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.

Sensors are disclosed that detect whether a cannula is properly inserted to its full depth in a subject's skin. The sensors may be used with a blood glucose monitor, or with a continuous insulin infusion pump, infusion set, or other system involving intermittent or continuous testing and/or drug delivery.

Bodily fluid sample collection systems, devices, and method are provided. The device may comprise a first portion comprising at least a sample collection channel configured to draw the fluid sample into the sample collection channel via a first type of motive force. The sample collection device may include a second portion comprising a sample vessel for receiving the bodily fluid sample collected in the sample collection channel, the sample vessel operably engagable to be in fluid communication with the collection channel, whereupon when fluid communication is established, the vessel and/or another source provides a second motive force different from the first motive force to move a majority of the bodily fluid sample from the channel into the vessel.

Devices are provided to automatically access blood from beneath or within skin. These devices include an injector configured to drive a needle into the skin and subsequently to retract the needle from the skin. These devices additionally include a seal to which suction is applied. To drive the needle into the skin, the needle is first driven through the seal, creating at least one hole in the seal. The suction applied to the seal acts to draw blood from the puncture formed in the skin by the needle, through the at least one hole in the seal, and to a sensor, blood storage element, or other payload. 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 while a wearer of a device is sleeping.

A method of performing an intravenous drip injection includes a first step, a second step, a third step and a fourth step. A first step includes starting dosing an infusion solution containing a predetermined component by the intravenous drip injection to a dosing recipient. A second step includes extracting a body fluid from the dosing recipient being dosed with the infusion solution. A third step includes measuring a concentration of the predetermined component in the extracted body fluid. A fourth step includes varying the concentration of the predetermined component in the infusion solution, corresponding to the concentration of the predetermined component in the body fluid.

The present invention provides method and apparatus for minimally-invasive capillary blood extraction comprising an apparatus capable of the harnessing the energy from frequent natural mammalian movements and then converting it into forces needed to execute skin lancing, specifically an insertion of a lancet in the body of the mammal. The apparatus consists of a rotational and a translational member which work together to effectively translate an angular displacement of the rotational element caused by mammalian movements to translational displacement of a sliding element at an angle to the plane which the force from the mammal was applied in. The ability of the invention to harness free energy and efficiently use that energy for actuating a lancet and facilitating blood extraction allows for the miniaturization of blood sampling technology into a wearable device.

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.
