Abstract
A filtration unit is disclosed for a dialysis machine. The unit includes a casing with a number of first connecting elements and a support provided with a number of second connecting elements. Structure is provided for locking the filter on the support when the first and second connecting elements engage each other. The lock structure may include a pair of slides movable between a locking position, in which locking parts interact with stopping portions, and a release position, in which the filter is not locked to the support. An elastic structure may be provided for resiliently urging the slides into the locking position.

Filtration unit for a dialysis machine, comprising:
- a filter that has a casing provided with a number of first connecting elements arranged on the same side of the casing with respective axes parallel to one another, and
- a support provided with a number of second connecting elements that can interact with the first connecting elements, and with releasable locking means for locking the filter on the support in an operating position in which the first and second connecting elements are in mutual engagement,
- characterized in that the releasable locking means comprise:
- a pair of slides provided with respective locking parts, the slides being movable in a direction transverse to the axes of the first connecting elements between a locking position in which the locking parts interact with respective stopping portions carried by the respective first connecting elements and a release position in which the filter is not locked to the support, and
- elastic means for resiliently urging the slides in the locking position.
Unit according to one of the preceding claims, characterized in that the locking parts extend totally beyond the slides, the stopping portions of the first connecting elements consisting of stopping flanges that can interact with respective free edges of the locking parts.
Support for a filter comprising a casing provided with a number of first connecting elements arranged on the same side of the casing with respective axes parallel to one another, the support being provided with a number of second connecting elements that can interact with the first connecting elements, and with releasable locking means for locking the filter on the support in an operating position in which the first and second connecting elements are in mutual engagement, characterized in that the releasable locking means comprise:
- a pair of slides provided with respective locking parts, the slides being movable in a direction transverse to the axes of the second connecting elements between a locking position in which the locking parts are able to interact with respective stopping portions carried by the respective first connecting elements and a release position, in which the filter is not locked to the support, and
- elastic means for resiliently urging the slides in the locking position.
