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:
A body fluid sampling system for use on a tissue site has a housing and a penetrating member driver at least partially within the housing. At least one cartridge is in the housing. The cartridge includes an analyte sensor in a sample chamber configured to receive body fluid from a wound in tissue created by a penetrating member. A penetrating member is associated with the sample chamber. Each penetrating member, and its associated sample chamber, has a combined occupied volume of no more than about 5.0 cm3. The penetrating member is at least partially co-located with the analyte sensor in the sample chamber. The sample chamber receives body fluid from a wound in tissue created by a penetrating member, and the analyte sensor determines analyte levels using a body fluid sample of less than about 1 microliter. A transport mechanism engages the cartridge. The penetrating member is operatively engaged with the penetrating member driver when moved into position by the transport mechanism. The driver provides the force to advance the penetrating member. A user interface on the housing displays information to a user.
摘要:
A method of penetrating tissue is provided. The method uses a lancet driver to advance a lancet into the tissue; advancing the lancet at a first desired velocity in a first layer of tissue; advancing the lancet at a second desired velocity in a second layer of tissue; and advancing the lancet at a third desired velocity in a third layer of tissue. In one embodiment, the method may including using a processor having logic for controlling velocity of the lancet in each layer of tissue.

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:
An improved penetrating tissue system is provided that reduces pain when penetrating tissue by providing controlled depth and velocity of penetration, stimulation and pressure to the targeted tissue without breaching a sterile environment. The system has user interfaces, human interfaces and low volume sample chambers.
摘要:
An assembly is described that combines blood chemical analysis with lancing in a single multiple-test disposable cartridge. The penetrating members can be assembled and sterilized without damaging the analytical chemistry, and the functioning of the present radical disc cartridge mechanism is not substantially modified.
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. A support is provided with a plurality of openings. Each opening receives a penetrating member. Each tip of a penetrating member is uncovered during launch of a penetrating member by the penetrating driver member. A user interface is configured to relay at least one of, skin penetrating performance or a skin penetrating setting.
摘要:
A blood testing apparatus includes a device for withdrawing blood, a membrane-type testing element, an evaluating device, and a display device forming a complete system which can be manipulated as a single piece of apparatus. Multiple testing elements can be inserted into the apparatus and brought successively to a work position for carrying out several measurements. The blood withdrawing device includes multiple pricking elements. One pricking element is pushed through one testing element and pricks the surface of the skin of a user. The pricking position is disposed so that blood withdrawn from the surface of the skin can impinge upon the testing element.
