Devices, systems and methods for extracting bodily fluid and monitoring an analyte therein
First Claim
1. A system for extracting bodily fluid from the skin, the system comprising:
- a penetration member configured for penetrating a target site in the skin and accessing bodily fluid therein; and
means for applying pressure to the skin in an oscillating manner, the pressure application means extending substantially concentrically about the penetration member.

Abstract
Systems and methods are provided for extracting a bodily fluid sample (e.g., an interstitial fluid sample) and monitoring an analyte therein. Certain of the systems include a a penetration member configured for penetrating and residing in a target site of a user'"'"'s skin layer and, subsequently, extracting a fluid sample therefrom. The system also includes a pressure ring(s) adapted for applying pressure to the user'"'"'s skin layer in the vicinity of the target site. The system is configured such that the pressure ring(s) is capable of applying pressure in an oscillating manner. Certain methods include penetrating the skin and applying pressure to the skin in an oscillating manner.

25. A system for extracting bodily fluid from skin and monitoring at least one analyte therein, the system comprising:
-
a penetration member configured for penetrating a target site within the skin and extracting fluid therefrom;
at least one pressure ring adapted for applying pressure in an oscillating manner to the skin layer in the vicinity of the target site about the penetration member;
means for measuring the at least one analyte in bodily fluid extracted by the penetration member; and
means for controlling the oscillation frequency of the at least one pressure ring. - View Dependent Claims (26, 27, 28, 29)

30. A method for extracting bodily fluid from skin and monitoring at least one analyte therein, the method comprising:
-
penetrating a target site within the skin;
applying pressure in an oscillating manner to the skin in the vicinity of the target site;
extracting fluid from the skin; and
measuring the at least one analyte in the extracted fluid. - View Dependent Claims (31, 32, 33, 34)

35. An interstitial fluid extraction device comprising:
-
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;
a rotatable gear wheel; and
at least one pressure ring 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, wherein the gear wheel is adapted to interact with the pressure ring such that rotation of the gear wheel in a first direction imparts translational motion to the pressure ring progressively towards the user'"'"'s skin layer allowing pressure to be applied to the user'"'"'s skin layer and rotation of the gear wheel in a second direction, opposite to the first direction, imparts translational motion to the pressure ring progressively away from the user'"'"'s skin layer. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55)
