Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to an infusion mixer. Background Art

[0002] At present, the existing infusion method in clinical practice is to hang an infusion bag, an infusion bottle or other infusion container (hereinafter referred to as the infusion bag) on ​​an infusion stand, and the infusion bag is in a stationary state for infusion. This method may cause precipitation of the drug solution for suspension drugs such as blood products, cell products, blood transfusion, platelet transfusion, nutrient solution, etc., resulting in uneven drug concentration during the infusion process. Before infusion of this type of drug, the infusion bag needs to be repeatedly turned upside down or gently shaken several times to prevent drug precipitation, so that the liquid inside the infusion bag can be mixed before infusion. During the infusion process, the solution bag should also be gently shaken from time to time to mix it. The purpose of mixing is to make the suspension inside the bag in a uniform state.

[0040] Working principle:

[0041] According to the height requirement of infusion, the length of the inner tube 3 inserted into the outer tube 4 is adjusted to adjust the overall height of the telescopic rod. Finally, by rotating the limit knob 27, the limit knob 27 is pressed against the outer wall of the inner tube 3, thereby fixing the relative position of the inner tube 3 and the outer tube 4, and then determining the height of the telescopic rod.

[0042] The upper end of the infusion bag 31 is hung on the limiting rod 7 of the swing plate 6, and the infusion tube 32 of the infusion bag 31 passes through the T-shaped opening 9 and the arc-shaped limiting ring 29.

[0043] Before infusion, the motor 11 is started, and the output shaft of the motor 11 drives the connecting rod 12 to rotate by rotating, and the connecting rod 12 drives the transmission rod 13 to rotate during the rotation process, and the transmission rod 13 drives the connecting column 15 to rotate during the rotation process, thereby driving the swing plate 6 to rotate, and the swing plate 6 is realized by adjusting the forward and reverse rotation of the motor 11 to realize the swing back and forth swinging, and the swing plate 6 is realized by setting the speed of the motor 11 to realize the swing speed of the swing plate 6. The swing plate 6 realizes the mixing of the solution inside the infusion bag 31 by swinging back and forth, so that the solution in the infusion bag 31 can reach the level for infusion. If precipitation is found in the solution of the infusion bag 31 during the infusion process, the infusion can be suspended first, and the motor 11 can be started to mix the solution in the infusion bag 31 again before infusion. Because the arc-shaped limit ring 29 can fix the infusion tube 32, the needle at the end of the infusion tube 32 will not shake, and the safety and stability are high, saving the labor of the nurse to manually shake the infusion bag 31, and improving the work efficiency.
