Problems solved by technology

However, visual control of the amount of blood that should be drawn may not be sufficient as the handle and / or the phlebotomist's fingers in such a small lancing device greatly restrict the view to the bleeding port and may even completely block it
In addition, the laterally curved bleeding port results in the cannula enabling optimal bleeding only in one position of use
In addition to the laborious production of curved, laterally bent needle tubes, there is also the disadvantage that the higher flow resistance of the needle tube due to the curvature impedes the flow of the blood that would otherwise be drawn only in small quantities

Embodiment Construction

[0011] The lancing device 1 shown in the figure has a hollow needle or needle tube 3 arranged in a holder 2 . For puncturing into a vein, the hollow needle is provided at its front end with a sharpened needle point 4 as a blood inlet port and at its opposite proximal end with a bleeding port 5 . The bleeding opening 5 is arranged in the large free space provided by a bow-shaped bridging element 6 . The bridging element connects the needle holder 2 to the handle area 7 of the lancing device 1 .

[0012] When the needle tube 3 penetrates the vein with its needle point 4, the straddling bridging element 6 allows the lancing device to be rotated without problems and provides a large, unobstructed viewing area for the operator and enables Using a large receiving container and the ability to see the first drop of blood immediately allows even the smallest amount of blood to be collected without loss.

Abstract

The instrument (1) to take blood samples from newborn infants, and small children, has a hollow needle (3) in a holder (2) with a sharp point (4) to penetrate a vein and take blood. A stirrup-shaped bridge (6), over the blood outflow (5), links the handle (7) with the needle holder.

Description

technical field [0001] The invention relates to a blood sampling device for newborns and children, which comprises a needle tube provided with a blood inlet and a blood outlet, and arranged in a bracket with a handle. Background technique [0002] DE 100 60 302 A1 discloses such a device for drawing venous blood in neonates or premature infants, infants and children. A hollow needle or needle tube formed at its distal end with a sharpened tip has at its proximal end a hemorrhage curved laterally toward its longitudinal axis and rests on a support with its hemorrhage The handle area at the rear offers a possibility to hold or control it. During blood collection, a container for receiving outflowing blood is supported below the bleeding port of the needle tube. [0003] Unlike traditionally used injection needles, the needle tube of this blood collection device no longer needs special preparation, such as breaking off the usual Luer-cone, which reduces the risk of infection ...
