[0030] The specific settings and functions of its adjusting device 2 and auxiliary device 3 will be specifically described below.

[0031] Refer to Figure 2 and Figure 3 As shown, in this embodiment: The adjusting device 2 includes a fixed frame 201. The fixed frame 201 is fixedly connected to the roller 5. A rotating groove 202 is opened on one side of the fixed frame 201 close to the roller 5. A connecting frame 203 is rotatably connected to the inner wall of the rotating groove 202. A limiting frame 204 is fixedly connected to the side of the connecting frame 203 away from the roller 5. A moving plate 205 is fixedly connected to the side of the limiting frame 204 away from the connecting frame 203. A fixing rod 206 is threadedly penetrated through the inner wall of the moving plate 205. A turntable 207 is fixedly connected to the side of the fixing rod 206 away from the limiting frame 204. An infusion regulator is a medical device. The infusion regulator can be used to adjust and control the infusion speed to ensure that the liquid in the infusion tube enters the patient's body at a predetermined flow rate. However, the angle of the existing infusion regulator after adjustment cannot be fixed. This also causes the infusion regulator to be adjusted when accidentally touched by a person, resulting in inaccurate infusion measurement. There is a situation where the infusion is too fast or too slow during infusion, affecting the safety of the patient during infusion. At this time, the angle of the adjusted infusion regulator can be locked by the adjusting device 2, so as to improve the stability of the infusion regulator in adjusting the infusion speed by locking the adjustment angle of the infusion regulator, reduce the accidental touch of personnel, and prevent the poor stability effect after the infusion regulator is adjusted. A telescopic rod 208 is fixedly connected to the side of the moving plate 205 away from the limiting frame 204. One end of the telescopic rod 208 away from the moving plate 205 is fixedly connected to a protective frame 209. The inner wall of the protective frame 209 is rotatably connected to the turntable 207. When fixing the angle of the roller 5 through the turntable 207 and the fixing rod 206, the protective frame 209 installed on the telescopic rod 208 can reduce the area of the turntable 207 exposed to the outside, so as to avoid accidentally touching the turntable 207 through the protective frame 209 and affecting the stability of fixing the roller 5. A plurality of anti-slip grooves 210 are opened on the arc surface of the turntable 207. The plurality of anti-slip grooves 210 are evenly distributed on the arc surface of the turntable 207. When rotating the fixing rod 206 through the turntable 207, the anti-slip grooves 210 opened on the turntable 207 can improve the efficiency of the turntable 207 during rotation, so as to improve the speed of rotating the turntable 207 through the anti-slip grooves 210. A support frame 211 is fixedly connected to the side of the connecting frame 203 close to the limiting frame 204. When the connecting frame 203 rotates in the rotating groove 202, the support frame 211 installed on the connecting frame 203 can improve the stability of the connecting frame 203 rotating in the rotating groove 202, so as to improve the effect of the connecting frame 203 rotating in the rotating groove 202 through the support frame 211.

When the infusion regulator is damaged, the infusion regulator can be detached from the infusion tube through the auxiliary device 3, so that it is convenient to detach the infusion regulator from the infusion tube through the auxiliary device 3, and the efficiency of replacing the damaged infusion regulator is improved. A guiding block 36 is fixedly connected to the end of the limiting rod 35 away from the second outer shell 4, the guiding block 36 is funnel-shaped. When the connecting ring 34 contacts the limiting rod 35, the guiding block 36 installed on the limiting rod 35 can improve the connection speed between the connecting ring 34 and the limiting rod 35, so that the connection efficiency between the connecting ring 34 and the limiting rod 35 can be improved through the guiding block 36. A connecting pad 37 is fixedly connected to one side of the connecting ring 34 close to the second outer shell 4, and the cross-section of the connecting pad 37 is arc-shaped. When the connecting ring 34 contacts the elastic piece 33 through the limiting rod 35, the connecting pad 37 installed on the connecting ring 34 can improve the friction force when the connecting ring 34 contacts the elastic piece 33, so that the contact stability between the connecting ring 34 and the elastic piece 33 can be improved through the connecting pad 37.

[0033] Detailed usage method: When it is necessary to lock the adjusted angle of the infusion regulator, by sliding the roller 5 in the first outer shell 1 and the second outer shell 4, the roller 5 can be used to squeeze the infusion tube body, so that the flow rate of the infusion tube can be adjusted by adjusting the roller 5. When the roller 5 moves, the roller 5 will drive the fixed frame 201 to move together. The connecting frame 203 will rotate in the rotating groove 202 opened on the fixed frame 201. The movement of the connecting frame 203 will drive the limiting frame 204 and the moving frame to slide on one side of the first outer shell 1. After the roller 5 is adjusted to a suitable position, the fixed rod 206 installed in the moving plate 205 can be rotated through the turntable 207, so that the fixed rod 206 can contact one side of the first outer shell 1, thereby limiting the movement of the roller 5.

[0034] When it is necessary to replace the damaged infusion regulator, detach the damaged infusion regulator from the infusion tube, connect the inner wall of the first outer shell 1 to the infusion tube, and then make the second outer shell 4 contact the first outer shell 1 through the infusion tube. At this time, the elastic piece 33 can be pulled in the direction away from the first outer shell 1, and the elastic piece 33 will deform during movement. Connect the deformed elastic piece 33 to the limiting rod 35 installed on the second outer shell 4. At this time, the connecting ring 34 can be rotated on the limiting rod 35, and the movement of the connecting ring 34 will fix the elastic piece 33 on the second outer shell 4, so that the new infusion regulator can be fixed on the infusion tube.
