具体实施方式
以下结合附图，对本发明上述的和另外的技术特征和优点作更详细的说明。
一种溶药器，其包括外套，用于提供容纳药剂的空腔，所述外套一端设有卷边，所述外套另一端设有锥头。这样，可以通过卷边与外置设备组合，便于配药。
实施例1
在配药的时候，配药人员(如护士等)每天需要配置多大上千份的药物，每份药物都需要更换新的溶药器，因此溶药器与手柄需要能够快速插拔，且密封结合。
溶药器在配药的时候，需要通过后续的手柄进行气动驱动，驱动时的气动压强比较大，溶药器与手柄的结合端一般都具有缝隙(互相之间没有密封)，驱动时的高压强会使得溶药器内的气体高速从缝隙冲出，容易造成损伤或者无法驱(溶药器)。
如图1所示，一种溶药器，其具有外套1、所述外套上设有锥头2，所述外套具有空腔，所述锥头设置在所述外套上，且与所述空腔连通，所述外套的后端面上具有凸起3，所述凸起形状封闭。
这样，所述外套与外部物体连通时，所述凸起与外部物体接触并紧贴，使得所述凸起与外部物体成密封结构，对凸起的内部空间进行密封，防止外套与外部物体之间的接触位置漏气。
如图2A所示，该凸起为圆形凸起；
如图2B所示，该凸起为方形凸起；
如图2C所示，该凸起为椭圆形凸起；
如图2D所示，该凸起为星型凸起；
由图2-图5中可以看出，该凸起的形状可以为任何形状，只要其形状密封(所谓形状密封，是指该凸起的内部空间与外部空间被该凸起隔断，没有相连)，就可以与外部物体构成密封结构，防止外套与外部物体之间的接触位置漏气，从而达到比较好的密闭效果。
实施例2
如实施例1所述的溶药器，本实施例与其不同之处在于，如图2A所示，所述溶药器的凸起3的形状与所述外套的横截面相同，这样凸起3的内壁与外套的内壁贴合且相同，防止因凸起3产生外套的内壁不平，对放入其中的胶塞的运动产生阻碍。
所述溶药器的外套的横截面和凸起3可以是圆形的，也可以是椭圆形的，也可以是星型、锯齿形等其他形状(具体实施时可以根据实际需要进行选择或设计)，只要外套的横截面和凸起3的形状相同即可。
优选地，所述溶药器的外套的横截面和凸起3为圆形，这样，生产方便，且便于旋拧溶药器。
本实施例中，所述凸起3与外部物体可以为平面接触并密封，这样在密封时，所述凸起3的顶端挤压外部物体的接触平面，以达到密封效果；这样，所述凸起3的设置减少了溶药器外套的后端与外部物体的接触面积，提高了外套与外部物体相互挤压的压力，从而提高了密封性；另外，凸起3的设置减少了旋转溶药器时产生的摩擦力，便于溶药器的旋转卡接；这样，只需要凸起3与外部物体接触的位置(外部物品)为平整的，与外部物体的边沿不接触，就可以实现密封。其中，如图3A、图3B、图3C所示，凸起3的顶端可以为锐角、椭圆、钝角形，这样密封更加牢固。
本实施例中，所述凸起3与外部物体可以为边沿接触并密封，外部物体具有孔洞，所述凸起3插入所述孔洞并与所述孔洞的内边沿挤压密封；这样，密封效果更好。其中，如图3D所示，所述凸起3的顶端为圆心向外的圆弧状，这样便于与孔洞的内边沿挤压密封；如图3B所示，所述凸起3的顶端也可以为圆心向内的圆弧状，这样便于加工；所述凸起3的顶端也可以为图3E中所示的形状，只要其可以与孔洞的内边沿挤压密封即可。
实施例3
为了完成无菌配药，不仅需要在配药的过程中保持溶药器外套空腔内的无菌环 境，在更换溶药器时也需要使得能够将溶药器内的细菌置换掉。本发明中主要通过在手柄的前端设置过滤器，从中吹出均匀、分散、不交叉的同向气源/洁净气流，对手柄前端空气进行置换，以达到局部百级的洁净度，以保证更换环境的无菌。同时，对于溶药器胶塞后端的细菌，通过均匀、分散、不交叉的同向气源/洁净气流进行吹拂，将其中的细菌置换出去。但是目前的溶药器中，细菌潜藏较多，很难通过单纯的均匀、分散、不交叉的同向气源/洁净气流进行吹拂将细菌吹出(置换出去)。
一种胶塞，其中，所述胶塞4的后端面为平面。这样，细菌就无法潜藏在胶塞的后端面上，从而通过单纯的均匀、分散、不交叉的同向气源/洁净气流进行吹拂就可以将细菌吹出(置换出去)。
实施例4
如上述所述的胶塞，本实施例与其不同之处在于，如图4所示，所述胶塞4为实心胶塞，这样，生产方便，且强度足够，便于通过气动方式进行驱动；且后端面为平面，便于将后端面细菌置换出去。
实施例5
如上述所述的胶塞，本实施例与其不同之处在于，如图5所示，所述胶塞4包括胶塞套41和芯杆42，所述芯杆42前端插入所述胶塞套41，且所述芯杆42后端具有后端盖421，所述后端盖421后侧为平面且所述后端盖紧贴所述胶塞套41。这样，使用方便，便于通过气动方式进行驱动；且后端面为平面(后端盖421后侧)，便于将后端面细菌置换出去。
所述实施例4和实施例5中的胶塞为实施例3中胶塞的两种不同形式，也可以为其他形式的胶塞，只要其可以满足后端面为平面，细菌就无法潜藏在胶塞的后端面上，从而通过单纯的均匀、分散、不交叉的同向气源/洁净气流进行吹拂就可以将细菌吹出(置换出去)。
实施例6
如上述所述的胶塞，本实施例与其不同之处在于，如图6A所示，所述胶塞4侧边具有环形槽43，以便于对胶塞的位置进行限定。
如图6B所示，所述环形槽43设置在所述胶塞4的前端；该环形槽43也可以设置在所述胶塞4的中间或者胶塞的后端；这样设置，不仅可以在通过环形槽43对胶塞的位置进行限定，还减少了胶塞与溶药器外套的接触面积，减小了胶塞移动时受到周围外套的阻力，增加了胶塞的流畅度。
如图6C所示，所述环形槽43的数量为两个，这样，可以进一步减少胶塞与溶 药器外套的接触面积，增加流畅度。
实施例7
如上述所述的溶药器，本实施例与其不同之处在于，所述溶药器的外套1的内壁上，具有限位端，对胶塞4的位置进行限定。
如图7所示，所述限位端为环绕在所述外套1内壁上的环形内凸起11，所述环形内凸起11卡入所述环形槽43内，对胶塞4的位置进行限定。
较佳的，所述环形内凸起11的宽度与所述环形槽43的宽度相同，这样需要对胶塞的位置进行限定时，环形内凸起11恰好卡入所述环形槽43内，限位胶塞。
所述环形内凸起11设置在所述外套1后部，这样可以将胶塞固定所述溶药器的后端，这是由于无菌配药时，为了在更换溶药器时能够将溶药器内的细菌置换掉，需要在更换溶药器时，溶药器的胶塞后端与外套的后端面平齐，这样才能在均匀、分散、不交叉的同向气源/洁净气流的吹拂下将细菌吹出(置换出去)，如果溶药器的胶塞位于外套的中部，那样在胶塞与外套后部形成了柱状的凹陷，均匀、分散、不交叉的同向气源/洁净气流吹入该凹陷处时，会产生乱流在该凹陷处进行交叉混合，这样就无法将凹陷处的细菌吹走(置换出去)。
如图8所示，所述环形内凸起11将所述胶塞限位在所述外套后端，且所述胶塞后端面与所述外套凸起3的后端面平齐，这样，使得溶药器的后端面为平面，便于将其上的细菌置换出去。
较佳的，所述胶塞后端面与所述凸起3内侧相配合，从而防止所述胶塞设置在所述溶药器后端时，所述胶塞后端与所述凸起3后端产生缝隙，隐藏细菌，无法被置换出去。
实施例8
如上述所述的溶药器，本实施例与其不同之处在于，所述溶药器具有卷边12，所述卷边12设置在所述外套1上且向所述外套1外侧延伸；这样，便于对所述溶药器进行固定。
所述卷边12为两个，且对称设置在所述外套1上，这样可以加强卷边12与外套1的强度。
如图9所示，所述卷边12设置在所述外套1中部；实际上，所述卷边也可以设置在外套1后部或者前部，只要可以通过卷边12对外套1进行固定即可。
所述卷边12可以为一个，也可以为多个对称设置在外套1上；这样，可以加强卷边12与外套1的强度。
所述卷边12与外套1的后端面平齐，这样便于生产，且防止所述外套1的后端面部分出现凹槽，无法置换其中隐藏的细菌等污染物。
实施例9
如实施例1所述的溶药器，本实施例为与其对应的手柄5，如图10所示，所述手柄5上设置有弹性件61，所述弹性件61与所述外套后端的凸起3配合，形成密封结构。
这样，在所述凸起与所述手柄的内部空间进行密封，防止外套与手柄之间的接触位置漏气。
所述弹性件61上具有孔洞，所述孔洞通过所述凸起3与所述外套内的空腔连通。
如图11所示，所述弹性件61可以为圆形，也可以为方形，也可以为椭圆形，也可以为星型；所述弹性件61内孔洞的形状也可以为圆形，也可以为方形，也可以为椭圆形，也可以为星型；所述孔洞的形状与所述弹性件61的形状可以相同，也可以随机组合；所述弹性件61可以与所述凸起的形状对应，这样便于结合，也可以与其不对应，只要弹性件61与所述凸起3结合部分无空隙(所述无空隙是指弹性件61与凸起3接触并紧贴的部位无空隙，这样弹性件61与凸起3紧贴后可以在结合部位达到密封效果)，即可达到比较好的密封效果。
优选的，所述弹性件61的孔洞为圆形，这样便于溶药器旋转密封。
优选的，所述弹性件61为弹性圆环(即弹性件61的形状、所述弹性件61的孔洞均为圆形)，这样加工方便。
实施例10
如上述所述的溶药器及手柄，本实施例与其不同之处在于，所述凸起3与弹性件61的前端面平面接触并密封，这样在密封时，所述凸起3的顶端挤压弹性件61的前端面，以达到密封效果；这样，所述凸起3的设置使得外套的后端面与弹性件61的前端面不直接接触，减少了溶药器外套的后端与弹性件61的前端面的接触面积，提高了外套与弹性件61的前端面相互挤压的压力，从而提高了密封性；另外，凸起3的设置减少了旋转溶药器时产生的摩擦力，便于溶药器的旋转卡接；这样，只需要凸起3与外部物体接触的位置为平整的，与外部物体的边沿不接触，就可以实现密封。
本实施例中，所述凸起3与弹性件61的前端面也可以为边沿接触并密封，所述弹性件61的孔洞为圆形，所述凸起3插入所述弹性件61的圆形孔洞并与所述孔 洞的内边沿挤压密封；这样，挤压部位的形变量更大，密封效果更好。
实施例11
如上述所述的溶药器及手柄，本实施例中，如图12、图13、图14所示，所述手柄还包括：安装槽73，所述安装槽73与所述溶药器的卷边12配合，将溶药器安装固定在手柄5上。
这样，可以通过安装槽将溶药器直接安装固定在手柄5上，简单方便，便于对溶药器进行快速安装。一般情况下，护士的配药需要每天配置数千次，这就需要对溶药器进行安装和拆卸时方便快速，且安装牢固。
所述安装槽73为圆形槽，其靠近前端的一侧壁74开口，所述卷边12经所述开口插入所述圆形槽，旋转后卡接在圆形槽中。这样，安装简单，拆卸时旋转至初始位置后可以将卷边12从圆形槽中取出，拆卸方便，快速，便于更换溶药器。
所述开口从所述圆形槽的侧壁74边缘延伸至中心，且延伸的一端形成与所述溶药器外套1直径相同的圆形凹口75，这样所述卷边12插入所述圆形槽后，所述溶药器的外套卡入圆形凹口75中，外套的轴心与所述圆形凹口75的圆心重合，然后旋转外套1，卷边12在圆形槽内沿外套1轴心转动，从开口处转入圆形槽内，从而将卷边12卡住。这样，圆形凹口75对溶药器的外套进行定位，方便旋拧，且方便卷边12卡入(否则会出现防止不正确，导致卷边12与圆形槽对应不上，无法卡接的问题)。
所述安装槽73(圆形槽)内设置有阻挡端(图中未画出)，对旋转后的卷边12进行限位，防止所述卷边12旋转过渡，使得卡接不稳固或者卷边12从圆形槽中旋出(旋转180度后会从中旋出，旋转较大会使得卷边12卡接的部分过少，不够稳固)。
所述手柄5前端部51向前伸出，这样便于握持。
所述前端部51内侧为弧形凹槽，与所述外套1的外壁弧度相同，这样前端部51内侧与外套1的外壁配合，便于外套1贴合前端部51；且这样在握持手柄时，一部分握持在前端部51的外侧，一部分握持在外套1的外侧，将外套1向前端部51的内侧挤压，从而对溶药器进行固定。
所述安装槽73设置在所述前端部51后侧，所述前端部51内侧靠近所述安装槽73处设置有卷边槽76，所述卷边槽7,6一侧与所述安装槽73的侧壁74抵靠，且所述卷边槽76与所述圆形凹口75平齐，这样可以将卷边12放置在卷边槽76中向后推动，经过圆形凹口75后将卷边推入圆形槽内；推动方便，且便于对溶药器 后端的细菌进行置换。
所述手柄还包括：
过滤器62，其对流经的气体进行过滤，将其过滤为洁净的气体，所述过滤器62通过快锥头63与主机的气道联通。
这样，可以对吹入溶药器的气流进行过滤，且通过快锥头63进行连接，可以快速插拔，便于更换过滤器。
过滤器62的出气口设置有多个等径小孔，这样使得过滤器的出气口处为均为、不交叉的平稳气流，便于对前端进行净化。
过滤器62包括出气壳621、进气壳622和过滤膜623，出气壳与进气壳固定连接，过滤膜623设置在出气壳和进气壳之间的空腔内。
进气壳622呈锥状，其内壁上均匀设置有加强筋，用于提高进气壳622强度，并与出气壳621配合以夹持过滤膜623，洁净空气由锥状进气壳622小口进入。
出气壳621为与进气壳622大口相配合的圆形扣盖结构，并扣接在进气壳622上；出气壳621上设置有一定数量的等径小孔作为出气口，可以使气流面积增大，并且各出气口分布均匀，能够提供较为缓慢、均匀、互不交叉、无涡流无乱流的大面积洁净气体，过滤器出气壳直径为2.5cm，可以产生直径2.5cm的气束，以将出气口前端置换为洁净环境，达到局部无菌的效果；出气壳621的表面为平面，即出气壳621上，除去出气小孔外的表面均处于同一平面，不存在凸起或者沟槽，以避免产生涡流和死角，防止被污染物附着，进而保证无菌环境；出气壳621靠近进气壳622一侧设置有加强筋，用于提高出气壳621强度，并与进气壳622配合以夹持过滤膜623。过滤器上加强筋的设置，在提高了整体强度的同时，还对中间的过滤膜623进行夹持，防止膜破裂，提高了过滤效率。出气壳621的加强筋数量为2个，也可以设置1个或者多个，进气壳622的加强筋数量为6个，当然也可以设置少于或者多于6个，灵活设置不同数量的加强筋，以达到不同设计下的不同要求。在本实施例中，出气壳621和进气壳622上的加强筋都为一字型，当然也可以采用带有弧度或角度的其他形状，即加强筋的形状也可根据实际需求作具体设定。
过滤膜623设置在出气壳621和进气壳622之间，本发明中的过滤膜623采用0.22mm孔径的聚四氟乙烯材质的滤膜，这种滤膜使用普遍且成本低，其孔径尺寸是无菌过滤的阈值，可以很好的起到过滤气体的作用。
向过滤器吹气时，进气壳622做为进气口，出气壳621作为出气口，气体从进气壳622的小口进入，经过过滤膜623的过滤，成为洁净气体后，从出气壳621的 各个小孔吹出，从出气壳621吹出的的气束直径可达2.5cm，增大了出气面积，并气流缓慢、均匀、互不交叉，且无涡流无乱流，能够将出气壳621前端的区域置换为洁净无菌的环境，以达到局部百级洁净程度。
本发明的过滤器结构简单合理，其出气壳621采用带有小孔的圆形扣盖，减小了气体流过本过滤器的阻力，且能够提供均匀、缓慢、不交叉、大面积的洁净空气，达到过滤器前端局部洁净无菌的效果，且过滤效率高、效果好。
手柄5还包括：固定件64和卡接件65。弹性件61与过滤器的出气壳621贴合，卡接件65的形状与过滤器8相适应，过滤器设置在卡接件65中，固定件64直接顶扣在卡接件65上。将溶药器安装到手柄上时，溶药器的后端到达固定件64的位置时，溶药器的凸起固定至弹性件61中，将溶药器旋转90度，溶药器尾部在弹性件61内转动，弹性件61不随溶药器尾部一起转动，以完成溶药器与手柄的安装固定。
快锥头63为双头快锥头，双头快锥头一端通过连接卡接件65连接过滤器，另一端连接封闭气管，这样易插拔，且密封性好。
本实施例的手柄通过气管和电源线和气源输出装置连接，将溶药器安装到手柄前，气源输出装置向手柄供应小动力气源，小动力气源通过气管进入进气壳622，经过过滤膜623的过滤，得到洁净无菌的气体，过滤后的气体经过出气壳621，从出气壳621的出气小孔吹出，得到提供均匀、缓慢、不交叉、大面积的洁净空气，能够将出气壳621前端的区域置换为洁净无菌的环境，以达到局部百级洁净程度；将溶药器安装到手柄时，保持手柄前端吹供小动力气源，将手柄前端区域置换为洁净无菌环境，将溶药器贴合于手柄前端内侧，手持挤压溶药器靠向手柄，并向过滤器方向推进，推进至距手柄前端较近位置时，停留1-2秒后继续推进溶药器，以确保小动力气源将溶药器末端吹至无菌，直至手柄前端凹槽处，溶药器与密封固定件的过滤机头内的弹性件61固定，旋转所述溶药器，完成将溶药器固定在所述手柄上，此时停止向手柄供应小动力气源，由按键控制气路输出装置向手柄吹气和抽气，以进行配药。
所述手柄还包括O形圈66，O形圈66设置在过滤器和弹性件61之间，用于防止硬磨，且起到缓冲的作用。
弹性件61顶扣在过滤器的出气壳621上，弹性件61和过滤器之间设置有O形圈7，O形圈7的中间直径与溶药器保持一致，设置为2cm。用于防止硬磨，且起到缓冲的作用，进而增加弹性件61的使用寿命，
固定件64后端与卡接件65前端卡接，从而将弹性件61，O形圈66,过滤器62卡接在内，形成以整体，这样便于整体更换。
所述手柄的外壳通过卡扣连接，这样便于将外壳打开，更换其中的过滤器。
所述安装槽73设置在所述固定件64上。
实施例12
如上述所述的溶药器与手柄，本实施例为一种溶药器位置测定装置，其包括溶药器和手柄，其中，所述溶药器上具有一标识部，所述手柄上具有一测定部，所述测定部在所述标识部靠近后产生变化信号，对所述溶药器位置进行测定。
这样，当将溶药器到达指定位置后，标识部正好靠近所述测定部，该测定部产生信号变化，后续的主机通过该信号变化确认溶药器到达指定位置，从而对气体流速进行控制。
正常的溶药器从无菌包装中拿出时，其后端会与外界有菌空气接触，沾染上细菌等污染物；在将溶药器安装到手柄上时，需要对手柄的前端和溶药器的后端进行置换，将其中的细菌等置换出去。我们采取的方式是通过后部设置气源输出装置(主机)，以提供气源方面的动力输出，以及净化空气方面的动力输出，这样，在安装溶药器时，从手柄中间的孔洞处(出气口)吹出洁净、不交叉的气流，这些气流由于比较差，且持续不断从孔洞处吹出，可以将手柄前端的细菌等污染物逐渐带出，在手柄前端形成无菌的环境；同时，安装溶药器时，将溶药器逐渐靠近手柄前端，则溶药器后端进入手柄前端的无菌环境时，洁净、不交叉的气流会吹到溶药器后端，从而通过持续不断的吹拂，将溶药器后端的细菌等置换出去(为了达到更好的置换效果，可以将溶药器的后端在靠近手柄后停留一段时间)。但是置换细菌的气流流速需要缓慢，以防止气流与手柄孔洞的内壁接触后产生涡流等乱流(乱流会导致气流内部交叉，这样对周围环境的净化很差)，同时对溶药器的胶塞进行驱动时，需要短时间内对胶塞后端的压强进行较大的变化，这就需要急速的气流，两种气流之间需要在溶药器安装到手柄上时进行切换，这就需要对溶药器是否到位进行检测。
另外，溶药器的安装需要快速，但快速安装意味着安装容易出错，一旦出错，容易对外界或者手柄造成损伤，此时，该位置检测装置只有在溶药器安装到位后才会产生信号变化，将慢速的洁净气流更换为高速的洁净气流作为动力，防止溶药器安装不到位时高速气流产生损伤。
实施例13
如上述所述的溶药器位置测定装置，本实施例与其不同之处在于，如图15所 示，溶药器上具有一遮光带13，手柄上具有一光电传感器71，所述光电传感器与所述遮光带配合，对所述溶药器的位置进行测定。安装溶药器时，遮光带靠近光电传感器，在安装到位后，所述遮光带遮住光电传感器之间的光线(图中为了将遮光带表现出来，将溶药器旋转了180度)，使得光电传感器之间的光线断绝，从而使光电传感器信号发生变化，使得气流速度发生变化。配药完毕后，拆卸溶药器时，遮光带离开光电传感器，使其信号恢复，使得气流速度恢复；这样，可以对溶药器是否安装到位或拆卸完成进行检测，便于对气流进行控制；另外，在配药过程中，若溶药器倾斜或掉出，遮光带会离开光电传感器的位置，使光电传感器信号发生变化，这样可以提示使用者溶药器的状况，防止在溶药器倾斜后继续配药，使外接细菌进入溶药器的后端。
溶药器用于配药，其锥头2设置在外套的前端，且锥头位于所述外套前端面的边缘位置，并非出于中央位置(这是由于国家对配药用的溶药器规定)，所述遮光带13设置在所述外套1的外壁上，与所述锥头在所述外套的横截面上的投影相对(即他们的投影位于外套中心的两侧)，这样在与手柄结合时，所述遮光带靠近所述手柄伸出的一侧，与所述光电传感器71配合，所述锥头远离所述手柄伸出的一侧，便于配药。
所述溶药器的刻度设置在外套上靠近所述遮光带13的一侧，这样可以读数。
优选地，所述溶药器的刻度设置在外套上遮光带13和锥头的中间，这样配药时可以从侧面清晰地读出刻度。(设置在所述遮光带13的一侧，安装时手柄突出的一侧会将刻度遮挡大半，不便于读数)。
实施例14
如上述所述的溶药器位置测定装置，本实施例与其不同之处在于，如图16所示，所述溶药器的标识部为所述卷边12，所述手柄的前端面设置有触发端72，所述触发端与所述溶药器的卷边12位置对应，这样，安装溶药器时，卷边靠近手柄，并抵住触发端，该触发端被抵住后发出到位信号，对溶药器位置进行测定。
这样，设置方便，便于触发。
触发端可以为微动开关，这样触发方便。
实施例15
如上述所述的溶药器位置测定装置，本实施例与其不同之处在于，所述溶药器的标识部为所述卷边12，所述手柄的前端面设置有触发端72，所述触发端与所述溶药器的卷边12旋转90度的位置对应，这样，安装溶药器时，卷边靠近手柄，旋 转90度后抵住触发端，该触发端被抵住后发出到位信号，对溶药器位置进行测定。
这样，设置方便，便于触发；且可以在溶药器安装到位或拆卸或倾斜时发出产生信号变化，使使用者可以清楚了解溶药器状态。
触发端可以为微动开关，这样触发方便。
实施例16
如上述所述的溶药器位置测定装置，本实施例与其不同之处在于，所述溶药器上设置有磁铁14，所述手柄的对应位置处设置有磁铁感应器，所述磁铁与所述磁铁感应器配合，对所述溶药器的位置进行测定。安装溶药器时，磁铁向磁铁感应器运动，在安装到位后，所述磁铁接触(或接近)所述磁铁感应器，使得磁铁感应器信号发生变化，使得气流速度发生变化。配药完毕后，拆卸溶药器时，磁铁远离磁铁感应器，使其信号恢复，使得气流速度恢复；这样，可以对溶药器是否安装到位或拆卸完成进行检测，便于对气流进行控制；另外，在配药过程中，若溶药器倾斜或掉出，磁铁会远离磁铁感应器，使磁铁感应器的信号发生变化，这样可以提示使用者溶药器的状况，防止在溶药器倾斜后继续配药，使外接细菌进入溶药器的后端。
其中，磁铁感应器感应磁铁的范围可以根据实际情况进行设定。
实施例17
如图17所示，本实施例为一种无菌配药系统，其包括：
上述所述的溶药器，
主机9，其用以提供气源动力输出；
上述所述的手柄5，其后端与所述主机9通过管道连通(图中未画出)，并对所述主机的气源输出进行控制。
这样，安装前，打开主机(气源输出装置)，主机通过管道向手柄输出小流速的气流，该气流经过手柄中的过滤器过滤后，成为洁净、不交叉的洁净气流从手柄前端吹出，对手柄前端进行净化，将其置换为无菌环境；安装溶药器时，将溶药器后端靠近手柄并进入无菌环境，使得洁净气流吹拂在溶药器后端并停顿一段时间，将溶药器后端置换为无菌的；然后将溶药器安装在手柄上，触发手柄上的标识部，使得标识部信号发生变化，该变化控制主机停小气流的输送；配药时，按动手柄上的前进键，控制主机向外输出大气流，将溶药器中的胶塞前推，将溶药器中的药液挤出；按动手柄的后腿键，控制主机向外抽取大气流，将溶药器中的胶塞后移，将药瓶中的药液吸入溶药器中；配药完毕后，将溶药器从手柄上取下，手柄上的标识部信号发生变化，控制主机向外输出小气流，手柄前端置换为无菌环境，直安装新 的溶药器，进行新一轮配药。
实施例18
如上述所述的溶药器，本实施例与其不同之处在于，如图18所示，为本实用新型实施例18的溶药器的结构示意图。如图19所示，为本实用新型实施例18的用于配药系统的溶药器的使用状态示意图。本实施例提供的一种用于配药系统的溶药器包括外套1，外套1一端设有卷边813，另一端设有锥头12。卷边813与净化装置84采用螺纹连接或卡扣连接或爪钩连接或旋扣连接或磁力连接。锥头12与针头82采用螺纹连接或卡扣连接或爪钩连接或旋扣连接或磁力连接。胶塞4内置于外套1。胶塞4在外套1内轴向运动。胶塞4将外套1分隔成第一腔体811和第二腔体812。制作胶塞4所使用的材料为耐高温且具有生物安全性的硅橡胶。
净化装置84通过接头85与气体输出单元89连通，净化装置84内部还设置气体管路86，气体管路86一端与接头85连通，另一端与第二腔体812连通，气体管路86上设有空气过滤器87，空气过滤器87用于过滤来自气体输出单元89的气体。
净化装置84与卷边813连接处设有密封圈88。气体管路86与外套1连通一端的截面积小于胶塞4的截面积，其好处在于，防止胶塞4脱离外套1而进入气体管路86内。
本实施例的工作原理为：
将外套1与净化装置84密闭连接，连接后，气体输出单元89向气体管路86内压入空气，由于气体管路86与第二腔体812连通，因此第二腔体812内气压升高，当第二腔体812内的气压高于第一腔体811时，第二腔体812内的高压气体推动胶塞向靠近针头82方向运动。将第一腔体811内的空气全部排出，当第一腔体811内的空气全部排出时，将针头82插入液体药剂瓶中，然后通过气体输出单元89将第二腔体812内的气体吸出，当第一腔体811内的压力大于第二腔体812内的压力时，胶塞4向靠近净化装置84方向运动，将药液吸入第一腔体811内。然后移除液体药剂瓶，再将针头82插入冻干粉药剂瓶中，控制气体输出单元89向气体管路86内压入空气，当第二腔体812内的气压高于第一腔体811时，第二腔体812内的高压气体推动胶塞向靠近针头82方向运动，使第一腔体811内的药液流入冻干粉药剂瓶中，待药液与冻干粉充分混合后，通过气体输出单元89将第二腔体812内的气体吸出，当第一腔体811内的压力大于第二腔体812内的压力时，胶塞4向靠近净化装置84方向运动，进而，将冻干粉与药液的混合物抽取至第一腔体811内，完成融药。
溶药器工作过程中，由于气体管路86上设有空气过滤器87，因此流入第二腔体812内的空气为净化后的无菌空气，防止外套1内部遭受污染，使融药过程更加安全。
以上所述仅为本发明的较佳实施例，对本发明而言仅仅是说明性的，而非限制性的。本专业技术人员理解，在本发明权利要求所限定的精神和范围内可对其进行许多改变，修改，甚至等效，但都将落入本发明的保护范围内。
