by the sensor and the pressure setting. 即将高速运行和低速运行模式分别对待,而不是进行相同的算法处理。 Upcoming high-speed operation and low speed operation mode treated separately rather than deal with the same algorithm. 这样便为高流速算法处理步骤更好地适应高速运行模式,低流速算法处理步骤更好地适应低速运行模式提供了基础,通过分别根据这两种运行模式的特点设计相应上阻塞报警算法,从而解决同一报警算法处理方式为兼顾高流速和低流速情况而导致其能够解决适用的流速范围过窄的问题,实现了上阻塞报警的宽流速检测范围,能够较好地适用高流速和低流速运行情况,使得报警更加准确。 This will better accommodate high-speed operation mode to the arithmetic processing step of high flow rate, low flow rate step processing algorithm to better adapt to the low-speed mode of operation provides the basis, respectively, by the characteristics of these two operating modes corresponding to the alarm blocking algorithm designed to alarm processing algorithm to solve the same manner as both high flow and low flow rates which can solve the problem caused by narrow flow rate range applied to achieve occlusion alarm on a wide range of flow velocity detector, suitably applicable high flow rate and low flow rate operation situation, making the alarm more accurate.

[0044] 当然,在其他实施例中,也可以不针对高流速和低流速运行模式进行不同的算法处理,而只是针对阻塞识别区内的数据变化情况来进行上阻塞报警监测。 [0044] Of course, in other embodiments, may not be a different algorithm for processing a high flow rate and low flow rate operation mode, but only for identifying the data change area blocked by blocking the alarm situation to the monitor.

[0045] 请参考图4,本实施例中,上述步骤1.3具体包括: [0045] Please refer to FIG 4, in this embodiment, the step 1.3 includes:

[0046] 步骤2.1:阻塞识别区判断模块202判断上压力传感器采集的数据是否进入第一阻塞识别区,如果否,则继续检测;如果是,则转到步骤2.2。 [0046] Step 2.1: blocking recognition section determines whether data acquisition module 202 determines the pressure sensor into the first blocking identification area, if not, continues to detect; if yes, go to step 2.2.

[0047] 首先,需要说明的是,上阻塞压力检测过程中,当输液管路处于上端阻塞,如关闭止液夹、关闭调速器、管路受到挤压、滤网被堵塞等阻塞状态下,在栗片的运动时,上压力传感器会采集到数据的变化。 [0047] First, it is noted that the occlusion pressure detecting process, when the upper end of the infusion line is blocked, such as the liquid stopper closing the clip, close governor, squeezed tubing, filters are blocked by a blocking state when the motion Li sheet, the pressure sensor will change the data collected. 通过对数据分析可以得知在某个区间内,上压力传感器的数据是有别于正常输液模式的,这个区间称作为阻塞识别区。 By analyzing the data can be known in a certain range, the data is different from the normal pressure sensor the infusion mode, this range is referred to as blocking recognition region. 第一阻塞识别区是输液栗在运行的过程中,当处于上阻塞状态下,栗片第一圈运动导致上阻塞压力传感器受力变化的区间,第二阻塞识别区是指栗片在第二圈运动检测到的区间,依此类推。 First blocking region is identified in the infusion Li during running, when in the blocked state, the first ring plate movement causes Li occlusion pressure on the force sensor by varying section, a second blocking means Li identification area a second sheet circle motion is detected in the zone, and so on. 因此,输液栗运行过程中,当处于上阻塞状态时,在栗片不断运动的过程中会产生多个阻塞识别区。 Thus, during infusion Li operation, when in the blocked state, in constant motion during Li sheet will produce a plurality of blocking regions identified.

[0048] 另外,进入阻塞识别区(阻塞状态)并不代表可以触发报警阻塞,因为通常厂家对输液栗的上阻塞是有宣称规格的,需要达到一定目标值(报警阈值)才可以触发上阻塞报目ο [0048] Further, enters the blocking area identification (blocked state) does not represent obstruction alarm can be triggered, because usually the manufacturer of infusion is declared Li blocking specifications required to achieve a certain target value (alarm threshold) in order to trigger the blocking News head ο

[0049] 具体的,可以通过对上压力传感器的数据进行斜率分析来判断是否进入阻塞识别区。 [0049] Specifically, the slope may be analyzed to determine whether the data entered for identification area blocked on the pressure sensor. 斜率分析的算法如下:实时采集栗端上压力传感器的压力值,根据时刻要求,存入指定数组,对数组前后的数据进行对比,根据设定的算法参数判断数值及持续时间是否达到算法设定值,若达到则认为进入阻塞识别区。 Analysis of the slope of the algorithm is as follows: real-time acquisition Li pressure on the end of the pressure sensor, based on the time required, into the specified array, the array of data before and after comparison, the value is determined according to the algorithm and the parameter set duration reaches a preset algorithm value, if it is considered to reach into the blocking identification zone. 当然,在其他实施例中,也可以根据实际情况采用其他方式来判断是否进入阻塞识别区。 Of course, in other embodiments, other means may be employed according to the actual situation to determine whether to enter the blocking area identification.

[0050] 步骤2.2:当阻塞识别区判断模块202判断到进入第一阻塞识别区时,处理模块203记录位于第一阻塞识别区起点的数据,作为第一初始数据。 [0050] Step 2.2: determining when the blocking zone identification module 202 determines to enter the first blocking region recognition processing module 203 in the data recording start point of the first blocking identification area, as the first initial data.

[0051] 步骤2.3:当处于阻塞识别区期间,处理模块203实时获取上压力传感器采集的数据,计算该实时数据与第一初始数据的差值,对该差值进行处理,得到处理后的比较值。 [0051] Step 2.3: when the recognition region is blocked during the processing module 203 acquires the real-time data collected by the pressure sensors, calculates the difference between the real-time data and the first initial data, processing the difference value, comparing treated to give value. 具体的,对该差值进行处理,可以是通过一具体的换算公式,将该差值换算成用于与报警阈值进行比较的比较值。 Specifically, the difference processing can be through a specific conversion formula, in terms of the difference between the comparison value for comparison with the alarm threshold.

[0052] 步骤2.4:处理模块203判断该比较值是否小于报警阈值,如果是,则转到步骤 [0052] Step 2.4: the processing module 203 determines whether the comparison value is less than the alarm threshold, if yes, go to step

2.5 ;如果否,则触发上阻塞报警。 2.5; if not, an alarm is triggered on the obstruction.

[0053] 步骤2.5:处理模块203判断上压力传感器采集的数据是否离开第一阻塞识别区,如果否,则转到步骤2.3 ;如果是,则执行步骤2.6。 [0053] Step 2.5: the processing module 203 determines whether the data collected by the pressure sensor away from the first blocking zone identification, and if not, go to step 2.3; if yes, step 2.6.

[0054] 步骤2.6:在阻塞识别区判断模块202判断到上压力传感器采集的数据离开第一阻塞识别区时,处理模块203记录此时上压力传感器采集的位于第一阻塞识别区终点的数据与第一初始数据的差值,作为第一差值。 [0054] Step 2.6: identifying when a blocking area determination module 202 determines the data collected by the pressure sensor away from the first blocking region recognition processing module 203 in a data identification area recording at this time the end of the first pressure sensor to collect the occlusion and a first difference between the initial data, a first difference.

[0055] 步骤2.7:阻塞识别区判断模块202判断上压力传感器采集的数据是否进入下一个阻塞识别区,如果是,则转到步骤2.8 ;如果否,则继续检测。 [0055] Step 2.7: blocking recognition section 202 determines whether or not the data is determined on the pressure sensor module into the next blocking acquired identification area, if yes, go to step 2.8; if no, continue detection.

[0056] 步骤2.8:在阻塞识别区判断模块202判断到上压力传感器采集的数据进入下一个阻塞识别区时,处理模块203记录此时的第二初始数据。 [0056] Step 2.8: identifying a blocking area when the determining module 202 determines the pressure sensor to collect data entry identifying a blocking zone, a second processing module 203 records initial data at this time.

[0057] 步骤2.9:当处于阻塞识别区期间,处理模块203实时获取上压力传感器采集的数据,计算该实时数据与第二初始数据的差值。 [0057] Step 2.9: when the recognition region is blocked during the processing module 203 acquires the real-time data collected by the pressure sensors, calculates the difference between the original data and the second real-time data.

[0058] 步骤2.10:处理模块203将该差值与第一差值相加,得到第一累计值,对第一累计值进行处理,得到处理后的比较值。 [0058] Step 2.10: The processing module 203 and the first difference value by adding the difference value to obtain a first integrated value, the integrated value of the first, to give the comparison value after the treatment. 具体的,对第一累计值进行处理,可以是通过一具体的换算公式,将该第一累计值换算成用于与报警阈值进行比较的比较值。 Specifically, a first integrated value of the processing may be by a particular conversion formula, the first integrated value is converted into the comparison value for comparison with the alarm threshold.

[0059] 步骤2.11:处理模块203判断该比较值是否小于报警阈值,如果是,则转到步骤 [0059] Step 2.11: the processing module 203 determines whether the comparison value is less than the alarm threshold, if yes, go to step

2.12 ;如果否,则触发上阻塞报警。 2.12; if not, an alarm is triggered on the obstruction.

[0060] 步骤2.12:阻塞识别区判断模块202判断上压力传感器采集的数据是否离开当前阻塞识别区,如果是,则继续检测下一个阻塞识别区;如果否,则转到步骤2.9。 [0060] Step 2.12: blocking recognition section determines whether data acquisition module 202 determines the pressure sensor away from the current blocking recognition region, and if so, proceed to the next detection of a blockage identification area; if no, go to step 2.9.

[0061]目前,专用耗材输液栗只能使用专用耗材的,即不同厂家或型号的输液栗只能使用专用的耗材,专用耗材的弹性大小、应力变化都是预先知晓的,因此在设计报警算法的时候,可以不考虑其他管路的属性,只针对专用耗材的属性进行算法开发。 [0061] Currently, Li supplies for infusion supplies only the special, i.e., different manufacturers or models infusion Li only the special consumables, the supplies for the size of the elastic, stress variations are known in advance, so the design alarming algorithm It can not be considered property of another line, only for algorithm development for supplies of property. 然而,对于开放耗材输液栗,在其使用过程中,用户会使用其他开放耗材,对于其他开放耗材,其弹性大小、应力变化皆不同,因此其往往不符合厂家宣称的上阻塞压强,则预先设计的上阻塞报警算法无法适用开放耗材。 However, for open supplies infusion Li, during its use, a user may use other open supplies, for other open supplies its flexible size, stress changes are different, so it is often incompatible with manufacturers claim that the blocking pressure is predesigned the alarm algorithm can not be applied on open blocked supplies.

[0062] 为解决该技术问题,优选的,本实施例中,上阻塞报警装置105还包括报警阈值调整模块205,用于在安装好输液管路,关闭输液栗门的预设时间段后,获取上压力传感器采集的数据,并根据该数据调整报警阈值,其中,上压力传感器采集的该数据反应了输液管路的软硬程度。 [0062] In order to solve this technical problem, it is preferable, in this embodiment, the occlusion device 105 further includes an alarm warning threshold adjustment module 205 for the infusion line installed after closing the preset time period of infusion Li door, obtain data from the pressure sensor collected, and adjust the alarm threshold value based on the data, wherein the pressure sensor to collect data on the hardness of the reaction of the infusion line.

[0063] 通常,输液管路的硬度越大,为确保报警的准确性,则需要将增大报警阈值。 [0063] Generally, the harder the infusion line, to ensure the accuracy of the alarm, it is necessary to increase the alarm threshold. 所以,本实施例中,通过报警阈值调整模块205,可以实现动态调整报警阈值的目的,不管是为了适应输液管路本身的硬度变化,还是为了适应不同的开放耗材,都能保证上阻塞报警的准确性,避免上阻塞报警的准确性因输液管路的硬度变化而降低。 Therefore, in this embodiment, the alarm threshold adjustment module 205, may be dynamically adjusted object alarm threshold, whether it is to accommodate the change in hardness infusion line itself, or to accommodate different open consumables, can guarantee occlusion alarm accuracy, the accuracy of avoiding the clogging alarm infusion line due to change in hardness decreases.

[0064] 请参考图5,本实施例中,上述步骤1.4具体包括: [0064] Referring to FIG 5, in this embodiment, the step 1.4 includes:

[0065] 步骤3.1:阻塞识别区判断模块202判断上压力传感器采集的数据是否进入阻塞识别区,如果否,则继续检测;如果是,则转到步骤3.2。 [0065] Step 3.1: blocking recognition section determines whether the data on the pressure sensor module 202 determines collected into the blocking identification area, if not, continues to detect; if yes, go to step 3.2. .

[0066] 步骤3.2:当阻塞识别区判断模块202检测到进入阻塞识别区时,处理模块203记录位于阻塞识别区起点的数据,作为初始数据。 [0066] Step 3.2: determining when the blocking zone identification module 202 detects the identification area enters the blocking, the processing module 203 in the data identification area recording starting point obstruction, as initial data.

[0067] 步骤3.3:当处于阻塞识别区期间,处理模块203实时获取上压力传感器采集的数据,计算该实时数据与初始数据的差值。 [0067] Step 3.3: when the recognition region is blocked during the processing module 203 acquires the real-time data collected by the pressure sensors, calculates the difference between the real-time data and the initial data.

[0068] 步骤3.4:处理模块203对该差值与第二累计值的和进行处理,得到处理后的比较值。 [0068] Step 3.4: the difference between the processing module 203 and the second integrated value, to give the comparison value after the treatment. 具体的,对该差值与第二累计值的和进行处理,可以是通过一具体的换算公式,将该差值与第二累计值的和换算成用于与报警阈值进行比较的比较值。 Specifically, the difference between the integrated value and the second processing may be by a particular conversion formula, in terms of the difference value and the second integrated value and a comparison value to be compared with the alarm threshold. 其中,第二累计值为当前阻塞识别区之前的各个阻塞识别区的终点与起点上压力传感器采集的数据的差值之和。 Wherein the second integrated value and the difference between end and start of the previous individual identification area obstruction blocking recognition of the currently acquired pressure sensor data. 当前阻塞识别区为第一阻塞识别区时,第二累计值为0。 When the current blocking first blocking region is identified identification area, the second accumulated value is 0.

[0069] 步骤3.5:处理模块203判断该比较值是否小于报警阈值,如果是,则转到步骤 [0069] Step 3.5: the processing module 203 determines whether the comparison value is less than the alarm threshold, if yes, go to step

3.6 ;如果否,则触发上阻塞报警。 3.6; if not, an alarm is triggered on the obstruction.

[0070] 步骤3.6:阻塞识别区判断模块202判断上压力传感器采集的数据是否离开当前阻塞识别区,如果是,则处理模块203记录此时上压力传感器采集的数据与该初始数据的差值,用于更新第二累计值;如果否,则转到步骤3.3。 [0070] Step 3.6: blocking recognition section determines whether data acquisition module 202 determines the pressure sensor away from the current blocking recognition region, if so, processing the difference data with the pressure sensor initial data acquisition module 203 records this time, for updating a second accumulated value; if no, go to step 3.3.

[0071] 步骤3.7:处理模块203将该差值与第二累计值相加,作为更新后的第二累计值,之后阻塞识别区判断模块202继续检测下一个阻塞识别区。 [0071] Step 3.7: The processing module 203 and the second difference cumulative value sum, as the second cumulative value updated, after blocking with continued identification area detection module 202 determines a blocking recognition area.

[0072] 需要说明的是,本实施例中,步骤1.3在报警阈值对比时,相当于在第二个阻塞识别区以后,都将当前阻塞识别区计算得到的差值与第一差值相加,对得到的和进行处理后,再与报警阈值进行对比,以判断是否需要触发上阻塞报警。 [0072] Incidentally, in this embodiment, step 1.3 when the alarm threshold value comparison, is equivalent to the blocking after the second recognition region, are calculated difference value with a current blocking region identifying adding the first difference , to give after treatment and then compared with the alarm threshold to determine whether the occlusion needs to trigger an alarm. 其原因在于: The reason is that:

[0073] 上阻塞报警阈值通常会根据统计的第一识别区终点与起点的数据所能得到的差值(即第一差值)的大小来设定,即报警阈值的设定会参考统计的第一差值,因此,在本实施例中,将第一差值进行保留,在第二个阻塞识别区以后,都将当前阻塞识别区计算得到的差值与第一差值相加,再与报警阈值进行对比,以判断是否需要触发上阻塞报警。 [0073] blocking the alarm threshold is usually set according to the size of the first end region and the identification data can be obtained starting from a statistical difference (i.e., first difference), i.e., alarm threshold settings will reference statistics first difference, therefore, in the present embodiment, the first difference value retained, blocked after the second identification area, are calculated and the difference between the current blocking region identifying adding the first difference, then compared with the alarm threshold to determine whether the occlusion needs to trigger an alarm.

[0074] 另外,本实施例中,步骤1.3在报警阈值对比时,相当于只采用了两个阻塞识别区(第一阻塞识别区与当前阻塞识别区)的数据差值之和与报警阈值进行对比,这是因为液体高流速在运行的过程中会产生波动数据,如果采用低流速的算法(步骤1.4),将多个阻塞识别区的数据差值进行累加,流体波动产生的应力会施加到上压力传感器上,长时间运行就会导致波动的干扰数据触发上阻塞压力报警,影响上阻塞报警的准确性。 [0074] In the present embodiment, at step 1.3 when the alarm threshold value comparison, is equivalent to using only two blocking recognition region (a first current blocking region and blocking identification region identification), and alarm threshold data for the difference in contrast, since the liquid will fluctuate high flow of data during operation, if a low flow rate using an algorithm (step 1.4), the difference data identifying a plurality of blocking regions accumulates, the fluid stress is applied to the fluctuations will a pressure sensor, the data long run will lead to interference fluctuations trigger the occlusion pressure alarm, the alarm on the impact of obstruction of accuracy.

[0075] 而通过研究,在高流速的情况下,达到报警阈值以触发上阻塞报警仅需要1〜2个阻塞识别区的数据差值之和即可,而不像低流速那样需要多个阻塞识别区的数据差值之和。 [0075] through research, in the case of high flow rate, reaches the alarm threshold to block and to trigger an alarm need only a difference of 1 to 2 more congestion data identification area, but not as low flow rates requiring multiple obstruction the difference between the data and the identified region. 因此在高流速算法设计的时候,为了避免产生误报,结合高流速的特点,针对高流速采用2个识别区的方法,在第二阻塞识别区以后,如果识别不出报警,即认为是干扰导致的,剔除该阻塞识别区的数据。 Thus, when high flow algorithm design, in order to avoid false alarms, the characteristics of high flow rates, the use of two methods for identifying regions of high flow rate, after the second blocking identification area, if not recognize the alarm, i.e. as interference result, the data area excluding the blocking recognition.

[0076] 低流速算法中,之所以不剔除累计数,直接累计多个阻塞识别区的数据,是基于两个方面的考虑:(1)低流速运行的过程中基本不存在波动数据的干扰;(2)达到报警阈值以触发上阻塞报警需要多个阻塞识别区的数据差值之和,如果采用高流速仅2个阻塞识别区的方法,那么无法达到设定的报警阈值,从而无法实现准确上阻塞报警。 [0076] The low-flow algorithm, the cumulative number of reason is not removed, the cumulative data directly identifying a plurality of blocking regions, is based on two considerations: the interference fluctuation data process (1) low flow running substantially absent; (2) reaches the alarm threshold to trigger the alarm blocking the required difference data recognition region and a plurality of obstruction, if the method is only two high flow obstruction identification region, then you can not reach the alarm threshold settings, which can not achieve accurate the blocking alarm.

[0077] 所以,本实施例中,将高速运行和低速运行模式分别对待,实现了上阻塞报警的宽流速检测范围。 [0077] Therefore, in the present embodiment, the high-speed operation and low speed operation mode is treated separately to achieve a blocking alarm on a wide range of flow rate detection. 并进一步针对高速运行和低速运行的特点,设计相应的高流速算法和低流速算法,使得算法能够更好地适用高流速和低流速运行情况,使得报警更加准确。 And further for high-speed operation and low speed operation characteristics, design appropriate high flow rate and low flow rate algorithms algorithm, such algorithm can be better suited for high flow rate and low flow operation, so that more accurate alarm.

[0078] 当然,本实施例中,步骤1.3和步骤1.4只是优选的一种方式,在其他实施例中,也可以采用其他实现方式,或者在本实施例的基础上进行适当变换。 [0078] Of course, in this embodiment, step 1.3 step 1.4 is just one preferred embodiment, in other embodiments, other implementations may be employed, or the appropriate conversion based on the embodiment of the present embodiment.

[0079] 例如,在另一实施例中,步骤1.3在报警阈值对比时,将当前阻塞识别区计算得到的差值与第一差值、第二差值相加,将得到的和进行处理后,再与报警阈值进行对比,以判断是否需要触发上阻塞报警。 After [0079] For example, in another embodiment, step 1.3 when the alarm threshold value comparison, the current blocking recognition region and the first difference calculating a difference obtained by adding the second difference, and the resultant treated , then compared with the alarm threshold to determine whether the occlusion needs to trigger an alarm. 其中,第二差值指第二阻塞识别区终点与起点的数据的差值。 Wherein the second difference means the difference data of the second end and start blocking the identification area.

[0080] 同样,在另一实施例中,步骤1.4也可以采用类似本实施例步骤1.3中的高流速算法,为了尽量减小上述缺陷对报警准确性的影响,可以在报警阈值对比时,累计预设个数(例如4个)的阻塞识别区的数据与报警阈值进行对比,以判断是否需要触发上阻塞报警。 [0080] Similarly, in another embodiment, step 1.4 may be used similarly to the present embodiment a high flow rate algorithm in the embodiment in step 1.3, in order to minimize the influence of the accuracy of the aforementioned drawbacks of the alarm, the alarm can be contrast threshold, the accumulated data and alarm threshold preset number (e.g., four) blocking the recognition region are compared to determine whether the occlusion needs to trigger an alarm.

[0081] 优选的,上阻塞报警方法还包括步骤:在安装好输液管路,关闭输液栗门的预设时间段后,报警阈值调整模块205获取上压力传感器采集的数据,并根据该数据调整报警阈值,其中,上压力传感器采集的该数据反应了输液管路的软硬程度。 [0081] Preferably, the method further comprising the step of blocking the alarm: After installing the infusion line, infusion Li preset period of time off the door, the alarm threshold adjustment module 205 acquires data from the pressure sensor collected, and adjusted according to the data alarm threshold, wherein the pressure sensor to collect data on the hardness of the reaction of the infusion line.

[0082] 在安装管路的时候,关上输液栗门的过程中,上压力传感器受力而产生数据变化。 [0082] In the installation of the pipeline, generating off data changes during the infusion Li of the door, the force on the pressure sensor. 本实施例中,通过在管路安装时刻,对上压力传感器反馈出的压力值进行判断,从而判断当前输液管路的软硬程度。 In this embodiment, the determination by the line installation time, on the pressure sensor feedback pressure value, to determine the hardness of the current infusion line. 具体的,在安装好输液管路后,合上输液栗门后,门在位开关会检测到门已经正常合上,此时会进行计时,预设时间段后读出此时上压力传感器的数值。 At this time, read the pressure sensor after Specifically, after the infusion line installed, close the infusion Li door, the door switch detects that the bit has a normal door closing, will be clocked at this time, the predetermined time period value. 本实施例中,读出上压力传感器的数值后,采用查表的方式来判断当前输液管路的软硬程度,从而动态调整报警阈值。 After the value of the pressure sensor of the present embodiment, the readout, the use of table lookup to determine the hardness of the infusion line current to dynamically adjust the alarm threshold.

[0083] 优选的,上述预设时间段可以设置为4_6s,具体的,可以设置为5s,通过统计分析,在合上输液栗门5s后上压力传感器的受力最真实,用于分析输液管路的软硬程度最为准确。 [0083] Preferably, the above predetermined time period may be set to 4_6s, specifically, can be set to 5s, through statistical analysis, Li door 5s after infusion truest force on the pressure sensor in the engagement, the infusion tube for analysis the hardness of the most accurate way. 另外,采用查表的方式判断当前输液管路的软硬程度时,表中的数据可以通过大量不同输液管路的测试数据得到。 Further, when using the table lookup determines the hardness of the current infusion line, the data table can be obtained by a large number of test data for different infusion line.

[0084] 具体的,表内可以记录上压力传感器的数值与报警阈值的对应关系,当获取到上压力传感器的数值时,查询得到对应的报警阈值。 [0084] Specifically, the correspondence relationship may be recorded on the alarm threshold value and a pressure sensor in the table, when the acquired value of the pressure sensor, the query to obtain the corresponding alarm thresholds. 表内也可以记录上压力传感器的数值、输液管路硬度、报警阈值三者的对应关系,当获取到上压力传感器的数值时,先查询得到对应的输液管路的硬度,再根据输液管路的硬度调节对应的报警阈值。 May be recorded in the table on the value of the pressure sensor, the hardness of the infusion line, the correspondence relationship of the three alarm thresholds, when the acquired value of the pressure sensor, corresponding to the first query to obtain a hardness of the infusion line, and then the infusion line according to adjusting the hardness of a corresponding alarm thresholds.
