Triton System

The Triton System is a mobile medical application employing image processing technology on an iPad to provide clinicians with quantitative estimates of blood loss from surgical sponges and aid in sponge management. Its methodology involves capturing sponge images, analyzing them for hemoglobin content to calculate blood volume, and integrating data from various sources to support perioperative decision-making and patient safety.

The Triton System is a software application designed as an adjunctive tool for surgical teams to estimate external blood loss and manage surgical sponges. Operating on an Apple iPad® tablet, it utilizes image processing technology to analyze images of used surgical sponges, thereby estimating the hemoglobin (Hb) mass contained on them. Based on this Hb mass and a user-inputted patient serum Hb value, the system calculates an estimated blood volume lost on the sponges. Additionally, the Triton System assists in counting surgical sponges, provides a visual record of sponge images, and can record user-entered weights of used sponges to estimate fluid volume. This iteration of the Triton System integrates blood loss estimations from both sponges and canisters (from a reference device) onto a single display for comprehensive monitoring. It offers an enhanced method for users to manually input estimated blood loss (EBL) for situations like oversaturated sponges, considering specific sponge fluid capacities, and includes a read-only "View-Only Mode" for monitoring EBL events. The system's functionality extends to supporting additional validated sponge types, including non-square ones, and a new Bluetooth foot pedal. Its scientific basis relies on image processing algorithms to quantify hemoglobin from sponge images, with performance validated under various conditions and its software displaying cumulative error estimates based on methods like Bland-Altman analysis.
