Definitions
- the invention relates to a method of packing surgical instruments, biological waste and similar infected materials.
- hospital waste i.e. infected waste such as surgical instruments, cannulae, syringes, cults etc. plus gauze gloves, meshes, bandages and biological waste such as organs, experimental animals and blood, are these days effected in compliance with some statutory requirements as laid down by the authorities.
- the waste may be cast in gypsum before it is destructed in the incinerator, but this method is most difficult, as it presupposes mulling of a gypsum dry sand with a relatively short hardening time. To this must be added the weight of such a deposit container full of gypsum and the significant quantity of ashes and waste products deriving from the destruction.
- the object of the invention is to remedy these deficien ⁇ cies and inconveniences of the well-known methods, and this is achieved by a method in which the material is enclosed with synthetic foam in a container, after which the container with the material and the foam may jointly be destructed by incineration.
- the objects packed may be disposed of by incineration, producing no further noxious products from the burning except than a small amount of C0 2 , in which the foam is lyurethan foam.
- the objects 2 will be placed in an empty container 1, which may for instance be a plastic container with a screw cap.
- a mixture of liquid diphenylmethandiisocyanat or a similar product and polyol will be added as a means of foaming.
- the mixture will immediately after the application start foaming and will during the foaming enclose and deposit the objects 2 in such a way that they are kept clear of the wall of the container. Consequently, the objects 2 will during the foaming be raised from the bottom and subsequently be moved towards the centre of the container during the rising of the foam in the container.
- the deposit container filled with foam may hereafter be transported ⁇ to the incinerator in the usual way, after which the container and its total contents will be converted into harmless refuse disposal products.
- a box-shaped wrapping of stainless steel sheets or the like may be applied, which is hinged together along the wall in such a way that the wrapping may be opened and closed.
- a bag or an inner container may then be placed, in which the waste may be deposited. Then the foam producing mixture may be poured over the waste, after which the foaming is effected in the bag or the container in the way generally known. After the hardening the wrapping may be separated, and the block of foam is removed for further handling and destruction.
- the wrapping may be re-equipped with a bag or an inner container and serve as a waste container until foaming has been effect ⁇ ed.
- sheets of synthetic foam may be placed in the bottom and walls of the wrapping, after which the waste may be placed and a lid mounted.
- the foaming has been concluded the waste and the sheets will be kept together in order to form a solid block, which may be removed from the wrapping and reforwarded for either depositing or destruction.
