Description

集成有血氧传感器的手持式多参数测量仪
【技术领域】
本发明涉及医疗器械技术领域，特别是涉及一种集成有血氧传感器的手持式多参数测量仪。
【背景技术】
多参数测量装置通常包含多个传感器，从而实现一系列生理参数的测量，如心电、体温、血糖、血压、血氧饱和度、脉率、血流灌注强度等。其中，通过血氧传感器可以测量血氧饱和度、脉率、血流灌注强度；通过心电传感器（心电导联），可以测量心电图、心率等重要信息。
由于多参数测量装置的使用者为非专业的家庭用户，使用方式多为自测，且通常至少集成两个传感器，为了保证产品的易用性与易维护性，多个传感器集成方式与合理布局显得格外重要。但是现有的多参数测量装置集成血氧传感器的方式不尽合理，存在使用不便的问题。或者虽然方便使用，但是存在测量精度差的问题。
例如，现有多参数测量装置集成血氧传感器时，
（1）通过电缆线及连接器直接在多参数测量装置的外壳上连接一个血氧传感器探头。而电缆线容易缠绕，存在使用不便的问题。此外，包含血氧传感器探头、电缆、连接器三大部件，成本较高，而且电缆易故障，清洁及维护都不方便。
（2）直接在多参数测量装置的表面集成反射式血氧传感器，也即血氧传感器的红外/红光发光器件与光电接收器件裸露于多参数测量装置同一表面上，仅有透明胶覆盖。测量时，将测量部位紧贴在血氧传感器表面，通过测量组织反射回来的红光/红外光强度，来测量血氧饱和度。采用反射式原理测量血氧，存在原理上的局限性，相比透射式血氧测量方式，其测量精度和测量重复性更低，尤其更容易受环境光的干扰，为了获得稳定的测量结果，需要对环境光采取遮蔽措施。采用上述现有结构方式测量血氧饱和度时，测量部位无遮光装置，易受周围环境光的干扰，从而影响测量精度或导致测量失败。例如，日光灯等环境光直接照射在手指背面，形成很大的干扰。此外，由于红外/红光发光器件与光电接收器件直接暴露在外表面，导致红外/红光发光器件与光电接收器件表面容易受到污染和磨损，从而影响透光率，并对测量造成影响。
【发明内容】
基于此，有必要提供一种适合家庭自测用且具有较高测量精度的集成有血氧传感器的手持式多参数测量仪。

在其中一个实施例中，所述盖板与所述壳体贴合有所述盖板的侧壁之间形成有缓冲腔，所述壳体贴合有所述盖板的侧壁内陷形成所述缓冲腔。
在其中一个实施例中，所述盖板贴合于所述壳体拐角处的侧壁上，且所述盖板与所述壳体贴合有所述盖板的侧壁之间形成有缓冲腔；所述盖板为弧形板，所述壳体贴合有所述盖板的侧壁呈圆弧状，所述盖板与所述壳体贴合有所述盖板的侧壁配合形成所述缓冲腔。
在其中一个实施例中，所述盖板的内表面的弯曲方向与所述壳体贴合有所述盖板的侧壁的弯曲方向相同，且与所述盖板内表面对应的圆心位于所述壳体内；
所述盖板的外表面的弯曲弧度与所述壳体贴合有所述盖板的侧壁的弯曲弧度相同，且所述盖板的外表面的弯曲方向与所述壳体贴合有所述盖板的侧壁的弯曲方向相同，与所述盖板外表面对应的圆心位于所述壳体内。
在其中一个实施例中，还包括设于所述壳体上的限位结构，所述限位结构用于限制所述盖板相对于所述壳体转动的最大转动角度，其中，所述最大转动角度的范围为15度~75度。
在其中一个实施例中，所述限位结构为设于所述壳体贴合有所述盖板的侧壁上的挡板结构，且所述限位结构位于所述盖板与所述壳体连接的一端，以便所述盖板转动到特定角度时，所述盖板与所述壳体连接的一端被所述限位结构阻挡，从而限制所述盖板进一步转动。
在其中一个实施例中，还包括用于使所述盖板与所述壳体的侧壁贴合的复位装置。
在其中一个实施例中，所述复位装置为磁吸机构；
所述复位装置包括两磁铁块，两所述磁铁块分别设于所述盖板与所述壳体贴合的一侧上及所述壳体贴合有所述盖板的侧壁上，且相互吸合；
或者所述复位装置包括一磁铁块及一铁片，所述磁铁块设于所述盖板与所述壳体贴合的一侧上或所述壳体贴合有所述盖板的侧壁上，且与所述铁片相互吸合。

使用上述手持式多参数测量装置测量血氧饱和度时，使用者的一只手握持住其壳体的第一表面与第二表面，且握持测量装置的手的其中一个手指插入盖板与壳体之间。从而使得信号处理单元控制光发射单元交替发射的红光与红外光透过手指或经手指反射后，传输至光接收单元上。进而信号处理单元根据光接收单元接收的信号计算出血氧饱和度。
上述手持式多参数测量装置通过在其壳体的侧壁上设置盖板，进而将血氧传感器集成于其壳体上。无需使用电缆线及连接器，具有使用方便、容易维护、成本低、测量精度高、抗环境光干扰好等特点。当光发射单元与光接收单元同侧设置时，盖板能有效防止环境光的干扰，从而提高反射式血氧测量的精度与重复性。盖板也能较好的保护光发射单元与光接收单元，能有效避免因光发射单元与光接收单元受到污染及磨损而影响透光率的问题，进一步提供反射式血氧测量的精度与重复性。当光发射单元与光接收单元相对侧设置时，相对于反射式血氧测量，上述手持式多参数测量装置能实现更高精度的透射式血氧测量。上述手持式多参数测量装置易用、易维护，非常适合非专业人员在家中自测使用。此外，盖板设于壳体的侧壁上，从而使得上述手持式多参数测量装置具有更多空间去合理集成其他传感器。

【具体实施方式】
为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的较佳实施例。但是，本发明可以以多种不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本发明的公开内容的理解更加透彻全面。
需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。本文所使用的术语“及／或”包括一个或多个相关的所列项目的任意的和所有的组合。
如图1-4所示，一实施方式的集成有血氧传感器的手持式多参数测量仪10，包括壳体100、盖板200、血氧测量装置300、限位结构400及复位装置500。
壳体100具有侧壁110以及相对的第一表面120与第二表面130，且侧壁110、第一表面120及第二表面130围合形成一容置腔140。盖板200贴合于壳体100的侧壁110上，且与壳体100可转动连接，以便手指容置于盖板200与壳体100贴合有盖板200的侧壁之间。在本实施方式中，盖板200通过转轴210与壳体100可转动连接。
如图1及图5所示，在本实施方式中，壳体100呈长方体形。当使用者的右手20握持住壳体100的第一表面120与第二表面130时，壳体100的第一表面120正对使用者，盖板200位于壳体100的右上方，且盖板200贴合于壳体100拐角处的侧壁上。壳体100贴合有盖板200的侧壁呈圆弧状。测量血氧时，由被测量手指22之外的其他手指握持多参数测量装置10，被测量手指22只需插入盖板200与壳体100贴合有盖板200的侧壁之间即可。
如图6及图7所示，可以理解，在其他实施方式中，盖板200也可以贴合于壳体100上方的侧壁上，壳体100贴合有盖板200的侧壁呈平面状。可以理解，壳体100也可以呈圆柱体形等其他形状。当壳体100呈圆柱体形时，两个圆形表面即为第一表面及第二表面。
进一步，盖板200与壳体100贴合有盖板200的侧壁之间形成有缓冲腔。当外力压迫或撞击盖板200时，缓冲腔能有效保护光发射单元312及光接收单元314。可以理解，在其他实施方式中，盖板200与壳体100贴合有盖板200的侧壁之间可以没有缓冲腔。
在本实施方式中，盖板200为弧形板，壳体100贴合有盖板200的侧壁呈圆弧状，盖板200与壳体100贴合有盖板200的侧壁配合形成缓冲腔。壳体100贴合有盖板200的侧壁呈圆弧状，从而便于被测量手指22的指尖与壳体100贴合，进而使得使用者处于一个较舒适的状态下测量血氧饱和度。此外，当盖板200贴合于壳体100拐角处的侧壁上，且壳体100贴合有盖板200的侧壁呈圆弧状时，能在确保手持式多参数测量仪10具有小尺寸的前提下，获得最大可能的手指测量部位容纳空间，在保证精确测量的前提下维持设备的小体积。并且弧形的表面能与手指形成良好的接触与遮蔽，进一步减小环境光的干扰。
进一步，在本实施方式中，盖板200的内表面的弯曲方向与壳体100贴合有盖板200的侧壁的弯曲方向相同，且与盖板200内表面对应的圆心位于壳体100内。
进一步，在本实施方式中，盖板200的外表面的弯曲弧度与壳体100贴合有盖板200的侧壁的弯曲弧度相同，且盖板200的外表面的弯曲方向与壳体100贴合有盖板200的侧壁的弯曲方向相同，与盖板200外表面对应的圆心位于壳体100内。从而使得上述手持式多参数测量仪10具有较好的外观，且能对血氧传感器310形成封闭的防护。
可以理解，在其他实施方式中，盖板200与壳体100贴合有盖板200的侧壁之间形成有缓冲腔，壳体100贴合有盖板200的侧壁内陷形成缓冲腔。
在本实施方式中，为了使上述手持式多参数测量仪10具有较好的外观，使得壳体100的其三个拐角处的侧壁也呈圆弧状。壳体100的四个拐角处均呈圆弧状，从而不易出现壳体100碰伤使用者的情况。
如图5所示，在本实施方式中，在使用手持式多参数测量装置10测量血氧饱和度时，使用者一只手20握持住壳体100的第一表面120及第二表面130，被测量手指22插入盖板200与壳体100贴合有盖板200的侧壁之间。在本实施方式中，被测量手指22为食指，可以理解，被测量手指22也可以为中指。
血氧测量装置300包括血氧传感器310、信号处理单元320、光电接口单元330、存储单元340及显示单元350。
血氧传感器310包括光发射单元312及光接收单元314。光发射单元312用于交替发射红光与红外光。光接收单元314用于接收光发射单元312发射的红光与红外光。在本实施方式中，光发射单元312设于盖板200与壳体100贴合的一侧上，光接收单元314设于壳体100贴合有盖板200的侧壁上。可以理解，在其他实施方式中，光接收单元314可以设于盖板200与壳体100贴合的一侧上，而光发射单元312设于壳体100贴合有盖板200的侧壁上。也可以将光发射单元312及光接收单元314均设于壳体100贴合有盖板200的侧壁上。
当光发射单元312与光接收单元314同侧设置时，血氧传感器310的测量原理为反射式。盖板200能有效防止环境光的干扰，从而提高反射式血氧测量的精度与重复性。盖板200也能较好的保护光发射单元312与光接收单元314，能有效避免因光发射单元312与光接收单元314受到污染及磨损而影响透光率的问题，进一步提供反射式血氧测量的精度与重复性。
当光发射单元312与光接收单元314相对设置时，血氧传感器310的测量原理为透射式。透射式测量方式相对于反射式测量方式具有更高的测量精度。
信号处理单元320容置于壳体100的容置腔140中，用于控制光发射单元312交替发射红光与红外光，并根据光接收单元314接收的信号计算出血氧饱和度。在本实施方式中，信号处理单元320根据光接收单元314接收的信号还可以计算出脉率、血流灌注强度及脉搏波形中的至少一种。
在本实施方式中，光发射单元312与光接收单元314通过光电接口单元330与信号处理单元320电气连接。为了保护光发射单元312与光接收单元314，光发射单元312与光接收单元314的表面均由透明胶密封。
存储单元340容置于壳体100的容置腔140内，且与信号处理单元320电气连接，用于存储信号处理单元320计算出的血氧饱和度。当然也可以存储脉率、血流灌注强度等。
显示单元350设于壳体100上，且与信号处理单元320电气连接，用于显示信号处理单元320计算出的血氧饱和度。在本实施方式中，显示单元350设于壳体100的第一表面120上。显示单元350还可以显示脉率、血流灌注强度与脉搏波形中的至少一种。
在本实施方式中，手持式多参数测量装置10还集成有心电传感器、血糖传感器和体温传感器中的至少一种。如图7所示，以集成心电传感器为例，心电传感器的第一心电极（呈圆形）可以设于图1中的30处，心电传感器的第二心电极（呈条状）可以设于与第一心电极相对的侧壁110上，心电传感器的心电测量电路容置于壳体100的容置腔140内。第一心电极、心电测量电路、第二心电极与使用者构成回路即可实现心电测量。同时测量血氧和心电时，食指22插入盖板200与壳体100之间，拇指24按压住第一心电极，第二心电极与使用者的另外一只手40的手掌或者胸部或者脚踝部位的皮肤接触。
在本实施方式中，限位结构400设于壳体100上用于限制盖板200相对于壳体100转动的最大转动角度。进一步，在本实施方式中，限位结构400为设于壳体100贴合有盖板200的侧壁上的挡板结构，且位于盖板200与壳体100连接的一端，以便盖板200转动到特定角度时，盖板200与壳体100连接的一端被限位结构400阻挡住，从而限制其进一步的转动。
在本实施方式中，最大转动角度的取值范围为15度~75度。最大转动角度太小，被测量手指22会无法插入到盖板200与壳体100之间的最佳测量区域；或者出现盖板200对被测量手指22形成较大的压迫力的情况，进而影响测量。最大转动角度太大，盖板200会出现脱离被测手指22的情况，导致光发射单元312与光接收单元314在测量时产生较大角度差从而无法对正，导致无法测量。进一步，最大转动角度优选为45度。
进一步，在本实施方式中，复位装置500用于使盖板200与壳体100贴合。在被测量手指22插入盖板200与壳体100之间进行测量时，复位装置500会产生一定的回复力从而使得盖板200以一定压力压贴在被测量手指22上，从而减小被测量手指22与光发射单元312及光接收单元314之间的空隙，提高测量稳定性与精度。在被测量手指22取出不测量时，通过复位装置500的作用，盖板200能自动以一定的吸合力贴合在侧壁上，从而形成对光发射单元312及光接收单元314的保护，且盖板200也不容易受到意外外力作用而翻折损坏，外观上也更美观。
在本实施方式中，复位装置500为磁吸机构。复位装置500包括两磁铁块510，两磁铁块510分别设于盖板200与壳体100贴合的一侧上及壳体100贴合有盖板200的侧壁上。两磁铁块510位于盖板200与壳体100连接的一端，且相互吸合。可以理解，在其他实施方式中，复位装置500也可以包括一磁铁块及一铁片，磁铁块设于盖板200与壳体100贴合的一侧上，铁片设于壳体100贴合有盖板200的侧壁上。磁铁块与铁片位于盖板200与壳体100连接的一端，且相互吸合。显然，也可以将铁片设于盖板200与壳体100贴合的一侧上，而将磁铁块设于壳体100贴合有盖板200的侧壁上。
可以理解，在其他实施方式中，复位装置500也可以为设于转轴210上的弹簧机构。
进一步，在本实施方式中，为方便手指插入顶开与壳体100贴合的盖板200。盖板200远离与壳体100连接的一端的端面与壳体100之间存在手指插入槽220。
如图5所示，使用上述手持式多参数测量装置10测量血氧饱和度时，使用者的一只手20握持住其壳体100的第一表面120与第二表面130，且握持测量装置的手的其中一个手指22插入盖板200与壳体100之间。从而使得信号处理单元320控制光发射单元312交替发射的红光与红外光透过手指22或经手指22反射后，传输至光接收单元314上。进而信号处理单元320根据光接收单元接收314的信号计算出血氧饱和度。
上述手持式多参数测量装置10通过在其壳体100的侧壁110上设置盖板200，进而将透射式血氧传感器310集成于其壳体100上。无需使用电缆线及连接器，具有使用方便、容易维护、成本低、测量精度高、抗环境光干扰好等特点。
当光发射单元312与光接收单元314同侧设置时，盖板200能有效防止环境光的干扰，从而提高反射式血氧测量的精度与重复性。盖板200也能较好的保护光发射单元312与光接收单元314，能有效避免因光发射单元312与光接收单元314受到污染及磨损而影响透光率的问题，进一步提供反射式血氧测量的精度与重复性。
当光发射单元312与光接收单元314相对侧设置时，相对于反射式血氧测量，上述手持式多参数测量装置10能实现更高精度的透射式血氧测量。上述手持式多参数测量装置10易用、易维护，非常适合非专业人员在家中自测使用。此外，盖板200设于壳体100的侧壁110上，从而使得上述手持式多参数测量装置10具有更多空间去合理集成其他传感器。
此外，上述手持式多参数测量装置10在测量血氧的过程中，被使用者握持在手20上，盖板200轻轻压住手指22即可测量血氧，且不会出现血氧传感装置脱落或移位的情况。相对于传统的佩戴式血氧计，被测量手指22无需承受设备的重量，也不存在需要较大的夹持力来维持设备不脱落的情况（较大的夹持力会影响手指局部血流的畅通性从而影响测量），从而上述手持式多参数测量装置10能有效改善测量的舒适性以及提高测量的精度。使用者在测量血氧的过程中，可以随意走动，使用方便。而且，在使用上述手持式多参数测量装置10测量血氧时，使用者的另一手处于空闲状态，方便使用者同时进行其他生理参数的检测。相对于只具有测量血氧功能的血氧计而言，上述手持式多参数测量装置10的功能多样。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
