Method for extracting interstitial fluid
First Claim
Patent Images
1. A method for extracting interstitial fluid from a user, the method comprising:
- adhesively attaching at least one floating ring of a sampling module for extracting interstitial fluid from a user'"'"'s body to the user'"'"'s body;
mounting the sampling module to the floating ring and attaching the sampling module to the user;
wherein the sampling module includes;
a housing assembly; and
a pressure ring assembly operatively contained within the housing assembly, the pressure ring assembly including;
a penetration member configured for penetrating a target site of a user'"'"'s body and, subsequently, residing in the target site and extracting ISF therefrom;
at least one pressure ring configured for applying pressure to the user'"'"'s body in a first vicinity of the target site while said penetration member is residing the target site; and
the at least one floating ring, the at least one floating ring including;
a proximal end;
a distal end; and
an adhesive layer disposed on the distal end of the floating ring;
wherein the adhesive layer provided for the adhesive attachment of the floating ring to the user'"'"'s body in a second vicinity of the target site, thereby influencing target site deformation during use of the sampling module;
penetrating a target site of the user'"'"'s body with the penetration member of the sampling module;
applying pressure to the first vicinity of the target site with the pressure ring;
extracting interstitial fluid from the target site via the penetration member.

Abstract
A method for extracting interstitial fluid from a target site of a user includes adhesively attaching a floating ring of a sampling module for extracting interstitial fluid to the user in the vicinity of a target site and then mounting the sampling module to the floating ring and attaching the sampling module to the user. Subsequently, the target site is penetrated with a penetration member of the sampling module. Pressure is then applied in another vicinity of the target site by a pressure ring of the sampling module and, thereafter, ISF extracted from the target site via a penetration member of the sampling module.
