A lancing device including a latch that pivots between a non-blocking position allowing a lancet carrier and a lancet to advance and retract through a first forward and reverse lancing stroke and a blocking position preventing further/excess/secondary oscillation of the lancet carrier and lancet. The pivotal latch can pivot about an axis perpendicular (e.g., for an L-shaped latch) or parallel/coaxial (e.g., for a sleeve latch) to the advancement and retraction motion of the lancet carrier and lancet.

A needle assembly can include a needle and a proximal compartment forming a reservoir for collecting blood that flows through an inner lumen of needle. The needle assembly may also include a needle tip shield for capturing a sharpened distal tip of the needle. The needle tip shield can form a fluid pathway through which blood contained within the reservoir is expelled. The volume of the reservoir can be reduced to cause blood to be expelled from the needle tip shield such as by compressing the proximal compartment or a plunger connected to the proximal compartment or by moving a plunger into the reservoir. The fluid pathway of the needle tip shield can either be the same pathway through which the sharpened distal tip is withdrawn into the needle tip shield, or can be a separate pathway.

The present application concerns a system for the withdrawal of body fluids comprising a coupled tensioning and triggering mechanism, wherein the triggering mechanism is mechanically coupled to the tensioning mechanism in such a manner that the puncturing process is automatically triggered by successive continuation of the tensioning movement when the tensioning mechanism is actuated and wherein the lancing process triggered in this manner is carried out by a lancet.

Devices are provided to automatically inject drugs or other payloads into or beneath skin. These devices include an injector configured to drive a hollow needle into the skin and subsequently to deliver the payload through the hollow needle. Applied suction acts to draw blood from the puncture formed in the skin through the hollow needle, into the device, and to a sensor, blood storage element, or other payload. In some examples, the blood is drawn through the hollow needle when the hollow needle is penetrating the skin. In some examples, these devices are additionally configured to retract the hollow needle from the skin and/or to perform some other functions. These devices can be wearable and configured to automatically access blood or deliver a payload into skin, for example, to operate at one or more points in time while a wearer of a device is sleeping.

Arrangements are provided including a base having a bore disposed therein extending from a first surface of the base through a second surface of the base, a fluid transport tube having a first end, a second end opposite the first end, and a lumen having an inner diameter, at least the second end of the tube being received within the bore of the base, and at least one fluid transport enhancing groove having at least a first section disposed in the second surface of the base and in fluid communication with the bore.

A device that permits collection of blood from a patient by a needle and also places a catheter tube in the circulatory system of the patient.

A medicine injection device includes a header including a first connector configured to receive an electrical signal associated with a target analyte from a needle and configured to be connected to the needle, a medicine storage configured to be connected to the needle when the needle and the header are connected and store a medicine, a driver configured to apply an external force to the medicine storage, a controller configured to control the driver to measure an amount of the target analyte based on the received electrical signal, determine an injection amount in response to the measuring being completed, and inject the determined injection amount, and a notifier configured to receive, from the controller, measurement information associated with the amount of the target analyte and injection information associated with the injection amount and provide a user with the received measurement information and injection information.

When drawing blood, it is useful to always have the needle in a bevel up position but this cannot be guaranteed using conventional syringe barrel/needle assemblies. This problem is solved by providing a needle holder having a proximal end and a distal end, the proximal end being provided with means adapted to secure an integral screw-threaded hub of a needle or a double ended needle, wherein the means comprises a circular wall defining a bore through the proximal end of the needle holder, the wall incorporating a pair of opposed helical ledges, the path of each respective ledge spanning up to half the circumference of the bore, the incline of each ledge being so arranged on the wall as to permit complementary mating contact with a screw-threaded hub of a needle or a double ended needle.

A segmented safety cover may include a proximal segment combined with a needle hub; a needle cannula that extends from the proximal needle hub to a distal sharpened end; a distal end cap with a hollow bore through which the needle cannula passes; a centrally mounted toggle locking mechanism, separating the proximal needle hub from the distal end cap; the toggle locking mechanism is torsion spring assisted; a proximal cover segment is connected to the hub via a proximal hinge and a distal cover segment is connected to the end cap via a distal hinge; said proximal cover segment and said distal cover segment of said toggle locking mechanism being configured with abutting faces when the segmented safety cover is in a safety mode; and wherein the proximal hinge, abutting faces and distal hinge are in line in the safe mode.

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.
