Description

Technical Field

[0001] The utility model belongs to the field of infusion drop number regulation, in particular to an infusion device which can automatically control the infusion drop number. Background Art

[0002] Infusion tube drip rate adjustment is a common operation in the medical field, which is used to control the speed of intravenous infusion. Intravenous infusion is the insertion of drugs, liquids or nutrient solutions into the veins through infusion tubes so that they can be quickly delivered to the patient's blood circulation; the purpose of infusion tube drip rate adjustment is to ensure that the drugs or liquids are delivered to the patient at an appropriate speed to meet the needs of treatment; the drip rate can be adjusted by adjusting the drip frequency of the infusion tube, and the common unit is the number of drops per minute;

[0003] The existing method of adjusting the number of drops is usually to manually operate the adjustment wheel on the infusion tube, and the delivery tube will be automatically closed when there is no drop in the drip pot; there are also solutions that use automatic control of the number of drops, such as gravity infusion devices, which use infrared sensors to identify the infusion speed in the drip pot, and then manually operate the adjustment wheel on the infusion tube;

[0004] The adjustment methods in the above schemes all require manual adjustment of the speed control, and cannot automatically control the number of drops;

[0005] Therefore, those skilled in the art have proposed an infusion device capable of automatically controlling the number of infusion drops to solve the problems raised in the background art. Utility Model Content
