Description

"Apparatus for applying stoma plates"

This invention relates to an apparatus for heating stoma plates quicker and uniformly up and for adhering them onto the skin thanks to pressure. Stoma plates, destined to be adhered in case of colostomy, ileostomy or urostomy at the place of the operation onto the skin, are always provided on one side with an adhesive layer. Usually this adhesive layer is based on pectin showing better adhesive properties upon heating up. To such a stoma plate, which has a central opening, a small bag has to be fixed to collect the faeces or the urine.

Heating up was usually achieved by massaging the material of which the plate is made around the central opening with the finger.

Due to the rubbing action, heat is generated making the pectin layer sticky in so that the small stoma plate may adhere onto the skin after 10 to 20 minutes of this treatment. This time span is not only too long and too time-consuming but the heating action was regularly found to be insufficient.

Attempts are already taken to design an apparatus which was equipped with non-rechargeable batteries. This small apparatus showed several drawbacks, the most important of which was the too low available temperature. Also the necessity to replace the batteries in time, appeared to be a substantial nuisance and made the use of the apparatus too little flexible. In this respect it is important that heat can be generated and that pressure can be exerted onto that part.

An object of the invention is now to provide an apparatus allowing to heat and adhere the part of the stoma plate which is to be heated quickly and with the highest precision.

To solve the problems set forth hereinabove and other problems associated therewith, the apparatus according to the invention comprises a style and an adjustable heating resistance for keeping at least the head of said style at a pre-adjusted temperature.

In a very advantageous embodiment said heating resistance is a self-regulating heating resistance. In a particular embodiment said heating resistance is of the P.T.C.-type, respectively the N.T.C. -type.

Other details and advantages of the invention will become apparent from the following description of an apparatus according to the invention. This description is only given by way of example and does not limit the invention. The reference numerals relate to the figures annexed hereto.

Figure 1 is a longitudinal section through the apparatus according to the invention.

Figure 2 illustrates how to use the apparatus according to the invention.

The apparatus shown by these figures is composed of a style 1, provided with a heatable head 2 with a rubbing surface 3. This rubbing surface has from an ergonomic point of view an arcuate profile. The heatable head 2 consists of a conductive mass having a central cavity 4 wherein a heating resistance 5 is built in. This heating resistance 5 is connected by electrical conductors 6 to a low voltage power point 7. Characterising for the invention is the use of a self-regulating resistance of the P.C.T.-type (Positive Temperature Control) or of the N.T.C.-type (Negative Temperature Control) as heating resistance. Use can also be made of a resistance supplied via a thermostat.

By using a heating resistance of the P.T.C-, respectively the N.T.C.-type the entire apparatus may have very small dimensions and can therefore be constructed very compactly. As a result thereof, the patient has a good control of the apparatus whilst the heated rubbing surface of the style head shows optimal dimensions.

In the three cases the style head is therefore always brought at its ideal temperature and kept at this ideal temperature.

The arcuate rubbing surface 3 of the head 2 of the style 1 is preferably provided with a layer of polytetrafluoroethylene (teflon) increasing the rubbing capacity of the style considerably.

Thanks to this "Teflon"-layer, it is also possible to massage the stoma plate through a bag of polyethylene or of a technically equivalent material.

For a patient (shown in figure 2) it is now possible to bring in a very short time a stoma plate 8, usually the circular central part 8' thereof, at the desired temperature. The heat sensitive pectin layer, which is applied on one side of the stoma plate 8, can be heated up now by the patient without problems and brought to the desired temperature without having to pass on to this end to a regular and sustained rubbing of the central part of the stoma plate.

The temperature generated by the heating resistances of said type is therefore always of the desired level and burns are consequently entirely excluded. A lot of patients have to cope with skin irritations and wounds in the area around the stoma. By using cicatrising and wound healing powders these patients encounter particular difficulties for adhering their stoma plates in this area.

It has been found that the apparatus according to the invention increases the adhesive properties of said plates considerably, also in these difficult circumstances wherein both the use of powders and the presence of liquid seriously hamper adhering the stoma plates.

The style 1 may be hollow but the electrical conductors 6 could also be embedded in a ceramic or insulating filling mass. It is also possible to use a separate holder wherein the style can be applied. The holder would be kept then at an adjustable temperature level which is kept at a constant value.
