Embodiment Construction

[0111] figure 1 The basic construction of the catheter 1 according to the invention is shown. It is assumed that, in the delivery state, the entire interior has already been prefilled with sterile saline and / or distilled water, whereby the catheter 1 can be used directly without degassing. The catheter 1 or also the other components forming the puncture system are supplied sterile packaged in the shown form and can be used immediately without further preparations after opening the outer packaging. Opening under sterile conditions is not required.

[0112] The catheter 1 has a patient-proximal end 10 at which a part of the catheter 1 is introduced into the patient's vein. The catheter 1 also has a patient-remote end 11 which, as can be seen, is arranged on an end region of the catheter 1 facing away from the patient-proximate end 10 . The catheter 1 is manipulated by the user at the end 11 remote from the patient.

[0113] The catheter 1 has a catheter tube 2 , a working lu...

Abstract

The invention relates to a puncturing system comprising an outer tubular body which is designed to remain in a body part of a living being, characterized in that the puncturing system has at least oneinner tubular body and a puncturing needle, wherein the inner tubular body is guided through a working lumen of the outer tubular body and can be longitudinally displaced with respect to the outer tubular body, and the puncturing needle is guided through a puncture lumen of the inner tubular body and the inner tubular body can be longitudinally displaced with respect to the puncturing needle, wherein, after a body part has been punctured by means of a puncturing section of the puncturing needle, which protrudes out of a patient-side end of the puncturing system, the inner tubular body can bemoved out of the patient-side end of the catheter at least partially out of the outer tubular body, and is thereby designed to accommodate the puncturing section of the puncturing needle, which protrudes out of the patient-side end of the catheter, at least partially in the puncture lumen of the inner tubular body.

Description

technical field [0001] The present invention relates to a puncture system with an outer tubular body configured to stay in a body part of a living being, for example to a central venous catheter with a catheter hose configured Used to stay in a vein. [0002] The invention also relates to an improved method for administering a puncture system, such as a central venous catheter, in particular with a puncture system, such as a central venous catheter, according to the invention, in view of the fact that the treatment method may achieve patent-protected jurisdiction. Background technique [0003] A central venous catheter is also known as a central venous catheter or central venous catheter or central venous access, or simply ZVK. [0004] Insertion of a central venous catheter is the most common medical procedure. The ZVK is a catheter that is introduced via a large, pierceable so-called "peripheral vein" not directly close to the heart and whose tip is located close to the ...
