Abstract

In a catheterization set for placing a catheter in a blood vessel, comprising a puncture needle (10) with a needle hub (16) carrying a grip device (25), a catheter (13) surrounding the puncture needle (10) and having a catheter hub (41) arranged thereon, and a guide wire (12) axially displaceable in the lumen of the puncture needle (10), it is provided, according to the invention, that a grip means (32) of the grip device (25) is arranged in spaced relationship beside the puncture needle (10). In this manner, the puncturing properties of the catheterization set are improved because the user can rest his hand performing the puncture in the immediate vicinity of the puncture site.

Claims

1. A catheterization set for placing a catheter in a blood vessel, comprising:

a puncture needle comprising a lumen and a needle hub carrying a grip device,

a catheter comprising a capillary tube and a catheter hub and being configured to surround the puncture needle,

an arm extending in a direction substantially parallel to the puncture needle from the needle hub to a location beyond the catheter hub,

grip means arranged on the arm at a location beyond the catheter hub and in spaced relationship with the puncture needle,

whereby the grip means overlays the capillary tube.

2. The catheterization set of claim 1, wherein the catheterization set defines a longitudinal axis and wherein the grip means comprises two mutually parallel grip plates extending substantially transversely to the longitudinal axis of the catheterization set.

3. A puncture instrument, comprising:

a needle having a longitudinal axis and an end provided with a hub,

an arm extending from the hub in a direction substantially parallel to the needle,

grip means arranged on the arm in spaced relationship with the needle,

the grip means comprising two mutually parallel grip plates extending substantially transversely to the longitudinal axis of the needle.
