Devices and methods for withdrawing bodily fluid from a patient are disclosed herein. In some embodiments, a handheld device can include a housing having an opening, and a skin-piercing assembly and a plunger positioned at least partially within the housing. The skin-piercing assembly can include a blade and a biasing member, such as a torsion spring. The plunger can be movable relative to the housing from a first position to a second position. In the first position, the plunger can engage the skin-piercing assembly to maintain the biasing member in a biased configuration. Movement of the plunger from the first position to the second position can disengage the plunger from the skin-piercing assembly to permit the first biasing member to drive the blade through and/or across the opening in the base.

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.

A biological fluid sampling transfer device adapted to receive a multi-component blood sample is disclosed. After collecting the blood sample, the biological fluid sampling transfer device is able to separate a plasma portion from a cellular portion. After separation, the biological fluid sampling transfer device is able to transfer the plasma portion of the blood sample to a point-of-care testing device. The biological fluid sampling transfer device also provides a closed sampling 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 sampling transfer device is engageable with a blood testing device for closed transfer of a portion of the plasma portion from the biological fluid sampling transfer 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.

A biological fluid collection device that is adapted to receive a blood sample having a cellular portion and a plasma portion is disclosed. After collecting the blood sample, the biological fluid collection device is able to transfer the blood sample to a point-of-care testing device or a biological fluid separation and testing device. After transferring the blood sample, the biological fluid separation and testing device is able to separate the plasma portion from the cellular portion and analyze the blood sample and obtain test results.

There is provided an injector having an improvement in a linear launching profile. The injector of the present invention is used for launching a lancet to provide a pricking. The injector of the present invention comprises a plunger capable of launching the lancet in a pricking direction, an injector housing which surrounds the plunger, and an injector cap capable of being attached and detached with respect to the injector housing. In particular, an inner face of the injector cap is provided with a rib, and the rib and the plunger moving for the pricking are capable of contacting with each other.

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.
