In some instances, a patient simulator system is provided that includes a maternal patient simulator and a fetal patient simulator. The maternal patient simulator includes an internal chamber sized to receive the fetal patient simulator and a birthing mechanism disposed within the internal chamber configured to translate and rotate the fetal patient simulator with respect to the maternal patient simulator to simulate a birth. In some instances, the fetal patient simulator an internal support structure that includes a head, spinal components, left arm components, right arm components, left leg components, and right leg components with a continuous silicon skin layer covering the internal support structure. ## Claims ### Claim 1 A patient simulator system, comprising: a fetal patient simulator having: an internal support structure that includes a head, spinal components, left arm components, right arm components, left leg components, and right leg components, wherein the internal support structure of the fetal patient simulator includes a plurality of openings for receiving a stiffening rod; and a continuous silicon skin layer covering the head, spinal components, left arm components, right arm components, left leg components, and right leg components of the internal support structure; and a maternal patient simulator having: an internal chamber sized to receive the fetal patient simulator; and a birthing mechanism disposed within the internal chamber, the birthing mechanism configured to translate and rotate the fetal patient simulator with respect to the maternal patient simulator to simulate a birth, wherein the birthing mechanism of the maternal patient simulator is configured to selectively engage a portion of the stiffening rod. ### Claim 2 (depends on 1) The patient simulator system of claim 1, wherein the spinal components of the internal support structure of the fetal simulator include a plurality of joints. ### Claim 3 (depends on 2) The patient simulator system of claim 2, wherein at least some of the plurality of joints include a motion encoder to detect a relative position of the joint. ### Claim 4 (depends on 1) The patient simulator system of claim 1, wherein the fetal patient simulator includes a force sensor for monitoring a force applied to the patient simulator. ### Claim 5 (depends on 1) The patient simulator system of claim 1, wherein the fetal patient simulator includes an actuator system for selectively raising the head of the fetal patient simulator. ### Claim 6 The patient simulator system of claim wherein the actuator system includes a motorized pulley system. ### Claim 7 (depends on 1) The patient simulator system of claim 1, wherein the stiffening rod provide structural integrity to the spinal components of the fetal simulator during the birth simulation. ### Claim 8 (depends on 1) The patient simulator system of claim 1, wherein the maternal patient simulator includes a removable tummy cover. ### Claim 9 (depends on 8) The patient simulator system of claim 8, wherein the removable tummy cover is configured to simulate at least one of maternal contractions and a fetal heart rate. ### Claim 10 (depends on 9) The patient simulator system of claim 9, wherein the removable tummy cover includes at least one speaker for simulating the fetal heart rate. ### Claim 11 (depends on 9) The patient simulator system of claim 9, wherein the removable tummy cover includes at least one reservoir configured to receive fluid or air, wherein selective introduction and removal of the fluid or air into the at least one reservoir simulates the maternal contractions. ### Claim 12 (depends on 1) The patient simulator system of claim 1, Wherein the maternal patient simulator includes articulating hip joints. ### Claim 13 (depends on 12) The patient simulator system of claim 12, wherein the articulating hip joints include a first plate secured to a torso of the maternal patient simulator, a second plate secured to a leg of the maternal patient simulator, and a flexible tubular member extending between the first and second plates. ### Claim 14 (depends on 13) The patient simulator system of claim 13, Wherein the articulating hip joints further include a plurality of tethers extending between the first and second plates to limit relative motion. ### Claim 15 (depends on 13) The patient simulator system of claim 13, wherein the articulating hip joints further includes a sensor for monitoring relative movement of the hip joint. ### Claim 16 (depends on 1) The patient simulator system of claim 1, further comprising the stiffening rod. ### Claim 17 (depends on 1) The patient simulator system of claim 1, wherein the fetal patient simulator farther includes a locking mechanism for fixedly engaging the stiffening rod. ### Claim 18 (depends on 17) The patient simulator system of claim 17, wherein the locking mechanism includes a spring-loaded mechanism configured to engage a structure of the stiffening rod. ### Claim 19 (depends on 17) The patient simulator system of claim 17, wherein the locking mechanism is electronically controllable to selectively fixedly engage the stiffening rod.
