具体实施方式
本发明实施方式中，所述储液器和输注泵体卡扣连接，各部件模块化生产，安装和拆卸方便，密封性好，下文参考图1-图55进行详细说明和解释。
在本发明实施方式中，输注泵包括储液器112和输注泵体40，储液器112和输注泵体40的形状均为L型；
储液器第一L形侧面1112、储液器长侧面1113、储液器第二L形侧面1114、储液器短侧面1118构成储液器112的侧面，储液器中侧面1116位于储液器长侧面1113和储液器短侧面1118之间，储液器底面1115、储液器低顶面1117均与储液器中侧面1116相邻，储液器低顶面1117位于储液器底面1115与储液器高顶面1121之间；
输注泵体第一L形侧面1122、输注泵体长侧面1123、输注泵体第二L 形侧面1124、输注泵体短侧面1128构成输注泵体40的侧面，输注泵体中侧面1126位于输注泵体长侧面1123和输注泵体短侧面1128之间，输注泵体高顶面1121、输注泵体低顶面1127均与输注泵体中侧面1126相邻，输注泵体低顶面1127位于输注泵体高顶面1121、输注泵体底面1125之间。如图3所述，所述输注泵体与储液器通过滑轨连接结构连接。储液器中侧面1116上设有导轨115、输注泵体中侧面1126上设有轨道114，其中：导轨115与轨道114相互咬合，从而使二者能够相对移动。
导轨115由储液器底面1115向储液器低顶面1117延伸；轨道114由输注泵体高顶面1121向输注泵体低顶面1127延伸；导轨115为弧形，具有第一边缘532；导轨115相对轨道114滑动时，第一边缘532与轨道114相配合。第一边缘532与垂直于储液器高顶面1111的直线的夹角为0.5°-5°，优选1.5°。
导轨115的靠近储液器低顶面1117一端设有限位件531，限位件531位于导轨115与储液器中侧面1116之间的凹槽533内。
储液器112的导轨115用于固定储液器112和输注泵体40。图44为储液器正视图，可见，储液器的两个导轨115(与输注泵体的接触面)与竖直方向的夹角a为0.5°-5°，优选1.5°，所述范围内的角度a能够便于所述储液器和输注泵体互相装配。储液器112的导轨115在底部设有限位件531，所述底部为导轨115靠近储液器低顶面1117的位置。当储液器112和输注泵体40装配时，储液器112会沿着输注泵体40的轨道114向下运动，到底部时，限位件531阻挡储液器112继续相向运动。
轨道114设有向内侧伸出的凸出部543，轨道114具有第二边缘542，轨道114相对导轨115滑动时，第二边缘542与导轨115相配合。第二边缘542与竖直方向的夹角为0.5°-5°，优选0.9°。
轨道114靠近输注泵体低顶面1127一端设有卡紧件，卡紧件在轨道114的底端将轨道114与导轨115卡紧。卡紧件为设于轨道114上的凸起541。
输注泵体40的轨道114用于固定储液器112和输注泵体40。图50为输注泵体正视图，可见，输注泵体40的两个轨道114(与储液器的接触面)与输注泵体中侧面1126的中心线的夹角为优选0.9度，该范围内的夹角方便储液器和输注泵体40互相装配。当储液器112和输注泵体40装配时，储液器112会沿着输注泵体40向下运动，输注泵体40与储液 器112连接越来越紧。输注泵体40的轨道114靠近输注泵体低顶面1127的位置设有卡紧件；快到尽头时，卡紧件与储液器112的接触曲面卡紧。
储液器导轨115和输注泵体的轨道114之间的接触面为曲面，为保证***方便，***过程中，只能是曲面的部分段相接触，在输注泵体40的轨道114的不接触的段的底部设有卡紧件，所述“底部”为轨道114靠近输注泵体低顶面1127的位置。快到底部时，卡紧件与储液器112的导轨115接触，与导轨115卡紧，从而卡接紧固，不易脱开。
本发明实施方式中，在输注泵的初始状态，套筒位于最底端状态。在装配时，使储药器的两个导轨对准输注泵的轨道，从上向下推动，导轨115与轨道114卡紧。
根据本发明实施方式，当储液器和输注泵体装配时，储液器112的两个导轨115对准输注泵体的轨道114，相向推动，两者实现卡合。本发明实施方式中，输注设备组装快捷方便。
输注泵体高顶面1121与储液器低顶面1117通过第一卡扣结构连接，第一卡扣结构包括设于输注泵体高顶面1121的卡钩116、设于储液器低顶面1117的卡口1132，其中：卡钩116与卡口1132相对；卡口1132内侧设有用于与卡钩116卡接的卡销1130，当卡钩116进入卡口1132，卡钩116能够向一侧推开卡销1130，当卡钩116越过卡销1130，向一侧运动的卡销1130能够在恢复力的作用下向另一方向运动，从而使卡钩116与卡销1130钩住。
输注泵体高顶面1121上设有卡钩116、储液器低顶面1117设有卡口1132，其中：卡钩116与卡口1132相对；卡口1132内侧设有用于与卡钩116卡接的卡销1130，卡销1130与设于储液器外壳的侧推钮1131相连。
卡销1130与连杆2383连接，连杆2383与设于储液器外壳240的侧推钮1131相连；侧推钮1131内侧设有与侧推钮1131抵接的弹簧26。
参见图16，卡销1130一侧设有斜面23821，斜面23821朝向卡钩116，在图中呈现为一条线段。当卡钩116进入卡口1132时，卡钩116顶在斜面23821上，从而使卡销1130向远离卡钩116的一侧运动，从而挤压弹簧26。
本发明实施方式中，在输注泵体40的初始状态下，套筒124在最底端。使储液器112的两个导轨115对准输注泵体的轨道114，相向推动， 快到底部位置时，储液器112上面的侧面卡扣238和输注泵体40的卡钩116卡住，从而实现输注泵体40和储液器112的组装。
当储液器112和输注泵体40装配时，输注泵体40的卡钩116从储液器112的卡口1132处触碰到储液器112的卡销1130，如图16所示。侧面卡扣238向右侧移动，当输注泵体的卡钩116穿过储液器112的卡销1130时，向右侧运动的卡销1130会因为弹簧26的弹力转而向左运动，从而使卡钩116与卡销1130钩住，如图17，实现储液器112和输注泵体40的安装。
输注泵还包括底板210，底板210与储液器和输注泵体的组装体29相连。
底板210上设有底板卡扣237，储液器外壳240上设有卡扣入口28，卡扣入口28内侧设有顶端卡扣236，顶端卡扣236设有用于与底板卡扣237扣合的卡爪2363，卡爪2363通过连接件连接至设于储液器外壳240的顶部推钮2361。
连接件为弹簧框2362，弹簧框2362与侧推钮1131的内侧相对，弹簧26位于弹簧框2362与侧推钮1131之间。
顶部推钮2361位于储液器外壳240的表面，储液器外壳240上设有顶部推钮2361和弹簧框2362的连接部位通过的长槽2401，推动顶部推钮2361，该连接部位可沿长槽2401移动。
卡爪2363一侧设有倾斜面23631，当底板卡扣237进入卡扣入口28，底板卡扣237顶在倾斜面23631上，从而使卡爪2363向一侧运动，使弹簧26受到挤压。
如图19、图20所示，底板210上的底板卡扣237触碰到储液器112的顶端卡扣236时，顶端卡扣236向右侧运动，当底板卡扣237向上运动经过顶端卡扣236时，顶端卡扣236由于弹簧弹力向左运动，同时把底板卡扣237卡住，从而实现储液器和输注泵体的组装体29与底板210的装配。
如图20所示，当向右侧(图21向左)推动储液器外壳240上的顶端卡扣236时，顶端卡扣236向右运动(图22向左)，同时顶端卡扣236和底板210上的底板卡扣237分开，储液器112可以和底板210分开，储液器和输注泵体的组装体29和底板210分开。
如图22所示，侧面卡扣238在其被按动的情况下向右运动时，侧面 卡扣238的卡销1130会和卡钩116脱开，从而可使得储液器112与输注泵体分离开。

将输注泵体40的泵底端凹槽235对准底板端凸起239，卡住后，向底板210方向按下输注泵体40，当储液器112和底板210卡住后，实现储液器和输注泵体的组装体29与底板210的组装。
根据本发明实施方式，当储液器112和输注泵体40装配时，储液器112的两个导轨115对准输注泵体40的轨道114，相向推动；同时，储液器112的侧面卡扣238与输注泵体40的卡钩116卡合，使得储液器和输注泵体卡合。将储液器和输注泵体的组装体29中输注泵体40的泵底端凹槽235对准底板端凸起239卡住，向底板210方向按压输注泵体40，从而实现输注设备的组装。因此，本发明的输注设备能够快捷方便地组装。

套筒124外侧设有第二密封件45，第二密封件45为密封圈；输注泵体低顶面1127与储液器底面开口内侧的内壁411之间通过该第二密封件45实现该密封连接。
储液器的导轨和输注泵体的导轨互相咬合后，向下推动储液器112，到达最低端后，储液器112的储液器底面开口内侧的内壁411挤压密封圈，导致密封圈变形，完成装配，如图34所示。图35为装配好后密封圈的剖面状态。
输注泵下壳体19具有与输注泵上壳体11相对接的对接面4411，第一密封件117为设于该对接面4411的密封圈。对接面4411上注塑了一周密封圈，该对接面4411中包括一段弧形部471，弧形部471与对接面4411相适应，对接面4411并不在一个平面上，对接面4411不是平面使连接更牢固，也与下壳体边缘的倾角相适应。上下壳体扣紧后用螺钉固定，密封圈的横截面如图37所示，螺钉使得上下壳体互相挤压达到密封。
