Simulation model of human lower limb

摘要

An effective model for medical technology,Especially the simulation device,It can also be used for internal angiography in Medical College and secondary medical college students. PretenderThe ion model of human lower limbs is made of three-dimensional printing materials, with feet as the real size.The same person's organization as touch,The sound of it. Above the knee in the front, more than a third of the hip of the simulation model is an incision,Simulate a typical stock visit. The lower extremity vascular system,Simulating the river bed with blood vessels,It includes femoral artery and femoral vein,Through the tube,It's a closed system. Throughout the front of the lower extremity, from the upper third of the thigh to the thigh joint, there is a light-emitting diode that can visually detect the symptoms of blood clots. Blood vessels of lower limbs,In this case, blue LEDs simulate cyanosis,The red glow simulates congestion,Green light is used to create hues. On the outer surface of the tube,The femoral artery was simulated,The position of the electromagnet. The simulated artificial thrombus is composed of silicone and metal chips. In the management,It is a typical femoral artery,The position is a probe type input hole,Silicone headA contact detector was installed nearby to determine if Fogarty detector was introduced,Connected to the sensor,This is an incremental encoder,Probe penetration depth. Control unitPipe internalsSimulating the river bed with blood vessels,It is composed of micro controller,Pump drive,A set of electromagnet driver and wireless interface,In this case, the control unit is related to the actual insertion of the detector into the sensor,The probe and led penetrate the depth sensor through the wire. Technical achievements: achieve the goal through the proposed human lower limb simulation model;Provide internal angiography training.
