 泵门13关门状态下，泵门13将控制按键20按下，止液夹5处于打开状态。 Under the  pump door 13 closed state, the pump door 13 will control key 20 is pressed, the liquid retaining clip 5 is open. 更换或安装输液管100时，打开泵门13，由于失去了泵门13的压力，控制按键20松开，开关2及控制模块控制电机31使止液夹5闭合，输液管100被夹紧从而阻断液路。 When replacing or installing the infusion tube 100, open the pump door 13, due to the loss of pressure of the pump door 13, control buttons 20 release, switch 2 and the control module controls the motor 31 causes the liquid stopper clamp 5 is closed, whereby the infusion tube 100 is clamped blocking the fluid path. 用手按下控制按键20将开关打开，控制模块控制电机31正转，电机31通过减速装置34带动丝杆32正转，螺母33带动滑杆4正向移动，利用导向斜槽40和导向柱50的配合使得止液夹5向远离挡块15的方向滑动，止液夹5逐渐打开；当滑杆4移动至滑杆按键41触发第二位置开关72时，控制模块控制电机31停止转动，此时止液夹5完全打开，如图4、图5所示，可进行取下或安装输液管100的操作。 Hand press the control button 20 the switch opens, the control module controls the motor 31 forward, the motor 31 through the reduction gear 34 driven forward screw 32, nut 33 driven by the slider 4 moves forward, the use of the guide chute 40 and the guide posts 50 with the clip so that liquid only 5 in the direction away from the stop 15 of the slide, was only gradually open the folder 5; 4 when the slider 41 to move the slider button trigger a second position switch 72, the control module controls the motor 31 stops rotating, At this fully open liquid retaining clip 5, as shown in FIG. 4, FIG. 5, can be removed or installed 100. The infusion line.
 安装好输液管100后，松开控制按键20，控制按键20弹起，控制模块控制电机31反转，电机31通过减速装置34带动滑杆4反向移动，滑杆4驱动止液夹5向靠近挡块15的方向滑动，止液夹5逐渐关闭。  installed after the infusion tube 100, release the control buttons 20, 20 pop-up control buttons, the control module controls the motor 31 reverse, the motor 31 through the reduction gear 34 driven by the slider 4 reverse movement, the slider 4 drives stop solution clip 5 in the direction of the slide near the stopper 15, was only 5 gradually close the folder. 当滑杆4移动至滑杆按键41触发第二位置开关72时，控制模块控制电机31停止转动，此时止液夹5完全关闭，如图6、图7所示，输液管100被夹紧。 When the slider 4 to move the slider button trigger 41 second position switch 72, the control module controls the motor 31 stops rotating, then the only solution is completely closed clip 5, 6, 7, the infusion tube 100 is clamped .
 关闭泵门13，泵门13将控制按键20压下，控制按键20将开关2打开，控制模块控制电机31正转，从而驱动止液夹5向远离挡块15的方向滑动，止液夹5逐渐打开。  Close the pump door 13, the pump door 13 20 control buttons pressed, the control button 20 will switch 2 opens, the control module controls the motor 31 forward, thereby driving the liquid retaining clip 5 to slide away from the stopper 15, the stopper hydraulic clamp 5 is gradually opened. 当滑杆4移动至滑杆按键41触发第二位置开关72时，控制模块控制电机31停止转动，止液夹5完全打开，可进行输液作业。 When the slider 4 to move the slider button trigger 41 second position switch 72, the control module controls the motor 31 stops rotating, liquid-only clip 5 is completely open, infusion operations.
 在上述控制模式中，当控制按键20处于松开状态，止液夹5靠近挡块15并处于闭合状态；当控制按键20处于按下状态，止液夹5远离挡块15并处于打开状态。  In the control mode, when the control button 20 in the released state, was only 5 clip close stopper 15 and in a closed state; when the control button 20 is pressed, the folder was only 5 away from the stopper 15 and is open. 即按下和松开控制按键20均可触发开关2，同时控制模块控制电机正转或反转动作一次。 That is, press and release the control button 20 may trigger switch 2, while the control module controls the motor forward or reverse motion again. 更换或安装输液管时，需要用手按下并一直按住控制按键20，控制止液夹5使其保持打开状态。 When replacing or installing the infusion tube, you need to hand press and hold down the control key 20, a control solution only 5 folder to keep it open. 本操作模式与传统的操作模式比较，相同点为都需要用一只手一直打开止液夹5，因此只能有一只手安装输液管100，操作都存在不便之处；不同点是本发明按住的是控制按键20，止液夹5由电机31控制开合，因此操作非常省力，避免了因人力过大而使输液泵倾倒，相对现有的手动机械结构来控制止液夹的方式而言操作非常方便，显著提高了工作效率。 This mode of operation compared with the traditional mode of operation, the same point is we need to use a liquid hand has been open only 5 folder, it can only have one hand to install the infusion tube 100, there is the inconvenience of operation; difference is that according to the present invention, Lived in a control button 20, was only 31 folder 5 by the motor control to open and close, so the operation is very labor-saving, avoiding the excessive manpower leaving the infusion pump dump, opposite the existing manual mechanical structures to control fluid while retaining clip INTRODUCTION operation is very convenient, significantly improve the work efficiency. 同时输液泵工作时泵门13压住的也是控制按键20，因此泵门13不会受到止液夹5的作用力。 At the same time the infusion pump to suppress the pump door 13 is control buttons 20, 13 and therefore will not be liquid pump door stop clip force 5.
 针对上述操作模式操作中的不足，本发明还提供了第二种操作模式以供用户自由选择:按下并松开控制按键20，触发开关2，控制模块控制电机正转或反转一次。  The mode of operation in response to these shortcomings, the present invention also provides a second operating mode for users to choose: Press and release the control buttons 20, trigger switch 2, the control module controls the motor forward or reverse a. 具体方式为:控制按键20被按下并松开，打开开关2时，控制模块控制电机31正转，使止液夹5远离挡块15移动，直到第二位置开关72被触发电机31停止转动，止液夹5完全打开。 Specific way: the control button 20 is pressed and released to open the switch 2, the control module controls the motor 31 forward, away from the liquid retaining clip 5 stopper 15 is moved until the second position of switch 72 stops the motor 31 is activated liquid only clip 5 is completely open. 无需在安装输液管100时用手一直将控制按键20按下，双手均可进行安装输液管100操作，较前一种操作模式更加方便。 Hands-control button 20 has been pressed, the hands can install the infusion tube 100 operation, more convenient than the previous one mode of operation when installing the infusion tube 100. 安装好输液管100后，再次按下控制按键20并松开，并再次触发开关2，控制模块控制电机31反转，使止液夹5向靠近挡块15移动，直到第一位置开关71被触发电机31停止转动，止液夹5完全闭合，完成输液管100的安装，关闭泵门13即可。 After installing the infusion tube 100, control buttons 20 is pressed again and release, and once again trigger switch 2, the control module controls the motor 31 rotates backward to allow the liquid to a near stop clip 5 stopper 15 moves until the first position of the switch 71 is trigger the motor 31 stops rotating, liquid stop clip 5 is completely closed to complete the installation of the infusion tube 100, close the pump door 13 can be.
 以上的实施方式，并不构成对该技术方案保护范围的限定。 Above embodiment , and is not intended to limit the scope of protection of the technology program. 任何在上述实施方式的精神和原则之内所作的修改、等同替换和改进等，均应包含在该技术方案的保护范围之内。 Any modifications within the spirit and principles of the above embodiment made, equivalent replacement and improvement should be included within the scope of the technical solution.
