Description

Haftverband für intravenöse periphere Kanülen Adhesive bandage for intravenous peripheral cannulas
Die Erfindung betrifft einen Haftverband für intravenöse peri¬ phere Kanülen aus einem mikroporösen Material mit einer Ausspa¬ rung zur Aufnahme der Kanüle.The invention relates to an adhesive bandage for intravenous peripheral cannulas made of a microporous material with a recess for receiving the cannula.
Haftverbände der obengenannten Art sind bekannt. Sie dienen der Fixierung von Venenkathetern, die über längere Zeit eingesetzt werden und sollen zugleich die Einstichstelle steril abdecken und gegen das Eindringen von Mikroorganismen schützen sowie das Auftreten von Phlebitis und anderen Komplikationen verhindern. Bei längerfristigen und langfristigen venösen Katherisierungen soll zudem der dauerhaft richtige Sitz des Katheters gewährlei¬ stet sein. Derartige HaftverbMnde müssen schweiß- und sauer- stoffdurchlässig sein und zugleich das Eindringen von Flüssigkei¬ ten verhindern.Adhesive bandages of the above type are known. They are used to fix venous catheters that are used over a long period of time and are also intended to cover the puncture site in a sterile manner and protect them against the penetration of microorganisms and prevent the occurrence of phlebitis and other complications. In the case of long-term and long-term venous catheterization, the permanent correct seating of the catheter should also be guaranteed. Adhesive bonds of this type must be permeable to sweat and oxygen and at the same time prevent the penetration of liquids.
Ferner ist bekannt, derartige Haftverbände teilweise transpa¬ rent zu gestalten, um die Einstichstelle und den richtigen Sitz des Katheters- kontrollieren zu können.It is also known to make such adhesive bandages partially transparent so that the puncture site and the correct fit of the catheter can be checked.
Bei den herkömmlichen Haftverbänden für intravenöse periphere Kanülen besteht aber das Problem, das insbesondere bei länger¬ fristigen Kathetisierungen an der Einstichstelle Entzündungen auftreten, beispielsweise eine Thrombophlebitis. Derartige Ent¬ zündungen bedürfen der Behandlung, was die Entfernung des Katheters und das Anlegen eines neuen an einer anderen Katheti- sierungsstelle erforderlich macht. Dies ist aus medizinischen Gründen unerwünscht und, abgesehen davon, zeitraubend und ko- εtenintensiv und für den Patienten unangenehm. Es besteht daher ein Bedürfnis nach Haftverbanden für intravenö¬ se periphere Kanülen, mit denen das Plebitiεriεiko deutlich vermindert werden kann. Derartige HaftverbMnde sollen zugleich einen festen Sitz des Venenkatheters garantieren, schweiß- und sauerεtoffdurchlSssig sein, das Eindringen von Mikroorganismen und Flüssigkeiten verhindern, hautfreundlich auch bei längerer Verweildauer sein und zudem einfach und sicher in der Handhabung abwasch- und beschriftbar.With the conventional adhesive bandages for intravenous peripheral cannulas, however, there is the problem that inflammation occurs at the puncture site in particular in the case of long-term cathetization, for example thrombophlebitis. Such inflammations require treatment, which necessitates the removal of the catheter and the application of a new one at another catheterization site. For medical reasons, this is undesirable and, apart from that, time-consuming and costly and uncomfortable for the patient. There is therefore a need for adhesive bandages for intravenous peripheral cannulas with which the risk of plebitis can be significantly reduced. Adhesive bonds of this type are also intended to guarantee a firm fit of the venous catheter, to be permeable to sweat and oxygen, to prevent the penetration of microorganisms and liquids, to be skin-friendly even after a longer period of time and, moreover, to be washable and inscribable in a simple and safe manner.
Dieses Ziel wird mit den Haftverbanden der eingangs geschilder¬ ten Art erreicht, die dadurch gekennzeichnet sind, daß sie eine entzündungshemmende Substanz auf ihrer Hautseite enthalten.This goal is achieved with the adhesive bandages of the type described at the outset, which are characterized in that they contain an anti-inflammatory substance on their skin side.
Vorzugsweise wird als entzündungshemmende Substanz ein trans- derma] wirkendes Mittel eingesetzt, etwa Glyceryltrinitrat und/oder NSAID = Non-Steroidal-Z^iiππanrβtory-Drugs, nicht steroide entzi jπgshβπrende Mittel GTN hat sich überraschend bei der Thrombophlebitiε-Pro- phylaxe als sehr wirksam erwiesen. Es wird langsam durch die Haut aufgenommen und verbreitet im Bereich der Auftragungsstel¬ le und der näheren Umgebung seine entzündungshemmende Wirkung. Bei Verwendung von GTN in Haftverbänden nimmt das Phlebitiεriεi- ko εtark ab und kann die Verweildauer der Haftverbände und der intravenösen peripheren Kanülen deutlich verlängert werden.Preferably, a trans- derma is used] acting agents as anti-inflammatory substance, such as glyceryl trinitrate and / or NSAID = non-steroidal-Z ^ iiππanrβtory-drugs, non-steroidal entzi jπgsh β πrende means GTN has prophylaxis surprising in Thrombophlebitiε-Pro- as proven very effective. It is slowly absorbed through the skin and spreads its anti-inflammatory effect in the area of the application site and in the immediate vicinity. When GTN is used in adhesive bandages, the phlebitis risk decreases considerably and the length of time that the adhesive bandages and the intravenous peripheral cannulae can be extended significantly.
Die an aktivem Wirkstoff benötigten Mengen liegen im Bereich von 1, biε 10 mg/d, vorzugsweise 3 biε 7 mg/d; beεonders bevor¬ zugt ist eine Menge im Bereich von 5 mg GTN/d.The amounts of active ingredient required are in the range from 1 to 10 mg / d, preferably from 3 to 7 mg / d; an amount in the range of 5 mg GTN / d is particularly preferred.
Die entzündungshemmende Substanz ist im Haftverband vorzugswei¬ se in der Nähe der Einstichstelle angeordnet. Wegen der Über die Kontaktstelle hinaus'auftretenden Wirkung tranεdeπnaler Substanzen ist es jedoch nicht notwendig, daß die Einstichstel¬ le direkt abgedeckt wird; dies ist auch hSufig unerwünscht, um ein Einsickern des Mittels in die Einstichstelle oder eine Be¬ einträchtigung seiner Wirksamkeit durch daraus austretende Flüssigkeit oder Sekrete zu verhindern. Die entzündungshemmende Substanz kann aber auch über den gesamten Bereich des Haftverban¬ des oder an mehreren einzelnen Stellen angeordnet sein. Vorzugsweise wird die entzündungshemmende Substanz auf das hautseitige Material des Haftverbandes aufgetragen oder ist auf oder in einem auf der Innenseite angeordneten Träger vorhanden; es kann aber auch im Material des Haftverbandes selbst enthal¬ ten sein, wenn die kontrollierte Abgabe an die Haut gewährlei¬ stet ist. Maßnahmen zur Steuerung der Abgabegeschwindigkeit der transdermal wirksamen Subtanz sind dem Fachmann bekannt. Falls erforderlich ist die entzündungshemmende Sustanz durch ein Sperrschicht, etwa eine hierfür gebräuchliche undurchlässige Folie, gegen ein Durchtreten durch den Haftverband nach außen gesichert.The anti-inflammatory substance is preferably arranged in the adhesive dressing near the puncture site. However, due to over the pad out 'effect occurring tranεdeπnaler substances, it is not necessary that the Einstichstel¬ is le directly covered; this is also often undesirable in order to prevent the agent from seeping into the puncture site or from impairing its effectiveness by the liquid or secretions escaping therefrom. However, the anti-inflammatory substance can also be arranged over the entire area of the adhesive bond or at several individual locations. The anti-inflammatory substance is preferably applied to the skin-side material of the adhesive dressing or is present on or in a carrier arranged on the inside; however, it can also be contained in the material of the adhesive dressing itself if the controlled release to the skin is guaranteed. Measures to control the delivery rate of the transdermally active substance are known to the person skilled in the art. If necessary, the anti-inflammatory substance is protected against external penetration by a barrier layer, such as an impermeable film used for this purpose.
Der erfindungsgemäße Haftverband ist für alle Formen herkömm¬ licher Kanülen für die intravenöse periphere Verwendung geeig¬ net, also beispielsweise für Butterfly- oder Flügelkanülen, aber auch für flügellose Kanülen und für Kanülen mit Zuspritz- ventilen. Als Material für den Haftverband dienen übliche schweiß- und sauerstoffdurchlässige Materialien, die die Ein¬ stichstelle sicher abdecken und gegen das Eindringen von Mikro¬ organismen und Flüssigkeiten schützen. Hierzu sind besonders hypoallergische mikroporöse Folien geeignet, beispielsweise auf Urethanbasis oder auf Basis polymerer fluorierter Kohlenwasser¬ stoffe.The adhesive dressing according to the invention is suitable for all forms of conventional cannulas for intravenous peripheral use, for example for butterfly or winged cannulas, but also for wingless cannulas and for cannulas with injection valves. Common sweat and oxygen-permeable materials serve as the material for the adhesive dressing, which reliably cover the puncture site and protect against the penetration of microorganisms and liquids. Hypoallergic microporous films are particularly suitable for this purpose, for example based on urethane or based on polymeric fluorinated hydrocarbons.
Vorzugsweise enthält der erfindungsgemäße Haftverband in seinem zentralen Bereich, also über der Einstichstelle der Kanüle, ein transparentes Feld oder Fenster aus einem hierfür üblichen Ma- terial, beispielsweise OpSite , durch welches eine Kontrolle der Einεtichstelle jederzeit möglich ist. Hierdurch können häu¬ fige Verbandswechsel, die nur der Kontrolle dienen, vermieden und die Infektionsgefahr vermindert werden.The adhesive bandage according to the invention preferably contains in its central area, ie above the puncture site of the cannula, a transparent field or window made of a material which is customary for this, for example OpSite, through which the puncture site can be checked at any time. As a result, frequent dressing changes, which are only used for control purposes, can be avoided and the risk of infection reduced.
Die Aussparung im Haftverband, etwa in Form eines ü-förmigen Einschnitts, erleichtert die Fixierung von herkömmlichen Flü¬ gelkanülen, indem die beiden seitlichen Flügel unter die an die Aussparung angrenzenden Haftverbandteile geschoben werden.The cutout in the adhesive dressing, for example in the form of a U-shaped incision, makes it easier to fix conventional wing cannulas by pushing the two side wings under the adhesive dressing parts adjacent to the cutout.
Gemäß einer weiteren Ausführungsform ist der Haftverband im Be¬ reich dieser Aussparung mit einer Halterung für flügellose Ka- nülen ausgerüstet. Diese Halterung hat die Form von klebenden Streifen, die die eingeführte Kanüle oben und unten sandwichar¬ tig umgeben und an die die Aussparung begrenzenden Seiten aus dem mikroporösen Material fixieren. Diese klebenden Haftstrei¬ fen springen von beiden Seiten der die Aussparung begrenzenden Haftverbandteile hervor und sind auf einander zugewandten Sei¬ ten klebend beschichtet. Sie sollen lang genug sein, daß sie von der Seite des Haftverbandes aus, von der sie ausgehen, über die Kanüle und Aussparung hinaus die gegenüberliegende Seite des Haftverbandes erreichen und dort klebend fixiert werden können. Die Halterung gewährleistet eine feste Verbindung der Kanüle mit den beiden Seiten des Haftverbandes, die an die Aus¬ sparung angrenzen. Im allgemeinen ist im Bereich der Aussparung ein Paar einander gegenüberliegender Haftstreifen vorhanden, es können aber auch zwei oder mehrere Haftstreifenpaare vorhanden sein.According to a further embodiment, the adhesive dressing in the area of this recess is provided with a holder for wingless casings. equipped. This holder has the form of adhesive strips which sandwich the inserted cannula at the top and bottom and fix it to the sides of the microporous material delimiting the recess. These adhesive adhesive strips protrude from both sides of the adhesive dressing parts delimiting the cutout and are adhesively coated on mutually facing sides. They should be long enough that they can reach the opposite side of the adhesive dressing from the side of the adhesive dressing from which they originate, beyond the cannula and recess, and can be fixed there by adhesive. The holder ensures a firm connection of the cannula to the two sides of the adhesive dressing, which adjoin the recess. In general, a pair of opposing adhesive strips is present in the region of the cutout, but two or more pairs of adhesive strips can also be present.
