The invention more particularly relates to a device for connecting at least one discharge pipe of a product from such an analysis apparatus with means for receiving said product.
    By product is meant both a product or a mixture of gaseous products, solid, such as powdery for example, or in liquid form, viscous and / or in the form of solid elements in liquid suspension. A liquid within the meaning of the present invention may in particular have a solid or semi-solid matrix, such as tissue, respiratory samples, sputum, pus or stool, suspended in a liquid.
    More generally, the invention relates to a connection device that can be implemented in any device, including laboratory analysis, comprising at least one discharge pipe of a product and means for receiving this product. By means of receiving the product is meant, for example, processing means capable of receiving said product and treating it, or means capable of storing said product. Said receiving means may be of any appropriate type depending on the nature of the product discharged and are in no way limiting. The invention also relates to an analysis apparatus equipped with such a connection device, as well as means for receiving the product discharged by such an analysis apparatus and equipped with said connection device.
    Previous state of the art
    It is known from the state of the art an apparatus for extracting nucleic acids from biological samples, in particular by performing "pipetting" operations consisting of sampling, by means of an automated pipette, on the one hand , biological samples and, on the other hand, chemical reagents.
    The biological samples handled are sensitive to contamination so it is imperative that this collection of biological and reagent samples be performed in a completely watertight manner. It is the same for the evacuation of said biological samples and liquid reagents which can be sources of contamination for the following analysis operations and the environment of use of the apparatus.
    Specifically, the apparatus may have a plurality of liquid drain pipes, each pipe discharging liquids from a separate automated pipetting means. For example, two biological sample disposal pipes and / or liquid chemical reagents can be sealingly connected via a connection device to a storage tank.
    According to the state of the art, the connection device has a first part comprising means for sealing connection to the two discharge pipes of the apparatus, and a second part comprising means for sealing with the storage tank of the apparatus. evacuated liquids.
    Said first and second parts are coupled sealingly to each other and comprise complementary means for discharging the liquid through said first and second parts, from the discharge pipe to the storage tank.
    To make it possible to confirm the correct and tight coupling between the first and second parts of the connecting device, two magnets are arranged on one of the parts and are intended to be positioned opposite two magnetic switches arranged on the other part when these are coupled together in a sealed manner. Thus, when the two parts are coupled in a sealed manner, the magnets are at the detection distance of the magnetic switches, which close and transmit a signal indicating the sealing coupling between the first and second parts.
    However, it has been found that, in this configuration of the connection device, it is possible to operate the analysis apparatus while the second part of the connection device is not coupled sealingly with the storage container. liquids.
    As a result, the discharged liquids can flow between the storage bin and the second room. In addition to the disadvantage of the leak, this flow can lead to a risk of contamination of the pipetting zone, and distort the following analysis operations.
    SUMMARY OF THE INVENTION One of the aims of the invention is therefore to overcome the aforementioned drawbacks by proposing a connection device between at least one discharge pipe of a product, such as a liquid, a gas or a gas. solid, derived from an apparatus for carrying out analysis operations, such as pipetting operations for the extraction of nucleic acids, and means for receiving this product, which has a seal and a safety of optimal use, avoiding any risk of leakage of liquid and contamination. For this purpose, it has been developed a device for sealing connection of at least one discharge pipe of a product with means for receiving said product, said device comprising: a first part comprising means for sealing connection to the pipe; - A second part comprising means for sealing with the receiving means.
    Said first and second parts are coupled tightly to one another and comprise complementary means for evacuation of the product through said first and second parts, from the discharge pipe to the receiving means.
    According to the invention, the second part comprises a position sensor arranged to be actuated during the sealing engagement with the receiving means.
    In this way, when the connecting device is sealingly coupled with the product receiving means, the sensor is actuated and transmits a signal to a user to indicate sealing engagement. The risks of leakage and contamination are avoided, the connection device can not be used while coupling with the receiving means is not effected in a sealed manner.
    The means for receiving the product may be of any appropriate type depending on the nature of the product discharged such as, for example, processing means capable of receiving said product and treating it, or means capable of storing said product such as a storage tank for said product.
    According to a particular embodiment, the second part comprises means for moving an activation member of the position sensor, against a sensing member of said position sensor, and in particular towards said body. activation, allowing the passage of the activation member from a neutral position to a detection position, said moving means being actuated during sealing engagement with the receiving means.
    Advantageously, the detection member is arranged on the first piece so that when the second piece is sealingly coupled to the receiving means, the displacement means move the activation member in the detection position, remotely. detecting said detection member.
    In this way, the invention makes it possible, with a single sensor, to detect both, on the one hand, the sealing coupling between the second part and the receiving means and, on the other hand, the coupling between the two component parts of the connection device.
    According to a particular embodiment, the displacement means are in the form of a leaf spring arranged at the coupling means with the receiving means, the activation member is mounted on the leaf of said spring, and the spring is arranged to be compressed during sealing engagement with the receiving means so as to move the activation member into the detection position.
    The leaf spring has, for example, an annular portion with a blade extending, internally and from an edge, preferably diametrically, so as to have a free end located within an area defined by the annular portion. of the spring, said free end receiving the activation member.
    In this configuration, the second part comprises, for example, a movable portion arranged at the coupling means with the receiving means and intended to be relatively displaced in the direction of the spring during sealing engagement with said receiving means. The movable portion comprises an annular shoulder whose peripheral edge facing the spring is chamfered and is capable, during movement of the movable part, to abut against the annular portion of the leaf spring to apply to said spring a concave deformation, counter-resting against an annular support portion formed on the second piece and having the same slope as the chamfered shoulder, so that the spring blade moves the activation member in the detection position.
    The sensor activation and detection members may be of any suitable type without departing from the scope of the invention. For example, the activation member is in the form of at least one magnet. In this particular configuration, the detection member may be in the form of at least one magnetic switch. The invention also aims at protecting an apparatus, preferably of laboratory analysis, such as for example an apparatus for extracting nucleic acids, evacuating a product in a sealed manner in means for receiving said product via at least one drain pipe.
    According to the invention, the apparatus comprises a connection device as described above, the first part of which is sealingly connected to the discharge pipe of the product.
    In the same way, the invention aims to protect the apparatus, preferably laboratory analysis, comprising a connection device and means for receiving the evacuated product. According to the invention, the connection device is in accordance with that described above, the first part of which is sealingly connected to the discharge pipe of the product and the second part of which is sealingly coupled to the receiving means.
    Finally, the invention aims to also protect the sealing means of a product to be evacuated by at least one pipe of an apparatus, preferably laboratory analysis. According to the invention, said receiving means are sealingly coupled to the second part of a connection device according to that described above.
    According to particular embodiments, the means for receiving the evacuated product are, for example, in the form of treatment means, such as a treatment unit able to treat the evacuated and received product, or for example under the form of storage means, such as a storage tank defining a sealed closed volume and comprising for example a threaded neck.

    DETAILED DESCRIPTION OF THE INVENTION The invention relates to a device for connecting at least one discharge pipe of a product with means for receiving said product.
    The connection device can be implemented in any application in which it is necessary to ensure a tight connection between at least one product discharge pipe and receiving means. The invention is described below in connection with an analysis apparatus, such as an apparatus for extracting nucleic acids from biological samples and chemical reagents, discharging a product in liquid form, into receiving means in the form of a storage bin defining a sealed closed volume and comprising a threaded neck. The apparatus, which is well known in the state of the art, makes it possible, in a regular and repetitive manner, to pipette biological samples and chemical reagents in order to extract the DNA and / or the RNA. content (s) in the biological samples. During these pipetting operations, liquid biological and reagent samples are evacuated via two discharge pipes into the storage tank, each pipe discharging liquids from a separate pipetting means. The evacuation of these liquids must imperatively be done in a sealed manner to avoid any contamination of the subsequent extraction and analysis operations performed by the device. For this purpose, the apparatus comprises a connection device sealingly connecting the two pipes to the storage tank for the discharge of liquids as such.
    With reference to FIGS. 1 to 6, the connection device comprises a first part (1) intended to be sealingly connected to the discharge pipes (T), and a second part (2) intended, for its part, to be tightly coupled to the storage bin (not shown). The two parts (1, 2) are coupled tightly to one another, in particular by snapping.
    The first piece (1) and the second piece (2) further comprise complementary means for discharging the liquid through said first and second pieces, from the discharge pipes (T) to the tank of storage.
    Referring to Figure 3, the first part (1) comprises a base (3) of generally cylindrical shape, longitudinally traversed by two male connection ducts (4) to be fitted, on the one hand, on the inside two pipes (T) for discharging liquid from the apparatus and, secondly, into two complementary female connection ducts (5) that the second piece (2) has, intended to be in communication with the interior storage bin.
    These male coupling ducts (4) each comprise an O-ring (6) for sealing and an annular upper groove (7) for latching with locking means (8) of the coupling provided on the female ducts ( 5) and able to engage in said grooves (7) for locking as such. The first piece (1) and the second piece (2) are thus coupled tightly to one another. These male (4) and female (5) pipe connections allow the liquid products coming from the evacuation pipes (T) to pass in a sealed manner and to be discharged through said first and second parts, to the storage tank.
    The base (3) further comprises a guide finger (9) and a polarizing flat (10) both protruding from a bottom wall intended to be opposite the second piece (2).
    With reference to FIGS. 1 and 2, the coupling between the first part (1) and the second part (2) is thus effected by the insertion of the two male coupling ducts (4) in the two female coupling ducts (5). ), and by inserting the guide pin (9) in a complementary cylindrical recess (11) provided on the second piece (2). The polarizing land (10) projecting from the first piece (1) cooperates with a complementary flat portion (12) of the second piece (2). The guiding finger (9) and the flat part (10) allow optimal coupling, without risk of error, and in a guided manner to avoid damaging the O-rings (6) of the male coupling ducts (4).
    Three magnetic switches (13), well known in the state of the art, are positioned on an upper wall of the base (3). These magnetic switches (13) are intended to close when a magnetic member is approached, at a detection distance, on the other side of the base (3), at the level of the bottom wall. The electrical connection of the magnetic switches (13) is conventional and well known in the state of the art so that it will not be described.
    The base (3) of the first piece (1) comprises a protective cover (14) covering the drain pipes (T) and their connection to the male connection ducts (4).
    With reference to FIGS. 4 to 6, the second piece (2) is in the form of a plug for closing the threaded neck of the storage bin. For this purpose, the second piece (2) comprises a closure portion (15) of generally cylindrical shape, intended to be inserted into the neck of the tray and to seal. The closure portion (15) includes an upper annular shoulder (16) having a lower portion provided with an annular seal (17). This annular seal (17) is intended to be in contact, after coupling, with the annular upper edge of the neck of the tray.
    Referring to Figures 4 and 5, a screw ring (18) is arranged around the sealing portion (15) and is intended to be screwed around the neck of the storage tank to ensure a tight coupling, in combination with the annular seal (17) of the sealing portion (15).
    Referring to Figures 5 and 6, a leaf spring (19) is arranged between an upper portion (18a) of the screw ring and the annular shoulder (16) of the sealing portion (15).
    Referring to Figure 7, the leaf spring (19) has an annular portion (20) provided with a blade (21) extending internally and from an edge, preferably diametrically, so as to have a free end located within an area defined by the annular portion (20) of the spring.
    Referring to Figures 8 and 9, the annular portion (20) of the leaf spring (19) is clamped between an upper portion (18a) of the screw ring (18) and the annular shoulder (16) of the shutter portion (15). The peripheral edge of the shoulder (16) facing the spring is chamfered. The upper part of the screw ring (18) has substantially the same slope as the chamfered shoulder (16). In this way, a relative displacement of the sealing portion (15) in the direction of the screw ring (18) compresses the annular portion (20) of the leaf spring (19) to constrain said spring (19) to deform along inclined slopes and take a concave shape to raise the blade (21). This relative displacement between the screwing ring (18) and the sealing portion (15) is achieved when the said screw ring (18) is screwed onto the neck of the storage tank which bears on the annular shoulder (16). ). As a result, when the coupling between the storage tank and the second part (2) is effected in a sealed manner, the blade (21) of the leaf spring (19) is displaced in the direction of the first part (1). .
    That being so, the blade (21) of the leaf spring (19) receives an activation member (22) of a position sensor. This activation member (22) is for example in the form of two magnets (22a) which are thus movable from a neutral position (Figure 8) to a detection position (Figures 2 and 9) when the coupling is made in a sealed manner between the tray and the connecting device, corresponding in particular to the lifting of the blade (21) of the leaf spring (19). The activation member (22) is displaceable against, in particular in the direction of a detection member (23) which consists in particular of two of the three magnetic switches (13) arranged on the first piece (1) of the connection device. The raising of the blade (21) positions the two magnets (22a) opposite and at a distance of detection of the two magnetic switches (13) which close to indicate to a user the tight coupling between the storage tank and the connection device. The invention thus provides a connection device comprising a position sensor having an activating member (22) arranged on the second piece (2) and movable in a detecting position only when the device is sealingly coupled to the tray. storage, in the direction and in the detection field of the detection member (23) which is arranged on the first piece (1). In this way, the detection can be done only if the first piece (1) and the second piece (2) are coupled tightly between them. In other words, with a single sensor the invention makes it possible to detect both, on the one hand, the sealed coupling between the second part (2) and the storage bin and, on the other hand, the coupling between the two parts (1, 2) constituting the connection device.
    The connection device thus guarantees optimum safety of use since the device is able to warn the user when it is coupled in a perfectly sealed manner, which makes it possible to avoid the risks of leaks and contamination. Advantageously, the magnetic switches (13) of the detection member (23) are subject to the apparatus so that the apparatus can not function until said magnetic switches (13) are closed, which means that the couplings are not waterproof.
    To further ensure safety of use, the connection device includes an overflow sensor able to signal to the user that the volume of liquid in the storage tank is greater than a given threshold. For this purpose and with reference to Figure 5, the closing portion (15) comprises a cylindrical duct (24) longitudinal and non-through. The duct (24) is open on the side of the storage bin and communicates therewith. This duct (24) slidably receives a float (25) equipped with a magnet (26) in the upper part. This magnet (26) is intended to be positioned in line with the third magnetic switch (13) of the first piece (1) when the first piece (1) is coupled with the second piece (2). In practice, the float (25) slides in the cylindrical duct (24) as a function of the level of the liquid inside the tank, and is pushed towards the magnetic switch (13) so that, when the volume of the liquid in the tank exceeds a certain threshold, the magnet is at a sensing distance from the magnetic switch (13) which closes to indicate the overflow.
