Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a patient infusion flow rate regulating device. Background Art

[0002] An infusion set is a common medical consumable. After sterilization, it establishes a channel between the vein and the medicine and is used for intravenous infusion. Studies have shown that during infusion, adjusting the rate too fast or too slow, which deviates from the pre-infusion rate, will have an adverse effect on the patient.

[0003] When the existing infusion device is in use, usually only a flow rate regulator is set on the side close to the patient. Although it can meet the daily use needs, for some infusion users who lack medical safety knowledge and do not attach importance to the importance of maintaining a specific infusion rate, they usually secretly increase the set infusion rate in order to meet their own needs of completing the infusion quickly after the doctor leaves, which may cause the final infusion treatment effect to deviate and even cause medical accidents.
