Physiological fluid extraction with rapid analysis

摘要

A device for sampling and analyzing a physiological fluid from the skin of a patient by puncture. The device includes a body and sensors. The body has a needle with a point for puncturing a physiological tissue and a channel in the body for conducting the physiological fluid away from the point. The sensors are located in the body and are accessible to the physiological fluid conducting along the channel for physiological fluid analysis. The device can be used to lance the skin and obtain a representative sample of the physiological fluid, with relatively simple procedures and quick analysis to minimize the exposure of the physiological fluid sample to air.
