摘要:
Maternal and fetal birthing simulators are disclosed. The maternal simulator has a rotatable pelvis, legs articulated at the hip and knee joints, and a deformable covering that simulates the feel of the skin and underlying tissues. The fetal simulator has an extensible neck, a movable head, movable clavicles, and arms articulated at the shoulder and elbow joints, and may include sensors to measure spinal extension, head rotation, applied traction force, and brachial plexus displacement.

Maternal and fetal birthing simulators are disclosed. The maternal simulator has a rotatable pelvis, legs articulated at the hip and knee joints, and a deformable covering that simulates the feel of the skin and underlying tissues. The maternal birthing simulator may optionally be used with a pressure-based uterine propulsive system. The fetal simulator has an extensible spine, a movable head, movable clavicles, and arms articulated at the shoulder and elbow joints, and may include sensors to measure spinal extension, head rotation, applied traction force, and brachial plexus displacement. Fetal brachial plexus strain simulators and simulation methods are also disclosed.
摘要:
A brachial plexus simulator is disclosed. The brachial plexus simulator comprises a head, a spinal assembly, and a simulated brachial plexus. The head may be weighted to a biofidelic weight and may include a tilt sensor. The spinal assembly comprises a simulated spine mounted for extension. The simulated brachial plexus comprises a network of nerve tubing that is attached relative to the simulated spine at appropriate points so as to mimic the connectivity, shape, and compliance of the brachial plexus. The nerve tubing may be filled with a fluid material whose resistance or other electrical properties change with its length, such as mercury. Maternal and fetal birthing simulators are also disclosed.
