Definitions
- the present invention relates to the field of automated systems for processing samples, in particular but not exclusively biological or chemical samples for the purpose of carrying out an analysis protocol.
- the samples and, where appropriate, the reagents are contained in tubes fitted with a stopper.
- These tubes are introduced into a support, for example the rotor of a centrifuge, or a support of an agitator. They can be introduced directly into housings intended to receive the tubes to be treated, or by means of a basket conferring a degree of angular freedom.
- the tubes are fitted with a stopper which prevents the contents from being projected during agitation or centrifugation operations. Generally, the plug is screwed or pressed onto the end of the tube.
- this plug is fixed to the tube by a hinge allowing the opening or closing of the plug by tilting around this hinge.
- These tubes are for example marketed under the trade name of Cap-Lo®Two-Step Locking Cap by the company Robbins.
- Cap-Lo®Two-Step Locking Cap by the company Robbins.
- the use of tubes fitted with such caps is advantageous for automatic sample processing because, unlike screw caps, they remain attached to the tube. This speeds up the opening and closing process, decreases the risk of product dissemination in the machine and cross contamination between samples.
- the object of the present invention is to remedy this problem by proposing an improved automaton, comprising means making it possible to mechanize the closing and opening of tubes known or adapted specifically for such an automaton.
- the invention relates, in its most general sense, to an automaton for the treatment of samples placed in tubes provided with a tilting plug secured to the body of the tube by a hinge, characterized in that it comprises an uncapping means comprising an arm having a shoulder capable of engaging under a rim of the stopper of a tube, and means for actuating said arm in a direction substantially tangential to the trajectory of said rim during opening by tilting said plug.
- the automatic device according to the invention comprises a centrifugation rotor having housings for positioning said tubes.
- the automaton comprises nacelles for receiving said tubes.
- the uncapping means comprises a plate or an arm pivoting with respect to an axis substantially parallel to the hinge connecting between the stopper and the body of the tube, the end of said arm having a means of engagement with the edge of the stopper. opposite to said hinge.
- the uncapping means comprises a plate extended by at least one tab extending perpendicularly to said plate, the tab being elastically deformable and having a claw capable of coming into engagement with a projecting part of the plug of a tube.
- the uncapping means according to the invention can be adapted to open series of tubes positioned symmetrically. For this, it is provided with two arms or plates pivoting on axes substantially parallel to the connecting hinge between the plug and the body of the tube.
- FIG. 1 represents a partial view of an exemplary embodiment of an uncapping means
- FIG. 2 represents a front view, in decomposed movement, of the uncapping means
- - Figures 3 and 4 show two views of an alternative embodiment
- Figures 5 to 7 show views of another alternative embodiment
- Figures 1 and 2 show a first alternative embodiment of the uncapping means.
- the machine comprises pods (1) in which are housed tubes (2, 3) closed by plugs (4, 5) having protrusions (6, 7) in the shape of an arc at the opposite end of the hinges. a circle a few tenths of a millimeter wide, extending over approximately 40 °.
- An arm (8) movable vertically and horizontally, actuating a tilting plate whose inner face is flat or curved (9) is capable of coming into contact with the surface of the plugs to ensure their closure.
- the arm (8) is driven transversely along a guide rail (11).
- the uncapping means further comprises a plate (20) extended perpendicularly by two tabs
- FIGS. 3 and 4 represent an alternative embodiment.
- the plate has on its lower surface two buffers of elastically deformable foam These pads come to bear on the surface of the stopper during the stopper hooking phase.
- FIG. 5 represents a view of the device at rest. It comprises a jack (30) fixed on the automaton. This jack actuates a movable plate (31) guided laterally. by two rods (32, 33) parallel to the longitudinal axis of the jack (30). These rods (32, 33) have grooves ensuring the locking of the movable plate (31) in the high position and in the low position. To this end, the plate includes pressure balls which are received in the grooves when the plate occupies one of the extreme positions.
- the tilting plate (35) has two articulated claws (35, 36) for hanging the edge of the cap and two pads (38, 39) bearing on the cap when the plate is in the low position, to ensure opening and closing easier.
- the tilting plate (35) is connected to the mobile plate (30) by connecting rods (40, 41).
- the operational mechanism of the tool comprising the tilting plate (35), the articulated hooks (36, 37) and the connecting rods (40, 41) is temporarily made integral with the two axes (32, 33) by means of pressure balls carried by the plate (31) cooperating with circular grooves machined on the axes (32, 33).
- a fixed plate (42) supports a pushing spring cylinder (43) ensuring the opening and closing of the articulated claws (35, 36).
- Figure 6 shows the device in the engagement position on the plugs (50, 51).
- the plate (31) When the jack reaches the end of the pulled position r the plate (31) is in the high position and ensures the rotation of the tilting plate (35) in a position where it rests on the plugs (50, 51).
- the extension of the jack (43) ensures the gripping of the edges of the plugs (50, 51) by the claws (36, 37).
- the tilting plate (35) is in a horizontal position. The tool descends until the tilting plate (35) comes to bear on the upper face of the plugs.
- the jack (30) pushes back down to the low position determined by the grooves formed on the rods (32, 33), the movable plate (31) which drives the entire mechanism that it supports.
- the hooks are in the raised position thanks to a pulling cylinder (53) and engage on the plugs only after an action of the pushing cylinder (43).
- the tilting plate (35) is pushed down, and it then switches to the vertical position. The hooks open the caps. The tool can then be reassembled.
