摘要:
A body fluid sampling system for use on a tissue site includes a single drive force generator. A plurality of penetrating members are operatively coupled to the force generator. The force generator moves each of the members along a path out of a housing with a penetrating member exit, into the tissue site, stops in the tissue site, and withdraws out of the tissue site. A flexible support member couples the penetrating members to define a linear array. The support member is movable and configured to move each of the penetrating members to a launch position associated with the force generator.
摘要:
A device for use with a gripper is provided. A cartridge is provided that defines a plurality of cavities. A plurality of penetrating members are at least partially contained in the cavities of the cartridge. The penetrating members are slidably movable to extend outward from the cartridge to penetrate tissue. Each cavity has a longitudinal opening that provides access to an elongate portion of the penetrating member. A sterility barrier is coupled to the cartridge. The sterility barrier covers a plurality of the longitudinal openings. The sterility barrier is configured to be moved so that the elongate portion is accessed by the gripper without touching the barrier.
摘要:
A body fluid sampling system is provided for use on a tissue site. A drive force generator is coupled to penetrating members. The penetrating members are at least partially housed in a penetrating member housing. The penetrating member housing has openings for the penetrating members. The penetrating members are launched along a launch path by the drive force generator through an opening in the penetrating member housing. Analyte sensors are housed in a analyte sensor housing. Each analyte sensor is associated with a penetrating member. The analyte sensor housing and the penetrating member housing are coupled to provide that each analyte sensor is positioned out of a launch path of a penetrating member. The analyte sensor housing includes desiccant pockets for receiving desiccant plugs

摘要:
A tissue penetration device and method of using same that may include a lancet module or sampling module. The sampling module may optionally be in a cartridge configuration and include sampling and analyzing functions, which may be integrated.
摘要:
A system is provided that controls movement of a lancet. One or more processors execute program instructions and receive a data set. The program instructions are executed to cause the processor to, cause force to be applied to the lancet to thereby cause the lancet to move in a first direction toward a target, monitor position and speed of the lancet as the lancet moves in the first direction, adjust the application of force to the lancet as the lancet moves in the first direction to achieve a desired speed of the lancet, and adjust the application of force to the lancet when the lancet contacts the target so that the lancet penetrates the target within a desired range of speed.
摘要:
A tissue penetration device and method of using same. The tissue penetration device may optionally include sampling and analyzing functions, which may be integrated. An embodiment provides control of a lancet used for sampling blood. Electric field coils or solenoids may drive the lancet using electromagnetic force. Advancement and retraction of a lancet may be controlled by a feedback loop monitoring the position and velocity of the lancet embodiments of the lancet driver can be configured to follow a predetermined tissue lancing profile. Embodiments of the invention include a lancet and method for using a lancet to maintain the patency of the wound tract once the lancet has cut into the skin.
摘要:
A device for use with a penetrating member driver to penetrate tissue is provided. The device includes a single cartridge coupled to a plurality of penetrating members and 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 optical analyte sensors are coupled to the single cartridge and positioned to receive body fluid from a wound in the tissue created by the penetrating member.
摘要:
A skin penetrating system includes a housing member and a penetrating member positioned in the housing member. An analyte detecting member is coupled to a sample chamber. The analyte detecting member is configured to determine a concentration of an analyte in a body fluid using a sample of less than 1 nullL of a body fluid disposed in the sample chamber. A tip of the penetrating member is configured to extend through an opening of the sample chamber.
