Description

[0021] The invention will now be explained in more detail with reference to a drawing in which:

[0022] FIG. 1 is a first view of an embodiment of a stoma dressing holder according to the invention;

[0023] FIG. 2 is a second view of an embodiment of a stoma dressing holder according to the invention;

[0024] FIG. 3 is a detailed view of an embodiment of a stoma dressing holder according to the invention;

[0025] FIG. 4 is another detailed view of an embodiment of a stoma dressing holder according to the invention.

[0026] For a better understanding of the invention, corresponding parts shown in the various figures will be referred to by identical numerals in the description of the figures below.

[0027] In FIG. 1 a first view of an embodiment of a stoma dressing holder according to the invention is shown.

[0028] The holder for the stoma dressing is indicated at 10 and forms an envelope which envelopes or encloses a space 15. The envelope is preferably made up of a first layer of fabric 11 and a second layer of fabric 12, which are joined at their circumferential edges 13. The two layers of fabric 11 and 12 are not joined at one circumferential edge portion, so that the space 15 formed by the two layers of fabric 11 and 12 can be accessed. One of the layers of fabric 11 or 12, in this case layer 12, may be provided with a flap 14 that can be folded over the open circumferential edge portion, so that the space 15 can (more or less) be closed.

[0029] In FIG. 2 another side of the stoma dressing holder according to the invention is shown. The layer of fabric 12 is provided with a further layer of fabric 20 on this side, which layer of fabric 20 is provided on top of the layer of fabric 12, thus forming a further envelope. Said further envelope can preferably be closed using suitable closure means 22, in the form of a zip fastener in FIG. 2. It is also possible, however, to use other closure means 22, for example a press-stud or a magnetic closure, or a Velcro-based closure. Said further additional layer of fabric 20 is provided with a see-through window 21, whose function will be explained hereinafter.

[0030] Although the holder 10 is described herein as an envelope made up of two first and second layers of fabric 11 and 12, respectively, which are joined near their circumferential edges 13, the layers 11 and 12 need not be made of a fabric. The two layers 11 and 12 may also be made of a different kind of material, for example plastic. Furthermore, the layers 11 and 12 may be made of one double-folded strip (of fabric), with one of the joined circumferential edges 13 forming the folded edge.

[0031] The envelope described with reference to FIGS. 1 and 2 is intended to receive a stoma dressing. Stoma dressings are provided with an opening that is to be placed around the stoma wound, and with an adhesive barrier for attachment to the skin directly surrounding the stoma wound. Such stoma dressings are usually intended for single or short use and must be exchanged regularly, therefore. It has been found that when the stoma dressing is exchanged, the clean stoma dressing adheres best to the body if the temperature of the stoma dressing, and in particular of the adhesive barrier around the stoma dressing of the collection cavity, is about the same as the temperature of the patient's skin.

[0032] The holder 10 according to the invention is for that purpose provided with heating means for heating the clean stoma dressing, which is to that end temporarily placed in the space 15 of the envelope holder 10.

[0033] An embodiment of the heating means is shown in FIG. 3 and FIG. 4. The heating means shown therein comprise an electrical heating element 25, which is provided in one (or both) of the layers 11-12 of the envelope holder 10 in the form of an electrical heating wire.

[0034] For the sake of clarity of the invention, numerals 11a-12a indicate the outer side of the layers 11 and 12, respectively, whilst numerals 11b and 12b represent the inner side of the two layers, which inner sides 11b-12b face one another in the space 15. According to the invention, the heating means are provided in the inner layer 11b or 12b of the layers 11 or 12.

[0035] The electrical heating wire 25 is arranged in the form of several envelopes or windings 25′ over the entire inner layer area 11b-12b of the layers 11 and/or 12. As a result, a maximum area of contact between the inner layers 11b and/or 12b and the stoma dressing present in the space 15 is realised, so that an optimum heat transfer from the electrical heating wire 25 to the stoma dressing takes place. This results in a uniform but above all quick heating of the stoma dressing, which can thus be evenly but also quickly heated to about the temperature of the patient's skin. In this way also the adhesive barrier will quickly and homogeneously reach the temperature that corresponds to the temperature of the patient's skin, resulting in a better adhesion of the stoma dressing to the skin surrounding the stoma wound and thus to an adequate, durable and above all moisture-tight connection.

[0036] It should be noted that the space 15 formed by the envelope holder 10 can be closed, preferably by means of a flap 14, as shown in FIG. 1. The holder 10 may or may not be provided with additional closure means, analogously to the closure means 22 that close the further envelope 20. The closure means by which the space 15 of the envelope holder 10 can be closed may consist of a zip fastener or one or more press studs, or of a magnetic closure or, for example, a Velcro closure, in which case Velcro material will be present both on the inner side of the flap 14 and on the portion of the outer side 11a (or 12a) of the layer 11 (or 12) that is brought into contact with the flap 14.

[0037] As shown in FIG. 3, the electrical heating wire 25 is worked into the envelope, and in particular into the inner side 11b-12b of the layer 11 and/or 12, in the form of loops 25′. The electrical heating wire 25 is further provided with terminal ends 25a-25b, to which a power supply (power source) can be connected. The power supply may in particular be a power supply that is capable of being switched on and off; more in particular it may be a rechargeable power supply. In a very functional embodiment, the power supply in question is accommodated in the further envelope 20, in which envelope 20 it is connected to the wire ends 25a and 25b, which to that end project from the layer of fabric 11b or 12b and extend into the further envelope 20 for being suitably connected to the terminals of the power supply. The heating wire 25 may on the other hand be a wire which is configured as a bundle comprising a large number of conducting wires.

[0038] On the other hand, the holder can be connected to a 110V/220V power source.

[0039] The power supply accommodated in the further envelope 20 may be provided with suitable setting means, such as an on-off button that can be operated by being pressed by the user. For this purpose the transparent part 21 of the further envelope 20 is used, behind which the power supply provided with the setting means can be placed, enabling the user (the stoma patient) to suitably switch the power supply on and off through the transparent window.

[0040] In the case of further functionality, the setting means are provided with time setting means, so that the power supply is activated for a certain, preferably preset heating time upon being switched on and is automatically switched off after said heating time has elapsed.

[0041] In another, suitable embodiment the heating time is preset in the setting means, which time setting is of a permanent nature. In another, more functional embodiment, the heating time can be set as desired in dependence on the type of stoma dressing and the varying properties of the associated adhesive barrier. It should be emphasised in this regard, however, that with all the different types of stoma dressings the heating times can be set so that the stoma dressing in question will have been brought to the correct temperature corresponding to the patient's skin temperature once the respective, separately adjusted heating time has lapsed.

[0042] Furthermore, the temperature can be increased in steps during a certain heating time (a fixed heating time or a heating time to be set by the user), for example by adjusting the output of the power supply in steps of 25%-50%-75%-100% of its maximum output.

[0043] In another, more complex embodiment, the setting means are provided with a temperature sensor which measures the heating temperature that prevails in the envelope 15 and automatically switches off the power supply when the desired, maximum heating temperature is reached.

[0044] In all these functional embodiments, the stoma dressing is prevented from being heated too long or to a too high temperature, which may lead to irritation or injury upon application of the stoma dressing to the skin. Nor can the stoma dressing be heated for too short a period of time, as a consequence of which the adhesive barrier would be heated insufficiently for realising an adequate, durable and above all moisture-tight connection to the skin.

[0045] FIG. 4 shows in more detail an embodiment of the way in which the electrical heating wire 25 is worked into a layer 11 or 12 of an envelope holder according to the invention.

[0046] In this embodiment, each layer 11 or 12 is made up of an outer side layer 11a (12a) and an inner side layer 11b (12b), respectively. The inner side layers 11b (12b) form the space 15 in which the stoma dressing is accommodated. Between the outer side layer 11a (12a) and the inner side layer 11b (12b), the heating wire 25 is provided in several loops or windings 25′, whilst the two layers 11a-11b (12a-12b) are joined at the locations indicated by numerals 11c-12c. In this way channel-shaped spaces 11d-12d are formed, in which the electrical heating wire 25 is accommodated. In this embodiment the electrical heating wire 25 is made up of a bundle comprising a large number of conducting wires 250, which may optionally be enveloped in a sheath 25a. Said large number of conductor wires 250 may also be provided in the layers 11 (12) in the form of a bundle (without a sheath 25a).

[0047] It will be understood, however, that also other types of heating wires may be worked into the layers of material 11 or 12.
