摘要:
A body fluid sampling system is provided for use on a tissue site. In one embodiment, the system (10) comprises a cartridge (12); a penetrating member driver 34; a plurality of penetrating members (18) arranged in a radial configuration on the cartridge (12) such that sharpened distal tips of the penetrating members (18) point radially outward. An active one of the penetrating members may be operatively coupled to the penetrating member driver (34) so the penetrating member driver moves the active one along a path out of a housing (30) having a penetrating member exit, into the tissue site, stopping in the tissue site, and withdrawing out of the tissue site. The system further includes a plurality of analyte detecting members.

A plurality of Point-of-Care (POC) tests on a single cartridge (300) is provided such that sequential or nonsequential tests may be performed in an integrated fashion without changing the test cartridge. Each cartridge can contain a penetrating member sensor (302) combination in a radial disk format, interrogated and read by a single illumination/detection device. Alternatively a series of tests can be measured electrochemically and reported. Only those tests, which are required at the time, the sample is taken need to be reported, though all tests are carried out.
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 (24,183) used for sampling blood. Electric field coils or solenoids (20,30) may drive the lancet (24,183) using electromagnetic force. Advancement and retraction of a lancet (24,183) may be controlled by a feedback loop monitoring the position and velocity of the lancet (24,183) embodiments of the lancet driver (48) can be configured to follow a predetermined tissue lancing profile. Embodiments of the invention include a lancet (24,183) and method for using a lancet (24,183) to maintain the patency of the wound tract once the lancet (24,183) has cut into the skin.
摘要:
An electric lancet actuator (16) and method of using same. An embodiment provides control of a lancet (36) used for sampling blood by puncturing the skin. The lancet (36) can be contained within a stationary housing which interacts with the proximal or driving end of lancet (36) and allows the distal or front end of the lancet (36) to protrude beyond the stationary housing and puncture the skin. Electric field coils or solenoids (38) drive the lancet (36) using either magnetic attraction or repulsion.
摘要:
A body fluid sampling system for use on a tissue site includes a drive force generator. A plurality of penetrating members are housed in a penetrating member housing. Each of penetrating member is configured to be coupled to the drive force generator. A plurality of analyte sensors are housed in an analyte sensor housing. Each analyte sensor is associated with a penetrating member. The analyte sensor housing is in a surrounding relationship to the penetrating member housing and positioned to provide that upon launch of a penetrating member, and penetration of a penetrating member at a skin surface, blood flows into the analyte sensor.

A device is provided for fluid delivery. The device comprises a cartridge (1100) having a plurality of cavities and a plurality of penetrating members (1002). The plurality of penetrating members (1002) are each at least partially contained in cavities of the cartridge (1100) wherein the penetrating members (1002) are slidably movable to extend outward from openings on said cartridge (1100) to penetrate tissue. Each of the penetrating members (1002) comprises a needle (1002) with a lumen coupled to a canister (1017) containing a material to be injected.
摘要:
A lancet driver is provided wherein the driver exerts a driving force on a lancet during a lancing cycle and is used on a tissue site. The driver comprises of a drive force generator for advancing the lancet along a path into the tissue site, and a sensor configured to detect lancet position along said path during the lancing cycle.
摘要:
A method and apparatus (2) for obtaining a sample of blood. An embodiment consists of an apparatus (2) which integrates lancing (12), sample collection, and analysis. The presence of patients finger on the active sampling area can be sensed by monitoring the pressure applied by the finger on the device (2).
