Abstract

An interactive education system for teaching patient care to a user is described. The system comprises a patient simulator; a virtual instrument for use with the patient simulator in performing patient care activities; means for sensing an interaction between the virtual instrument and the simulator, and means for providing feedback to the user regarding the interaction between the virtual instrument and the simulator.

Claims

1. An interactive education system for teaching patient care to a user, the system comprising:

a computer having a program for displaying a selection of selectable modules for providing different interactive training sessions;

a patient simulator operably connected to the computer;

a virtual instrument for use with the simulator in performing patient care activities;

a sensor for sensing an interaction between the virtual instrument and the simulator, wherein the sensor is disposed on a skin overlay which is removably attached to the patient simulator; and

means for providing feedback to the user regarding the interaction between the virtual instrument and the simulator.

2. The system of claim 1 herein the means for providing feedback to the user regarding the interaction between the virtual instrument and the simulator is a microcontroller.

3. The system of claim 1 wherein the means for providing feedback to the user regarding the interaction between the virtual instrument and simulator is a computer program.

4. The system of claim 1 wherein the virtual instrument is selected from a group consisting of at least one IV needle, an ET tube, an ECG monitor, a BP cuff, a pulse oximeter cuff, a temporary external pacer, an AED, a manual defibrillator, ultrasound wand, a virtual stethoscope, a thermometer, and a fetal distress monitor.

5. The system of claim 1 wherein the interaction is between an acquisition coil of the virtual instrument and a COB module of the sensor.

6. The system of claim 1 wherein at least one of the modules provides controls for the patient simulator to respond to patient care activity.

7. The system of claim 1 wherein the feedback is provided as an audible presentation of sounds.

8. The system of claim 1 wherein the simulator represents an adult patient.

9. The system of claim 1 wherein the simulator represents a non-adult patient.

10. The system of claim 1 wherein the simulator represents a portion of a patient.

11. The system of claim 1 wherein the simulator changes color to represent changes in oxygenation.

12. The system of claim 11 wherein the computer program directs the changes in oxygenation for the simulator.

13. The system of claim 12 wherein the changes in oxygenation for the simulator simulate the patient improving, worsening, or remaining the same.

14. The system of claim 11 wherein the changes in oxygenation for the simulator are in response to CPR quality performed by the user.

15. The system of claim 11 wherein the changes in oxygenation for the simulator simulate the patient improving, worsening, or remaining the same in response to CPR quality performed by the user.

16. A patient simulator for receiving simulated patient care activity comprising:

a maternal portion;

a fetal portion disposed in the maternal portion; and

means for automatically delivering the fetal portion from the maternal portion to simulate child birth, wherein the means for automatically delivering the fetal portion from the maternal portion to simulate child birth include;

(i) a track disposed within the maternal portion; and

(ii) a ram attachable to the fetal portion for moving the fetal portion down the track.

17. The simulator of claim 16 wherein the ram translates the fetal portion out of the maternal portion.

18. The simulator of claim 17 wherein the ram includes a projection for producing rotational movement of the fetal portion.

20. The simulator of claim 16 wherein the ram produces internal and external rotational movement of the fetal portion, relative to the maternal portion.

21. The simulator of claim 16 wherein the ram is driven by a hand crank.

22. The simulator of claim 16 wherein the ram is driven by a motor.

23. The simulator of claim 22 wherein the motor is controlled by a control box.

24. The simulator of claim 22 wherein the motor is controlled by software.

33. The simulator of claim 16 further comprising a distensible cervix for placing in the maternal portion.

34. The simulator of claim 33 wherein the distensible cervix comprises a ring, and a wall connected to the ring, wherein the wall is of an elastic material, and wherein the wall has a central gathering that defines a port.

35. The simulator of claim 34 wherein the gathering has an associated elastomeric element disposed interiorly to enhance the elasticity of the port.

36. The simulator of claim 33 wherein the port expands from two to ten centimeters in diameter as the fetal portion is pushed through the port.

37. The simulator of claim 33 wherein the shape of the head of the fetal portion causes expansion of the cervix to correlate to fetal descent.

38. The simulator of claim 33 further comprising reversible fastening means to hold the ring in the maternal portion.

19. The simulator of clair 17 wherein the ram has at least one lever for engaging a cam disposed on the track to produce rotation of the fetal portion during translation.

25. A child birthing device for automatically delivering a fetal manikin from a Amaternal manikin to simulate child birth, comprising:

a track for disposed within the maternal manikin; and

a ram attachable to the fetal manikin for moving the fetal manikin down the track.

26. The device of claim 25 wherein the ram translates the fetal manikin out of the maternal manikin.

27. The device of claim 25 wherein the ram includes a projection for producing rotational movement of the fetal manikin during translation.

28. The device of claim 25 wherein the ram produces internal and external rotational movement of the fetal portion, relative to the maternal portion.

29. The device of claim 25 wherein the ram is driven by a hand crank.

30. The device of claim 25 wherein the ram is driven by a motor.

31. The device of claim 30 wherein the motor is controlled by a control box.

32. The device of claim 30 herein the motor is controlled by software.

39. A patient simulator for receiving simulated patient care activity comprising:

a central portion;

a peripheral portion disposed radially distant from the central portion; and

means for independently changing the color of the central portion and peripheral portion to simulate cyanosis of the simulator.

40. The simulator of claim 39 wherein the means are logically linked to ventilation of the patient simulator.

41. The simulator of claim 39 wherein the means are controlled by a user.

42. The simulator of claim 39 wherein the means for independently changing the color of the central portion and peripheral portion to simulate cyanosis of the simulator comprise:

(i) a thermochromatic dye dispersed into clear vinyl paint and applied to the central portion and the peripheral portion; and

(ii) at least one resistance heater disposed in the central portion, and at least one resistance heater disposed in the peripheral portion to provide heat energy, thereby causing the color to disappear.

43. The simulator of claim 42 wherein the at least one resistance heater disposed in the central portion and at least one resistance heater disposed in the peripheral portion have separate controls.

44. The simulator of claim 42 further comprising at least one heat sink to allow for faster return of coloration.
