A peristaltic hose pump comprising a roller wheel, which can rotate about a roller wheel axis and which has rollers that are mounted on the roller wheel. The rollers roll along a circular path having a certain radius with respect to the roller wheel axis. The peristaltic hose pump also comprises a pressure arched element with a supporting surface, whereby the supporting surface extends along a circular path having a certain radius around the rotation axis of the roller wheel. In addition, a flexible hose can be inserted between the supporting surface and the rollers of the roller wheel.

The invention claimed is: 1. A peristaltic hose pump comprising: a roller wheel which can rotate about a roller wheel axis D and which has rollers that are mounted on said roller wheel, wherein said rollers roll along a circular path having a radius R1 with respect to said roller wheel axis D; a pr
The invention claimed is: 1. A peristaltic hose pump comprising: a roller wheel which can rotate about a roller wheel axis D and which has rollers that are mounted on said roller wheel, wherein said rollers roll along a circular path having a radius R1 with respect to said roller wheel axis D; a pressure arched element with a supporting surface, wherein said supporting surface extends along a circular path defining an extension having a radius R2 around said rotation axis D of said roller wheel; a flexible hose inserted between said supporting surface and said rollers of said roller wheel, said supporting surface being made of an elastically deformable synthetic material, said pressure arched element being pre-shaped such that said extension of said supporting surface, when said pressure arched element is not under tension, essentially corresponds to said extension of said supporting surface when under tension, wherein a fixation device comprises a dowel pin located at an end of said pressure arched element and a closing plate, said closing plate being rotatably mounted around a tension rotation axis running parallel to said rotation axis D of said roller wheel, whereby said closing plate interacts with said dowel pin such that said dowel pin leaves a first snatch post and is pressed into a second snatch post of a clamping disk when said closing plate is turned from a hose mounting position to an operating position. 2. A peristaltic hose pump according to claim 1, wherein said synthetic material is polyoxymethylene (POM). 3. A peristaltic hose pump according to claim 1, wherein said synthetic material has a modulus of elasticity in tension of ≧1000 MPa (megapascal), a bending fatigue strength of ≧10 MPa, and an impact strength at a room temperature of 23째 C. of ≧70 KJ/m2 (kilojoules per square meter). 4. A peristaltic hose pump according to claim 3, wherein said synthetic material has a modulus of elasticity in tension of ≧3000 MPa (megapascal), a bending fatigue strength of ≧30 MPa, and an impact strength at a room temperature of 23째 C. of ≧130 KJ/m2 (kilojoules per square meter). 5. A peristaltic hose pump according to claim 1, wherein said pressure arched element has a run-in zone, a middle zone and a run-out zone, whereby at least said run-out zone has a larger cross section as compared with said middle zone. 6. A peristaltic hose pump according to claim 5, wherein said run-in zone also has a larger cross section as compared with said middle zone, an increased thickness in directions orthogonal to said supporting surface. 7. A peristaltic hose pump according to claim 1, wherein a middle zone extends across an angle of 10째 to 90째 an embracing of said roller wheel by said hose and with respect to said roller wheel axis D, said pressure-arched element extends across an angle of 90째 to 180째. 8. A peristaltic hose pump according to claim 1, wherein, with respect to said rotation axis D, said pressure arched element extends across an angle of 90째 to 180째. 9. A peristaltic hose pump according to claim 1, wherein said pressure arched element is at its first end mounted on a pivot axis rigidly arranged on a hose pump and running parallel to said rotation axis D of said roller wheel, and at its second end by a pivoting means of a fixation device so that it can pivot between a hose mounting point and an operating point. 10. A peristaltic hose pump according to claim 1, wherein, in an operating position, a closing plate facially covers said roller wheel as well as said hose placed around it, in such a way that said hose is fixed in the direction of said rotation axis D of said roller wheel. 11. A peristaltic hose pump according to claim 1, wherein, in an operating position, a closing plate is positively engaged in place. 12. A peristaltic hose pump according to claim 1, wherein said roller wheel and said pressure arched element are replaceable. 13. A peristaltic hose pump according to claim 1, wherein, with respect to their radial difference R2-R1, said roller wheel and said pressure arched element can be selected with the stipulation that in mounting position a prescribed hose with an outer diameter of less than R2-R1 can be inserted. 14. A peristaltic hose pump according to claim 1, wherein, with respect to their radial difference R2-R1, said roller wheel and said pressure arched element can be selected with the stipulation that a prescribed hose with a wall thickness of <(R2-R1)/2 can be inserted. 15. A peristaltic hose pump comprising: a roller wheel rotating about a roller wheel axis D and having rollers mounted on said roller wheel, wherein said rollers roll along a circular path having a radius R1 with respect to said roller wheel axis D; a pressure arched element with a supporting surface, whereby said supporting surface extends along a circular path having a radius R2 with respect to said roller wheel axis D; and a closing plate rotatably mounted around a tension rotation axis S running parallel to said roller wheel axis D and having a mounting position and an operating position, wherein a flexible hose is inserted between said supporting surface and said rollers, wherein said supporting surface is made of an elastically deformable synthetic material, and said pressure arched element is pre-shaped with the provision that an extension of said supporting surface, when said pressure arched element is not under tension, essentially corresponds to said extension of said supporting surface when under tension. 16. A peristaltic hose pump comprising: a selective pressure inducing guide for a flexible hose defined by an inner guide means including a roller wheel with a circular perimeter rotating about an axis D having a plurality of rollers, each of said rollers mounted near the outer edge of said circular perimeter to rotate about its own axis, said plurality of rollers combining to form an inner circular path with an annular radius R1 with respect to said axis D for said flexible hose; an outer guide means including a pre-shaped pressure arched element with a flexible supporting surface extending to form an outer circular path with an annular radius R2 with respect to said axis D for said flexible hose; and a closing plate rotatably mounted around a tension rotation axis S running parallel to said roller wheel axis D and having a mounting position and an operating position, wherein said closing plate includes an actuating means which can be actuated to close said closing plate by hand and said supporting surface, made of an elastically deformable synthetic material, retains its shape when tension is applied by said flexible hose inserted between said inner guide means and said outer guide means with said closing plate in said operating position.
