[0002] Infusion stents are one of the most commonly used tools in medical devices.
[0003] Existing infusion stents cannot guarantee the stability of the entire device during operation while achieving convenient mobility, which affects the patient's infusion. Based on this, we propose a mobile infusion stent to solve the above-mentioned technical problems. Summary of the Invention
[0004] The purpose of this invention is to provide a mobile infusion stent to solve the problems mentioned in the background art.

The bottom wall of the hollow base has an clearance groove. The support assembly includes a polygonal U-shaped guide sleeve fixedly mounted on the hollow base, a T-shaped support rod cooperating with the polygonal U-shaped guide sleeve, a lifting component embedded in the support rod, a pressure sensor fixedly mounted on the inner bottom wall of the polygonal U-shaped guide sleeve, and an annular counterweight. The inner side wall of the polygonal U-shaped guide sleeve has symmetrically formed guide grooves. The T-shaped end of the T-shaped support rod is slidably mounted within the guide groove with damping. The outer side wall of the T-shaped support rod located outside the polygonal U-shaped guide sleeve has a second guide groove cooperating with the annular counterweight. The annular counterweight is slidably mounted within the second guide groove. Springs are connected between the support rod and the lower sidewall of the guide slide. A transition connecting plate is fixedly installed at the telescopic end of the lifting component. The infusion suspension assembly is set on the transition connecting plate. A positioning assembly is provided between the T-shaped support rod and the annular counterweight. The pressure sensor is electrically connected to the lifting moving assembly. When the annular counterweight is at the lower limit position of the second guide slide, the annular counterweight is in contact with the upper end face of the polygonal U-shaped guide sleeve, the spring is in its natural state, the T-shaped support rod is above the pressure sensor, and the lifting moving assembly is in a moving state. When the annular counterweight is at the upper limit position of the second guide slide, the weight of the annular counterweight is greater than the sum of the spring force and the damping force between the T-shaped support rod and the guide slide, and the T-shaped support rod presses against the pressure sensor. When the T-shaped support rod presses against the pressure sensor, the lifting moving assembly is in a non-moving state.
[0006] As a further aspect of the present invention, the lifting component is a drive cylinder.
[0007] As a further embodiment of the present invention: the outer wall of the annular counterweight is symmetrically provided with positioning holes, the positioning assembly includes symmetrically arranged positioning units, the positioning unit includes a positioning sleeve fixedly installed on a T-shaped support rod, a guide plate is slidably installed inside the positioning sleeve, a return spring is connected between one side of the guide plate and the inner wall of the positioning sleeve, an L-shaped support rod is fixedly installed on the other side of the guide plate, and a positioning rod that cooperates with the positioning hole is fixedly installed at the end of the L-shaped support rod.

Guide shafts are symmetrically arranged on both sides of the driving cylinder. The guide shafts are fixedly installed on the hollow base. A support positioning plate is fixedly installed on the telescopic end of the driving cylinder. The support positioning plate is slidably installed on the guide shaft. The moving rollers are evenly distributed at the bottom of the support positioning plate. The pressure sensor is electrically connected to the driving cylinder. When the pressure sensor is in the holding state, the driving cylinder is in the shortest stroke position. When the driving cylinder is in the shortest stroke position, the lowest surface of the moving rollers is higher than the lower surface of the hollow base.
[0010] As a further embodiment of the present invention: the top inner wall of the hollow base is symmetrically provided with limiting grooves, the lifting moving component includes a moving motor fixedly installed on the outer wall of the hollow base and several second moving rollers evenly distributed at the bottom of the hollow base, the output end of the moving motor is fixedly installed with a bidirectional rotating screw, the bidirectional rotating screw is rotatably installed on the hollow base, the bidirectional rotating screw is symmetrically provided with guide blocks, the guide blocks are all slidably installed in the limiting grooves, the bottom of the guide blocks is fixedly installed with an L-shaped mounting plate passing through the avoidance groove, the L-shaped mounting plate is fixedly installed with several arc-shaped brake plates corresponding to the second moving rollers, the arc-shaped brake plates are all provided with arc-shaped brake pads, the pressure sensor is electrically connected to the moving motor, when the pressure sensor is in the pressing state, the arc-shaped brake pads are away from the second moving rollers.
[0011] As a further improvement of the present invention, anti-slip sleeves are provided on all the infusion suspension hooks.
[0012] Compared with the prior art, the beneficial effects of the present invention are: By setting up an annular counterweight and a pressure sensor, and since the pressure sensor is electrically connected to the lifting and moving assembly, when the annular counterweight is at its lower limit position in the second guide groove, the annular counterweight is in contact with the upper surface of the polygonal U-shaped guide sleeve, the spring is in its natural state, the T-shaped support rod is above the pressure sensor, and the lifting and moving assembly is in a moving state. When the annular counterweight is at its upper limit position in the second guide groove, the weight of the annular counterweight is greater than the sum of the spring force and the damping force between the T-shaped support rod and the guide groove, and the T-shaped support rod presses against the pressure sensor. When the T-shaped support rod presses against the pressure sensor, the lifting and moving assembly is in a non-moving state. This achieves the overall stability of the device while also enabling convenient movement of the device when it is idle. Attached Figure Description

Detailed Implementation
[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments. Example 1
[0019] Please see Figure 1-4A mobile infusion stand includes a hollow base 1, a lifting and moving assembly disposed within the hollow base 1, a support assembly fixedly mounted on the hollow base 1, and an infusion suspension assembly disposed at the upper end of the support assembly. The bottom wall of the hollow base 1 has an clearance groove. The support assembly includes a polygonal U-shaped guide sleeve 2 fixedly mounted on the hollow base 1, a T-shaped support rod 4 cooperating with the polygonal U-shaped guide sleeve 2, a lifting component 5 embedded in the support rod 4, a pressure sensor 3 fixedly mounted on the bottom inner wall of the polygonal U-shaped guide sleeve 2, and an annular counterweight 6. The inner side wall of the polygonal U-shaped guide sleeve 2 has symmetrically formed guide grooves 7. The T-shaped end of the T-shaped support rod 4 is slidably mounted in the guide grooves 7 with damping. The outer side wall of the T-shaped support rod 4, located outside the polygonal U-shaped guide sleeve 2, has a second guide groove 8 cooperating with the annular counterweight 6. The annular counterweight 6 is slidably mounted in the second guide groove 8. Springs 9 are connected between rod 4 and the lower sidewall of guide groove 7. Transition connecting plate 10 is fixedly installed at the telescopic end of lifting component 5. Infusion suspension assembly is set on transition connecting plate 10. Positioning assembly is set between T-shaped support rod 4 and annular counterweight 6. Pressure sensor 3 is electrically connected to lifting moving assembly. When annular counterweight 6 is at the lower limit position of second guide groove 8, annular counterweight 6 is in contact with the upper end face of polygonal U-shaped guide sleeve 2, spring 9 is in natural state, T-shaped support rod 4 is above pressure sensor 3, and lifting moving assembly is in moving state. When annular counterweight 6 is at the upper limit position of second guide groove 8, the weight of annular counterweight 6 is greater than the sum of spring force 9 and damping force between T-shaped support rod 4 and guide groove 7, and T-shaped support rod 4 is pressed on pressure sensor 3. When T-shaped support rod 4 is pressed on pressure sensor 3, lifting moving assembly is in non-moving state.
[0020] By setting up an annular counterweight 6 and a pressure sensor 3, and since the pressure sensor 3 is electrically connected to the lifting and moving assembly, when the annular counterweight 6 is at the lower limit position of the second guide groove 8, the annular counterweight 6 is in contact with the upper end face of the polygonal U-shaped guide sleeve 2, the spring 9 is in its natural state, the T-shaped support rod 4 is above the pressure sensor 3, and the lifting and moving assembly is in a moving state; when the annular counterweight 6 is at the upper limit position of the second guide groove 8, the weight of the annular counterweight 6 is greater than the sum of the elastic force of the spring 9 and the damping force between the T-shaped support rod 4 and the guide groove 7, and the T-shaped support rod 4 presses against the pressure sensor 3; when the T-shaped support rod 4 presses against the pressure sensor 3, the lifting and moving assembly is in a non-moving state; thus, the overall device achieves operational stability while also enabling convenient movement of the overall device when idle.
[0021] The lifting component 5 is a drive cylinder.
[0022] The outer wall of the annular counterweight 6 is symmetrically provided with positioning holes 11. The positioning assembly includes symmetrically arranged positioning units. The positioning unit includes a positioning sleeve 12 fixedly installed on the T-shaped support rod 4. A guide plate 13 is slidably installed inside the positioning sleeve 12. A return spring 14 is connected between one side of the guide plate 13 and the inner wall of the positioning sleeve 12. An L-shaped support rod 15 is fixedly installed on the other side of the guide plate 13. A positioning rod 16 that cooperates with the positioning hole 11 is fixedly installed at the end of the L-shaped support rod 15. This achieves the stability of the annular counterweight 6 on the T-shaped support rod 4.
[0023] The infusion suspension assembly includes an infusion suspension rod 17 fixedly installed on the transition connecting plate 10 and several infusion suspension hooks 18 evenly distributed on the infusion suspension rod 17.

Guide shafts 21 are symmetrically arranged on both sides of the drive cylinder 19, and the guide shafts 21 are fixedly installed on the hollow base 1. A support positioning plate 22 is fixedly installed on the telescopic end of the drive cylinder 19, and the support positioning plate 22 is slidably installed on the guide shafts 21. The moving rollers 20 are evenly distributed at the bottom of the support positioning plate 22. The pressure sensor 3 is electrically connected to the drive cylinder 19. When the pressure sensor 3 is in a pressing state, the drive cylinder 19... When cylinder 19 is in its shortest stroke position, the lowest surface of the moving roller 20 is higher than the lower surface of the hollow base 1. By setting the driving cylinder 19, when the whole device is in a stationary working state, the driving cylinder 19 is in its shortest stroke position, and the hollow base 1 serves as the support for the whole device. When the whole device needs to be moved, the driving cylinder 19 drives the moving roller 20 to touch the ground through the support positioning plate 22, thereby realizing the convenient movement of the whole device, while ensuring the placement stability of the whole device when it is in a stationary working state.
[0025] In another embodiment, the top inner wall of the hollow base 1 is symmetrically provided with limiting grooves. The lifting and moving assembly includes a moving motor 23 fixedly installed on the outer wall of the hollow base 1 and several second moving rollers 24 evenly distributed at the bottom of the hollow base 1. The output end of the moving motor 23 is fixedly installed with a bidirectional rotating screw 25. The bidirectional rotating screw 25 is rotatably installed on the hollow base 1. Guide blocks 26 are symmetrically arranged on the bidirectional rotating screw 25. The guide blocks 26 are all slidably installed in the limiting grooves. The bottom of the guide blocks 26 is... An L-shaped mounting plate 27 is fixedly installed through the clearance groove. Several arc-shaped brake plates 28 corresponding to the second moving rollers 24 are fixedly installed on the L-shaped mounting plate 27. Each arc-shaped brake plate 28 is provided with an arc-shaped brake pad 29. The pressure sensor 3 is electrically connected to the moving motor 23. When the pressure sensor 3 is in the pressing state, the arc-shaped brake pad 29 moves away from the second moving rollers 24. By setting the second moving rollers 24, the moving motor 23, and the arc-shaped brake pads 29, the overall device can be easily moved while maintaining stability when stationary.
[0026] The working principle of this embodiment is as follows: By setting an annular counterweight 6 and a pressure sensor 3, since the pressure sensor 3 is electrically connected to the lifting and moving assembly, when the annular counterweight 6 is at the lower limit position of the second guide groove 8, the annular counterweight 6 is in contact with the upper end face of the polygonal U-shaped guide sleeve 2, the spring 9 is in its natural state, the T-shaped support rod 4 is above the pressure sensor 3, and the lifting and moving assembly is in a moving state; when the annular counterweight 6 is at the upper limit position of the second guide groove 8, the weight of the annular counterweight 6 is greater than the sum of the elastic force of the spring 9 and the damping force between the T-shaped support rod 4 and the guide groove 7, and the T-shaped support rod 4 presses against the pressure sensor 3; when the T-shaped support rod 4 presses against the pressure sensor 3, the lifting and moving assembly is in a non-moving state; thereby achieving the working stability of the overall device and realizing convenient movement of the overall device when idle.
