[0041] The straightening assembly comprises two straightening claws 6, which are located on both sides of the to-be-detected position of the infusion tube 5, and the straightening claw 6 has an arc-shaped smoothing groove 7;

[0042] The linkage assembly is used for moving the two straightening claws 6 away from each other in the process that the first moving plate 2 drives the pressure detection assembly to approach the infusion tube 5, and the two straightening claws 6 contact and move from the top end of the infusion tube 5 in the resting groove 4 to flatten the infusion tube 5.

[0043] Specifically, the front surface of the mounting plate 1 is provided with a sliding groove 8, and the back surfaces of the first moving plate 2 and the second moving plate 3 are both slidingly connected in the sliding groove 8.

[0044] The first moving plate 2 and the second moving plate 3 are respectively provided with a first threaded driving assembly and a second threaded driving assembly between the first moving plate 2 and the second moving plate 3 and the mounting plate 1. The first threaded driving assembly comprises a first motor 9 fixedly installed at the top end of the front surface of the mounting plate 1, and the output end of the first motor 9 is fixedly connected with a first threaded rod 10, and the first moving plate 2 is threadedly connected on the surface of the first threaded rod 10.

The output end of the second motor 11 is fixedly connected with a second threaded rod 12, and the second moving plate 3 is threadedly connected on the surface of the second threaded rod 12. The second motor 11 is started to drive the second threaded rod 12 to rotate, the second threaded rod 12 threadedly drives the second moving plate 3 to move, and the height of the second moving plate 3 is adjusted.

[0045] It should be understood that, in the process of connecting the infusion tube 5 to the to-be-detected work position of the pressure detection assembly, the infusion tube 5 is arranged in the resting groove 4 of the first moving plate 2, then the second moving plate 3 is threadedly driven by the second threaded driving assembly to move to a preset height, the infusion tube 5 is supported in the resting groove 4, the infusion tube 5 is limited and supported, the inner wall of the resting groove 4 is arc-shaped to adapt to the tubular shape of the infusion tube 5.

[0046] In the process that the resting groove 4 supports and moves the infusion tube 5, the second moving plate 3 gradually approaches the straightening claw 6 until the arc-shaped flattening groove 7 at the bottom of the straightening claw 6 is arranged on the surface of the infusion tube 5, and a limiting space is formed between the arc-shaped flattening groove 7 and the resting groove 4 to limit and cover the infusion tube 5.

[0047] Before limiting the infusion tube 5, the first moving plate 2 and the second moving plate 3 keep a distance therebetween, so that a space is left between the pressure detection assembly and the resting groove 4 to provide space for the passing of the infusion tube 5.

[0048] After the support and limiting of the infusion tube 5 is completed, the first moving plate 2 is driven downward in height through the first threaded driving assembly, and the pressure detection assembly is synchronously moved by the first moving plate 2. In the process that the pressure detection assembly approaches the infusion tube 5, the linkage assembly moves the two straightening claws 6 away from each other, and the two straightening claws 6 move from the top end of the infusion tube 5 in the resting groove 4 to contact and move, so as to flatten the infusion tube 5. In the process that the two straightening claws 6 move, the limiting space is always formed between the arc-shaped flattening groove 7 and the resting groove 4, the infusion tube 5 is kept covered, and in the process that the two straightening claws 6 move, the infusion tube 5 is flattened towards both ends of the resting groove 4, so that the infusion tube 5 is attached to the resting groove 4. Under the limiting support of the resting groove 4, the infusion tube 5 is straightened in the resting groove 4, a stable state is provided for pressure detection of the pressure detection assembly, and the accuracy of pressure detection of the pressure detection assembly on the infusion tube 5 is improved.

[0049] When the end of the infusion tube 5 is blocked in communication with the human body, the liquid in the infusion tube 5 will expand the infusion tube 5, the pressure detection assembly can timely detect the change of the pressure, and the staff can be provided with basis information for judging the possible blockage.

[0050] As shown in Figure 1 and Figure 5 , in an embodiment, the pressure detection assembly comprises a mounting seat 13 and two support rods 14, the two support rods 14 are inserted into the bottom end of the first moving plate 2, the bottom of each support rod 14 is fixedly connected with a pressing plate 15, the top end of each support rod 14 penetrates through the first moving plate 2 and is fixedly connected with a top plate 16, the top of the top plate 16 is fixedly connected with an elastic telescopic rod 1601, the mounting seat 13 is fixedly connected to the top of the mounting plate 1, a pressure sensor 17 is fixedly installed on the mounting seat 13, and the detection end of the pressure sensor 17 is in contact with the top end of the elastic telescopic rod 1601.

[0051] It should be understood that the first moving plate 2 synchronously drives the mounting seat 13, the support rod 14 and the pressing plate 15 to approach the infusion tube 5, until the pressing plate 15 extrudes the infusion tube 5, the pressing plate 15 acts on the top plate 16 through the support rod 14, the elastic telescopic rod 1601 on the top plate 16 extrudes the detection end of the pressure sensor 17, the pressure sensor 17 detects the pressure, when the liquid in the infusion tube 5 presses the infusion tube 5, the infusion tube 5 presses the pressing plate 15, and then the pressure is transmitted to the pressure sensor 17, so as to timely detect the pressure of the infusion tube 5.

[0052] As shown in Figure 5 , in an embodiment, the bottom of the pressing plate 15 is provided with a first arc-shaped groove 18. It should be understood that when the first arc-shaped groove 18 is in contact with the infusion tube 5, the pressure can be dispersed, the local pressure concentration is reduced, the pure plane pressing is more attached to the outer contour of the hose, and the risk of damage is reduced.

[0053] As Figure 1 , Figure 3 , Figure 4 and Figure 7 shown, in one embodiment, the straightening assembly also includes two moving frames 19, the back of the two moving frames 19 is in contact with the mounting plate 1, the two moving frames 19 are fixedly connected at the end of the two straightening claws 6 respectively, the surface of the two moving frames 19 is fixedly connected with the first support sleeve 20, the two first support sleeves 20 are slidingly inserted with the positioning rod 21 respectively, the two positioning rods 21 are fixedly connected on both sides of the mounting plate 1, and the linkage assembly is arranged between the two moving frames 19 and the first moving plate 2. It should be understood that through the cooperation of the positioning rod 21 and the first support sleeve 20, the support of the moving frame 19 is realized, the moving frame 19 supports the straightening claw 6, so that the height of the straightening claw 6 remains unchanged, but can move horizontally.

It should be understood that in the process of lowering the height of the first moving plate 2, the linkage plate 24 moves synchronously, the linkage plate 24 drives the linkage pin 23 to move in the inclined groove 22, and then pushes the moving frame 19 to move. Since the two inclined grooves 22 are symmetrically arranged, the two moving frames 19 move synchronously and away from each other, and the two moving frames 19 drive the two straightening claws 6 to move away from each other, so as to provide power to the two straightening claws 6 during the process of driving the pressure detection assembly to press the infusion tube 5, so that the infusion tube 5 in the resting groove 4 is automatically flattened and straightened.

[0055] As Figure 7 shown, in one embodiment, the arc-shaped flattening body 25 is fixedly installed inside the arc-shaped flattening groove 7, and the surface of the arc-shaped flattening body 25 is smooth. By arranging the arc-shaped flattening body 25, the shape of the tube body of the infusion tube 5 can be adapted to limit the infusion tube 5 in the resting groove 4. During the movement of the straightening claw 6, the arc-shaped flattening body 25 will move along the upper surface of the infusion tube 5 to flatten the infusion tube 5, and the flattened infusion tube 5 will be straightened under the limitation of the resting groove 4.

[0056] As Figure 3 , Figure 4 and Figure 5As shown, in one embodiment, the two sides of the arc-shaped smoothing body 25 are provided with damping assemblies, which include two arc-shaped mounting cavities 26 and rubber damping pieces 27 fixedly connected to the side walls of the arc-shaped smoothing body 25, two arc-shaped mounting cavities 26 are arranged on the two sides of the straightening claw 6, an arc-shaped plate 28 is slidably arranged in the arc-shaped mounting cavity 26, a plurality of linkage grooves 29 are arranged on the surface of the arc-shaped plate 28, a guide pin 33 is slidably arranged in each linkage groove 29, an adjusting rod 34 is fixedly connected to the end of the guide pin 33, a plurality of adjusting rods 34 extend into the arc-shaped smoothing groove 7 through the straightening claw 6, and the plurality of adjusting rods 34 are fixedly connected to the surface of the rubber damping piece 27; the rubber damping pieces 27 of the two damping assemblies are symmetrically arranged.

[0057] The linkage groove 29 includes a second arc-shaped groove 2901, a first guide inclined groove 2902, and a third arc-shaped groove 2903, and the guide pin 33 is slidably arranged in the third arc-shaped groove 2903.

[0058] It should be understood that after the infusion tube 5 is straightened, in order to maintain the stability of the infusion tube 5 near the pressure detection assembly, the infusion tube 5 is damped and limited, and the specific method is as follows:

[0059] Firstly, after the straightening claw 6 has straightened the infusion tube 5, the arc-shaped plate 28 is moved in the arc-shaped mounting cavity 26, and the arc-shaped plate 28 moves while driving the linkage groove 29 to move on the surface of the guide pin 33; in the process of moving the second arc-shaped groove 2901 on the surface of the guide pin 33, the guide pin 33 remains stationary; in the process of the first guide inclined groove 2902 passing through the guide pin 33, the guide pin 33 is pushed, the guide pin 33 drives the adjusting rod 34 to move, the adjusting rod 34 pushes the rubber damping piece 27, the rubber damping piece 27 is pushed by a plurality of adjusting rods 34, so that the rubber damping piece 27 is attached to the surface of the straightened infusion tube 5, until the third arc-shaped groove 2903 moves to the surface of the guide pin 33, the adjustment is completed, so that the infusion tube 5 is damped and limited at the positions on both ends of the resting groove 4, which is beneficial to maintaining the stability of the infusion tube 5 in the resting groove 4 and providing favorable detection conditions for the pressure detection assembly;

It should be understood that the position of the straightening claw 6 after straightening the infusion tube 5 is limited by the butt joint between the arc-shaped plate 28 and the limiting groove 35, thereby indirectly supporting the damping assembly, maintaining the stability of the relative position of the damping assembly and the resting groove 4, and the arc-shaped plate 28 not only provides support by pressing the rubber damping piece 27, but also positions the straightening claw 6 relative to the resting groove 4.
