- This sleeve carries a cam 137 of said first means actuator, capable of cooperating with a pin 136 of said final locking means.
- Sleeve 160 has a coupling light 161 or the like and the shaft 138 has a protruding pin 162 extending perpendicular to its axis of rotation and engaged in said coupling light 161.
- each handle By maneuvering each handle from neutral position (figure 8) to the first extreme position, the operator first causes the attachment of the single-use enclosure (by cooperation cam 148 with the flange 170), then, at the end of race, the release of door 122 of enclosure 114 and the unlocking of door 123. After use, the operator maneuver each handle to its other extreme position, and the described coupling allows to lock permanently door 123 of the single-use enclosure before the cam 148 is not released from the flange of the use enclosure unique. The same movement causes the door to lock of enclosure 114 by cams 124B. To clear the single-use enclosure, the operator replaces the handles 121 in neutral position.

Abstract
Description
L'invention concerne un dispositif de jonction étanche entre deux enceintes normalement isolées d'un milieu extérieur et susceptibles d'être mises en communication sans contact, même momentané, avec ledit milieu extérieur.The invention relates to a sealed junction device. between two enclosures normally isolated from an environment outside and likely to be connected without contact, even momentary, with said external medium.
L'invention s'applique plus particulièrement à un tel dispositif de jonction étanche dont les éléments sont répartis entre un conteneur mobile ou transportable constituant l'une des enceintes précitées et une installation fixe conçue pour être isolée en permanence du milieu extérieur et constituant l'autre enceinte précitée, le dispositif de jonction étanche permettant des transferts d'objets ou de fluides entre les deux enceintes sans contamination dudit milieu extérieur ou à partir de celui-ci.The invention applies more particularly to such a waterproof junction device the elements of which are divided between a mobile or transportable container constituting one of the aforementioned enclosures and a fixed installation designed to be permanently isolated from external environment and constituting the other aforementioned enclosure, the waterproof junction device allowing transfers objects or fluids between the two enclosures without contamination of or from said external environment.
On connaít des dispositifs de jonction étanche du genre défini ci-dessus permettant de faire communiquer entre elles deux enceintes étanches, notamment pour des transferts de produits, sans qu'à aucun moment l'étanchéité par rapport au milieu extérieur de chacune des enceintes ou de l'ensemble formé par ces enceintes connectées, ne soit rompue.There are known tight junction devices of the genre defined above to communicate between them two sealed enclosures, in particular for product transfers, without at any time sealing in relation to the external environment of each of the enclosures or of the assembly formed by these connected speakers, broken.
Un tel système met en oeuvre deux portes, chacune d'entre elles obturant hermétiquement une ouverture de l'enceinte correspondante délimitée par une bride annulaire. Les portes sont pourvues de moyens d'assemblage coopérants permettant de les appliquer l'une contre l'autre de façon hermétique, avant la mise en communication, afin d'isoler mutuellement leurs faces externes. Après le transfert d'une enceinte vers l'autre, l'ensemble des deux portes est remis en place dans les logements respectifs prévus dans leurs brides et les deux enceintes sont séparées. De cette façon, les faces externes des deux portes ne peuvent être contaminées ou contaminantes du fait qu'elles s'étaient isolées mutuellement pendant le transfert. Elles peuvent donc à nouveau être mises en contact avec le milieu extérieur. Such a system implements two doors, each of them hermetically sealing an opening of the corresponding enclosure delimited by a flange annular. The doors are provided with assembly means cooperants allowing to apply them one against the other hermetically, before placing in communication, so to mutually isolate their external faces. After the transfer from one enclosure to another, all of the two doors are replaced in the respective housings provided in their flanges and the two enclosures are separated. In this way, the outer faces of the two doors cannot be contaminated or contaminating because that they had isolated each other during the transfer. They can therefore once again be contact with the outside environment.
Un tel système est par exemple décrit dans le brevet français N° 1 346 486. Ce document décrit une solution plus particulièrement applicable dans l'industrie nucléaire. Les enceintes mises en communication sont nécessairement coûteuses, compte tenu de l'application envisagée.Such a system is for example described in the patent French N ° 1 346 486. This document describes a more particularly applicable in the nuclear industry. The ported enclosures are necessarily expensive, given the intended application.
Le document EP 0 586 307 décrit un système de raccordement du même type présentant en outre un mécanisme de commande centralisé dont le fonctionnement est conditionné par plusieurs verrous.The document EP 0 586 307 describes a system of connection of the same type additionally having a mechanism centralized operating system conditioned by several locks.
L'invention concerne un nouveau concept pour de tels dispositifs de jonction étanche entre deux enceintes isolées d'un milieu extérieur, applicable à de nombreux domaines où les produits manipulés sont stériles et doivent être conservés stériles, ou au contraire polluants, voire dangereux, et doivent être manipulés sans communication avec le milieu extérieur.The invention relates to a new concept for such waterproof junction devices between two enclosures isolated from an external environment, applicable to many fields where the products handled are sterile and must be kept sterile, or on the contrary polluting, even dangerous, and must be handled without communication with the outside environment.
Plus précisément, l'invention concerne donc un dispositif de jonction étanche entre deux enceintes isolées d'un milieu extérieur et munies, chacune, d'une porte apte à obturer hermétiquement une ouverture de l'enceinte correspondante délimitée par une bride annulaire, chaque porte étant délimitée avec une face interne au contact de l'intérieur de l'enceinte et avec une face externe au contact dudit milieu extérieur et lesdites portes étant pourvues de moyens d'assemblage coopérants permettant de les appliquer l'une contre l'autre de façon hermétique afin d'isoler mutuellement leurs faces externes, caractérisé en ce que l'une des deux enceintes étant du type à usage unique, elle comporte des moyens de verrouillage final et définitif de sa propre porte, commandés par des premiers moyens d'actionnement installés sur l'autre enceinte. More specifically, the invention therefore relates to a waterproof junction device between two isolated enclosures an external environment and each provided with a suitable door to hermetically seal an opening in the enclosure corresponding delimited by an annular flange, each door being delimited with an internal face in contact with inside the enclosure and with an external face to the contact of said external medium and said doors being provided with cooperative assembly means making it possible to apply them tightly against each other so to mutually isolate their external faces, characterized in one of the two enclosures being of the usage type unique, it includes final locking means and final from his own door, ordered by first actuation means installed on the other enclosure.
L'invention concerne aussi une enceinte à usage unique mise en oeuvre
dans ce dispositif telle que définie dans la revendication 22.The invention also relates to a single-use enclosure used
in this device as defined in
Pour de multiples applications, au moins une partie de la paroi de ladite enceinte à usage unique est en matériau souple et rattachée directement ou indirectement à la bride annulaire rigide sur laquelle est montée la porte correspondante.For multiple applications, at least part of the wall of said single-use enclosure is made of material flexible and attached directly or indirectly to the flange rigid ring on which the door is mounted corresponding.
Dans de nombreux cas, c'est l'enceinte entière, hormis la bride et la porte, qui prendra la forme d'un sac en matériau souple.In many cases, it's the entire enclosure, except the strap and the door, which will take the form of a bag flexible material.
D'autres équipements de sécurité sont avantageusement prévus et en particulier, ladite enceinte à usage unique peut comporter des moyens de verrouillage initial de sa propre porte, agencés pour être inhibés par des seconds moyens d'actionnement installés sur ladite autre enceinte.Other safety equipment is advantageously provided and in particular, said single-use enclosure may include means for initial locking of its own door, arranged to be inhibited by seconds actuating means installed on said other enclosure.
L'invention sera mieux comprise et d'autres avantages de celle-ci apparaítront plus clairement à la lumière de la description qui va suivre d'un mode de réalisation d'un dispositif de jonction étanche conforme à son principe et de plusieurs applications remarquables de ce concept, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés dans lesquels:

En se reportant plus particulièrement aux figures 1 à
7, on a représenté partiellement un dispositif de jonction
étanche 11 établi entre deux enceintes 14, 16, les éléments
constitutifs du dispositif en question étant portés pour
partie par l'enceinte 14, qui est ici un conteneur ou un
local ou toute autre installation fixe, conçu pour être
isolé en permanence du milieu extérieur et pour partie par
l'enceinte 16 qui est ici un simple conteneur de capacité
relativement faible comparée à celle de l'enceinte 14. Il
est important de noter que l'enceinte 16 est conçue en tant
qu'enceinte à usage unique. Plus précisément, les deux
enceintes 14 et 16 comportent chacune une ouverture 18, 20
délimitée par une bride annulaire 18a, 20a, respectivement.
Chaque ouverture 18, 20 est munie d'une porte 22, 23,
respectivement. Dans l'exemple, les brides ont un contour
circulaire, mais cela n'est nullement impératif. Le
dispositif de jonction étanche est conçu pour gérer
l'assemblage et la séparation des portes 22, 23 et la mise
en communication des deux enceintes selon une procédure
évitant tout contact du contenu de l'une ou l'autre
enceinte avec le milieu extérieur. Ainsi, la porte 22 de
l'enceinte 14 est définie avec une face interne 22a
normalement au contact de l'intérieur de l'enceinte 14 et,
en tout cas, jamais au contact du milieu extérieur tandis
que la porte 23 de l'enceinte 16 est définie avec une face
interne 23a normalement au contact de l'intérieur de
l'enceinte 16 et en tout cas jamais au contact du milieu
extérieur. De façon similaire, la porte 22 est définie avec
une face extérieure 22b normalement au contact du milieu
extérieur et en tout cas jamais au contact de l'intérieur
de l'une ou l'autre enceinte tandis que la porte 23 est
définie avec une face extérieure 23b normalement au contact
du milieu extérieur et en tout cas jamais au contact de
l'intérieur de l'une ou l'autre enceinte. Pour ce faire,
les deux portes sont pourvues de moyens d'assemblage
coopérants permettant de les assembler l'une contre l'autre
de façon hermétique afin d'isoler mutuellement leurs faces
externes 22b, 23b. Ainsi l'une des portes, ici la porte 22
est munie d'un joint annulaire 26 en matériau élastomère
sur lequel vient s'appliquer un bord externe saillant de la
porte 23. De plus, la bride 20a de l'enceinte à usage
unique 16 est pourvue à sa périphérie d'un joint annulaire
27 venant s'appliquer sur le bord de la bride 18a de
l'enceinte 14, au voisinage immédiat du joint 26. Des
éléments de solidarisation 28 fonctionnant ici par simple
contact sont respectivement solidaires des faces externes
22b, 23b, aux centres de celles-ci. Ces éléments de
solidarisation 28 sont par exemple des plaquettes
magnétiques ou adhésives ou des moyens utilisant des
ventouses ou d'autres éléments analogues. Chaque plaquette
fixée au centre d'une porte est susceptible de venir se
coller contre l'autre. On pourrait aussi remplacer ces
éléments par des systèmes mécaniques, par exemple à
crochets. D'autre part, lesdits moyens d'assemblage sont
complétés par des mécanismes à cames 25 agencés au bord de
l'ouverture de l'enceinte 14. On a prévu trois mécanismes
de ce genre répartis à 120° le long de l'ouverture 18.
Chaque mécanisme comporte un arbre 24 monté tournant dans
l'épaisseur de la bride 18a et deux cames 24A, 24B,
respectivement extérieure et intérieure à angles d'action
décalés angulairement. La came extérieure 24A permet
d'assujettir la bride 20a de l'enceinte à usage unique à
celle 18a de l'enceinte 14 tandis que la came intérieure 24B
permet d'assujettir la porte 22 de l'enceinte 14 à la bride
18a de celle-ci. Chaque arbre portant les deux cames
précitées est muni d'une poignée de manoeuvre 21. La bride
20a comporte une collerette annulaire 17 extérieure munie
de trois échancrures 17a, radiales où les cames extérieures
24A viennent se loger lorsqu'on approche la bride 20a de la
bride 18a. Dans cette situation, les cames extérieures 24A
s'étendent sensiblement radialement et, comme on le voit,
les cames intérieures 24B sont dans une position telle
qu'elles maintiennent fermement la porte 22 en application
contre son siège défini dans la bride 18a. Les cames
intérieures 24B comportent des méplats 15 tels que
lorsqu'on fait tourner les poignées, on réalise d'abord une
solidarisation de la collerette extérieure 17 de la bride
20a contre la bride 18a, avant de libérer la porte 22 par
dégagement des cames intérieures.Referring more particularly to Figures 1 to 7, there is partially shown a
Il ressort clairement de ce qui précède que, dès lors
qu'on commence à raccorder les deux ouvertures, on applique
les deux portes l'une contre l'autre, de façon hermétique,
sans rotation de l'une par rapport à l'autre et de telle
sorte que les deux faces extérieures 22b, 23b qui étaient
en contact avec le milieu extérieur, s'isolent mutuellement
en ne laissant subsister entre elles qu'un espace laminaire
29 hermétiquement clos (figure 6). Les deux faces 22b, 23b
s'isolent de cette façon et les portes restent assemblées
tout en pouvant être dégagées ensemble de leurs sièges, de
sorte que des échanges deviennent possibles entre les deux
enceintes. A la fin de ces opérations, les deux portes sont
remises en place ensemble dans leurs ouvertures
respectives, avant d'être réassemblées à leurs brides
respectives puis séparées.It is clear from the above that, as soon as one begins to connect the two openings, the two doors are applied one against the other, in a hermetic manner, without rotation of one with respect to the other and so that the two
Comme on l'a indiqué précédemment, l'enceinte 16 est
du type à usage unique et de ce fait elle comporte des
moyens de verrouillage final de sa propre porte 23,
commandés par des premiers moyens d'actionnement installés
sur l'autre enceinte. Plus précisément, lesdits moyens de
verrouillage final comportent au moins un agencement 30
défini dans la porte 23 et la bride 20a et comprenant un
trou 32 traversant la bride 20a, un trou borgne 34
s'étendant dans l'épaisseur de la porte 23 de l'enceinte à
usage unique 16, normalement dans le prolongement du trou
32 de la bride et une goupille 36 ou analogue, engagée dans
le trou 32 et ayant une longueur supérieure à l'épaisseur
de la bride 20a. Comme cela est visible sur la figure 1, on
a prévu deux agencements 30 de ce genre, diamétralement
opposés. Avant mise en oeuvre desdits moyens de
verrouillage final, ladite goupille 36 fait saillie à
l'extérieur de la bride 20a et n'est pas engagée dans le
trou borgne 34.As previously indicated, the
Par ailleurs, lesdits premiers moyens d'actionnement
comportent, au voisinage de chaque goupille 36, un élément
38 formant arbre, monté pivotant autour de son propre axe
dans la bride 18a, près du bord de l'ouverture 18 de
l'enceinte 14. Cet arbre est équipé d'une came 37 apte à
coopérer avec la goupille 36 voisine et l'enfoncer dans le
trou borgne 34. Cet élément 38 est muni d'un levier 39
permettant de manoeuvrer la came 37. En outre, l'enceinte à
usage unique 16 comporte aussi des moyens de verrouillage
initial de sa propre porte 23, agencés pour être inhibés
par des seconds moyens d'actionnement installés sur
l'enceinte 14. Ces moyens de verrouillage initial
comportent au moins un agencement 40 défini dans la porte
23 et la bride 20a et comprenant un trou 42 traversant la
bride 20a, un trou borgne 44 s'étendant dans l'épaisseur de
la porte 23 de l'enceinte à usage unique 16, normalement
dans le prolongement du trou 42 de la bride et deux
goupilles ou analogues, respectivement une goupille interne
46 et une goupille externe 47 engagées dans le prolongement
l'une de l'autre, dans ces deux trous. Comme précédemment,
on a prévu deux agencements 40, diamétralement opposés.Furthermore, said first actuation means comprise, in the vicinity of each pin 36, an
Avant utilisation de l'enceinte à usage unique, la
goupille interne 46 est engagée à la fois dans la bride 20a
et dans la porte 23 tandis que la goupille externe 47 fait
saillie hors de la bride 20a (figure 3). Les longueurs des
goupilles 46, 47 sont telles que leurs extrémités en
contact puissent venir se placer à l'interface de la bride
20a et de la porte 23 (figure 4) lorsque lesdits seconds
moyens d'actionnement s'exercent sur la goupille externe
47. Ces seconds moyens d'actionnement comportent une came
48 apte à coopérer avec la goupille 47 pour l'enfoncer dans
la bride 20a (figure 4). Cette came est solidaire du même
élément 38 formant arbre, muni du levier 39. Autrement
dit, comme cela apparaít clairement sur les figures 1 et 3
à 5, lesdits premier et second moyens d'actionnement sont
combinés et répartis sur deux ensembles diamétralement
opposés. A ces emplacements, la collerette 17 est pourvue
de découpes pour accueillir les éléments 38 et les cames
37, 48 correspondantes. Les goupilles sont montées de façon
à garantir un contact hermétique avec les parois des trous
dans lesquels elles sont installées, formant des sortes de
bouchons.Before using the single-use enclosure, the internal pin 46 is engaged both in the
Comme on le voit sur la figure 6, les champs des
brides 18a, 20a et ceux des portes 22, 23 qui se montent
respectivement dans celles-ci sont coniques ou comportent
des portions coniques. Les parties coniques des brides
forment ainsi des sièges annulaires pour lesdites portes.
Lesdites parties coniques ont la même conicité et les
diamètres des faces extérieures 22b, 23b sont égaux de
sorte qu'une fois assemblées, les portes ne présentent
qu'une seule partie conique sans solution de continuité. De
même, les extrémités des brides destinées à venir en
contact ont des diamètres égaux de sorte que les parties
coniques des brides se trouvent dans le prolongement l'une
de l'autre après assemblage et ne forment qu'un seul
tronçon conique sans solution de continuité. Cette
configuration particulière des champs des brides et des
portes facilitent le dégagement et la remise en place de la
double porte.As can be seen in FIG. 6, the fields of the
Le positionnement circonférentiel précis de la bride
20a par rapport à la bride 18a est assuré par trois pions
50 solidaires de la bride 18a et répartis
circonférentiellement à 120°, coopérant avec des
échancrures 51 pratiquées dans la collerette 17. L'un des
pions 50 au moins traverse la paroi de la bride 18a et
s'étend à l'intérieur de l'enceinte 14. Une collerette
périphérique de la porte 22 comporte un trou 51 ou une
découpe analogue, susceptible d'assurer un positionnement
circonférentiel précis des deux portes par rapport aux
brides assemblées lorsqu'on remet les deux portes en place
avant de procéder aux opérations de séparation des deux
enceintes. On est ainsi assuré de replacer les deux trous
32 et 34 de chaque agencement 30 dans le prolongement l'un
de l'autre (figure 5) en vue du verrouillage final et
définitif de la porte 23 sur la bride 20a de l'enceinte à
usage unique 16. La remise en position des deux portes peut
être facilitée si l'enceinte 14 est munie d'une manche en
matériau souple placée sur le côté de l'ouverture 18 et par
laquelle un opérateur peut introduire son bras et
manoeuvrer à l'intérieur de l'enceinte 16. La bride 18a est
aussi munie d'un levier 54 dont une extrémité est engagée
sous la collerette 17 (figure 7) à l'assemblage des deux
enceintes, en vue de faciliter ultérieurement le
décollement des deux brides, à la séparation desdites
enceintes.The precise circumferential positioning of the
Selon une autre caractéristique très avantageuse de
l'invention, l'enceinte 16 à usage unique ou au moins une
partie de celle-ci est en matériau souple. La partie en
matériau souple est rattachée à la bride annulaire rigide
20a sur laquelle est montée la porte 23. Dans plusieurs
modes de réalisation, l'enceinte 16 peut consister en un
simple sac de matériau souple raccordé, par exemple soudé,
à la bride 20a (voir figure 6). L'ensemble de l'enceinte 16
est constitué par des éléments en matériau peu coûteux. Par
exemple, la bride 20a et la porte 23 peuvent être en
matière plastique rigide et le reste de l'enceinte (formant
le sac souple) peut être en matière plastique souple.According to another very advantageous characteristic of the invention, the single-
On va maintenant décrire en référence aux figures 3 à 5, les opérations permettant d'accoupler et désaccoupler les deux enceintes.We will now describe with reference to FIGS. 3 to 5, the operations for coupling and uncoupling the two speakers.
Avant utilisation, les agencements 30 et 40 de
l'enceinte à usage unique ont la configuration illustrée à
la figure 3. Lorsque le levier 39 est orienté radialement,
rien ne s'oppose au positionnement de la bride 20a sur la
bride 18a et à l'assemblage des deux portes 22, 23.
Cependant la position des goupilles 46 empêche l'ouverture
de la porte 23. Avant toute autre manoeuvre, l'opérateur
actionne les trois mécanismes à cames 25 ce qui a pour
conséquence d'assujettir fermement la bride 20a sur la
bride 18a et ensuite de déverrouiller la porte 22. Ensuite,
l'opérateur fait pivoter les deux leviers 39 pour passer
de la situation illustrée à la figure 3 à celle représentée
à la figure 4. A partir de ce moment, le point de contact
entre les deux goupilles 46 et 47 se trouve à l'interface
de la bride 20a et de la porte 23 et cette dernière peut
être désolidarisée de la bride 20a en même temps que la
porte 22 avec laquelle elle est assemblée. On peut alors
effectuer les opérations souhaitées et notamment les
transferts entre les deux enceintes. Après quoi, les deux
portes 22 et 23, toujours assemblées, sont remises en
place, et l'opérateur fait à nouveau pivoter les poignées
39 pour amener les cames 37 dans la position illustrée à la
figure 5, ce qui aboutit à l'enfoncement des goupilles 36
et au verrouillage définitif de la porte 23 sur la bride
20a de l'enceinte 16. Après quoi, il suffit à nouveau de
manoeuvrer les mécanismes à cames 25 pour séparer les deux
enceintes, chacune étant à nouveau fermée par sa propre
porte.Before use, the
Les figures 8 à 10 illustrent une variante dans
laquelle les éléments de structure analogues à ceux des
figures 1 à 5 portent les mêmes références numériques
augmentées de 100. Ce mode de réalisation se distingue du
précédent par le fait que les moyens d'assemblage,
notamment les mécanismes à cames 125 sont combinés auxdits
premiers moyens d'actionnement comportant une came 137 et
auxdits seconds moyens d'actionnement comportant une came
148. De cette façon, les opérations de raccordement et de
verrouillage-déverrouillage sont simplifiées et les risques
d'erreur de manoeuvre sont considérablement réduits.Figures 8 to 10 illustrate a variant in
which structural elements similar to those of
Figures 1 to 5 have the same reference numbers
increased by 100. This embodiment differs from
precedent by the fact that the assembly means,
in particular the
Plus précisément, selon l'exemple, les mécanismes à
cames représentés sur la figure 1 sont ramenés à deux et
regroupés avec les arbres 138 et les poignées de manoeuvre 121 desdits
premiers et seconds moyens d'actionnement déjà combinés
dans l'exemple précédent.More precisely, according to the example, the mechanisms to
cams shown in Figure 1 are reduced to two and
grouped with the
Les cames intérieures 137 et extérieures 148 que comportaient
lesdits moyens d'assemblage sont reportés sur les arbres
138, une came intérieure 124B étant installée à l'extrémité
intérieure de chacun d'eux et les cames extérieures étant
ici confondues avec les cames 148 desdits seconds moyens
d'actionnement des moyens de verrouillage initial 140
précités. Les cames 148 (ou 124A) et 124B sont solidaires
de l'arbre 138 et ont des angles d'action décalés
angulairement comme dans l'exemple précédent, pour assurer
les mêmes fonctions. Les cames extérieures 124A permettent
d'assujettir la bride 120a de l'enceinte à usage unique 116 à
celle de ladite autre enceinte 114 tandis que les cames
intérieures 124B permettent d'assujettir la porte de
l'enceinte 114 à la bride 118a de celle-ci.The inner 137 and outer 148 cams that included
said assembly means are transferred to the
Par ailleurs, les cames 148 sont susceptibles de
coopérer en fin de course, dans un sens de rotation des
poignées de manoeuvre 121, avec les goupilles 142 desdits
moyens de verrouillage initial.Furthermore, the
Cependant, chaque poignée de manoeuvre 121 n'est pas
directement liée à l'arbre 138 correspondant; elle est
solidaire d'un manchon de manoeuvre 160 qui coiffe l'arbre
138. Ce manchon porte une came 137 desdits premiers moyens
d'actionnement, susceptible de coopérer avec une goupille
136 desdits moyens de verrouillage final. Le manchon 160
comporte une lumière de couplage 161 ou analogue et l'arbre
138 comporte un pion 162 en saillie, s'étendant
perpendiculairement à son axe de rotation et engagé dans
ladite lumière de couplage 161. Avec cet agencement
particulier, chaque poignée 121 est susceptible de prendre
une position neutre et deux positions extrêmes
correspondant respectivement au déverrouillage de la porte
123 puis à son verrouillage final. En manoeuvrant chaque
poignée de la position neutre (figure 8) à la première
position extrême, l'opérateur provoque d'abord le
rattachement de l'enceinte à usage unique (par coopération
de la came 148 avec la collerette 170), puis, en fin de
course, la libération de la porte 122 de l'enceinte 114 et le
déverrouillage de la porte 123. Après usage, l'opérateur
manoeuvre chaque poignée vers son autre position extrême,
et le couplage décrit permet de verrouiller définitivement
la porte 123 de l'enceinte à usage unique avant que la came
148 ne soit dégagée de la bride de l'enceinte à usage
unique. Le même mouvement entraíne le blocage de la porte
de l'enceinte 114 par les cames 124B. Pour dégager
l'enceinte à usage unique, l'opérateur replace les poignées
121 en position neutre.However, each operating
Les figures 11 à 22 illustrent des enceintes 16 mobiles à
usage unique, le plus souvent avec une paroi ou une partie
de paroi souple et avec des caractéristiques et/ou des
équipements particuliers donnant à l'enceinte une fonction
propre. Dans ces figures, les éléments de structure
analogues à ceux décrits en référence aux figures 1 à 7
portent les mêmes références numériques. Ainsi, la figure
11 représente dans son ensemble une enceinte à usage unique
16 à paroi souple en forme de sac étanche raccordé à la
bride, cette dernière étant refermée par la porte 23. Bien
entendu, la bride et la porte sont équipées des goupilles
permettant d'abord le déverrouillage initial et
ultérieurement le verrouillage final et définitif. La
partie en matériau souple formant sac peut être en matière
plastique parfaitement étanche, notamment si l'enceinte est
destinée à recevoir des produits contaminés ou polluants et
si elle est destinée à être détruite, par exemple par
incinération, avec son contenu. La paroi peut également
être poreuse, ce qui permet de réaliser une stérilisation
par autoclavage avant ou après utilisation.Figures 11 to 22 illustrate
Selon une autre variante le sac raccordé à la bride est en matériau hydrosoluble. On peut ainsi récupérer des vêtements sales et/ou contaminés, les placer dans l'enceinte à usage unique et introduire celle-ci dans une machine à laver. Le sac hydrosoluble s'y dissout au début du lavage et on peut récupérer les vêtements propres à la fin du cycle de lavage.According to another variant, the bag connected to the flange is made of water-soluble material. We can thus recover dirty and / or contaminated clothes, place them in the single-use enclosure and introduce it into a washing machine. The water-soluble bag dissolves there at the start washing and we can collect clothes clean for the end of the washing cycle.
Le mode de réalisation de la figure 12 est semblable à
celui de la figure 11 mais une partie 16a seulement de la
paroi souple est réalisée dans un matériau poreux apte à
permettre une stérilisation par imprégnation d'un gaz tel
que l'oxyde d'éthylène. La stérilisation se fait en plaçant
l'enceinte dans une atmosphère d'oxyde d'éthylène sous
pression.The embodiment of Figure 12 is similar to that of Figure 11 but a
Le mode de réalisation de la figure 13 permet
également une stérilisation par oxyde d'éthylène. Dans ce
cas, ladite enceinte à usage unique comporte un embout de
raccordement 50 pour sa jonction à une source d'oxyde
d'éthylène gazeux ou à une autre source de gaz de
stérilisation. Un filtre à membrane 51 est intercalé entre
l'embout 50 et le volume interne de l'enceinte 16. Ce
filtre forme en même temps un obturateur qui empêche une
contamination ultérieure du volume intérieur de l'enceinte.The embodiment of Figure 13 allows
also sterilization with ethylene oxide. In this
case, said single-use enclosure has a
Dans l'exemple de la figure 14, l'enceinte à usage
unique est constituée d'une partie en matériau souple 16b
et d'un bocal rigide 53. La partie en matériau souple se
raccorde de façon étanche au bocal d'une part et à la bride
20a d'autre part. On peut ainsi récupérer des objets
tranchants ou pointus (bistouris, seringues, etc...) sans
risque de perforation de l'enceinte à usage unique.In the example of FIG. 14, the single-use enclosure consists of a part made of
L'exemple de la figure 15 est celui d'un sac 55
renfermant de la poudre. La partie en matériau souple
comporte au moins un manchon tubulaire 56 raccordé entre la
bride d'une part et le sac d'autre part. Il est également
possible que cette partie soit un sac comme dans l'exemple
de la figure 8 renfermant un autre sac, ce dernier
contenant la poudre. Dans les deux cas, l'enceinte à usage
unique ou le sac intérieur comporte une manche intérieure
57 en matériau souple qui permet de déverser facilement la
poudre. Dans cet exemple, il est à noter que, du fait que
la partie qui contient la poudre est raccordée à la bride
par le manchon en matériau souple, on peut effectuer le
raccordement à l'enceinte fixe sans être gêné par le poids,
souvent important, du sac de poudre.The example in Figure 15 is that of a
La figure 16 illustre un autre mode de réalisation
permettant de transférer une solution stérilisable par
filtration. Pour ce faire, la paroi de l'enceinte à usage
unique 16 est traversée de façon hermétique par une
tubulure de raccordement 59 et un filtre 60, raccordé à
cette tubulure, est logé dans ladite enceinte à usage
unique. On peut donc raccorder cette enceinte à une autre
enceinte fixe contenant le produit liquide à stériliser par
filtration, extraire ce produit en le filtrant et jeter
et/ou détruire le filtre 60 dans ladite enceinte à usage
unique, après le transfert.Figure 16 illustrates another embodiment
for transferring a sterilizable solution by

La figure 17 illustre un autre mode de réalisation
comportant deux brides 20a munies de portes 23 respectives
et respectivement raccordables à d'autres enceintes 14.
Dans l'exemple de la figure 17, les deux parties sont
reliées par un tube 63 qui forme un élément d'un circuit
fluidique. Grâce à cet agencement, on peut ainsi établir
une circulation de fluide entre deux enceintes normalement
isolées l'une de l'autre, la double enceinte à usage unique
renfermant le tube de raccordement 63 étant destinée à être
détruite après usage.FIG. 17 illustrates another embodiment comprising two
L'exemple de la figure 18 montre également une
enceinte à usage unique comportant deux brides 20a munies
de portes 23 respectives, raccordables à d'autres enceintes
fixes. Dans cet exemple, la partie en matériau souple est
connectée aux deux brides par ses extrémités respectives de
sorte qu'on définit ainsi un manchon de communication 65
entre les deux enceintes fixes.The example in FIG. 18 also shows a single-use enclosure comprising two
Dans l'exemple de la figure 19, l'enceinte à usage
unique comporte un élément de conduit souple 68 dont les
deux extrémités débouchent à l'intérieur du sac en matériau
souple. Un tronçon en U dudit élément de conduit s'étend à
l'extérieur de ce sac. Ce dispositif réalise un élément de
pompe péristaltique jetable. En effet, les deux extrémités
du conduit souple peuvent être connectées à deux parties
d'un circuit établi à l'intérieur de l'enceinte fixe tandis
qu'il est possible de coupler le moteur et les excentriques
de la pompe péristaltique à la partie du conduit souple qui
s'étend à l'extérieur du sac. Après usage, les deux
extrémités du conduit souple se retrouvent confinées à
l'intérieur de l'enceinte à usage unique et l'ensemble peut
être détruit.In the example of figure 19, the enclosure for use
single comprises a
La figure 20 décrit une enceinte à usage unique qui
n'est pas munie d'une paroi en matériau souple mais qui
constitue un filtre à air ou plus généralement un filtre de
gaz à usage unique, destiné à être raccordé à une enceinte
fixe. La bride 20a est raccordée par une tubulure rigide 69
à un boítier 70 renfermant un filtre sec 71, du genre
filtre à air, faible pression.FIG. 20 describes a single-use enclosure which is not provided with a wall made of flexible material but which constitutes an air filter or more generally a single-use gas filter, intended to be connected to a fixed enclosure. The
Les figures 21 et 22 illustrent un dernier mode de
réalisation dans lequel la partie en matériau souple de
l'enceinte à usage unique est constituée par un gant 73
retourné (figure 21) raccordé par la manche à une bride
20a munie de sa porte 23. Lorsqu'un tel dispositif est
assemblé à l'ouverture d'une autre enceinte fixe 14,
l'utilisateur peut introduire sa main dans le gant 73 et
l'engager dans l'enceinte fixe (figure 22) pour y procéder
à des manipulations.Figures 21 and 22 illustrate a last embodiment in which the flexible material part of the single-use enclosure consists of an inverted glove 73 (Figure 21) connected by the sleeve to a
