A patient simulator assembly for teaching patient care, the simulator assembly comprising: a patient simulator comprising: a patient body comprising one or more simulated body portions; a pair of bladders positioned within the patient body for simulating a patient's lungs; a compressor positioned within the patient body, the compressor in communication with the bladders for selectively providing an air supply to the bladders to simulate a respiratory pattern; a master module positioned within the patient body and configured for communication with an external control system; a respiratory module system positioned within the patient body and spaced from the master module, the respiratory module system controlling the respiratory pattern of the patient simulator by controlling the air supply to and from the bladders; and a delivery mechanism module for controlling the position of a fetal simulator within the patient body; wherein the patient simulator is operable without physical connection to an external device; a fetal simulator; a first module positioned on the delivery mechanism; and a second module positioned within a portion of the fetal simulator; characterised in that the first module and the second module are configured to provide positional data relating to the rotation of the fetal simulator relative to the patient body. a patient simulator comprising: a patient body comprising one or more simulated body portions; a pair of bladders positioned within the patient body for simulating a patient's lungs; a compressor positioned within the patient body, the compressor in communication with the bladders for selectively providing an air supply to the bladders to simulate a respiratory pattern; a master module positioned within the patient body and configured for communication with an external control system; a respiratory module system positioned within the patient body and spaced from the master module, the respiratory module system controlling the respiratory pattern of the patient simulator by controlling the air supply to and from the bladders; and a delivery mechanism module for controlling the position of a fetal simulator within the patient body; wherein the patient simulator is operable without physical connection to an external device; a patient body comprising one or more simulated body portions; a pair of bladders positioned within the patient body for simulating a patient's lungs; a compressor positioned within the patient body, the compressor in communication with the bladders for selectively providing an air supply to the bladders to simulate a respiratory pattern; a master module positioned within the patient body and configured for communication with an external control system; a respiratory module system positioned within the patient body and spaced from the master module, the respiratory module system controlling the respiratory pattern of the patient simulator by controlling the air supply to and from the bladders; and a delivery mechanism module for controlling the position of a fetal simulator within the patient body; wherein the patient simulator is operable without physical connection to an external device; a fetal simulator; a first module positioned on the delivery mechanism; and a second module positioned within a portion of the fetal simulator; characterised in that the first module and the second module are configured to provide positional data relating to the rotation of the fetal simulator relative to the patient body.
