Biological Fluid Micro-Sample Management Device
A biological fluid collection device includes a collection module and an outer housing. The collection module includes a housing comprising a first end having a sample introduction opening, a second end having a sample dispensing opening, and a passageway extending between the sample introduction opening and the sample dispensing opening. A mixing chamber and a holding chamber are in fluid communication with the passageway such that a sample introduced into the sample introduction opening passes through the mixing chamber and subsequently into the holding chamber. The biological fluid collection device further includes a closure covering the first end, a cap covering the second end and including a vented plug, and an activation member adapted to force a sample contained in the holding chamber out of the sample dispensing opening. The collection module is positioned inside of the outer housing and the closure closes the open end of the outer housing.
Needle guide with centering for septum piercing
A pipetting device (2) for removing fluid from a sample vessel (52) includes a pipetting needle (4) and an auxiliary cannula (18) for piercing a septum, designed to guide the pipetting needle axially through the auxiliary cannula. The pipetting device has a guide arm (6), on the lower end (10) of which is arranged an end plate (12) that is axially displaceable along the guide arm against a resilient resistance. A centering device (14) inserts into the end plate of the guide arm, and at least three centering fingers (26) with conical bevels (34) are constructed on the radial outside of the centering device, distributed around the circumference thereof, and forming a holding-down device for the sample vessel. The disclosed construction makes possible to reliably pierce the septum of a sample vessel and to easily pull the pipetting needle out of the septum again even with thin pipetting needles.
METHOD AND DEVICE FOR TRANSFERRING LIQUIDS
The present invention relates to a pressure-tight storage vessel containing a liquid, wherein the storage vessel has an inner floor and an upper side and is closed in a pressure-sealing manner by a closure, and wherein the nature of the storage vessel allows pressure-sealing piercing with at least two hollow needles; and to a method for transferring a liquid from a storage vessel to a reaction vessel, the method comprising the following steps: supplying the storage vessel according to the invention, pressure-sealing piercing with a first hollow needle, which is connected to a rinsing-liquid tank, and pressure-sealing piercing with a second hollow needle, which is connected to the reaction vessel, introducing rinsing liquid from the rinsing-liquid tank, via the first hollow needle, into the storage vessel, the liquid being driven out of the storage vessel, via the second hollow needle, into the reaction vessel; and to an apparatus which is suitable for implementing the method according to the invention.
Isolation tube
A separation container for extracting a portion of a sample for use or testing and method for preparing samples for downstream use or testing are provided. The separation container may include a body defining an internal chamber. The body may define an opening, and the body may be configured to receive the sample within the internal chamber. The separation container may further include a seal disposed across the opening, such that the seal may be configured to seal the opening of the body, and a plunger movably disposed at least partially inside the internal chamber. The plunger may be configured to be actuated to open the seal and express the portion of the sample.
Apparatus and method for taking a sample from a fluid-conducting system
The present invention relates to an apparatus for sample taking from a fluid-conducting system, wherein the apparatus has at least one adapter which comprises at least one septum and at least one cannula displaceable relative to the septum, wherein the cannula is displaceable such that it penetrates the septum in a sample taking position and does not penetrate the septum in a flushing position; and wherein the adapter has at least one flushing region for a flushing medium which is arranged such that it is in fluid communication with the inner space of the cannula in the flushing position of the cannula; and wherein the apparatus has at least one receiving region having locking means for the fluid-conducting system by which the fluid-conducting system is fixable in a defined position relative to the adapter. The present invention furthermore relates to a blood treatment device and to a method for taking a sample from a fluid-conducting system.

DEVICES FOR COLLECTING BIOLOGICAL SAMPLES
Disclosed herein are devices, apparatus, systems, methods and kits for collecting and storing a fluid sample from a subject. A device for collecting the fluid sample can include a housing comprising a recess having an opening, a vacuum chamber in the housing and in fluidic communication with the recess, and one or more piercing elements that are extendable through the opening to penetrate skin of the subject. The vacuum chamber can be configured for having a vacuum that draws the skin into the recess. The recess can be configured having a size or shape that enables an increased volume of the fluid sample to be accumulated in the skin drawn into the recess.
Biological fluid collection device and collection module
