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.
摘要:
An apparatus having a shaft that can sense the depth of penetration, for penetrating into an object (the substrate). The substrate being penetrated has impedance that varies according to the depth under a surface of the substrate. The shaft has a tip for penetration and has conductive ends near to the tip of the shaft. A change of impedance of material of the object between the conductive ends can be sensed to provide information on the depth of penetration. A processor can be provided external to the object being penetrated by the shaft to gather and process the impedance information to determine whether the desired depth has been achieved.

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 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 being coupled to a cartridge. Each penetrating member has 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. A user interface is configured to relay at least one of, skin penetrating performance or a skin penetrating setting.
摘要:
A method of lancing the tissue of a patient provides a tissue penetration element with a tip configured to penetrate tissue and a shaft portion. The tissue penetration element is disposed in proximity to the tissue of the patient. The tissue penetration element is driven distally towards the tissue of the patient. Contact is made between the tip and the tissue of the patient. The tip is advanced into the tissue during a penetration stroke to a position of maximum inward displacement. The tissue penetration element is allowed to settle upon reaching the point of maximum inward penetration for at least about 1 millisecond with no driving force imposed on the tissue penetration element. The tissue penetration element is displaced proximally over a withdrawal stroke and the tip is removed from the tissue.

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.
摘要:
A sampling module includes a housing and a penetrating member positioned in the housing. An attachment device is coupled to the housing. The attachment device is tiltably attached to a tissue interface that permits the tissue interface surface to tilt. The tissue interface includes an opening for the penetrating member to pass there through.

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.
摘要:
In one embodiment of the present invention a lancet is provided that has a sharpened distal tip, a shaft portion and a proximal drive head. The proximal drive head has a transverse dimension that is substantially larger than a transverse dimension of the shaft portion adjacent to the proximal drive head.
摘要:
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.
