Title:
流量監視装置、輸液装置及び異常報知方法
Document Type and Number:
Japanese Patent JP6981341
Kind Code:
B2
Abstract:
To reduce false notification of flow volume abnormality occurring when a patient moves, in a flow volume monitoring device for infusion.SOLUTION: A flow volume monitoring device 1 used for infusion device 100 comprises: a droplet fall sensor part 20 detecting a droplet falling in a drip cylinder 210; an acceleration sensor 30 detecting a movement state of the drip cylinder 210; a notification part 40 notifying a user of abnormality; and a sensor side control part 50 controlling the notification part 40 on the basis of the number of droplets detected by the droplet fall sensor part 20 and acceleration information detected by the acceleration sensor part 30. The sensor side control part 50 determines whether the drip cylinder 210 is moved or is at rest based on the acceleration information, and when the number of droplets per unit time exceeds a prescribed threshold, determines that flow volume is abnormal and actuates the notification part 40, and uses, as the prescribed threshold, a first threshold when the drip cylinder is at rest and a second threshold larger than the first threshold when the drip cylinder moves.SELECTED DRAWING: Figure 2
