Description

筛检试纸读取系统 技术领域
本发明涉及一筛检试纸读取系统，尤指一种可达到快速筛检以及保护筛检试纸功效之筛检试纸读取系统。
背景技术
随着人类越来越注重自我身体健康状态，筛检，包含生理筛检或环境筛检，就成为了一项非常热门的议题。附图1为一种习用筛检试纸示意图，如图所示：该筛检试纸10上配置有反应区11。当使用者将检体滴于反应区11上后，该反应区11就会与检体起化学反应，而使该反应区11的颜色产生变化。使用者即可根据反应区的颜色变化与对比颜色来分析检体的正常与否。透过人眼辨识颜色变化的精准度非常差，因此进行精密筛检时，大多利用光谱分析仪来进行。
然而，利用光谱分析仪进行筛检时，使用者避居以手动方式将筛检试纸制放于对应的位置供光谱分析仪对反应区进行颜色讯号撷取，此举不但容易造成筛检试纸磨损，更容易导致置放位置不准确而发生无法撷取的窘境，浪费许多时间于筛检试纸位置调校，因此难以堪称实用。
发明内容
本发明的目的之一在于提供一种筛检试纸读取系统，以达到快速筛检以及保护筛检试纸之功效。
为了实现上述发明目的，本发明提供了一种筛检试纸读取系统，包含一筛检试纸，其上配置有若干反应区，系可对若干特定检体产生化学反应，并改变其自身的颜色；一试纸载具，其上配置有一承载槽，用以容置该筛检试纸，且该试纸载具上另配置有若干定位部与一连动部；一输送单元，包括一带动装置与一侦测装置；以及一读取单元；其中，当该侦测装置侦测到该试纸载具上之若干定位部时，则该带动装置就会启动并透过该连动部使该试纸载具移动，使该读取单元撷取该各反应区上之一颜色讯号。
根据本发明的一实施例，该输送单元更包含有一限位装置，用以限制该试纸载具于移动时的位置。
根据本发明的一实施例，该带动装置为一直流马达。
根据本发明的一实施例，该带动装置为一步进马达。
根据本发明的一实施例，该连动部为一齿条。
根据本发明的一实施例，该筛检试纸的特定检体应用为唾液、尿液、血、粪便、水、食品、有毒有害物质或微生物。
根据本发明的一实施例，该侦测装置系为红外线侦测器、光侦测器、雷射光侦测器或影像传感器。
根据本发明的一实施例，该读取单元为光学波长分光装置或光谱分析仪。
根据本发明的一实施例，该限位装置进一步包含一开口为『C』、『ㄇ』或『ㄈ』字形外观，系用以限制该试纸载具于移动时的位置。
附图说明
图1是根据先前技术的一传统的筛查试纸的示意图。
图2是根据本发明的一较佳实施例的一筛检试纸读取系统的示意图。
图3是根据本发明的一较佳实施例的一筛检试纸读取系统的示意图。
具体实施方式
以下描述用于揭露本发明以使本领域技术人员能够实现本发明。以下描述中的优选实施例只作为举例，本领域技术人员可以想到其他显而易见的变型。在以下描述中界定的本发明的基本原理可以应用于其他实施方案、变形方案、改进方案、等同方案以及没有背离本发明的精神和范围的其他技术方案。
本领域技术人员应理解的是，在本发明的揭露中，术语“纵向”、“横向”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”等指示的方位或位置关系是基于附图所示的方位或位置关系，其仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此上述术语不能理解为 对本发明的限制。
可以理解的是，术语“一”应理解为“至少一”或“一个或多个”，即在一个实施例中，一个元件的数量可以为一个，而在另外的实施例中，该元件的数量可以为多个，术语“一”不能理解为对数量的限制。
在说明书及后续的申请专利范围当中使用了某些词汇来指称特定的组件。所属领域中具有通常知识者应可理解，硬件制造商可能会用不同的名词来称呼同一个组件。本说明书及后续的申请专利范围并不以名称的差异来作为区分组件的方式，而是以组件在功能上的差异来作为区分的准则。在通篇说明书及后续的请求项当中所提及的「包含」系为一开放式的用语，故应解释成「包含但不限定于」。
如附图2和3所示，根据本发明的一较佳实施例的一筛检试纸读取系统被阐明，其中该筛检试纸读取系统20，主要由一筛检试纸21、一试纸载具22、一输送单元以及一读取单元26所组成。该筛检试纸21上配置有若干反应区211，系可对若干特定检体(如尿液或血液等等)产生化学反应，并改变其自身的颜色。该试纸载具22上配置有一承载槽221，用以容置该筛检试纸21，并使该筛检试纸21固定于该试纸载具22上。该试纸载具22上另配置有若干定位部222(泛指定位点)与一连动部223(可为一齿条)。该输送单元包括一带动装置25(可为一直流马达或一步进马达)与一侦测装置24，当该侦测装置24侦测到该试纸载具上之若干定位部222时，则该带动装置25就会启动并透过该连动部223使该试纸载具22移动至对应的位置，使该读取单元26撷取该各反应区211上之颜色讯号，上述实施例中的特定检体可应用范围为唾液、尿液、血、粪便、水、食品、有毒有害物质或微生物反应，上述该侦测装置24系可替换为红外线侦测器、光侦测器、雷射光侦测器或影像传感器，上述该读取单元26为光学波长分光装置或光谱分析仪。
此外，为使该试纸载具22于移动时不会与该带动装置25脱离或产生偏移，该输送单元更配置有一限位装置23，其中作动方式使该试纸载具22于移动时，其中该试纸载具22限制于该限位装置23的『ㄈ』字形开口内滑移，以达到上述目的，上述该限位装置23的开口外观可进一步替换为『C』或『ㄇ』等开口。
接续上述实施例，如以检测病患的尿醣数值来说，如果已经确定拿取的筛检试纸为尿醣专用，则可直接进行检测，即将待检尿液与筛检试纸21的反应区211进行接触(通常为滴入或是渗入的方式来进行)，反应区211里面的成分就会与待 检尿液产生化学反应，并改变反应区211的颜色。此外，反应区211内可以包含多种不同的检测区，用以检测尿液中的葡萄糖、蛋白质、酸碱值、潜血值或其他生理数值，达到一次筛检多种数值的功效。待检尿液与筛检试纸21的反应区211进行接触反应后，可将筛检试纸21置入试纸载具22之承载槽221内，并将试纸载具22插入光谱分析仪(即本发明之筛检试纸读取系统20)。
当试纸载具22插入一定深度后，侦测装置24就会侦测到该试纸载具上之若干定位部222，如图2在试纸载具22上的圆点外观，此时本发明之筛检试纸读取系统10就会判定有筛检试纸插入而欲进行筛检作业，其中该带动装置25就会启动，上述该带动装置25系为直流马达或步进马达，并透过为齿条的连动部223带动使该试纸载具22移动至对应的位置，巨观来说类似将试纸载具22吸入的态样。由于是筛检试纸21的规格与带动装置25用以带动试纸载具22移动的距离均为固定或设定好的参数，因此该试纸载具22移动至可供读取单元26撷取各反应区211上之颜色讯号的对应位置会相当准确，系一次就定位。随后，读取单元26就会撷取各反应区211上之颜色讯号，并进行分光处理，达到快速筛检的目的。
再者，由于筛检试纸21置入试纸载具22之承载槽221内，并非直接与光谱分析仪接触，因此受到试纸载具22的保护而不易磨损。
详细说明上述本发明的各项较佳实施例之后，熟悉该项技术人士可清楚的了解，在不脱离下述申请专利范围与精神下可进行各种变化与改变，如限位单元的各种实施态样等等，亦不受限于说明书之实施例的实施方式。
在详细说明上述本发明的各项较佳实施例之后，熟悉该项技术人士可清楚的了解，在不脱离下述申请专利范围与精神下可进行各种变化与改变，如限位单元的各种实施态样等等，亦不受限于说明书之实施例的实施方式。
本领域的技术人员可以理解的是，以上实施例仅为举例，其中不同实施例的特征可以相互组合，以得到根据本发明揭露的内容很容易想到但是在附图中没有明确指出的实施方式。
本领域的技术人员应理解，上述描述及附图中所示的本发明的实施例只作为举例而并不限制本发明。本发明的目的已经完整并有效地实现。本发明的功能及结构原理已在实施例中展示和说明，在没有背离所述原理下，本发明的实施方式可以有任何变形或修改。
