摘要

PROBLEM TO BE SOLVED: To notify an operater of that the end of a liquid chemical is close when the liquid chemical inside an intravenous drip container is close to the end. ;SOLUTION: A spring, a storage device 23 and a sensor 10 are turned to a main body and the spring is used for the method of operating the sensor 10. In the storage device 23, a total weight value for which the three points of the weight of the liquid chemical 30, the weight of the intravenous drip container 28 and the weight of a tube 33 are added gathered with a notifying weight value required at the time of notification is turned to a set of units and many possible execution units used in intravenous drip treatment are stored. The sensor 10 selects one unit of the total weight value for which the three points are added from the storage device 23 at the start of the intravenous drip treatment, and when a liquid chemical residual amount value approaches the end in the progress of the treatment, by the judgement of the storage device 23 from the change of the output value of the sensor 10, the end notifying signal of the selected one unit is given from this device.;COPYRIGHT: (C)1998,JPO
