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.

This disclosure provides equipment and processes for blood glucose management. Embodiments may comprise a lancet device that includes a base that supports a lancet and a cover. The cover can move controllably from an un-depressed position to a depressed position when a predetermined force is applied. The cover can provide access to the lancet in the depressed position. In another aspect, a biological test kit may include a reusable module and a disposable module. The disposable module may include one or more lancet devices such as that described above to collect a biological sample, one or more strip stations supporting biological strips and a disposable module connector. The reusable module may support measuring equipment to measure a property of the biological sample and a reusable module connector that engages removably with the disposable module connector.

This disclosure relates to a system and method for drawing blood from a user by skin puncture instead of venous puncture and storing it for analysis. The system includes a receptacle configured to engage an area of skin of the user at a blood draw location and store blood drawn from the user; a lancet device disposed within the receptacle configured to puncture the skin of the user at the blood draw location; a vacuum device configured to reduce a pressure within the receptacle such that the skin at the blood draw location is drawn into the receptacle before the lancet device punctures the skin, and to enhance blood flow while blood is drawn from the user; and a housing configured to house the receptacle, the lancet device, and the vacuum device. The receptacle, the lancet device, and the vacuum device may be modular and removably coupled with the housing.

A blood sampling transfer device that includes a lancing tape having a flow channel and a transfer cartridge removably connected to the lancing tape is disclosed. The blood sampling transfer device provides a closed system that reduces the exposure of a blood sample to both skin and environment and provides fast mixing of a blood sample with a sample stabilizer.

A blood separation and testing system for a blood sample is disclosed. The blood separation and testing system includes a blood sampling transfer device adapted to receive a blood sample, a blood separation device, and a blood testing device. The blood separation device is adapted to receive a portion of the blood sampling transfer device such that with the blood sampling transfer device received within the blood separation device and a rotational force applied to the blood sampling transfer device, a plasma portion of the blood sample is separated from a cellular portion of the blood sample. The blood testing device is adapted to receive a portion of the blood sampling transfer device to analyze the plasma portion of the blood sample and obtain test results.

The present invention provides a liquid sampling, storage, transfer and delivery device comprising housing containing a porous nib. The porous nib in the device contacts the sample, collects the sample, stores the sample, transports the sample inside its porous matrix and releases the sample from the porous matrix upon demand.

A lancing system can include a device body having a sealing device coupled to a lancing end, a lancing shaft slideably coupled to the lancing end, a lancing spring coupled to the lancing shaft, a release mechanism, a main shaft slideably coupled with a free end of the device body in communication with the release mechanism, a piston coupled to the main shaft, a vacuum spring coupled to the piston, and a shaft coupler having at least two separable portions for removably coupling the lancing shaft to the main shaft. The system can include a lance tool having an insertion portion and a removal portion. A method can include creating a first portion of a vacuum, lancing a surface, and creating a second portion of a vacuum.
