Description

辅助呼吸气雾气体的装置及调节呼吸气雾气体的方法Device for assisting breathing aerosol gas and method for regulating breathing aerosol gas

技术领域 technical field

本发明涉及呼吸辅助装置,尤其涉及的是辅助呼吸气雾气体的装置及调节呼吸气雾气体的方法。 The invention relates to a breathing assistance device, in particular to a device for assisting breathing aerosol gas and a method for regulating breathing aerosol gas.

背景技术 Background technique

气雾吸入治疗是呼吸科的常见治疗方法之一。 Aerosol inhalation therapy is one of the common treatment methods in respiratory department.

气雾吸入治疗时,随气流吸入肺部的气雾气体必须达到小气道才能发挥疗效。但是,呼吸道存在解剖死腔,解剖死腔是指口腔至呼吸性细支气管之间的呼吸道,正常成人的解剖死腔气体容量为140ml,气体容量是指能够容纳的气体体积。吸气时,气体经过解剖死腔后再到达呼吸性细支气管和肺泡,呼气时,解剖死腔内的气体首先呼出,然后,才是来之于细支气管和肺泡的气体。 During aerosol inhalation therapy, the aerosol gas inhaled into the lungs along with the air flow must reach the small airways to exert its curative effect. However, there is an anatomical dead space in the respiratory tract, which refers to the respiratory tract between the oral cavity and the respiratory bronchioles. The gas capacity of the anatomical dead space of a normal adult is 140ml, and the gas capacity refers to the volume of gas that can be accommodated. When inhaling, the gas passes through the anatomical dead space and then reaches the respiratory bronchioles and alveoli. When exhaling, the gas in the anatomical dead space is exhaled first, and then the gas from the bronchioles and alveoli.

然而,在进行气雾吸入治疗时,只有进入细支气管和肺泡并沉积于小气道和肺泡内的气雾药物才能发挥作用。实际气雾吸入治疗时,尚未进入细支气管和肺泡的伴随吸气进入解剖死腔的气雾药物,没有发挥作用就通过呼气被排出,进入细支气管和肺泡的气雾药物比例较少,使气雾吸入治疗效果不能达到最佳化。 However, during aerosol inhalation therapy, only the aerosol drug that enters the bronchioles and alveoli and is deposited in the small airways and alveoli can play a role. In the actual aerosol inhalation treatment, the aerosol drugs that have not yet entered the bronchioles and alveoli and enter the anatomical dead space with inhalation are discharged through exhalation without exerting their effect, and the proportion of aerosol drugs entering the bronchioles and alveoli is relatively small, making the The therapeutic effect of aerosol inhalation cannot be optimized.

由上可知,现有技术中气雾吸入治疗不能保证气雾药物的充分吸收,缺少有效的辅助呼吸气雾气体的装置,因此,现有技术还有待于改进和发展。 It can be seen from the above that the aerosol inhalation treatment in the prior art cannot ensure the full absorption of the aerosol medicine, and there is a lack of an effective device for assisting breathing aerosol gas. Therefore, the prior art still needs to be improved and developed.

具体实施方式 Detailed ways

本发明提供了辅助呼吸气雾气体的装置及调节呼吸气雾气体的方法,为使本发明的目的、技术方案及效果更加清楚、明确,以下参照附图并举实例对本发明进一步详细说明。应当理解,此处所描述的具体实施例仅用以解释本发明,并不用于限定本发明。 The present invention provides a device for assisting breathing aerosol gas and a method for regulating breathing aerosol gas. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

本发明技术方案的设计构思如下:由于只有进入细支气管和肺泡的气雾药物并沉积于小气道和肺泡内才能发挥作用,所以需要确保气雾药物能够伴随吸气进入呼吸道,而且还需要保证呼吸的时长,延长单次呼吸的时间,尽量使呼吸者(人)深呼吸。这样,只需控制吸气及呼气的速度即可。如同本发明最简方案,只需设置三个口,使进气连接口及呼气口较小即可控制吸气及呼气的速度,延长单次呼吸的时间。 The design concept of the technical solution of the present invention is as follows: Since only the aerosol medicine that enters the bronchioles and alveoli and is deposited in the small airways and alveoli can play a role, it is necessary to ensure that the aerosol medicine can enter the respiratory tract with inhalation, and it is also necessary to ensure that the breathing The length of time, prolong the time of a single breath, try to make the breather (person) take a deep breath. In this way, you only need to control the speed of inhalation and exhalation. Like the simplest solution of the present invention, only three ports need to be provided, so that the air intake connection port and the exhalation port are smaller to control the speed of inhalation and exhalation, and prolong the time of a single breath.

根据上述构思,本发明提供了最简的辅助呼吸气雾气体的装置,具体如图1所示,本发明所述的辅助呼吸气雾气体的装置结构图,包括:管道400,以及设置在管道400上的用于连接气雾喷射装置500的进气连接口100、用于排出呼吸道气体的呼气口200及用于与呼吸道接触交换的接触交换口300。需要说明的是,呼气口不但能够进气还能排出气,进气连接口用于气雾气体的进入(也可用于空气的进入),呼气口较小时,呼出的气体不能及时的排出,系数的气体不能及时的获取,这样就延长了单次呼吸的时长,延长雾气药物在体内的停留时间。同时,呼气时管道产生呼气末正压,有利于存在内源性呼气末正压的肺泡气体充分呼气,呼气结束时,管道压力下降,随之吸气产生管道负压,通过人工按压气雾喷射装置,使气雾气体进入管道,气雾气体顺着吸气气流进入肺部,在呼气口大小适当的情况下,可保证吸气流速合适和吸气时间足够长,这样就能将进入管道的气雾气体吸入肺部,保证气雾气体(气雾药物)被充分吸入肺部,发挥疗效。 According to the above concept, the present invention provides the simplest device for assisting breathing aerosol gas, specifically as shown in Figure 1, the structural diagram of the device for assisting breathing aerosol gas according to the present invention, including: a pipeline 400, and The air intake connection port 100 on the 400 is used to connect the aerosol injection device 500 , the exhalation port 200 is used to discharge air from the respiratory tract, and the contact exchange port 300 is used to contact and exchange with the respiratory tract. It should be noted that the exhalation port can not only take in air but also exhale it. The air intake connection port is used for the entry of aerosol gas (also can be used for the entry of air). When the exhalation port is small, the exhaled gas cannot be discharged in time. , the coefficient of gas cannot be obtained in time, which prolongs the duration of a single breath and prolongs the residence time of mist medicine in the body. At the same time, when exhaling, the pipeline generates positive end-expiratory pressure, which is conducive to the full exhalation of alveolar gas with endogenous positive end-expiratory pressure. Manually press the aerosol injection device to make the aerosol gas enter the pipeline, and the aerosol gas enters the lungs along the inhalation airflow. When the size of the exhalation port is appropriate, the inhalation flow rate can be ensured and the inhalation time is long enough. The aerosol gas entering the pipeline can be inhaled into the lungs, ensuring that the aerosol gas (aerosol medicine) is fully inhaled into the lungs and exerts a curative effect.

本发明提供的最简的辅助呼吸气雾气体的装置并不能调节呼气阻力,也不能调节喷射的气雾气体与非气雾气体比例及吸气速度,更不能对气雾喷射装置喷射的气雾气体进行观察,为此,本发明还提供了一较佳方案。具体如图2所示。 The simplest device for assisting respiration of aerosol gas provided by the present invention cannot adjust the exhalation resistance, nor can it adjust the ratio of sprayed aerosol gas to non-aerosol gas and the inhalation speed, nor can it adjust the gas sprayed by the aerosol spray device. The mist gas is observed, and for this reason, the present invention also provides a better solution. Specifically as shown in Figure 2.

请参见图2,本发明所述的辅助呼吸气雾气体的装置,包括: Please refer to Fig. 2, the device for assisting breathing aerosol gas according to the present invention, including:

管道400以及设置在管道400上的用于连接气雾喷射装置的进气连接口100、用于排出呼吸道气体的呼气口200及用于与呼吸道接触交换气体的接触交换口300; The pipeline 400 and the inlet connection port 100 for connecting the aerosol injection device, the exhalation port 200 for exhausting the respiratory tract gas and the contact exchange port 300 for contacting and exchanging gas with the respiratory tract arranged on the pipeline 400;

Resistance, so that the device for assisting respiration of aerosol gas can be applied to different respirators, and the best exhalation resistance can be set.

吸气限流器106是在进气连接口进气的基础上增设的,主要是在进气连接口连接气雾喷射装置时,调节进气连接口进气量与气雾喷射装置喷射的气雾气体量的比例。由于呼吸者的情况不尽相同,增设吸气限流器106,可使辅助呼吸气雾气体的装置适用于不同的呼吸者及同一呼吸者不同的治疗期,而且吸气限流器是通过调节空气的进气量大小调节上述比例的。所述的吸气限流器106为单向吸气限流器,只允许气体进入,不允许气体流出。 Inhalation flow restrictor 106 is added on the basis of the air intake of the air intake connection port, mainly to adjust the air intake amount of the air intake connection port and the air sprayed by the aerosol spray device when the air intake connection port is connected to the air mist injection device. The proportion of fog volume. Because the situation of the respirator is not the same, adding an inspiratory flow restrictor 106 can make the device for assisting breathing aerosol gas suitable for different respirators and different treatment periods of the same respirator, and the inspiratory flow restrictor is adjusted The intake volume of air is adjusted according to the above ratio. The inspiratory flow restrictor 106 is a one-way inspiratory flow restrictor, which only allows gas to enter and does not allow gas to flow out.

There are many ways to realize the trigger unit 105. If the trigger unit is a sensor, such as a pressure sensor, which can sense the pipeline pressure, the aerosol spray device is provided with a response mechanism, and the response mechanism controls the air mist when it receives the signal from the sensor. Mist spray device sprays.

本发明所述的辅助呼吸气雾气体的装置,优选的,还包括:设置在进气连接口的气雾喷射装置500。请参见图3,图3是本发明所述的气雾喷射装置的结构剖面图。如图3所示,所述气雾喷射装置设置有气雾喷嘴203及盛放有液体的气囊202。需要说明的是,气雾喷射装置可以是作为所述辅助呼吸气雾气体的装置的组成部分。 The device for assisting respiration of aerosol gas according to the present invention preferably further includes: an aerosol injection device 500 arranged at the air inlet connection port. Please refer to FIG. 3 . FIG. 3 is a structural sectional view of the aerosol injection device of the present invention. As shown in FIG. 3 , the aerosol injection device is provided with an aerosol nozzle 203 and an airbag 202 filled with liquid. It should be noted that the aerosol injection device may be a component of the device for assisting breathing with aerosol gas.

请参见图4,图4是本发明所述的辅助呼吸气雾气体的装置使用时的气体流向图。在图4中,包含了两个状态: Please refer to FIG. 4 . FIG. 4 is a gas flow diagram of the breathing aid aerosol gas device according to the present invention in use. In Figure 4, two states are included:

吸气状态的气体流向为:吸气时,空气沿方向303进入所述辅助呼吸气雾气体的装置,且气雾喷射装置将气雾气体沿方向304喷射到所述辅助呼吸气雾气体的装置内,这样,呼吸者就能在接触交换口吸入气体,接触交换口的气体流向由内向外(相对辅助呼吸气雾气体的装置而言),沿方向301的左箭头所示方向。 The gas flow direction in the inhalation state is: when inhaling, air enters the device for assisting breathing aerosol gas along direction 303, and the aerosol injection device sprays aerosol gas along direction 304 to the device for assisting breathing aerosol gas In this way, the respirator can inhale gas at the contact exchange port, and the gas at the contact exchange port flows from inside to outside (relative to the device for assisting breathing aerosol gas), along the direction shown by the left arrow in direction 301.

呼气状态的气体流向为:呼气时,来自呼吸道的气体首先由接触交换口进入所述辅助呼吸气雾气体的装置,接触交换口的气体流向由外向内(相对辅助呼吸气雾气体的装置而言),沿方向301的右箭头所示方向,然后经由呼气口沿方向302排出。 The gas flow direction in the exhalation state is: when exhaling, the gas from the respiratory tract first enters the device for assisting breathing aerosol gas through the contact exchange port, and the gas contacting the exchange port flows from outside to inside (relative to the device for assisting breathing aerosol gas) ), in the direction indicated by the right arrow in direction 301, and then exhaled in direction 302 through the exhalation port.

所述的辅助呼吸气雾气体的装置,优选的,还包括:用于实时获取呼吸者吸入的气体体积值的呼吸量检测单元。获取呼吸者吸入的气体体积值后,能够根据所述气体体积值及时控制气雾喷射装置停止喷射气雾,减少气雾进入解剖死腔,这样就可以节省气雾气体(气雾药物)。 The device for assisting respiration of aerosol gas preferably further includes: a respiration volume detection unit for obtaining the volume value of the gas inhaled by the respirator in real time. After obtaining the gas volume value inhaled by the respirator, the aerosol injection device can be controlled in time to stop spraying aerosol according to the gas volume value, reducing the aerosol entering into the anatomical dead space, thus saving aerosol gas (aerosol medicine).

所述的辅助呼吸气雾气体的装置,优选的,还包括:用于当呼吸者吸入一定量体积的气体后控制气雾喷射装置停止喷射气雾的控制及终止喷射单元。一定量体积是指呼吸者正常呼吸的气体体积减去解剖死腔气体容量,如正常成人的解剖死腔气体容量为140ml,如果在用户吸入量尚有140ml前停止气雾喷射,则在最后进入的140ml气雾气体会全部停留在解剖死腔内,这样就不会浪费气雾气体。 The device for assisting respiration of aerosol gas preferably further includes: a control and termination unit for controlling the aerosol injection device to stop spraying aerosol after the breather inhales a certain volume of gas. A certain volume refers to the gas volume of the respirator’s normal breathing minus the gas volume of the anatomical dead space. For example, the gas volume of the anatomical dead space of a normal adult is 140ml. The 140ml of aerosol gas will all stay in the anatomical dead space, so that the aerosol gas will not be wasted.

请参见图5,图5是本发明所述的调节呼吸气雾气体的方法流程图。如图5所示,所述的调节呼吸气雾气体的方法,包括以下步骤: Please refer to FIG. 5 , which is a flow chart of the method for regulating respiratory aerosol gas according to the present invention. As shown in Figure 5, the described method for regulating breathing aerosol gas comprises the following steps:

步骤501、当呼吸者吸气时,控制气雾喷射装置喷射气雾,并通过调节吸气限流器控制吸气流速,使管道产生负压;患者吸气时,管道内的压力降低,打开气雾喷射装置喷药,使喷出的气雾顺着吸气气流被吸入呼吸道。吸气时使管道产生负压,调节吸气限流器,保证吸气流速合适和吸气时间足够长,优先将开放进入管道的气雾气体吸入肺部,保证气雾药物被充分吸入肺部,发挥疗效。 Step 501. When the patient inhales, control the aerosol injection device to spray aerosol, and control the inspiratory flow rate by adjusting the inspiratory flow restrictor, so that the pipeline generates negative pressure; when the patient inhales, the pressure in the pipeline decreases, and the open The aerosol injection device sprays medicine, so that the sprayed aerosol is inhaled into the respiratory tract along the inspiratory airflow. Make the pipeline generate negative pressure when inhaling, adjust the inspiratory flow restrictor to ensure that the inspiratory flow rate is appropriate and the inspiratory time is long enough, and the aerosol gas that enters the pipeline is preferentially inhaled into the lungs to ensure that the aerosol drug is fully inhaled into the lungs , to play a curative effect.

步骤502、在呼吸者吸入一定量体积的气体后控制气雾喷射装置停止喷射气雾;一定量体积是指呼吸者正常呼吸的气体体积减去解剖死腔气体容量,如正常成人的解剖死腔气体容量为140ml,如果在用户吸入量尚有140ml前停止气雾喷射,则在最后进入的140ml气雾气体会全部停留在解剖死腔内,这样就不会浪费气雾气体。 Step 502, control the aerosol injection device to stop spraying aerosol after the respirator inhales a certain volume of gas; the certain volume refers to the gas volume of the respirator's normal breathing minus the gas volume of the anatomical dead space, such as the anatomical dead space of a normal adult The gas capacity is 140ml. If the aerosol injection is stopped before the user inhales 140ml, the last 140ml of aerosol gas will stay in the anatomical dead space, so that the aerosol gas will not be wasted.

步骤503、当呼吸者呼气时,通过单向呼气阀调节呼气阻力,使管道产生呼气末正压。患者呼气时,管道内的压力压力升高,打开呼气单向阀进行呼气,呼气阀上的阻力开关可以调节呼气阻力,使管道产生一定的压力,根据每个患者的感觉,可以找到一个合适的压力值。 Step 503 , when the respirator exhales, the exhalation resistance is adjusted through the one-way exhalation valve, so that the pipeline generates a positive end-expiratory pressure. When the patient exhales, the pressure in the pipeline rises, and the exhalation one-way valve is opened to exhale. The resistance switch on the exhalation valve can adjust the exhalation resistance to make the pipeline generate a certain pressure.
