Methods and apparatus for penetrating tissue
View Patent ↗These and other objects of the present invention are achieved in a body fluid sampling system for use on a tissue site that includes an electrically powered drive force generator. A penetrating member is operatively coupled to the force generator. The force generator moves the member along a path out of a housing having a penetrating member exit, into the tissue site, stops in the tissue site, and withdraws out of the tissue site. An analyte detecting member is positioned to receive fluid from a wound created by the penetrating member. The detection member is configured to determine a concentration of an analyte in the fluid using a sample of less than 1 μL of the fluid. A user interface is configured to relay at least one of, penetrating member performance or a penetrating member setting.
1. A body fluid sampling system for use on a tissue site, the system comprising:
an electronic drive force generator;
a penetrating member having an elongate portion operatively coupled to said force generator;
a sterility enclosure covering at least a tip of said penetrating member, said sterility enclosure removed from said penetrating member prior to actuation of the penetrating member and positioned so that the penetrating member will not contact said enclosure during actuation;
an analyte detecting member positioned to receive fluid from a wound created by said penetrating member, said analyte detecting member configured to determine a concentration of an analyte in the fluid using a sample of less than 1 μL of the fluid;
a processor coupled to the electronic drive force generator, the processor including a user profile of a user in a memory for setting penetration parameters of penetrating member to create the puncture wound for a successful penetration to achieve a desired body fluid volume;
an audio device configured to relay information to a user of the system and to receive audio input from a user, the audio input in operation being configured to modify the user profile based on additional audio user input; and
a user interface coupled to the processor, the user interface including or being coupled to one or more alarms to provide a user with a reminder that a next target penetrating event is needed.
2. A body fluid sampling system for use on a tissue site, the system comprising:
an electronic drive force generator;
a penetrating member having an elongate portion operatively coupled to said force generator;
a coupler that couples the electronic drive force generator with the penetrating member;
an analyte detecting member positioned to receive fluid from a wound created by said penetrating member, said analyte detecting member configured to determine a concentration of an analyte in the fluid using a sample of less than 1 μL of the fluid;
a processor coupled to the electronic drive force generator, the processor including a user profile of a user in a memory for setting penetration parameters of penetrating member to create the puncture wound for a successful penetration to achieve a desired body fluid volume;
an audio device configured to relay information to a user of the system and to receive audio input from a user, the audio input in operation being configured to modify the user profile based on additional audio user input; and
a human interface coupled to the processor, the human interface including or being coupled to one or more alarms to provide a user with a reminder that a next target penetrating event is needed.
