The card pins pass through the docking frame and are inserted into the card interfaces, and elastic support members are provided between the two card pins and the surface of the docking frame.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. When the pressure detection component approaches the infusion tube, the linkage component links the two straightening claws to move back to each other, and the two straightening claws move from the top of the infusion tube in the shelf groove to contact and smooth the infusion tube. During the movement of the two straightening claws, a limited space is always formed between the arc-shaped smoothing groove and the shelf groove to maintain the covering of the infusion tube. Then, during the movement of the straightening claws, the infusion tube is smoothed toward both ends of the shelf groove, so that the infusion tube fits into the shelf groove. With the limited support of the shelf groove, it is conducive to straightening the infusion tube in the shelf groove, providing a stable state for the pressure detection of the pressure detection component, and is conducive to the accuracy of the pressure detection component in detecting the pressure of the infusion tube.

[0018] 2. In the process of lowering the height of the first movable plate, the linkage plate moves synchronously, and the linkage plate drives the linkage pin to move in the inclined groove, thereby pushing the movable frame to move. Since the two inclined grooves are symmetrically arranged, the two movable frames move back to back with each other synchronously, and the two movable frames drive the two straightening claws to move away from each other synchronously, thereby providing power to the two straightening claws in the process of driving the pressure detection component to apply pressure to the infusion tube, so that the infusion tube is automatically smoothed and straightened in the shelf groove.

[0019] 3. After the straightening claw has straightened the infusion tube, the arc plate is moved in the arc installation cavity. When the arc plate moves, it will drive the linkage groove to move on the surface of the guide pin. During the movement of the second arc groove on the surface of the guide pin, the guide pin remains stationary. During the process of the first guide inclined groove passing the guide pin, the guide pin will be pushed. The guide pin drives the adjustment rod to move, and the adjustment rod pushes the rubber damping plate. The rubber damping plate will be pushed by the adjustment rods in multiple positions, so that the rubber damping plate is attached to the surface of the straightened infusion tube. Until the third arc groove moves to the surface of the guide pin, the adjustment is completed, so that the positions of the infusion tube at both ends of the shelf groove are damped and limited, which is conducive to maintaining the stability of the infusion tube in the shelf groove and providing favorable detection conditions for the pressure detection component.

[0020] 4. By arranging rubber damping sheets on both sides of the arc-shaped smoothing body, the infusion tube is subjected to enhanced damping when moving on both sides of the arc-shaped smoothing body, which helps prevent the infusion tube from moving in the extension direction of the shelf groove.

[0021] 5. Through the docking between the arc plate and the limiting groove, the straightening claw is limited to the position of the infusion tube after straightening, thereby indirectly supporting the damping component and maintaining the stability of the relative position of the damping component and the shelf groove. The arc plate not only provides support for the pressing of the rubber damping sheet, but also realizes the positioning of the straightening claw relative to the shelf groove.

DETAILED DESCRIPTION

[0024] like Figures 1 to 10 As shown, in one embodiment, a pressure testing device for an electronic analgesia pump infusion system includes a mounting plate 1 and further includes: A first movable plate 2 is slidably connected to the mounting plate 1 and a pressure detection assembly is mounted on the first movable plate 2; The second movable plate 3 is slidably connected to the mounting plate 1. A shelf groove 4 is provided on the top of the second movable plate 3. A liquid infusion tube 5 is placed in the shelf groove 4. A straightening assembly includes two straightening claws 6, which are located on both sides of the infusion tube 5 at the position to be detected. The straightening claws 6 have an arc-shaped smoothing groove 7; The linkage component is used to link the two straightening claws 6 to move back to each other when the first movable plate 2 drives the pressure detection component close to the infusion tube 5. The two straightening claws 6 move from the top of the infusion tube 5 in the shelf groove 4 to contact and smooth the infusion tube 5.

[0025] Specifically, a slide groove 8 is provided on the front of the mounting plate 1, and the backs of the first movable plate 2 and the second movable plate 3 are both slidably connected in the slide groove 8; A first threaded drive assembly and a second threaded drive assembly are respectively provided between the first movable plate 2 and the second movable plate 3 and the mounting plate 1, and the first threaded drive assembly includes a first motor 9, the first motor 9 is fixedly mounted on the top end of the front face of the mounting plate 1, and the output end is fixedly connected to a first threaded rod 10, the first movable plate 2 is threadedly connected to the surface of the first threaded rod 10, and the first motor 9 drives the first threaded rod 10 to rotate, and the first threaded rod 10 threadably drives the first movable plate 2 to achieve height adjustment of the first movable plate 2, and the second threaded drive assembly includes a second motor 11, the second motor 11 is fixedly connected to the bottom end of the front face of the mounting plate 1, and the output end of the second motor 11 is fixedly connected to the second threaded rod 12, and the second movable plate 3 is threadedly connected to the surface of the second threaded rod 12. By starting the second motor 11, the second motor 11 drives the second threaded rod 12 to rotate, and the second threaded rod 12 threadably drives the second movable plate 3 to move, so as to achieve height adjustment of the second movable plate 3; It should be understood that in the process of connecting the infusion tube 5 to the to-be-tested station of the pressure detection assembly, the infusion tube 5 is placed in the shelf groove 4 of the first movable plate 2. Then, the second movable plate 3 is threadedly driven by the second threaded drive assembly to move to a preset height, and the infusion tube 5 is supported in the shelf groove 4 to achieve positional support for the infusion tube 5. The inner wall of the shelf groove 4 is arc-shaped to accommodate the tubular shape of the infusion tube 5. During the process of supporting and moving the infusion tube 5 by the resting groove 4, the second movable plate 3 will gradually approach the straightening claw 6 until the arc-shaped smoothing groove 7 at the bottom of the straightening claw 6 is extended to the surface of the infusion tube 5, and a limiting space is formed between the arc-shaped smoothing groove 7 and the resting groove 4, covering and limiting the infusion tube 5; Before the infusion tube 5 is limited, a distance is maintained between the first movable plate 2 and the second movable plate 3 so that there is space between the pressure detection component and the shelf groove 4 to provide space for the passage of the infusion tube 5; After the support and limit of the infusion tube 5 is completed, the first movable plate 2 is driven to descend by the first thread driving component threadedly driving the first movable plate 2 to move downward, and the first movable plate 2 drives the pressure detection component to move synchronously. In the process of the pressure detection component approaching the infusion tube 5, the linkage component links the two straightening claws 6 to move back to each other, and the two straightening claws 6 move from the top of the infusion tube 5 in the shelf groove 4 to contact and move, and the infusion tube 5 is smoothed. In the process of the movement of the two straightening claws 6, a limiting space is always formed between the arc-shaped smoothing groove 7 and the shelf groove 4 to maintain the covering of the infusion tube 5, and then in the process of the straightening claws 6 moving, the infusion tube 5 is smoothed toward the two ends of the shelf groove 4, so that the infusion tube 5 is fitted into the shelf groove 4. Under the limited support of the shelf groove 4, it is conducive to straightening the infusion tube 5 in the shelf groove 4, providing a stable state for the pressure detection of the pressure detection component, which is conducive to the accuracy of the pressure detection of the infusion tube 5 by the pressure detection component; The liquid in the infusion tube 5 is conveyed, but when the position where the end of the infusion tube 5 connects to the human body is blocked, the liquid in the infusion tube 5 will expand the infusion tube 5, and the pressure detection component will detect the pressure change in time, providing the staff with information based on which to judge possible blockage.

[0026] like Figure 1 and Figure 5 As shown, in one embodiment, the pressure detection assembly includes a mounting seat 13 and two support rods 14, the two support rods 14 are inserted into the bottom end of the first movable plate 2, the bottoms of the two support rods 14 are fixedly connected to a pressure plate 15, the top ends of the two support rods 14 pass through the first movable plate 2 and are fixedly connected to a top plate 16, the top of the top plate 16 is fixedly connected to an elastic telescopic rod 1601, the mounting seat 13 is fixedly connected to the top of the mounting plate 1, and 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.

[0027] It should be understood that the first movable plate 2 synchronously drives the mounting seat 13, the support rod 14 and the pressure plate 15 to approach the infusion tube 5 until the pressure plate 15 squeezes the infusion tube 5. The pressure plate 15 acts on the top plate 16 through the support rod 14. The elastic telescopic rod 1601 on the top plate 16 will squeeze the detection end of the pressure sensor 17. The pressure sensor 17 will detect the pressure. When the liquid in the infusion tube 5 exerts pressure on the infusion tube 5, the infusion tube 5 will press the pressure plate 15, and then transmit the pressure to the pressure sensor 17, so as to perform pressure detection on the infusion tube 5 in time.

[0028] like Figure 5 As shown, in one embodiment, a first arcuate groove 18 is formed on the bottom of the pressure plate 15. It should be understood that when the first arcuate groove 18 contacts the infusion tube 5, it can disperse the pressure and reduce local pressure concentration. Compared with pure flat pressing, it can better fit the outer contour of the hose and reduce the risk of damage.

[0029] like Figure 1 、 Figure 3 、 Figure 4 and Figure 7 As shown, in one embodiment, the straightening assembly further includes two mobile frames 19, the back surfaces of the two mobile frames 19 are in contact with the mounting plate 1, the two mobile frames 19 are respectively fixedly connected to the ends of the two straightening claws 6, and the surfaces of the two mobile frames 19 are fixedly connected to first support sleeves 20, and the two first support sleeves 20 are slidably plugged with positioning rods 21, and the two positioning rods 21 are respectively fixedly connected to the two sides of the mounting plate 1, and the linkage assembly is arranged between the two mobile frames 19 and the first movable plate 2. It should be understood that the support for the mobile frames 19 is achieved through the cooperation of the positioning rods 21 and the first support sleeves 20, and the mobile frames 19 support the straightening claws 6, so that the height of the straightening claws 6 remains unchanged, but can move laterally.

[0030] like Figure 1 、 Figure 3 and Figure 5 As shown, in one embodiment, the linkage assembly includes two symmetrically arranged inclined slots 22, the two inclined slots 22 being respectively opened on the surfaces of the two movable frames 19, and a linkage pin 23 being slidably arranged in each of the two inclined slots 22. The ends of the two linkage pins 23 are rotatably connected to a linkage plate 24, and the top ends of the two linkage plates 24 are fixedly connected to the bottom of the first movable plate 2. It should be understood that during the process of lowering the height of the first movable plate 2, the linkage plate 24 moves synchronously, and the linkage plate 24 drives the linkage pin 23 to move in the inclined slots 22, thereby pushing the movable frame 19 to move. Since the two inclined slots 22 are symmetrically arranged, the two movable frames 19 move synchronously away from each other, and the two movable frames 19 synchronously drive the two straightening claws 6 to move away from each other, thereby providing power to the two straightening claws 6 in the process of driving the pressure detection assembly to apply pressure to the infusion tube 5, so that the infusion tube 5 is automatically straightened in the shelf 4.

[0031] like Figure 7 As shown, in one embodiment, a curved smoothing body 25 is fixedly mounted within the curved smoothing groove 7. The curved smoothing body 25 has a smooth surface. The curved smoothing body 25 adapts to the shape of the infusion tube 5 to retain the infusion tube 5 within the resting groove 4. As the straightening claw 6 moves, the curved smoothing body 25 moves along the upper surface of the infusion tube 5, smoothing the infusion tube 5. The smoothed infusion tube 5 is then straightened within the resting groove 4.

[0032] like Figure 3 、 Figure 4 and Figure 5 As shown, in one embodiment, damping components are provided on both sides of the arc-shaped smoothing body 25, and the damping components include two arc-shaped mounting cavities 26 and rubber damping sheets 27. The rubber damping sheets 27 are fixedly connected to the side walls of the arc-shaped smoothing body 25. The two arc-shaped mounting cavities 26 are opened on both sides of the straightening claw 6. An arc-shaped plate 28 is slidably provided in the arc-shaped mounting cavity 26. A plurality of linkage grooves 29 are opened on the surface of the arc-shaped plate 28. A guide pin 33 is slidably provided in the plurality of linkage grooves 29. The end of the guide pin 33 is fixedly connected to an adjusting rod 34. The plurality of adjusting rods 34 penetrate the straightening claw 6 and extend into the arc-shaped smoothing groove 7. The plurality of adjusting rods 34 are fixedly connected to the surface of the rubber damping sheet 27. The rubber damping sheets 27 of the two damping components are symmetrically arranged. The linkage groove 29 includes a second arcuate groove 2901 , a first guide inclined groove 2902 and a third arcuate groove 2903 , and the guide pin 33 is slidably disposed in the third arcuate groove 2903 .

[0033] 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 component, the infusion tube 5 is damped and limited. The specific method is as follows: When the second curved groove 2901 moves on the surface of the guide pin 33, the guide pin 33 remains stationary. When the first guide inclined groove 2902 passes the guide pin 33, the guide pin 33 is pushed. The guide pin 33 drives the adjustment rod 34 to move. The adjustment rod 34 pushes the rubber damping sheet 27. The rubber damping sheet 27 is pushed by the adjustment rod 34 at multiple positions, so that the rubber damping sheet 27 is attached to the surface of the straightened infusion tube 5. When the third curved groove 2903 moves to the surface of the guide pin 33, the adjustment is completed, so that the positions of the infusion tube 5 at both ends of the shelf groove 4 are damped and limited, which is conducive to keeping the infusion tube 5 in the shelf groove 4 stable and providing favorable detection conditions for the pressure detection component. By arranging rubber damping sheets 27 on both sides of the arc-shaped smoothing body 25, the infusion tube 5 is subjected to enhanced damping when moving on both sides of the arc-shaped smoothing body 25, which helps prevent the infusion tube 5 from moving in the shelf groove 4 along the extension direction of the shelf groove 4.

[0034] like Figure 1 、 Figure 3 、 Figure 4 and Figure 6 As shown, in one embodiment, two limiting grooves 35 are defined on the top of the second movable plate 3. The curved plates 28 on the two damping assemblies are respectively slidably inserted into the two limiting grooves 35. A toggle rod 36 is fixedly connected between the two curved plates 28 of the same damping assembly. It should be understood that the docking between the curved plates 28 and the limiting grooves 35 allows the straightening claw 6 to limit the position of the infusion tube 5 after straightening, thereby indirectly supporting the damping assembly and maintaining the stability of the relative position of the damping assembly and the shelf 4. The curved plates 28 not only provide support for the pressing of the rubber damping sheet 27, but also position the straightening claw 6 relative to the shelf 4.

[0035] like Figure 2 、 Figure 9 and Figure 10As shown, in one embodiment, a mounting frame 37 is fixedly connected to the back of the mounting plate 1. Card interfaces 38 are provided on both sides of the mounting frame 37. A docking frame 39 is sleeved on the surface of the mounting frame 37. Positioning holes 40 are provided on the edges of the docking frame 39. Card pins 32 are inserted on both sides of the docking frame 39. The card pins 32 pass through the docking frame 39 and are inserted into the card interfaces 38. Elastic support members are provided between the two card pins 32 and the surface of the docking frame 39. It should be understood that before installing the pressure detection component in the electronic analgesia pump, the docking frame 39 is positioned by screws passing through the positioning holes 40 and then threadedly connected to the inner wall of the electronic analgesia pump. Then, the mounting frame 37 on the mounting plate 1 is inserted into the docking frame 39, and the card pins 32 are inserted into the card interfaces 38 to position and install the mounting plate 1, thereby achieving installation of the pressure detection component. The elastic support member includes a connecting pin 30, which is fixedly connected to the surface of the docking frame 39. A second support sleeve 41 is sleeved on the surface of the connecting pin 30. The second support sleeve 41 is fixedly connected to the surface of the snap-on pin 32. A support spring 31 is sleeved on the surface of the connecting pin 30. The two ends of the support spring 31 are respectively fixedly connected to the second support sleeve 41 and the docking frame 39. When the pressure detection assembly needs to be disassembled for maintenance, just pull the snap-on pin 32.
