INSTRUCTIONS TO BE ALLOWED

CAREFULLY:

  1. Handle with care
  2. Do not place the model upside down.
  3. Cut off the power supply immediately after the performance; the model will be Deformed at an extended high temperature.
  4. After the performance, turn the crank till the atria, the ventricles, and Other Parts of the model returning to a relaxed state; thus preventing their Deformation.
  5. In case the lamps are not lighted, cut off the power supply, and replace them with screw-based miniature lamps(220 15W).

FUNCTIONING HUMAN HEART AND CIRCULATORY SYSTEM MODEL

USES:

This especially model is excellent for teaching in Anatomy and Physiology In secondary schools, university departments of biology, medical secondary Schools, and medical colleges. It is made to help the students have a clearer The conception of the internal structure of a human heart, the cardiac cycle, and the Overall plan of the systemic and the pulmonary circulatory system.

PERFORMANCES:

The model is sectioned to demonstrate the pumping action of the heart during

An entire cardiac cycle and circulation through the systemic and pulmonary

Circuits.

  1. With the principles of mechanical kinetics being applied, the model is

Made to demonstrate the sequence of events that occurs during one heartbeat

And subsequent relaxation.

  1. Systemic and pulmonary circulation and flowing of blood through a

A continuous network of blood vessels is demonstrated by means of lightening

Of a sequence of miniature lamps in succession.

OPERATING INSTRUCTION:

  1. Connect the model to the power supply (22V AC).
  2. 2. Insert the crank (included) in the hole on the back of the model, and tum

It counterclockwise gradually. When the crank is turned about 1/3 round, the

The model begins to work. The sequence of events that occurs during one heartbeat

And subsequent relaxation happens as follows.

  1. The atria squeeze together, pumping blood into the ventricles. Valves Between the atria and the ventricles are open, allowing blood to easily pass Through.
  2. ِWhen the ventricles contract, the atria are relaxed. The atrioventricular (AV) valves close, so that blood does not flow back into the atria.
  3. The semilunar valves are open, the ventricles send blood into great Arteries.
  4. When the ventricles relax, the semilunar valves close, preventing Backflow into the ventricles.
  5. Valves between the atria and the ventricles are open and blood again Enters the ventria. The entire pattern of pumping begins again. To demonstrate the exchange of gases as blood circulating through the Pulmonary capillary network by means of flashing of the miniature lamps Concerned, tum on and off the switch on the lower part of the front of the base (In the shape of a box).
