Spatial orientation determination in portable clinical analysis systems

摘要

The present invention covers the integration and utility of accelerometer features into a clinical analysis system. For example, measurement of dynamic acceleration and orientation of a blood-testing instrument with respect to Earth's gravitational field may be used to determine reliability of a test procedure and optionally to provide corrective elements thereof.

主权项

1. A portable clinical system for in vitro analysis, the system comprising:
a test device; and an analyzer comprising:
a processor, a computer readable memory, and a non-transitory computer readable storage medium;a port configured to receive the test device;program instructions to initiate performance of a test cycle of the test device in order to perform an analytical test;program instructions to determine a spatial orientation of the analyzer during the performance of the test cycle;program instructions to compare the determined spatial orientation to a threshold operating spatial plane for the test device;program instructions to provide an alert that at least one of instructs and illustrates corrective action including required movement of the analyzer to bring the spatial orientation of the analyzer within the threshold operating spatial plane for the test device in order to prompt a user to take the corrective action for the test device during the test cycle, when the determined spatial orientation exceeds the threshold operating spatial plane; andprogram instructions to receive the corrective action for the test device prior to the test cycle ending with a determination of a result of the analytical test, wherein the program instructions are stored on the non-transitory computer readable storage medium for execution by the processor via the computer readable memory.
