BIOSENSOR INTRODUCERS ETC.

摘要

A biosensor introducer comprises an arcuate needle (15), a biosensor (16) secured to the arcuate needle behind its point, and means (17) for inserting the needle under the skin so as to introduce the biosensor subcutaneously. The biosensor (16) may comprise a length of flexible plastics tube with a notch (19) adjacent a leading end (20), whereby the notch can be entered by the needle (15) and wereby the needle can be withdrawn from the notch to leave the biosensor like a stitch under the skin. Alternatively, the biosensor (16) may be permanently attached to the needle (15) by bonding a leading end portion in a portion (39) of the needle having a reduced cross-section, with the leading end (20) of the biosensor abutting a shoulder (40) where the cross-section changes behind the point of the needle.
