In one embodiment, a blood withdrawal system for withdrawing blood for diagnostic purposes includes a base device configured to hold a structurally distinct lancet. The base device includes an actuatable lancet ejection mechanism for ejecting the lancet from the base device, and the lancet ejection mechanism includes a movable coupling element. The coupling element includes a coupling structure for coupling the lancet with an external component via the coupling element and subsequently activating the lancet ejection mechanism by operating the external component.

The present disclosure relates to a blood collection device, including: a shell; a blade seat, arranged in the shell; an elastic component for providing an elastic force for pivoting the blade seat; a triggering portion, including an operating end and an abutting end, wherein the triggering portion has a first position and a second position for pivoting, the operating end extends to the outside of the shell, the abutting end is located in the shell, based on the operation of the operating end, the triggering portion is suitable for pivoting from the first position that prevents the blade seat from pivoting to the second position that allows the blade seat to pivot based on the elastic force of the elastic component, wherein: a cooperation column is arranged in the shell and is located at the upper side of the triggering portion spaced from the triggering portion; and an elastic arm is connected to the upper side of the triggering portion, the end part of the elastic arm includes a blocking portion, the end part of the elastic arm is suitable for being located on one side of the cooperation column when the triggering portion is at the first position, and is located on the other side of the cooperation column when the triggering portion pivots from the first position to the second position, and the blocking portion provides resistance for the end part of the elastic arm while moving from one side of the cooperation column to the other side.

An arrangement for producing a sample of body fluid from a wound opening created in a skin surface at a sampling site includes: a housing, the housing comprising a first opening; a skin interface member disposed in the first opening, the skin interface member comprising an inner member having a second opening, and an outer member at least partially surrounding the inner member and attached to the first opening; and at least one skin-penetration member configured and arranged to project within the second opening. Arrangements having alternatively constructed skin interface members are also described.

A lancing device for infant with safety rotating and unlocking push-shooting button is provided. The push-shooting button is exposed and occupies two position attitudes. A first attitude is an insurance lock-out state that the push-shooting button is locked to avoid an undesired trigger before actuation, and a second attitude is a state that leaves away from the first one attitude where the push-shooting button is readily loaded to be launched. Under the insurance lock-out state, the push-shooting button is locked and moves only by a rotation. Firstly, the button is rotated and loaded to a to-be-launch state. Then, the button is pressed inwards and an edge lancing mechanism is actuated with a blade projecting from a lancing opening of the shell to cut and retract back into the shell. The whole blood collecting procedure is finished.

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 system for extracting and collecting a sample of a fluid of a user, comprising a sample collection device, comprising a sample container arranged to receive said sample; a cap arranged to cooperate with the sample container and having an incision mechanism movable in the cap by a triggering mechanism; a sealing mechanism; a sample extraction device, comprising a vacuum creation mechanism arranged to create vacuum in a vacuum chamber; and a valve control mechanism arranged to release the vacuum from the vacuum chamber to the sample collection device. The system simplifies collection of a fluid (e.g., blood) sample while keeping a high-quality standard for its analysis, minimizes the risk of injury due to handling the sample, reduces the risk of contamination of the collected sample, is compatible with standard blood analysers of central laboratories, requires minimal action from the user, and can collect large volumes of bodily fluid.

The present invention generally relates to devices and techniques associated with diagnostics, therapies, and other applications, including skin-associated applications, for example, devices for delivering and/or withdrawing fluid from subjects, e.g., through the skin. In some embodiments, the device includes a system for accessing an extractable medium from and/or through the skin of the subject at an access site, and a pressure regulator supported by a support structure, able to create a pressure differential across the skin at at least a portion of the access site. The device may also include, in some cases, a sensor supported by the support structure for determining at least one condition of the extractable medium from the subject, and optionally a signal generator supported by the support structure for generating a signal relating to the condition of the medium determined by the sensor.

An infant peripheral lancing device having safety buckle turn lock and anti-backward push button, wherein the safety mechanism is a safety buckle rotationally connected on a housing, and the first occupation gesture of the safety buckle during movement is between a push button and the housing and locks the push button; the second occupation gesture is in unlocking position. The push button is set with a locking mechanism, which comprises a first locking part on the push button and a second locking part on the housing or the cam and when the push button is moved backward, the first locking part and the second locking part meet to form a locking state. This solution always connects the safety buckle and the housing to prevent an accidental disconnection or loss and the lancing device present invention locks the push button automatically after using to make it easy for the user to identify the state of the push button.

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.
