Definitions

• the present invention relates to the field of biological analysis and preservation of biological samples.
• micro titration plates It is known in the prior art to use plates, called micro titration plates. These plates generally have a multitude of wells organized in a two-dimensional network. Each of these wells can contain a biological sample.
• micro titration unit comprising at least one container which is made of a transparent material and which has an orifice intended to receive a reaction mixture for biological test.
• European patent EP688602 describes a microtest plate comprising a frame and a central part provided with separable containers. These containers are independent parts inserted in the frame. These plates are widely used in biological analysis laboratories. The contents of the wells are transferred to a well reader in which a biochemical reaction occurs using pipettes. These pipettes are sometimes automated and supported by a robot, allowing multipipettage. However, these are solutions requiring either great dexterity or expensive equipment.
• the object of the invention is to provide a plate allowing separation of the wells as and when required, thus avoiding the transfer of the content of the plates to the analysis equipment, easily industrializable without requiring an assembly step. of different components.
• a plate also allows the conservation of any type of biological samples in the form of a single plate, and the use of a well in when needed.
• the invention relates more particularly to a plate intended in particular for micro titration, having a plurality of detachable cups for receiving samples of a biological liquid characterized in that it is constituted by a single piece of molded plastic material having an upper surface extended by lateral faces, the upper face having a plurality of buckets connected to the upper surface of the plate by a weakening zone, the buckets having an upper crown capable of cooperating with a complementary tool intended to exert a torque torsion causing the weakening zone to rupture.
• the plate according to the invention consists of a piece of molded plastic material having a plurality of hollow protuberances constituting the cups, each of these protuberances being surrounded by a breakable line.
• the buckets are surrounded by an area alternately having radial reinforcements extending the bucket, and openings with a section at least equal to that of the radial reinforcements.
• the buckets are surrounded by a rupture zone having semi-circular shoulders forming an inclined plane on which the radial extensions of the buckets slide when they are separated from the plate by a rotational movement.
• the cups have an individual identification marking.
• the plate has an individual identification mark.
• the identification marks consist of bar codes embedded in the plastic.
• the identification marks are constituted by means capable of being read from a distance, embedded in the plastic.
• the plate 1 according to the invention further comprises plugs adaptable on at least part of the cups to close said cups tightly.
• the plate is coated before use with a tamper-evident film.
• the plate according to the invention has a slot for the introduction of a blade carrying a remote identification label.
• the blade has at least one locking notch.
• FIG. 1 shows a front three-quarter view of a plate according to the invention
• FIG. 2 represents a rear three-quarter view of a plate according to the invention
• FIG. 3 shows an enlarged view, from above, of the plate.
• FIG. 4 represents an enlarged view, from below, of the plate;
• FIG. 5 represents an exploded view of a variant plate according to the invention.
• Figure 1 shows a three quarter front view of a plate according to the invention.
• the plate is produced by plastic molding. It has an upper surface (1) extended by a peripheral border (2) and forms a hollow box, the lower surface of which is open and the upper surface has a network of cylindrical indentations inside which are placed buckets (3) connected to the edge of the cylindrical indentation by a breakable zone formed by a weakening line of lesser thickness than the rest of the plate.
• the peripheral edge (2) is convergent to allow stacking or partial nesting of the superimposed plates.
• the cups have an upper part surrounded by a notched crown (4), surmounting the breakable zone of connection with the edge of the recess, and a lower part located below the upper surface of the plate.
• the buckets are therefore molded simultaneously with the frame and the upper surface. The separation surface between the two parts of the mold pass through the upper plate and through the weakening zones.
• the upper part of the plate therefore comprises the upper surface and the notched crowns, and the lower part the lateral faces and the substantially cylindrical lower part of the cups forming the receptacles for the samples to be analyzed.
• This notched crown (4) can receive a key (5) of complementary section.
• This key (5) makes it possible to exert on the crown (4) of a cup a torsional torque producing a rupture of the breakable zone (6) surrounding the cup.
• Figure 2 shows a rear quarter view of a plate according to the invention.
• the cup (3) has the shape of a hollow cylindrical body (7).
• the height of the buckets is slightly lower than that of the peripheral edge (2), so as to allow the plate to rest in stable equilibrium on a flat surface.
• FIG. 3 represents an enlarged view, from above, of the plate.
• the upper plate has lights (25) whose edge constitutes the weakening zone. These lights (25) surround the buckets (3).
• These slots have tabs (26 to 28) extending towards the center of the slots, and coming into contact with the peripheral surface (29) of the bucket.
• the semi-annular intervals between these legs (26 to 28) correspond to a system of complementary ramps, one of the parts of which is secured to the bucket and the other part of which is secured to the plate, the two parts being separated by rupture zones.
• the crown (4) is notched in shape and has an alternation of grooves (9) and projecting bosses (10).
• the crown (4) also has radial extensions (11, 12) constituting reinforcement zones.
• the connection between the crown (4) and the surface of the plate (1) is made by a weakening zone (13) surrounding the crown.
• the weakening is achieved by a reduced thickness of plastic material facilitating breaking when a force is exerted on the crown, in particular using the key (5) making it possible to transmit a torque.
• Figure 4 shows an enlarged view from below.
• the cylindrical body (7) is surrounded by the weakened zone.
• the plate has zones (14) in the form of a helical ramp on which the radial extensions (11) slide.
• the plate can be produced by molding in a mold with a single drawer.
• the plates can each carry a specific means of identification, for example a bar code, a two-dimensional code molded in the plastic.
• each of the buckets can carry a specific identification means, for example a bar code, a two-dimensional code molded in the bottom of the cylindrical part.
• a variant consists in equipping each plate with a coded radio frequency or magnetic label.
• This label which can take different forms, for example the form of an integrated circuit or a coded magnetic wire, can be integrated into the material, to allow remote identification.
• This identification can be carried either on the plate or on the bucket.
• the plate can be marked with a unique code, and the buckets marked with a code comprising the identification code of the plate supplemented with a code specific to the bucket.
• FIG. 5 shows an exploded view of an alternative embodiment of the plate according to the invention.
• the cups are closable by plugs (20).
• the plugs (20) have a thread and a seal for seal the cups (3).
• the plate has, on the upper face, a slot (21) opening onto a substantially parallelepipedal cavity into which can be inserted a blade (22) having lateral notches (23, 24) intended for locking the blade (21) in the cavity of the plate in order to prevent the withdrawal of the blade after a first introduction.
• the blade (22) supports a radio-frequency label making it possible to identify and identify the plate securely.
