DEVICE FOR BIOSENSING WITH INDWELLING VENOUS CATHETER

摘要

The specification and drawings show an embodiment of the present invention in the form of a device comprising one or more biosensors either placed or imbedded in a catheter, needle or combination of the two. The catheter or needle comprises exclusionary slits upstream of the biosensor(s), angled so that fluid flows in through the slits and down past the biosensors. The wires connecting the biosensors to external monitoring and/or analytical apparatus are wired through the catheter or needle material. Also provided herein are methods for detection of small molecules using the device described herein.
