The driving component is connected with the liquid stopping driving part 120 for driving the liquid stopping driving part 120 to move, so that the driving part 123 provides an abutting acting force for the clamping piece 20 to close the clamping piece 20, or the driving part 123 releases the abutting acting force for the clamping piece 20 to open the clamping piece 20. In this embodiment, the liquid stopping driving component 120 is driven by the driving component to move, so that the opening and closing functions of the clamping piece 20 can be automatically controlled, and manpower saving is facilitated.

Specifically, in the process of inserting or pulling the clip 20 into or out of the mounting opening 1121, the driving component is used for driving the driving portion 123 to provide a propping acting force for the clip 20 so as to control the clip 20 to clamp the infusion tube 30 and further achieve liquid stopping, which is beneficial to avoiding the bad phenomenon that the infusion tube 30 is conducted due to the opening of the clip 20 caused by manual misoperation when the infusion tube 30 with the clip 20 is mounted or dismounted on the infusion pump 10.

After the clip 20 is inserted into the mounting opening 1121, the driving component can be used for driving the driving portion 123 to provide a propping acting force for the clip 20, so as to control the clip 20 to clamp the infusion tube 30 and further achieve liquid stopping; and after the clip 20 is inserted into the mounting opening 1121, the driving component can also be used for the driving part 123 to release the propping action force on the clip 20, so as to control the clip 20 to loosen the infusion tube 30 and further realize liquid flowing, that is: after the clip 20 is inserted into the mounting opening 1121, the clip control mechanism 100 can selectively control the clip 20 to open or close, thereby facilitating the control of the liquid stopping and liquid flowing of the liquid conveying tube 30.

Preferably, in the present embodiment, the driving assembly is used for driving the liquid-stopping driving member 120 to swing in the inner cavity 111 to provide the abutting force for the clamping piece 20 or release the abutting force for the clamping piece 20. In this embodiment, the movement of the liquid stopping driving part 120 relative to the supporting structure 110 is set as: the liquid stop driving member 120 is capable of swinging about a fulcrum or a rotation center axis with respect to the support structure 110.

The support structure 110 is further provided with an opening 1131 for the power input part 124 to move, and the power input part 124 extends out of the support structure 110 from the main body part 121 through the opening 1131.

Preferably, the driving assembly includes a first driving mechanism (i.e., the first elastic element 130 in the figure) and a second driving mechanism (not shown), the first driving mechanism is disposed in the inner cavity 111 and connected to the main body portion 121 for driving the main body portion 121 to swing upward, so that the driving portion 123 provides an abutting force for the clip 20; the second driving mechanism is disposed outside the supporting structure 110, and is connected to the power input portion 124, so as to drive the power input portion 124 to move in the opening 1131, so as to drive the main body portion 121 to swing downward, and further drive the driving portion 123 to release the abutting force on the clip 20. Of course, in a specific application, as an alternative embodiment, the second driving mechanism may also be used to drive the main body portion 121 to swing upward, so that the driving portion 123 provides an abutting force for the clip 20; the first driving mechanism is used for driving the main body 121 to swing downwards, and further driving the driving part 123 to release the abutting acting force on the clamping piece 20.

In addition, the infusion tube 30 is clamped without manually operating the clip 20 to stop the infusion when the clip 20 is inserted or pulled out, so that the infusion tube has the characteristics of simple and convenient operation.

Specifically, the power input portion 124 is disposed such that the liquid stopping driving part 120 can rotate against the elastic force of the first elastic element 130 and act against the clip 20 under the action of the second driving mechanism, thereby facilitating the automatic control of the infusion pump 10 on the clip 20.

Preferably, as shown in fig. 4-8, 10 and 12, the power input portion 124 is used for driving the liquid stopping driving part 120 to rotate by the second driving mechanism after the clip 20 is inserted into the mounting hole 1121, so as to compress against the first elastic part 130 and release the infusion tube 30 against the clip 20 to realize liquid infusion; the first elastic element 130 is further configured to drive the liquid-stopping driving element 120 to rotate and abut against the clamping element 20 to clamp the infusion tube 30 so as to stop the liquid when the second driving mechanism releases the acting force on the liquid-stopping driving element 120. In a specific application, before the clip 20 is inserted into the clip control mechanism 100 and during the insertion of the clip control mechanism 100, the clip 20 is in a state of clamping the infusion tube 30 to control the infusion tube 30 to stop infusion; after the clip 20 is completely inserted into the mounting hole 1121, the pump door 300 of the infusion pump 10 is closed, and the second driving mechanism is controlled to start to operate and drive the liquid stopping driving part 120 to rotate, so that the liquid stopping driving part 120 rotates to push against the first elastic part 130 to compress and push against the clip 20 to release the infusion tube 30 to control the infusion tube 30 to start infusion; when the second driving mechanism releases the acting force on the liquid stopping driving part 120, the first elastic part 130 drives the liquid stopping driving part 120 to rotate and push against the clip 20 to clamp the infusion tube 30 so as to control the infusion tube 30 to stop infusion, thus the function of controlling the clip 20 to automatically clamp the infusion tube 30 to stop infusion and releasing the infusion tube 30 to realize liquid infusion by the clip control mechanism 100 is completed, and the bad phenomenon that the infusion tube 30 is conducted due to the fact that the clip 20 is opened in the process of inserting and pulling the clip 20 is effectively prevented.

When the second driving mechanism operates, the power input portion 124 is driven to move in the opening 1131, so as to drive the liquid stopping driving member 120 to rotate. Of course, in certain applications, as an alternative embodiment, the power input portion 124 may not extend out of the support structure 110, but the output component of the second driving mechanism may extend into the support structure 110 from the opening 1131 and be connected with the power input portion 124 to drive the power input portion 124 to move.
