Abstract

A medical training apparatus comprising an instrument holder with a medical instrument, a model patient body simulating a patient subject to medical treatment or examination, and an examination table on which the model patient body is placed. The medical training apparatus comprises a posture detection means for detecting the posture of the examination table, a medical instrument status detection means for detecting the working status of the medical instrument, an examination receiving status detection means for detecting the situation of the model patient body in medical treatment or examination, and a model patient body driving means housed in the model patient body. The model patient body driving means changes the facial or body expression of the model patient body, depending on combination of at least one of the posture detection signal output from the posture detection means and the medical instrument status detection signal output from the medical instrument status detection means, and the examination receiving status detection signal output from the examination receiving status detection means.

said model patient body driving means is controlled and driven by operating said model patient body control/operation means so as to perform the expressions selected by said expression selection means.

6. The medical training apparatus as set forth in claim 1 or 3, wherein said examination table comprises a sitting seat movable up and down, a tiltable back seat connected to the rear end of said sitting seat, and a tiltable headrest connected to the upper end of said back seat.

7. The medical training apparatus as set forth in claim 1 or 3, wherein said model patient body is connected to at least one of an electric driving system and a fluid driving system relative to said examination table.

8. The medical training apparatus as set forth in claim 1 or 3, wherein said model patient body has a head model with eyes, a nose and a mouth cavity and said mouth cavity has a jaw model.

9. The medical training apparatus as set forth in claim 8, wherein said model patient body driving means drives at least one of the eyes, eyelids, jaw and neck provided in said model patient body.

10. The medical training apparatus as set forth in claim 1 or 3, wherein said medical instrument status detection means detects at least one of the following factors:

the voltage or the current value corresponding to the rotation number of the medical instrument;

the air pressure, the air flow amount, the frequency, the vibration number of said instrument when operated;

the suppress strength to an affected part of said model patient body;

the detection signal of picking up said medical instrument from said instrument holder;

the operation signal of a foot controller connected to said examination table; and

the operation signal of an operation means provided in said medical instrument.

11. The medical training apparatus as set forth in claim 6, wherein said posture detection means detects at least one of the elevating position of said sitting seat, the tilting angle of said back seat, and the tilting angle of said headrest.

12. The medical training apparatus as set forth in claim 8, wherein said examination receiving status detection means has at least one of a contact sensor provided for a cheek member of said head model, and a temperature sensor, a contact sensor, an angle sensor, a pressure sensor, a conduction sensor, a vibration sensor, and an impact sensor provided for said jaw model.

13. The medical training apparatus as set forth in claim 1 or 3, wherein an imaging means is further provided for photographying the medical treatment or examination status of said model patient body.

14. The medical training apparatus as set forth in claim 1 or 3, wherein said model patient body has an audio output means for outputting a predetermined voice in response to said examination receiving status detection signal.

15. The medical training apparatus as set forth in claim 1 or 3, wherein said model patient body is so constructed as to be detachably placed on said examination table via a coupling means.

16. The medical training apparatus as set forth in claim 15, wherein said model patient body has a driving system connecting portion in said model patient body driving means side, said connecting portion being detachable to at least one of a connecting portion of an electric driving system and a connecting portion of a fluid driving system provided in said examination table when coupled via said coupling means.
