1. A medical liquid feeding unit comprising:
- a medical liquid feeding device including an expandable container, an inlet port for supplying a medical liquid into the expandable container therethrough, and a feed duct for feeding to a patient the medical liquid discharged from one end of the expandable container by a contractive force of the expandable container, the medical liquid feeding device further including a hung member;
a medical liquid meter for quantifying a remaining amount of the medical liquid stored in the expandable container, the medical liquid meter including a weight-measuring device for measuring the weight of the medical liquid feeding device and a suspender provided on the weight-measuring device, the suspender being configured for disengageably engaging the hung member for suspending the medical liquid feeding device, and the weight of the medical liquid feeding device being measured under a condition that the medical feeding device is suspended by the suspender; and
a cord-shaped connection member adapted, when the suspender is disengaged from the medical liquid feeding device, to maintain the connection between the medical liquid meter and the medical liquid feeding device therethrough.

Abstract
Disclosed is a medical liquid meter (10) for use with a medical liquid feeding device (30) including an expandable container (31), an inlet port (32) for supplying a medical liquid into the expandable container (31) therethrough, and a feed duct (33) for feeding to a patient the medical liquid discharged from one end of the expandable container (31). The medical liquid meter (10) comprises a weight-measuring mechanism (1). The weight of the medical liquid feeding device (30) is measured using the weight-measuring mechanism (1) so as to quantify a remaining amount of the medical liquid stored in the expandable container (31).
