Puncture device with a flexible catheter tube for connecting to a medical infusion line
First Claim
1. A puncture device comprising a flexible catheter tube for connecting to a medical infusion line having a catheter hub attachable at a puncture site on the skin surface of a patient, and having a connector for connecting the infusion line and an outlet for the flexible catheter tube, and a needle holder having a puncture needle, wherein the flexible catheter tube is arranged in an interior of the catheter hub and extends out through the outlet with its output end, wherein the end of the flexible catheter tube opposite the output end is located in the interior of the catheter hub in the area of the connector and separated from the surrounding area by a septum, and wherein the needle holder securely fastens the puncture needle insertable into a passage channel of the catheter tube at the end opposite the pointed or sharp puncture tip, and is detachably arranged at the connector in a starting position of the puncture device such that the puncture needle penetrates the septum and is guided in the passage channel of the catheter tube beyond the output end, wherein the outlet is arranged on a bottom side of the catheter hub resting on the patient surface in the position of use, and in wherein the puncture needle is made without a duct.

Abstract
A puncture device with a flexible catheter tube for connecting to a medical infusion line, wherein the device includes a catheter connecting piece or hub attachable at the puncture site on the skin surface of a patient, wherein the catheter hub has a connector for connecting the infusion line and an outlet for the flexible catheter tube; and a needle holder having a puncture needle (stylet), wherein the flexible catheter tube is arranged in the interior of the catheter hub and extends out of the outlet with an output end. The end of the flexible catheter tube opposing the output end is located in the interior of the catheter hub in the area of the connector and is separated from the surrounding area by a septum, wherein the needle holder securely fastens the puncture needle insertable into a passage channel of the catheter tube at the end opposing the pointed or sharp puncture tip. The outlet is located at the bottom side of the catheter hub resting on the surface of the patient in the position of use and the puncture needle is made without a duct.
