Abstract
Description
La présente invention concerne un lit fluidisé perfectionné, permettant une utilisation simplifiée et assurant une hygiène accrue.The present invention relates to an improved fluidized bed, allowing simplified use and ensuring increased hygiene.
Il est connu des lits fluidisés comportant une cuve contenant des microsphères passant à l'état fluide sous l'action d'un fluide gazeux, tel que l'air, sous pression ; cette pression, même faible, permet ce passage à l'état fluide des microsphères, dont les dimensions peuvent aller de 20 µ à 200 µ. En l'absence d'air pulsé, la masse de microsphères se présente sous forme de sable compact.Fluidized beds are known comprising a tank containing microspheres passing into the fluid state under the action of a gaseous fluid, such as air, under pressure; this pressure, even low, allows this passage to the fluid state of the microspheres, the dimensions of which can range from 20 μ to 200 μ. In the absence of forced air, the mass of microspheres is in the form of compact sand.
Ces lits fluidisés ont constitué pour les patients, notamment ceux nécessitant un alitement prolongé ainsi qu'aux grands brulés un progrès certain. Un drap filtrant recouvrant ladite cuve est habituellement utilisé, laissant passer l'air, généralement chaud, permettant la fluidisation des microsphères et évitant que ces dernières n'entrent en contact avec le corps du patient.These fluidized beds have been a definite improvement for patients, especially those requiring prolonged bed rest as well as for burn victims. A filter sheet covering said tank is usually used, letting the air, generally hot, allow the fluidization of the microspheres and preventing them from coming into contact with the patient's body.
A l'inverse, ce drap filtrant laisse passer les exsudats issus du patient qui s'écoulent dans la masse des microsphères, jusqu'à former avec ces dernières des agglomérats présentant l'aspect d'une pierre dont la taille peut varier de celle d'un gravier à celle d'un pavé de rue.Conversely, this filter sheet lets exudates from the patient pass which flow into the mass of microspheres, to form with them agglomerates having the appearance of a stone whose size can vary from that of 'gravel to that of a street paver.
L'accumulation de ces agglomérats provoque :
- une altération de la fluidisation
- une altération de l'aseptie de la charge
- une altération de la régulation de température (la concentration d'agglomérats à proximité de la sonde de régulation provoque en effet un point chaud faussant la mesure de température).
- impaired fluidization
- impaired aseptic charge
- alteration of temperature regulation (the concentration of agglomerates near the regulation probe indeed causes a hot spot distorting the temperature measurement).
Ces problèmes, connus de l'homme du métier ont amené ce dernier à prévoir un tamis métallique disposé dans le fond de ladite cuve et muni de poignées permettant l'extraction de celui-ci avec les agglomérats reposant sur ledit tamis.These problems, known to those skilled in the art, have led the latter to provide a metal sieve placed in the bottom of said tank and provided with handles allowing the extraction thereof with the agglomerates resting on said sieve.
Un tel perfectionnement a permis de filtrer périodiquement la cuve, ce qui était rendu nécessaire par la présence des agglomérats précités qui renferment de nombreux germes néfastes au patient et à l'environnement.Such an improvement made it possible to periodically filter the tank, which was made necessary by the presence of the abovementioned agglomerates which contain numerous harmful germs for the patient and the environment.
Toutefois, un tel tamis reposant sur le fond de la cuve présente un certain nombre d'inconvénients ; pour extraire ledit tamis, il faut en effet que le personnel soignant plonge les bras à l'intérieur de la cuve, ce qui, en dehors des problèmes d'hygiène et de contamination pour ce personnel, occasionne des jets de microsphères sur le sol, le rendant très glissant et pouvant provoquer des chutes graves.However, such a sieve resting on the bottom of the tank has a number of drawbacks; to extract said sieve, it is indeed necessary for the nursing staff to plunge their arms inside the tank, which, apart from the hygiene and contamination problems for this staff, causes jets of microspheres on the floor, making it very slippery and can cause serious falls.
De plus, ce tamis est de surface plus faible que celle de la cuve, d'où la possibilité pour certains agglomérats de se glisser dans l'espace libre situé entre la paroi interne de la cuve et le bord dudit tamis ; il n'est pas rare que cet espace libre ait une largeur de plusieurs centimètres. En conséquence, il conviendra d'effectuer une vidange complète de la cuve au moins une fois par an, ce qui constitue une contrainte supplémentaire pour le personnel soignant.In addition, this sieve has a smaller surface area than that of the tank, hence the possibility for certain agglomerates to slip into the free space situated between the internal wall of the tank and the edge of said sieve; it is not uncommon for this free space to be several centimeters wide. Consequently, a complete emptying of the tank should be carried out at least once a year, which constitutes an additional constraint for the nursing staff.
Enfin, le tamis étant habituellement réalisé en métal nécessite des matériaux nobles, donc coûteux, inoxydables et plus généralement inattaquables par les divers agents chimiques contenus dans les exsudats du patient.Finally, since the sieve is usually made of metal, it requires noble materials, therefore expensive, stainless and more generally unassailable by the various chemical agents contained in the patient's exudates.
La présente invention pallie ces divers inconvénients et aboutit à un dispositif à la fois d'utilisation simplifiée et permettant une hygiène renforcée tant pour le patient que pour le personnel soignant.The present invention overcomes these various drawbacks and results in a device which is both simplified in use and allows improved hygiene both for the patient and for the nursing staff.
De façon plus précise, la présente invention concerne un lit fluidisé du type comportant une cuve contenant des microsphères, la base de ladite cuve étant réalisée en un matériau poreux permettant le passage d'un fluide gazeux sous pression, réalisant ainsi la fluidisation desdites microsphères, le dessus de ladite cuve étant recouvert d'un drap filtrant fixé au pourtour de ladite cuve, caractérisé en ce qu'il comprend une poche disposée à l'intérieur de ladite cuve, ladite poche consistant, en sa partie supérieure, en ledit drap filtrant, le reste de ladite poche étant constituée d'une substance dont une partie au moins forme tamis.More specifically, the present invention relates to a fluidized bed of the type comprising a tank containing microspheres, the base of said tank being made of a porous material allowing the passage of a gaseous fluid under pressure, thus achieving the fluidization of said microspheres, the top of said tank being covered with a filter sheet fixed to the periphery of said tank, characterized in that it comprises a pocket disposed inside said tank, said pocket consisting, in its upper part, in said filter sheet , the rest of said pocket being made of a substance, at least part of which forms a sieve.
Selon une variante d'exécution, ladite poche est exclusivement constituée d'une partie consistant en le drap filtrant et d'une partie réalisée en une substance formant tamis.According to an alternative embodiment, said pocket consists exclusively of a part consisting of the filter sheet and of a part made of a substance forming a screen.
Selon une deuxième variante, ladite substance formant tamis est rigide.According to a second variant, said sieve-forming substance is rigid.
Selon une troisième variante, ladite substance formant tamis est souple, des lests étant alors prévus pour que la poche présente un volume maximal.According to a third variant, said substance forming a sieve is flexible, weights being then provided so that the bag has a maximum volume.
D'autres variantes sont également prévues qui feront l'objet de précisions plus avant dans la présente description complétée par les dessins où :
- la figure 1 représente une coupe longitudinale partielle du lit fluidisé selon un mode de réalisation de l'invention,
- la figure 2 représente une coupe longitudinale partielle du lit fluidisé selon un autre mode de réalisation de l'invention.
- FIG. 1 represents a partial longitudinal section of the fluidized bed according to an embodiment of the invention,
- 2 shows a partial longitudinal section of the fluidized bed according to another embodiment of the invention.
Selon la figure 1, le mode représenté fait apparaître la cuve 1 reposant sur ses pieds 2 ; le fond de la cuve 1 comporte une chambre 3 séparée du reste de la cuve par un diffuseur 4 qui permet le passage de l'air pulsé, chauffé, provenant de la chambre 3. De façon à ne pas charger cette figure, la demanderesse n'a pas représenté les autres éléments des lits fluidisés connus à ce jour, et notamment la ou les prises d'air et filtres, la turbine permettant d'avoir un air sous pression, les moyens de chauffage de l'air et de régulation de la température dudit air.According to Figure 1, the mode shown shows the
Conformément à la présente invention, on notera la présence de la poche constituée du drap filtrant 5 et de la substance 6 formant tamis. Dans ce mode de représentation, la totalité de la substance 6 forme tamis, et ladite substance 6 est souple, nécessitant la présence de lests 7, permettant ainsi à la poche d'avoir un volume maximal, le plus grand nombre des microsphères 8 se situant alors dans ladite poche.In accordance with the present invention, the presence of the bag made up of the
Divers modes de réalisation ne font pas ici l'objet de figures spécifiques ; le tamis peut n'occuper qu'une partie de la substance 6, et/ou cette dernière peut être en matériau rigide, en particulier en matière plastique. Lorsque toute la substance 6 a une fonction de tamis et qu'elle est réalisée en matériau rigide, il n'est pas nécessaire de prévoir des lests comme indiqué ci-dessus.Various embodiments are not the subject of specific figures here; the sieve may occupy only part of the
Ces lests peuvent consister en des masselottes ou des barreaux, réalisés en tout matériau adéquat c'est-à-dire inoxydable, inaltérable, par exemple en métal ou en toute autre matière, enrobé ou non de matière plastique ; de tels lests seront préférentiellement fixés dans la partie inférieure de la poche, éventuellement de façon amovible, à l'intérieur ou à l'extérieur de ladite poche. Si cette dernière prend la forme d'un sac entièrement fermé, et donc jetable avec les agglomérats qui y sont contenus, les lests seront fixés à l'extérieur de ladite poche.These weights may consist of weights or bars, made of any suitable material, that is to say stainless, unalterable, for example of metal or any other material, coated or not with plastic material; such weights are preferably fixed in the lower part of the pocket, optionally removably, inside or outside of said pocket. If the latter takes the form of a fully closed bag, and therefore disposable with the agglomerates contained therein, the weights will be attached to the outside of said pocket.
Dans le mode de réalisation illustré à la figure 1, la poche, constituée des éléments 5 et 6 n'est pas un sac entièrement fermé, mais présente une ouverture que l'on peut fermer avec du velcro 9, ou tout autre moyen de fermeture ; cette ouverture, s'étendant sur tout ou partie du pourtour de la poche, permet, après extraction de la poche hors de la cuve, de retirer les agglomérats contenus dans ladite poche avant de nettoyer les éléments 5 et 6 destinés à être réutilisés ultérieurement. Dans ce type d'ouverture munie de velcro, on notera que le drap filtrant 5 dépasse de la substance 6, constituant ainsi une bande destinée à être fixée par tout moyen connu 10 sur le pourtour de la cuve. Il est important en effet dans ce mode de réalisation que l'ouverture munie de velcro 9 se situe à l'intérieur de la cuve 1 : de cette façon, les microsphères 8 susceptibles de passer à travers le velcro 9 en raison de leur petite taille resteront dans la dite cuve, la bande précitée évitant auxdites microsphères de s'échapper de la cuve et de se répandre sur le sol.In the embodiment illustrated in Figure 1, the pocket, consisting of
Le mode de réalisation illustré à la figure 2 reprend les mêmes éléments 1 à 8 que ceux de la figure 1 ; la différence se situe au niveau de l'ouverture de la poche et de son mode de fermeture et de fixation au pourtour de la cuve 1 ; dans cette figure 2, on remarque que cette fermeture et cette fixation se font à l'aide d'un profilé 11, solidaire de la cuve, et dont une partie vient pincer les bords des éléments 5 et 6 empêchant ainsi que des microsphères 8 ne s'échappent, tout en permettant l'évacuation d'aggrégats lorsque la poche est extraite de la cuve.The embodiment illustrated in Figure 2 includes the
Quel que soit le mode de réalisation représenté dans les figures 1 et 2 où la fonction de tamis est réalisée par l'ensemble de la substance souple 6, on utilisera avantageusement une toile à tamis dont la taille des mailles sera choisie en fonction de la dimension minimale des aggrégats que l'on veut récupérer ; à titre indicatif, des mailles de quelques millimètres, 3 - 5 par exemple, donnent des résultats tout-à-fait satisfaisants.Whatever the embodiment shown in Figures 1 and 2 where the sieve function is performed by all of the
Les perfectionnements apportés par la présente invention pallient les inconvénients cités dans l'art antérieur et apportent un confort et une hygiène accrus tant pour le personnel soignant que pour le patient.The improvements brought by the present invention overcome the drawbacks mentioned in the prior art and provide increased comfort and hygiene for both the nursing staff and the patient.
Le personnel soignant n'a plus à plonger les bras pour aller récupérer le tamis situé au fond de la cuve ; il lui suffit de saisir et de soulever la poche, ce qui provoque un resserrement de cette dernière, limitant ainsi les jets de microsphères sur le sol, dans les yeux et sur les vêtements du personnel soignant. Ce dernier n'a par ailleurs plus besoin de se pencher au dessus de la cuve, et n'a donc plus à inhaler les émanations dues aux flux d'air pulsé. L'hygiène ambiante de la chambre du patient s'en ressent également.Nursing staff no longer have to dive in to recover the sieve located at the bottom of the tank; he just has to grab and lift the pocket, which causes the pocket to tighten, thus limiting the jets of microspheres on the ground, in the eyes and on the clothes of the nursing staff. The latter also no longer needs to bend over the tank, and therefore no longer has to inhale the fumes due to the flow of forced air. The ambient hygiene of the patient's room is also affected.
L'opération de tamisage étant réduite et simplifiée, il y a moins de risques que le personnel soignant n'apporte des germes extérieurs, ce qui, dans les services de brulés, greffe de moelle, déficience du système immunitaire, est un point majeur. Cette facilité de manipulation permet d'intervenir chaque fois qu'il y a au niveau du patient un écoulement important, hémorragie par exemple ; dans ce cas en effet, les agglomérats ainsi formés ont tendance à stagner, mettant longtemps à être neutralisés par déshydratation. Là encore l'hygiène du patient est améliorée, le changement de poche se faisant très rapidement et sans difficulté.The sieving operation being reduced and simplified, there is less risk that the nursing staff does not bring in external germs, which, in burns departments, bone marrow transplants, impaired immune system, is a major point. This ease of handling makes it possible to intervene each time there is a significant discharge from the patient, hemorrhage for example; in this case, in fact, the agglomerates thus formed tend to stagnate, taking a long time to be neutralized by dehydration. Again the patient's hygiene is improved, the change of pocket being done very quickly and without difficulty.
La poche une fois retirée avec ses agglomérats pourra facilement être vidée dans un endroit adéquat, puis nettoyée avant d'être réutilisée.The bag once removed with its agglomerates can easily be emptied in a suitable place, then cleaned before being reused.
