Insertion aid

1. Device for inserting a tracheostomy tube, comprising a guide element and a dilator, wherein the dilator is tubular and the guide element can be introduced into the dilator at least in sections, wherein the guide element is directly in contact with a shield, said shield having a tip and a shield wall and a base, wherein the guide element passes along an axis of the shield and of the tip of the shield, and the shield in the area of the tip is securely connected to the guide element and wherein the shield has a first and a second state and wherein the shield in the first state has a conical shape and in the second state is deformed compared with this conical shape, characterized in that the guide element has a first securing means and the dilator has a corresponding second securing means, whereby the guide element can be detachably connected by positive locking to the dilator in a position in which a distal end of the dilator is engaged with an inner surface of the shield when the shield is in the first state.

2. Device according to claim 1 , characterized in that, at the base of the shield, the shield in the first state has an outside diameter which is larger than the inside diameter at a distal end of the tracheostomy tube to be inserted with the device, and wherein the shield in the second state of the shield has a smaller outside diameter than the inside diameter of the tracheostomy tube to be inserted with the device due to deformation.

3. Device according to claim 2 , characterized in that, at the base of the shield, the shield in the first state has an outside diameter that corresponds to the outside diameter at the distal end of the tracheostomy tube to be inserted with the device.

4. Device according to claim 1 , characterized in that the second securing means is located on the dilator at the distal end and the first securing means is located on the guide element in an area which, in an unconnected state of the first and second securing means, in the first state of the shield is completely covered by the shield and in the second state of the shield is not completely covered by the shield.

5. Device according to claim 1 , characterized in that the first securing means and the second securing means form a turn-lock fastener.

6. Device according to claim 5 , characterized in that the first securing means and the second securing means form a threaded fastener or a bayonet fastener.

7. Device according to claim 1 , characterized in that the first securing means and the second securing means form a detent connection.

8. Device according to claim 1 , characterized in that the inner surface of the shield has a grooved structure and the dilator has a corresponding grooved structure at the distal end, wherein the grooves of the grooved structure extend in the longitudinal direction.

9. Device according to claim 1 , characterized in that the inner surface of the shield lies against against the distal end of the dilator in a connected state of the first and second securing means, and in the first state of the shield with an elastic pretension.

10. Tracheostomy tube, having a cannula tube with a proximal end and a distal end, with a device according to claim 1 .

11. Tracheostomy tube according to claim 10 , characterized in that the dilator in the area of the proximal end of the dilator has a third securing means, with which the dilator can be detachably connected to the proximal end of the cannula tube or to a fourth securing means at the proximal end of the cannula tube.

12. Tracheostomy tube according to claim 11 , characterized in that the third securing means comprises a union nut or a clamp or a connector.
