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.

A skin pricking device includes a housing having an opening formed in a proximal end thereof; a spring mounted lancet including a needle within a casing having body and cap parts, interconnected by a separable coupling. The cap part has a cap projecting through the opening allow a user to grip and remove the cap. The device further includes a trigger for firing the lancet. Turning the cap part moves the entire lancet, engaging a trigger stop surface on the distal body part of the lancet with a trigger catch and further biasing the trigger to block the lancet. Further turning of the cap part over a second angle relative to the housing causes the cap part to move in a proximal direction by a further, second distance, thereby axially separating the cap part from the body part, whereby the cap part can then be removed from the device.

The disclosed apparatus, systems and methods relate to devices, systems and methods for the collection of bodily fluids involving a single-use actuation and retraction mechanism disposed within a collector.

An arrangement for producing a sample of body fluid from a wound opening created in a skin surface at a sampling site includes: a housing, the housing comprising a first opening; a skin interface member disposed in the first opening, the skin interface member comprising an inner member having a second opening, and an outer member at least partially surrounding the inner member and attached to the first opening; and at least one skin-penetration member configured and arranged to project within the second opening. Arrangements having alternatively constructed skin interface members are also described.

A biological fluid separation device that is adapted to receive a multi-component blood sample is disclosed. After collecting the blood sample, the biological fluid separation device is able to separate a plasma portion from a cellular portion. After separation, the biological fluid separation device is able to transfer the plasma portion of the blood sample to a point-of-care testing device. The biological fluid separation device of the present disclosure also provides a closed separation and transfer system that reduces the exposure of a blood sample and provides fast mixing of a blood sample with a sample stabilizer. The biological fluid separation device is engageable with a blood testing device for closed transfer of a portion of the plasma portion from the biological fluid separation device to the blood testing device. The blood testing device is adapted to receive the plasma portion to analyze the blood sample and obtain test results.

The present disclosure relates to a system, method, and kit for particle detection and analysis. Devices disclosed herein may include at least an optical source, a fludic chip containing a multiplex bead array, and a detection module, wherein the sample flows within the fludic chip past a detection window, where the cells or particles are imaged by an image acquisition and analysis module that may include an optical detector. The image acquisition and analysis module counts the labeled particles and software allows for analysis of bead population.

Described here are meters and methods for sampling, transporting, and/or analyzing a fluid sample. The meters may include a meter housing and a cartridge. In some instances, the meter may include a tower which may engage one or more portions of a cartridge. The meter housing may include an imaging system, which may or may not be included in the tower. The cartridge may include one or more sampling arrangements, which may be configured to collect a fluid sample from a sampling site. A sampling arrangement may include a skin-penetration member, a hub, and a quantification member.

A lancing device has a domed structure that can be depressed by application of a force by a user's finger so as to expose the tip of a needle. The domed structure is configured to move from a non-depressed state to a depressed state in a manner that allows for the piercing of the user's finger. The domed structure may then recoil to its original, non-depressed position upon the user ceasing to apply the force. Other embodiments of a lancing device are disclosed.
