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.

A standalone safety device for a needle of a medical device A safety device for a needle of a medical device, the safety device including: a ring fixed with regard to the needle, a shield mounted on the ring by a pivot link, a protective cap covering at least partially the needle in an initial configuration, a translation locking unit adapted to prevent a translation movement of the protective cap, and a rotation locking unit adapted to prevent a rotation movement of the shield with regard to the ring. The translation locking unit is configured to be disengaged by the application of a predetermined translation force on the protective cap. The rotation locking unit is configured to be disengaged during a portion of the translation movement of the protective cap with regard to the shield.

Embodiments of the present invention provide magnetic lancet devices and methods for driving a lancet. For example, a magnetic lancet device may include a driving mechanism having a plurality of magnets and a lancet coupled to the driving mechanism. A magnetic interaction between the plurality of magnets is configured to drive the lancet from an engaged position to a penetrating position.

An ejection-type safety intravenous needle includes a sheath, a hub, a cannula fixed on the hub, and a base. An accommodation cavity is formed in the base. The hub is fixed in the accommodation cavity, and the cannula is exposed outside of the accommodation cavity. The sheath encloses the cannula, and a bottom of the sheath is located in the accommodation cavity and provided with a first limiting structure. A second limiting structure cooperating with the first limiting structure is provided at a top of the accommodation cavity. An elastic element is provided in the accommodation cavity, and the elastic element abuts against a bottom end of the sheath. A top and a bottom of the base are provided with a first clamping structure and a second clamping structure, respectively. A third clamping structure cooperating with the first clamping structure and the second clamping structure is provided on the sheath.

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 blood draw device including an introducer and an actuator. The introducer has a proximal end portion, a distal end portion, and an inner volume, and includes a top surface having a first portion of a first length and a second portion of a second length. The first portion may have a smooth surface along the first length and the second portion has a plurality of ridges along the second length. The actuator includes an exterior portion positioned above the top surface and an interior portion positioned within the inner volume, wherein the exterior portion of the actuator includes an engagement member and a downwardly-extending tab projecting below the engagement member such that the downwardly-extending tab of the actuator may contact at least the plurality of ridges of the second portion of the introducer to provide at least one of tactile and audible feedback to a user.

A retractable needle assembly includes a housing having a sidewall defining a hollow bore, and an elongate plunger, the distal end of the plunger forming a reservoir within the hollow bore for containing a fluid therein. The plunger is adapted for slideable movement within the hollow bore. The assembly includes a hub disposed within the hollow bore and at least partially supporting a cannula therewith, and a needle retraction member engaged with the hub for manually selectable advancement with respect to a portion of the housing. The needle retraction member may be advanced from an initial position in which at least a portion of the needle is disposed outside the housing, to a retracted position in which the needle is fully surrounded by the housing. The elongate plunger may be advanced about the hub for extracting the fluid into the reservoir or expelling the fluid from the reservoir.

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.
