Description

[0015] Other advantages, as well as the features and use modes of the present invention will result evident from the following detailed description of some preferred embodiments, shown by way of example and not for limitative purpose, by referring to the figures of the enclosed drawings, wherein:

[0016] FIG. 1 is an overall view of the bag according to a preferred embodiment of the present invention.

[0017] FIG. 2 is an overall view of the same embodiment of FIG. 1 wherein some elements of the bag are shown separated and not directly connected to the bag itself.

[0018] The present invention will be described in details hereinafter by referring to the above-mentioned figures.

[0019] By firstly referring to FIG. 1, this represents an overall view showing, as a whole, a bag 1 according to the present invention, according to a preferred embodiment.

[0020] The bag of the present invention is a bag suitable to include liquid organic waste, such as for example urines, thoracic, abdominal drainages, ascites, plasma blood.

[0021] The bag includes inside thereof a first powder 2 capable of releasing the chlorine dioxide biocide into the liquid organic waste when the bag is filled up.

[0022] Advantageously two substances will be used which, once mixed in solution, release chlorine dioxide, the two substances are sodium chlorite and sodium bisulphate.

[0023] This powder bi-component is available under the trade name of TwinOxide.

[0024] The bag 1 advantageously could comprise a second powder 3 apt to absorb the liquid organic waste. Examples of powders suitable to absorb the liquid included in the bag are super absorbent powders with absorption capacity comprised between 60 and 500 times the weight of liquids, such as for example the cross-linked sodium polyacrylate, preferably equipped with system aromatizer, for example the one available under the tradename of Sgaiel. Such powders are able to transform the organic liquid, in particular the urine into gel. Under equipped with system aromatizer it is meant that the substance absorbent itself can be perfumed or mixed to an additional perfumed substance.

[0025] Surprisingly it has been observed that the time for solidifying/gelatinizing the liquid included in the bag, in particular urine, is sufficient to make that chlorine dioxide determines the biocidal action thereof.

[0026] The above-described powders will be included in sacks, preferably water-soluble sacks which when come in contact with the liquid included in the bag dissolve, thus by letting that the powders come into solution. In an alternative embodiment means for breaking the sack could be provided, constituted by a bar. The bar could be made of any suitable material and shape so that the bar can be broken off into one or more portions by an operator. Once broken-off, the bar should produce a cutting surface able to break the sack, but not the outer bag 1.

[0027] The bag of the present invention, for example, could be a disposable bag made of polyethylene, biodegradable polyethylene or pvc and it could be both a primary and a secondary bag.

[0028] In the present description, under the term primary bag any bag is meant suitable to include liquid organic waste, in particular urine, connected or connectable to a catheter 8 and comprising means 9 for emptying the primary bag, for example standard connectors known to the person skilled in the art currently used for emptying this type of bags.

[0029] In the present description under the term secondary bag any bag is meant suitable to include liquid organic waste, in particular urine, comprising means apt to connect the secondary bag to a primary bag so that when the primary bag is filled up with organic liquid, the organic liquid included in the primary bag can be emptied into the secondary bag. Said means, for example, comprises a universal connector which can be connected to means for emptying the primary bags.

[0030] According to an embodiment the bag 1 further comprises means 6,7 apt to separate reversibly a first portion 4 from a second portion 5 of the bag. According to this embodiment the first portion 4 is filled up with liquid, such as urine or others, without coming in contact with the first powder 2 and/or second powder 3 which, on the contrary, is included in the second portion 5. Once the operator removes the separation of the two portions, the powders will enter in contact with the liquid by determining the disinfection and solidification/gelification thereof.

[0031] According to a preferred embodiment represented in FIGS. 1 and 2, the separation means comprises a first element 7, preferably flexible and with cylindrical shape, extending along the bag 1 by defining the two portions to be separated and a second element 6 comprising a portion which hooks to the first element 7 so as to separate reversibly the first portion 4 from the second one 5. As it is clear from FIG. 1 when the operator wishes to eliminate the separation between the two portions, he/she will take off the first element, by making that the second element 6 detaches and the two portions are no more separated.

[0032] A subject of the present invention is also a kit comprising one or more bags according to the present invention and at least a primary bag and/or a secondary bag.

[0033] The present invention has been sofar described with reference to some embodiments thereof. It is to be meant that other embodiments belonging to the same inventive core may exist, all within the protective scope of the herebelow reported claims.
