A blood lancet device comprising a housing having one end formed as an opening; a sliding sleeve having one end extending from the opening to the outside of the housing; a blood lancet including a needle body and a needle tip arranged at one end of the needle body, the sliding sleeve being bushed at the outside of the housing, said blood lancet adapted to move relative to the sliding sleeve so as to expose the needle tip at the opening; and a biasing member having one end securely fixed with another end of needle body.

Various collection devices, systems and methods relating to the use of devices with open microfluidic channels disposed within a housing defining a lumen. These devices make use of microneedles passed through apertures to induce fluid flow into microfluidic channel networks for collection and analysis. The device can be actuated via button when placed on the skin of a patient to collect a fluid sample, such as a blood draw.

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.

An apparatus and a method for measuring a property of a blood sample is shown. The apparatus comprises of a housing having an aperture; a shaft mounted inside the housing; a testing member rotatably mounted on the shaft; an actuating member coupled to the housing and configured to exert a force against the testing member; and a lancet for eliciting a blood sample fixedly coupled to and protruding substantially radially from the testing member and configured to co-rotate with the testing member. The apparatus is further configured such that the lancet is aligned with the aperture in the housing when the testing member is in a first position. The testing member is configured, in the presence of a force exerted against the testing member by the actuator member, to translate to a second position in which the lancet is in a skin penetrating position.

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.

Systems, methods, and kits are disclosed for collection, labeling and analyzing biological samples containing nucleic acid in conjunction with collecting at least one ridge and valley signature of an individual. Such devices and methods are used in forensic, human identification, access control and screening technologies to rapidly process an individual's identity or determine the identity of an individual.

A tissue penetrating system has a housing member, a plurality of penetrating members positioned in the housing member and a plurality of sample chambers. Each sample chamber is associated with a penetrating member. A tissue stabilizing member has a tissue interface surface configured to be applied to a tissue surface and provide for spontaneous flow of blood for sample capture. The tissue stabilizing member is coupled to the housing.

A blood sampling device includes a housing and a lancet supporting a lancet needle or tip, the lancet and needle being urged or urgeable in a pricking direction. A trigger mechanism is moveable to a fire position for releasing the lancet to travel in the pricking direction. A removable safety cap initially covers the lancet needle. The lancet has an initial position in which movement of the trigger mechanism to the fire position is blocked and an intermediate position in which the trigger mechanism may be moved to the fire position. The intermediate position is obtainable only on removal of the safety cap.

The present invention generally relates to systems and methods for receiving blood (or other bodily fluids) from a subject, e.g., from or beneath the skin of a subject. In some cases, the blood (or other bodily fluids) may be deposited on a membrane or other substrate. For example, blood may be absorbed in a substrate, and dried in some cases to produce a dried blood spot. In one aspect, the present invention is generally directed to devices and methods for receiving blood from a subject, e.g., from the skin, using devices including a substance transfer component (which may contain, for example, one or more microneedles), and directing the blood on a substrate, e.g., for absorbing blood. The substrate, in some embodiments, may comprise filter paper or cotton-based paper. After absorption of some blood onto the substrate, the substrate may be removed from the device and shipped or analyzed. In some cases, the device itself may be shipped or analyzed. For example, in some embodiments, a portion of the device may be sealed such that the substrate is contained within an airtight portion of the device, optionally containing desiccant. Other aspects are generally directed at other devices for receiving blood (or other bodily fluids), kits involving such devices, methods of making such devices, methods of using such devices, and the like.
