Abstract

An interactive, computerized education system for teaching patient care includes an interactive computer program for use with a simulator, such as a manikin, and virtual instruments for performing simulated patient care activity under the direction of the program. The program displays a selection of modules to assist a user in learning patient care protocols, the modules being selectable by the user for providing different interactive training sessions involving the protocols. The virtual instruments are used with the simulator in performing the patient care activity, the virtual instruments cooperating with sensors that interface with the computer program for providing feedback to the program regarding the activity and confirming proper placement and use of the virtual instruments on the simulator.

Claims

1. An interactive, computerized education system for teaching patient care, comprising:

a computer program, for execution on a computer, that displays a selection of modules to assist a user in learning patient care protocols, the modules being selectable by the user for providing different interactive training sessions involving the protocols;

a physiological simulator for receiving simulated patient care activity responsive to the sessions; and

a plurality of different virtual instruments for use with the simulator in performing the patient care activity, the virtual instruments cooperating with corresponding sensors that interface with the computer program for providing feedback to the program regarding the activity during the sessions, such that in providing the feedback, the sensors complete an electrical circuit that confirms proper use of the virtual instruments on the simulator; and

an interface module for interfacing the sensors with the computer program, the module comprising lines each coupled with one of the sensors and a processor coupled with the sensor lines for receiving signals from the sensors and converting the signals to inputs for the computer program.

2. The system of claim 1 wherein said different virtual instruments are selected from the group consisting of an IV needle, an endotracheal ("ET") tube, an electrocardiogram ("EKG") monitor, a blood pressure ("BP") cuff, a pulse oximeter finder cuff, a temporary external pacer, an automatic external defibrillator ("AED") and manual defibillators.

3. The system of claim 1 wherein at least one of the sensors is connected to the simulator.

4. The system of claim 1 wherein at least one of the sensors is connected to one of the virtual instruments.

5. The system of claim 1 wherein the sensors further confirm proper operation of the virtual instruments on the simulator.

6. The system of claim 1 wherein the computer program modules comprise:

teaching modules for providing training sessions that display information on techniques for treating victims in accordance with the protocols; and

testing modules for providing training sessions that evaluate the ability of the user to perform the techniques described in the teaching modules on the manikin in accordance with the protocols.

7. The system of claim 1 wherein the computer program modules provide the training sessions in a self guiding format using graphics buttons that respond to a point-and-click computer user interface.

8. The system of claim 1 wherein the computer program modules include a test module comprising:

a menu of selectable scenarios each of which scenarios requires a different treatment protocol to be administered during the course of treating a victim; and

a presentation of a series of events pertaining to a selected scenario, each event including a description of the event accompanied by a plurality of possible treatment choices to be made in response to the event, at least one of which choices is correct according to the treatment protocol for the scenario, such that the user must enter the correct choice or choices before the next event in the series will be presented.

9. The system of claim 8 wherein the event series presentation of the test module further comprises an indication following the choice entry of whether the entered choice is correct and if not, for displaying an explanation of why the entered choice is not correct.

10. The system of claim 8 wherein the test module further comprises a timer for indicating to the user failure to enter a correct choice within a predetermined time period for the event.

11. The system of claim 8 wherein the test module further comprises a display of a victim electrocardiogram (EKG) corresponding to the event.

12. The system of claim 8 wherein the test module further comprises a display of victim vital signs corresponding to the event.

13. The system of claim 8 wherein the test module further comprises:

a selection for enabling or disabling the virtual instruments during presentation of the selected scenario;

such that when enabled, for events requiring performance of an activity on the simulator, the user entry of the correct choice or choices requires the user to perform the activity on the simulator using the at least one virtual insentient; and

such that when disabled, for events requiring performance of an activity on the simulator, the user may complete an event in the selected scenario without performing the activity.

14. An interactive, computerized education system for teaching patient care, comprising:

a computer program, for execution on a computer, that displays a selection of modules to assist a user in learning patient Care protocols, the modules being selectable by the user for providing different interactive training sessions involving the protocols;

a physiological simulator for receiving simulated patient care activity responsive to the sessions;

a plurality of different virtual instruments for use with the simulator in performing the patient care activity, the virtual instruments cooperating with one or more sensors that interface with the computer program for providing feedback to the program regarding the activity during the sessions, such that in providing the feedback, the sensors confirm proper use of the virtual instruments on the simulator; and

an interface module for interfacing the sensors with the computer program, the interface module comprising lines each coupled with one of the sensors and a processor coupled with the sensor lines for receiving signals from the sensors and converting the signals to inputs for the computer program;

wherein each of said virtual instruments is different and is selected from the group consisting of an IV needle, an endotracheal ("ET") tube, an electrocardiogram ("EKG") monitor, a blood pressure ("BP") cuff, a pulse oximeter finger cuff, a temporary external pacer, an automatic external defibrillator ("AED") and manual defibrillators; and

wherein said interface module comprises a plurality of ports, wherein each of said ports is different and is selected from the group consisting of an intravenous/endotracheal ("IV/ET") port, a ventilation port, a compression port, an EKG port, a blood pressure, pulse oximeter, heartrate ("BP/O_SAT /HEARTRATE") port, a temporary external pacer port, an AED port, and manual defibrillator ports.

15. The system of claim 14 wherein the sensors are connected to one or both of the instruments and the simulator.

16. A kit for providing an interactive system for teaching patient care, comprising:

a computer program, for execution on a computer, that displays a selection of modules to assist a user in learning patient care protocols, the modules being selectable by the user for providing different interactive training sessions involving the protocols;

a physiological simulator for receiving simulated patient care activity responsive to the sessions;

at least two virtual instruments for use with the simulator in performing the patient care activity, the virtual instruments cooperating with sensors that interface with the computer program for providing feedback to the program regarding the activity during the sessions, such that in providing the feedback, the sensors confirm proper use of the virtual instruments on the simulator; and
