Abstract

Ce dispositif comporte un support (14) muni d'un siège semi-cylindrique (15) destiné à recevoir un segment (12) de tubulure. Ce segment (12) porte une collerette (17) semi-circulaire inclinée par rapport à l'axe de la tubulure et destinée à pénètrer dans une rainure (16) présentant la même inclinaison que la collerette (17) par rapport à l'axe du siège semi-cylindrique (15). De ce fait, lorsqu'une force de traction est exercée par la pompe sur la partie (13) de la tubulure, et que la collerette (17) est engagée dans la rainure (16), cette force tend à appliquer le segment (12) contre le siège (15) et provoque l'auto-blocage de l'assemblage.This device comprises a support (14) provided with a semi-cylindrical seat (15) intended to receive a segment (12) of tubing. This segment (12) carries a semi-circular flange (17) inclined with respect to the axis of the pipe and intended to penetrate into a groove (16) having the same inclination as the flange (17) with respect to the axis of the semi-cylindrical seat (15). Therefore, when a tensile force is exerted by the pump on the part (13) of the tubing, and the collar (17) is engaged in the groove (16), this force tends to apply the segment (12 ) against the seat (15) and causes the self-locking of the assembly.

Description

La présente invention se rapporte à un dispositif d'assemblage d'une tubulure sur une pompe péristaltique, comprenant un support présentant un siège ouvert latéralement et dont la forme est complémentaire de celle d'une portion de la tubulure, cette dernière portant un élément de butée axiale destiné à être appliqué contre une face dudit support coupant l'axe dudit siège, pour retenir cette tubulure axialement sur ce support à l'encontre de la force de traction exercée par la pompe péristaltique sur la tubulure.The present invention relates to a device for assembling a tubing on a peristaltic pump, comprising a support having a seat open laterally and whose shape is complementary to that of a portion of the tubing, the latter carrying an element of axial stop intended to be applied against a face of said support intersecting the axis of said seat, for retaining this tubing axially on this support against the tensile force exerted by the peristaltic pump on the tubing.

Ce dispositif d'assemblage comporte généralement un support dans lequel est ménagé un siège semi-cylindrique auquel on peut accéder latéralement par une ouverture parallèle à l'axe longitudinal du siège, mais dont la largeur est inférieure au diamètre de la section de ce siège. Pour introduire la portion de tubulure dans ce siège, il faut légèrement l'écraser jusqu'à ce qu'elle arrive dans la partie semi-cylindrique où la tubulure peut alors reprendre sa forme initiale sous l'effet de son élasticité propre. L'ouverture d'accès au siège a une largeur inférieure au diamètre de ce siège pour empêcher la sortie accidentelle de ce tube. En effet, sous l'action de pincement et de relâchement que les galets de la pompe péristaltique exercent sur une portion de la tubulure, celle-ci pourrait accidentellement sortir de son siège. Etant donné par ailleurs que les galets de la pompe exercent une force de traction sur la tubulure, celle-ci comporte encore une collerette qui s'appuie contre une face du support orientée transversalement au siège.This assembly device generally comprises a support in which is formed a semi-cylindrical seat which can be accessed laterally by an opening parallel to the longitudinal axis of the seat, but whose width is less than the diameter of the section of this seat. To introduce the portion of tubing into this seat, it should be slightly crushed until it arrives in the semi-cylindrical part where the tubing can then return to its original shape under the effect of its own elasticity. The seat access opening has a width less than the diameter of this seat to prevent the accidental exit of this tube. Indeed, under the pinching and loosening action that the rollers of the peristaltic pump exert on a portion of the tubing, the latter could accidentally come out of its seat. Since, moreover, the rollers of the pump exert a tensile force on the tubing, the latter also comprises a collar which bears against a face of the support oriented transversely to the seat.

Ce dispositif d'assemblage comporte divers inconvénients. La mise en place de la tubulure dans le siège de son support nécessite comme on l'a dit un écrasement du tube. Cette opération n'est pas toujours aisée à réaliser, ceci d'autant plus que la collerette qui coopère avec le support est généralement moulée, de sorte que l'on ne peut écraser qu'une partie suffisamment souple de cette tubulure distante donc de cette collerette et qu'ensuite il faut la faire coulisser dans le siège pour l'amener en butée contre la face d'appui transversale du support. Un autre inconvénient de ce dispositif d'assemblage provient du fait que rien ne s'oppose à l'inversion de la tubulure lors du montage. Il faut en effet savoir qu'une telle tubulure est généralement formée de divers segments assemblés les uns aux autres, chaque segment étant fait en une matière plastique appropriée à sa fonction. C'est ainsi que le segment qui doit être associé au sabot et aux galets d'écrasement de la pompe péristaltique a des propriétés bien définies, de sorte qu'une inversion nuirait au bon fonctionnement. Il existe également des applications dans lesquelles deux conduits distincts aboutissent à l'extrémité amont de la pompe par un branchement en Y, des valves de commande servant à mettre sélectivement l'un ou l'autre de ces conduits en communication avec la pompe. Il est évident, dans ce cas, que chaque conduit a une fonction distincte et, par conséquent, les bran-ches de l'Y associées à chacun de ces conduits ne doivent pas être inversées. Or, le dispositif d'assemblage susmentionné ne permet pas de déterminer la position de ces deux branches et l'utilisateur doit lui-même s'assurer que les branches respectives sont reliées aux fonctions correctes.This assembly device has various drawbacks. The installation of the tubing in the seat of its support requires, as has been said, a crushing of the tube. This operation is not always easy to carry out, all the more so since the collar which cooperates with the support is generally molded, so that only a sufficiently flexible part of this tubing which is distant from this can be crushed. bezel and then slide it into the seat to bring it into abutment against the transverse bearing face of the support. Another drawback of this assembly device comes from the fact that nothing prevents the reversal of the tubing during assembly. It should indeed be known that such a tube is generally formed of various segments assembled to each other, each segment being made of a plastic material suitable for its function. This is how the segment which must be associated with the shoe and the crushing rollers of the peristaltic pump has well defined properties, so that an inversion would adversely affect the proper functioning. There are also applications in which two separate conduits terminate at the upstream end of the pump by a Y connection, control valves serving to selectively put one or the other of these conduits in communication with the pump. It is obvious, in this case, that each conduit has a distinct function and, therefore, the branches of the Y associated with each of these conduits must not be reversed. However, the above-mentioned assembly device does not make it possible to determine the position of these two branches and the user must himself ensure that the respective branches are connected to the correct functions.

Cette question du montage de la tubulure prend une importance particulière, notamment dans le domaine médical, étant donné que cette tubulure doit alors être changée à chaque intervention. Il devient de ce fait évident que les inconvénients susmentionnés prennent une importance accrue compte tenu de la fréquence de cette opération de montage et des répercussions que peut avoir toute erreur commise dans ce domaine.This question of fitting the tubing takes on particular importance, particularly in the medical field, since this tubing must then be changed at each intervention. It therefore becomes obvious that the aforementioned drawbacks take on greater importance in view of the frequency of this mounting operation and the repercussions that any error made in this area may have.

Le but de la présente invention est de remédier, au moins en partie, aux inconvénients susmentionnés.The object of the present invention is to remedy, at least in part, the above-mentioned drawbacks.

A cet effet, cette invention a pour objet un dispositif d'assemblage d'une tubulure sur une pompe péristaltique selon la revendication 1.To this end, the subject of this invention is a device for assembling a tubing on a peristaltic pump according to claim 1.

Le dessins annexé illustre, schématiquement et à titre d'exemple, une forme d'exécution du dispositif d'assemblage objet de la présente invention.The appended drawings illustrate, schematically and by way of example, an embodiment of the assembly device which is the subject of the present invention.

La figure 1 est une vue de face d'une pompe péristaltique et du dispositif d'assemblage.Figure 1 is a front view of a peristaltic pump and the assembly device.

La figure 2 est une vue selon la ligne II-II de la figure 1.Figure 2 is a view along line II-II of Figure 1.

La figure 3 est une vue en perspective montrant le dispositif en deux parties séparées.Figure 3 is a perspective view showing the device in two separate parts.

La figure 1 illustre une tubulure 1 comprenant deux conduits 2 et 3 reliés par un branchement en Y 4 à un conduit commun 5 qui se trouve en amont d'une pompe péristaltique dont on n'a représenté sur cette figure que les parties nécessaires à la compréhension de l'invention, à savoir un mobile 6 porteur de galets 7 répartis circulairement autour de l'axe de rotation 8 du mobile 6 et un sabot 9 monté pivotant autour d'un axe 10, le tout solidaire d'un bâti B. Ce sabot 9 présente une surface semi-circulaire 11 concentrique au mobile 6. Un ressort 1 (non représenté) sert à maintenir élastiquement ce sabot 9 dans une position déterminée par rapport au mobile 6. Un segment 13 de la tubulure 1 est placé entre la surface semi-circulaire 11 du sabot 9 et le mobile 6. L'écartement entre le mobile 6 et le sabot 9 est choisi de manière que chaque galet 7 comprime jointivement une portion de la paroi du segment 13 au fur et à mesure du déplacement du galet 7 dans le sens de la flèche F, en face de la surface semi-circulaire 11 du sabot 9. La longueur de cette surface 11 étant supérieure à l'écartement entre deux galets, il s'ensuit, selon le mode d'entraînement péristaltique bien connu, qu'un volume de liquide est ainsi avancé dans le sens de la flèche F par chaque galet 7 qui se déplace le long de la surface semi-circulaire 11.FIG. 1 illustrates a tube 1 comprising two conduits 2 and 3 connected by a Y connection 4 to a common conduit 5 which is located upstream of a peristaltic pump of which only this part has been shown in this figure. understanding of the invention, namely a mobile 6 bearing rollers 7 distributed circularly around the axis of rotation 8 of the mobile 6 and a shoe 9 mounted pivoting about an axis 10, all integral with a frame B. This shoe 9 has a semi-circular surface 11 concentric with the mobile 6. A spring 1 (not shown) is used to elastically maintain this shoe 9 in a determined position relative to the mobile 6. A segment 13 of the tubing 1 is placed between the semicircular surface 11 of the shoe 9 and the shoe 6. The spacing between the mobile 6 and the shoe 9 is chosen so that each roller 7 compressively joins a portion of the wall of the segment 13 as the displacement of the roller 7 in the direction of the arrow F, opposite the semi-circular surface 11 of the shoe 9. The length of this surface 11 being greater than the spacing between two rollers, it follows, according to the well-known peristaltic drive mode, that a volume of liquid is thus advanced in the direction of arrow F by each roller 7 which moves along the semi-circular surface 11.

Un organe de support 14 est fixé au bâti B du côté amont de la pompe péristaltique. Ce support 14 est agencé pour permettre l'assemblage de la tubulure 1 et comporte à cet effet un siège semi-cylindrique 15 dont le diamètre correspond à celui de la portion de tubulure que ce siège doit recevoir. Ce support 14 qui est de forme généralement parallélipipédique est coupé par une face oblique 14a qui coupe le siège semi-cylindrique 15. Une rainure 16 s'étend perpendiculairement à cette face oblique 14a, traverse le siège semi-cylindrique 15 et pénètre dans le support 14, comme illustré par les figures 2 et 3. Cette même figure montre que la partie de la tubulure 12 qui s'ajuste dans le siège semi-cylindrique 15 sert de raccord aux segments 5 et 13 et comporte une demi-collerette 17 semi-circulaire qui forme, avec l'axe longitudinal des segments de tubulure 5 et 13, le même angle aigu que celui entre la rainure 16 et l'axe longitudinal du siège semi-cylindrique 15.A support member 14 is fixed to the frame B on the upstream side of the peristaltic pump. This support 14 is arranged to allow the assembly of the tubing 1 and for this purpose comprises a semi-cylindrical seat 15 whose diameter corresponds to that of the portion of tubing that this seat must receive. This support 14 which is generally rectangular in shape is cut by an oblique face 14a which cuts the semi-cylindrical seat 15. A groove 16 extends perpendicular to this oblique face 14a, passes through the semi-cylindrical seat 15 and enters the support 14, as illustrated by FIGS. 2 and 3. This same figure shows that the part of the tubing 12 which adjusts in the semi-cylindrical seat 15 serves as a connection to the segments 5 and 13 and comprises a semi-circular half-flange 17 which forms, with the longitudinal axis of the tubing segments 5 and 13, the same acute angle as that between the groove 16 and the longitudinal axis of the semi-cylindrical seat 15.

Comme on le voit sur les figures 1 et 2, la demi-collerette 17 s'engage dans la rainure 16 lorsque la partie de tubulure 5 est placée dans le siège 15 du support 14. Compte tenu de leur inclinaison, la rainure 16 et la demi-collerette 17 assurent le maintien de la partie de tubulure 5 dans le siège semi-cylindrique 15. En effet, toute traction exercée sur cette partie de tubulure 12 consécutivement à la rotation du mobile 6 dans le sens de la flèche F se traduit, grâce à l'inclinaison de la rainure 16 et de la demi-collerette 17, par une composante de force s'exerçant sur la partie de tubulure 12, dirigée perpendiculairement à son axe longitudinal et vers le support 14 provoquant l'auto-blocage de cette tubulure. Ainsi, la partie de tubulure 12 ne risque pas de sortir accidentellement de son siège 15, de sorte que l'ouverture latérale qui permet d'accéder à ce siège semi-cylindrique 15 peut avoir une largeur égale au diamétre de la section cylindrique du siège 15, la tubulure étant retenue par la composante de force susmentionnée.As can be seen in FIGS. 1 and 2, the half-flange 17 engages in the groove 16 when the tubing part 5 is placed in the seat 15 of the support 14. Given their inclination, the groove 16 and the half-collar 17 maintain the part of tubing 5 in the semi-cylindrical seat 15. In fact, any traction exerted on this part of tubing 12 following the rotation of the mobile 6 in the direction of arrow F is reflected, by virtue of the inclination of the groove 16 and of the half-flange 17, by a force component acting on the tubing part 12, directed perpendicular to its longitudinal axis and towards the support 14 causing the self-locking of this tubing. Thus, the tubing part 12 does not risk accidentally coming out of its seat 15, so that the lateral opening which gives access to this semi-cylindrical seat 15 can have a width equal to the diameter of the cylindrical section of the seat 15, the tubing being retained by the aforementioned force component.

On a déjà indiqué précédemment qu'un autre rôle de la demi-collerette inclinée 17 est d'empêcher l'inversion de la tubulure. En effet, on constate que le dispositif d'assemblage décrit empêche toute inversion de la tubulure. Ceci est valable aussi bien en ce qui concerne l'inversion des parties de la tubulure 1, situées à droite et à gauche du support 14, que celle de la position des conduits 2 et 3 aboutissant au branchement du Y 4, au cas où un tel branchement existe. Il est évident que l'invention est également valable lorsqu'un tel branchement 4 n'existe pas et que la tubulure ne comporte qu'un seul conduit 5 en amont du support 14. Il est également évident que la demi-collerette 17 pourrait par exemple être remplacée par un simple ergot oblique engagé dans un perçage correspondant ménagé à la place de la rainure 16.It has already been indicated previously that another role of the inclined half-collar 17 is to prevent the reversal of the tubing. Indeed, it is found that the assembly device described prevents any inversion of the tubing. This is valid both with regard to the inversion of the parts of the tubing 1, situated to the right and to the left of the support 14, as well as that of the position of the conduits 2 and 3 leading to the connection of the Y 4, in case a such a connection exists. It is obvious that the invention is also valid when such a connection 4 does not exist and that the tubing comprises only one conduit 5 upstream of the support 14. It is also obvious that the half-collar 17 could by example be replaced by a simple oblique lug engaged in a corresponding hole made in place of the groove 16.
