Abstract

The apparatus includes a probe that has an area of linear contact with the skin of a mannequin along a longitudinal axis. The mannequin includes means for activation of a group of at least two sensors by the probe. The invention provides for at least two probe orientations. The apparatus further allows one to visualize deep organs with images of real clinical cases that are stored in a audio-visual memory.

Claims

1. Apparatus for simulation of a non-invasive medical examination of organs, comprising:

a mannikin (1) representing at least part of a human body, said mannikin (1) including a plurality of sensors;

signal generator means (4) for generating signals representative of a given physiological or physiopathological condition;

a system unit (2) controlling said signal generator means (4) in response to activation of said sensors;

scanning means (5) for scanning said mannikin, said scanning means for controlling operation of said signal generator means (4), characterized in that said scanning means (15) is a probe having an alignment plane;

said sensors are arranged in a plurality of groups, each group includes at least two of said sensors located on a respective common line, and a group of sensors is activated by said probe when the alignment plane of the probe contains a respective common line of that group.

2. Apparatus according to claim 1 wherein said sensors are arranged in a plane.

3. Apparatus according to claim 2 characterized in that each group of at least two sensors is associated with a set of signals representative of the physiological or physiopathological condition.

4. Apparatus according to claim 2 characterized in that the probe (5) includes at least one magnet adapted to stimulate at least two sensors in a plane passing through an axis defined by the two sensors.

5. Apparatus according to claim 4 wherein each said group of sensors is associated with a set of signals representative of the physiological or physiopathological condition.

6. Apparatus according to claim 5 characterized in that the signals representative of the physiological or physiopathological condition comprise audiovisual data stored in memory means and corresponding, for a given condition, to each possible position of the probe (5) on the mannikin (1).

7. Apparatus according to claim 6 characterized in that the memory means comprise at least one videodisk or CD-I player.

8. Apparatus according to claim 6 wherein said signal generator means comprise a TV monitor and said system unit is operative to receive signals from sensors which are activated by said probe and to control reproduction of audiovisual data from the memory means on said TV monitor.

9. Apparatus according to claim 8 characterized in that the memory means comprise at least one videodisk or CD-I player.

10. Apparatus according to claim 1 wherein said probe comprises a magnet for activating at least two of said sensors when said alignment plane intersects the two sensors.

11. Apparatus according to claim 10 characterized in that each group of at least two sensors is associated with a set of signals representative of the physiological or physiopathological condition.

12. Apparatus according to claim 1 characterized in that the sensors are of the magnetoresistive type.

13. Apparatus according to claim 1 characterized in that the probe (5) includes a switch (8) for selecting either of two modes and in that a cable (9) connecting the probe (5) to the system unit (2) is used to transmit a signal representative of which mode is chosen.

14. Apparatus according to claim 1 characterized in that it includes manual means for selecting in the system unit a physiological or physiopathological condition to be simulated.

15. Apparatus according to claim 1 characterized by the association with a scanning area of the mannikin of an array of two sets of sensors disposed at different depths under the skin of the mannikin.

16. Apparatus according to claim 1 wherein at least one of said groups of sensors includes two of said sensors located on the respective common line and a third one of said sensors disposed at a location spaced from the common line so that the two of said sensors and said third one of said sensors lie in a common plane, and said sensors of said at least one said group are activated only when said probe is oriented so that the alignment plane coincides with the common plane.
