Description
Pansement
La présente invention a pour objet un pansement pouvant tre appliqué sur des surfaces du corps humides et qui reste collé à ces surfaces pendant de longues durées.
Jusqu'ici, les dentistes, les chirurgiens-dentistes, les dermatologues et d'autres praticiens de l'art médical ne disposaient pas de pansement pouvant tre employé localement sur des surfaces du corps, internes et externes, mouillées ou sèches, pendant de longues durées. En particulier, les tentatives d'utiliser des bandes spéciales ou des pansements analogues sur des surfaces mouillées du corps ont toujours échoué. L'humidité rencontrée au moment de l'application empche l'adhérence de la bande. Les tentatives de surmonter cette difficulté au moyen d'onguents ou d'autres substances semblables ont également échoué, en raison du fait que l'humidité présente élimine rapidement par lavage les onguents et les substances semblables.
I1 a maintenant été trouvé possible de préparer un nouveau pansement qui adhère instantanément aux surfaces du corps, et de préférence aux surfaces humides du corps, et tout particulièrement aux surfaces humides internes de la cavité buccale. Ce nouveau pansement est doux, flexible, facile à appliquer et, une fois appliqué, il se conforme à la courbure de la surface sur laquelle il repose, spécialement dans le cas de l'application sur la surface de la cavité buccale. Le pansement selon l'invention n'a ni odeur ni goût et, après avoir été appliqué sur la surface à traiter, il ne s'exfolie pas de lui-mme, mais s'use lentement au cours d'un laps de temps prolongé. Ce nouveau pansement reste en place et supporte toutes les activités de la personne traitée.
Par exemple, la personne peut boire, manger, dormir, parler, mâcher ou mordre sans aucun signe d'irritation ou de toxicité.
I1 a été découvert qu'un nouveau pansement convenant tout particulièrement pour l'application sur des surfaces du corps humides, par exemple sur des surfaces intrabuccales, peut tre préparé à partir de certaines matière connues qui n'avaient encore jamais été employées pour ce but. Essentiellement, le pansement selon l'invention est basé sur l'emploi de composition ou pellicules adhésives remarquables.
Les compositions ou pellicules adhésives pouvant tre employées pour la mise en oeuvre de l'invention sont celles qui, seules ou en combinaison avec d'autres compositions analogues, se sont avérées adhérer à des surfaces du corps. Les compositions et pellicules adhésives de l'invention comprennent un ou plusieurs hydrocolloïdes solubles ou gonflables dans l'eau, par exemple de l'alcool polyvinylique, de la pectine pulvérisée, de la gélatine, de la carboxyméthylcellulose, du < carbowax à haut poids moléculaire, du carboxypolyméthylène et d'autres substances analogues.
Les hydrocolloides ou les mélanges d'hydrocolloïdes peuvent tre incorporés à une substance gommeuse et visqueuse, naturelle ou synthétique, par exemple du caoutchouc naturel, du caoutchouc de silicone, du caoutchouc acrylonitrile, du caoutchouc polyuréthane, du polyisobutylène, de l'acétate-isobutyrate de saccharose et leurs équivalents. La substance gommeuse visqueuse agit comme liant pour les particules d'hydrocolloïde et, de plus, rend la composition adhésive finale élastique et flexible. Le polyisobutylène dans lequel est incorporé un mélange pulvérulent de pectine, de gélatine et de carboxyméthylcellulose donne les meilleurs résultats.
Lorsque les substances gommeuses et visqueuses, naturelles ou synthétiques sont employées, il peut tre désirable de les combiner à des plastifiants ou des solvants, par exemple huiles minérales ou pétrolatum, pour améliorer leur adhésivité et/ou pour leur conférer la consistance désirée.
En plus de l'utilisation de la composition ou pellicule adhésive selon l'invention telle quelle, il a été constaté que des résultats très satisfaisants sont obtenus lorsqu'une quantité notable de la composition adhésive selon l'invention est fixée sur un côté d'une pellicule mince et flexible, insoluble dans l'eau. Les pellicules insolubles dans l'eau pouvant tre employées comprennent notamment celles préparées à partir de polyéthylène et de polymères et copolymères du chlorure de vinylydène, d'hydrocarbures fluorohalogénés, de produits de condensation de l'éthylèneglycol sur l'acide téréphtalique, de polypropylènes, de polyamides, et les autres pellicules analogues insolubles dans l'eau. Les pellicules de polyéthylène sont préférées, bien que les autres pellicules insolubles dans Veau donnent également des résultats satisfaisants.
Des médicaments peuvent tre appliqués et retenus sur les surfaces du corps à traiter au moyen du pansement selon l'invention. A cet effet, le médicament peut tre appliqué sur la surface du pansement qui se trouvera en contact avec la surface à traiter. Le médicament peut tre appliqué sur la surface du pansement par poudrage, pulvérisation ou enduction. Parmi les médicaments utilisables, on peut citer l'insuline, les antibiotiques, par exemple l'amphotéricine, la tétracycline, des anesthésiques tels que la benzocame, des anti-inflammatoires, par exemple l'acétonide de triamcinolone.
La pellicule insoluble dans l'eau peut avoir une épaisseur de 0,0125 à 1,25 mm, de préférence de 0,0125 à 0,050 mm. La composition liante adhésive qui est appliquée sur une surface de la pellicule est en quantité suffisante pour couvrir complètement la surface blessée à traiter. Il est également possible d'appliquer une pellicule imperméable à l'eau sur le pansement selon l'invention après qu'il a été placé sur la surface à traiter.
La grandeur et l'épaisseur de la pellicule soluble dans l'eau dépend de la surface à traiter et de la durée d7ap- plication désirée.
La pellicule soluble dans l'eau employée dans l'invention est une pellicule que l'on peut se procurer en minces feuilles pliables. La durée d'application du pansement constitué par la pellicule soluble dans l'eau dépend évidemment de l'épaisseur de la pellicule. Plus cette dernière est mince, plus la durée d'application est brève.
En d'autres termes, plus la pellicule est mince, moins il faut de temps pour que celle-ci se dissolve naturellement.
I1 est préférable d'utiliser une pellicule soluble dans l'eau ayant une épaisseur d'environ 0,0025 à 0,25 ram. Lorsqu'un revtement insoluble dans l'eau est employé, ce dernier retarde la dissolution de la pellicule soluble dans l'eau.
Le pansement selon l'invention peut tre coupé dans les dimensions lui permettant de couvrir complètement la surface à traiter. Ensuite, le pansement peut tre simplement placé sur cette surface, I'humidité naturelle de celle-ci faisant adhérer la pellicule soluble dans l'eau à la surface affectée. Lorsqu'une matière insoluble dans l'eau est employée sur une surface et que le pansement subsiste après la durée de traitement désirée, il peut tre facilement enlevé et jeté, et peut tre remplacé par un nouveau pansement du mme type.
Exemple I
On colle une pellicule d'alcool polyvinylique sur une pellicule insoluble dans l'eau, par exemple de polyéthylène, en utilisant du polyisobutylène comme colle. On prépare tout d'abord une solution de polyisobutylène à 10 % dans du chloroforme, et on met cette solution sous pression avec 9 parties de < fréon . On dépose une mince couche de polyisolutylène sur une surface de la pellicule d'alcool polyvinylique par projection d'un aérosol de la solution de polyisobutylène. Après l'évaporation du solvant, on colle la pellicule de polyéthylène sur la pellicule d'alcool polyvinylique au moyen de rouleaux, conformément à la technique ordinaire de stratification.
Le stratifié ainsi obtenu peut ensuite tre coupé à la grandeur appropriée pour un traitement futur.
On obtient des résultats semblables en procédant comme décrit dans l'exemple 1, mais en remplaçant la pellicule d'alcool polyvinylique par une pellicule de méthyl-cellulose de grandeur équivalente.
Exemple 2
On chauffe 58 g de polyisobutylène à 70-800 C, puis on le mélange avec 42 g d'un mélange de pectine, de gélatine et de carboxyméthylcellulose sodique, après quoi on laisse le mélange refroidir, obtenant ainsi une substance pâteuse. On fait passer cette substance à travers un laminoir pour rendre le mélange plus uniforme, puis on aplatit la pâte dans une presse hydraulique pour l'amener à l'épaisseur désirée. Ensuite, on presse une mince pellicule de polyéthylène sur un côté, formant ainsi un stratifié que l'on coupe en bandes, carrés ou autres formes de grandeur désirée.
Exemple 3
On procède comme décrit dans l'exemple 2, sauf que l'on remplace les 58 g de polyisobutylène par un mélange de 56 g de polyisobutylène et de 2 g de pétrolatum. On obtient ainsi un pansement satisfaisant.
Exemple 4
On procède comme décrit dans l'exemple 2, sauf que l'on remplace les 58 g de polyisobutylène par un mélange de 55 g de polyisobutylène et de 1 g d'huile minérale, laquelle huile minérale a été préalablement chauffée à 70-800 C. On obtient ainsi un pansement satisfaisant.
Exemple 5
On procède comme décrit dans l'exemple 2, sauf que l'on remplace les 42 g de mélange de pectine, de gélatine et de carboxyméthylcellulose sodique par 42 g d'alcool polyvinylique en poudre fine.
Exemple 6
On procède comme décrit dans l'exemple 2, sauf que l'on remplace les 42 g de mélange de pectine, de gélatine et de carboxyméthylcellulose sodique par 42 g d'acacia.
Exemple 7
On procède comme décrit dans l'exemple 2, sauf que l'on remplace les 42 g de mélange de pectine, de gélatine et de carboxyméthylcellulose sodique par un mélange de 30g d'acacia et de 12g d'un mélange pulvérulent de gélatine, de pectine et de carboxyméthylcellulose sodique.
On obtient ainsi un pansement satisfaisant.
Exemple 8
On procède comme décrit dans l'exemple 2, sauf que l'on n'utilise pas de pellicule de polyéthylène et que l'on applique directement la composition liante pâteuse sur la surface à traiter.
Exemple 9
On procède comme décrit dans l'exemple 2, sauf que l'on remplace le polyisobutylène par 22 g d'acétateisobutyrate de saccharose et que l'on emploie 33 g d'un mélange de poudres de pectine, de gélatine et de carboxyméthylcellulose sodique. La composition liante ainsi formée peut ensuite tre employée directement comme pansement, ou la pellicule de polyéthylène insoluble dans l'eau peut tre appliquée sur cette composition avant l'usage.
Exemple 10
On procède comme décrit dans l'exemple 2, sauf que l'on remplace la pellicule de polyéthylène par une pellicule fluorohalogénocarbonée.
Pad
The subject of the present invention is a dressing which can be applied to wet surfaces of the body and which remains stuck to these surfaces for long periods of time.
Hitherto, dentists, dental surgeons, dermatologists and other practitioners of the medical art have not had a dressing which can be used locally on surfaces of the body, internal and external, wet or dry, for long periods of time. durations. In particular, attempts to use special tapes or the like on wet surfaces of the body have always failed. The humidity encountered at the time of application prevents the adhesion of the tape. Attempts to overcome this difficulty by means of ointments or the like have also failed, due to the fact that the moisture present quickly wash off ointments and the like.
It has now been found possible to prepare a new dressing which adheres instantly to body surfaces, and preferably to wet body surfaces, and most particularly to internal wet surfaces of the oral cavity. This new dressing is soft, flexible, easy to apply and, once applied, conforms to the curvature of the surface on which it sits, especially in the case of application to the surface of the oral cavity. The dressing according to the invention has no smell or taste and, after having been applied to the surface to be treated, it does not exfoliate on its own, but wears out slowly over a prolonged period of time. . This new dressing stays in place and supports all the activities of the person being treated.
For example, the person can drink, eat, sleep, talk, chew, or bite without any signs of irritation or toxicity.
It has been discovered that a new dressing which is particularly suitable for application to wet body surfaces, for example to intraoral surfaces, can be prepared from certain known materials which had never before been used for this purpose. . Essentially, the dressing according to the invention is based on the use of remarkable adhesive compositions or films.
The adhesive compositions or films which can be used for the implementation of the invention are those which, alone or in combination with other similar compositions, have been found to adhere to surfaces of the body. The adhesive compositions and films of the invention comprise one or more water soluble or swellable hydrocolloids, for example polyvinyl alcohol, powdered pectin, gelatin, carboxymethylcellulose, high molecular weight carbowax. , carboxypolymethylene and other similar substances.
The hydrocolloids or mixtures of hydrocolloids can be incorporated into a gummy and viscous, natural or synthetic substance, for example natural rubber, silicone rubber, acrylonitrile rubber, polyurethane rubber, polyisobutylene, acetate-isobutyrate. of sucrose and their equivalents. The viscous gummy substance acts as a binder for the hydrocolloid particles and, moreover, makes the final adhesive composition elastic and flexible. Polyisobutylene in which a pulverulent mixture of pectin, gelatin and carboxymethylcellulose is incorporated gives the best results.
When gummy and viscous, natural or synthetic substances are used, it may be desirable to combine them with plasticizers or solvents, for example mineral or petrolatum oils, in order to improve their adhesiveness and / or to give them the desired consistency.
In addition to the use of the adhesive composition or film according to the invention as such, it has been observed that very satisfactory results are obtained when a significant amount of the adhesive composition according to the invention is attached to one side of a thin, flexible film, insoluble in water. The water-insoluble films that can be used include in particular those prepared from polyethylene and polymers and copolymers of vinylydene chloride, fluorohalogenated hydrocarbons, condensation products of ethylene glycol with terephthalic acid, polypropylenes, polyamides, and other similar water-insoluble films. Polyethylene films are preferred, although other water-insoluble films also give satisfactory results.
Medicines can be applied and retained on the surfaces of the body to be treated by means of the dressing according to the invention. To this end, the medicament can be applied to the surface of the dressing which will be in contact with the surface to be treated. The medicament can be applied to the surface of the dressing by powdering, spraying or coating. Among the medicaments which can be used, mention may be made of insulin, antibiotics, for example amphotericin, tetracycline, anesthetics such as benzocam, anti-inflammatory drugs, for example triamcinolone acetonide.
The water-insoluble film can have a thickness of 0.0125 to 1.25 mm, preferably 0.0125 to 0.050 mm. The adhesive binder composition which is applied to a surface of the film is in an amount sufficient to completely cover the injured surface to be treated. It is also possible to apply a waterproof film to the dressing according to the invention after it has been placed on the surface to be treated.
The size and thickness of the water soluble film depends on the surface to be treated and the desired application time.
The water soluble film employed in the invention is a film which can be obtained in thin, foldable sheets. The duration of application of the dressing consisting of the water-soluble film obviously depends on the thickness of the film. The thinner the latter, the shorter the application time.
In other words, the thinner the film, the less time it takes for it to dissolve naturally.
It is preferable to use a water soluble film having a thickness of about 0.0025 to 0.25 ram. When a water-insoluble coating is employed, the coating retards the dissolution of the water-soluble film.
The dressing according to the invention can be cut in the dimensions allowing it to completely cover the surface to be treated. Then, the dressing can simply be placed on this surface, the natural humidity of the latter causing the water-soluble film to adhere to the affected surface. When a material insoluble in water is used on a surface and the dressing remains after the desired treatment time, it can be easily removed and discarded, and can be replaced by a new dressing of the same type.
Example I
A film of polyvinyl alcohol is glued onto a film insoluble in water, for example of polyethylene, using polyisobutylene as an adhesive. First, a 10% solution of polyisobutylene in chloroform is prepared, and this solution is pressurized with 9 parts of freon. A thin layer of polyisolutylene is deposited on one surface of the film of polyvinyl alcohol by spraying an aerosol of the polyisobutylene solution. After the solvent has evaporated, the polyethylene film is glued to the polyvinyl alcohol film by means of rollers, according to the ordinary laminating technique.
The laminate thus obtained can then be cut to the appropriate size for a future treatment.
Similar results are obtained by proceeding as described in Example 1, but replacing the film of polyvinyl alcohol with a film of methyl cellulose of equivalent size.
Example 2
58 g of polyisobutylene are heated to 70-800 C, then mixed with 42 g of a mixture of pectin, gelatin and sodium carboxymethylcellulose, after which the mixture is allowed to cool, thus obtaining a pasty substance. This substance is passed through a rolling mill to make the mixture more uniform, then the dough is flattened in a hydraulic press to bring it to the desired thickness. Then, a thin film of polyethylene is pressed onto one side, thereby forming a laminate which is cut into strips, squares or other shapes of any desired size.
Example 3
The procedure is as described in Example 2, except that the 58 g of polyisobutylene are replaced by a mixture of 56 g of polyisobutylene and 2 g of petrolatum. A satisfactory dressing is thus obtained.
Example 4
The procedure is as described in Example 2, except that the 58 g of polyisobutylene are replaced by a mixture of 55 g of polyisobutylene and 1 g of mineral oil, which mineral oil has been heated beforehand to 70-800 C A satisfactory dressing is thus obtained.
Example 5
The procedure is as described in Example 2, except that the 42 g of mixture of pectin, gelatin and sodium carboxymethylcellulose are replaced by 42 g of fine powdered polyvinyl alcohol.
Example 6
The procedure is as described in Example 2, except that the 42 g of mixture of pectin, gelatin and sodium carboxymethylcellulose are replaced by 42 g of acacia.
Example 7
The procedure is as described in Example 2, except that the 42 g of a mixture of pectin, gelatin and sodium carboxymethylcellulose are replaced by a mixture of 30 g of acacia and 12 g of a powder mixture of gelatin, pectin and sodium carboxymethylcellulose.
A satisfactory dressing is thus obtained.
Example 8
The procedure is as described in Example 2, except that no polyethylene film is used and that the pasty binder composition is applied directly to the surface to be treated.
Example 9
The procedure is as described in Example 2, except that the polyisobutylene is replaced by 22 g of sucrose acetateisobutyrate and that 33 g of a mixture of pectin, gelatin and sodium carboxymethylcellulose powders are used. The binder composition thus formed can then be used directly as a dressing, or the film of polyethylene insoluble in water can be applied to this composition before use.
Example 10
The procedure is as described in Example 2, except that the polyethylene film is replaced by a fluorohalocarbon film.
