A specimen collection assembly including a flow control member for adjustably altering a flow path is disclosed. In one configuration, the flow control member defines a regulation channel in fluid communication with a lumen of a cannula, wherein the flow control member is configured to adjustably alter an effective flow distance between the lumen of the cannula and an interior of an evacuated collection container. In another configuration, the flow control member is positioned to vary an effective cross-sectional area of at least one of an inlet port and an outlet port adapted to be in fluid communication with the lumen and the evacuated collection container.

There is provided an injector having an improvement in a linear launching profile. The injector of the present invention is used for launching a lancet to provide a pricking. The injector of the present invention comprises a plunger capable of launching the lancet in a pricking direction, an injector housing which surrounds the plunger, and an injector cap capable of being attached and detached with respect to the injector housing. In particular, an inner face of the injector cap is provided with a rib, and the rib and the plunger moving for the pricking are capable of contacting with each other.

A reagentless whole-blood analyte detection system that is capable of being deployed near a patient has a source capable of emitting a beam of radiation that includes a spectral band. The whole-blood system also has a detector in an optical path of the beam. The whole-blood system also has a housing that is configured to house the source and the detector. The whole-blood system also has a sample element that is situated in the optical path of the beam. The sample element has a sample cell and a sample cell wall that does not eliminate transmittance of the beam of radiation in the spectral band.

An apparatus for performing phlebotomy through a peripheral intravenous line. The apparatus includes an introducer and a catheter configured to advance the catheter through a peripheral intravenous line. A y-adapter with a port of larger diameter is configured to receive the catheter and place in fluid communication with the peripheral intravenous line. When advanced the catheter is configured to transport a bodily fluid (i.e. blood) to a volume outside of the body.

A specimen collection assembly (100) including a flow control member (106) for adjustably altering a flow path is disclosed. In one configuration, the flow control member (106) defines a regulation channel (166) in fluid communication with a lumen of a cannula (112), wherein the flow control member (106) is configured to adjustably alter an effective flow distance between the lumen of the cannula (112) and an interior of an evacuated collection container. In another configuration, the flow control member (106) is positioned to vary an effective cross-sectional area of at least one of an inlet port (346) and an outlet port (350) adapted to be in fluid communication with the lumen and the evacuated collection container.

A single use lancing device comprising: a housing (10) defining a cavity; a needle assembly (12) comprising a needle (50) and a needle holder (52) and located within the cavity; a release member (16); and a spring (14) arranged to bias the needle assembly in a forward direction relative to the release member; wherein the release member comprises retaining arms (38) and is movable relative to the housing between a primed position in which the retaining arms are arranged to cooperate with the housing to restrain the needle assembly in a primed position, and a deployed position in which the restraining arms are arranged to release the needle assembly to deploy the needle.

The present invention includes a system for withdrawing body fluids. The system includes a drive unit having a plunger which is moved from a resting position into a lancing position in order to carry out a lancing process and a lancing unit containing a lancet with a needle. The plunger and lancet are coupled together by a form fit in order to carry out a lancing process. The invention additionally concerns a method for temporarily extending a needle from a device for withdrawing body fluid as well as a lancing unit that can be attached to the drive unit.

Embodiments of the present invention provide magnetic lancet devices and methods for driving a lancet. For example, a magnetic lancet device may include a driving mechanism having a plurality of magnets and a lancet coupled to the driving mechanism. A magnetic interaction between the plurality of magnets is configured to drive the lancet from an engaged position to a penetrating position.

An integrated testing device is described, for example for testing bodily fluids. The device has a test component, a reservoir containing a test fluid, and a control vessel. The reservoir discharges test fluid into the control vessel, which discharges the test fluid in a controlled way to the test component.

A needle assembly is disclosed. The needle assembly includes a housing having a flash chamber, and having a distal end and a proximal end engageable with a specimen collection container. The assembly includes a cannula having a patient end, a non-patient end, and a sidewall extending therebetween defining a cannula interior. The patient end of the cannula projects at least partially from the distal end of the housing, and the cannula interior is in fluid communication with the flash chamber. The assembly further includes a shield restrainably engaged with a portion of the housing and axially transitionable over the patient cannula from a retracted position in which the patient end is exposed, to an extended position in which the patient end is shielded by at least a portion of the shield, wherein at least a portion of the flash chamber is visible in the retracted position.
