Constructing the torso

Shaped wooden base

a flat piece of wood has been cut to shape. Holes have been drilled and commercial electrical wire passed through. Yanker suckers put over the wires form the ribs. The upper portion of the sternum has the been added as two small slices of wood stuck together with a small hole left to insert and fix the lower removable half of the sternum that will be cut through during the simulations.

The lower half of the board is covered with cushion foam and then topped with cheap coloured vinyl off ends to form an abdomen

The subcutaneous layers

The intercostal muscles, fat and skin are then built up using foam, latex and silicone. We found expanding building foam really useful. The construction replicates the flexibility of the thorasic wall so it can open up in the clam shell.

Some plumbing

Two tubes join from the shoulder to make the circulatory system for the heart. An access pipe allows blood to be transfused in the system during the resuscitation. One way valves are needed to stop the heart from overfilling from the pressure of the transfusion fluid flowing directly into the heart. 

Give it some air

The trachea is made of old ventilation tubing connected to a T piece to allow our lungs to be attached on either side. 

The thoracic cassette

Note that some of the Yanker suckers have been left open ended. This allows our replaceable section of the thorax to be plugged in. Yep you guessed it more Yanker sucker ribs lock into these. The lower sternum is made from a wooden tongue depressor and some plaster. half of the tongue depressor locks into the hole of the upper half of the sternum to give three point fixation. A cheap muscle vest fancy dress item makes up the skin and is glued to the removable rib section. We also attached velcro to stick down the edges.
