[0034] Working principle: Before use, hang the infusion bottles with different liquid levels about to reach the bottom on the infusion hook 203 at one end of the rotating seat 202 in sequence, and ensure that the infusion set connected below is in a liquid-filled state during infusion. Then twist the twist plate 501 to ensure that the infusion hook 203 is exactly in a straight state each time, and record the readings at the notch 509 for each different liquid as a reference number; During installation, the infusion bottle is hung on the infusion hook 203 at one end of the rotating seat 202, and then the torsion plate 501 is twisted so that the reading notch 509 is located at the control number of the medicine solution. At this time, the gravity of the infusion bottle drives the rotating seat 202 to rotate, and the infusion hook 203 at one end of the rotating seat 202 is pulled to a vertical state. When the rotating seat 202 rotates, it drives the active synchronous wheel 206 to rotate synchronously through the upper rotating shaft 204. When the active synchronous wheel 206 rotates, it drives the driven synchronous wheel 207 to rotate through the synchronous belt 208. The driven synchronous wheel 207 drives the driven synchronous wheel 207 through the lower rotating shaft 205. The inner support collar 402 tightens the spiral spring 404 to store force. At the same time, the movement of the synchronous belt 208 drives the first counterweight 301 to slide upward. The first counterweight 301 drives the lower connecting column 309 and the connecting slider 310 to rise through the extended connecting block 303, so that the extended column 311 rises, and the reference cursor 312 rises from the zero scale of the scale reference groove 108 to the highest scale. After the infusion set is installed and the needle is inserted, the hose above the liquid bag is clamped to the surface of the anti-slip pad 106 to form a support to avoid dragging below the infusion set to affect the accuracy of the device, and then wait for infusion; During infusion, as the liquid inside the infusion bottle decreases, the weight of the medicine inside the infusion bottle gradually decreases, and the pressure on the spiral spring 404 gradually decreases. The elastic force of the spiral spring 404 is gradually released and pushes the inner support ring 402 to gradually rotate and reset. When the inner support ring 402 gradually rotates and resets, it will drive the driven synchronous wheel 207 through the lower rotating shaft 205, and then drive the synchronous belt 208 to move in the opposite direction, and then drive the first counterweight block 301 to slide down. The first counterweight block 301 drives the lower connecting column 309 and the connecting slider 310 to descend through the extended connecting block 303, so that the extended column 311 descends, and the control cursor 312 moves from the highest scale main line of the scale control slot 108 to the zero scale. When the liquid level reaches the specified position, the control cursor 312 also happens to reach the zero scale. Therefore, the patient can timely obtain the degree of liquid level drop through the control cursor 312; When twisting the torsion plate 501, the greater the twisting angle of the torsion plate 501, the greater the twisting angle of the outer supporting ring 403 is, the greater the winding degree of the spiral spring 404 is, the greater the elastic force is, and the weight of the infusion bottle is also greater when overcoming the spiral spring 404. Therefore, the initial elastic force of the spiral spring 404 can be adjusted according to the different weights of different medicines in the infusion bottle to ensure that the elastic force of the spiral spring 404 pushing it when the liquid level of different infusion bottles is about to bottom is just enough to ensure that the rotating seat 202 is straight. When twisting the torsion plate 501, the one-way ratchet 508 is driven to rotate synchronously. When rotating to a specified angle, the ratchet pawl 505 is moved to form an engagement limit on the one-way ratchet 508 to prevent it from rotating. When resetting, pressing the ratchet pawl 505 to separate it from the one-way ratchet 508, and the reaction force of the spiral spring 404 will push the torsion plate 501 and the one-way ratchet 508 to reset through the outer supporting ring 403.
