Abstract: 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.

Abstract: An infusion system comprises a disposable wearable infusion device having a body arranged to be adhered to a patient's skin and a reservoir for holding a liquid medicament to be infused into the patient through a cannula extending from the device body to beneath the patient's skin. The system further includes a cannula driver arranged to be detachably joined with the infusion device and including a cannula. The cannula driver is arranged to drive the cannula into a deployed position extending from the device body to beneath the patient's skin. The cannula driver includes a release mechanism that separates the cannula driver from the infusion device after the cannula is in the deployed position.

Abstract: The application discloses a drug infusion system comprising a base and a drug dispenser. The base is configured to receive a cannula that delivers a drug to beneath a wearer's skin. The base is attachable to the skin of the wearer. The reusable drug dispenser is removably attachable to the base and has a pump unit configured to establish fluid communication between a removably attachable drug reservoir and the cannula. The pump unit pumps the drug to the wearer upon activation by the wearer. The pump unit may have an inlet to contact the drug within the reservoir, which may be a needle. The pump unit may also have a receiving unit to receive the reservoir. Such a receiving unit may be a tubular for a cylindrical reservoir, or may have a cavity or an encasing unit to hold the reservoir.

Abstract: A disposable wearable infusion device comprises a base that is arranged to adhere to the surface of a patient, a source arranged to provide a liquid medicament to be delivered to a patient, an outlet through which the medicament is delivered to the patient, a pump that pumps the medicament, and a conduit that conducts the pumped medicament to the outlet.

Abstract: A disposable wearable infusion device comprises a body arranged to be adhered to a patient's skin and to receive a cannula to extend from the infusion device to beneath the patient's skin, a reservoir for holding a liquid medicament to be infused into the patient, and a pump that displaces a volume of the liquid medicament from the reservoir to the cannula for delivery to the patient. The body has a port aligned with the cannula that permits the cannula to assume a deployed position to extend from the infusion device to beneath the patient's skin. The device further comprises a cover that blocks the port to preclude direct access to the cannula through the port after deployment.

Abstract: A body fluid sampling device is provided. A mesh may be used to guide blood or fluid to travel directly from the wound to an analyte detecting port on the cartridge. Thus the volume of blood or body fluid produced at the wound site irregardless of its droplet geometry can be reliable and substantially completely transported to the analyte detecting member for measurement.

Abstract: A method of controlling a penetrating member is provided. The method comprises providing a lancing device comprising a penetrating member driver having a position sensor and a processor that can determine the relative position and velocity of the penetrating member based on measuring relative position of the penetrating member with respect to time; providing a predetermined velocity control trajectory based on a model of the driver and a model of tissue to be contacted. In some embodiments, a feedforward control to maintain penetrating member velocity along said trajectory.
