- Such devices also called automated analysis, allow to automate certain protocols, such as for example the distribution of liquids in gel cards.
- This protocol consists in pouring a predetermined quantity of liquid using a liquid dispensing device into a reaction well of a gel card generally containing one or more reagents.
- This liquid may for example be a blood sample, or any other type of human sample.
- a gel card is a receptacle comprising a body in which are formed one or more reaction wells in which biological reactions take place.
- the wells of the gel card are initially sealed by a seal which is sealed to the body. Most often, this seal consists of a thin aluminum strip.
- the operation of dispensing liquids into reaction wells is carried out by piercing the lid with the aid of a liquid distribution device provided with a needle in order to open one or more wells. Then, the liquid is poured into the well or wells using the same needle.
- a disadvantage is that the repetition of the piercing operation of the metal cap damages the tip of the needles. The latter must therefore be regularly dismantled and changed, which has a significant cost and also requires stopping the PLC.
- An object of the present invention is to overcome these disadvantages by providing a receptacle and a solution for opening the wells of said receptacle without piercing its lid.
- the present invention relates first of all to a gel card-type receptacle comprising a body in which several adjacent wells are initially sealed by a lid having a length and a width, in which the lid has at least one precut between two adjacent wells. so as to form at least a sealing cap portion at least one of the wells of the receptacle.
- This pre-cut can be made in the lid before it is sealed to the body of the receptacle, or afterwards, with the aid of a suitable cutting machine, for example equipped with one or more coaxial circular saws and arranged perpendicularly. compared to the plane of the operculum. Furthermore, it is understood that thanks to the receptacle according to the invention, it is easy to open one of the wells of the receptacle by removing the portion of the cap which covers said well.

- Each pad 130 has a rest position, as well as a working position in which said pad is brought in abutment against a portion of the cap, that is to say here in abutment against the upper wall 412a of the body 412 of the gel card 410.
- the pads are preheated before being brought into the working position.
- the heating pads 130i, 130 3 and 130 4 are moved vertically along the arrow F3 to be respectively brought against the lid portions 418a, 418c and 418d.
- the removal of the lid portions is done by bringing the heating pads 130 130 3 and 130 4 to their rest position, in other words by moving vertically in the direction symbolized by the arrow F4 (opposite the arrow) F3) of Figure 8. It was found that the lid portions are carried by the pads during the ascent thereof. However, it is preferable, but not essential, to provide the heating pads with means 134 to grip the lid portions, these means which may be for example in the form of small claws or points 134.
- the station according to the invention comprises several evacuation members to expel the lid portions gripped by the heating pad.
- the station comprises six evacuation members consisting of six rods 132i to 132e. These rods are fixed to the frame 102 and are arranged in such a way that the gripping devices (the pads) slide around said rods. Each heating pad and each rod thus form a unitary assembly, the rod being included inside the heating pad.
- the rods are fully housed in the heating pads when they are in their working position, and protrude when the heating pads are returned to the rest position.
- the rods 132i, 132 3 and 132 4 expel the lid portions 418a, 418c and 418d which, in this example, then fall into a tray of recovery 133.
- the tray 108 is moved so as to cause the gel card 410 close to means 140 to check whether the selected wells 414 t, 414 3 and 414 4 have been correctly opened.
- these means consist of a set of optical sensors which are arranged to be arranged above the upper wall. These sensors are able to detect the absence of metal seal portions and thus the opening of the selected wells.
- non-optical verification means could be provided.
- the station comprises at least one ionizer 150 for ionizing the selected wells, after their opening, in order to eliminate the electrostatic charges that may be contained in the wells.
- the selection mechanism 200 which makes it possible to select the gripping devices (pads) 130 to be moved to their working position, as well as the displacement device 300 for moving the gripping devices (pads) 130 between their rest position and their working position.
- FIG. 11 shows one of the heating pads 130 in the rest position, according to a view taken in a vertical section plane and parallel to the direction of movement of the plate 108.
- the heating pad 130 In the rest position, the heating pad 130 is in contact with a heating floor 160 which is fixed to the frame 102.
- This heating floor comprises for example electrical resistances to maintain a substantially constant temperature.
- the heating pad 130 therefore does not include internal heating means. In other words, the heating pad 130 captures the thermal energy when in the rest position.
- the heating sole 160 is configured in such a way that the heating pad can be rapidly brought to a temperature of the order of 200 ° C.
- the heating pad will preferably be made of a material of the bronze type, or any other material which is good conductor while having a good coefficient of friction.
- the heating stud 130 (130i, 130 2 ) is slidably mounted around the rod 132 (132i, 132 2 ), the latter being fixed to the frame 102 and, in this example, to the heating sole 160.
- the stud 130 is moved vertically by the displacement device 300 which comprises a vertically movable plate 302 whose lower end carries a compression spring 304.
- the latter exerts a pressure against a horizontal bearing surface 13 (131 ⁇ , 131 ' 2 ) belonging to a radial extension 131 (131i, 131 2 ) of the heating stud 130.
- the spring 304 exerts a pressure on the bearing surface 131 ', which has the effect of vertically displacing the plot towards the gel card 410, in the direction indicated by the arrow F6, to bring it into its working position in which it is in contact with the lid portion 418.
- the selection mechanism comprises several fingers 202 (202i, 202 2 ) which are movable transversely relative to the direction of movement of the pads 130, between a retracted position and an extended position. More specifically, in this example, there are provided as many moving fingers as heating pads.
- FIGS. 11 to 13 show that the displacement of the fingers 202 (202 1a 202 2 ), in this case a horizontal translation, is performed thanks to an electromagnet 204 (204i, 204 2 ) connected to the finger via a rod 206 (206 !, 206 2 ).
- the pad 130 comprises meanwhile a horizontal abutment surface 133 (133i, 133 2 ) intended to cooperate with the finger 202 (202i, 202 2 ) when the latter is in its extended position, as can be seen in FIG. 13.
- the pad 130i which is then a selected pad, can be brought into the working position by the vertical displacement of the plate 302, the finger 202i not opposing the displacement of said pad.
- the displacement of the plate 302 causes the simultaneous movement of all the pads during the uncapping operation. However, only the studs for which the associated finger is in retracted position (the selected pads) are brought into working position. In other words, it is understood that the selection mechanism makes it possible to prevent the displacement of the pads that are not selected.
- the invention allows selective opening of the wells of the gel card, and this automatically.
