Abstract

A manikin and control system is provided for use by a student practicing a procedure usually applied to the human body, such as cardiopulmonary resuscitation. The system includes a manikin that has an artificial lung into which the student can blow to expand the lung, and a resilient chest which the student can compress. Sensors are provided in the manikin to accurately detect the instantaneous amount of lung expansion and chest compression. An A/D converter converts the sensor signals to digital signals and inputs them to a compact controller based on an inexpensive microcomputer chip which also stores the control program in ROM. Pushbuttons on the controller'"'"'s front panel enable the student to select any one of a variety of teaching routines prestored in the microcomputer'"'"'s ROM. The microcomputer then uses lamps on the panel and a speech synthesizer having prerecorded human speech stored in external ROM chips to issue instructions and advice to the student. These are contingent on his performance of the selected routine as detected by the sensors. However, a prestored interrupt routine always enables the student to switch from the current routine to any other, or to get an immediate repeat of the last message from the system. Transducers are provided for simulating a carotid pulse and shallow breathing in the manikin, and these can be activated by an instructor via remote control using a wireless transmitter and receiver pair.

Claims

1. A chest compression training device comprising:

means for simulating a compressible chest of a patient ad including a correct hand position area for chest compression;

means for detecting the existence and direction of an error in hand position committed by a student employing said training device;

and a read-out comprising correct hand position indicium means for indicating the location of said correct hand position area, a plurality of hand position error indicator means arranged in a ring surrounding said correct hand position indicium means, and means responsive to the detection of a hand position error by said detecting means to activate whichever of said hand position error indicator means represent the direction of said detected hand position error in relation to said correct hand position indicium means.
