1. An eye assembly, comprising:
- a simulated eyeball including an iris movable between a first position and a second position to simulate pupil dilation, wherein the first position has a first diameter and the second position has a second diameter, the second diameter being greater than the first diameter; and
an eyelid assembly coupled to the simulated eyeball, wherein the eyelid assembly is configured to simulate blinking, the eyelid assembly comprising;
an eyelid moveable between an open position and a closed position; and
a pneumatic blinking actuator in communication with the eyelid, wherein the pneumatic blinking actuator is configured to move the eyelid between the open and closed positions to simulate blinking of the eye, the pneumatic blinking actuator comprising;
a plate coupled to the eyelid such that movement of the plate causes movement of the eyelid;
an air supply;
an opening bag in communication with the air supply and configured to urge the eyelid towards the open position by moving the plate away from the eyelid upon inflation; and
a closing bag in communication with the air supply and configured to urge the eyelid towards the closed position by moving the plate towards the eyelid upon inflation.

Abstract
An eye assembly for use in a patient simulator is provided. The eye assembly includes an iris diaphragm having a moveable inner portion defining an opening. The inner portion of the iris diaphragm is movable radially from a first position wherein the opening has a first diameter and a second position wherein the opening has a second diameter greater than the first diameter. The iris diaphragm is configured for use in a simulated eye. The eye assembly also includes a dilation actuator in communication with the inner portion of the iris diaphragm for selectively moving the inner portion between the first and second positions to simulate dilation of an eye.

3. An eye assembly for use in a patient simulator, the eye assembly comprising:
-
an iris diaphragm having a moveable inner portion defining an opening, the inner portion movable radially between a first position wherein the opening has a first diameter and a second position wherein the opening has a second diameter, the second diameter being greater than the first diameter; a dilation actuator in communication with the inner portion of the iris diaphragm, the dilation actuator configured to selectively move the inner portion between the first and second positions to simulate dilation of an eye; and an eyelid assembly positioned proximate to the iris diaphragm, wherein the eyelid assembly is configured to simulate blinking, the eyelid assembly comprising; an eyelid moveable between an open position and a closed position; an intermediate member coupled to the eyelid such that movement of the intermediate member causes movement of the eyelid; and a blinking actuator in communication with the eyelid, the blinking actuator configured to move the eyelid between the open and closed positions to simulate blinking of the eye by selectively moving the intermediate member; wherein the dilation actuator and the blinking actuator are configured to be in communication with a control module of the patient simulator, and wherein the dilation actuator and the blinking actuator are configured to execute commands received from the control module relating to the simulated dilation and blinking; wherein the blinking actuator comprises a pneumatic system, wherein the pneumatic system comprises; an opening bag configured to urge the eyelid towards the open position upon inflation by moving the intermediate member away from the eyelid; a closing bag configured to urge the eyelid towards the closed position upon inflation by moving the intermediate member towards the eyelid; and an air supply in communication with the opening and closing bags. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 17, 18)
