Definitions
- the present invention relates to a communication device, with a coupling means, of a first enclosure, and of a second enclosure, each being sealed with respect to an external medium, for example atmospheric air, and in front of remain watertight with respect to said medium, notwithstanding their communication. Consequently, the communication device, while operating in a reversible manner, is arranged to also preserve the seal, with respect to the same external environment, of the passage established between the two enclosures.
- an external medium for example atmospheric air
- Constant or “contamination” means the characteristic that a substance must remain excluded, or in a limited quantity or concentration, in a given medium. These are, for example, pathogenic agents, or pollutants, biological or other, but also simple solid, liquid, or gaseous particles, which can be suspended in any fluid medium.
- one of the enclosures being fixed is constituted in particular by a clean room or sterile, and the other enclosure is removable, for example for single use, and contains one or more objects, or a load to be transferred in the coupled position of the communication device, through the passage thus established between the two enclosures, knowledge of the removable enclosure to the fixed enclosure, for example to supply the latter with components or products required by a manufacturing or production in progress in the clean room, or conversely to evacuate waste or products from said room .
- such a device comprises:
- a first closure member comprising a first flange providing a seat for a first removable door element with a seal between the seat and the door;
- a second closure member comprising a second flange providing a seat for a second removable door element, with a seal between the seat and the door; - means of tight connection between the two flanges, determining an external critical line, peripheral and continuous, liable to be contaminated, and means of sealed joining of the two door elements, determining an internal critical line, peripheral and continuous, susceptible to be contaminated, contiguous to the exterior critical line;
- critical line a line with residual contamination by the environment external to the two enclosures connected. During or after coupling, this line is likely to come into contact with the atmosphere or fluid present in the passage established between the two enclosures, or in contact with the product or products crossing said passage, and to contaminate them.
- the present invention proposes to limit the possible contamination by the critical line (s), without resorting to decontamination of the latter before coupling, and without complicating the coupling means adopted, both in its structure than in its functioning.
- the flexible bag in the uncoupled position of the coupling means, comprises, opposite its bottom, a strip extending it continuously beyond the flange of the corresponding closure member, determining a flexible envelope closed and sealed, but openable, in which is disposed the main part of the corresponding closure member, and comprising an annular band linked to said corresponding flange, for sealingly separating the interior of the bag from the inside the protective cover.
- continuous is meant the characteristic that the wall of the flexible bag is continuous with respect to the required seal with respect to the external environment, between the body of the bag on one side, forming its main part, and on the other side the strip forming the protective envelope.
- This continuity is obtained in different ways, namely either by a continuity of material, or by a weld or seal between the body of the bag and the strip. Thanks to the invention, the component of the critical line or lines located on the side of the closure member of the flexible bag, is completely protected by the protective envelope, before coupling with the other member d shutter.
- the solution according to the present invention also makes it possible to ensure better long-term tightness of the corresponding enclosure inside the flexible bag, since the tightness of said bag relative to the flange of the corresponding closure member n 'is more involved in the sealing of said bag vis-à-vis the external environment; this of course considering that the interior of the protective envelope and the interior of the bag are under pressure, for example under vacuum.
- the flexible bag with its additional strip, as defined above is functionally only one and the same closed sheath, for example welded at its two ends, namely on either side of the corresponding obturation member.
- the flexible bag is the flexible bag, and it alone, having, as previously indicated, the form of a closed sheath, which ensures the seal, and of the corresponding closure member, and of the load, during the entire storage period of the disposable set defined above.
- the solution according to the invention also makes it possible to further limit the possible contamination resulting from the handling of the single-use assembly associating or bringing together the obturation member, adapted to be coupled to the other obturation member ( on the side of the fixed enclosure for example), and the flexible and waterproof bag. Indeed :
- the removal of the protective envelope can be done with the hands, without the latter coming into contact with the front face of the door of the corresponding shutter member; - And the protective envelope assures the user that the shutter member and in particular its door have remained uncontaminated before opening the envelope.
- FIG. 1 shows, seen in section and schematically, a disposable assembly according to the invention, having just been extracted from an overpack initially vacuum;
- FIG. 2 shows, always seen in section and schematically, a communication device according to the invention, which includes the assembly shown in Figure 1; this device is shown in its coupled position, before the opening towards the inside of the door formed by the integral joining of the two door elements of the device according to the present invention.
- a device 10 according to the invention makes it possible to put into communication:
- a first enclosure consisting for example of a clean room, inside which a manufacturing plant is located, which requires a supply of bulk components, identified for example under the reference 14 in FIG. 1, in particular rubber stoppers; this first enclosure is embodied by a sealed partition 55 vis-à-vis an external environment 3, consisting of an atmosphere, for example normal and atmospheric, it being understood that the first enclosure is itself in a sterile or decontaminated atmosphere, in slight overpressure or depression compared to the external environment 3;
- a second enclosure 2 defined by the interior of a flexible and waterproof bag 15, for example under vacuum; the bag 15 belongs to a removable, single-use assembly, operatively associating a closure member 42 with said bag; the bag 15 comprises at least one object 14, or a load to be transferred to the enclosure 1; this load is itself sterile or decontaminated.
- a device 10 makes it possible to put the enclosures 1 and 2 in communication, while preserving their tightness vis-à-vis the external environment 3.
- This device comprises: - on the side of the first fixed enclosure 1, a first closure member 41, itself comprising a first flange 51, providing a seat 51a for a first removable door element 71, with a seal 81 of sealing between the seat 51a and the removable element 71; - on the side of the second enclosure 2, removable and for single use, a second closure member 42, comprising a second flange 52, providing a seat 52a for a second removable door element 72, with a seal 82 of sealing between the seat 52a and the removable element 72.
- the shutter members 41 and 42 are designed to be coupled to each other in a leaktight but reversible manner, as follows:
- the first shutter member 41 forms a female part, by a bore 51b formed in the flange 51, and the second shutter member 42 forms a male part, by the fitting of the flange 52 in the bore 51b; locking means 57, represented by dotted lines, taking into account the diversity of their possible embodiments, make it possible to lock the 7
- the first seal 81 also serves to ensure continuous peripheral sealing between the two door elements 71 and 72, by sealingly sealing up the contamination of their respective front faces;
- the support between the flanges 51 and 52, as shown in FIG. 2, is sealed by the second seal 82 for sealing, and the two seals 81 and 82 are arranged adjacent to each other, in contact with the other by their lips, respectively interior and exterior.
- the seats 51a and 52a form for example one and the same frustoconical seat
- the door elements 71 and 72 form one and the same door with a frustoconical bearing, so that said door can be manipulated in one piece, by an operator located inside or outside of the fixed enclosure 1.
- locking means 58 being provided between the 'door element 72 and the flange 52 of the second closure member 42, the operator must have first made sure that the means 58 are unlocked.
- the coupling of the shutter members 41 and 42, then the opening of the door 71/72 determine the existence in the passage between the enclosures 1 and 2, of two critical lines, one outside on the side of the flanges 51/52, corresponding to the lip of the second seal 82, and the other inside, on the side of the elements of door 71/72, corresponding to the lip of the first seal 81.
- the flexible bag 15 comprises, opposite its bottom 15c, a strip 15d, in a flattened conformation and folded in on itself.
- This strip 15d continually extends the main part 15e of the bag 15, beyond the flange 52, and in doing so determines a flexible envelope 12, closed in a sealed manner by a weld or a sealing means 15f, but openable by the operator .
- this envelope is arranged the essential, if not all of the corresponding closure member 42, that is to say of the closure member of the flexible bag 15, described above.
- the strip 15d comprises a strip 15g linked continuously to the outside of the flange 52, and more precisely to a flange 52b formed on the latter; for this purpose, the strip 15g is held tight against the collar 52b by an external clamping collar 90, heat-shrunk, or heat shrunk, or elastic, etc.
- the strip 15g is itself shaped as a fold, determining an external flank 15gl and an internal flank 15g2, enclosing between them a flexible joint or elastic material 91.
- the continuous and closed connection of itself the strip 15g with the flange 52 makes it possible to seal the interior of the bag 15 from the interior of the protective envelope 12.
- the interior of the protective casing 12 and the interior of the bag 15 are under a partial vacuum, for example having the same value.
- the envelope of protection 12 can be opened before or at the time of coupling of the two shutter members 41 and 42.
- the flexible bag 15 is external, and includes or encloses an internal flexible bag 16, possibly waterproof itself, the wall of which can be essentially common or distinct from the wall of the external bag 15. It is in this inner bag 16 that the load or object 14 is placed, to be transferred to the fixed enclosure 1.
- the flexible inner bag 16 is linked or not, by its end 16b opposite the member d shutter 42, at the bottom 15c of the outer flexible bag 15.
- the inner flexible bag 16 comprises a sleeve 16a, folded back on itself, and thus forming means for closing the bag 16, it being understood that before coupling, and as shown in FIG. 1, the external flexible bag 15 and the internal flexible bag 16 are for example both vacuum-packed.
- the strip 15d of the flexible bag 15, under partial vacuum has a relatively flat shape connecting on one side the mouth 15a proper of the bag 15, and determining on the other side, a folded part 3 pm pressed against the rear face, opposite the shutter member 42.
- This arrangement brings two additional advantages: - after coupling, and before opening the door 71/72, the rear face (this is that is to say on the side of the enclosure 2) of said door is essentially exposed to the pressure of the external environment, through the folded-down zone 15 h; this limits the effort to be exerted to open the door 71/72, taking into account the pressure difference between the enclosures 1 and 2; 10
- this flattened shape constitutes a hinge or ball joint, which moreover makes it easier to orient the main part of the bag 15, relative to the enclosure 1, once the door 71/72 is open, for example for transferring the load 14 by gravity.
