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 and a processor coupled to the drive force generator capable of changing the direction and magnitude of force exerted on the lancet during the lancing cycle. The driver further includes a human interface on the housing providing at least one output for communicating with the patient.

These and other objects of the present invention are achieved in a body fluid sampling system for use on a tissue site that 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. An analyte detecting member is positioned to receive fluid from a wound created by the penetrating member. The detection member is configured to determine a concentration of an analyte in the fluid using a sample of less than 1 μL of the fluid.

A tissue penetrating system includes a plurality of penetrating members each having a tip. A penetrating member driver is coupled to the plurality of penetrating members. Each tip of a penetrating member is uncovered during launch of the penetrating member by the penetrating member driver. A support is provided with a plurality of openings. Each opening receives a penetrating member.
摘要:
A tissue penetration device includes a penetrating member driver, a cartridge, and a plurality of penetrating members integrated with the cartridge. Each of a penetrating member is coupled to the penetrating member driver when advanced along a path into a tissue target. A user interface is configured to relay at least one of, skin penetrating performance or a skin penetrating setting.

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.
摘要:
A tissue penetrating system includes a plurality of cartridges each with a distal port and a proximal port. A plurality of penetrating members are provided, each coupled to a cartridge and having a sharpened distal tip and a shaft portion slidably disposed within the cartridge. A seal is formed by a fracturable material between the penetrating member and the cartridge. The seal is positioned at one or both of a distal port or a proximal port of the cartridge.
摘要:
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 drive force generator and a penetrating member operatively coupled to the force generator. The force generator moves the member 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. The drive force generator is configured to be controlled to follow a predetermined velocity trajectory into the tissue and out of the tissue. A tissue stabilizing member is associated with the device and at least partially surrounds an impact location of the penetrating member on the tissue site.
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.
摘要:
A method is provided for controlling a lancet velocity profile. A velocity of a moving lancet is measured at a known position. The measured velocity of the lancet is compared with an appropriate velocity for the lancet at the known position. A force is applied to the lancet to adjust the velocity of the lancet.
摘要:
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.
