Abstract
Systems and methods are presented herein for detecting different engagement conditions of a separator instrument of a system. Processing circuitry is used to establish a baseline of one or more operational parameters for the separator instrument. At least one deviation from the established one or more baseline operational parameters of the separator instrument is identified using the processing circuitry. The processing circuitry is used to determine that the identified at least one deviation corresponds to at least one engagement condition of the separator instrument. An action is caused to be performed based on the determining by the processing circuitry.

A method comprising:
- retrieving, using processing circuitry, a data structure comprising at least one stored predefined range of at least one operational parameter, wherein the at least one stored predefined range characterizes healthy blood;
- identifying, using the processing circuitry, a current operating state of a separator system;
- selecting, using the processing circuitry, a baseline value for the at least one operational parameter based at least in part on the current operating state of the separator system and the at least one stored predefined range of the at least one operational parameter;
- modifying, using the processing circuitry, operation of the separator system while maintaining the baseline value, wherein the modifying comprises one or more of:
- increasing a target value of the at least one operational parameter, or
- decreasing the target value of the at least one operational parameter;
- determining, using the processing circuitry, the separator system achieved at least one engagement condition during operation of the separator system;
- and
- causing, using the processing circuitry, an action to be performed by the separator system based on the determining.
A method comprising:
- receiving, using processing circuitry, a signal comprising real-time torque information for a motorized separator of a separator system;
- calculating, using the processing circuitry, a baseline torque value from the signal in real-time, wherein the baseline torque value corresponds to healthy blood that is without one or more of clots or occlusions;
- identifying, using the processing circuitry, at least one deviation from the baseline torque value in the signal;
- determining, using the processing circuitry, the at least one deviation corresponds to at least one engagement condition of the motorized separator of the separator system;
- and
- causing, using the processing circuitry, an action to be performed based on the determining.
