Description

溶配药器 技术领域
本申请实施例涉及但不限于输液配药器械领域，特别是一种用于自动溶配药的溶配药器。
背景技术
现有的输液溶配药基本在使用注射器及其他简易的形式手工配药，在配药的过程中，不能连续配制，效率低，速度慢，劳动强度大；西林瓶包装药品配制时，由于多次穿刺西林瓶及输液容器的胶塞，容易造成漏液及微粒污染；在配制细胞毒性药物、化疗药物、易致敏药物、高活性等药物时，多次穿刺西林瓶及输液容器的胶塞，易产生药物溅出和挥发，对于配药人员造成长期伤害，可能带来不可逆的后果；多次穿刺西林瓶及输液容器的胶塞，由于针头暴露在非无菌环境，微生物会污染针头，污染的微生物可能会随着多次穿刺造成输液微生物二次污染；人工操作易受到操作人员精神状态和配药速度要求的影响，国家要求医疗机构配药中心的建立，需要配药方式的革新，以迄自动化、高效率、无污染的配药方式出现。
发明内容
现有的一次性输液器材和一次性溶配药器，穿刺器暴露在外，人工进行配药时，容易扎伤，且配药速度慢，不适应自动化配制，操作过程中多次穿刺，非全封闭配制，对于较难溶药物，需较长时间的震荡操作进行溶解。冻干粉针剂(西林瓶装)在生产过程中可产生微真空，普通溶药配制过程中，因瓶内有微真空，操作人员很难直接抽出溶解的药液，操作人员需要先重复穿刺将瓶内气压平衡，才能抽出药液。

本发明的实施方式
显然，本领域技术人员基于本申请的宗旨所做的许多修改和变化属于本申请的保护范围。
实施例一：
如图1-图7所示，本实施例提供了一种用于自动溶配药***的一次 性西林瓶溶配药器，其由四根穿刺器28-31、两根弹性输液软管2-3、两个穿刺器基座14-15及一个框架1组成。
其中，如图4所示，穿刺器28-31中空，形成内通道，且穿刺器28-31顶端开孔，并可制成尖锐状，且与内通道连通，底端也开孔与内通道连通。
弹性输液软管2的两端分别与穿刺器29、30的底端相连通，此组成结构可定义为一个通道，该通道的弹性输液软管2可固定在自动溶配药***的一个外接蠕动泵39上，由蠕动泵39提供动力，驱动弹性输液软管2内的流体(如：液体、气体、液固混合体)流动；弹性输液软管3的两端分别与穿刺器28、31的底端相连通，此组成结构可定义为一个通道，该通道的弹性输液软管3可固定在自动溶配药***的一个外接蠕动泵38上，由蠕动泵38提供动力，驱动弹性输液软管3内的流体(如：液体、气体、液固混合体)流动。在图4和图5中，标号24-27为弹性输液软管2、3与穿刺器28-31的连接处。
本溶配药器的两个通道平行，且每端的两个穿刺器28、29以及30、31分别固定在一个穿刺器基座14、15上并呈并联状态。
如图6所示，框架1呈拱桥状，两端为基座导槽井22、23，两个穿刺器基座14、15分别置于框架1两端的基座导槽井22、23内，且可相对于基座导槽井22、23滑动。
溶配药器未使用时，如图1和图4所示，穿刺器基座14、15位于基座导槽井22、23的底部，此时穿刺器28-31均收藏于基座导槽井22、23内；溶配药器使用时，自动溶配药***中的拨针装置(未示出)将穿刺器基座14、15分别沿基座导槽井22、23向外拨动，拨动时穿刺器基座14、15上连接的弹性输液软管2、3可被拖动跟随穿刺器基座14、15运动，穿刺器28-31随之被拨出基座导槽井22、23，使穿刺器28-31的顶端伸出(如图2和图5所示)；此时，如图7所示，一端并联的穿刺器28、29可***输液容器36内，另一端并联的穿刺器30、31可*** 西林瓶37内。这样，在输液容器36和西林瓶37之间形成流体流通的通路。
需要说明的是，两根弹性输液软管2、3的长度均大于两穿刺器基座14、15之间的距离。因此，在未使用时，两根弹性输液软管2、3均处于未张紧状态，如两根弹性输液软管2、3可盘绕起来，以节省空间。
如图6所示，框架1的中下部具有的弧状区域被称之为拱门44，其拱门状设计主要是为了配合自动溶配药***中的两个蠕动泵38、39的滚轮旋转的弧度。拱门44两内侧壁上分别贯穿两条平行孔道40-43，且平行孔道40、41与相邻的基座导槽井23连通，平行孔道42、43与相邻的基座导槽井22连通。两根弹性输液软管2、3的两端分别从拱门44两内侧壁上的孔道40-43穿过并与两侧的基座导槽井22、23内固定在穿刺器基座14、15上的穿刺器28-31连接，弹性输液软管2、3可被固定在孔道40-43内。
进一步，拱门44两内侧壁上的四条平行孔道40-43均处于同一水平高度，且拱门44一内侧壁上的一条孔道42的轴心线与拱门44另一内侧壁上相对应的孔道40的轴心线处于同一直线上，拱门44一内侧壁上另一条孔道42的轴心线与拱门44另一内侧壁上相对应的孔道41的轴心线处于另外的同一直线上，以上所述的两条直线相互平行。这样，位于拱门44内的两根弹性输液软管2、3相互平行。
如图6所示，框架1两侧设有卡扣，一侧的卡扣具有卡扣导面8和卡扣平面10，另一侧的卡扣具有卡扣导面9和卡扣平面11。两个卡扣可与自动溶配药***的卡座(未示出)相连并卡定。当框架1固定在卡座上后，本溶配药器的两根弹性输液软管2、3分别与两个蠕动泵39、38对位固定。两根弹性输液软管2、3被分别夹紧固定在拱门44的内顶壁与相对应的蠕动泵39、38的滚轮之间，可供滚轮碾压，依靠蠕动泵38、39的动力进行相应的溶配操作。
弹性输液软管2、3具有弹性，以便滚轮碾压过后其能够回复至其 原始形状，以便滚轮进行下一次的挤压，驱动弹性输液软管2、3内的流体流动，进而实现输液容器36和西林瓶37中的药物进行溶配操作。
溶配药器的四根穿刺器28-31的材质为医用不锈钢或医用PVC等医用塑料，以符合医用标准。
溶配药器的两根弹性输液软管2、3皆由医用塑料材质(如：医用PVC、TPE、TPU、医用硅胶等材质)制成。
每个穿刺器基座上的两个穿刺器可设计为具有不同长度或同等长度。如图4所示，穿刺器基座14上具有短穿刺器29和长穿刺器28，穿刺器基座15上具有短穿刺器31和长穿刺器30，其中短穿刺器29和长穿刺器30与弹性输液软管2的两端相连，短穿刺器31和长穿刺器28与弹性输液软管3的两端相连。每个穿刺器基座上实现长短穿刺器的设计配合主要是在双通道动力配合下能够在西林瓶内产生更剧烈的湍流，促进药物溶解。
进一步，短穿刺器31露出穿刺器基座15的部分的长度为8-10mm，以保证西林瓶37内的药液能够尽可能被吸出；长穿刺器30露出穿刺器基座15的部分的长度不长于28mm，不超过2ml的西林瓶37的高度(通常为28mm)，以防止刺裂西林瓶37。
两个基座导槽井22的两侧均开有长度相等的拨针导孔4-7，穿刺器基座14、15上设有拨针穿孔12、13。自动溶配药***的拨针装置穿过拨针导孔4-7并穿入穿刺器基座14、15的拨针穿孔12、13，以拨动穿刺器基座14、15。其中，拨针导孔4-7的长度能使穿刺器基座14、15被拨出后，穿刺器基座14、15的上平面与框架1的上表面达到同一平面，穿刺器28-31随之被拨出基座导槽井22、23并达到其可移动范围的顶点。
穿刺器基座上设有一个或多个滑槽，基座导槽井内设有一根或多根导轨，用于与穿刺器基座上的滑槽配合，以便为穿刺器基座的移动进行导向。
具体地，穿刺器基座14上设有滑槽32、33，基座导槽井22内设有导轨16-18，其中导轨16、17分别与滑槽32、33配合进行导向，导轨18位于两根弹性输液软管2、3之间，也可以进行导向。同样地，穿刺器基座15上设有滑槽34、35，基座导槽井23内设有导轨19-21，其中导轨19、20分别与滑槽34、35配合，导轨19位于两根弹性输液软管2、3之间。
下面结合具体示例说明本实施例的溶配药器进行溶配药的过程。
示例一：粉针、冻干粉针西林瓶装药品的溶配药方案
未进行溶配药时，溶配药器的状态如图1所示。
进行溶配药时，首先通过框架1两边的卡扣将框架1可与卡座相连并卡定。两根弹性输液软管2、3随之分别对位固定在两个蠕动泵39、38上，且两个蠕动泵39、38分别与位于拱门44处的两根弹性输液软管2、3相对应，两根弹性输液软管2、3被分别夹紧固定在拱门44的内顶壁与相对应的蠕动泵39、38的滚轮之间，可供滚轮碾压。
自动溶配药***中的拨针装置穿过拨针导孔4-7，再穿入穿刺器基座14、15的穿孔12、13中，将穿刺器基座14、15沿基座导槽井22、23向外拨动，拨动时与穿刺器基座14、15连接的弹性输液软管2、3在基座导槽井22、23内可被拖动跟随穿刺器基座14、15运动，穿刺器28-31随之拨出基座导槽井22、23，如图2所示。
然后，一端并联的穿刺器28、29可***端口向下的输液容器36内，另一端并联的穿刺器30、31可***端口向下的西林瓶37内。两个蠕动泵39、38同时驱动两根弹性输液软管2、3，将输液容器36内的溶液快速泵入西林瓶37中，泵液的持续时间由智能软件程序控制。泵入结束后，将其中一个蠕动泵38(或39)反向，驱动溶液从西林瓶37内泵入输液容器36中，另一个蠕动泵39(或38)则继续从输液容器36中向西林瓶37内泵入溶液，从而在西林瓶37和输液容器36之间形成循环回流状态，并在西林瓶37内形成激烈的湍流。在溶配过程中，持续剧 烈扰动西林瓶药液和未溶解的药物，且通过输液持续动态的泵入、泵出，使西林瓶37内有限容积的溶液浓度被不断快速稀释，从而使药物加快溶解。药物完全溶解后，两个蠕动泵38、39将西林瓶37内的药液完全泵入输液容器36内，泵液结束后，西林瓶37内的药品溶配操作结束。
溶配药过程完成后，通过拨针装置将两个穿刺器基座14、15拨回至基座导槽井22、23的底部，随之两个穿刺器基座14、15上的穿刺器28-31分别从刺入的输液容器36和西林瓶37中拔出，完成药物溶配过程。
示例二：液体西林瓶配药方案
将框架两边的卡扣与卡座相连并卡定，两根弹性输液软管随之分别对位固定在两个蠕动泵上。
通过拨针装置，将置于框架两端的基座导槽井内的穿刺器基座拨出，随之两个穿刺器基座上的穿刺器同时分别刺入固定在自动溶配药***中的***端口向下的输液容器和西林瓶中。
通过智能软件程序控制，用蠕动泵驱动与西林瓶端的短穿刺器相连通的弹性输液软管，将西林瓶内的药液直接泵入输液容器中；另一通道则在操作过程中提供气压平衡，使药液很容易迅速抽出。泵液结束后，西林瓶内的药品配制操作结束。
通过拨针装置将穿刺器基座拨回，随之两个穿刺器基座上的穿刺器分别从输液容器和西林瓶中拔出，并收回到基座导槽井内，完成配药操作的过程。
上述两个具体实施方案显示，所述溶配过程可进行快速溶配药品的操作并可实现自动化，极大地提高溶配药品的效率，大大降低了医护人员的劳动强度；由于在溶解配制药物过程中，医护人员无需接触，无需反复进行穿刺，配药过程中尽可能减少药物溅出和挥发，有效降低溶配药过程中药物对医护人员的伤害，在溶配药过程中有效减少胶塞颗粒脱 离、外界微粒、微生物的污染，最大限度地降低了药品暴露和药品二次污染，提高了输液安全性，有利于保护医护人员和患者的健康。
本实施例的溶配药器具有如下有益效果：
溶配药器的设计可使其便于安装在自动溶配药***中，进行快速溶解配制药物，提高了效率；
两个穿刺器基座上的穿刺器同时或分别刺入输液容器和西林瓶中，从而形成双通道内联通的封闭***，在溶解配制药物过程中，无需反复进行穿刺，大大降低了医护人员的劳动强度；且医护人员无需接触，无需反复进行穿刺，有效降低溶配药过程中药物对医护人员的伤害，同时降低了药品暴露和药品二次污染，提高了输液安全性，有利于保护医护人员和患者的健康；
通过两个蠕动泵的可控双向驱动，在溶配药过程中提供双动力双向流体(如：液体、气体、液固混合体)输送，在溶配药物过程中，流体在输液容器、西林瓶及两个通道之间可根据需要形成不同的流动方式(如双同向、双反向、内循环)，可在西林瓶内形成激烈的湍流，使西林瓶内药物快速溶解，并能通过内循环的流动方式平衡西林瓶和输液容器内气压，避免人工操作和单通道操作时气压不平衡造成药液抽出注入困难的情况，从而可快速溶配转移药液至输液容器内，使得溶配效率高，溶配药的效果好。
实施例二：
本实施例提供了一种溶配药器，其与实施例一的不同之处在于：其还包括至少一根第二弹性输液软管(未示出)和至少一对第二穿刺器(未示出)，每对第二穿刺器包括两根第二穿刺器，且第二穿刺器的结构与穿刺器28-31的结构相同。
在每对第二穿刺器中，一根第二穿刺器安装在一穿刺器基座14上，另一根第二穿刺器安装在另一穿刺器基座15上，且两根第二穿刺器分 别与一根第二弹性输液软管的两端相连，这样形成了又一个通道。
在每根第二弹性输液软管处均设有蠕动泵，以驱动第二弹性输液软管内的液体流动。
本实施例的溶配药器，其形成了三个或三个以上的通道，使得溶配药的效率更高。
实施例三：
本实施例提供了一种溶配药器，其与实施例一的不同之处在于：
本实施例中的穿刺器基座固定地设置在基座导槽井内移动，不可在基座导槽井内移动。在溶配药的过程中，可移动输液容器和西林瓶，以被穿刺器刺穿。
因此，本实施例中的穿刺器基座上无需设置滑槽、拨针穿孔，框架上无需设置导轨、拨针导孔，弹性输液软管的长度无需设置为可拉伸，可设置成与两穿刺器基座之间的距离相适配，使得溶配药器的结构简化。
需要说明的是，以上实施例仅是本申请的具体的实现方式，还可以存在其他实现方式，如：两个穿刺器基座中，一个是可移动的，另一个是固定的；或任何移动与固定的组合；可通过在框架上设置限位装置来限制穿刺器基座的移动等。
本申请的溶配药器不仅可用于西林瓶的溶配药，还可以用于其他，如两个输液容器等。
在本申请的描述中，术语“多个”指两个或多于两个。
以上公开内容规定为说明性的而不是穷尽性的。对于本领域技术人员来说，本说明书将暗示许多变化和可选择方案。所有这些可选择方案和变化规定为被包括在本权利要求的范围内。本领域技术人员应认识到此处所述的实施方案的其它等效变换，这些等效变换也规定为由本权利要求所包括。
在此完成了对本申请可选择的实施方案的描述。本领域技术人员可 认识到此处所述的实施例仅用于说明本申请，其中溶配药器的元件或结构等都是可以有所变化的，凡是在本申请技术方案的基础上进行的等同变换和改进，均不应被排除在本申请的保护范围之外。
工业实用性
本申请实施例，提高了溶配药品的效率，大大降低了医护人员的劳动强度；医护人员无需接触，无需反复进行穿刺，有效降低溶配药过程中药物对医护人员的伤害，且降低了药品暴露和药品二次污染，提高了输液安全性，有利于保护医护人员和患者的健康。
