Abstract

A device for preventing infections during introduction of a fluid into a body, has an element which is formed so as to surround an introducer over its periphery and extend over a part of its elongation, so that when the introducer is introduced through an opening into the body the element completely covers an area of the opening, the element being composed of a material which is biocompatible and does not cause growth of germs, bacteria, and the like.

Claims

1. A device for preventing infections during introduction of a fluid into a body, comprising an element which is formed so as to surround an introducer over its periphery and extend over a part of its elongation, so that when the introducer is introduced through an opening into the body the element completely covers an area of the opening, said element being composed of a material which is biocompatible and does not cause growth of germs, bacteria, and the like, said element having a core composed of another material and a coating composed of said first mentioned material.

2. A device as defined in claim 1, wherein said element is disk shaped and has a central hole with which it is fittable on the introducer.

3. A device as defined in claim 1, wherein said element is sleeve-shaped and has a sleeve portion and a disk portion.

4. An introducer for introducing fluids into a body, comprising an introducing part with which a fluid can be introduced into the body;

and a device for preventing infections associated with said introducing part, said device including an element which is formed so as to surround said introducing part over its periphery and extend over a part of its elongation, so that when said introducing part is introduced through an opening into the body the element completely covers an area of the opening, said element being composed of a material which is biocompatible and does not cause growth of germs, bacteria, and the like, said element having a core composed of another material and a coating composed of said first mentioned material.

5. An introducer as defined in claim 4, wherein said element is disk shaped and has a central hole with which it is fittable on the introducer.

6. An introducer as defined in claim 4, wherein said material is a mixture of high-molecular polyphosphazens consisting of poly-[bis-(trifluoroetoxy)phosphazens] with a molecular mass 1-1.5 million and molecular mass 1.5-2.7 million in a quantitative ratio correspondingly (0.15.0):

(95.0-99.0).

7. An introducer as defined in claim 4, wherein said element is sleeve-shaped and has a sleeve portion and a disk portion.

8. A device for preventing infections during introduction of a fluid into a body, comprising an element which is formed so as to surround an introducer over its periphery and extend over a part of its elongation, so that when the introducer is introduced through an opening into the body the element completely covers an area of the opening, said element being composed of a material which is biocompatible and does not cause growth of germs, bacteria, and the like, said element having a projection extending in an axial direction and having a diameter reducing from an outer diameter of said projection in an introducing direction.

9. An introducer for introducing fluids into a body, comprising an introducing part with which a fluid can be introduced into the body;

and a device for preventing infections associated with said introducing part, said device including an element which is formed so as to surround said introducing part over its periphery and extend over a part of its elongation, so that when said introducing part is introduced through an opening into the body the element completely covers an area of the opening, said element being composed of a material which is biocompatible and does not cause growth of germs, bacteria, and the like, said element having a projection extending in an axial direction and having a diameter reducing from an outer diameter of said projection to an outer diameter of said introducing part in an introducing direction.

10. An introducer for introducing fluids into a body, comprising an introducing part with which a fluid can be introduced into the body;

and a device for preventing infections associated with said introducing part, said device including an element which is formed so as to surround said introducing part over its periphery and extend over a part of its elongation, so that when said introducing part is introduced through an opening into the body the element completely covers an area of the opening, said element being composed of a material which is biocompatible and does not cause growth of germs, bacteria, and the like, said element being formed integral of one piece with said introducing part.
