ABSTRACT:
FIELD OF THE INVENTION
The present invention concerns a multi-stage pad system for the sterile administration of combined moist/dry pads.
BACKGROUND OF THE INVENTION
For certain skin disorders, such as in the case of the care of wounds, but also for cosmetic applications, combined moist and dry stage systems are required. In the case of such systems, on the one hand, a moist compress or bottom pad is present, the purpose of which consists of making direct contact with the skin and, on the other hand, a further dry compress or top pad is provided which is used in such a way that it covers over the moist pad already applied to the skin. Such multi-stage or, more precisely speaking, two-stage systems make high demands on their particular packaging: on the one hand, the sterility of the pads, above all in the medical area of application, must be ensured and, moreover, the part of the pad present in the moist form must not dry out before it is used.
For this problem, according to the present state of the art, administration forms are available which store the moist part in a leak-proof foil, for example aluminium-coated paper, sealed at the edges, such as is the case with the ointment compresses from the company of Medikom GmbH. The dry part of the pad can be stored in a paper sleeve suitable for sterile packaging and also sealed at the edge. Such systems are available on the market, for example from the company of Beiersdorf AG, Hamburg under the registered trademark of Cutisoft. If, on the basis of this state of the art, one wishes to apply a two-stage compress, one must first of all open the package with the moist pad, remove the compress and apply it to the skin area in question. Thereupon the package with the dry component must be opened, after which the latter is removed and is applied over the moist compress already applied. After this, the whole pad can then be fixed in place by, for example, sticking plaster. This way of proceeding according to the state of the art is quite laborious as the user of the pads must always use two different systems individually packaged in each case. It must be ensured that both systems are available in the correct sizes, matching each other, and are also used in the correct order. Moreover, in this way unnecessarily high packaging expenditure is incurred.
SUMMARY OF THE INVENTION
Therefore, it is the task of the present invention to state a multi-stage pad system with packaging which makes easier and less complicated handling possible for the user and at the same time permits a lower expenditure on packaging as compared with the state of the art.
This problem is solved by means of a multi-stage pad system which is, according to the invention, characterised by the fact that a first layer forming an outer wall of the packaging, a second layer forming a separating layer in the packaging, and a third layer forming a further outer wall of the packaging are provided, between the first and the second layers a moist pad, and between the second and third layers a dry pad being located, and all of the layers immediately adjacent to each other in each case showing a common area connected, preferably sealed to each other, and that, moreover, the inner space enveloped by the first and third layers is made in such a way that it is air-tight and moisture-tight. In that way sterility is maintained.
The dry pad as well as the moist pad can be made of lattice tulle or of non-woven gauze. The dry pad is designated a dry mull compress or more simply a dry compress and the moist pad is designated a moist compress, both together are, in their medical application, also designated a wound compress or wound pad.
Due to the double package in accordance with the invention the user has, on the one hand, the necessary pads for treatment and, on the other hand, he does not have to bother about the matching sizes of the pads.
Preferably the dry pad will be larger or at least as large as the moist pad is selected. In this way it is then ensured that the dry pad is always able to completely cover the moist pad and it is thus ensured that fixing means possibly additionally used, mainly sticking plasters, do not come into contact with the moist pad.
A preferred version of the present invention is characterised by the fact that the moist pad is provided with a medical active ingredient, preferably an ointment.
In this case as an active ingredient echipanthenol, for example, can be used in a concentration of 2-4 g/cm
2
, preferably of 2.8 g/cm
2.
A further preferred embodiment of the present invention is characterised by the fact that for the achievement of adequate air-tightness and moisture-tightness the insides of at least one layer, e.g. of the first and second layers, are coated with plastic. Preferably, however, for this purpose an aluminium coating can also be used. Moreover, all of the other coatings or devices which are capable of producing the necessary tightness are, of course, conceivable.
The moist pad itself can, in addition to the layers of the package which envelop it, also be covered with a further piece of protective material, e.g. with a sheet of foil, both on the one side and on the other side. This helps to avoid smearing on the insides of the layers enveloping it. For this purpose, preferably pieces of material of parchment or plastic sheeting are to be provided.
A further preferred embodiment is, according to the invention, characterised by the fact that the multi-stage pad system with packaging shows at least one tearing-open or pulling device, preferably a tongue or a notch on the edge which makes it possible to open the sterile package and to separate the individual layers from one another by means of the pulling device and thus to open the inner spaces formed by these with the respective pads. In this case this notch can, for example, be at the edges (if such are present) or left running all round. This makes it quite considerably easier to tear open the package and thus to open the inner spaces with the pads in them. In the case of a notch at the corners, pulling-open is particularly easy as a result of the fact that such a device leads to diagonal complete pulling-off which is easy for the user. An opening method simple to handle makes it possible for the user to place the particular pad, while maintaining its sterility, i.e. without touching the package with the hands, on the particular part of the body, mostly a wound. Then the remainder of the package opened in this way can be withdrawn from the particular pad (both the moist one and the dry one) again.
In a particularly preferred embodiment, the present invention is characterised by the fact that the multi-stage pad system with packaging shows at least one pulling device, preferably a tongue or a notch at the edge which initially permits only the separation of the first from the second layer by means of the pulling device and thus the opening of the inner space formed by the former with the moist pad. In this case, only after the separation of the first from the second layer does at least one and preferably only one further pulling device become accessible which only then permits separation of the second from the third layer by means of the further pulling device and thus permits opening of the inner space formed by the former, with the dry pad in it. This embodiment thus imposes on the user a defined, medically appropriate order of opening of the different inner spaces. First of all, he must use the moist pad and only then the dry one, which is likewise expedient for sterility which, in the event of opening in the wrong order, is regularly endangered by the ensuing handling problems automatically occurring. A device provided in this way is, as experience shows, far better than a written notice on the package which, due either to negligence or to ignorance of the language, is only seldom read.
After application of the moist pad and of the dry pad an adequately large sticking plaster and/or some longer strips of plaster are sufficient to fix the top pad in place on the skin.
