Abstract

The invention relates to a polymer tube having a tube body. This comprises a polymeric base material and at least one neutralizing additive for generating an odor barrier between a tube lumen and an external environment surrounding the polymer tube. The neutralizing additive has an adsorbent for neutralizing odor-forming molecules and a catalytic material for splitting odor-forming molecules. This results in a polymer tube, in which a release of odor-forming compounds into an external environment is at least largely prevented.

Die vorliegende Patentanmeldung nimmt die Priorität der deutschen Patentanmeldung DE 10 2015 222 484.8 in Anspruch, deren Inhalt durch Be- zugnahme hierin aufgenommen wird. The present patent application claims the priority of German patent application DE 10 2015 222 484.8, the content of which is incorporated herein by reference.
Die Erfindung betrifft einen Polymerschlauch, insbesondere für eine medizinische oder pharmazeutische Anwendung. Ein Beispiel für eine derartige medizinische Anwendung ist ein Rektalkatheter. Ein derartiger Polymer- schlauch kann zur Verlängerung eines Darmausgangs genutzt werden. The invention relates to a polymer tube, in particular for a medical or pharmaceutical application. An example of such a medical application is a rectal catheter. Such a polymer tube can be used to lengthen an intestinal outlet.
Polymerschläuche sind in vielfältiger Ausführung bekannt. Polymer hoses are known in a variety of designs.
Die EP 2 620 168 AI beschreibt die Herstellung eines Schlauchs mit Ge- ruchsbarriere für den Einsatz als Katheter. EP 2 620 168 A1 describes the production of a tube with odor barrier for use as a catheter.
In der EP 2 001 671 Bl wird ein mehrschichtiges Material beschrieben, das sich für den Einsatz in geruchsintensiven Bereichen, z.B. als geruchshemmende Substanz in einem Katheterbeutel eignet. EP 2 001 671 B1 describes a multilayered material which is suitable for use in odor-intensive areas, e.g. as an odor-inhibiting substance in a catheter bag.
In der WO 2013/043 226 AI wird ein geruchshemmendes Material beschrieben, das für den Einsatz in Kathetern oder Fäkalienbeuteln geeignet ist. Die US 2008/0057019 AI beschreibt Zusammensetzungen, die die Funktion einer Geruchsbarriere haben. Die US 7,446,132 B2 beschreibt ein Zeo- lith-Additiv. Je nach Anwendung kann gewünscht sein, dass ein Geruch eines im Polymerschlauch transportierten Mediums nicht nach außen dringt, so dass es zu keiner unerwünschten Geruchsbelästigung einer äußeren Umgebung kommt. Entsprechend ist es eine Aufgabe der vorliegenden Erfindung, ei- nen Polymerschlauch der eingangs genannten Art derart weiterzubilden, dass eine Freisetzung von geruchsbildenden Verbindungen in eine äußere Umgebung zumindest weitgehend verhindert ist. In WO 2013/043 226 Al an odor-inhibiting material is described, which is suitable for use in catheters or Fäkalienbeuteln. US 2008/0057019 A1 describes compositions which have the function of an odor barrier. No. 7,446,132 B2 describes a zeolite additive. Depending on the application, it may be desired that a smell of a medium transported in the polymer tube does not penetrate to the outside, so that there is no undesirable odor nuisance of an external environment. Accordingly, it is an object of the present invention, a polymer hose of the type mentioned in such a way that a release of odor-forming compounds in an external environment is at least largely prevented.
Diese Aufgabe ist erfindungsgemäß gelöst durch einen Polymerschlauch mit den im Anspruch 1 angegebenen Merkmalen. This object is achieved by a polymer tube having the features specified in claim 1.
Das im Neutralisations-Additiv vorliegende Adsorbens und das katalytische Material sorgen für eine Neutralisierung geruchsbildender Moleküle. Das Adsorbens kann insbesondere Schwefelverbindungen neutralisieren. Geruchsbildende Schwefelverbindungen sind u.a. Schwefelwasserstoff, Methanthiol, Allylmethylsulfid, Disulfide (wie z.B. Dimethyldisulfid, Me- thylpropyldisulfid, Dipropyldisulfid, cis-Propenylpropyldisulfid, trans- Propenylpropyldisulfid) und Trisulfide (wie z.B. Dimethyltrisulfid). Das Adsorbens kann eine große aktive Oberfläche aufweisen. Das Adsorbens weist insbesondere eine spezifische Oberfläche von 100 - 600 m2/g, bevorzugt von 250 - 500 m2/g, besonders bevorzugt von 300 - 400 m2/g, auf. Die aktive Oberfläche des Adsorbens wird dabei nach der BET(Brunauer, Emmett, Teller)-Methode (vgl. DIN 66131 und ISO 9277) bestimmt und wird auch als BET-Oberfläche bezeichnet. Die BET-Oberfläche wird am pulverförmigen Material oder an Tabletten entsprechend DIN 66131 bestimmt. The adsorbent present in the neutralization additive and the catalytic material provide neutralization of odoriferous molecules. In particular, the adsorbent can neutralize sulfur compounds. Odor-forming sulfur compounds include hydrogen sulfide, methanethiol, allyl methyl sulfide, disulfides (such as dimethyl disulfide, methyl propyl disulfide, dipropyl disulfide, cis propenyl propyl disulfide, trans propenyl propyl disulfide) and trisulfides (such as dimethyl trisulfide). The adsorbent may have a large active surface area. In particular, the adsorbent has a specific surface area of 100-600 m 2 / g, preferably of 250-500 m 2 / g, particularly preferably of 300-400 m 2 / g. The active surface of the adsorbent is determined by the BET (Brunauer, Emmett, Teller) method (see DIN 66131 and ISO 9277) and is also referred to as BET surface area. The BET surface area is determined on the powdery material or on tablets according to DIN 66131.
Das katalytische Material kann für eine Aufspaltung geruchsbildender und damit störender Moleküle sorgen. Das Adsorbens und das katalytische Ma- terial sind daher zur Ausbildung der Geruchsbarriere geeignet, indem die geruchsbildenden Moleküle entweder adsorbiert oder in kleinere, nicht mehr geruchsbildende Moleküle aufgespalten werden. Das katalytische Material kann auch dann noch geruchshemmend und jedenfalls geruchs- mindernd wirken, wenn eine Beladung des Adsorbens bereits eine kritische Beladungsgrenze überschreitet. The catalytic material can cause a breakdown of odoriferous and thus disturbing molecules. The adsorbent and the catalytic terial are therefore suitable for forming the odor barrier by the odor-forming molecules are either adsorbed or split into smaller, no longer odor-forming molecules. The catalytic material can still have an odor-inhibiting and odor-reducing effect even if a loading of the adsorbent already exceeds a critical loading limit.
Als polymeres Grundmaterial kann Silikon oder ein thermoplastisches Elastomer (TPE) zum Einsatz kommen. Der Polymerschlauch kann auch außerhalb einer medizinischen oder pharmazeutischen Anwendung zum Einsatz kommen, nämlich generell dort, wo durch eine Diffusion von geruchsintensiven Molekülen durch die Schlauchwand anwendungsbedingt mit einer unerwünschten Geruchsentwicklung zu rechnen ist. Derartige weitere Polymerschlauch- Anwendungen sind beispielsweise Gasleitungen aus Kunststoff. Bei diesen Polymerschlauch- Anwendungen ermöglicht ein entsprechendes Neutralisations-Additiv beispielsweise eine Unterscheidung einer Wanddiffusion von einer echten Leckage und somit eine Le- ckagedetektion. Ein weiteres Anwendungsbeispiel für einen solchen Polymerschlauch ist eine Rohrleitung und deren Kompensatoren, wie sie zum Beispiel bei Erdölleitungen oder Biogasanlagen Verwendung finden. As a polymeric base material, silicone or a thermoplastic elastomer (TPE) can be used. The polymer tube can also be used outside of a medical or pharmaceutical application, namely generally where, due to the application, an undesirable odor development is to be expected due to a diffusion of odorous molecules through the tube wall. Such other polymer hose applications are, for example, gas lines made of plastic. In these polymer hose applications, for example, a corresponding neutralization additive makes it possible to distinguish wall diffusion from true leakage and thus leakage detection. Another application example of such a polymer hose is a pipeline and their compensators, as used for example in oil lines or biogas plants.
Stoffgemische, die schwefelbasierte Geruchsstoffe enthalten, treten in Erdölraffinerien, bei dem Transport von Erdöl, bei der Herstellung von Biogas und Biodiesel auf. In diesen Bereichen ist eine Geruchsreduzierung durch die Bindung dieser Geruchsstoffe an ein Neutralisations-Additiv möglich. Substances that contain sulfur-based odors are found in oil refineries, in the transportation of oil, in the production of biogas and biodiesel. In these areas, odor reduction is possible by binding these odorous substances to a neutralization additive.
In Faultürmen, Kläranlagen, Sanitäreinrichtungen wie mobilen Toiletten (u.a. in Wohnmobilen), in der Kanalisation oder auch auf Mülldeponien entstehen schwefelhaltige Gase, deren schwefelhaltige Komponenten einen starken Geruch verursachen. Eine Geruchsminderung kann erreicht werden, wenn mit einem Neutralisations-Additiv versehene Polymerschläuche verwendet werden. Schwefelhaltige chemische Erzeugnisse, wie z.B. Mercaptane, besitzen einen starken Eigengeruch. Die Geruchsbelästigung während des Herstellungsprozesses, der Lagerung und des Transports kann durch Verwendung von einem mit einem Neutralisations-Additiv versehenen Polymerschlauch gemindert werden. In digestion towers, sewage treatment plants, sanitary facilities such as mobile toilets (including in mobile homes), in the sewage system or in landfills, sulfur-containing gases are produced, the sulfur-containing components of which create a cause a strong smell. Odor reduction can be achieved when using polymer tubing provided with a neutralizing additive. Sulfur-containing chemicals, such as mercaptans, have a strong odor. The odor nuisance during the manufacturing process, storage and transportation can be alleviated by using a polymer tube provided with a neutralization additive.

Alternativ oder zusätzlich kann nach Anspruch 3 das katalytische Material als zusätzlich zum Adsorbens vorhandene Komponente vorliegen. Ein derart in dem Neutralisations-Additiv vorliegendes zusätzliches katalytisch aktives Material ist geeignet, geruchsbildende Moleküle aufzuspalten. Dabei kann es auch Moleküle aufspalten, die aufgrund ihrer Größe nicht an dem Adsorbermaterial adsorbiert werden können. Nach der Aufspaltung liegen diese Moleküle als kleinere Moleküle vor und können im folgenden Schritt am Adsorbens adsorbiert werden und aufgrund seiner katalytischen Funktion weiter aufgespalten werden. Das in dem Neutralisations-Additiv vorliegende katalytische Material kann ein Metall, insbesondere mit einer Oxidations stufe ungleich 0, oder eine nichtmetallische Komponente bzw. eine nichtmetallische Verbindung umfassen. Bei einer alternativen Ausgestaltung des katalytischen Materials kann dieses sowohl eine metallische als auch eine nichtmetallische Komponente umfassen. Insofar as the catalytic material is present as a component of the adsorbent according to claim 2, the adsorbent agrees the functions "neutralization" and "catalytic elimination of offensive odors". Alternatively or additionally, according to claim 3, the catalytic material may be present as a component in addition to the adsorbent. Such an additional catalytically active material present in the neutralization additive is suitable for splitting odor-forming molecules. It can also split molecules that can not be adsorbed on the adsorbent due to their size. After cleavage, these molecules are present as smaller molecules and can be adsorbed on the adsorbent in the following step and further split due to its catalytic function. The catalytic material present in the neutralization additive may comprise a metal, in particular having an oxidation state not equal to 0, or a non-metallic component or a non-metallic compound. In an alternative embodiment of the catalytic material This may include both a metallic and a non-metallic component.
Für metallhaltige Verbindungen nach Anspruch 4, die das katalytisch akti- ve Material umfasst, eignen sich insbesondere die Metalle Mangan, Zink, Eisen oder Edelmetalle oder eine Kombination von mindestens zweier dieser Metalle. Auch Edelstahl kann zum Einsatz kommen. For metal-containing compounds according to claim 4, which comprises the catalytically active material, in particular the metals manganese, zinc, iron or noble metals or a combination of at least two of these metals are suitable. Also stainless steel can be used.
Besonders geeignete Edelmetalle nach Anspruch 5 sind ausgewählt aus Platin, Gold, Silber und Kupfer oder einer Kombination von mindestens zwei dieser Edelmetalle. Bei einer alternativen Ausgestaltung des Polymer- schlauchs kann als metallhaltige Verbindung auch eine solche Verbindung verwendet werden, bei der das Metallelement nicht als reines Metall, d.h. in der Oxidationsstufe 0 vorliegt. Auch Kombinationen aus einem reinen Metall und Metallelement im nicht metallischen Zustand können zum Einsatz kommen. Particularly suitable noble metals according to claim 5 are selected from platinum, gold, silver and copper or a combination of at least two of these noble metals. In an alternative embodiment of the polymer tube, the metal-containing compound may also be a compound in which the metal element is not used as a pure metal, i. in the oxidation state 0 is present. Combinations of a pure metal and metal element in the non-metallic state can also be used.
Enthält das Neutralisations-Additiv Kupfer, liegt dieses bevorzugt in einem Anteil von mindestens 0,1 Gew.-%, besonders von 0,1 bis 10 Gew.-% vor. Dieser Kupferanteil kann sich in dem Adsorbens, enthaltend die katalyti- sche Funktion, oder sich in dem weiteren katalytisch aktiven Material befinden. Contains the neutralization additive copper, this is preferably in a proportion of at least 0.1 wt .-%, especially from 0.1 to 10 wt .-% before. This proportion of copper may be present in the adsorbent containing the catalytic function or in the further catalytically active material.
Enthält das Neutralisations-Additiv Mangan, liegt dieses bevorzugt in ei- nem Anteil von mindestens 10 Gew.-%, besonders von 10 bis 15 Gew.-% vor. Dieser Mangananteil kann sich in dem Adsorbens, enthaltend die kata- lytische Funktion, oder sich in dem weiteren katalytisch aktiven Material befinden. Enthält das Neutralisations-Additiv Zink, liegt dieses bevorzugt in einem Anteil von mindestens 20 Gew.-%, besonders von 20 bis 40 Gew.-% vor. Dieser Zinkanteil kann sich in dem Adsorbens, enthaltend die katalytische Funktion, oder sich in dem weiteren katalytisch aktiven Material befinden. If the neutralization additive contains manganese, this is preferably present in a proportion of at least 10% by weight, especially from 10 to 15% by weight. This manganese fraction may be present in the adsorbent containing the catalytic function or in the further catalytically active material.

This zinc fraction may be in the adsorbent containing the catalytic function or in the further catalytically active material.
Ein Molekularsieb nach Anspruch 6 stellt eine besonders effektive Variante eines Neutralisations-Additivs dar. Das Molekularsieb kann poröse Strukturen, insbesondere poröse kristalline Strukturen bereitstellen, deren Porengröße gezielt den zu bindenden geruchsbildenden Molekülen angepasst werden kann. Bei Einsatz eines Molekularsiebs kann der Katalysator so gewählt sein, dass er Moleküle aufspaltet, für deren unaufgespaltene Form die Poren des Molekularsiebs zu klein sind. A molecular sieve according to claim 6 represents a particularly effective variant of a neutralization additive. The molecular sieve can provide porous structures, in particular porous crystalline structures, whose pore size can be tailored to the odor-forming molecules to be bound.

Bei dem Zeolith der Topologie BEA handelt es sich bevorzugt um einen synthetisch hergestellten Zeolithen. Auch ein anderes Zeolith-Material mit einem dreidimensionalen Kanalsys- tem kann zum Einsatz kommen. Als Beispiele sind Zeolithe mit MFI, FAU und MO Topologie zu nennen. Bezüglich der Nomenklatur der vorgenannten Topologien wird auf den„Atlas of Zeolite Framework Types", Ch. Baerlocher, 5th Edition, 2001 verwiesen, der eine Übersicht über die ver- schiedenen Topologien der Zeolithstrukturen liefert und dessen Offenbarung diesbezüglich in die Beschreibung aufgenommen wird. A zeolite of the topology BEA according to claim 9 represents a particularly suitable neutralization additive. The zeolite of the topology BEA is preferably a synthetically produced zeolite. Another zeolite material with a three-dimensional channel system can also be used. Examples include zeolites with MFI, FAU and MO topology. With regard to the nomenclature of the aforementioned topologies, reference is made to the "Atlas of Zeolite Framework Types", Ch. Baerlocher, 5th Edition, 2001, which provides an overview of provides various topologies of zeolite structures and the disclosure of which is incorporated herein in the description.
Der Zeolith hat dabei insbesondere die Funktion, die geruchsbildenden Moleküle zu adsorbieren. Dies erfolgt aufgrund der spezifischen Zeolith- struktur, die Kanäle und/oder Hohlräume aufweist, die für Moleküle einer bestimmten Größe zugänglich sind. The zeolite has in particular the function of adsorbing the odoriferous molecules. This is due to the specific zeolite structure having channels and / or cavities accessible to molecules of a particular size.
Das katalytische Material in dem Neutralisations-Additiv kann entweder als eigene Verbindung neben dem Adsorbens vorliegen, insbesondere als metallhaltige Verbindung, ganz besonders in Form eines Oxids, Hydroxids, Carbonats oder Phosphats. The catalytic material in the neutralization additive may be present either as a separate compound adjacent to the adsorbent, especially as a metal-containing compound, more particularly in the form of an oxide, hydroxide, carbonate or phosphate.
Liegt das Adsorbens z.B. als Zeolith vor, kann dieser Zeolith zusätzlich metallhaltige Komponenten beinhalten, die entweder in Form einer reinen metallischen Phase, das bedeutet in der Oxidationsstufe 0, oder in Form von Metallionen vorliegen. In diesem Fall liegt das katalytische Material des Neutralisations-Additivs in der Zeolithstruktur selber vor. Partikel mit einer Partikelgröße von 0,1 μηι bis 50,0 μηι, insbesondere von 1,0 bis 10,0 μηι nach Anspruch 10 haben sich für das Neutralisations- Additiv als besonders geeignet herausgestellt. Insbesondere das weitere katalytische Material weist eine Partikelgröße von 0,1 μηι bis 50,0 μηι, insbesondere von 1,0 bis 10,0 μηι auf. Zusätzlich kann das Adsorbens eine Partikelgröße von 0,1 μηι bis 50,0 μηι, insbesondere von 1,0 bis 10,0 μηι aufweisen. If the adsorbent is e.g. as zeolite, this zeolite may additionally contain metal-containing components which are present either in the form of a pure metallic phase, ie in the oxidation state 0, or in the form of metal ions. In this case, the catalytic material of the neutralization additive is present in the zeolite structure itself. Particles having a particle size of 0.1 μηι to 50.0 μηι, in particular from 1.0 to 10.0 μηι according to claim 10 have been found to be particularly suitable for the neutralization additive. In particular, the further catalytic material has a particle size of 0.1 μηι to 50.0 μηι, in particular from 1.0 to 10.0 μηι. In addition, the adsorbent can have a particle size of from 0.1 μm to 50.0 μm, in particular from 1.0 to 10.0 μm.
Eine Additivpaste nach Anspruch 1 1 ermöglicht eine exakte Vorbereitung einer Zusammensetzung des Neutralisations- Additivs. Die Paste ermöglicht eine ausreichende Materialdurchmischung mit dem polymeren Grundmaterial. Die Herstellung der Additivpaste kann durch Dispergieren und insbesondere durch Fein-Dispergieren erfolgen. Ein Zeolith- Anteil nach Anspruch 12 führt zu einer besonders geeigneten Zusammensetzung der Additivpaste. An additive paste according to claim 1 1 allows an exact preparation of a composition of the neutralization additive. The paste allows sufficient material mixing with the polymeric base material. The preparation of the additive paste can be carried out by dispersing and in particular by fine dispersion. A zeolite content according to claim 12 leads to a particularly suitable composition of the additive paste.

Beispiel 1 example 1
100 Teile Silikon-Grundmaterial 100 parts silicone base material
1 ,6 Teile Vernetzer 1, 6 parts crosslinker
5 Teile Additivpaste 5 parts of additive paste
Als Grundmaterial kann ein peroxidisch vernetztes Silikon zum Einsatz kommen. Dieses Silikon kann eine Shore-Härte im Bereich zwischen 30 A und 80 A und insbesondere eine Shore-Härte von 50 A haben. Es können ein- oder mehrkomponentige Silikone zum Einsatz kommen. Es können hochtemperaturvernetzende oder raumtemperaturvernetzende Silikone zum Einsatz kommen. Anstelle von Silikon als Grundmaterial kann als Grundmaterial ein thermoplastisches Elastomer zum Einsatz kommen. The base material can be a peroxide cross-linked silicone. This silicone can have a Shore hardness in the range between 30 A and 80 A and in particular a Shore hardness of 50 A. One- or multi-component silicones can be used. High-temperature-curing or room-temperature-curing silicones can be used. Instead of silicone as the base material, a thermoplastic elastomer can be used as the base material.
Als Vernetzer kann ein peroxidischer Vernetzer, ein Platin- Vernetzer oder ein UV- Vernetzer zum Einsatz kommen. The crosslinker used can be a peroxidic crosslinker, a platinum crosslinker or a UV crosslinker.
Die Additivpaste hat bei diesem Ausführungsbeispiel folgende Zusammensetzung: 47,9 Gew.-% BEA-Zeolith The additive paste in this exemplary embodiment has the following composition: 47.9% by weight of BEA zeolite
13,1 Gew.-% Mangan 13.1 wt .-% manganese
7,7 Gew.-% Kupfer 7.7% by weight of copper
Die Additivpaste umfasst regelmäßig noch eine fließfähige Trägerkompo- nente. Grundsätzlich ist es aber auch möglich, die vorstehend erwähnten Komponenten BEA-Zeolith, Mangan und Kupfer in trockener Form zuzugeben. The additive paste regularly comprises a flowable carrier component. In principle, however, it is also possible to add the abovementioned components BEA zeolite, manganese and copper in dry form.
Beispiel 2 Example 2
Vom Ausführungsbeispiel 1 unterscheidet sich das Ausführungsbeispiel 2 nur durch die Zusammensetzung der Additivpaste. Diese ist folgende: From the embodiment 1, the embodiment 2 differs only by the composition of the additive paste. This is the following:
47,9 Gew.-% BEA-Zeolith 47.9 wt .-% BEA zeolite
33,8 Gew.-% Zink 33.8% by weight of zinc
2,1 Gew.-% Kupfer 2.1% by weight of copper
Silikonöl als Trägerfluid Die Menge des Silikonöls als Trägerfluid ist hierbei unkritisch. Das Trä- gerfluid dient dazu, die Viskosität der Additivpaste einzustellen. Silicone oil as a carrier fluid The amount of silicone oil as a carrier fluid is not critical here. The carrier fluid serves to adjust the viscosity of the additive paste.
Bei beiden Ausführungsbeispielen wird die Additivpaste zunächst durch Dispergieren und anschließendes Fein-Dispergieren hergestellt und dann dem Silikon-Grundmaterial beigemischt. Es erfolgt dann eine Extrusion des so hergestellten Compounds zu einem Polymerschlauch. In both embodiments, the additive paste is first prepared by dispersing and then finely dispersing and then admixing the silicone base material. An extrusion of the compound thus produced then takes place to form a polymer tube.
Dieser Polymerschlauch findet in der Medizintechnik, insbesondere als Rektalkatheter Verwendung. Der Polymerschlauch kann die Funktion eines Drainage schlauchs haben. This polymer tube is used in medical technology, especially as a rectal catheter. The polymer tube may have the function of a drainage hose.
Auch eine Anwendung des Polymerschlauchs in der Pharmazie ist möglich, beispielsweise als Abfüllschlauch für Medikamente. Auch eine an- derweitige Anwendung, beispielsweise als Gas- oder Ölleitung, ist möglich. An application of the polymer tube in pharmacy is possible, for example as a filling tube for drugs. Another application, for example as a gas or oil line, is also possible.
