Cuvette for in vitro diagnosis
View Patent ↗The device comprises reaction unit cuvettes for different types of tests, a vertical axis rotor which is associated with a rotation drive means and provided with a horizontal gear-teeth crown delimiting radially outwardly open cavities for receiving the reaction unit cuvettes, a device for supplying the gear-teeth crown with the reaction unit cuvettes, a device for supplying cuvettes with analyzable biological liquid samples, stations arranged around the crown for carrying out measurements and/or analysis and an automation for managing the sequences of a desired process for each cuvette.
1. A unit cuvette for an analytical device for in vitro diagnosis comprising:
a base,
a lower part,
an upper part,
means of attachment in a first direction to at least one other unit cuvette, and
means of attachment in a second direction, substantially perpendicular to the first direction, to at least one other unit cuvette,
wherein:
the means of attachment in the first direction comprise at least one hook positioned on an edge of the upper part of the unit cuvette, and
the means of attachment in the second direction comprise two rims, a first rim forming an upwardly open hook and a second rim forming a downwardly open hook, the upwardly open hook being able to slot into the downwardly open hook of a neighboring unit cuvette, the upwardly open and downwardly open hooks being positioned on the base of the unit cuvette, along two edges of the unit cuvette orthogonal to the edge of the upper part of the unit cuvette equipped with the hook.
2. The unit cuvette as claimed in claim 1 , wherein the unit cuvette is made of a transparent plastic compatible with the various reactions that the unit cuvette may receive.
3. The unit cuvette as claimed in claim 1 , wherein the lower part of the unit cuvette has a parallelepipedal shape.
4. The unit cuvette as claimed in claim 3 , wherein the parallelepipel lower part of the unit cuvette extends upwards by means of the upper part of the unit cuvette, the upper part of the unit cuvette being tapered and opening out upwards.
5. The unit cuvette as claimed in claim 1 , comprising a cuvette bottom with a low point.
6. The unit cuvette as claimed in claim 1 , wherein the means of attachment in the first direction comprise at least one downwardly open hook positioned on one of the edges the upper part of the unit cuvette.
