Abstract

The curved safe injection needle / cannula to avoid further injury is characterized that an offset to preferably 10-20 mm after the needle tip allowing precise control of the penetration depth.

Description

  • Normally, a straight cannula or injection needle ( 1 ) into the skin ( 1 ) and then into the vein ( 2 ), often puncturing the vein, or injuring the opposite side of the vein, because the practitioner does not know how far the needle has been pierced.
  • There is a significant curvature in the new cannula / injection needle ( 2 ), or displacement of the needle tip after preferably 10-20 mm instead, whereby a constant accurate control of the penetration depth is given.
  • Because in my development, the tip of the cannula blade is at the top ( 3 ), the wound is automatically closed after pulling out the needle like a valve ( 3 ), so that blood can expect to lose less blood afterwards. After the tip of the needle (the upper tip of the upper incision), after 10-20 mm (this should be sufficient for a secure fit in the vein or vein!), The needle should be displaced by approx. 3.5 mm (0.5-1 mm vein wall thickness and 2 mm 3 mm of skin plus one needle size), although there are also different dimensions for the different applications.
  • Only by this offset ( 2 ) (The offset should correspond as far as possible to an international standard, which however still has to be fixed!) A more precise grooving is possible because the treating person can see the exact penetration depth at any time! Since this offset occurs in slightly curved arches and in the middle at an angle below 45 °, the piercing force is not significantly weakened, so that you can continue working with the normal cannula strength.
  • Since the needle is slightly swung in the direction of cores after the puncture of the anterior wall by the person being treated, the cutting edge of the hypodermic needle, the anterior tip of which now lies opposite the posterior corpuscles, now glides on the opposite wall of the corpus without injuring or penetrating it. You could now bend the entire top slightly more safely, to be even more secure ( 4a )! In order to avoid injuries on the insertion side as well, you can now chamfer the upper tip of the piercing point very thinly back to the upper side ( 4 ) or round off (about half the wall thickness of the cannula / injection needle).
  • In order to compensate for differences in skin thickness and vein wall thickness when fixing the cannula, the cannula or injection needle is slightly rotated until the rear part of the cannula lies on the skin and can be easily fixed with adhesive plaster / adhesive strips ( 5 ). A cone attached to the end of the cannula (transition from cannula / injection needle to adapter for the hose connection, etc.) with pressure attachment ( 9 ) with a corresponding counterpart with a flat one- or two-sided wing ( 8th ), which is then pressed after the fixation of the cannula / injection needle on the skin on the cone, can, inter alia, with a rotating device of the hose connection ( 9 ), also injuries due to relaxation rotational movements of the hose ( 10 ) prevent.
  • In order to is it possible for the first time a needle or cannula to put, without further additional Cause injury.

Claims (9)

  1. The curved safe injection needle / cannula to avoid further injury is characterized in that an offset of preferably 10-20 mm after the needle tip allows precise control of the penetration depth.
  2. characterized in that the foremost cutting tip the injection tip now by an offset of the longitudinal axis the cannula / injection needle now can be accurately positioned and preferably in the same Direction points.
  3. characterized in that the offset of the middle skin thickness (1-3 mm), and the average vein strength (0.5-1.5 mm) and the cannula or injection needle strength corresponds, so the injection needle, or cannula in the vein, or vein free and rests on the skin.
  4. characterized in that the offset in a Angle as possible below 45 degrees, and through a for the injection needle or cannula gentle curvature he follows.
  5. characterized in that the cutting tip above, a slight skew or rounding to the rear, which is preferably half the wall thickness of cannula or injection needle amounts.
  6. characterized in that a cone at the end of cannula or injection needle is provided with a small pressure pin, on the other hand has a counterpart, with one or both sides wing-like surfaces is provided, which stick when pressed together and on the skin rest. As a result, the wings need to rest on the skin, they are outside the cannulae or injection needle axis offset in the direction of the skin.
  7. characterized in that the Flügelarti conditions on one or both sides are provided with an adhesive device which fixes the cannula / injection needle after a short pressure.
  8. characterized in that after the cannula, or Hypodermic needle consists of a movable connector that turns of the subsequent Hose or other components / device / connection allows.
  9. characterized in that the tip of the injection needle / cannula (After the cutting edge a few millimeters.) slightly bent upwards is.
