[0025] 本发明针对呼吸设备堵塞位置检测问题,提出ー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, monitoring method and apparatus ー species clogging breathing apparatus described specific embodiments of the method and apparatus for monitoring the clogging of the breathing apparatus control:

[0026] 图1是根据本发明实施例所述ー种呼吸设备堵塞的监测方法的主要流程图;參见图1所示,ー种呼吸设备堵塞的监测方法,包括: [0026] FIG. 1 is an embodiment of the present invention is a main flowchart kinds of respiratory monitoring method of plugging the apparatus ー;, ー kinds respiratory monitoring method plugging apparatus Referring to Figure 1, comprising:

[0027] a:检测所述呼吸设备的吸气端和呼气端的压カ和流量;以及 [0027] a: ka pressure and the flow rate detecting end inspiratory and expiratory respiratory terminal device;

[0028] b:根据所述压カ和流量进行计算,井根据计算结果确认所述呼吸设备的堵塞位置。 [0028] b: pressure is calculated based on the grades and the flow blocking position of the wells to confirm 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ロ205上安装吸气压カ传感器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的另外ー侧,在所述呼吸设备的呼气端ロ217的排气端219上设置呼气压カ传感器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 for monitoring the respiratory device shown in Figure 2, the display monitor 203 disposed on the breathing apparatus hosts 201, 205 ro mounted on the intake end of the intake of the breathing apparatus ka pressure 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; ー in further side of the respiratory device host 201, the end expiratory breathing apparatus ro ka expiratory pressure sensor 223 is provided and the expiratory flow sensor 221 on the end 219 of the exhaust gas 217, the gas flow direction through the exhalation conduit 225 Y-fitting 213, the UE enters an analog airway UE 215.

[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,所述吸气压カ传感器207、吸气流量传感器209以及呼气压カ传感器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 ka, inspiratory flow and expiratory pressure sensor 209 and the sensor 223 ka expiratory flow measured by sensor 221 data 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)采集到压カ和流量数据。 The breathing apparatus must be able to breathe when the real time user (<= IOms) acquired pressure and flow data ka. 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I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I分钟的通气量。 The minute ventilation is calculated as the last eight breaths, or breaths I minute take a small value of the inspiratory tidal volume is converted to the accumulated value I 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、排气端ロ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: plugging the respiratory tract, and blockage of the exhaust end of the ro 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カ就会有差异,而堵塞管道两端的压カ可以分别用吸气压カ传感器207和呼气压カ传感器223測量出来,这时用两个压カ传感器的压カ差值进行比较,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, the ends of the pipe clogged during normal breathing pressure difference will ka, ka pressed ends of the pipe may be clogged, respectively, and the intake pressure sensor 207 ka ka expiratory pressure sensor 223 measured, when compared with the pressure difference between two pressure ka ka sensors continuously for more than a period of time can be considered to occur a certain amount of clogging of the pipeline.

[0033] 当所述排气端ロ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,呼气压カ需要下降到设定PEEP值,这时如果排气端堵塞,则呼气压カ不能下降,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 end ro clogging, because the inspiratory phase exhalation valve is closed, it is determined whether or not clogging, and in expiratory phase, expiratory need exhaust end, ka need expiratory pressure PEEP value drops to the set, then if the exhaust end blocked, ka expiratory pressure not fall, because the user is not discharged gas, expiratory tidal volume is also smaller than the intake air amount, so when the call PEEP gas amount exceeds the 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吋,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 inch airway blockage, if capacity control mode, the inspiratory tidal volume will be less than the value for the voltage control 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,如果压カ差超过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 grades that can plug the pipeline. 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. 在毎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。 Performed at every start determination inhale, a breath time does not exceed determined 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是实现上述ー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,ー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カ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カ和流量;以及计算模块305,用于根据所述压カ和流量进行计算,井根据计算结果确认所述呼吸设备的堵塞位置。 [0036] FIG. 3 is a schematic view of the device structure to achieve the above-described method of monitoring ー kinds of clogging of the breathing apparatus, the breathing apparatus clogging monitoring apparatus shown in Figure 3, the clogging of the breathing apparatus ー species monitoring apparatus comprising: a verifying module 301 detection module 303, the suction side pressure and flow ka and for detecting the end expiratory breathing apparatus;; and calculating means for venting before normal parity errors within a predetermined range of said pressure and flow rate ka 305, for performing calculation according to the pressure and flow rate ka, confirming that the well 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ロ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カ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 respiratory breathing apparatus duct congestion information; acquiring traffic information of the exhaust end of the breathing apparatus and ro external device; and obtaining the user's end of the breathing apparatus airway congestion information; and a determining module 3052 for determining the suction side and end expiratory pressure within the breathing apparatus ka difference value exceeds a predetermined time range; determining whether the expiratory breathing apparatus whether PEEP pressure exceeds a preset value; and the breathing apparatus expiratory tidal volume and inspiratory tidal volume is beyond a predetermined range within a predetermined time value; and determining the amount of respiratory minute ventilation equipment 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.
