Efficiently scaled to approximate the thigh region with a combination of a knife wound and with both entry and exit wounds of a 9 mm gun round. The simulation presents significant tissue loss that is expected in an aggressive assault environment that will require quick rescue intervention. The simulator can be used with QuickClot Haemostatic dressings or related products to address large irregular wounds and the risks associated with large blood loss. The unit gives focused training on rapid packing and then later unpacking deep complex wounds. A cost effective training solution for those working in environments where knife and gun wounds will be encountered.
