Animal restraint device

Abstract

A device (4) for restraining an animal in a magnetic resonance imaging system is proposed. The device (4) comprises: - a base plate (6) having a first face (6a) and a second face (6b) opposite the first face (6a), - two side walls (7, 8) extending from the second face (6b) on the same side of said second face, - two guide rails (9) disposed on the second face (6b) and extending transversely, and - two mounting bases (10) slidably mounted inside each guide rail, each side wall (7, 8) being removably mounted on one of the mounting bases of each rail, - each mounting base (10) supporting a manually actuated locking device adapted to cooperate with the associated rail to lock said base in position along said rail (9).

Claims

extending projecting from the pin and inserted into a groove (25) of complementary shape which extends the associated housing (24).

7. Device according to claim 1, in which each locking device (31) comprises a cam (36) movable between an inactive position allowing the sliding of the associated mounting base (10) in the associated guide rail, and an active locking position locking said mounting base (10) in position, the cam (36) being in contact with the associated rail in the active locking position.

8. Device according to claim 7, in which each locking device (31) further comprises a lever (37) manually actuable for the passage of the cam (36) from the inactive position to the active position, and vice versa.

9. Device according to one of claims 7 and 8, in which each side wall (7, 8) comprises, at each of its ends, an assembly pin (40) and each mounting base (30) comprises a housing (35) inside which one of the assembly pins (40) extends in part.

10. Device according to any one of the preceding claims, further comprising means (28) for supporting the animal and means for fixing the support means (28) to the side walls (7, 8) so that the support means (28) extends between the two side walls (7, 8) and at a distance from the second face (6b) of the base plate.

11. A magnetic resonance imaging system (1) comprising an examination tunnel (2), a table (3) intended to be inserted into the examination tunnel (2), and a holding device (4) according to any one of the preceding claims, the first face (6a) of the bottom plate (6) resting on the table (3). 3 / 4
