Abstract
A manikin and control system is provided for use by a student practicing a procedure normally 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.
