Definitions

  • the invention relates to a manikin able to simulate cardiac pathologies and usable for the training of cardiologists.
  • manikins have been constructed incorporating some resemblance to the trunk, the arms and the head of an actual person. These manikins house sensors and transducers which, for the principal points of the manikin, enable sounds and movements characteristic of the most diverse and typical pathologies for these points to be generated. The sounds can be detected by a stethoscope, the movements being detected either by direct observation or by palpitation.
  • US-A-3,662,076 describes a series of cams driven continuously always in the same direction by a variable speed electric motor, these cams comprising pumps which transmit an oscillatory movement to pistons positioned below and in contact with an elastic membrane simulating the manikin's skin;
  • US-A-4,601 ,665 describes a system in which the pistons positioned below and in contact with the manikin's "skin" consist of the rods of electromechanical transducers in which the same rods form part of a permanent magnet or a ferromagnetic material able to traverse telescopically within the cavity of a solenoid through which an electric current fed by the control system for this device flows;
  • GB-A-2,193,029 describes a manikin construction in which different constituent parts of the chest of the manikin are mounted on pins on which they can be made to rock between two positions by electromagnetic attraction.
  • the main object of the present invention is to provide a manikin for cardiac pathology simulation, which is able to transmit to selected zones of the manikin's "skin" mechanical oscillations of frequency and especially amplitude variable between a minimum and a maximum compatible with the pathology to be simulated.
  • a further object is to provide a manikin of the aforesaid type which is of simple and economical construction and of reliable pt. ra t ion .
  • a manikin comprising a profiled shell externally covered by an elastic membrane and internally housing at least one electromechanical transducer acting on a limited zone of said membrane to transmit pulsations thereto consequent on electrical pulses fed to said transducer by a computerized generator, characterised in that said electromechanical transducer consists of a cam carried by an electric motor rotatable in one direction and in the other direction to cause said cam to undergo rotations of up to 360° in amplitude.
  • said motor is an induction motor with a static frequency converter which feeds the motor with a sinusoidal voltage of adjustable amplitude and frequency.
  • Figure 1 is a schematic view from above showing the manikin covered by the elastic membrane simulating a patient's "skin".
  • Figure 2 is a longitudinal section through the manikin;
  • Figure 3 is a cross-section through the manikin on the line 3-3 of Figure 2.
  • the manikin shown schematically in the drawings comprises a profiled shell (constructed for example of aluminium, sheet steel or synthetic material) 1 simulating a human thorax and covered externally by an elastic membrane 2 simulating the human skin.
  • Apertures are provided in the shell in correspondence with zones in which it is desired to observe movements typical of certain cardiac pathologies. For simplicity, only one of these apertures is shown on the drawing, positioned in correspondence with the diaphragm and housing a movable plate 3, but further apertures can evidently be provided, for example in correspondence with the ictus.
  • a geared motor 4 on the output shaft of which there is keyed a cam 5.
  • the motor is constructed such as to be able to transmit to the relative cam a rotation in one direction or the other, at a variable frequency and with a variable angle of rotation which, in the illustrated example, has a maximum amplitude of 180 °.
  • the motor 4 is preferably of the single phase or three phase induction type, with a static frequency converter which, by means of an inverter circuit of pulse width modulation type, provides the motor with a sinusoidal voltage of adjustable amplitude and frequency, this not being described herein for simplicity and because it is of known type easily implemented by a normal expert of the art.
  • the shape or contour of the cam either causes the diaphragm to rise to its maximum extent or causes it to rise to a predetermined extent (less than the maximum).
  • the diaphragm can b raised and lowered to t e extent and with the frequency typical of the pathology to be simulated.
  • the elastic membrane 2 acts as a spring for maintaining the plate 3 pressed against the cam surface.
  • Constructional modifications can be adopted aimed at limiting the friction and wear between the cam and plate.
  • the cam can be housed within the inner cage of a rolling bearing, the outer cage of which is fixed to the movable plate.
  • between the plate and cam there can be interposed an intermediate element with springs which maintain the plate always urged towards the cam surface.
