Abstract

A device (2) for generating a vacuum for vacuum therapy of wounds has a facility for generating a vacuum and a vessel (10) for receiving wound exudates suctioned out of a wound. The vessel (10) can be detachably fastened to the device. A connection (12) is provided for a suction tube, the suction tube leading to the body to establish vacuum communication amoung the facility generating the vacuum, the vessel (10) and the suction tube. A holding facility (102) provides for detachable fastening of the device (2) onto a strut or bar and comprises an essentially rigid holding part (104), which can be attached to a housing (4) of the device and which has a receptacle (106) for detachable disposition of a flexible holding strap (108). The holding strap (108) can be wrapped around the strut or bar through application of a tensile force.

Claims

1. A device for generating vacuum for medical applications or for vacuum therapy of wounds on a human or animal body, the device comprising:

a housing;

a vacuum generator disposed in said housing;

a vessel for receiving body fluids or wound exudates suctioned out of a wound, said vessel structured for detachable fastening to said housing;

a connection element, said connection element structured for connection to a suction tube leading to the body, thereby establishing vacuum communication amoung said vacuum generator, said vessel and the suction tube; and

a holding facility for detachable fastening of the device onto a horizontal, vertical or oblique strut or bar, said holding facility comprising an essentially rigid holding part and at least one flexible or elastically compliant ribbon-shaped holding strap, said holding part structured for attachment to and detachment from said housing, said holding part having at least one receptacle for detachable disposition of said holding strap, said holding strap structured for placement around the strut or bar, said holding strap also being structured to turn back on itself or onto said holding part, wherein said holding strap is closed in response to exercise of a tensile force thereon, thereby generating a substantially clearance-free and clamped fastening of the device to the strut or bar.

2. The device of claim 1, wherein said essentially rigid holding part can be detachably fastened to said housing by means of a screw fastening, wherein, towards that end, a threaded hole is defined in said housing for acceptance of a threaded bolt.

3. The device of claim 1, wherein said essentially rigid holding part is made of a flat, thin material section.

4. The device of claim 1, wherein said receptacle for detachable disposition of said holding strap constitutes a sliding-seat configuration, wherein said holding strap is pushed onto said rigid holding part in a linear direction.

5. The device of claim 4, wherein said receptacle has at least one finger-shaped or tongue-shaped web or a flat web, which engages in a duct-forming cutout of said holding strap when said holding strap is pushed on.

6. The device of claim 1, wherein said receptacle is constituted in such a way that said holding strap can be fastened in two orientations of a longitudinal axis thereof that extend at 90°

to each other.

7. The device of claim 1, wherein said holding part has at least two receptacles, each for detachable disposition of one holding strap.

8. The device of claim 7, wherein said receptacles are oriented such that said holding straps are aligned at an angle of 90°

with respect to each other and with respect to the device.

9. The device of claim 1, wherein said holding part has an angular shape defining two legs.

10. The device of claim 9, wherein one receptacle for detachable disposition of one holding strap is constituted on each leg of said holding part.

11. The device of claim 1, wherein said holding strap has at least one duct-forming cutout.

12. The device of claim 11, wherein said holding strap has two mutually perpendicular duct-forming cutouts.

13. The device of claim 1, wherein said holding strap has a mechanical-action closing element, said closing element being turned back on itself or onto said holding part for closure thereof.

14. The device of claim 13, wherein said mechanical-action closing element is constituted by at least one projection on one side and by through-holes on an other side.

15. The device of claim 14, wherein said at least one projection extends in a plane of said holding strap or in a plane of said holding part.

16. The device of claim 14, wherein said holding strap has a reinforcing part constituted as a rigid or injection molded part.

17. The device of claim 16, wherein said reinforcing part defines said at least one projection.

18. The device of claim 1, wherein said holding strap has a thicker region that is constituted with 3-dimensional contouring in a transverse direction with respect to a ribbon plane, to form a compliant contact zone for contacting the bar or strut.

19. The device of claim 1, wherein said holding part is constituted in such a way that said vessel for receiving liquids is disposed between said receptacle of said holding part and said housing.

20. The device of claim 1, wherein said holding facility and said holding part are constituted in such a way that variously dimensioned vessels are removable from said housing or mountable to said housing without any need to detach said holding facility.
