Simulation Devices

Product Development // Design // Engineering

The reusable arm was designed for IV insertion simulation. Balloons filled with simulated blood and a thin layer of silicone skin complete the model. Permanent channels in the arm hold the balloons in two different shapes while eliminating the need for an expensive refill cartridge. Tying a tourniquet around the arm reproduces the realistic effect of vein protrusion, and a small white pad elevates one end of the arm, allowing blood to flow into the IV without a pump.

The abdominal wound simulator demonstrates a median incision wound, a traverse public incision wound, and an ostomy reversal wound. The median incision wound is cut around the umbilicus. It is irregularly shaped, up to 5 cm deep in the subcutaneous fat layer, and yellow to pink in color.  The transverse public wound is below the umbilicus. This wound is 3-5 cm deep with muscle at the base and fat along the sidewalls. The ostomy reversal wound is round, red, to the left of the umbilicus, and over 3 cm deep. This simulator allows students to practice more advanced wound care techniques, such negative pressure wound therapy.

The breast models can be used to train medical students to perform clinical breast examinations, as well as biopsy and ultrasound techniques. Each model is formed from a different material to simulate natural variations in breast density.  Various objects inside the models imitate fatty, fibrous tissue often found in healthy breasts as well as fluid filled cysts and solids that can be more problematic.

The lower leg wound model is designed to teach physical therapy students to visually assess venous insufficiency, chronic venous stasis, and venous wounds. Students use this model to practice assessing, measuring, packing, and dressing wounds. The wounds vary in shape and size and have a realistic wet appearance.  This leg displays significant hemosiderin staining with thickened, dry skin.

Hands

Life Casting // Hot Plastic molding // Replication

The hands were replicated using life casting and mold making techniques. Models' hands were cast in different positions to create the uniquely shaped hooks. A “master hand” was created from each life cast, and a reusable silicone mold was created from the master.  Each mold can be replicated hundreds of times and filled with materials such as urethane rubber, flexible silicone, foam, plaster, or hard plastic of any color. The hands can be used as coat hooks, jewelry holders, or wall art.

Feet

Life Casting // Silicone molding // Replication

These feet were created using the most lifelike platinum cured silicone available to ensure a perfect replica of the model's foot. They can be displayed in any position with or without shoes, and the most recent models feature "bones" to provide structure.
