In a system and a method of testing a person in the performance of cardiopulmonary resuscitation and for evaluating training exercises therein, a training device simulating a patient includes sensors for detecting various resuscitation procedures performed thereon. Parameter signals from the sensors are fed to a computer including a series of counters, a timing means and various memories, for analyzing the parameter signals and assessing whether the corresponding operations have been correctly or incorrectly performed. The values processed by the computer are then displayed on a display providing a clear moving representation of the procedures performed on the training device, the representation taking place in real time on the basis of corresponding signals from the timing means, whereby, by viewing the display, the trainee operator can directly check and if appropriate correct the resuscitation procedures he is performing. The display can display the whole of the cardiopulmonary resuscitation operation including preparatory procedures.
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.
The invention is directed to a fault triggering component for life-sustaining systems such as ventilating apparatus and anesthesia apparatus. The fault triggering unit is adapted so as to be connectable to or exchangeable with one of the standard plug-in components of the system. The fault triggering unit includes at least one remote-controllable drive member and this drive member is connected to a movable triggering component which triggers at least one fault with its movement. A circuit arrangement for assembling a training program for a ventilating apparatus having a lung simulator is also disclosed.
Apparatus for teaching respiratory auscultation semiology includes a manikin, a stethoscope simulator having a head and earpieces connected to a receiver and a control device connected to the manikin. The manikin has an envelope animated by a drive system and proximity sensors responsive to the head. The control device includes a control unit, a memory for groups of sound data associated with a respiratory condition connected to it to supply the data to it, and a transmitter connected to it to receive a sound data signal derived from this data. The control unit is connected to the manikin to receive signals from the sensors and, according to their source, to produce the sound data signal and a motor control signal derived from the sound data.
The present invention relates to a training device for teaching emergency aid techniques for a person in an emergency situation, wherein said device comprises a model (1) of a human being that includes the following units connected together so as to be capable of movement: a head unit (2) provided with a device (10) for protecting students against cross-contamination: a neck unit (3); and a trunk unit (4) with upper (5) and lower (6) extremities. Said training device also includes a control system for the teaching process in the form of an anatomic display (7) that comprises video simulators for the internal organs of a human being and for traumas to said internal organs, wherein said simulators are connected to a computer (9). The model (1) further includes a set of simulators for the vital activity of the inner organs of a human being and for the traumas thereto, wherein said simulators are provided with sensors for detecting external actions applied thereon.
A cardio-pulmonary resuscitation (CPR) aid is disclosed. It is in the form of a wrist watch (10) having a set of auxiliary push buttons (13, 14 and 15). When a push button (13, 14 or 15) is pressed, audible signals are emitted from a beeper (16) at a rate dependent on which of the push buttons (13, 14 or 15) is pressed for use in timing external heart massage. The appropriate one of a set of push button lights (23, 24 or 25) associated with respective ones of the push buttons (13, 14 or 15) flashes in synchronism with the audible signals for timing CPR in noisy areas. The watch also records the elapsed time since the initiation of the CPR signals and the number of timing signals produced.
