The integrated puncturing and analyzing element includes a puncturing element having a tip for generating a puncture wound in a body part and an elongated flat test strip having a top side and a bottom side. The analyzing instrument having a housing has a holder for holding an integrated puncturing and analyzing element, and a coupling unit which is provided such as to couple the puncturing element to a drive by means of which a puncturing movement of the puncturing element is driven, during which it is moved on a path of movement in the puncturing direction during an advancement phase and, after reaching a reversal point of the puncturing movement, is moved opposite to the puncturing direction in a return phase. The puncturing element is arranged to be parallel to the test strip and such as to be mobile with respect to the test strip along the movement path. The integrated puncturing and analyzing element is held in the holder such that, in a sample application position of the test strip, the top side of the test strip is facing upward and, in a puncturing position of the test strip, the tip of the puncturing element is moved beyond an end of the test strip which is its front end in the puncturing direction, in order to generate a puncture wound in a body part. A sample application area for manual application of a drop exiting from the puncture wound of the body part is provided on the top side of the test strip such that, in the sample application position, the drop is applied to the sample application area from directly above. The housing is shaped to allow access to the sample application area of a test strip positioned in the sample application position, and to allow access to the front end of a test strip which is positioned in the puncturing position. | 10-23-2008 |
20090043225 | FLASHBACK BLOOD COLLECTION NEEDLE - The invention is a self-venting blood collection needle assembly for the extraction of at least one fluid sample into an evacuated container for laboratory testing, this blood collection needle assembly providing a clear or translucent flashback chamber for blood to flow into, for visualization by the user to confirm successful vein entry.

20140309553 | KITS AND METHODS FOR SEPARATING A TARGET ANALYTE FROM A SUSPENSION - This disclosure is directed to kits and methods for extracting a target analyte from a biological fluid in real time. The biological fluid, therefore, does not need to be stored or shipped/delivered. Isolating the target analyte in real-time allows for on-the-spot processing with minimal, if any, down time between collection and testing. Furthermore, isolating in real time may also allow for the biological fluid to be extracted, processed, and returned—similar to that of dialysis—to permit for more volume to be processed and tested. In one aspect, an inner surface of a conduit may include a coating having a high affinity for the target analyte. The conduit may also include features which create turbulent flow to permit all portions of the biological fluid to come into contact with the coating. In another aspect, a capture chip is used to isolate the target analyte from the biological fluid. | 10-16-2014 |

20160113560 | FLUID DIVERSION MECHANISM FOR BODILY-FLUID SAMPLING - A device includes a pre-sample reservoir, an actuator mechanism, and a diverter. The pre-sample reservoir can be fluidically coupled to a delivery member to receive and isolate a predetermined volume of bodily-fluid withdrawn from a patient. The actuator mechanism is operably coupled to the pre-sample reservoir such that, when actuated, a negative pressure is formed in the pre-sample reservoir that urges the bodily-fluid to flow into the pre-sample reservoir. The diverter can selectively control fluid flow between the delivery member and the pre-sample reservoir. The diverter includes a flow control mechanism that defines a first fluid flow path and a second fluid flow path. The diverter is movable between a first configuration in which the bodily-fluid flows through the first fluid flow path to the pre-sample reservoir, and a second configuration in which the bodily-fluid flows through the second fluid flow path to a sample reservoir coupled to the diverter. | 04-28-2016 |
