Abstract

The invention relates to a treatment device (1) for a device (2) for producing shock waves (4) that are especially suitable for medical use. Said device comprises a housing (3), in which the device (2) for producing shock waves (4) is arranged, a focusing device (5) in which the housing (3) is inserted and which is sealed from the exterior in a liquid-tight manner by a membrane (10), a bellows structure or the like, a liquid (6) with which the focusing device (5) is filled and which encloses the device (2) for producing shock waves (4), and a conduit (7) through which the liquid (6) can be supplied to and discharged from the focusing device (5). The aim of the invention is to allow gases which naturally occur in the water or gas which is produced by the shock wave production to be chemically bound or to be reconverted to water. For this purpose it is e.g. necessary that as few water molecules as possible escape from the water circuit and are therefore present as reactants for the oxygen molecules for producing water. This aim is achieved by connecting the conduit (7) to a container (11) in which the liquid (6) can be chemically degassed in such a manner that the oxygen molecules (17) present in the liquid (6) react with hydrogen molecules (16) to form water (6) or react with a reducing agent.

Claims

1. A treatment device (1) for a device (2) for producing shock waves for medical use, with the device (2) comprising a housing (3) in which the device (2) for generating the shock waves (4) is arranged, and a focusing device (5) in which the housing (3) is disposed and which is sealed to the outside by means of a membrane (10) to provide a liquid-tight seal, with a liquid (6) filled in the focusing device (5) enclosing the device (2) for generating the shock waves (4), and with a conduit (7) through which the liquid (6) can be supplied to the focusing device (5) and can flow out of the focusing device (5), wherein the conduit (7) is connected to a container (11) in which the liquid (6) can be chemically degassed, and wherein oxygen molecules (17) present in the liquid (6) react with at least one of hydrogen molecules (16) to make water, and a reduction agent.

2. The treatment device in accordance with claim 1, wherein a plurality of buffer media (12) is filled in the container (11), by means of which the hydrogen molecules (16) are bound.

3. The treatment device in accordance with claim 2, wherein each of the buffer media (12) consists of synthetic resin pearls (13) with nano or microparticle structures on their surfaces with one or more palladium particles (15) attached thereto by means of at least one nitrogen bonds (14).

4. The treatment device in accordance with claim 3, wherein the palladium particles (15) have a metalized surface onto which the hydrogen molecules (16) can be chemically locked.

5. The treatment device in accordance with claim 1, wherein a chemical substance (18) is added to the container (11) and the hydrogen molecules (16) are transferrable from the substance (18) to the liquid (6) flowing through the container (11).

6. The treatment device in accordance with claim 5, wherein the chemical substance (18) comprises selected one of hydrazine and dilute acids.

7. The treatment device in accordance with claim 2, wherein insides of the container (11) in the area of inlet and outlet openings of the conduits (7) are covered by a selected one of a mat (19), a membrane, and a screen, which cannot be penetrated by the buffer media (12) and the hydrogen molecules (16).

8. The treatment device in accordance with claim 2, wherein at least one of the focusing device (5) and the conduit (7) is provided with a barrier layer made of the buffer media (12), which is impermeable to the hydrogen molecules (16).

9. The treatment device in accordance with claim 1, wherein a pump (8) is arranged in the conduit (7) by means of which the liquid (6) can be pumped through the container (11).

10. The treatment device in accordance with claim 1, wherein both the reduction agent and a reaction product are water soluble.

11. The treatment device in accordance with claim 1, wherein the reduction agent is present in the focusing device (5) and the container (11).

12. The treatment device in accordance with claim 1, wherein the reduction agent is a non-toxic substance.

13. The treatment device in accordance with claim 1, wherein the reduction agent is sodium sulfite.
