Bellows for coupling a source acoustic waves to a subject to be treated
A bellows for coupling a source of acoustic waves having an acoustic propagation medium, to a patient, has a geometrical modification in that region wherein the bellows can be seated against the patient for the introduction of acoustic waves into the patient. The geometrical modification in the propagation path of the acoustic waves generated by the source of acoustic waves shapes the acoustic waves in a designated (designed) manner. Additionally or alternatively, the bellows can have a section in the region that is formed of a different material than the rest of the bellows.
1. A bellows for coupling a source of acoustic waves, containing an acoustic propagation medium, to a treatment patient, said bellows comprising:
a bellows element configured to be seated against a treatment patient for introducing said acoustic waves into said treatment patient, said bellows element having an exterior and an interior and having an interior side facing away from said treatment patient; and
a geometric element firmly attached directly to said interior side of said bellows element, said geometrical element being disposed in a propagation path of said acoustic waves and shaping said acoustic waves in a designed manner to provide therapy to the patient.
2. A bellows as claimed in claim 1 wherein said geometrical element comprises an acoustic mirror.
3. A bellows as claimed in claim 2 wherein said acoustic mirror is a planar mirror.
4. A bellows as claimed in claim 2 wherein said acoustic mirror is a conical mirror.
5. A bellows as claimed in claim 2 wherein said acoustic mirror comprises at least two inclined mirror faces.
6. A bellows as claimed in claim 1 wherein said element comprises a plurality of regularly arranged objects.
7. A bellows as claimed in claim 1 wherein said element comprises a plurality of irregularly arranged objects.
8. A bellows as claimed in claim 1 wherein said element comprises an acoustic filter.
9. A bellows as claimed in claim 8 wherein said acoustic filter is a filter selected from the group consisting of high-pass filters and low-pass filters.
10. A bellows as claimed in claim 1 wherein said element comprises an acoustic lens.
11. A bellows as claimed in claim 1 wherein said element comprises an acoustic wave absorber.
12. A bellows as claimed in claim 1 comprising a bellows wall containing said region, said bellows wall and said element being comprised of the same material.
13. A bellows as claimed in claim 1 comprising a bellows wall in which said region is disposed, said bellows wall and said element respectively being comprised of different materials, each of said different materials having acoustic properties that differ from acoustic properties of said acoustic propagation medium.
14. A bellows for coupling a source of acoustic waves, containing an acoustic propagation medium, to a treatment patient, said bellows comprising:
a bellows wall having a region configured to be seated against a treatment patient for introducing said acoustic waves into said treatment patient, said region having a side facing away from said treatment patient; and
a zone of said bellows wall at said side in said region disposed in a propagation path of said acoustic waves, said zone having a wave altering shape designed to provide therapy to the patient.
15. A bellows as claimed in claim 14 wherein said zone comprises an acoustic mirror.
16. A bellows as claimed in claim 15 wherein said acoustic mirror is a planar mirror.
17. A bellows as claimed in claim 15 wherein said acoustic mirror is a conical mirror.
18. A bellows as claimed in claim 15 wherein said acoustic mirror comprises at least two inclined mirror faces.
19. A bellows as claimed in claim 14 wherein said zone comprises a plurality of regularly arranged objects.
20. A bellows as claimed in claim 14 wherein said zone comprises a plurality of irregularly arranged objects.
21. A bellows as claimed in claim 14 wherein said zone comprises an acoustic filter.
22. A bellows as claimed in claim 21 wherein said acoustic filter is a filter selected from the group consisting of high-pass filters and low-pass filters.
23. A bellows as claimed in claim 14 wherein said zone comprises an acoustic lens.
24. A bellows as claimed in claim 14 wherein said zone comprises an acoustic wave absorber.
25. A bellows for coupling a source of acoustic waves, containing an acoustic propagation medium, to a treatment patient, said bellows comprising:
a bellows wall having a region configured to be seated against a treatment patient for introducing said acoustic waves into said treatment patient, said region having a side facing away from said treatment patient; and
said bellows wall having a wall section in said region composed of a material that is different from a material of a remainder of said bellows wall, said wall section being disposed in a propagation path of said acoustic waves and shaping said acoustic waves in a designed manner to provide therapy to the patient.
