[0002] In existing medical nursing practice, clinical infusion stents are important medical devices used to support and fix infusion bottles for infusion therapy. Existing clinical infusion stents have the following problems: (1) Traditional clinical infusion stands usually only provide simple support functions. During infusion therapy, patients usually need to notify the nurse to replace the infusion bottle when they see that the medicine is about to run out, in order to ensure the continuity and safety of treatment. However, when multiple patients need to change the medicine at the same time, it is easy to make mistakes and replace it in time. (2) Failure to properly remove the air from the infusion tube when replacing the infusion bottle may result in air embolism, posing serious health risks to the patient. Summary of the invention

[0018] In this embodiment, the medical staff inserts the infusion connector of the infusion tube into the infusion tube fork 292, and places the infusion bottles that the patient needs infusion in order in the infusion bottle placement mechanism 3, with the infusion bottle mouth facing downward through the first through hole 311 and the second through hole 331, and the top of the infusion connector of the infusion tube is inserted into the infusion bottle. The gravity of the infusion bottle applies downward pressure to the elastic sensing plate 33, compressing the sensing spring 35, so that the top of the infusion bottle is away from the first touch switch 23, and the limiting plate 32 limits the infusion bottle to prevent the infusion bottle from shaking and falling off. As the liquid in the infusion bottle gradually decreases, the sensing plate 33 is pressed downward. The spring 35 is reset, and the elastic sensing plate 33 slides upward along the first sliding shaft 34, driving the infusion bottle to move upward. The limit plate 32 can guide the infusion bottle at this time. When the liquid inside the infusion bottle is empty, the top of the infusion bottle contacts the first touch switch 23, and the driving motor 271 is started to rotate. The driving motor 271 drives the transmission shaft sleeve 272 and the transmission gear 273 to rotate.

The transmission gear 273 meshes with the first driven gear 25, driving the driven shaft sleeve 24 and the infusion bottle to rotate, thereby realizing the switching of the infusion bottle. At the same time as the transmission gear 273 meshes with the first driven gear 25, the transmission gear 273 meshes with the second driven gear 282 remains in the meshing state, and under the continuous rotation of the driving motor 271, the slider 291 moves upward, and the transmission pressure rod 42 moves upward under the action of the slider 291, and the moving force is transmitted to the U-shaped pipe 41 through the transmission pressure rod 42, thereby applying suction to the liquid in the U-shaped pipe 41, and the driven guide rod 43 and the transmission gear 273 move downward, and the transmission gear 273 and the first driven gear 25 are released from meshing. After completing the switching of the infusion bottle, the slider 291 continues to move upward to the top, and at this time the infusion connector of the infusion tube is inserted into the new infusion bottle.

[0019] Example 2: This example is based on Example 1. Please refer to Figure 1 , Figure 2 , Figure 8 and Fig. 9In this embodiment, a second sliding shaft 2611 is fixedly provided at one end of the slide rail frame 261 away from the slider 291, and a first L-shaped connecting rod 2612 is slidably engaged and connected on the second sliding shaft 2611.

A second L-shaped connecting rod 2911 is fixedly provided on the side wall of the slider 291, and the second L-shaped connecting rod 2911 movably contacts with the arc-shaped protrusion 2614.

[0020] The drip bucket of the infusion tube is located on the side wall of the mounting plate 26. A notch 263 for accommodating part of the drip bucket can be provided on the side wall of the mounting plate 26. When the slider 291 continues to move upward to the top, the second L-shaped connecting rod 2911 moves upward and contacts the arc-shaped protrusion 2614, pushing the first L-shaped connecting rod 2612 away from the slide rail frame 261. When the infusion connector of the infusion tube is inserted into a new infusion bottle, the second L-shaped connecting rod 2911 is disengaged from the arc-shaped protrusion 2614. Under the action of the oscillation spring 2615, the first L-shaped connecting rod 2612 and the pressure plate 2613 are driven to oscillate back and forth. During the oscillation, the pressure plate 2613 squeezes the drip bucket of the infusion tube, pushes the liquid in the tube, and discharges the air from the infusion tube.
