Abstract
The invention provides an infusion liquid level monitoring system and method. The infusion liquid level monitoring system comprises a shell, and the shell is provided with a monitoring groove used for containing a drip chamber. The infusion liquid level monitoring system further comprises a detection ray transmitting device and a detection ray receiving device which are used for detecting height changes of the liquid level in the drip chamber, and the detection ray transmitting device and the detection ray receiving device are located at the two sides of the monitoring groove respectively. The infusion liquid level monitoring system has the advantages that monitoring of the height of the liquid level in the drip chamber is achieved by utilizing total reflection of detection rays at the set liquid level in the drip chamber, so an infusion process can be effectively monitored; whether the axial direction of the drip chamber is perpendicular to the horizontal plane or not is detected by utilizing a gravity sensing device, so it can be ensured that the liquid level in the drip chamber is perpendicular to the axial direction of the drip chamber; an alarm can be given only when the gravity sensing device detects that the duration time when the axial direction of the drip chamber is not perpendicular to the horizontal plane exceeds a set threshold value, and therefore a false alarm caused by slight shaking of the drip chamber is avoided.
