Description

输液设备 技术领域
本发明是关于一种输液设备。
背景技术
在迈向老年化及长寿的社会，医疗器材的需求日以激增，因此，医疗器材的品质也变得备受关注，医疗器材的可靠性及安全性无疑为业界一个重要的课题。
一般而言，以输液设备向病患输送医疗流体，是医疗过程中常用的做法。然而，在输液帮浦的操作过程中，每一步骤都必须非常小心处理，以避免非预期的流体流入病患的身体中。
发明内容
本发明的目的之一在于提供一种输液设备，其能把输液管安装至卡扣装置或把输液管从卡扣装置脱离的过程变得更为稳定。
根据本发明的一实施方式，一种输液设备包含夹具主体、管座以及卡扣装置。夹具主体沿第一方向具有相对的第一端以及第二端，夹具主体具有第一穿孔，第一穿孔沿第一方向延伸，并包含相连通的一第一子穿孔以及一第二子穿孔，第一子穿孔与第二子穿孔沿第一方向排列，第一子穿孔沿一第二方向的一第一宽度大于第二子穿孔沿该第二方向的一第二宽度。夹具主体设置有一对第一凸块，沿第二方向位于第二端的相对两侧，第二方向与第一方向彼此垂直。管座具有第二穿孔以及第三穿孔，夹具主体穿越第二穿孔并可相对管座沿第一方向滑动，当管座相对夹具主体滑动时，第三穿孔可于对应第一子穿孔的位置与对应第二子穿孔的位置之间切换，管座更具有一对凹槽，沿第二方向位于管座的相对两侧。卡扣装置包含机体以及一对卡勾结构。机体具有安装孔，安装孔配置以让夹具主体与管座沿第一方向插入。卡勾结构设置于机体，且位于安装孔沿第二方向的相对两侧，卡勾结构均包含勾部以 及第二凸块，勾部配置以卡合于凹槽内，第二凸块之间的最短距离少于第一凸块之间的最长距离。
在本发明一或多个实施方式中，上述的第一子穿孔比第二子穿孔接近第一端。
在本发明一或多个实施方式中，上述的第三穿孔沿第二方向的第三宽度大于第二宽度。
在本发明一或多个实施方式中，上述的第一宽度相同于第三宽度。
在本发明一或多个实施方式中，上述的第一子穿孔的第一宽度朝向第二子穿孔渐缩。
在本发明一或多个实施方式中，上述的第一凸块彼此对称。
在本发明一或多个实施方式中，上述的卡勾结构还各具有枢接部。此枢接部枢接于机体，第二凸块位于对应的枢接部与对应的勾部之间。
在本发明一或多个实施方式中，上述的卡扣装置还包含一对弹性元件，弹性元件分别弹性连接对应的卡勾结构与机体。
在本发明一或多个实施方式中，上述的第二凸块各具有弧面，弧面彼此相对。
在本发明一或多个实施方式中，上述的第一凸块分别呈梯形。
本发明上述实施方式至少具有以下优点：
(1)由于夹具主体与第一凸块为对称结构，因此，当使用者把夹具主体连同第一凸块插入卡扣装置或从卡扣装置把夹具主体连同第一凸块拉出时，第二凸块因顶向第一凸块而施加于夹具主体的力量亦为对称的。如此一来，把输液管安装至卡扣装置或把输液管从卡扣装置脱离的过程也变得更为稳定，也能减低夹具主体、第一凸块以及卡勾结构因受力不均而损坏的风险。
(2)由于把输液管从卡扣装置抽离之前，输液管已被压扁于夹具主体的第二子穿孔内，得以防止医疗流体于输液管中流通，更因上述操作系采用机械操作的方式进行，其操作的可靠性及安全性得以有效保障。

以下将以附图揭示本发明的多个实施方式，为明确说明起见，许多实务上的细节将在以下叙述中一并说明。然而，应了解到，这些实务上的细节不应用以限制本发明。也就是说，在本发明部分实施方式中，这些实务上的细节是非必要的。此外，为简化附图起见，一些已知惯用的结构与元件在附图中将以简单示意的方式绘示。且若实施上为可能，不同实施例的特征可以交互应用。
请参照图1，其为绘示依照本发明一实施方式的夹具主体110与管座130的立体组立图。在本实施方式中，如图1所示，夹具主体110与管座130适于让输液管200穿越，并且管座130可连同输液管200沿第一方向D1相对夹具主体110滑动。
请参照图2，其为绘示图1的夹具主体110与管座130插入卡扣装置140的局部剖面图，其中第一凸块120顶向第二凸块147。在本实施方式中，如图1～2所示，输液设备100包含夹具主体110、管座130以及卡扣装置140。夹具主体110沿第一方向D1具有相对的第一端111以及第二端112，而夹具 主体110具有第一穿孔H1，第一穿孔H1沿第一方向D1延伸，且适于让输液管200穿越。夹具主体110设置有第一凸块120，第一凸块120沿第二方向D2位于第二端112的相对两侧，第二方向D2与第一方向D1实质上彼此垂直。管座130具有第二穿孔H2，夹具主体110穿越第二穿孔H2并可如上所述相对管座130沿第一方向D1滑动。换句话说，管座130可连同输液管200沿第一方向D1相对夹具主体110滑动，而输液管200则可于第一穿孔H1内沿第一方向D1相对夹具主体110滑动。管座130更具有一对凹槽G，凹槽G沿第二方向D2位于管座130的相对两侧。在本实施方式中，管座130的凹槽G更可连通第二穿孔H2，但本发明并不以此为限。
再者，卡扣装置140包含机体141以及一对卡勾结构145。机体141具有安装孔H，安装孔H配置以让夹具主体110与管座130沿第一方向D1插入机体141。卡勾结构145设置于机体141，且位于安装孔H沿第二方向D1的相对两侧，亦即安装孔H位于卡勾结构145之间。卡勾结构145均包含勾部146以及第二凸块147，勾部146配置以卡合于凹槽G内，而第二凸块147之间的最短距离DS少于第一凸块120之间的最长距离DL。
具体而言，如图2所示，卡勾结构145还包含枢接部148。枢接部148枢接于机体141，第二凸块147位于对应的枢接部148与对应的勾部146之间。如上所述，第二凸块147之间的最短距离DS少于第一凸块120之间的最长距离DL，因此，当夹具主体110与管座130沿第一方向D1插入机体141的安装孔H时，第一凸块120顶向卡勾结构145的第二凸块147，并使卡勾结构145绕枢接部148相对机体141旋转，从而使第一凸块120通过第二凸块147而插入机体141中。
进一步而言，如图2所示，第一凸块120呈梯形，因此，当第一凸块120顶向卡勾结构145的第二凸块147时，第一凸块120因梯形所形成的斜面，有助于第一凸块120通过第二凸块147。而且，卡勾结构145的第二凸块147具有弧面149，弧面149彼此相对，因此，当卡勾结构145绕枢接部148相对机体141旋转时，第二凸块147的弧面149可以顺畅地与第一凸块120因梯形所形成的斜面彼此滑行。
另外，在本实施方式中，如图2所示，卡扣装置140还包含一对弹性元件143，弹性元件143分别弹性连接对应的卡勾结构145与机体141。因此，当卡勾结构145绕枢接部148相对机体141旋转，从而使第一凸块120通过第二凸块147而插入机体141中之后，弹性元件143可使卡勾结构145复位。在实务的应用中，弹性元件143可为弹簧或扭簧等，但本发明并不以此为限。
从结构上而言，第一穿孔H1包含相连通的第一子穿孔H11以及第二子穿孔H12，第一子穿孔H11与第子二穿孔H12沿第一方向D1排列，第一子穿孔H11比第二子穿孔H12接近第一端111，第一子穿孔H11沿第二方向D2的第一宽度W1大于第二子穿孔H12沿第二方向D2的第二宽度W2。
再者，如图2所示，管座130具有第三穿孔H3，第三穿孔H3适于让输液管200穿越，而管座130的第三穿孔H3沿第二方向D2的第三宽度W3大于第二子穿孔H12的第二宽度W2。在实务的应用中，第一子穿孔H11的第一宽度W1可相同于第三穿孔H3的第三宽度W3，但本发明并不以此为限。
当使用者把输液管200穿越管座130以及夹具主体110时，输液管200穿越管座130的第三穿孔H3以及夹具主体110的第一子穿孔H11。当管座130相对夹具主体110滑动时，第三穿孔H3可于对应第一子穿孔H11的位置与对应第二子穿孔H12的位置之间切换，亦即输液管200可随着第三穿孔H3于第一子穿孔H11与第二子穿孔H12之间切换。再者，如图2所示，第一子穿孔H11的第一宽度W1朝向第二子穿孔H12渐缩，有助于提高输液管200于第一子穿孔H11与第二子穿孔H12之间切换时的顺畅度。
请参照图3，其为绘示图1的夹具主体110与管座130插入卡扣装置140的局部剖面图，其中卡勾结构145的勾部146卡合于管座130的凹槽G内。如图3所示，当第一凸块120通过卡勾结构145的第二凸块147后，夹具主体110与管座130连同输液管200继续插入至机体141的安装孔H内。相似地，当管座130顶向勾部146时，卡勾结构145受到管座130的推动而绕枢接部148相对机体141旋转，以使卡勾结构145的勾部146可以越过管座130的边缘而卡合于管座130的凹槽G内。如此一来，管座130相对卡扣装置140的机体141得以固定，亦即输液管200亦相对卡扣装置140的机体141得以 固定，而穿越管座130的输液管200维持在夹具主体110的第一子穿孔H11内。此时，输液管200适于让医疗流体(图未示)流通于其中。
在实务的应用中，夹具主体110的第一端111为夹持部，以让使用者可以用手指夹持，并把夹具主体110插入机体141的安装孔H。具体而言，作为夹持部的第一端111，其沿第二方向D2的尺寸大于第二穿孔H2的尺寸，因此，管座130无法通过夹具主体110的第一端111而与夹具主体110分离。相对地，当使用者以手指夹持作为夹持部的第一端111，并把夹具主体110插入机体141的安装孔H时，管座130也会被作为夹持部的第一端111推动而向安装孔H内移动，以使管座130可顶向卡勾结构145的勾部146。
请参照图4，其为绘示图1的夹具主体110与管座130从卡扣装置140拉出的局部剖面图，其中管座130的第三穿孔H3对应夹具主体110的第二子穿孔H12。如图4所示，由于卡勾结构145的勾部146卡合于管座130的凹槽G内而使管座130相对卡扣装置140的机体141固定，因此，当使用者以手指夹持作为夹持部的第一端111而把夹具主体110从卡扣装置140拉出时，夹具主体110相对管座130滑动，使得管座130的第三穿孔H3移动至对应夹具主体110的第二子穿孔H12，并使得穿越管座130的输液管200从夹具主体110的第一子穿孔H11切换至第二子穿孔H12。
如上所述，第一子穿孔H11的第一宽度W1大于第二子穿孔H12的第二宽度W2，因此，当输液管200从第一子穿孔H11切换至第二子穿孔H12时，输液管200的横切面会被压扁，而输液管200的内壁彼此贴合，使得医疗流体再无法流通于输液管200中。
再者，当输液管200从第一子穿孔H11切换至第二子穿孔H12后，第一凸块120也朝向机体141外顶向卡勾结构145的第二凸块147，使得卡勾结构145绕枢接部148相对机体141旋转，从而使卡合于凹槽G的勾部146从管座130脱离。如此一来，管座130不再受到勾部146的固定而可以连同夹具主体110离开卡扣装置140。
请参照图5，其为绘示图1的具主体110与管座130从卡扣装置140拉出的局部剖面图，其中夹具主体110以及管座130已离开卡扣装置140。如 图5所示，当管座130连同夹具主体110离开卡扣装置140后，输液管200维持在夹具主体110的第二子穿孔H12内，也就是说，当输液管200离开卡扣装置140后，输液管200维持在第二子穿孔H12内并处于被压扁的状态，因此，医疗流体不会流通于输液管200中。
如图2-5所示，第一凸块120彼此对称。换句话说，夹具主体110与第一凸块120为对称结构。也就是说，当使用者把夹具主体110连同第一凸块120插入卡扣装置140或从卡扣装置140把夹具主体110连同第一凸块120拉出时，第二凸块147因顶向第一凸块120而施加于夹具主体110的力量亦为对称的。如此一来，把夹具主体110连同第一凸块120插入卡扣装置140或从卡扣装置140把夹具主体110连同第一凸块120拉出的过程能变得更为稳定，亦即把输液管200安装至卡扣装置140或把输液管200从卡扣装置140脱离的过程也变得更为稳定。再者，也能减低夹具主体110、第一凸块120以及卡勾结构145因受力不均而损坏的风险。
进一步而言，把输液管200从卡扣装置140抽离之前，输液管200已被压扁于夹具主体110的第二子穿孔H12内，得以防止医疗流体于输液管200中流通，还因上述操作采用机械操作的方式进行，其操作的可靠性及安全性得以有效保障。
综上所述，本发明上述实施方式所揭示的技术方案至少具有以下优点：
(1)由于夹具主体与第一凸块为对称结构，因此，当使用者把夹具主体连同第一凸块插入卡扣装置或从卡扣装置把夹具主体连同第一凸块拉出时，第二凸块因顶向第一凸块而施加于夹具主体的力量亦为对称的。如此一来，把输液管安装至卡扣装置或把输液管从卡扣装置脱离的过程也变得更为稳定，也能减低夹具主体、第一凸块以及卡勾结构因受力不均而损坏的风险。
(2)由于把输液管从卡扣装置抽离之前，输液管已被压扁于夹具主体的第二子穿孔内，得以防止医疗流体于输液管中流通，还因上述操作系采用机械操作的方式进行，其操作的可靠性及安全性得以有效保障。
虽然本发明已以实施方式揭示如上，然其并非用以限定本发明，任何熟悉本技术领域者，在不脱离本发明的精神和范围内，当可作各种的更动与润 饰，因此本发明的之保护范围当由权利要求书界定为准。
