The invention relates to the field of integrated systems which comprise a test element and a lancet which can be firstly used to make a wound in a skin opening in order to collect a sample. The sample is subsequently directly taken up by the test element in the process of which it comes into contact with a reagent contained in the test element and results in an optically detectable change in a test field. The change in the test field is detected by means of an analytical unit which is optically contacted with the test field via at least one light-conducting element.

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.

Devices are provided to automatically access blood from beneath or within skin. These devices include a plurality of injectors configured to drive needles into the skin and draw samples of blood into the device. These devices additionally include a plurality of sensors which can detect a target analyte in the blood samples received by the device. These devices further include a user interface, which may prompt the user to self-administer a dose of a substance, or accept a user input which could affect or otherwise influence the activation of the device (i.e., the firing of needles to draw blood samples into the device and detect an analyte). These devices can be wearable and configured to automatically access blood from skin, for example, to access blood from the skin at one or more points in time after the user has self-administered a dose of a substance.

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 biological property testing device includes a base comprising a primary surface extending in a base plane, and a first lancet station supported by the base. A first test strip channel provided in the base can have a main channel portion extending generally parallel with the base plane, and an angled channel portion that forms an angle with the main channel portion between 5 degrees and 90 degrees. The first test strip channel can house a biological test strip oriented so that a meter connecting end of the biological test strip is adjacent to the main channel portion and a sample end of the biological test strip is adjacent to the angled channel portion.

An apparatus includes a catheter, an introducer having a first member and a second member, a locking mechanism coupled to a distal end of the first member and configured to couple the introducer to a peripheral intravenous line, and an actuator coupled to the catheter. The actuator is configured to move from a first configuration, in which the catheter is disposed within the introducer, toward a second configuration to move the second member to a distal position relative to the first member. A portion of a guide of the second member being distal to the first member when the second member is in the distal position. The actuator is configured to move relative to the second member to be placed in the second configuration when the second member is in its distal position such that the catheter is disposed within and extending past an end of the peripheral intravenous line.

An instrument advancement device includes a housing comprising a fluid path, a distal end, and a proximal end, an instrument disposed within the housing, an advancement element, where in response to movement of the advancement element with respect to the housing, the instrument is configured to advance distal to the distal end of the housing, a small sample dispense device connected to the proximal end of the housing, and a blood collection device connected to a proximal end of the small sample dispense device. The blood collection device is configured to receive an evacuated blood collection container, where the small sample dispense device is detachable from the housing and configured to dispense a blood sample.

An instrument advancement device may include a housing comprising a distal end and a proximal end; an instrument disposed within the housing; an advancement element, wherein in response to movement of the advancement element with respect to the housing, the instrument is configured to advance distal to the distal end of the housing, and a blood sample collection tube inserted into the distal end of the housing, wherein the blood sample collection tube is configured to receive a small volume blood sample.

An infusion and blood collection device allows clean blood collections into a collection tube via a previously installed angiocatheter without interrupting the administration of intravenous therapies after initial installation. The device includes a fluid flow restriction device to control the blood collection flow rate to prevent contamination of the collected blood draw with the IV therapy fluid being simultaneously infused through the angiocatheter.

Bodily fluid sample collection systems, devices, and method are provided. The sample is collected at a first location and subjected to a first sample processing step. The sample may be shipped to a second location and subjected to a second sample processing step that does not introduce contaminants into a plasma portion of the sample formed from the first processing step. The sample may also be mixed with other material(s) in the collection device.
