Device and method for sampling and analysing body fluids

摘要

The single-use sampling and sensor unit (2) for the body fluids sampling device has a microneedle (3) attached to the center of the flexible membrane (4). The single-use sampling unit has a flat base (14) which is placed against the patient's body. The microneedle pierces through the base into the patient's skin. A chemical sensor unit (5) is situated in the channel leading past the needle to the space under the membrane. The sampling unit is snapped into place in a handle (1) containing a spring-loaded (6) air compressor piston (8) a measurement device (10) and a display (12). The piston is released by a catch (7) and compresses air to push the membrane inward.
