The present invention relates to a trigger mechanism for a sample collection device, the trigger mechanism comprising a trigger element and a preloaded plug with a blade, whereas the trigger element is relatively movable to the plug, the trigger mechanism being configured to release the preloaded plug with the blade for perforating a user's skin for blood collection, the trigger element further being arranged to be activated and moved relatively to the plug by an activation force created by a skin part being vacuum-sucked into the sample collection device and pressing directly or indirectly against the trigger element.

An inserter for a medical device, where the inserter includes a housing having a first end with an opening therein, an actuator connected to a first gear, an actuator biasing element, a cam gear assembly including a cam member and a second gear, a cam bridge follower in contact with the cam member, and a first plunger assembly having a first plunger and a first biasing element.

A method of manufacturing a skin pricking lancet includes: thermoforming a plastic component; locating the thermoformed component and, optionally, one or more further plastic components around a lancet mechanism; and joining the located component(s) to form a hermetically sealed enclosure surrounding the lancet mechanism, the component(s) being formed and joined to provide a housing that structurally supports the lancet mechanism during use, and a cap breakable from the housing to facilitate firing of the lancet mechanism.

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.

An integrated testing device and method are disclosed. The device includes an integral reservoir for a test fluid, and an actuator, so that the test fluid can be dispensed to facilitate the test.

Disclosed is a replaceable blood lancet device in which a needle unit including a needle carrier and a front slider is used as inserted in a tubular barrel, and the used needle unit or needle carrier is replaced after use. The replaceable blood lancet device minimizes waste of resources by reducing the parts to be discarded in reuse. In addition, the front slider inserted in the barrel is easily loaded and unloaded through the withdrawal grip portion provided in the front slider. Further, an action spring for elastically pushing the needle carrier in a frontward direction, and a rear end cap for supporting the actuation spring to be compressed to generate an elastic force are provided, so that the blood lancet device can perform blood collection based on the elastic force of the spring.

A disposable blood lancet device includes a barrel including a tubular barrel body; a tubular front slider inserted in the barrel; a carrier; a needle carrier; an actuation spring elastically pushing the needle carrier in the frontward direction; and a trigger portion coming into contact with the elastic transformation portion upon the rearward movement of the needle carrier and elastically transforming the elastic transformation portion inwards in the radial direction so that the interlocking holding projection can be separated inwards from the rear end of the front slider to propel the needle carrier frontwards.

An arrangement includes a housing, a plurality of sampling and analysis sites contained within the housing, each of the sampling and analysis sites having a skin-penetration member having a first end configured to pierce the skin, and an inner lumen in communication with the first end, an actuator operatively associated with the skin-penetration member, and an analyte quantification member in fluid communication with the inner lumen of the skin-penetration member. Integrated devices including such arrangements are also described.

An apparatus for obtaining and analyzing a blood sample is presented. The apparatus comprises an integrated drive unit having a common drive source and a drive force transmission gearing that couples a lancet drive, a device for advancing a magazine, and a sample transfer device to the drive source. A tensioning rotor and a drive rotor are mounted so that they are rotatable coaxially to one another. A first cam control converts the rotation of the drive rotor into a radial forward and reverse movement of a drive rod. A second cam control converts the rotational movement of the tensioning rotor into a linear movement of a link slide. A switching link moved by the link slide rotates the magazine an additional step. A third cam control converts the rotational movement of the tensioning rotor into a linear movement of a pressure tappet perpendicular to the piercing axis.
