Abstract: The illustrative embodiment is a simulation system for practicing vascular-access procedures without using human subjects. The simulator includes a data-processing system and a haptics interface device. The haptics device provides the physical interface at which an end effector (e.g., medical instrument, such as a needle, catheter, etc.) is manipulated to simulate needle insertion, etc. In accordance with the illustrative embodiment, the haptics device includes a receiver. The receiver receives the end effector when it's inserted by a user into the haptics device. Sensors that are associated with the receiver monitor the motion and position of the end effector, generate signals indicative thereof, and transmit the signals to the data processing system. The signals are processed to determine the effects of manipulation of the end effector.

Abstract: The illustrative embodiment is a simulation system that provides realistic training and practice for vascular-access procedures without using human subjects. The simulator includes a data-processing system and a haptics interface device. The haptics device provides the physical interface for performing vascular-access procedures by manipulating a needle/catheter module to simulate needle insertion, etc. Some embodiments of the system include a palpation module, a skin-stretch module, or both. The palpation module provides an ability to practice palpation and occlusion techniques, while the skin-stretch module provides an ability to practice a skin-stretch technique.
