Description

肺量计、吹口装置及其检测方法 技术领域
本发明是有关于肺量计(spirometer)与吹口装置(mouthpiece tube)以及相对应的检测方法，特别是有关于将呼气与吸气时的气体流动转换为超音波信号以进行侦测与分析的肺量计、吹口装置与检测方法。
背景技术
目前市面上常见的肺量计是以塑胶阻抗压力式以及涡轮式为主。前者是通过呼吸时流经肺量计的气体的风压引发肺量计末端或侧边的薄片式感测器的薄片震荡来产生对应的呼气/吸气信号，后者是通过呼吸时流经肺量计的气体的风压带动肺量计内部的扇叶或涡轮并通过测量所产生的电流或用红外线测量扇叶/涡轮的转动来产生对应的呼气/吸气信号。但是现有的肺量计都仍有一些待改善的问题，像是薄片、扇叶与涡轮的运动惯性往往在气体停止流动时还持续运动一段时间而无法即时停止产生呼气/吸气信号，像是薄片、扇叶与涡轮的重量与磨擦等等往往在气体流量低时或是气体流速变化量小时无法准确地产生相对应的呼气/吸气信号，像是薄片、扇叶与涡轮在生产过程的误差以及在运作过程的耗损，往往造成测量品质的偏差与逐渐劣化并且不易校正测量结果。因此，有需要发展新的肺量计。
发明内容
本发明是使用超音波来产生呼气信号及/或吸气信号，亦即是利用超音波产生装置与超音波侦测装置等来取代现有肺量计所使用的薄片、扇叶与涡轮等等。借由将呼气及/或吸气时的气体流经放置在接口装置的超音波产生装置(像是静音笛(silent whistle)与高尔顿笛(Galton’s whistle))可以产生相对应的超音波信号，而后借由分析处理超音波信号便可以得知呼气及/或吸气的气体流量与气体流速等。
本发明提出的接口装置具有一个壳体与一个超音波产生装置。壳体具有开放端并且具有位于壳体侧壁的通气口，而超音波产生装置可以被放置在壳体的不同部位。举例来说，超音波产生装置可以被放置在壳体的开放端，使得气体可以自超音波产生装置的气流入口流经超音波产生装置的气流出口并由壳体的通气口离开。举例来说，超音波产生装置可以放置在壳体侧壁的开口并使得超音波产生装置的气流入口与气流出口分别位于壳体围绕空间的内部与外部，使得气体可依序流经超音波产生装置的气流入口与气流出口而从壳体的开放端离开。借此，呼气与吸气过程的气体流动便 可以分别产生相对应的超音波信号。
本发明提出的肺量计具有可以将通过的气体(像是呼气及/或吸气过程的气体)的气体流动转换为超音波信号的接口装置，也具有可以接收超音波信号的超音波侦测装置(像是麦克风)。肺量计或可以再具有处理装置以将超音波信号转换为与气体流动有关的信号资料(像是气体流速-时间曲线图或气体流量-时间曲线图)，也或可以再具有通信装置(像是无线网络元件或蓝芽元件)以将超音波信号传输到位于肺量计外界的手机或电脑等等来进行超音波信号的分析。此外，肺量计或可以具有一个外壳，而吹口装置可以通过位于外壳上的接环(joint ring)或其他元件被连接到外壳，并且超音波侦测装置、处理装置与通信装置都是或可以位于外壳内部也或可以整合到吹口装置。
本发明提出的检测方法是运用上述肺量计与上述接口装置的方法。首先，使用可以将呼气及/或吸气过程的气体流动转换为超音波信号的肺量计在呼吸功能检测将呼气及/或吸气时的气体流动转换为超音波信号。然后，分析超音波信号以得到呼气及/或吸气的气体流速-时间曲线图或其他信息，并据以产生相对应的呼吸功能参数参数值。
本发明相较于目前常见的塑胶阻抗压力式肺量计以及涡轮式肺量计至少具有数个优点。首先，成本低廉并且易于制作，因为静音笛与高尔顿笛都是现有的商业化产品，并且超音波侦测装置也已是现有技术。其次，由于超音波产生装置可以在气体流动时(或气体流动大于阈值时)便产生超音波而在气体不流动时(或气体流动小于阈值时)便停止产生超音波，相较于现有产品较为灵敏较不会有气体已经不流动了还因为运动惯性持续一段时间产生呼气/吸气信号的问题。再者，由于静音笛与高尔顿笛等超音波产生装置是利用气体流经一个大抵封闭空间时的气体振动来产生超音波，较不会在使用过程中被耗损或是在气体流动较弱时不易振动而使得测量结果失真，特别是若这个大抵封闭空间的大小轮廓是可以调整以校正产生的超音波信号。另外，现有技术所制作的静音笛、高尔顿笛、麦克风与电路等可以达到极高品质与极低损耗，但是薄片、扇叶与涡轮的生产较不易维持高品质也较易在运作过程中磨损。

实现发明的最佳方式
本发明的详细描述将借由下述实施例讨论，这些实施例并非用于限制本发明的范围，而且可适用于其他应用中。图示揭露了一些细节，须理解的是揭露细节可不同于已透露者，除非是明确限制特征的情形。
本发明是通过将呼气及/或吸气时的气体流经超音波产生装置，借以产生与吸气及/或吸气时的气体流动相关的超音波信号，然后借由分析处理超音波信号，像是将持续测量到的超音波信号转换为呼气/吸气时气体的流速-时间曲线图，便可以掌握呼气及/或吸气的状态。亦即可以说是用超音波产生装置与超音波侦测装置来取代业界习知的肺量计(如塑胶阻抗压力式肺量计以及涡轮式肺量计)所使用来测量气体流动的硬件。在此，超音波产生装置与超音波侦测装置都可以利用现有技术来实现。举例来说，业界习知的静音笛与高尔顿笛可以将流动经过的气体转换为超音波信号，并且所产生的超音波信号的强度与流动经过气体的流速相关。举例来说，超音波侦测装置可以使用种种业界习知技术来实现，像是全指向性麦克风、双 指向麦克风、心型指向性麦克风、超新型指向性麦克风与枪型指向麦克风等等。
本发明可以较目前常见的肺量计得到较为灵敏的气体流速-时间曲线图，进而能更精确地与更稳定地测量呼气及/或吸气的状态，这至少是由于超音波产生装置只有在气体流经时才会产生超音波。在得到气体流速-时间曲线图后，如何得到需要的呼吸功能参数数值，例如尖峰吸气流量、第一秒吸气量与用力肺活量等等数值，都可使用现有习知技术来实现。
本发明的一实施例为肺量计，特别是使用可以将气体流动转换为超音波信号的接口装置的肺量计。如图1A所示，肺量计100具有可以将呼气及/或吸气过程的气体流动转换为超音波信号的接口装置110以及可以接收来自接口装置110的超音波信号的超音波侦测装置120(例如，麦克风)。在某些实施例，超音波侦测装置120可整合到接口装置110，亦即接口装置110既可以将流经的气体转换为超音波信号也可以侦测超音波信号。在某些实施例中，如图1B所示，肺量计100具有外壳130，而接口装置110可以通过位于外壳130上的接环(joint ring)或其他元件与外壳130相连接，并且超音波侦测装置120是置于外壳130所围绕的内部空间中。在此，接口装置110是可以自外壳130移除也可以固定在外壳130上，亦即接口装置110是个可更换的元件，像是不同使用者都可以使用其专属的接口装置110。
在某些实施例中，肺量计100具有可将超音波信号转换为与气体流动有关的信号资料的处理装置140，如图1C所示，处理装置140也位于外壳130所围绕的空间内部。在某些实施例，如图1D所示，肺量计100具有通信装置150(像是无线网络元件或蓝芽元件)以将超音波信号传输到外部装置(例如：手机或电脑等等)199来进行超音波信号的分析。换句话说，肺量计100或可以是一个从接收呼气过程及/或吸气过程的气体到分析超音波信号都可以处理的产品，也或可以是只接收呼气及/或吸气的气体并得到相对应超音波信号的产品而将超音波信号的分析处理交由诸如手机或电脑等来处理。
接口装置110的大小与形状等等，特别是其与肺量计100的外壳130相接处的大小与形状等等，都是或可以与业界习知的肺量计所使用的接口装置的大小与形状相同，但也可以视需要有不同的设计。除此之外，由于本发明所提出的肺量计100是使用可以将流经气体的流动状态转换为超音波的接口装置110，在不同的实施例，超音波侦测装置120、处理装置140与通信装置150的任一者都是或可以位于外壳130所围绕空间内部也或可以整合到接口装置110，亦即或可以完全不使用外壳130，本发明并不限制这部分的变化也并未一一图示所有可能的变化。
本发明另一实施例为接口装置200，特别是使用可以将气体流动转换为超音波信号的接口装置200。如图2A所示，本发明提出的接口装置200的基 本构造包含了壳体210与超音波产生装置220，当呼气及/或吸气时的气体流经放置于壳体210的超音波产生装置220时，像是使用者嘴部接触或与接口装置200邻近并进行吸气或吹气作用时，便会产生对应到气体流动状态(如气体流速)的超音波信号。当超音波侦测装置120位于肺量计100的外壳130内部时而接口装置200的壳体210是通过接环等连接到外壳130，壳体210亦可以固定超音波产生装置220与超音波侦测装置120的距离。在不同的实施例，壳体210的尺寸与轮廓等或可以与现有习知肺量计所使用接口装置的尺寸与轮廓相同，特别是壳体210与外壳130相接处的尺寸与轮廓，但也或可与现有习知肺量计所使用接口装置的尺寸与轮廓不相同。
在某些实施例，超音波产生装置220是习知的静音笛或高尔顿笛，如此做的优点是成本低与技术简单，不需要再开发新的装置。现有静音笛与现有高尔顿笛的架构，基本上如图2B所示般，笛壳291的一端为开口端292，并笛壳291的相对另一端是封闭或开放的，其中，笛壳291的相对两端之间为内部空间294，且在此内部空间294的笛壳291侧壁上具有切口端293，而在开口端292与切口端293之间的内部空间294中设置扰流构件295。气体自开口端292流经内部空间294到切口端293的过程中，气体借由扰流构件295造成气流扰动的现象以引发超音波，而且所引发超音波的强度基本上与气体流速相关且所引发超音波的频率基本上与内部空间294的轮廓与尺寸有关。
当使用现有习知的静音笛或高尔顿笛为超音波产生装置220时，壳体210的一端是封闭的(不通风的)而另一端是开放的(可通风的)并且具有位于壳体210侧壁的开口230，而超音波产生装置220被放置在壳体210的不同部位以分别侦测吸气状态或吸气状态。举例来说，如图2C所示，若要侦测呼气(吐气)状态，超音波产生装置220被放置在壳体210的开放端，使得气体可以自超音波产生装置220的开口端292依序流经超音波产生装置220内部空间294的扰流构件295与切口端293并由壳体210的通气口230离开。举例来说，如图2D所示，若要侦测吸气状态，超音波产生装置220被放置在壳体210侧壁的通气口230并使得超音波产生装置220的开口端292与切口端293分别位于壳体210所围绕空间的外部与内部，使得气体可以自超音波产生装置220的开口端292引入，并依序流经音波产生装置220内部空间294的扰流构件295与切口端293，然后经由壳体的210开放端而离开。借此，呼气与吸气过程的气体流动便可以分别经由超音波产生装置220而产生相对应的超音波信号。
本发明的某些实施例为呼吸功能检测方法。这些实施例适用于上述讨论的肺量计与接口装置，并且基本流程可以摘要如图3所示。首先，如步骤方块31所示，准备可以将气体流动转换为超音波信号的肺量计。接着，如 步骤方块32所示，在一段时间持续以肺量计接收使用者呼气及/或吸气的气体并将气体流动转换为超音波信号。然后，如步骤方块33所示，接收与分析超音波信号以得到相对应的呼吸功能参数数值。
举例来说，可以将在这段期间内持续产生的超音波信号转换为呼气或吸气过程气体的流速-时间曲线图，如图4A所定性显示的范例。借此，或可在测量吸气的过程中根据流速极大值或是流速超过阈值与否来判断吸气部分的呼吸功能，也或可以在测量吸气的过程根据在一段时间中的流速变化得到如图4B所定性显示的气体总量-时间曲线图(等于是对流速-时间曲线图做积分处理)并据以判断吸气部分的呼吸功能。进一步地，在检测吐气功能时可以测量气体流速的峰值及/或气体流速高于阈值的时间，而在检测吸气功能时，可以测量在某段时间累积的气流流量及/或在气体流速高于阈值期间累积的气体流量。
必须强调地是由于本发明所使用的超音波产生装置(如静音笛与高尔顿笛)、超音波侦测装置(如种种上述麦克风)与处理装置(可以用集成电路或应用程序执行)都较容易做到高度品质稳定与低度耗损，相对地现有习知肺量计所使用的薄片、扇叶与涡轮等较易耗损、较难稳定生产品质以及较易在气体停止流动后还因为运动惯性而持续产生超音波信号，因此不论是在侦测吸气的状况或是在侦测吸气的状况，本发明使用超音波所得到的流速-时间曲线图与气体总量-时间曲线图的波形会较呈现巨齿状，亦即对气体流动的测量会比较灵敏。特别是由于人的吸气会越吸越少越慢但人的吸气会上下起伏而气体流速不稳定，现有习知肺量计所使用的涡轮、扇叶与塑胶片等在测量吸气时会因为吸气气体的流速起伏变动而不易准确测量，相对地本发明使用超音波测量是只要有气体流动便会产生超音波而且没有气体流动便停止产生超音波，因此使用本发明时的优点更为明显。
本发明提出的肺量计与接口装置也可以与现有的智能型手机进一步地整合。也就是除了使用智能型手机作为肺量计的处理装置之外，本发明的某些未图示的实施例或可以直接将接口装置(含超音波产生装置)与超音波侦测装置二者整合进入智能型手机，或可以将接口装置(含超音波产生装置)与超音波侦测装置整合成可以通过诸如万用串列汇流排(Universal Serial Bus，USB)连接到智能型手机的外接元件(类似通过耳机孔连接到智能型手机的耳机)。当然，在这种状况，需要因应不同麦克风的不同灵敏度以及麦克风与高音波产生装置的距离来调整所使用的演算法，至少调整演算法所使用参数的参数值。
当本发明的超音波产生装置是静音笛或高尔顿笛或其他可调整所产生超音波的频率的硬件时，本发明可固定住静音笛/高尔顿笛所产生的超音波的频率(亦即扰流构件295的位置是固定的)，也可让静音笛/高尔顿笛所产 生的超音波的频率是可以调整的(亦即在扰流构件295的位置是可以改变的)。固定住所产生超音波频率的好处是对于气体流速与气体流量的测量与计算较为简单，所使用演算法中较少需要调整的参数。
根据本发明的另一实施例，参考图5A至图5C所示，本发明提供一种吸口装置500，该吸口装置500包含：壳体510与至少一个超音波产生装置520。其中，壳体510可为圆筒状，且壳体510的一端是吸气口511，另一端为壳体底部512，其中，壳体底部更包含至少一个通道530以容置至少一个超音波产生装置520，通道530可为圆筒状，且通道530具有至少一个通道口531以便与壳体510外部相通，与至少一个通气口514。通气口514是与吸气口511连通以形成壳体510内的气流空间，其中，壳体底部512更包含至少一个沟槽513与至少一个气孔515，且沟槽513是位于壳体底部512而面向吸气口511以便于分隔每个通道530并使每个通道530个别独立而不相通，其气孔515连通吸口装置500外部以额外引入气流，使气流流通阻力降低，气孔515可位于沟槽513上或其他非位于通道530的部位。此外，超音波产生装置520可为管状，超音波产生装置520更包含气流入口521、超音波产生装置底部522、气流出口523与扰流构件525，其中，气流入口521是位于超音波产生装置520的一端以导入气流，超音波产生装置520的另一端是超音波产生装置底部522，气流出口523是位于超音波产生装置520的中间部位，扰流构件525是位于超音波产生装置520之内，并位于气流入口521与气流出口523之间，扰流构件525可为档片，其于超音波产生装置520的内部空间形成狭窄通道以形成气流扰动，并使得气流出口523的空气产生特殊波动。其中，超音波产生装置520容置于通道530内，且气流出口523与通气口514相通以从超音波产生装置520内部导引气体进入壳体510内的气流空间中，其中，从气流入口521导入超音波产生装置520内的气流路径是与从气流出口523导出超音波产生装置520外的气流路径相互正交。
根据本实施例，参考图5A至图5C所示，本发明的吸口装置500的作用如下：首先，提供气流吸力以便从吸口装置500的壳体510内部的气流空间朝向吸气口511导出气体。当气流吸力开始作用后，吸口装置500的外部气体将从至少一个超音波产生装置520的气流入口521引入气流，并依序经由扰流构件525、气流出口523导出超音波气流，并从通气口514导入至壳体510内的气流空间中。此时，可借由超音波侦测装置测量并计算吸气过程的流速极大值或判断流速是否超过阈值以辨别呼吸功能。此外，吸气口511导出气体的方向是与至少一个超音波产生装置520的气流入口521引入气流的方向相互正交。另一方面，由于超音波气流的引流路径经过正交转换方向，因此会产生相当大的流通阻力，所以通过气孔515的设置，可在气流吸力开始作用同时大幅降低气流流通阻力。
根据本发明的再一实施例，参考图6A至图6C所示，本发明提供一种吹口装置600，该吹口装置600包含：壳体610与至少一个超音波产生装置620。其中，壳体610可为圆筒状，且壳体610的一端是入口端611以导引外部气体流入壳体610内部，其另一端则为出口端612，出口端612中间是固定构件630，与至少一个通气口614位于壳体610侧壁，其中，固定构件630更包含至少一个固定通道631，固定通道631更包含固定通道定位部633，且通气口614是连通壳体610外部与固定通道631。超音波产生装置620可为管状，其中，超音波产生装置620更包含气流入口621、超音波产生装置底部622、气流出口623与扰流构件625、定位构件626。其中，气流入口621是位于超音波产生装置620的一端以导入气流，超音波产生装置620的另一端是超音波产生装置底部622，气流出口623是位于超音波产生装置620的中间部位，扰流构件625则位于超音波产生装置620之内，并位于气流入口621与气流出口623之间，扰流构件625可为档片，其形成狭窄口，其中，定位构件626与固定通道定位部633相符以使得超音波产生装置620能轻易的正确构装并容置于固定通道631中，并使气流出口623准确的与通气口614相通以便于从超音波产生装置620内部导出气体离开壳体610内的气流空间，其中，从气流入口621导入超音波产生装置620内的气流路径是与从气流出口623导出超音波产生装置620外的气流路径相互正交。
根据本实施例，参考图6A至图6C所示，本发明的吹口装置600的作用如下：首先，提供气流推力以便从入口端611导入气体至吹口装置600的壳体610内部。当气流推力开始作用后，进入吹口装置600的气体将从至少一个超音波产生装置620的气流入口621导入气流，并依序经由扰流构件625、气流出口623导出超音波气流，并从通气口614导出至壳体610外部。此时，可借由超音波侦测装置测量并计算呼气过程的流速峰值或判断流速超过阈值的时间以辨别呼吸功能。此外，入口端611导入气体的方向是与超音波产生装置620的气流入口621引入气流的方向平行，且入口端611导入气体的方向则与通气口614导出气体的方向正交。
显然地，依照上面实施例中的描述，本发明可能有许多的修正与差异。因此需在其附加的权利请求项的范围内加以理解，除上述详细描述外，本发明还可以广泛地在其他的实施例施行。上述仅为本发明的较佳实施例，并非用以限定本发明的申请专利范围；凡其它未脱离本发明所揭示的精神所完成的等效改变或修饰，均应包含在下述申请专利范围内。

    至少一个通气口位于该壳体侧壁，且该通气口是连通该壳体外部与该固定通道；与
    至少一个超音波产生装置，该超音波产生装置容置于该固定通道中，该超音波产生装置更包含气流入口与气流出口，该气流出口与该通气口相通以从该超音波产生装置的内部导引气体至该壳体外部，借此，该吹口装置借由气流推力的作用从该入口端导入气体至该壳体内部，并使进入该壳体内部的气体从该超音波产生装置的该气流入口导入气流，并从该气流出口导出超音波气流。
  27. 根据权利要求26所述的吹口装置，其特征在于：其中上述的超音波产生装置更包含扰流构件，该扰流构件是位于该超音波产生装置之内，并位于该气流入口与该气流出口之间，以便于该超音波产生装置的内部空间形成狭窄通道。
  28. 根据权利要求26所述的吹口装置，其特征在于：其中上述的气流出口是位于该超音波产生装置的中间部位。
  29. 根据权利要求26所述的吹口装置，其特征在于：其中上述的固定通道更包含固定通道定位部，且该超音波产生装置更包含定位构件，其中，该定位构件与该固定通道定位部相符以使该超音波产生装置能轻易的正确构装并容置于该固定通道中，并使该气流出口准确的与该通气口相通。
  30. 根据权利要求26所述的吹口装置，其特征在于：从该气流入口导入该超音波产生装置内的气流路径是与从该气流出口导出该超音波产生装置外的气流路径相互正交。
  31. 根据权利要求26所述的吹口装置，其特征在于：从该入口端导入气体的方向是与该超音波产生装置的该气流入口引入气流的方向平行，且该入口端导入气体的方向则与该通气口导出气体的方向正交。
