During sleep, the patient's fingers may move involuntarily, which may cause the sensor to fall off and shift, thereby affecting the measurement.

Description

多节指套式探头 技术领域
本发明涉及医疗器械领域，尤其涉及一种多节指套式探头。
背景技术
血氧饱和度是临床关键生理参数之一。目前一般采用应用光电原理的血氧饱和度测量仪来进行测量，其中，血氧探头即血氧饱和度传感器是血氧饱和度测量仪的核心部件。
使用血氧饱和度测量仪时，常见的测量部位是手指，血氧探头常见的使用部位是手指，针对手指部位使用的传感器一般均为透射式，即发光管与接收管分别接触指甲及指腹，光发光管发出的光透过指甲后在指腹侧被接收管接收。在另外一些部位进行血氧饱和度测量时，也有采用反射式传感器的。由于手指上血流丰富，因此，临床上使用最多的测量部位是手指，该类用于手指测量的血氧探头按组成结构及使用方法可以分为以下几种：指夹式血氧探头(如CN201079393Y所示)，指套式血氧探头(如CN201098122Y所示)，包裹式血氧探头(如CN301554262所示)，粘贴式血氧探头(如CN203169184所示)。
其中，指套式血氧探头通过将发光及接收元件固定在硅胶套中，使用时将硅胶套套在手指上进行测量。如CN201333039Y中图1所示，一种现有的指套式血氧探头为扁平状，上下较窄，两侧宽大，使用时只在手指的指背与指腹处接触手指，在手指两侧面留有很大的间隙，之所以这样设计，一是为了适应医院里各种病人的不同形状不同粗细的手指，使他们都能佩戴而不需要很多尺寸及款式，因此，目前市场上只有大，中，小三种款式即适应了所有成年人；二是两侧面留有很大的间隙保证了昏迷或意识障碍的病人使用时不会出现由于血氧探头太紧导致手指远端血液供应障碍而没有觉察的事故。如CN201333039Y中图5所示，另一现有的指套式血氧探头根据大部分人的手指一般是第一指节(末端指节)比第二指节(中指节)细且逐渐由细变粗的特点，容纳手指的内腔由指尖向后呈V字形变大，由于发光管及接收管位于第一指节的指甲处，因此，该处壁厚比较厚。同时，为加强指套对手指的抓握力， 如CN2785542Y图1中150-A及150-B所示，往往会在指套的开口处(手指伸入处)边沿增加厚度，设有唇边或凸起，或如CN103481443中图1所示，在指套的左右两侧边增加厚度以加强夹持力。
但以上这些设计也会造成以下问题。一是现有的指套式血氧探头在使用时容易脱落，原因是，在同样的接触力下，现有的指套式血氧探头只在手指的指背与指腹处接触手指，两侧留有很大的间隙，手指可以在指套内左右方向移动，同时由于接触面积小，手指与探头间摩擦阻力小，容易脱落；二是如CN201333039Y中图5及CN2785542Y图1中150-A所示，现有的指套式血氧探头与手指接触面积小，为保证不容易脱落，指套的整体或局部设计得比较厚或者材料比较硬从而能产生足够的弹力或挤压力，因此对手指的压力大，造成佩戴时舒适性差；三是扁平形状会挤压所佩戴的手指左右相临的两个手指，导致佩戴时舒适性差，不时的挤压也会导致指套活动而脱落；四是现有的指套式血氧探头整体为一节，为不分节的结构，与分节的手指不匹配，由于手指的指背及指腹侧被指套压着，相当于手指被指套固定在伸直的位置，因此手指不容易弯曲，而经验告诉我们，伸直的手指与弯曲的手指相比较，更容易从指套内脱落；五是如CN201333039Y图1中107A所示，由于发光及接收元件的走线管路主要分布在硅胶套的扁平状的两侧，因此走线处需要加厚隆起，同时，内部的走线为金属导线，与硅胶相比，比较硬，因此，佩戴时相对较硬的隆起会压迫相临两侧手指，导致舒适性差；六是现有的指套式血氧探头只在手指的后端有开口用以手指进入指套，在前端有开口用以指甲伸出但该开口不大，而两侧虽然与手指间留有间隔，但间隙内空气流动性差，使用时间长时会有汗水留在与指套接触的手指上，舒适性差，也容易造成脱落；七是现有的指套整体为一节，设计及使用时并不能区分两个指节，指套对手指的第一指节与第二指节的压力相同或相似，而发光管及接收管往往位于第一指节，如果为防止脱落而加强整个指套对手指的压力，则可能导致第一指节血液供应减弱，影响测量；八是现有的指套内腔为V字形，前端小，后端大，与手指形状相似，这样的设计看起来符合人体工程学原理，但实际上由于每个人的手指形状各不相同，两个指节粗细变化并不一致，因此，有可能有些人第二指节相对较细，这样，如果用现有的指套，会造成指套对第一指节夹持力比较大，对第二指节夹持力比较小，既容易脱落，又受力不均匀 而舒适性差。
睡眠呼吸监测是对有睡眠呼吸暂停综合症的病人进行诊断，监护及治疗必不可少的措施。睡眠呼吸监测病人往往需要在睡眠中进行监测，有时需要在家庭中进行测量，因此，对于使用何种血氧探头提出了很高的要求。睡眠时病人手指可能会不自主地活动，有可能造成传感器脱落，移位，从而影响测量。如果在家庭中应用，由于没有医生、护士在身边的指导，如何方便可靠地安放是测量成败的关键。现有的指套式血氧探头虽然可以重复使用，但固定在手指上不可靠，容易在睡眠时脱落，使用时舒适性差，有待改进。

具体实施方式
为更进一步阐述本发明所采取的技术手段及其效果，以下结合本发明的 优选实施例及其附图进行详细描述。
请参阅图1至图7，本发明提供一种多节指套式探头，包括指套本体11、安装于指套本体11上的软排线13、安装于指套本体11且与软排线13一端电性连接的发光管15、安装于指套本体11且与软排线13另一端电性连接的接收管17、及一端与软排线电性连接的导线19；所述导线19的另一端与外部设备电性连接，从而将该指套式探头与外部设备进行连接，所述指套本体11为下端开口上端封闭而中空的圆筒状一体结构，通过所述指套本体11的下端开口将该指套式探头佩戴于手指上，所述软排线13横跨指套本体11的上端而向所述指套本体11的前后两侧延伸，所述软排线13的两端分别对应手指的指背与指腹而位于所述手指套本体11的前后两侧上，所述发光管15与接收管17位于所述软排线13的两端且分别接触手指的指背与指腹，本领域普通技术人员知道，发光管15也可以位于指腹处而接收管17也可以相应的位于指背处，所述导线19的一端在所述指套本体11的前侧与所述软排线13电性连接，即指套本体11上的与外部设备相连的管路走线主要设置在前侧，相较于现有的将发光管与接收管之间的走线管路设置于硅胶套左右两侧而使其呈扁平状的指套式血氧探头，本发明中指套本体11能够从手指四周方向契合接触手指形状，充分包裹手指四周，手指四周没有明显间隙，使用该指套式探头时，手指伸入指套本体内将其四周均匀撑开从而使得手指四周均被包裹。与现有的指套式血氧探头相比，四周均被包裹增加了接触面积，手指与探头间摩擦阻力增大，不容易脱落，从而可以减少指套对手指的压力，增加了舒适性。圆筒状的设计代替了扁平状结构，对被测手指的相临手指不会产生挤压，增加了舒适性，手指伸入后没有了左右两侧的间隙，手指不能在指套内左右移动，不容易脱落。本领域普通技术人员知道，所述指套本体11为下端开口上端封闭而中空的圆筒状并非要求它的断面(横截面)一定要是典型的圆形，它也可以是椭圆形，类圆形甚至是其他不规则形状，这里强调圆筒状是为了强调使用时它能紧密包裹手指四周，而手指可以描述为圆柱形，因此，这里的圆筒状是与手指的圆柱形相对应的，同时，圆筒状也是为了与现有的指套式血氧探头为扁平状相区别，现有的扁平状血氧探头即使在手指伸入的使用状态也无法包裹手指四周，左右两则会有比较大的间隙。同时，也并非要求本体11在没有使用时必须是圆筒状，因为如果指套本体11很薄时，即使没有使用时它呈其他形状，当手指伸入时，它依旧能紧密包裹手指四周，与手指 外形配合，也可以称为是圆筒状，与现有的扁平状血氧探头区分开来，并达到不同的使用效果。另外，本发明并不要求圆筒状的指套本体11从上往下的所有断面都是相同的形状。本领域普通技术人员知道，该多节指套式探头，根据所述发光管15和接收管17所处理的光信号的波长的情况，可以用于测量血氧饱和度，也可以用于测量其他生理参数；当选择合适波长的发光管15和接收管17时，该多节指套式探头可以用于测量血氧饱和度，当选择其他波长的发光管15接收管17时可以测量其他生理参数。
具体的，所述指套本体11由上往下包括分别对应手指的末端指节和中指节的第一指节套111和第二指节套112；即所述指套本体11的长度大致相对应的为手指的两节指节的长度，从而能够对手指的两节指节进行固定，进一步提高了指套式探头佩戴时的稳固性，而且手指可以自由弯曲，不象现有的指套式血氧探头，手指被指套固定在伸直的位置，容易造成脱落。
具体的，所述指套本体11的后侧在所述第一指节套111和第二指节套112之间设有弯折结构115，所述弯折结构115为间隙、凹槽等具有明显壁厚差别的结构，从而将该指套式探头佩戴于手指上时，第一指节套111和第二指节套112可以在此区域弯曲，进而方便手指弯曲，既可以对于手指的弯曲提供活动空间，增加佩戴时的舒适度，又可以通过第一指节套111在手指弯曲时会被末端指节顶住而不容易脱落，避免指套式探头因被测者不可避免的手指活动而脱落。所述弯折结构115的宽度，长度等尺寸根据实际效果来确定。
具体的，所述指套本体11的前后两侧分别设有一安装槽116，所述发光管15与接收管17固定于所述安装槽116内，具体的，所述发光管15与接收管17分别通过透明封胶固定于所述安装槽116内；所述指套本体11上还设有一走线槽117，该走线槽117自指套本体11的上端向两侧延伸至每一安装槽116，所述软排线13固定于所述走线槽117内，具体的，所述软排线13通过透明或不透明封胶固定于所述走线槽115内，同时也起到对所述软排线13进行防水保护的作用。
具体的，所述走线槽117可以位于指套本体11的内侧，也可以位于指套本体11的外侧，相应地，软排线13可以在所述指套本体11的内侧走线，也可以在所述指套本体11的外侧走线。
具体的，所述安装槽116的开口可以位于所述指套本体11的内侧，也可以位于所述指套本体11的外侧，当所述安装槽116的开口位于所述指套本体11的 外侧时，在所述安装槽116的槽底即所述指套本体11的内侧还应该设有一个透明窗口以使得红光与红外线光可以穿过，实现发光管15与接收管17对光线的发射与接收。
具体的，所述指套本体11的前侧面内还设有导线槽118，所述导线槽118用于安装与所述软排线13一端电性连接的导线19，从而使得该指套式探头通过导线19与外部设备电性连接。
具体的，本领域普通技术人员所知道的，导线槽118可以走行在整个第二指节套112上，也可以只在第二指节套112上走行一段长度，或者只走行在第一指节套111上，相应的，所述导线槽118可以自第二指套112的下端向上延伸至第一指节111套前侧的安装槽，也可以自第二指套112的中部向上延伸至第一指节111套前侧的安装槽，或者自第一指节套111向上延伸至第一指节套111前侧的安装槽116。如果导线槽118只走行在第一指节111上，则第二指节套112上各个侧面可以具有相同的壁厚。如果导线槽118部分走行在第二指节套112上，则第二指节套112的不具有导线槽118的各侧面可以具有相同的壁厚。
具体的，指套本体11的圆筒状结构中，除导线槽118所在的前侧面比较厚外，第二指节套112的其他三个侧面的壁厚均匀，如果导线槽118不设置在第二指节套112处，则第二指节套112的各个侧面的壁厚均匀，而现有的指套式血氧探头由于存在局部厚度加强及有发光管接收管软排线等走线，因此无法做到四个侧面的壁厚均匀一致。这样，当手指伸入指套本体11时，第二指节套112处具有三个或四个侧面能够均匀扩张，密切包裹手指，与现有的指套式血氧探头只有上下两个面部分接触点包裹手指相比，舒适性更好，更不易脱落。本领域普通技术人员知道，壁厚均匀有利于指节套在手指伸入时均匀扩张，增加舒适感。这里的壁厚均匀指的是任意指定80％的待考察区域面积内(例如考察某个侧面时，则任意取该侧面上80％的区域面积进行考察)最厚处与最薄处的壁厚相差不超过最厚处的50％，如果只是局部有细小的装饰点凸起，并不明显影响手指伸入时均匀扩张，可以认为该凸起点所在部位仍是壁厚均匀的。
具体的，所述指套本体11具有用于安装发光管15、接收管17、软排线13、及导线19的安装区域、及与所述安装区域相连接的非安装区域，第二指节套112的非安装区域的平均壁厚较第一指节套111的非安装区域的平均壁厚可以变薄。本领域所公知的，硅胶指套越薄则扩张性越好，可以适用更多粗细不同的 手指，对手指产生的压力会小，舒适性更好。但第一指节套111由于固定有发光管15与接收管17等，因此，第一指节套111前后两个侧面无法做得很薄，而第二指节套112上没有这些附着物，因此可以做得比第一指节套111更薄，这样，第二指节套112可以起到固定指套于手指上的作用，而第一指节套111可以只起到测量的作用。现有的指套式血氧探头由于只有一节，而且需要保证有足够的夹持力，无法把壁厚做得很薄，不算发光管接收管及走线处的壁厚，其他部位平均壁厚至少也在1mm以上。
具体的，所述指套本体11的第二指节套112上不设有导线槽的侧面的平均壁厚可以是0.01mm-0.1mm。
具体的，所述指套本体11的第二指节套112上不设有导线槽的侧面的平均壁厚也可以是0.1mm-0.5mm。
具体的，所述指套本体11的第二指节套112上不设有导线槽的侧面的平均壁厚也可以是0.5mm-1.0mm。
具体的，所述指套本体11的第二指节套112的内径可以减小。这里所说的内径指的是衡量第一指节套111及第二指节套112容纳手指的内腔的大小的指标，由于两个指节套并非是典型的圆柱形，因此所说的内径并非是某个特定横截面的直径，如果需要用某种测量方式来测量的话，可以采用一个直径可以变化的圆柱形模拟手指分别伸入到第一指节套111及第二指节套112中，由小到大逐渐增加圆柱形模拟手指的直径，当刚好撑开第一指节套111、第二指节套112，第一指节套111、第二指节套112刚好四周紧密包裹接触圆柱形模拟手指而又不对模拟手指产生明显压力时，也即此时第一指节套111、第二指节套112只是被模拟手指撑开成圆柱形而没有明显拉伸，测量此时模拟手指的直径即可以认为是所说的第一指节套111的内径、第二指节套112的内径。同时，由于第一指节套111的内腔并非是上下相等，因此，这里所说的用模拟手指测量的部位是指第一指节套111的发光管15与接收管17所在的圆周部位到弯折结构115之间的部分，第一指节套111的前端部分往往缩小以适应手指形状且对手指固定作用不大，因此不作为衡量第一指节套111大小的指标。本领域普通技术人员知道，硅胶指套内径越小则对手指包裹得越紧，指套越不容易脱落，但对手指的压力也变大。通常手指的第一指节比第二指节要细，为V字形，因此，现有的指套在设计时，第一指节的内腔间隙比第二指节的内腔间隙要小，也就是，从内部 看，现有指套的内腔间隙是越往指尖越小，这样手指受力比较均匀，但由于每个人的手指均不一样，因此，理论上可以做到整个手指受力均匀，但实际上由于第一指节及第二指节相对尺寸很难成比例，因此，现有的指套有可能手指前端受力大而第二指节部分受力小，既容易脱落又影响测量。而本发明中，当所述指套本体11的第二指节套112厚度变薄后对手指压力减小时，可以相对缩小第二指节套112的内径，也就是说，第二指节套112可以做得与第一指套111一样的内径甚至更小，容纳手指的内腔纵剖面由前往后看可以呈U字形而不是通常的V字形。
具体的，所述软排线13的两端分别位于所述第一指节套111的前后两侧上，所述发光管15与接收管17位于所述软排线13的两端且分别接触手指的指甲与指腹。由于手指的两侧面没有软排线，从而解决了现有的指套式血氧探头佩戴时相对较硬的隆起会压迫相临两侧手指导致舒适性差的问题。
具体的，所述第一指节套111的左右两侧上设有第一窗口113，进一步的，所述第二指节套112的左右两侧上设有第二窗口114，该第一窗口113和第二窗口114增加了指套本体11的弹性，避免手指过紧的固定于指套本体11内，另外，该窗口增加了指套的透气性，解决了现有的指套式血氧探头长期使用时由于透气性差而容易产生汗水的问题，提高了指套的佩戴舒适度。
具体的，所述指套本体11的材料为弹性材料，如硅胶、橡胶等。
综上所述，本发明提供的一种多节指套式探头，包括指套本体、安装于指套本体上的软排线、发光管、接收管、及与软排线电性连接的导线；所述指套本体为下端开口的圆筒状，所述软排线横跨指套本体的上端，其两端分别对应手指的指背与指腹而位于所述手指套本体的前后两侧上，所述发光管与接收管分别接触手指的指背与指腹，所述导线的一端在所述指套本体的前侧与所述软排线电性连接，即指套本体上的与外部设备相连的管路走线主要设置在前侧，相较于现有的将发光管与接收管之间的走线管路设置于硅胶套左右两侧而使其呈扁平状的指套式探头，本发明中指套本体契合手指形状，充分包裹手指四周，使用时，手指伸入指套本体内时需将其四周均撑开从而使得手指四周均被包裹，阻力大，佩戴时稳固、不易脱落，适合长时间使用，适用于睡眠呼吸监测，且所述指套本体由上往下包括分别对应手指的末端指节和中指节的第一指节套和第二指节套，从而能够对手指的两节指节进行固定，进一步提高了指套 式探头佩戴时的稳固性。
以上所述，对于本领域的普通技术人员来说，可以根据本发明的技术方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形都应属于本发明权利要求的保护范围。
