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

INEF.TEUR DE DECHETS CONTA-MINES CONTA-MINES WASTE INFACTOR
Les déchets concernés - le principe de lf inertageRelevant waste - the principle f inerting
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 object of the present invention is an apparatus for the treatment of waste from certain health professions, and biomedical analysis laboratories.
X es déchets sont généralement constitués par des ustensiles consommables tels que des seringues, aiguilles, vacutainers, coupelles, tubes à essais, etc. A ces déchets peuvent être associés des cotons ou compresses ayant servis lors des prélèvements ou manipulations.X es wastes generally consist of consumable utensils such as syringes, needles, vacutainers, cups, test tubes, etc. 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. 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.Some of them may contain biological or other substances used during sampling and analysis operations: blood, biological cultures, alcohols or solvents. 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 apparatus, 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. 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.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. 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 températureThe 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
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, l' inertage biologique est donc totalement assuré. Pendant cette phase de cuisson les effluents gazeux émis par la montée en température de déchets sont traités par des dispositifs traditionnels assurant : la filtration, la neutralisatio bactériologique et la désodorisation.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. During this cooking phase the gaseous effluents emitted by the rise in temperature of 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 l cuve de traitement sous un vide partiel. Ce vide a pour effet de faire gonfler les bulles d gaz incuses dans la masse de déchets en fusion, et, par là, de favoriser leur montée vers l 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, tel que, par exemple :les aiguilles restées sur les seringues, les tubes en verre des "vacutainer de prélèvement, les cotons et compresses. Ces éléments sont noyés dans la masse qui s rassemble dans le conteneur réceptacle.A special arrangement for this device allows the treatment tank to be placed under a partial vacuum by means of a pump. The effect of this vacuum is to cause the bubbles of incused gases to swell in the mass of molten waste, and thereby encourage 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 vacutainer, cottons and compresses. These elements are embedded in the mass which 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.
