Abstract

A method for processing or "inerting" waste from certain medical sources which may contain hazardous germs. An apparatus is provided on-site for storing the waste as soon as it is produced, completely biologically inerting the waste mass by melting it, compacting the waste and conditioning it in an expendable container. The apparatus essentially consists of a vessel (1) into which the waste is fed via a lock (9), a container (4) secured to the bottom of the vessel, a cover (2) for sealing the space therein, a heater (5) for heating the whole assembly, and complementary devices (10-15) for monitoring the atmosphere in said space and processing the gaseous effluents generated during the inerting process.

Description

Les déchets concernés - le principe de l'inertage
L'objet de la présente invention est un appareillage destiné au traitement des déchets issus de certaines professions de santé, et des laboratoires d'analyses biomédicale.The waste concerned - the principle of inerting
The object of the present invention is an apparatus for the treatment of waste from certain health professions, and biomedical analysis laboratories.

Ces déchets sont généralement constitués par des ustensiles consommables tels que des seringues, aiguilles, vacutainers, coupelles, tubes à essais, etc. This waste is generally constituted by consumable utensils such as syringes, needles, vacutainers, cups, test tubes, etc.

A ces déchets peuvent être associés des cotons ou compresses ayant servis lors des prélèvements ou manipulations. Cotton waste or compresses used during sampling or handling can be associated with this waste.

Certains d'entre eux peuvent contenir des substances biologiques ou autres utilisées lors des opérations de prélèvement et d'analyse: sang, cultures biologiques, alcools ou solvants. Some of them may contain biological or other substances used during sampling and analysis operations: blood, biological cultures, alcohols or solvents.

Cette masse de déchets, produite au long de la journée d'activité, est susceptible d'être contaminée par des bacilles ou virus redoutables, par exemple: hépatite B, SIDA etc. This mass of waste, produced throughout the day of activity, is likely to be contaminated by formidable bacilli or viruses, for example: hepatitis B, AIDS etc.

Le danger d'une contamination reste latent tout au long de la manipulation de ces déchets, jusqu'à l'instant de leur destruction. The danger of contamination remains latent throughout the handling of this waste, until the moment of its destruction.

L'appareil, objet de la présente invention, est destiné à pallier ces dangers en assurant la double fonction de : stockage du déchet "in situ", en sécurité, puis neutralisation complète des dangers par destruction totale de tous germes susceptibles d'habiter ces déchets. The device, object of the present invention, is intended to alleviate these dangers by ensuring the double function of: storage of the waste "in situ", in safety, then complete neutralization of the dangers by total destruction of all germs likely to inhabit these waste.

Sitôt produits, les déchets sont introduits dans l'appareil, dans un réceptacle qui est le lieu même de leur traitement, ce qui évite toutes manipulations pendant le laps de temps où les germes peuvent être actifs. As soon as produced, the waste is introduced into the device, in a receptacle which is the very place of its treatment, which avoids any manipulation during the period of time when the germs can be active.

Lorsque la charge journalière de déchets est complète, le processus de traitement est initié, et son déroulement s'effectue de façon totalement automatique; pendant la nuit par exemple. When the daily load of waste is complete, the treatment process is initiated, and its progress takes place completely automatically; overnight, for example.

Un second pôle d'intérêt réside dans le fait que le traitement à "haute" température de ce type de déchet a pour effet secondaire de produire un compactage important réduisant le volume dans un rapport d'environ 8 à 1 pour les mélanges de déchets considérés plus haut. A second pole of interest lies in the fact that the "high" temperature treatment of this type of waste has the secondary effect of producing a significant compaction reducing the volume in a ratio of about 8 to 1 for the mixtures of waste considered. upper.

Le terme d' "inerteur" a été dévolu à cet appareil en ce sens qu'il transforme une masse de déchets sensibles, comportant des substances diverses, en un bloc dense et complètement stérile. The term "inerter" has been assigned to this device in the sense that it transforms a mass of sensitive waste, comprising various substances, into a dense and completely sterile block.

Au cours du traitement le déchet est conditionné dans un conteneur prévu à cet effet, et devient un déchet industriel, ordinaire, susceptible d'être manipulé sans le moindre danger, qui sera éliminé suivant les processus traditionnels. During the treatment, the waste is packaged in a container provided for this purpose, and becomes an ordinary industrial waste, capable of being handled without any danger, which will be eliminated according to traditional processes.

La double fonction d'inertage biologique et de compactage est réalisée par une cuisson, en vase clos, à un niveau de température de l'ordre de 230 à 240 "C.  The dual function of biological inerting and compaction is achieved by cooking, in a closed vessel, at a temperature level of the order of 230 to 240 "C.

Les déchets des professions médicales susceptible d'être traités par cet appareil sont composés en majeure partie de matériaux dits "plastiques": polyéthylènes, polypropylènes, polystyrènes, etc. , lesquels sont liquéfiés à une telle température
Cette température est maintenue pendant un temps suffisamment long pour intéresser la totalité de la charge de déchets. Sachant qu'aucun germes connu ne résiste à une température supérieure à 125"C, et ce pendant un temps court, I'inertage biologique est donc totalement assuré. The waste of the medical professions likely to be treated by this device is mainly composed of so-called "plastic" materials: polyethylenes, polypropylenes, polystyrenes, etc. , which are liquefied at such a temperature
This temperature is maintained for a time long enough to cover the entire waste load. Knowing that no known germ can withstand a temperature above 125 "C, and this for a short time, biological inerting is therefore completely ensured.

Pendant cette phase de cuisson les effluents gazeux émis par la montée en température des déchets sont traités par des dispositifs traditionnels assurant : la filtration, la neutralisation bactériologique et la désodorisation. During this cooking phase, the gaseous effluents emitted by the rise in temperature of the waste are treated by traditional devices ensuring: filtration, bacteriological neutralization and deodorization.

Une disposition particulière à cet appareil permet par le moyen d'une pompe de mettre la cuve de traitement sous un vide partiel. Ce vide a pour effet de faire gonfler les bulles de gaz incuses dans la masse de déchets en fusion, et, par là, de favoriser leur montée vers la surface. Un cyclage répété de mise sous vide, puis de retour à la pression atmosphérique, permet à la masse visqueuse de déchets liquéfiés d'entraîner les éléments non fusibles, tels que, par exemple :les aiguilles restées sur les seringues, les tubes en verre des "vacutainers de prélèvement, les cotons et compresses. Ces éléments sont noyés dans la masse qui se rassemble dans le conteneur réceptacle. A particular arrangement for this device allows by means of a pump to put the treatment tank under a partial vacuum. This vacuum has the effect of causing the bubbles of incused gases to swell in the mass of molten waste, and thereby favor their rise to the surface. A repeated cycling of evacuation, then of return to atmospheric pressure, allows the viscous mass of liquefied waste to entrain non-fusible elements, such as, for example: the needles remained on the syringes, the glass tubes of the "collection vacutainers, cottons and compresses. These elements are embedded in the mass that collects in the receptacle container.

Les corps creux non fusibles sont remplis par les matériaux plastiques liquéfiés. The non-fusible hollow bodies are filled with liquefied plastic materials.

- Lors du process d'inertage cette cuve est fermée, de façon étanche, par un couvercle (2) qui est verrouillé. - During the inerting process, this tank is closed, in a leaktight manner, by a cover (2) which is locked.

- Sous la cuve vient se positionner le porte conteneur (3) contenant un conteneur consommable (4). Un système de joint permet d'assurer l'étanchéité entre ce conteneur et la cuve, grâce à un dispositif (6) réalisant le placage avec la force nécessaire. - Under the tank is positioned the container holder (3) containing a consumable container (4). A seal system makes it possible to seal between this container and the tank, thanks to a device (6) performing the plating with the necessary force.

- La cuve et le porte conteneur sont munis d'eléments chauffants (5) et de sondes de température permettant le contrôle de celle pendant le process d'inertage. - The tank and the container holder are provided with heating elements (5) and temperature probes allowing the control of that during the inerting process.

- Les effluents gazeux émis pendant le process sont aspirés par la pompe (11), à travers le filtre dessiccateur (10). - The gaseous effluents emitted during the process are sucked up by the pump (11), through the desiccant filter (10).

- Une chambre de traitement (13) assure une filtration complémentaire de ces effluents auxquels une dilution d'ozone produit en (12) vient parfaire neutralisation bio chimique et désodorisation.  - A treatment chamber (13) provides additional filtration of these effluents to which a dilution of ozone produced in (12) completes bio-chemical neutralization and deodorization.

Cet appareil est complètement automatisé dans son fonctionnement, car par nature de son utilisation il sert de réceptacle accessible en permanence pendant la journée de travail (stockage des déchets dès leur production), et le process de traitement est conduit pendant la période d'inactivité (pendant la nuit essentiellement), sans surveillance. This device is fully automated in its operation, because by nature of its use it serves as a receptacle permanently accessible during the working day (storage of waste as soon as it is produced), and the treatment process is carried out during the period of inactivity ( essentially overnight), unattended.
