[0042] In the embodiment, the guiding and clamping member comprises a first guiding and clamping member 21 and a second guiding and clamping member 22, the input section comprises a first input section 31 and a second input section 32, the containing groove comprises a first containing groove and a second containing groove which are arranged at intervals, the first guiding and clamping member 21 is installed between the first input section 31 and the second input section 32, the second guiding and clamping member 22 is installed between the second input section 32 and the output section 33, the first guiding and clamping member 21 and the second guiding and clamping member 22 are located in the first containing groove and the second containing groove respectively; by arranging the first guiding and clamping member 21 and the second guiding and clamping member 22.

[0043] Specifically, the detection device comprises a Hall detection plate 50 and a magnetic ring 23, the first guide clamping part 21 is provided with the magnetic ring 23, the Hall detection plate 50 detects whether the magnetic ring 23 is located in the first accommodating groove; and / or the second guide clamping part 22 is provided with the magnetic ring 23, the Hall detection plate 50 detects whether the magnetic ring 23 is located in the second accommodating groove; the Hall detection plate 50 detects whether the guide clamping part with the magnetic ring 23 is located in the corresponding accommodating groove, thereby detecting whether the infusion tube 30 is installed in place.

[0044] Further, an iron device can also be installed in the first accommodating groove, so that the first guide clamping part 21 and the second guide part can be more conveniently fixed in the corresponding first accommodating groove and second accommodating groove, thereby facilitating the installation operation of the user, the user only needs to place the first guide clamping part 21 and / or the second guide clamping part 22 near the first accommodating groove or the second accommodating groove, then the first guide clamping part 21 and the second guide clamping part 22 are automatically adsorbed and fixed in the corresponding first accommodating groove or second accommodating groove.

[0045] Further, the infusion pump further comprises a front door assembly 12, the front door assembly 12 is rotatably installed on the rack 11, when the infusion tube 30 is installed, the front door assembly covers the accommodating groove, the liquid stopping groove and the infusion groove; when the front door assembly 12 is opened, the user can install the infusion tube 30 and the liquid stopping device in the corresponding position, when the user installs it, the user only needs to cover the front door assembly 12 on the accommodating groove and the liquid stopping groove, so as to realize the positioning of the infusion tube 30 and the liquid stopping device, thereby facilitating the user to install and fix the infusion tube 30 and the liquid stopping device.

[0046] In the embodiment, the infusion pump further comprises a pre-pressing block 13, the pre-pressing block 13 is installed on the side of the front door assembly 12 facing the infusion groove, when the front door assembly 12 is covered, the pre-pressing block 13 abuts against the liquid stopping device, so as to fix the liquid stopping device in the liquid stopping groove; by arranging the pre-pressing block 13, the running failure of the liquid stopping device is reduced.

[0047] Referring to Figures 4 to 8 In the embodiment, the liquid stopping device comprises a driving assembly and a liquid stopping clamp 42, which are installed on the rack 11, the driving assembly is in transmission connection with the liquid stopping clamp 42, so as to make the liquid stopping clamp 42 open or close the infusion tube 30.

[0048] Specifically, the driving assembly is mounted to the rack 11, the liquid-stopping clamp 42 comprises a fixed plate 422 and a first elastic plate 421 arranged oppositely, the first elastic plate 421 is connected to one end of the fixed plate 422, the fixed plate 422 is mounted to the rack 11, and the first elastic plate 421 is in transmission connection with the driving assembly, so that the liquid-stopping device has a liquid-stopping state and a liquid-delivering state. In the liquid-stopping state, the driving assembly pushes the first elastic plate 421 to move towards the fixed plate 422, so as to clamp the infusion tube 30. In the liquid-delivering state, the driving assembly disappears the acting force on the first elastic plate 421, and the first elastic plate 421 moves away from the fixed plate 422, so as to release the infusion tube 30. Therefore, the state switching of the liquid-stopping device does not need to be controlled manually, which facilitates the user to operate the liquid-stopping device, and improves the work efficiency and experience of the user.

[0049] In the embodiment, the fixed plate 422 or the first elastic plate 421 is provided with a liquid-stopping portion. In the liquid-stopping state, the driving assembly pushes the first elastic plate 421 to move towards the fixed plate 422, so that the liquid-stopping portion clamps the infusion tube 30 together with the fixed plate 422 or the first elastic plate 421. The liquid-stopping portion is arranged, so that the driving assembly is more likely to deform the infusion tube 30 when pushing the first elastic plate 421, and the liquid-stopping effect is more easily achieved. Of course, in other embodiments, the liquid-stopping portion can also be arranged on the side of the fixed plate 422 facing the first elastic plate 421.

[0050] Specifically, the liquid-stopping portion is a liquid-stopping protrusion 4211, which has a simple structure and is easy to process and manufacture, thereby reducing the production cost of the liquid-stopping device.

[0051] Further, the liquid-stopping protrusion 4211 is arranged on the side of the first elastic plate 421 facing the fixed plate 422, and the cross-sectional area of the liquid-stopping protrusion 4211 gradually decreases towards the fixed plate 422, thereby reducing the contact area between the liquid-stopping protrusion 4211 and the infusion tube 30, and more easily achieving the liquid-stopping effect on the infusion tube 30 by the liquid-stopping protrusion 4211. Therefore, only a smaller driving force is needed to achieve the liquid-stopping effect on the infusion tube 30, thereby reducing the energy consumption of the driving motor 411.

[0052] In the embodiment, the liquid stopping clamp 42 further comprises a second elastic plate 423 connected to the fixed plate 422 at an end away from the first elastic plate 421, and the second elastic plate 423 is provided with a stop portion, in the liquid stopping state, the first elastic plate 421 is limited in the stop portion, in the infusion state, the driving assembly pushes the second elastic plate 423 to move away from the first elastic plate 421, so that the first elastic plate 421 is separated from the stop portion, and the first elastic plate 421 moves away from the fixed plate 422 to release the infusion tube 30; by the stop portion, when the liquid stopping clamp 42 is in the liquid stopping state, the stop portion can be further increased on the basis of the driving assembly to limit the first elastic plate 421, thereby increasing the stability of the liquid stopping clamp 42, and reducing the possibility of failure of the liquid stopping clamp 42 due to failure of the driving assembly.

[0053] Specifically, the stop portion is a stop protrusion 4231, when the liquid stopping device is in the liquid stopping state, the upper end of the first elastic plate 421 abuts against the side edge of the stop protrusion 4231, thereby avoiding the first elastic plate 421 moving away from the fixed plate 422, and further avoiding the driving force of the driving assembly being kept all the time to keep the liquid stopping device in the liquid stopping state, thereby reducing the energy consumption, and reducing the power consumption and use cost of the liquid stopping device; when the liquid stopping device needs to switch to the infusion state, the driving assembly drives the second elastic plate 423 to move away from the first elastic plate 421, so that the stop protrusion 4231 on the second elastic plate 423 is separated from the first elastic plate 421, and at the same time, the driving force of the driving assembly driving the first elastic plate 421 disappears, so that the first elastic plate 421 moves away from the fixed plate 422, thereby releasing the infusion tube 30, and further switching the liquid stopping device to the infusion state.

[0054] Of course, in other embodiments, the stop portion can also be a stop protrusion 4231, since the second elastic plate 423 is connected to the fixed plate 422 at an end away from the first elastic plate 421, the second elastic plate 423 has a tendency to move towards the first elastic plate 421, so that when the first elastic plate 421 moves to the stop groove, the second elastic plate 423 moves towards the first elastic plate 421, thereby making the first elastic plate 421 clamped in the stop groove.

[0055] Further, the second elastic plate 423 comprises a connecting section 4232 and a pushing section 4233, the connecting section 4232 is connected with the fixed plate 422 away from one end of the first elastic plate 421, the pushing section 4233 is connected with the connecting section 4232 away from one end of the fixed plate 422, the driving assembly is in transmission connection with the pushing section 4233, and the thickness of the pushing section 4233 is greater than that of the connecting section 4232, so as to form the stop protrusion 4231; of course, in other embodiments, the stop protrusion 4231 can also be a stop plate added on the side of the second elastic plate 423 facing the first elastic plate 421.

[0056] Specifically, the driving assembly comprises a driving motor 411 and a transmission member, the driving motor 411 is installed on the rack 11, and the transmission member is in transmission connection with the output shaft of the driving motor 411, so as to make the liquid stop clamp 42 open or close; the driving motor 411 has stable performance and low cost, thereby improving the production cost of the infusion pump and also improving the stability of the infusion pump; of course, in other embodiments, the driving assembly can also be a driving cylinder and a push rod, the output shaft of the cylinder is in transmission connection with the push rod, the push rod is in transmission connection with the first elastic plate 421, and the cylinder drives the first elastic plate 421 to move forward or backward, so as to switch the liquid stop device between the infusion state and the liquid stop state.

[0057] In the embodiment, the transmission member is a transmission wheel 412, the driving motor 411 is installed on the rack 11, the output shaft of the driving motor 411 is in transmission connection with the transmission wheel 412, the transmission wheel 412 is provided with a first swing arm 4121 and a second swing arm 4122, and the liquid stop device also has an initial state, in the liquid stop state, the driving motor 411 drives the first swing arm 4121 to push the first elastic plate 421 to move in the direction close to the fixed plate 422, and the second swing arm 4122 avoids the second elastic plate 423; in the infusion state, the driving motor 411 drives the second swing arm 4122 to push the second elastic plate 423 to move in the direction away from the first elastic plate 421, and the first swing arm 4121 avoids the first elastic plate 421; in the initial state, the first swing arm 4121 avoids the first elastic plate 421, and the second swing arm 4122 avoids the second elastic plate 423.

[0058] Further, the driving assembly further comprises a driving plate 413 and a blocking wheel 414, the driving plate 413 is installed on the frame 11, the light coupling of the driving plate 413 is signal connected with the driving motor 411, the blocking wheel 414 is installed on the transmission wheel 412, the outer circumferential surface of the blocking wheel 414 is provided with a first blocking tooth 4141, a second blocking tooth 4142 and a third blocking tooth 4143, in the liquid stopping state, the driving motor 411 drives the first blocking tooth 4141 to rotate to shield the light coupling; in the infusion state, the driving motor 411 drives the second blocking tooth 4142 to rotate to shield the light coupling; in the initial state, the driving motor 411 drives the third blocking tooth 4143 to rotate to shield the light coupling.

[0059] It should be noted that the light coupling of the driving motor 411 is signal connected with the driving motor 411, when the corresponding blocking tooth of the blocking wheel 414 shields the light coupling, at this time the signal connection between the light coupling and the driving motor 411 is interrupted, thereby equivalent to giving the driving motor 411 a stop signal, and then the driving motor 411 stops running, and then the transmission wheel 412 stops at the corresponding position; the other part of the electronic elements of the driving plate 413 controls the re-start and operation of the driving motor 411.

[0060] Further, the two sides of the fixing plate 422 are provided with a mounting plate 424, the mounting plate 424 is provided with a limiting hole 4241, the infusion tube 30 passes through the limiting hole 4241 to be limited on the mounting plate 424, through the limiting holes 4241 on the two sides of the fixing plate 422, so that the infusion tubes 30 on the two sides of the liquid stopping device are all limited, thereby reducing the possibility that the liquid stopping clamp 42 deviates too much in the liquid stopping process, and then the stability of the liquid stopping device is improved.
