Abstract

The present invention is a medical training apparatus and system is provided for training of medical professionals in ophthalmic examinations based on manipulation of a medical tool. The apparatus may comprise a physical model of an eye having an opening through which an image display is visible that simulates the appearance of an eye during ophthalmoscopy. A modified ophthalmoscope includes movement sensors and captures movement information, which is processed by the system to selectively display corresponding sections of images of an eye. The training apparatus is operable for one or more simulations for training a trainee in a medical examination or procedure for a body part in accordance with a training method.

First claim

We claim:

1. A computer-implemented medical training method, comprising:
(a) one or more users engaging a simulation computer system to initiate an ophthalmic examination training routine by one or more computer processors, the simulation computer system including an eye model, one or more movement sensors, an image display, and a controller for controlling the image display that displays one or more images of an eye, wherein the controller executes one or more smoothing techniques for smoothing a transition between display of a first image section to a second image section;
(b) each of the one or more users moving an ophthalmoscopy tool relative to the eye model while conducting the ophthalmic examination training routine;
(c) detecting movements of the one or more users using the one or more movement sensors to generate input information to the controller; and
(d) the controller iteratively using the input information to select and display a region of interest view from the one or more images of the eye, or the first image section and the second image section, that corresponds to the input information, and to initiate displaying the first image section and the second image section by the image display to simulate an appearance of the eye in connection with the ophthalmic examination training routine across a set of the movements of the one or more users and the input information.

2. The method of claim 1 , wherein the simulation computer system iteratively: (a) detects and processes the movements of the one or more users: (b) selectively displays the first image section and the second image section; and (c) generates a continuous display of the first image section and the second image section that follow the movements of the one or more users based on consecutive detected movements of the set of movements which correspond to the first image section and the second image section to simulate the appearance of the eye during an the ophthalmic examination training routine.

3. The method of claim 1 , comprising the further step of initiating one or more calibration steps for establishing a starting position for the ophthalmic examination training routine.

4. The method of claim 1 , comprising the further step of logging the movements of the one or more users, and comparing the set of the movements of the one or more users to an ophthalmoscopy training profile.

5. The method of claim 4 , comprising the further step of providing feedback to a trainee regarding performance in the ophthalmic examination training routine as compared to the ophthalmoscopy training profile.

6. A medical examination training system for simulating ophthalmoscopy comprising:
(a) a computer system linked to at least one base unit, and including a controller, wherein the controller executes one or more smoothing techniques for smoothing a transition between displaying a first image section to a second image section;
(b) the at least one base unit including or receiving one or more physical models of an eye, the one or more physical models including an opening and an image display viewable through the opening, the opening being configured to enable a trainee to line up a connected ophthalmoscopy device with the opening to view one or more images displayed by the image display, using the connected ophthalmoscopy device;
(c) the computer system defining a starting position and thereafter tracking a series of movements made by the trainee using the connected ophthalmoscopy device, the series of movements defining an ophthalmoscopy examination; and
(d) the computer system processing the series of movements made by the trainee to generate display control data, the controller using the display control data to control the image display to simulate an appearance of a human eye across the series of movements made by the trainee in the ophthalmoscopy examination.

7. The medical examination training system of claim 6 , wherein an image library is linked to the computer system, and the image library contains the one or more images of the eye, and wherein the controller, based on the display control data, selectively displays a particular image section of the one or more images corresponding to the series of movements.

8. The medical examination training system of claim 7 , wherein the image particular section of the one or more images includes one or more landmarks of the eye, and the controller enables the trainee to selectively view the one or more landmarks based on a defined ophthalmoscopy examination.

9. The medical examination training system of claim 6 , wherein the computer system includes a movement detection component that detects the series of movements made by the trainee using the connected ophthalmoscope device relative to the at least one base unit.

10. The medical examination training system of claim 9 , wherein the connected ophthalmoscopy device includes a plurality of diopter settings for selecting a diopter, and the series of movements detected by the computer system include changes made by the trainee selecting the diopter.

11. The medical examination training system of claim 10 , wherein the plurality of diopter settings are used to determine a particular layer of the eye shown in the one or more images displayed by the image display.

12. The medical examination training system of claim 6 , wherein the computer system is configured to train the trainee to identify a medical condition indicated by one or more features shown in the one or more images.

13. The medical examination training system of claim 6 , further comprising a trainer computing device, the trainer computing device implementing one or more trainer features responsive to an input from a trainer for displaying image data and other information to the at least one base unit, each base unit associated with the trainee.

14. The medical examination training system of claim 6 , wherein the computer system enables the trainee to learn how to manipulate an ophthalmoscope in order to conduct the ophthalmoscopy examination, including to locate and recognize certain landmarks of the eye.

15. The medical examination training system of claim 6 , including a feedback component that compares the series of movements to a trainer profile, and provides feedback to the trainee.

16. The medical examination training system of claim 15 , wherein the feedback component provides suggestions to the trainee for conducting the ophthalmoscopy examination.

17. The medical examination training system of claim 6 , comprising a calibration device for defining one or more parameters for the starting position.

18. The medical examination training system of claim 17 , wherein the calibration device includes a magnet.

19. The medical examination training system of claim 6 , wherein the controller is configured to switch between displaying the first image section to displaying the second image section that is adjacent to a field of view of the first image section, based on the display control data.

20. The medical examination training system of claim 19 , wherein the controller smoothes the transition between the first image section and the second image section to simulate the appearance of the human eye during the ophthalmoscopy examination.
