Abstract

A catheter device ( 1 ) for providing access to a body cavity of a patient comprises a tube ( 10 ) and an inserting shell ( 11 ) arranged on the tube ( 10 ) and constituted to be fastened to an insertion guide ( 3 ) for inserting the catheter device ( 1 ) into a body opening (C) of a patient (P). Herein, the inserting shell ( 11 ) comprises an opening ( 111 ) into which a thread ( 300 ) of the insertion guide ( 3 ) is insertable for fastening the catheter device ( 1 ) to the insertion guide ( 3 ). In this way, a catheter device is provided which, in an easy and efficient manner, allows for the fastening to an insertion guide.

First claim

The invention claimed is:

1. A catheter device for providing access to a body cavity of a patient, comprising:
a tube, and
an inserting shell arranged on the tube and configured to be fastened to an insertion guide for inserting the catheter device into the body cavity of the patient,
wherein the inserting shell comprises an opening into which a thread of the insertion guide is insertable for fastening the catheter device to the insertion guide, and
wherein the inserting shell comprises a groove formed on an outer circumferential face of the inserting shell and extending around a circumference of the inserting shell, the groove configured to form a circumferential receptacle for the thread and to receive the thread therein, the thread forming a loophole placeable around the circumference of the inserting shell to extend around the outer circumferential face of the inserting shell.

2. The catheter device according to claim 1 , wherein from the opening a channel extends through the inserting shell towards a notch of the inserting shell, the thread being insertable through the channel to exit the channel at the notch.

3. The catheter device according to claim 1 , wherein the inserting shell has a conical shape, the opening being arranged at a tip of the inserting shell.

4. The catheter device according to claim 1 , wherein the inserting shell, at an end opposite the opening, comprises an insertion piece engaged with the tube and closing the tube at an end of the tube.

5. The catheter device according to claim 4 , wherein the insertion piece is bonded to the tube.

6. The catheter device according to claim 5 , wherein the insertion piece is glued or welded to the tube.

7. An arrangement, comprising a catheter device according to claim 1 and the insertion guide for inserting the catheter device into the body cavity of the patient, wherein the thread of the insertion guide forms a loophole placeable around the circumference of the inserting shell to extend around the outer circumferential face of the inserting shell.

8. The catheter device according to claim 1 , wherein the groove is configured to receive the thread without the thread protruding from the groove.

9. A method for fastening a catheter device to an insertion guide, the catheter device comprising a tube, and an inserting shell arranged on the tube and configured to be fastened to an insertion guide, the method comprising:
inserting a thread of the insertion guide into an opening of the inserting shell for fastening the catheter device to the insertion guide, and
placing a loophole formed from the thread around a circumference of the inserting shell to extend around an outer circumferential face of the inserting shell, the inserting shell comprising a groove formed on the outer circumferential face of the inserting shell and extending around the circumference of the inserting shell, the groove configured to form a circumferential receptacle for the thread and to receive the thread therein.
