Abstract

The invention relates to blood processing apparatus comprising a cabinet (2) defining at least an interior housing (6) and presenting an aperture (6a) for allowing access from outside into said housing. The apparatus has a user interface (13) mounted in a movable manner on the cabinet between at least a first position, where the user interface is adjacent to the cabinet in correspondence of said aperture, and a second position, where the user interface is spaced apart from the aperture and opens the access to said housing.

Claims

1. A blood processing apparatus comprising a cabinet (2), a user interface (13), and cinematic coupling means (14), the cabinet (2) defining at least an interior housing (6), the cabinet presenting an aperture (6a) for allowing access from outside into said housing, the user interface (13) being mounted on the cabinet, said user interface being movable from a first position, where the user interface closes said aperture and prevents access through said aperture into said housing, and a second position, where said aperture is not closed by said user interface so that access through said aperture into said housing is permitted, said user interface comprising a display screen, said cinematic coupling means (14) being interposed between the cabinet and the user interface (13) and being operative to move the user interface along a prefixed arc-shaped trajectory from said first position to said second position, said display screen being viewable by a user looking horizontally (a) when the user interface is in the first position, (b) when the user interface is in the second position, and (c) during the entire movement of the user interface from the first position to the second position.

2. Apparatus according to claim 1, wherein the cinematic coupling means (14) comprises at least a first element (15) having a first end pivotally engaged to the user interface and a second end pivotally engaged to the cabinet.

3. Apparatus according to claim 2, wherein the cinematic coupling means (14) comprises at least a second element (16) having a first end pivotally engaged to the user interface in position displaced from the first end of the first element, and a second end pivotally engaged to the cabinet in a position spaced from the second end of the first element, said first and second element elements forming a first articulated parallelogram.

4. Apparatus according to claim 3, wherein the cinematic coupling means (14) comprises at least a third element (19) having a first end pivotally engaged to the user interface and a second end pivotally engaged to the cabinet.

5. Apparatus according to claim 4, wherein the cinematic coupling means (14) comprises at least a fourth element (20) having a first end pivotally engaged to the user interface in position displaced from the first end of the third element, and a second end pivotally engaged to the cabinet in a position spaced from the second end of the third element, said third and fourth elements forming a second articulated parallelogram.

6. Apparatus according to claim 5, wherein the first and second articulated parallelograms operate in correspondence of respective opposite sides of the cabinet.

7. Apparatus according to claim 5, wherein the first and second articulated parallelograms are identical and symmetrically engaged to the cabinet.

8. Apparatus according to claim 1, wherein the cinematic coupling means (14) comprises a rotating base (22) which is pivotally engaged to the cabinet (2) around an axis of rotation (21) and which bears the user interface (13), the rotating base allowing rotation of the user interface around said axis to bring the user interface to a third position distinct from said first and second positions.

9. Apparatus according to claim 8, wherein the cinematic coupling means (14) includes at least a first element (15) having a first end pivotally engaged to the user interface and a second end pivotally engaged to the rotating base.

10. Apparatus according to claim 9, wherein the cinematic coupling means comprises (14) at least a second element (16) having a first end pivotally engaged to the user interface in position spaced from the first end of the first element, and a second end pivotally engaged to the rotating base in a position spaced from the second end of the first element, said first and second elements forming a first articulated parallelogram.

11. Apparatus according to claim 10, wherein the cinematic coupling means comprises at least a third element having a first end pivotally engaged to the user interface and a second end pivotally engaged to the rotating base.

12. Apparatus according to claim 11, wherein the cinematic coupling means comprises at least a fourth element having a first end pivotally engaged to the user interface in position spaced from the first end of the third element, and a second end pivotally engaged to the cabinet in a position spaced from the second end of the third element, said first third and fourth elements forming a second articulated parallelogram.

13. Apparatus according to claim 12, wherein the first and second articulated parallelograms operate in correspondence of respective opposite sides of the cabinet.

14. Apparatus according to claim 8, wherein the base comprises a tubular portion (30) coaxial to said axis (21) and engaging a corresponding tubular and coaxial mating portion (28) carried by the cabinet, said tubular portions allowing pivoting of the rotating base and defining a passage.

15. Apparatus according to claim 1, wherein the cabinet presents a box-like structure having a base portion (3), a main body (4) vertically extending from said base and a top portion (5) extending above said main body and wherein the user interface is positioned in correspondence of said top portion.

16. Apparatus according to claim 8, wherein the user interface (13) in said second position is entirely above said cabinet and able to rotate around said axis (21) to reach the third position angularly spaced with respect to the second position.

17. Apparatus according to claim 16, wherein the user interface (13) can be moved from said third position to a fourth position where the user interface is approached again to the cabinet in a position different from said first position.

18. Apparatus according to claim 17, wherein the third position is 180°

angularly spaced with respect to the second position and wherein the coupling means (14) allow to displace the user interface (13) from said third to said fourth position by lowering the user interface according to a predetermined path.

19. Apparatus according to claim 1, wherein the user interface (13) comprises a support body (101) engaging the coupling means, and wherein the display screen (100) is mounted on the support body.

20. Apparatus according to claim 19, wherein the support body (101) presents an L-shaped profile and comprises a first portion (103) receiving the display screen and a second portion (104), transversal to the first portion, defining a receptacle area (105) on the top of the cabinet.

21. Apparatus according to claim 19, wherein the user interface presents side portions (106), interacting with the cabinet side walls and preventing rotation at least during part of the movement between the first and the second position.
