Abstract: The present disclosure relates to a method and a device for predicting ability of a temporary plugging agent to plug cracks and a storage medium, and includes the following steps: calculating a plane elastic modulus of a core through experiments, acquiring a maximum force load of a specimen, calculating rock fracture toughness through the maximum force load, manufacturing an artificial crack model and placing it in a core holder, preparing temporary plugging deflection fluid by selecting a temporary plugging agent, injecting the temporary plugging deflection fluid into the artificial crack so as to calculate apparent fracture toughness of the temporarily plugged crack, and finally calculating a fracture pressure of the temporarily plugged crack based on the calculated rock fracture toughness and the plane elastic modulus of the core. Through the above method, the present disclosure provides a standard fracture pressure calculation method.

Abstract: An access instrument system that can identify tissue type and a bone fusion assessment system are disclosed. In one embodiment, the bone fusion assessment system includes a smart implant including: an implant body adapted to be affixed to a bone of a patient and to provide a therapeutic benefit thereto; and a bone fusion measurement system. The bone fusion measurement system includes a processing element; a sensor in electrical communication with the processing element and adapted to measure health data of the patient; and a wireless interface adapted to receive power and transmit the health data.
