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:
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. 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. A user interface is configured to relay at least one of, penetrating member performance or a penetrating member setting.
Abstract:
A tissue penetration device includes a penetrating member driver and a cartridge. A plurality of penetrating members are integrated with the cartridge. Each penetrating member is coupled to the penetrating member driver when advanced along a path into a tissue target. 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.
Abstract:
An integrated analyte measurement system includes a housing and a disposable configured to be positioned in the housing. A plurality of penetrating members are positioned in the disposable. A penetrating member driver is configured to be coupled to each of a penetrating member. A plurality of analyte sensors are positioned in the disposable. The disposable houses both used and unused penetrating members and analyte sensors.
Abstract:
Apparatus and methods consistent with certain principles related to the present invention include a first channel, where a fluid flows through the first channel, where the first channel comprises an upstream region, a tagging region downstream of the upstream region, where at least one analyte is tagged when the fluid flows through the tagging region, a capture region downstream of the tagging region, where at least one tagged analyte is captured when the fluid flows through the capture region. A second channel communicating the upstream region of the first channel with the first channel intermediate the tagging region and capture regions, where a portion of the fluid flows through the second channel and subsequently flows into the capture region of the first channel, and where the fluid flowing through the tagging region flows into the capture region before the portion of the fluid flowing through the second channel flows into the capture region of the first channel.
Abstract:
A method is provided for the analyte measurement by a user using an analyte measurement device. A penetrating member and unused analyte detecting member of the analyte measurement device are presented into an active position. The penetrating member is fired to prick the skin and bring a fluid sample to the analyte detecting member. The analyte level is measured. These three steps occur in less than 10 seconds.
Abstract:
A skin penetrating system is provided with a drive force generator and a disposable housing member. A plurality of penetrating members are positioned in the disposable housing member. Each penetrating member is coupled to the drive force generator. A plurality of analyte detecting members are each associated with a penetrating member and are positioned in the disposable housing member. Each analyte detecting member is positioned in a sample chamber. The sample chambers have openings for transport of a body fluid into the sample chamber. Each analyte detecting member is configured to determine a concentration of an analyte in a body fluid. A user interface is configured to relay at least one of, skin penetrating performance or a skin penetrating setting.
Abstract:
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.
