Abstract

This invention relates to a simulator for training medical teams, the members of which are located in different places, or stations, as they train together using apparatus in coordinated fashion in relation to a numerical data, or virtual, non-physical model without input from a live instructor, wherein each remote station provides a differentiated input with a plurality of differentiated devices, and receives differentiated feedback from the model to each individual station in representations which are visual, tactile, aural, and/or olfactory in their display, depending on the feedback required by each individual station.

Claims

1. A virtual simulator for the training of medical teams in the coordinated treatment of a single patient comprising:

(a) An event-driven state model of the virtual patient governed by a rule-based expert system in software which is replicated at each station, and

(b) a plurality of input/output stations;

(1) each representative of a function to be performed by a team unit,

(2) each station comprised of a plurality of data receivers to receive differentiated data from others of said stations,

(3) each station with at least one representative output means on location, and

(4) each station able to process and send differentiated data to other stations via a data transmitter,

(5) each station with at least one manual input means on location, and

(6) each station with memory means and data processing means to hold and modify the event-driven state model.

2. A virtual simulator for the training of medical teams in the coordinated treatment of a single patient as in claim 1, using a central processor as one unmanned station for the first memory means holding the entire event-driven state model of the patient in software, and monitoring changes through an expert system existing only in the central computer.

3. A virtual simulator for the training of medical teams in the coordinated treatment of a single patient as in claim 2, but with the central processor located at one of the team stations.

4. A virtual simulator for the training of medical as in claim 1, but with a plurality of virtual patients, as in a catastrophic accident.

5. A virtual simulator as in claim 1, wherein the input apparatus has moving means.

6. A virtual simulator as in claim 1, wherein the input apparatus is responsive to position and actuation of said implement.

7. An apparatus as in claim 6, wherein said instruments are selected from a group consisting of:

defibrillator, ventilator, intravenous system. chest compressor, scissors, irrigator, stapler, cutter-stapler, grasper, suction device, circular stapler, flexible endoscope, injection catheter, biopsy catheter, cautery snare catheter, balloon catheter, stent-placement catheter, rotating-blade catheter, drill, routing tool, cutting laser, sealing laser, mechanical sewing tool, bridling tool, probe, camera, needle and thread, scalpel, canulla.

8. A virtual simulator as in claim 5, wherein the input apparatus also gives output to the team unit in visual, tactile, aural, or olfactory representations.

9. A virtual simulator as in claim 1, where at least one team member wears a head-mounted display.

10. A virtual simulator as in claim 1, wherein instructors or other monitors can watch a plurality of team member'"'"'s performance from various stations.

11. A virtual simulator as in claim 1, wherein an instructor or an administrator can define parameters of the simulation before it begins.

12. A virtual simulator as in claim 1, wherein one or more stations can be absent, and its role be played by the computer.

13. A virtual simulator as in claim 1, which is capable of operation in various networked modes, including wire transmission, satellite transmission, broadcast and narrowcast transmissions, and internet, intranet, extranet or other environments for networking remote stations over any given distance.

14. A virtual simulator as in claim 13, which uses parallel communication modes between the team members such as direct video or audio communications.

15. A virtual simulator as in claim 1, with a third memory means to accumulate performance data for remediation and performance profiles.

16. A virtual simulator as in claim 1, with a rule-based expert system to monitor and screen various team performance actions in relation the medical task presented.

17. A virtual simulator as in claim 1, with a state model in software which changes in real time based on selected event input from stations.

18. A virtual simulator as in claim 1, with a duplex or dual-track means of transmission of each event to and from the state model for the purpose of modifying the state model in real time.

19. A virtual simulator as in claim 1, with at least one means of parallel communication between stations which does not become an event that modifies the state model.

20. A virtual simulator as in claim 1, with a rule-based expert system which filters the event inputs to correctly identify the said output display representations for said stations by any visual, aural, tactile, and/or olfactory means.
