US 2025/0160656 A1 · FLUID LOSS ESTIMATION BASED ON WEIGHT OF MEDICAL ITEMS

Abstract

A computer-implemented method for quantifying blood on one or more absorbent items is provided. The method includes receiving data indicative of a quantity of each type of the absorbent items to be used in a medical procedure, accessing a dry weight for each type of the absorbent items, and determining a total dry weight based on the dry weight for each type of the absorbent items. Measurement signals are received from a scale measuring the absorbent items containing blood. An occurrence of a weighing event may be determined using a machine learning algorithm trained on a training data set of scale signal patterns. A wet weight of the absorbent items associated with the weighing event is received. A volume of blood contained in the absorbent items is determined based on the wet weight and the total dry weight. The volume of blood is displayed on a display.

A computer-implemented method for quantifying blood on one or more absorbent items, the method comprising:

receiving data indicative of a quantity of each type of the absorbent items to be used in a medical procedure;
accessing a dry weight for each type of the absorbent items;
determining a total dry weight based on the dry weight for each type of the absorbent items;
receiving measurement signals from a scale measuring the absorbent items containing blood;
determining an occurrence of a weighing event by analyzing the measurement signals to identify a scale signal pattern using a machine learning algorithm trained on a training data set of scale signal patterns corresponding to weighing events and non-weighing events;
receiving a wet weight of the absorbent items associated with the weighing event;
estimating a volume of blood contained in the absorbent items based on a difference between the wet weight of the absorbent items and the total dry weight of the absorbent items;
and
displaying the volume of blood on a display.
