Abstract:
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.
Abstract:
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.
Abstract:
Reducing the volume or drag on skin or sharpness of the penetrating member entering the wound during the cutting process will reduce the pain associated with lancing, and result in less power desired for retraction of the penetrating member from the skin. A variety of other penetrating member configuration as shown in the application.
Abstract:
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.
Abstract:
Blood samples can be collected without substantial contamination from ambient air, such that the blood sample may be analysed accurately for gaseous components such as oxygen and carbon dioxide. An embodiment of th device has integrated actuation, lancing, and sample acquisition components, which in some embodiments are miniaturized and/or disposable.
Abstract:
An agent injection device is provided that is capable of injecting an agent to a known predetermined tissue depth. An injection member has an elongate injection shaft with an outlet port configured to dispense an agent at a controllable time. A controllable driver is coupled to the elongate injection shaft and is configured to drive the injection member into target tissue. A velocity control system is in communication with the controllable driver and is configured to control the velocity of the elongate injection shaft.
Abstract:
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.
Abstract:
These and other objects of the present invention are achieved in a body fluid sampling system for use on a tissue site that 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. A user interface is configured to relay at least one of, penetrating member performance or a penetrating member setting.
Abstract:
A moving coil tissue penetration device includes a magnetic source that produces a magnetic field in a magnetically active region. A cylindrical coil is secured to a translation substrate and disposed at least partially within the magnetically active region. A sharpened member is configured to penetrate tissue and mechanically coupled to the translation substrate.
