摘要:
A tissue penetrating system has a housing member. A plurality of penetrating members are positioned in the housing member. A tissue stabilizing member is coupled to the housing. A penetrating member sensor is coupled to the plurality of penetrating members. The penetrating member sensor is configured to provide information relative to a depth of penetration of a penetrating member through a skin surface.

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 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 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 of includes 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 skin penetrating system has a housing member and a plurality of penetrating members positioned in the housing member. A tissue stabilizing device is coupled to the housing member. A user interface is configured to relay at least one of, skin penetrating performance or a skin penetrating setting.
摘要:
A body fluid sampling system for use on a tissue site 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. A cartridge houses the penetrating member. The cartridge has first and second seals coupled to the penetrating member to maintain a sterile environment around a portion of the penetration member prior to penetrating member actuation.
