[0037] Reference Figure 6 , an infusion stand that is easy to adjust, the bottle hanging assembly 6 also includes a moving plate 22, the moving plate 22 is arranged at the inner side of the extension block 26, the moving plate 22 is slidably connected to the extension block 26, both ends of the extension block 26 are fixed with sliding blocks 24, the sliding block 24 is slidably connected to the extension block 26, the lower end of the moving plate 22 is fixed with a hook 23, the hook 23 extends to the outer side of the lower end of the extension block 26, the top of the moving plate 22 is fixed with a third spring 21, one end of the third spring 21 away from the moving plate 22 is fixedly connected to the top plate 4, and a sensor 25 is fixed at the inner top of the top plate 4 and at a position corresponding to the sliding block 24;

[0038] A controller 19 is fixed at the top of the top plate 4 and at a position corresponding to the moving plate 22, and the sensor 25 is electrically connected to the controller 19. An alarm light 20 is fixed at a side of the top plate 4 and at a position corresponding to the moving plate 22, and the alarm light 20 is electrically connected to the controller 19.

[0039] The device provided in this embodiment can promptly sound an alarm when there is no medicine in the drip bottle, thereby conveniently reminding the patient or medical staff to replace the drip bottle, reducing the occurrence of blood backflow in the patient and improving the practicality of the device.

[0040] The utility model provides an easy-to-adjust infusion stand. The use process of the infusion stand is as follows: when the height of the top plate 4 needs to be adjusted, first pull the rotating handle 9 in the direction away from the fixed column 1, so that the rotating handle 9 drives the connecting block 15 to move through the connecting rod 12. When the connecting block 15 moves, it will squeeze the plug-in block 14, so that the plug-in block 14 moves in the direction close to the second spring 18. When the connecting block 15 moves to the position where the plug-in block 14 corresponds to the plug-in slot, the plug-in block 14 moves to the inner side of the plug-in slot under the elastic action of the second spring 18, so that the plug-in block 14 is plug-connected with the fixed block 11 through the plug-in slot, and then the rotating handle 9 is rotated so that the rotating handle 9 drives the connecting block 15 to rotate through the connecting rod 12. When the connecting block 15 rotates, it drives the driving worm 10 to rotate, because the worm wheel 13 is meshed and connected with the driving worm 10, When the driving worm 10 rotates, the threaded rod 7 is driven to rotate through the worm wheel 13. When the threaded rod 7 rotates, the lifting column 3 threadedly connected thereto is driven to move along the axial direction of the threaded rod 7, so that the top plate 4 is driven to adjust the height through the movement of the lifting column 3. When it is adjusted to a suitable height, the rotating handle 9 is pushed, so that the rotating handle 9 drives the connecting block 15 to move in the direction close to the driving worm 10 through the connecting rod 12. When the connecting block 15 moves to the plug-in block 14 and disengages from the plug-in slot, the plug-in block 14 cancels the plug-in connection with the fixed block 11, so that when the rotating handle 9 is rotated, the driving worm 10 cannot be driven to rotate. Due to the self-locking principle between the driving worm 10 and the worm wheel 13, the height of the lifting column 3 will not change. At the same time, it can effectively avoid the situation where the height of the lifting column 3 changes due to accidental rotation of the rotating handle 9;

[0041] When performing an infusion, the bottle is hung on the hook 23. Since the liquid medicine in the bottle is heavy, the bottle drives the movable plate 22 to move downward through the hook 23. When the movable plate 22 moves, it drives the sliding block 24 to move at the same time. As the liquid in the bottle decreases, the movable plate 22 is driven to move slowly upward under the elastic action of the third spring 21. When the movable plate 22 moves to the point where the sliding block 24 contacts the sensor 25, the sensor 25 sends a signal to the controller 19, so that the alarm light 20 is activated through the controller 19, causing the alarm light 20 to emit red and blue light, reminding the patient and medical staff to replace the bottle in time. The alarm time of the alarm light 20 is set to twenty seconds, and it will be turned off after twenty seconds, thereby effectively reminding the medical staff to replace the bottle in time.
