When the user uses this device to suspend the infusion set, firstly, the user hangs the infusion bottle on the head end of the suspension rod 42, and the head end of the suspension rod 42 hangs down due to gravity. Then, the user hangs the infusion tube on the head end of the hook 54, so that the head end of the hook 54 abuts against the top surface of the negative pressure bladder of the infusion tube. As the liquid in the infusion bottle decreases, the suspension rod 42 flips upward under the elastic force of the return torsion spring, thereby driving the infusion bottle and infusion tube to rise. During the process of the infusion bottle rising, the infusion bottle pulls the hook 54 upward through the infusion tube. The movement causes the hook 54 to drive the slider 53 to slide along the guide of the slide groove 52 toward the top of the inner cavity of the slide groove 52. After the infusion liquid in the infusion bottle is finished, the suspension rod 42 drives the infusion bottle to rise to the highest position within the range.

The indicator light 56 ​​lights up after receiving the detection signal, and the buzzer sounds an alarm after receiving the detection signal.

[0073] When the user needs to adjust the extension length of the telescopic rod 2, firstly, the user rotates the top cover 31 counterclockwise to loosen it. During this process, the top cover 31 moves upward along the axial direction of the bearing tube 1, and drives the positioning sleeve 343 to move upward synchronously, causing the top of the positioning sleeve 343 to disengage from the gap between the gasket 342 and the circumferential inner wall of the bearing tube 1. After the gasket 342 loses pressure, it recovers its deformation, thereby preventing the outer surface of the gasket 342 from contacting the circumferential side wall surface of the telescopic rod 2, thus releasing the telescopic rod 2. Then, the user pulls the telescopic rod 2 out of the inner cavity of the bearing tube 1. After the telescopic rod 2 is pulled out to a certain length, or after the user controls the telescopic rod 2 to retract to a certain length into the inner cavity of the bearing tube 1, the user rotates the cap clockwise to tighten the top cover 31 onto the top of the bearing tube 1. During this process, the positioning sleeve 343 moves downward synchronously with the top cover 31, so that the positioning sleeve 343 is fully inserted into the gap between the gasket 342 and the circumferential inner wall of the bearing tube 1. The gasket 342 undergoes elastic deformation after being squeezed by the positioning sleeve 343, thereby sticking tightly to the circumferential side wall surface of the telescopic rod 2. The friction between the telescopic rod 2 and the gasket 342 is used to position the telescopic rod 2.

[0074] Above, refer to Figures 1-6 The infusion care stent according to an embodiment of the present invention has the following beneficial effects:

[0075] 1、The device is locked by setting the rotating locking module relative position between the telescopic rod and the bearing tube, so as to facilitate the user to adjust the extension length of the telescopic rod, enhance the use convenience of the device, solve the defect of poor use convenience in the prior art.

[0076] 2、The device is fixedly provided with the positioning shaft sleeve on the inner wall of the top cover, and the assembly ring and the gasket are arranged in the inner cavity of the bearing tube, the user inserts the positioning shaft sleeve into the gap between the gasket and the circumferential inner wall of the bearing tube by tightening the top cover, and the gasket is pressed by the positioning shaft sleeve, so that the gasket is tightly attached to the telescopic rod, and the telescopic rod is positioned by the friction force between the gasket and the telescopic rod, solving the problem in the prior art that the clamping block needs to be aligned with one of the through holes before being inserted into the corresponding through hole to position the sliding rod during adjustment of the extension length of the sliding rod.

[0077] 3、The device adds an alarm module to prewarn the residual amount of liquid medicine in the infusion bottle, and the hook of the alarm module is connected with the infusion tube, improving the stability of the infusion tube.
