Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an infusion alarm system. Background Art
[0002] The infusion alarm is a technical application in clinical nursing. Its purpose is to solve the problem of repeated passive calls during infusion. Nurses can actively and intuitively see the progress of infusion, thereby reducing their workload.
[0003] Most mature products on the market use weighing solutions, which can display the remaining amount and issue emergency alarms. However, the drawback is that it cannot actively intervene in the infusion process. If you fail to reach the patient in time and fail to remove the needle in time when the infusion is completed, the patient will bleed back, causing harm to the patient and his family. Even if you reach the patient in time, there may be uninfused liquid in the medicine bottle because the remaining amount is inaccurate. On the surface, the weighing alarm can provide information feedback on the infusion, but in fact, because it cannot accurately measure the remaining amount and cannot actively intervene, it will bring additional burden to the infusion.
[0004] The new technology uses infrared rays to record drops of infusion and accurately record the remaining amount of infusion. In conjunction with the active intervention device, it can actively cut off the infusion tube to prevent the patient from bleeding back even if the nurse fails to arrive in time after the alarm.

The dropper controller is connected to the server for communication. The dropper controller is mainly composed of a housing 1, an infrared sensor, an electronic control unit, a display unit, an audible and visual alarm unit, a communication unit, a motor 8, and a knife switch 5. A groove 11 for placing the drip bucket 3 is provided on one side of the housing 1. The knife switch 5 is slidably arranged in the housing 1 and partially extends into the groove 11 to abut against the infusion tube 31 at the output end of the drip bucket.

[0027] like Figure 3 , Figure 4 A flip cover 12 is also provided on the shell of the notch of the groove 11. One side of the flip cover 12 is hinged to the shell through a torsion spring, and the other side is clamped to the shell 1.
[0028] A clamping block 14 is fixedly connected to one side of the flip cover 12 relative to the groove 11, and a photoelectric infrared emitting tube 2A is embedded in the middle of the clamping block 14. A photoelectric infrared receiving tube 2B is correspondingly arranged at the bottom of the groove 11.
