Improvements in and relating to blood sampling devices 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 its fire position is blocked and an intermediate position in which the trigger mechanism may be moved to its fire position. The intermediate position is obtainable only on removal of the safety cap.

An integrated testing device and fluid module are disclosed, as well as a method of manufacture. Fluid module contains a reservoir containing a test fluid, and a control vessel. The reservoir discharges test fluid into the control vessel, which discharges the test fluid in a controlled way to a test component.

A lancet device generally includes a housing having opposing lateral sides extending between a forward end and a rearward end, and a shield coaxially and movably associated with the housing. The housing includes a plurality of longitudinal ribs extending along a portion of at least one of the opposing lateral sides. The plurality of longitudinal ribs form a finger grip on at least one of, and typically both of the opposing lateral sides. The shield is generally movable from a first position in which the shield extends outwardly from the forward end of the housing to a second position in which the shield is at least partially moved within the housing, based on axial pressure applied by the user against the finger grip formed by the longitudinal ribs.

The present invention includes a system for withdrawing body fluids. The system includes a drive unit having a plunger which is moved from a resting position into a lancing position in order to carry out a lancing process and a lancing unit containing a lancet with a needle. The plunger and lancet are coupled together by a form fit in order to carry out a lancing process. The invention additionally concerns a method for temporarily extending a needle from a device for withdrawing body fluid as well as a lancing unit that can be attached to the drive unit.

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.

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.

A one-time/single use safety lancet system includes a body; a spring coupled to the body; a keeper having a deformable member; and a core for supporting a lancet and having an end coupled to the spring. The core further has a first latch for engaging the deformable member when the lancet system is in an armed state. The deformable member of the keeper is fractured after one use of the lancet system which prevents any subsequent arming of the lancet system. The keeper may be made part of the lancet body. The core may include a second latch, wherein the second latch permanently deforms or fractures the deformable member of the keeper after the single, one-time arming of the safety lancet system.

A disposable lancing device contains: a first casing, a second casing, and a needle holder. The first casing includes a close segment, an open segment, a slideway, two tilted contact faces, a fixing portion, two recesses, and two push fringes. The second casing includes an accommodation chamber, two limitation extensions, and multiple drive protrusions. A forcing face is defined on the second casing opposite to the two limitation extensions, and a through hole is defined on a center of the forcing face. The through hole has a protruded rib. The needle holder includes a collection needle having a syringe needle, and the needle holder further includes a trigger spring, a return spring, and two symmetrical flexible wings. The two symmetrical flexible wings include two driving segments configured to abut against the two symmetrical flexible wings to flexibly retract inward by using the two tilted contact faces.

An assembly for sampling bodily fluid, the assembly comprising a membrane penetration device comprising a membrane penetrating element for penetrating a bodily membrane to release a bodily fluid; and, a collector configured in a collection position to take up the released bodily fluid and retain the fluid for delivery to a test element.

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.
