Abstract: Data representative of operation of biomedical equipment in a medical facility is collected and stored in a centralized database. The information may be collected manually during the life of the equipment, or automatically by connection to the equipment. The data references equipment types, manufacturer, departments, locations, and other relevant information for the equipment. Based upon the collected and stored information, parameters representative of possible training needs is analyzed and reported. The parameters may include error, breakdowns, and the like. Detailed reports delivered to the medical institution may thus provide a basis for planning training to enhance performance and utilization of the equipment.

Abstract: An intercalary implant has two stem members and a collar. One stem member includes a stem portion to be received in the intramedullary canal of a native end portion of a long bone and a threaded male portion to be outside of the intramedullary canal. The second stem member also includes a stem portion to be received in the intramedullary canal of the opposite native end portion of the long bone. The second stem member has a spacer portion and a shoulder to be outside of the intramedullary canal. The collar has an annular base portion with an opening and a cylindrical female threaded portion. When assembled, collar connects the first and second stem members and the implant spans a gap in the shaft of the long bone. The parts can be assembled without distracting the native end bone portions in the proximal-distal direction to prevent damage to soft tissue around the native end bone portions.
