Description
Field of the Invention
The present invention refers to a nasal splint system comprising a nasal splint with a central part designed to rest on the bridge of the nose and two lateral parts designed to rest on each side on the cheek adjacent the nose, wherein the nasal splint is adaptable to the individual form of the nose of a patient and can be fixed, if necessary, additionally with a forehead support consisting of a transversal part designed to rest on the forehead and a central part designed to rest on the nasal splint.
Background of the Invention
Until now splints formed from plaster, thermoplastic synthetics or light metal are known. Plaster on the nose is ugly and additionally soils both patient and surgeon during application. In spite of the fact that the quality of the thermoplastic synthetics has been improved, their use for nasal splints remains troublesome because for corrections the splint has to be warmed and then re-cooled. Moreover the presently available light metal and synthetic splints often do not reach the processus frontalis maxillae and therefore rest only on the bridge of the nose being itself mobile.
The nasal splint described in the U.S. Pat. No. 4,340,040 can be considered as prior art. It reveals a post-operative nasal splint consisting of a central part and two lateral parts composed of a flexible metal layer covered by a foam rubber layer. The flexibility allows the splint to be individually fitted. However it is not possible to consider this known splint as composed of layers of compound materials. Furthermore this known construction comprises several protruding parts which may cause further wounds or injuries when the patient hits a pillow when turning the head. In this case the impact energy will be transmitted directly to the bridge of the nose, which should be protected. Moreover the sling for placing a pad under the patient's nose is complicated and not easy to handle.
Summary of the Invention
The task of the present invention is to create a nasal splint system providing a optimal support of the mobile bridge of the nose, wherein the nasal splint should not only cover the bridge as usual but also a facultative osteotomy gap in the processus frontalis maxillae when choosing the respective size. If necessary, an additional fixation by a forehead support should also be possible.
For solving this task according to the invention there is proposed a nasal splint system comprising a nasal splint with a central part designed to rest on the bridge of the nose and two lateral parts designed to rest on each side on the cheek adjacent the nose, wherein the nasal splint is adaptable to the individual form of the nose of a patient and can be fixed, if necessary, additionally with a forehead support consisting of a transversal part designed to rest on the forehead and a central part designed to rest on the nasal splint, wherein the nasal splint and/or the forehead support is formed of a compound structure consisting of an intermediate flexible layer, of a foam rubber layer adjacent the nose being covered by a skin-compatible adhesive layer and of a layer covering the adhesive layer.
The invention equally facilitates the plastic surgeon's task as well as saving him time, because it offers a nasal splint system providing a stable fixation with the support of the processus frontalis maxillae together with the three point fixation, either with adhesive tapes alone or, if necessary, with the additional stabilization of the forehead support. Furthermore the inventive compound structure allows an easy adaptation to the individual form of the nose of the patient. The inventive nasal splint system allows to protect the nose without any restrictions and minimizes any potential risks of injuries because there do not exist any protruding parts when the nasal splint is fixed.
The flexible layer may be composed of aluminium or other light-weight materials, which can be used in sterile environments during surgery. For providing protection of the flexible layer and also for allowing a better handling of the inventive nasal splint system, there is further proposed according to a preferred embodiment that the flexible layer is covered with a surface layer. Furthermore preferably the layer covering the adhesive layer is made of silicone paper.
For allowing a sufficient support of the mobile bridge of the nose and effectively preventing pain resulting from excessive pressure at particular positions of the nose there is preferably proposed that the thickness of the foam rubber layer is between 0.5 and 2 mm, in particular about 1 mm.
According to a further preferred embodiment the adhesive layer covers only parts of the nasal splint and/or the forehead support.
For an easy manufacture it is preferably proposed that the lateral parts of the nasal splint are formed as integral parts with the central part designed to rest on the bridge and wherein the distance of the two ends of the central part in a direction perpendicular to the orientation of the lateral parts is at least double the extension of the lateral parts in the same direction. The inventive dimensions of the central and lateral parts of the nasal splint furthermore allow a sufficient support in the central area and an easy adaptation on the cheeks adjacent the nose.
Since human noses rarely show straight outer contours of the nose the central part of the nasal splint is provided with at least one slit running in a direction parallel to the orientation of the lateral parts of the nasal splint according to a further preferred embodiment. Such slit allows an easier bending of the central part of the nasal splint when fitting it to the nose of a patient and further considering the fact that below the nasal splint there might be arranged bandages for covering wounds.
As already stated above an additional fixation by a forehead support may be necessary in certain cases. Therefore it is preferably proposed that the central part of the forehead support is provided with a further transversal part at the end being opposite of the transversal part designed to rest on the forehead, and wherein the further transversal part of the forehead support measures about 50% to 80%, in particular 60% to 75%, of the width of the central part of the nasal splint. Thereby the further transversal parts of the forehead support allows a good fixation on the central part of the nasal splint.
For providing the inventive nasal splint system in standard sizes it is further proposed that the distance between the central lines of the transversal parts of the forehead support is between 2.5 and 4.5 cm, in particular about 3 to 3.5 cm.
