In medical care in particular, there is a great need today for the disposal of single-use infectious devices, such as cannulas and syringes with cannulas, etc. In order to prevent the further proliferation of cannulas and syringes with cannulas, which are highly desirable, for example, among injecting drug users, far-reaching and detailed arrangements have been made for hospital staff to dispose of such supplies. According to current regulations, manual or mechanical disposal of disposable syringes is therefore carried out, in which case the cannulas must be cut with, for example, forceps or the like. Such an approach is, of course, thorough and time-consuming, but above all dangerous, as it often causes skin scars on the medical staff when handling objects, which can lead to serious infections. There are also hygienic disadvantages and dangers when using special mechanical devices for the disposal of 56488, as the equipment must be cleaned at regular intervals, sometimes from a highly infectious substance, after treatment of infectious patients.

It has now proved possible to eliminate the above-mentioned disadvantages by the method according to the invention, which results in such used disposable articles being treated in such a way that they can no longer be used afterwards and, if necessary, can be cleaned of bacteria at the same time as disposal.

The invention is mainly characterized in that the accessories are simply covered with a mixture after use, which when mixed with a water-soaked solvent gives a rigid or tough or sticky mass which cannot be removed from the accessories without rendering them unusable for new use. Thus, a method is achieved which uses disposable equipment and in this way eliminates the accident hazards which occur in the equipment currently in use.

According to a preferred embodiment of the invention, simultaneous cleaning of the single-use infectious articles from bacteria can then be achieved by contacting the infectious articles with the antimicrobial solution for a necessary time before the final coating on the solidifying mixture. All of this can best happen in one and the same container.

The invention is described in more detail below with reference to the example below.

Example:

The disposable container is partially filled with a suitable antimicrobial premix and used infectious articles, such as used syringes, are gradually lowered into this solution without the need to touch the cannulas by hand or remove them from disposable syringes, for example. In the case of syringes, it is best to pull the plunger rod itself completely out of the syringe barrel, after which the syringe parts are lowered into solution. When the container is almost full of such infectious goods - for example, for a day or longer in smaller establishments - gypsum, for example, is added to the solution, which then, after a very short time, gives a rigid gypsum cake into which the injection parts, etc. have been cast. The container, which is best equipped with a lid, can then, with its rigid contents, be transported away in the usual manner with general waste or the like and disposed of as a unit. Goods enclosed in a tank, which are partly bacterially destroyed and partly cast into a rigid mass, do not constitute any so-called "hazardous waste", which, according to the regulations in force, must be transported in a special way. Experiments have shown that it is not possible to break the gypsum cake obtained in order to obtain functional syringes or syringe parts, 3 56488 because the syringes are no longer usable after such treatment. It is best to provide the gypsum powder with a corrosive, most simply e.g. sodium chloride, which causes corrosion damage to the metal parts thus cast, e.g. the cannulas of the syringes, in a very short time. The addition of sodium chloride also accelerates the solidification of the gypsum mixture. Pre-treatment with an antimicrobial solution also eliminates any risk of possible transmission of infection.

The solidifying agent used to practice the invention may, of course, be not only gypsum but also another substance which, together with water or other solvent and antimicrobial components, gives a rigid mass, e.g. cement, plastic, etc. Thus, the solidifying agent may also be wholly or partially gluing properties such as cold glue powder or the like.

Of course, all commercially available substances suitable for these applications can be used as corrosive and antimicrobial agents.

Claims (5)

4 56488 1. A method of disposing of disposable articles, in particular medical supplies, after use, characterized in that the articles are immersed in a mixture which, when mixed with water or another solvent, gives a rigid or tough or sticky mass which cannot be removed from the articles without rendering them unusable. for new use. Method according to Claim 1, characterized in that the mixture contains gypsum, adhesive, cement, plastic or a mixture thereof as the solidifying component. ?. Process according to Claims 1 to 2, characterized in that the mixture contains, in addition to the solidifying component, an etchant and / or a microbicidal agent. A method for the simultaneous bacterial cleaning and disposal of disposable infectious articles according to claim 1, characterized in that the infectious articles are contacted with an antimicrobial solution before, during or after immersion in the solidifying agent. A method according to claim 4, characterized in that the infectious articles are discharged into a collection container containing a microbicidal solution, and that a solidifying component is added to said solution, which may optionally contain a corrosive, in addition to gypsum, cement, adhesive, plastic or the like.
