本发明涉及医疗设备控制技术领域，具体地，涉及一种提高无创通气时氧气利用率的控制方法及其装置。The invention relates to the technical field of medical equipment control, in particular to a control method and device for improving oxygen utilization rate during non-invasive ventilation.
背景技术Background technique
在现代临床医学中，呼吸机作为一种能代替、控制或改变人的正常生理呼吸，增加肺通气量，改善呼吸功能，减轻呼吸功消耗，节约心脏储备能力的装置，能够起到预防和治疗呼吸衰竭，减少并发症，挽救及延长病人生命的作用，被普遍应用于各种原因所致的呼吸衰竭、呼吸支持治疗和急救复苏中，在现代医学领域内占有十分重要的位置。现有呼吸机的工作原理一般都是通过利用气体的压力差来实现向患者气道输送或排除气体：当患者吸气时，呼吸机使气体压力增高，通过管道与患者呼吸道插管连接，气体经气道、支气管，直接流向肺泡；而患者呼气时呼吸机管道与则大气相通，患者肺泡内的压力大于大气压力，肺泡内气体即自行排除，直至与大气压相等。In modern clinical medicine, as a device that can replace, control or change people's normal physiological breathing, increase pulmonary ventilation, improve respiratory function, reduce breathing work consumption, and save heart reserve capacity, it can prevent and treat Respiratory failure, reducing complications, saving and prolonging the life of patients, is widely used in respiratory failure caused by various reasons, respiratory support treatment and emergency resuscitation, and occupies a very important position in the field of modern medicine. The working principle of the existing ventilator is generally to use the pressure difference of the gas to realize the delivery or removal of gas to the patient's airway: when the patient inhales, the ventilator increases the gas pressure, and is connected to the patient's respiratory tract through a pipeline, and the gas Through the airway and bronchus, it flows directly to the alveoli; when the patient exhales, the ventilator tube is connected to the atmosphere, and the pressure in the patient's alveoli is greater than the atmospheric pressure, and the gas in the alveoli is automatically eliminated until it is equal to the atmospheric pressure.
由于现有的呼吸机本身并不能产生氧气，若患者对吸入的氧气浓度也有一定要求的话，则只能另外配置一台制氧机来获得高浓度的氧气。目前市场上通用的呼吸机以及制氧机其功能及特点相对固定，其中，呼吸机可以保持患者呼吸道畅通，但其本身不能制造氧气；而制氧机可以产生氧气从而提高患者吸入气体的氧浓度，但却不能保持患者呼吸道通畅，无法辅助呼吸。但是，这两种仪器无法相互配合使用，以家用无创正压通气式呼吸机以及便携式制氧机为例，当患者同时使用上述两个机器时，无创正压通气式呼吸机会对便携式制氧机的触发造成干扰，从而导致便携式制氧机无法正常运行。另一方面，现有的便携式无创呼吸机或者制氧机只能分别通过自带电池或车载电源等方式进行供电，以满足患者在外出、旅行甚至飞机上接受无创通气治疗或者氧疗的需求，当患者只需使用呼吸机或者制氧机之一进行相应治疗时，商场上现有的产品已经可以很好地满足患者需求；但当患者需要同时使用这两种机器，即在通过呼吸机保持呼吸道通畅的同时获取制氧机提供的高浓度氧气时，现有的产品明显无法有效满足患者需求，患者只能同时携带并且交替地使用呼吸机以及制氧机，以获得两者提供的不同服务。Since the existing ventilator itself cannot produce oxygen, if the patient also has certain requirements for the inhaled oxygen concentration, an additional oxygen concentrator can only be configured to obtain high-concentration oxygen. At present, the functions and characteristics of ventilators and oxygen concentrators commonly used in the market are relatively fixed. Among them, the ventilator can keep the patient's airway unobstructed, but it cannot produce oxygen itself; the oxygen concentrator can generate oxygen to increase the oxygen concentration of the patient's inhaled gas , but it cannot keep the patient's airway open and cannot assist breathing. However, these two instruments cannot be used in conjunction with each other. Taking a household non-invasive positive pressure ventilation machine and a portable oxygen concentrator as an example, when a patient uses the above two machines at the same time, the non-invasive positive pressure ventilation machine will have a negative effect on the portable oxygen concentrator. The triggering of the device causes interference, which prevents the portable oxygen concentrator from functioning properly. On the other hand, the existing portable non-invasive ventilators or oxygen concentrators can only be powered by their own batteries or vehicle-mounted power supplies to meet the needs of patients receiving non-invasive ventilation therapy or oxygen therapy when going out, traveling or even on the plane. When the patient only needs to use one of the ventilator or oxygen concentrator for corresponding treatment, the existing products on the market can already meet the needs of the patient; When the airway is unobstructed and the high-concentration oxygen provided by the oxygen concentrator is obtained, the existing products obviously cannot effectively meet the needs of patients. Patients can only carry the ventilator and the oxygen concentrator at the same time and use them alternately to obtain different services provided by the two. .
现有的用户对于仪器使用上的便利性要求是很高的，尤其在用户体验上。用户体验的微小差异往往决定了一款产品的被接受程度，这对存在着充分竞争的医疗设备市场构成了强大的竞争差别。以上述情况为例，在很多时候，患者需要一种能够在向患者输送氧气的同时保持患者呼吸道畅通的仪器，例如，通过呼吸机控制制氧机的运作，当呼吸机检测到患者吸气时控制制氧机制造氧气，通过利用呼吸机控制制氧机脉冲氧气容量的发放来合理规划制氧机制氧及输氧时机，从而提高无创通气时的氧气利用率。Existing users have high requirements for the convenience of instrument use, especially in terms of user experience. Small differences in user experience often determine the degree of acceptance of a product, which constitutes a strong competitive differentiation in the fully competitive medical device market. Taking the above situation as an example, in many cases, patients need an instrument that can keep the patient's airway open while delivering oxygen to the patient. For example, the operation of the oxygen generator is controlled by the ventilator. When the ventilator detects that the patient is inhaling Control the production of oxygen by the oxygen generator, and use the ventilator to control the release of the pulse oxygen capacity of the oxygen generator to reasonably plan the oxygen generator and the timing of oxygen delivery, so as to improve the oxygen utilization rate during non-invasive ventilation.
在现阶段，没有一个非常好的方法能够解决上述提到的问题。大多数情况下，患者都只能选择使用呼吸机或者制氧机之一以保持患者呼吸道通畅或者获得具有高浓度氧气的气体，没有提供一种有效的控制方法，使得呼吸机以及制氧机能够有效配合使用、协同工作应用于既需要无创正压通气治疗又需要氧疗的患者。At this stage, there is no very good way to solve the above-mentioned problems. In most cases, patients can only choose to use one of a ventilator or an oxygen generator to keep the patient's airway unobstructed or to obtain a gas with a high concentration of oxygen. An effective control method is not provided so that the ventilator and the oxygen generator can Effectively used in conjunction and working together, it is applied to patients who need both non-invasive positive pressure ventilation therapy and oxygen therapy.

本领域技术人员理解，在本发明的实施方式中，所述控制方法可以被储存于存储器中并通过相应的指令执行系统执行的软件或固件实现，例如通过对相关步骤设置程序来指令相关硬件完成，所述程序可以存储于一种计算机可读存储介质中。进一步地，可以通过相应的处理模块集成本发明提供的相关功能单元，这都不影响本发明的实质内容，在此不予赘述。Those skilled in the art understand that, in the embodiments of the present invention, the control method can be stored in the memory and implemented by software or firmware executed by the corresponding instruction execution system, for example, by setting a program for the relevant steps to instruct the relevant hardware to complete , the program can be stored in a computer-readable storage medium. Furthermore, related functional units provided by the present invention may be integrated through corresponding processing modules, which do not affect the essence of the present invention, and will not be described in detail here.
根据本发明提供的控制方法，配合使用所述无创呼吸机和便携式制氧机同时进行无创正压通气治疗和氧疗时，所述无创呼吸机通过数据线与所述制氧机连接，所述数据线用于传输无创呼吸机对制氧机的控制信号以及制氧机向无创呼吸机发送的反馈信号，所述无创呼吸机和制氧机分别通过导气管与人体相连，制氧机通过导气管向用户传输氧气，无创呼吸机通过导气管帮助用户进行呼吸。According to the control method provided by the present invention, when the non-invasive ventilator and the portable oxygen generator are used together to perform non-invasive positive pressure ventilation therapy and oxygen therapy at the same time, the non-invasive ventilator is connected to the oxygen generator through a data line, and the The data line is used to transmit the control signal from the non-invasive ventilator to the oxygen generator and the feedback signal sent from the oxygen generator to the non-invasive ventilator. The trachea delivers oxygen to the user, and the non-invasive ventilator helps the user breathe through the airway.
图1示出根据本发明的第一实施例的，一种提高无创通气时氧气有效利用率的控制方法的流程图，具体地，首先执行步骤S101，获取用户呼吸时产生的压力流量数据，本领域技术人员理解，所述获取用户呼吸时产生的压力流量数据过程是一个实时监控的动态过程，用户在使用呼吸机时，所述呼吸机内设置的数据获取模块通过检测用户的呼吸状态获得对应的状态信息，并将状态信号转化为数据信号从而获得所述用户当前呼吸时产生的压力流量数据。更为具体地，所述数据获取模块包括压力传感模块以及流量传感模块，其分别用于检测所述导气管内的气体压力或者气体流量变化。更进一步地，所述压力流量数据包括用户呼吸时气体流量的方向以及其他参数。优选地，所述呼吸机通过“正方向”以及“负方向”来标识所述数据获取模块检测到的当前用户呼吸时产生的压力流量数据方向。Fig. 1 shows a flow chart of a control method for improving the effective utilization rate of oxygen during non-invasive ventilation according to the first embodiment of the present invention. Specifically, step S101 is first performed to obtain the pressure and flow data generated when the user breathes. Those skilled in the art understand that the process of acquiring the pressure and flow data generated when the user breathes is a dynamic process of real-time monitoring. When the user uses the ventilator, the data acquisition module installed in the ventilator obtains the corresponding state information, and convert the state signal into a data signal to obtain the pressure flow data generated when the user breathes currently. More specifically, the data acquisition module includes a pressure sensing module and a flow sensing module, which are respectively used to detect changes in gas pressure or gas flow in the airway tube. Furthermore, the pressure flow data include the direction of gas flow and other parameters when the user breathes. Preferably, the ventilator uses "positive direction" and "negative direction" to identify the direction of the current pressure and flow data generated when the user breathes detected by the data acquisition module.
接下来执行步骤S102，基于所述压力流量数据判断用户是否在进行吸气动作。具体地，所述数据获取模块能将对应的压力流量数据信息传输给呼吸机，使得所述呼吸机接收来自数据获取模块的数据信息并进行分析，从而判断出用户在该特定时刻是否处于吸气状态。本领域技术人员理解，所述数据获取模块设置在所述导气管内，包括压力传感模块以及流量传感模块，其用于对用户的呼吸状态进行感应。优选地，所述数据获取模块预先将用户吸气时产生的气体流量方向设定为正方向，即从呼吸机通过导气管经所述流量传感模块传输到用户肺部的气体流量方向为正，相应地，用户呼气时肺部产生的气体流量方向为负方向，即用户通过导气管释放气体经过所述流量传感模块传输到外界大气的气体流量方向为负。在一个优选例中，所述呼吸机基于所述流量传感模块对流经导气管的气体流量方向的判断结果确定用户在该特定时刻是否处于吸气状态，若用户当前正在进行吸气动作，则所述步骤S102的判断结果是肯定的；否则，则所述步骤S102的判断结果是否定的。进一步地，若所述步骤S102的判断结果是肯定的，则接下来进入步骤S103执行；若所述步骤S102的判断结果是否定的，即用户当前并未进行吸气动作，则接下来重新进入步骤S101执行。进一步地，所述数据获取模块还能感应用户呼吸过程中的呼吸频率、深度等其他参数，在此不予赘述。Next, step S102 is executed to determine whether the user is inhaling based on the pressure and flow data. Specifically, the data acquisition module can transmit the corresponding pressure and flow data information to the ventilator, so that the ventilator receives and analyzes the data information from the data acquisition module, so as to determine whether the user is inhaling at this specific moment. state. Those skilled in the art understand that the data acquisition module is arranged in the airway, and includes a pressure sensing module and a flow sensing module, which are used to sense the breathing state of the user. Preferably, the data acquisition module pre-sets the gas flow direction generated when the user inhales as a positive direction, that is, the gas flow direction transmitted from the ventilator to the user's lungs through the airway tube through the flow sensing module is positive. , correspondingly, when the user exhales, the gas flow direction generated by the lungs is negative, that is, the gas flow direction of the gas released by the user through the airway tube and transmitted to the external atmosphere through the flow sensing module is negative. In a preferred example, the ventilator determines whether the user is in an inhalation state at the specific moment based on the judgment result of the flow sensing module on the flow direction of the gas flowing through the airway. If the user is currently inhaling, then The judgment result of the step S102 is positive; otherwise, the judgment result of the step S102 is negative. Further, if the judgment result of step S102 is affirmative, proceed to step S103 for execution; if the judgment result of step S102 is negative, that is, the user is not currently performing an inhalation action, then proceed to re-enter Step S101 is executed. Further, the data acquisition module can also sense other parameters such as the user's breathing frequency and depth during the breathing process, which will not be described in detail here.
优选地，在所述步骤S103中，向所述制氧机发送制氧和/或输氧的控制指令。具体地，所述控制指令由呼吸机通过数据线发送给制氧机，所述控制指令包括制氧、输氧两项内容，本领域技术人员理解，呼吸机通过分析确定用户处于吸气状态后，通过配合获取的诸如呼吸频率以及呼吸深度等其他参数和制氧机本身的功能参数，可以在该特定时刻向制氧机只发出制氧或输氧指令中的一项指令，也可以在发出制氧指令的同时发出输氧指令，进一步地，所述控制指令还可以设定参数调控制氧和输氧的氧气量大小。在一个优选例中，所述制氧机默认处于待命状态，所述呼吸机确定用户当前正进行吸气动作后同时向所述制氧机发送制氧以及输氧的控制指令，使得所述制氧机能够基于所述控制指令制氧后将氧气经由导气管输送到用户面罩的混氧口，实现在用户吸气阶段向用户送氧的技术目的。Preferably, in the step S103, a control instruction of oxygen generation and/or oxygen delivery is sent to the oxygen generator. Specifically, the control command is sent by the ventilator to the oxygen generator through the data line, and the control command includes two contents of oxygen production and oxygen delivery. Those skilled in the art understand that after the ventilator determines that the user is in the inhalation state through analysis, By cooperating with other parameters obtained such as respiratory rate and breathing depth and the functional parameters of the oxygen generator itself, only one of the oxygen generation or oxygen delivery instructions can be issued to the oxygen generator at this specific moment, or the oxygen generator can be sent An oxygen infusion instruction is issued at the same time as the instruction, and further, the control instruction can also set parameters to adjust the amount of oxygen for oxygen control and oxygen infusion. In a preferred example, the oxygen generator is in the standby state by default, and the ventilator sends control instructions for oxygen generation and delivery to the oxygen generator after determining that the user is currently inhaling, so that the oxygen generator The machine can produce oxygen based on the control command and deliver the oxygen to the oxygen mixing port of the user's mask through the airway tube, so as to realize the technical purpose of sending oxygen to the user during the user's inhalation stage.
优选地，若所述步骤S102的判断结果是用户此时未进行吸气动作，则返回所述步骤S101执行，所述制氧机处于待命状态，直至所述数据获取模块采集到的用户呼吸产生的压力流量数据经所述步骤S102的判断符合吸气动作标准，才进入所述步骤S103执行。Preferably, if the judgment result of the step S102 is that the user has not performed an inhalation action at this time, then return to the step S101 for execution, and the oxygen generator is in a standby state until the user's breath collected by the data acquisition module occurs. After the pressure and flow data of the step S102 is judged to meet the inspiratory action standard, it enters the step S103 for execution.
然后执行步骤S104，接收包括制氧机工作状态M的反馈信息，所述反馈信息与所述控制指令相对应。本领域技术人员理解，当制氧机收到呼吸机传来的控制命令后通过输氧管发送氧气到面罩的混氧口，然后再通过数据线返回工作状态M给所述呼吸机，由呼吸机判断本次的送氧步骤是否完成并结束此次控制。具体地，将结合图2和后述的具体实施例作进一步地说明，在此不予赘述。Then step S104 is executed to receive feedback information including the working state M of the oxygen generator, the feedback information corresponding to the control instruction. Those skilled in the art understand that when the oxygen concentrator receives the control command from the ventilator, it sends oxygen to the oxygen mixing port of the mask through the oxygen delivery tube, and then returns to the working state M to the ventilator through the data line, and the ventilator Judging whether the current oxygen supply step is completed and ending the control. Specifically, further description will be made in conjunction with FIG. 2 and specific embodiments described later, and details will not be repeated here.
进一步地，根据图1所示的实施例的一个变化例中，优选地，所述步骤S101包括如下步骤(附图中未示出)：Further, according to a variation example of the embodiment shown in FIG. 1 , preferably, the step S101 includes the following steps (not shown in the drawings):
第一步.判断所述呼吸机和/或所述制氧机是否正常工作；The first step. Determine whether the ventilator and/or the oxygen generator are working normally;
第二步.若所述呼吸机和所述制氧机均正常工作，则基于数据获取模块获取所述压力流量数据。Step 2. If both the ventilator and the oxygen concentrator are working normally, then acquire the pressure flow data based on the data acquisition module.
具体地，通过上述步骤第一步，由呼吸机对呼吸机和制氧机系统进行监测，呼吸机通过检测获取的数据信息判断所述呼吸机和/或所述制氧机是否正常工作。更为具体地，所述呼吸机在开机时运行一套自检系统，由所述自检系统对所述呼吸机自身以及所述制氧机的运行状态进行检测。更进一步地，所述呼吸机首先向所述制氧机发送一个控制指令，指令所述制氧机制氧、输氧并接收所述制氧机发送的反馈信息，以检测所述制氧机是否处于正常工作状态。在一个优选例中，若所述呼吸机和所述制氧机均正常工作时，则所述步骤第一步的判断结果是肯定的；否则，则所述步骤第一步的判断结果是否定的。进一步地，若所述步骤第一步的判断结果是肯定的，则执行步骤第二步；否则，则所述呼吸机或者所述制氧机中任一方或双方均处于不正常工作状态，则发出提示信号，提示用户或相关人员进行维护。Specifically, through the first step of the above steps, the ventilator and the oxygen generator system are monitored by the ventilator, and the ventilator judges whether the ventilator and/or the oxygen generator are working normally through the data information obtained through detection. More specifically, the ventilator runs a set of self-inspection system when it is turned on, and the self-inspection system detects the operating status of the ventilator itself and the oxygen generator. Furthermore, the ventilator first sends a control instruction to the oxygen generator, instructs the oxygen generator to deliver oxygen, and receives the feedback information sent by the oxygen generator to detect whether the oxygen generator is in normal working condition. In a preferred example, if both the ventilator and the oxygen generator are working normally, the judgment result of the first step of the step is affirmative; otherwise, the judgment result of the first step of the step is negative of. Further, if the judgment result of the first step of the step is affirmative, the second step of the step is performed; otherwise, either or both of the ventilator or the oxygen generator are in an abnormal working state, then Send a prompt signal to prompt the user or relevant personnel to perform maintenance.
优选地，在所述步骤第二步中，基于数据获取模块获取所述压力流量数据并根据图1所示的具体实施例进行接下来的步骤，本领域技术人员可以参考上述图1所示实施例中所述步骤S101、所述步骤S102、所述步骤S103以及所述步骤S104，在此不予赘述。Preferably, in the second step of the step, the data acquisition module acquires the pressure and flow data and performs the next steps according to the specific embodiment shown in FIG. 1 . Those skilled in the art can refer to the above-mentioned implementation shown in FIG. 1 The step S101, the step S102, the step S103, and the step S104 in the example are not repeated here.
优选地，若所述呼吸机或所述制氧机中任意一个或两个都没有正常工作，则不执行上述步骤第二步。此时，可以自动或人工设置停止整个装置系统的运行并对所述呼吸机和制氧机进行检查，重启设备，再次通过上述步骤第一步确保所述呼吸机和制氧机均正常工作时，执行后续步骤。在一个优选例中，当所述呼吸机检测发现自身和/或所述制氧机处于异常工作状态时，发出提示音提示用户相应设备处于异常工作状态，并基于用户操作重启设备以重新执行所述步骤第一步。Preferably, if any one or both of the ventilator or the oxygen generator is not working normally, the second step of the above step is not performed. At this time, it is possible to automatically or manually set to stop the operation of the entire device system and check the ventilator and oxygen generator, restart the equipment, and go through the first step of the above steps again to ensure that the ventilator and oxygen generator are working normally. , perform the next steps. In a preferred example, when the ventilator detects that itself and/or the oxygen generator is in an abnormal working state, it sends out a prompt sound to remind the user that the corresponding device is in an abnormal working state, and restarts the device based on the user operation to re-execute the operation.

在本实施例的一个变化例中，所述步骤S102中所述数据获取模块还设置在与所述导气管相连通的呼吸机面罩等用户进行呼吸动作时所产生的气体流量的必经路径上，这同样能获得本发明技术方案所需的气体压力数据或者气体流量数据。In a variation of this embodiment, the data acquisition module in the step S102 is also set on the necessary path of the gas flow generated when the user performs a breathing action, such as a ventilator mask communicated with the airway tube , which can also obtain the gas pressure data or gas flow data required by the technical solution of the present invention.
在本实施例的又一个变化例中，所述步骤S102中还基于所述压力传感模块两端的气压差判断用户当前是否在进行吸气动作，例如，所述呼吸机实时监测导气管内气体流经压力传感模块靠近呼吸机一端A以及靠近用户肺部一端B时的压力数据变化，当用户吸气时，气体流量依次从所述A端到B端再流向用户肺部，此时，所述压力传感模块B端监测到的气压值小于所述压力传感模块A端的气压值；相应地，当用户呼气时，气体流量从人体先通过所述压力传感模块B端再到A端后排出体外，此时，所述压力传感模块B端的气压大于所述压力传感模块A端的气压。通过预先设定所述传感模块A端气压大于所述压力传感模块B端气压时，所述气压差为正值，反之则为负值，通过判断所述气压差的正负值判断用户当前是否进行吸气动作，当所述气压差为正值时，表明用户当前进行吸气动作。In yet another variation of this embodiment, in step S102, it is also judged based on the air pressure difference between the two ends of the pressure sensing module whether the user is currently inhaling, for example, the ventilator monitors the gas in the airway in real time. The pressure data changes when the pressure sensing module is close to the end A of the ventilator and the end B close to the user's lungs. When the user inhales, the gas flow sequentially flows from the A end to the B end to the user's lungs. At this time, The air pressure value monitored by end B of the pressure sensing module is smaller than the air pressure value at end A of the pressure sensing module; correspondingly, when the user exhales, the gas flow from the human body first passes through end B of the pressure sensing module and then to After the end A is discharged from the body, at this time, the air pressure at the B end of the pressure sensing module is greater than the air pressure at the A end of the pressure sensing module. By presetting the air pressure at the end A of the sensing module is greater than the air pressure at the end B of the pressure sensing module, the air pressure difference is a positive value, otherwise it is a negative value, and the user can be judged by judging the positive or negative value of the air pressure difference Whether an inhalation action is currently being performed, and when the air pressure difference is a positive value, it indicates that the user is currently performing an inhalation action.
在本实施例的又一个变化例中，所述步骤S103中所述呼吸机仅向所述制氧机发送输氧的控制指令，本领域技术人员理解，用户在协同使用所述呼吸机和所述制氧机时，所述制氧机在开机启动后自动制氧，制氧后处于待命状态，所述呼吸机确定用户当前正进行吸气动作后同时向所述制氧机发送输氧的控制指令，所述输氧的控制指令包括输送的氧气浓度、输氧量以及输送氧气的速度等，具体地，所述输氧的控制指令根据用户目前吸气动作持续的时间长度、呼吸深度进行调节，使得所述制氧机能够基于所述控制指令将制得的氧气经由导气管输送到用户面罩的混氧口，实现在用户吸气相早期阶段向用户送氧的技术目的。In yet another variation of this embodiment, the ventilator in step S103 only sends oxygen delivery control commands to the oxygen concentrator. When using an oxygen generator, the oxygen generator automatically generates oxygen after starting up, and is in a standby state after oxygen generation. The ventilator determines that the user is currently performing an inhalation action and sends an oxygen delivery control command to the oxygen generator at the same time. , the control instruction for oxygen delivery includes the concentration of oxygen delivered, the amount of oxygen delivery, and the speed of oxygen delivery, etc. Specifically, the control instruction for oxygen delivery is adjusted according to the duration of the user's current inhalation action and the depth of breathing, so that the The oxygen concentrator can deliver the prepared oxygen to the oxygen mixing port of the user's mask through the airway tube based on the control instruction, so as to realize the technical purpose of sending oxygen to the user in the early stage of the user's inhalation phase.

When the obtained oxygen fills the storage area, the oxygen concentrator stops oxygen production and is in a standby state; when the ventilator judges that the user is currently inhaling, the oxygen concentrator will The oxygen stored in the storage area is delivered to the oxygen mixing port of the user's face mask. After each inhalation phase, the oxygen generator discharges a certain amount of oxygen to the user according to the oxygen delivery instruction, and the oxygen generator continues to generate oxygen After the storage area is filled, the oxygen production is stopped and the standby state is entered again.
在另一个优选地变化例中，所述制氧机在用户每次吸气过程中向用户输送完一定量的氧气后并不立即再次制氧，而是继续处于待命状态，直到所述存储区域中氧气全部用完后才再次制氧并充满所述存储区域。更为优选地，在其他的具体实施例中，可以在所述存储区域设置相应的阀值，例如，所述阈值为制氧机氧气存储区域容量的1/2、1/3或其他数值，当所述存储区域剩余的氧气量低于所述阀值时制氧机再开始制氧。本领域技术人员理解，所述呼吸机向所述制氧机发送制氧和/或输氧指令时还可以更多的实施方式，例如，所述呼吸机在用户进行吸气动作时发送输氧指令，在用户进行呼气动作时向所述制氧机发送制氧指令，所述制氧指令的制氧量与所述输氧指令的输氧量相对应。In another preferred variation, the oxygen generator does not generate oxygen again immediately after delivering a certain amount of oxygen to the user during each inhalation process of the user, but continues to be in a standby state until the storage area Oxygen is produced again and filled with the storage area only after all the oxygen in the storage tank is used up. More preferably, in other specific embodiments, a corresponding threshold can be set in the storage area, for example, the threshold is 1/2, 1/3 or other values of the capacity of the oxygen storage area of the oxygen generator, When the amount of remaining oxygen in the storage area is lower than the threshold value, the oxygen generator starts to produce oxygen again. Those skilled in the art understand that when the ventilator sends oxygen generation and/or oxygen delivery instructions to the oxygen concentrator, there may be more implementations, for example, the ventilator sends an oxygen delivery instruction when the user performs an inhalation action, An oxygen production instruction is sent to the oxygen generator when the user performs an exhalation action, and the oxygen production amount of the oxygen generation instruction corresponds to the oxygen delivery amount of the oxygen delivery instruction.
本领域技术人员理解，本实施例所述技术方案通过所述呼吸机直接控制所述制氧机的供氧触发，有效的解决了呼吸机与制氧机的同步性，基于所述数据获取模块对用户呼吸状态的实时监控，确保所述制氧机在用户每次吸气时相的较早期都能准确地向用户给予氧气，并且制氧机的这一送氧过程不会对所述呼吸机的人机同步性造成任何影响，从而有效解决了呼吸机与制氧机无法同步配合使用的技术问题，给用户特别是慢性呼吸衰竭患者的日常使用提供了便利性，极大的优化了用户体验，提高了患者的治疗医从性以及生活质量。Those skilled in the art understand that the technical solution described in this embodiment directly controls the oxygen supply trigger of the oxygen generator through the ventilator, effectively solving the synchronization between the ventilator and the oxygen generator, based on the data acquisition module The real-time monitoring of the breathing state of the user ensures that the oxygen concentrator can accurately supply oxygen to the user in the early phase of each inhalation phase of the user, and the oxygen supply process of the oxygen concentrator will not affect the breathing process of the user.

图2示出根据本发明的第二实施例的，一种提高无创通气时氧气有效利用率的控制方法的流程图，具体地，在本实施例中，首先执行步骤S201，获取用户呼吸时产生的压力流量数据，所述压力流量数据可以是用户呼吸时流经管道的气道压力大小、方向以及气道流量大小、方向信息。进一步地，本领域技术人员可以参考上述图1所述步骤S101，在此不予赘述。Fig. 2 shows a flow chart of a control method for improving the effective utilization rate of oxygen during non-invasive ventilation according to the second embodiment of the present invention. Specifically, in this embodiment, step S201 is first performed to obtain the Pressure flow data, the pressure flow data may be the magnitude and direction of the airway pressure flowing through the pipeline when the user breathes, and the magnitude and direction information of the airway flow. Further, those skilled in the art may refer to step S101 described above in FIG. 1 , which will not be repeated here.
然后执行步骤S202，基于所述压力流量数据判断用户是否在进行吸气动作，具体地，所述数据获取模块能将对应的压力流量数据信息传输给呼吸机中相应处理模块，使得所述呼吸机接收来自数据获取模块的数据信息并进行分析，从而判断出用户在该特定时刻是否处于吸气状态。更为具体地，可以参考上述图1所示实施例中所述步骤S102，在此不予赘述。若所述步骤S202的判断结果是肯定的，则接下来执行步骤S203，向所述制氧机发送制氧和/或输氧的控制指令。具体地，所述控制指令由呼吸机通过数据线发送给制氧机，包括制氧和输氧两项内容。更为具体地，所述控制指令还可以设定参数调控制氧和输氧的氧气量大小。更进一步地，本领域技术人员可以参考上述图1所示实施例中所述步骤S103，在此不予赘述。若所述步骤S202的判断结果是否定的，即用户当前并未进行吸气动作，则接下来重新进入步骤S201执行。Then step S202 is executed to determine whether the user is inhaling based on the pressure and flow data. Specifically, the data acquisition module can transmit the corresponding pressure and flow data information to the corresponding processing module in the ventilator, so that the ventilator Receive and analyze the data information from the data acquisition module, so as to determine whether the user is in an inhalation state at the specific moment. More specifically, reference may be made to step S102 in the above embodiment shown in FIG. 1 , which will not be repeated here. If the judgment result of the step S202 is affirmative, step S203 is executed next to send a control instruction of oxygen generation and/or oxygen delivery to the oxygen generator. Specifically, the control instruction is sent from the ventilator to the oxygen generator through the data line, including oxygen production and oxygen delivery. More specifically, the control instruction can also set parameters to adjust the amount of oxygen for oxygen control and oxygen delivery. Furthermore, those skilled in the art may refer to step S103 in the above embodiment shown in FIG. 1 , which will not be repeated here. If the judgment result of the step S202 is negative, that is, the user is not currently performing an inhalation action, then re-enter the step S201 for execution.
然后执行步骤S204，接收包括制氧机工作状态M的反馈信息，所述反馈信息与所述控制指令相对应，本领域技术人员理解，当制氧机收到呼吸机传来的控制命令后通过输氧管发送氧气到面罩的混氧口，然后再通过数据线返回工作状态M给所述呼吸机，由呼吸机判断当此的制氧并发送是否完成。具体地，所述反馈信息主要包括制氧机根据所述控制指令进行的工作状态M，例如，是否制氧完成、输氧完成或者制氧/输氧协同完成，更进一步地，所述工作状态M还包括所述制氧机的耗电量、工作时长、与所述控制指令相对应的制氧量、输氧量等信息。Then step S204 is executed to receive the feedback information including the working state M of the oxygen generator. The feedback information corresponds to the control command. Those skilled in the art understand that when the oxygen generator receives the control command from the ventilator, it passes The oxygen delivery tube sends oxygen to the oxygen mixing port of the face mask, and then returns to the working state M to the ventilator through the data line, and the ventilator judges whether the oxygen generation and sending are completed at this time. Specifically, the feedback information mainly includes the working state M of the oxygen generator according to the control instruction, for example, whether the oxygen production is completed, the oxygen delivery is completed, or the oxygen production/oxygen delivery is coordinated. Further, the working state M is also It includes information such as the power consumption of the oxygen generator, the working hours, the amount of oxygen production corresponding to the control command, and the amount of oxygen delivered.

Specifically, the judgment process is completed by the control device installed on the ventilator according to the specific content of the control instruction. Accordingly, it is judged Whether this oxygen delivery is completed includes different results. Specifically, when the control instruction only includes any one of oxygen production or oxygen delivery, as long as it corresponds to the content of the control instruction, it is also judged that this oxygen delivery is completed, thereby ending this session. The control process continues to execute the control process at the next moment or ends the use. Further, if the judgment result is that the oxygen delivery is not completed, return to step S203, and repeatedly execute the oxygen generation and/or oxygen delivery steps based on the working state M. For example, if the ventilator judges that the oxygen delivery has not been completed according to the feedback information obtained by the oxygen generator during the execution of the oxygen generation control command, the oxygen generator continues to perform the oxygen generation step. If the feedback information obtained by the oxygen generator during the execution of the oxygen delivery control command is determined by the ventilator to determine that the oxygen delivery has not been completed, the oxygen generator continues to perform the oxygen delivery step. In addition, if the feedback information obtained by the oxygen generator during the execution of the control command of oxygen generation and oxygen delivery is judged by the ventilator that the oxygen delivery has not been completed, the oxygen generator will continue to perform the steps of oxygen generation and oxygen delivery.

The ventilator is connected to the oxygen generator through a data line, and the data line is used to transmit the control signal of the ventilator to the oxygen generator and the feedback signal sent by the oxygen generator to the non-invasive ventilator. The machine and the oxygen concentrator are respectively connected to the mannequin breathing mask in the first simulation unit through an airway tube, the oxygen concentrator transmits oxygen to the user through the oxygen tube, and the noninvasive ventilator assists the user to breathe through the airway tube. In one application scenario, the first simulation unit simulates the inhalation action of the human body, the human body model is in the inhalation state, and the control device 4 shown in FIG. 3 judges the The first simulation unit is performing an inhalation action, and the ventilator sends corresponding instructions to the oxygen generator, and the oxygen generator receives the instructions and successfully produces and delivers oxygen, thereby sending the working status information of successful oxygen production and oxygen delivery Feedback to the control device to complete this step and proceed to the next cycle; in another application scenario, the oxygen generator has an oxygen generation error or successfully generates oxygen but fails to deliver oxygen. In this case, the oxygen generator According to the specific embodiment shown in Fig. 1 or Fig. 2, the machine performs oxygen production and oxygen delivery again and feeds back the corresponding working status information to the control device 4 until the oxygen production and oxygen delivery steps are successfully completed during this inhalation process.
