Devices (10) for monitoring fluids removed from patients, such as in surgery. A load cell (30) automatically senses the weight of fluid in a conventional or a non-conventional canister (14) supported by the load cell (30). The load cell (30) outputs or modifies signals corresponding to such loads, which are received by a controller (34). The controller (34) computes values corresponding to weight and volume of fluid in the canister (14) and supplies signals corresponding to such values, including, if desired, cumulative values, to output for display (58), storage, or use by external devices such as through a serial port. The controller (34) is adapted automatically to tare the weight of the canisters (14) and loads imposed by flexible tubing (15) connected to the canisters (14), and automatically to "hold" values corresponding to a liner (16) that has been removed (should it become full) so that the monitoring process may be resumed when a new, empty canister (14) is supplied. |
