[0025] 本发明针对呼吸设备堵塞位置检测问题,提出一种呼吸设备堵塞的监测方法及装置,具体介绍控所述呼吸设备堵塞的监测方法及装置的实施例: [0025] The present invention is directed to apparatus closing position detecting respiratory problems, a method and apparatus to monitor a clogging of respiratory apparatus, in particular embodiments described monitoring method and apparatus for controlling the clogging of the breathing apparatus:

[0026] 图1是根据本发明实施例所述一种呼吸设备堵塞的监测方法的主要流程图;参见图1所示,一种呼吸设备堵塞的监测方法,包括: [0026] FIG. 1 is a main flowchart of a method of monitoring the clogging of the breathing apparatus embodiment of the present invention embodiment; clogging the apparatus A respiratory monitoring method shown in Figure 1, comprising:

[0027] a :检测所述呼吸设备的吸气端和呼气端的压力和流量;以及 [0027] a: detecting the pressure and flow and the suction side end expiratory breathing device;

[0028] b :根据所述压力和流量进行计算,并根据计算结果确认所述呼吸设备的堵塞位置。 [0028] b: calculated according to the pressure and flow rate, and confirms the blocking position breathing apparatus according to the results.

[0029] 将上述呼吸设备堵塞的监测方法具体应用到呼吸设备上,如图2所示,在呼吸设备主机201上设置监控显示器203,在所述呼吸设备的吸气端口205上安装吸气压力传感器207和吸气流量传感器209,气流方向沿吸气管道211经用户端气道213的Y型三通进入模拟用户端215 ;在所述呼吸设备主机201的另外一侧,在所述呼吸设备的呼气端口217的排气端219上设置呼气压力传感器223和呼气流量传感器221,所述气流方向沿呼气管道225 经用户端气道213的Y型三通进入模拟用户端215。 [0029] The clogging the respiratory apparatus to the particular application method of monitoring the breathing apparatus, as shown in FIG 2 is provided on display 203 to monitor the breathing apparatus body 201, mounted on the suction port of the suction pressure of the breathing apparatus 205 sensor 207 and intake air flow rate sensor 209, the intake pipe 211 along the air flow direction through the Y-fitting 213, the UE enters an analog airway UE 215; on the other side of the respiratory device host 201, in the breathing apparatus exhalation pressure sensor 223 is provided and the expiratory flow sensor 219 on the end of exhalation exhaust port 217 of 221, the direction of the gas flow through the exhalation conduit 225 Y-fitting 213, the UE enters the airway of the user terminal 215 analog.

[0030] 在正常通气前要通过校验保证在同样的压力和流速条件下,所述吸气压力传感器207、吸气流量传感器209以及呼气压力传感器223和呼气流量传感器221测得的数据都在误差精度范围内。 [0030] Before the normal ventilation by checking to ensure that under the same pressure and flow conditions, the intake pressure sensor 207, sensor 209 and intake air flow rate sensor 223 and the exhalation pressure sensor 221 measured expiratory flow data We are within the range of error accuracy. 所述呼吸设备必须在用户呼吸时都能够实时(<=IOms)采集到压力和流量数据。 The breathing apparatus must be able to breathe when the real time user (<= IOms) acquired pressure and flow data. 通过对两套传感器的采集数据进行计算分析,即可对呼吸设备的堵塞进行监测。 Two sets of data collected by the sensor is calculated analysis, clogging of the breathing apparatus to be monitored. 通过对上述传感器的数据计算能得到用户的吸气潮气量和呼气潮气量以及分钟通气量,其中,所述吸气潮气量的计算为吸气阶段吸气流量传感器209与所述呼气流量传感器221测得流量的差值。 The data of the sensor is used to obtain the user's inspiratory tidal volume and expiratory tidal volume and minute ventilation, wherein the inspiratory tidal volume is calculated inspiratory flow during the inspiratory phase and the expiratory flow sensor 209 sensor 221 measured by the flow rate difference. 所述呼气潮气量的计算为呼气阶段所述呼气流量传感器221与所述吸气流量传感器209测得流量的差值。 Calculating the tidal volume to expiratory expiratory phase difference 221 and the expiratory flow sensor 209 to the intake air flow rate measured by flow sensor. 所述分钟通气量的计算为过去8次呼吸或1分钟的呼吸次数取小值的所述吸气潮气量的累加值换算到1分钟的通气量。 The minute ventilation is calculated as the last eight breaths, or breaths a minute take a small value of the inspiratory tidal volume is converted to the accumulated value of one minute ventilation.

[0031] 通过上述传感器所采集的数据进行的计算,本技术方案可以监测三个方面的堵塞,包括:呼吸管道的堵塞、排气端口及其外接器件的堵塞、用户端气道的堵塞。 [0031] The calculation performed by the data collected by the sensor, the present technology may monitor clogging three areas, comprising: a breathing pipe clogging and blockage of the exhaust port of the external device, the UE airway plugging.

[0032] 当所述呼吸管道发生堵塞时,在正常呼吸时堵塞管道两端的压力就会有差异,而堵塞管道两端的压力可以分别用吸气压力传感器207和呼气压力传感器223测量出来,这时用两个压力传感器的压力差值进行比较,在一段时间内连续超过一定量即可认为出现管道堵塞。 [0032] When clogging of the respiratory tract occurs, during normal breathing will clog pressure difference across the pipeline, clogging of the ends of the pipe 207 and the exhalation pressure may be measured by a pressure sensor 223, respectively, intake pressure sensor, which when compared with the pressure difference between two pressure sensors, a period of time that can be continuously exceeds the amount of pipe blockage occurs.

[0033] 当所述排气端口及其外接器件发生堵塞时,在吸气阶段因为呼气阀是关闭时,所以不能判断是否发生堵塞,而在呼气阶段,呼气端需要排气,呼气压力需要下降到设定PEEP 值,这时如果排气端堵塞,则呼气压力不能下降,而由于用户气体没有排出,则呼气潮气量也会小于吸入的气量,所以当呼气末正压超过设定值一定量,并且呼气潮气量小于吸气潮气量一定值时即可认为出现排气端及其外接器件堵塞。 [0033] When the external device and the exhaust port clogging, because the inspiratory phase exhalation valve is closed, it is determined whether or not clogging occurs, and the expiratory phase, expiratory need exhaust end, call air pressure drop required to set PEEP value, then if the exhaust end blockage, the exhalation pressure can not be decreased, while since the user is not discharged gas, expiratory tidal volume is also smaller than the intake air amount, so when a positive end-expiratory a certain amount of pressure exceeds a set value, and expiratory tidal volume is less than the discharge end can be considered to occur and an external device clogging inspiratory tidal volume constant.

[0034] 当用户端气道发生堵塞时,如果是容控模式,则吸气潮气量会小于设定值,对于压控模式,则吸气潮气量会比较小,所以可以通过潮气量低这个特征进行用户端气道堵塞判断。 [0034] When the UE airway blockage occurs, if the control mode is volume, inspiratory tidal volume will be less than the set value for the voltage controlled mode, the inspiratory tidal volume will be relatively small, it is possible by the low tidal volume wherein a user terminal is determined airway obstruction. 用户的屏气、吸气对抗、咳嗽等行为也会导致单次吸气潮气量出现上述现象,为了防止出现误报警,需要用多次呼吸的潮气量进行判断,即当多次呼吸潮气量低于一定值时,认为用户端气道发生堵塞,实际使用分钟通气量进行判断。 Breath, inhale confrontation, coughing and other behavior can lead to a single user's inspiratory tidal volume above phenomenon, in order to prevent false alarms, the need for judgment tidal volume breathing many times, that is when breathing many times lower than the tidal volume constant value, the UE that the airway blockage occurs, the actual amount is determined using minute ventilation.

[0035] 优选地,在判断吸气管道和呼气管道堵塞时,如果压力差超过5cmH20即可认为管道堵塞。 [0035] Preferably, when determining the suction duct and exhalation pipe plug, if the pressure difference exceeds 5cmH20 pipe blockage can be considered. 从堵塞到判断出堵塞的时间不超过200ms ;在判断排气端堵塞时,当实际呼气末正压比用户设定呼气末正压高IOcmH2O,且呼气潮气量小于吸气潮气量的50%时认为是排气端堵塞。 From clogging judged to clogging no more than 200ms; at the discharge end blockage determination, when the actual end-expiratory pressure PEEP is set higher than the user IOcmH2O, expiratory tidal volume and inspiratory tidal volume is less than 50% think that the discharge end is blocked. 在每次吸气开始时进行判断,判断时间不超过一次呼吸时间;在判断用户端气道堵塞时,当连续三次呼吸的吸气潮气量(不能是呼气,因为呼气低可能是因为泄漏导致的)低于设定潮气量的80%,认为用户端气道堵塞。 In each inspiration start determination, it is determined breath time does not exceed one time; when determining the UE airway obstruction when the inspiratory tidal volume three consecutive breaths (no exhalation, exhalation low as possible because the leak result) less than 80% of the set tidal volume, airway obstruction that the UE. 判断时间为三次呼吸的时间。 Judgment time for the third time to breathe. 用连续三次的原因在于防止用户吸气对抗或其它原因引起误报警。 The reason is that with three consecutive prevent users from inhalation or against other causes of false alarms. [0036] 图3是实现上述一种呼吸设备堵塞的监测方法的装置结构示意图,所述呼吸设备堵塞的监测装置,如图3所示,一种呼吸设备堵塞的监测装置包括:校验模块301,用于在正常通气前校验所述压力和流量的误差在预设范围内;检测模块303,用于检测所述呼吸设备的吸气端和呼气端的压力和流量;以及计算模块305,用于根据所述压力和流量进行计算,并根据计算结果确认所述呼吸设备的堵塞位置。 [0036] FIG. 3 is a structural diagram of an apparatus to realize a method of monitoring the clogging of a respiratory apparatus, the respiratory monitoring device clogging means, shown in Figure 3, the plugging apparatus A respiratory monitoring apparatus comprising: a verifying module 301 for an error check before normal venting of the pressure and flow rate within a preset range; detection module 303, a device for detecting the respiratory pressure and flow inspiratory and expiratory terminal end; and a calculation module 305, for performing calculation according to the pressure and flow rate, and confirms the blocking position breathing apparatus according to the results. 所述计算模块305包括:获取模块3051,用于获取所述呼吸设备的呼吸管道堵塞信息;获取所述呼吸设备的排气端口以及外接器件的堵塞信息;以及获取所述呼吸设备的用户端气道的堵塞信息;以及判断模块3052,用于判断所述呼吸设备在定值时间内的吸气端和呼气端的压力差值是否超出预设范围;判断所述呼吸设备的呼气未正压PEEP是否超过预设值;以及所述呼吸设备的呼气潮气量和吸气潮气量是否在定值时间内超出预设范围;以及判断所述呼吸设备的分钟通气量是否低于预设值。 The calculation module 305 comprises: an obtaining module 3051, configured to obtain the breathing apparatus respiratory tract congestion information; acquiring congestion information and the exhaust port of the breathing apparatus external device; and the UE obtaining the air breathing apparatus Road traffic information; and a determining module 3052, configured to determine the pressure difference between the end inspiratory and expiratory breathing device end value within a predetermined time exceeds a predetermined range; Analyzing the expiratory positive pressure breathing apparatus not whether PEEP exceeds a preset value; and expiratory tidal volume and the inspiratory tidal volume breathing apparatus exceeds a predetermined value within a predetermined time range; and determining that the minute ventilation of the breathing apparatus is lower than a preset value. 所述判断模块3052包括:确认模块(图中未示),用于确认所述呼吸设备的堵塞位置。 The determining module 3052 comprises: an acknowledgment (not shown) means for plugging said position confirmation breathing apparatus.
