Description

Technical Field

[0001] This utility model relates to a control device, and more particularly to a control circuit for a shared infusion controller management cabinet. Background Technology

[0002] In the existing technology, in order to prevent dangerous situations such as air entering the vein or blood backflow, an infusion controller is installed on the infusion tube. When the medication is finished dripping, the infusion controller can automatically stop the infusion tube. Patients do not need to keep an eye on the infusion bottle at all times. For patients who are unattended, in intensive care, receiving long-term infusions, or bedridden, this can reduce anxiety caused by infusion problems.

[0003] Infusion controllers are typically managed and maintained by nurses. Most infusion controllers on the market are independently charged, drawing power from a charging base. Since each charging base requires a socket, charging multiple infusion controllers simultaneously would necessitate several power sockets. This lack of centralized management can lead to scattered and disorganized placement of the infusion controllers, making them difficult to manage and increasing the burden on nurses.
