摘要： An interstitial fluid (ISF) extraction device includes a penetration member configured for penetrating a target site of a user's skin layer and, subsequently, residing in the user's skin layer and extracting an ISF sample therefrom and at least three concentrically-arranged pressure rings, each adapted for applying pressure to the user's skin layer in the vicinity of the target site while the penetration member is residing in the user's skin layer. In addition, the ISF extraction device is configured such that (i) the pressure rings apply pressure in an oscillating manner with asymmetric deployment and retraction cycles and (ii) only one of the at least three concentrically-arranged pressure rings is deployed at a time, thereby mitigating an ISF glucose lag of the ISF sample extracted by the penetration member.
