US 8,162,668 B2 · Medical training simulator including contact-less sensors

Abstract

A medical training simulator includes contact-less sensors and corresponding detection objects, configured to enable sensor data collected during a training exercise to be used to evaluate the performance of the training exercise. The simulator includes a simulated anatomical structure, at least one contact-less sensor, and at least one detection object. During a training exercise, a spatial relationship between the contact-less sensor and the detection object produces data for evaluating performance of the training exercise. Either the contact-less sensor or the detection object is embedded in the simulated physiological structure, while the other is included in either a support for the simulated physiological structure, or as part of a tool used during the training exercise. Many types of contact-less sensors can be employed, including capacitance sensors, impedance sensors, inductive sensors, and magnetic sensors.

(a) a contact-less sensor;
(b) a detection object adapted to trigger the contact-less sensor;
(c) a simulated physiological structure configured to visually and tactilely resemble an anatomical structure;

A method for evaluating a performance of a simulated medical procedure, comprising the steps of:

(a) performing the simulated medical procedure, wherein proper performance of the simulated medical procedure requires moving a tool including a plurality of contact-less sensors relative to a first portion of a training model, a second portion of a training model, and a third portion of the training model, the tool generating a signal only when the tool is proximate a predefined portion of the training model related to the simulated medical procedure, each such predefined portion being designated with a detection object, the tool generating a first signal uniquely identifying the first portion of the training model when a first detection object is sensed by a first sensor as the tool is proximate the first portion of the training model, generating a second signal uniquely identifying the second portion of the training model when a second detection object is sensed by a second sensor as the tool is proximate the second portion of the training model, and generating the first and second signals uniquely identifying the third portion of the training model when a third detection object is sensed by the first sensor as the tool is proximate the third detection object and a fourth detection object is sensed by the second sensor as the tool is proximate the fourth detection object, wherein the first and second signals are not identical, the first signal only being generated when the tool is proximate the first or third detection objects, and the second signal only being generated when the tool is proximate the second or fourth detection objects;
(b) collecting sensor data during the performance of the simulated medical procedure, wherein the sensor data are collected without requiring physical contact between the tool and any of the first, second, third, and fourth detection objects;
and
(c) using the sensor data to evaluate the performance of the simulated medical procedure, including the steps of:
(i) determining if the tool was proximate the first portion of the model during an appropriate portion of the simulated medical procedure as indicated by the first signal then being included in the sensor data;

and
(iii) determining if the tool was proximate the third portion of the model during an appropriate portion of the simulated medical procedure as indicated by the first signal and the second signal then being included in a segment of the sensor data that indicates the tool is proximate the third portion of the model.
