ABSTRACT:
Apparatus for accurately and more safely monitoring blood and bodily fluids in a patient. In one embodiment, at least one load cell supports a container for receiving various sizes of sponges that hold such fluids. The sponges may be sorted into the container utilizing a sorting grip located above or forming a part of the container, and photoelectric or other sensors detect the number of sponges placed into the container via each opening in the grid. The load cells and sensors are connected to controller circuitry which counts, tracks and displays the number of each size of sponges in the container and the weight of fluid in the sponges. The weighing apparatus may be connected to a computer that is programed to read information from the weighing apparatus and from its own keyboard to calculate, update, store, display and print values corresponding to amounts of suction products, urine, crystalloids, irrigation, miscellaneous blood products including whole blood, fresh frozen plasma, packed red blood cells, platelets, cryoprecipitates and stimates introduced to or removed from the patient. The processor of the weighing apparatus may be adapted to perform the computer's functions in order to reduce the size of the apparatus. Alternatively, a computer without a weighing apparatus may be used to account for the values mentioned above, in which case the operator manually enters information relating to numbers and weights of sponges.
