具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。
在本发明的描述中，需要说明的是，属于“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方位或者位置关系为基于附图所示的方位或者位置关系，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，因此不能理解为对本发明的限制。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术 语“安装”、“相连”、“连接”应做广义理解，例如可以是固定连接，也可以是可拆卸连接，或一体式连接；可以是机械连接，也可以是电连接；可以是直接连接，也可以是通过中间媒介间接连接，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
本实施例采用递进的方式撰写。
如图1～6所示，一种安全型药液转移器，包括：本体1和连接件下盖2，本体1上设置有针状体3，针状体3内分别设置有气体通道31和液体通道32；本体1内部设置有与气体通道31联通的排气腔11，排气腔11通过透气阻水膜体12与大气联通；本体1与连接件下盖2之间设置有腔体4，腔体4与液体通道32联通，连接件下盖2具有与注射器连接的连接部21，连接部21处设置有密封结构5，密封结构5在注射器的挤压下形变而联通注射器和腔体4。
如图1～6所示，当有注射器与连接部21连接时，密封结构5自动被压缩，形成联通液体通道32和腔体4的液体转移通道，药液可以经此流入或流出，其中，转移器本体1上的排气腔11和针状体3上的气体通道31也可以平衡在药液转移时内外的气压，透气阻水膜体12阻挡外界污染物进入药液容器。本发明的安全型药液转移器可以使临床配药人员简单、安全地进行配加药工作，包括排气腔11和透气阻水膜体12在内的排气设计可以巧妙地平衡容器内外气压，同时配合密封结构实现密闭式设计可有效防止药液外喷等，避免了药物浪费的同时也保护了配药人员的安全。
作为上述实施例的优选，本体1包括与针状体3连接的安装部13，以及用于实现安装部13的主体结构14，主体结构14的端部设置有向内凹陷的一级台阶面15，台阶面15与连接件下盖2连接，本体1和连接件下盖2可通过粘接或螺旋接头的方式连接在一起。优选方案中提供了一种本体1和连接件下盖2进行连接的方式，因为二者之间需要设置密封结构5，因此此种分体设置的方式可保证密封结构5的安装更加便捷，台阶面15使得二者之间的定位更加精准，从而可确保密封结构5的密封以及密封解除的动作能够更加准确的实现。
其中，主体结构14外围为圆台的环状面，从而提供将转移器与注射器建立连接的施力部分，操作者只需用拇指和食指握持此处的环状面，即可借助环状面的坡度进行施力，从而快速的实现安装。
作为上述实施例的优选，如图7～10所示，密封结构5包括弹性密封垫片51和针刺结构，二者均为旋转体，且与连接部21同轴设置；针刺结构上设置有具有内部贯通通道的刺针52，弹性密封垫片51在注射器的挤压下朝向刺针52运动，刺针52贯穿弹性密封垫片51联通腔体4和注射器，注射器移除时带动弹性密封垫片51远离刺针52；弹性密封垫片51和针刺结构之间设置有集液腔体53。在上述密封结构5使用的过程中，弹性密封垫片51在被刺针52贯穿时，不起到密封阻碍的作用，注射器通过刺针52的内部贯通通道、腔体4和液体通道32实现药液的转移，当注射器的挤压解除时，弹性密封垫片51复位，由于其弹性的特性，被刺针52刺穿的部分会自动的实现封闭而重新建立密封，在其复位的过程中，本优选方案具有 对药液进行收集并将药液封闭在集液腔体53内的功能，具体的，当药液转移完成后，在腔体4和液体通道32内必然残留少量药液，由于排气腔11和透气阻水膜体12的设置，此部分药液会在药液转移器进行后续处理的过程中而流淌出来，从而给相关人来带来安全威胁，然而本发明中，当刺针52与弹性密封垫片51接触后，集液腔体53即实现密封，而在弹性密封垫片51被注射器挤压的过程中，集液腔体53内的压力提高，此种压力的提升会在注射器移除后形成负压而通过刺针52的内部贯通通道对残留在腔体4和液体通道32内的少量药液进行吸取，并将吸取的药液封锁在集液腔体53内而避免泄露。
在实际使用的过程中，由于残留的药液量较小，因此在快速被吸取至集液腔体53内后可快速的对刺针52的端部进行液封。优选刺针52的贯通通道的流通面积与液体通道32的流通面积相等，或者刺针52的贯通通道的流通面积大于液体通道32的流通面积。
在注射器与药液转移器进行连接的过程中，弹性密封垫片51贴合于注射器端部可实现密封，为了进一步的提升密封效果，如图11～13所示，弹性密封垫片51包括具有凹槽的碗状主体51a，以及设置于碗状主体51a槽体底部的凸起51b，凸起51b与碗状主体51a同轴设置，凸起51b在与所述注射器连接的过程中插入所述注射器端部。在注射器与药液转移器连接的过程中，凸起51b插入注射器端部的孔位内实现密封，二者之间密封连接后，可更加有效的进行药液的转移。
如图14所示，作为上述实施例的优选，凸起51b自与碗状主体51a的 连接处逐渐成收缩状延伸，从而可对注射器进行导向，使得注射器与凸起51b更好的对接，注射器嵌入碗状主体51a的槽体内，也更加便于施力，使得弹性密封垫片51快速的被刺针52刺破而实现药液的流通。
通过上述凸起51b的设置，还具有另外一个作用，即在注射器与弹性密封垫片51分离的过程中，可通过与弹性密封垫片51之间的摩擦力将凸起51b自刺针52上有效的移除，避免漏液情况的发生。
作为上述实施例的优选，碗状主体51a的侧壁为曲面结构，在弹性密封垫片51被挤压的过程中，曲面结构的设置使得凸起51b获得更大的移动空间，保证刺针52有效的刺穿凸起51b，同时曲面的结构具有较大的弹性，此种弹性可在注射器自药液转移器移除的过程中保证凸起51b与注射器更好的贴合而自刺针52上移除。
针刺结构包括安装板54和突出于安装板54表面的固定结构55；刺针52安装于安装板54上，固定结构55对弹性密封垫片5边缘上所设置的凸沿51c进行挤压固定。通过安装板54和固定结构55的设置，以及固定结构55对凸沿51c的挤压固定，可使得安装板54、固定结构55和弹性密封垫片51可形成稳定的结构，此种相对整体式的结构在安装的过程中更加方便。当主体结构14的端部设置有向内凹陷的台阶面时，可通过台阶面对安装板54的挤压实现固定。
作为上述实施例的优选，固定结构55为桶状结构，且与连接件下盖2内壁贴合，从而对凸沿51c的全范围进行挤压定位，避免集液腔体53内液体的渗漏。
如图3所示，针状体3外套设有安全护套6，安全护套6端部与安装部13相抵，安全护套采用的橡胶或硅胶材料，安全护套6在使用前后均可以避免医护人员的针刺伤。
本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
