Method and apparatus for a multi-use body fluid sampling device with analyte sensing
View Patent ↗A device for use with a penetrating member driver to penetrate tissue is provided. A plurality of penetrating members are coupled to a single cartridge and are operatively couplable to the penetrating member driver. The penetrating members are movable to extend radially outward from the cartridge to penetrate tissue. A plurality of analyte sensors are coupled to the single cartridge and are positioned on the cartridge to receive body fluid from a wound in the tissue created by the penetrating member.
1. A tissue penetration device, comprising:
an electronic penetrating member driver;
a disposable;
a plurality of penetrating members on a support and positioned in the disposable, each of the penetrating members coupled to the penetrating member driver when advanced along a path into a tissue target, wherein the support has a plurality of openings, each associated with a penetrating member for the penetrating member to exit;
a fracturable sterility barrier disposed on an outer surface of the support covering the plurality of openings without contacting the penetrating member; and
a device that breaks a portion of the fraturable sterility barrier covering the opening associated with the penetrating member during launch of the penetrating member so that the penetrating member exits the opening without contacting the sterility barrier; and
a plurality of analyte sensors each in a sample chamber, each of a sample chamber being associated with a the penetrating member, each of a sample chamber being positioned in the disposable to receive body fluid from a wound in the tissue created by the penetrating member and having a volume of no greater than 1 microliter.
2. A tissue penetration device, comprising:
