Solution Overview

Problem

Current medical simulation methods are not sufficiently realistic, costly, and require dedicated hardware, limiting their flexibility and practicality for training medical personnel, especially since they often rely on artificial data and cannot be used in the actual clinical environment.

Innovation Solution

A method that allows any medical device to be transformed into a simulator by intercepting sensor input data and replacing it with simulated data, enabling realistic training on the actual device in its intended environment without the need for additional hardware, using a processor to generate user outputs based on simulation signals that mimic real clinical parameters.

AI summary

A method and apparatus for implementing a simulation mode on a medical device, the medical device arranged in a normal operating mode to receive sensor input data, and to generate a sensory output based on the data. The method is based on taking control of the medical device to interrupt the flow of data between the sensor inputs and a monitoring processor of the medical device, and inputting to the processor, in place of the sensor input data, simulation signal data.
