Abstract
Description
Verfahren und Vorrichtung zur inter mediären Fluidapplikation, insbe sondere für medizinische Anwendungen.Method and device for inter medical fluid application, esp especially for medical applications.
In der Tier- und Humanmedizin be steht häufig das Problem, Flüssig keiten (auch Medikamente) an Gewe bearealen der Körperoberfläche oder des Körperinneren für begrenzte Zeit in definierter Konzentration zur Verfügung zu stellen.In veterinary and human medicine be often the problem is liquid (also medication) on tissue Beareal the surface of the body or of the body for a limited time in a defined concentration for To make available.
Häufig führt die Flüssigkeits applikation durch einfache Spülung zu dem Nachteil, daß große Flüssig keitsmengen wegen des permanenten Abflusses gebraucht werden, und daß entsprechend aufwendige Vorsorge zur Benetzung begrenzter Areale bereit gestellt werden müssen (z. B. Absaug- Vorrichtungen). In begrenzten Anwen dungsbereichen sind auch ober flächliche Verbände bekannt, die als flüssigkeitsgetränkte Verbandstoffe oder Gele eine Benetzung der Ober fläche sicherstellen. Mit den heute bekannten Verfahren sind nur sehr kleine Areale im begrenztem Umfang versorgbar.Often the fluid leads application by simple rinsing to the disadvantage that large liquid quantities due to the permanent Runoff are needed, and that accordingly expensive provision for Ready to wet limited areas must be provided (e.g. suction Devices). In limited applications areas of application are also upper flat associations known as liquid soaked dressings or gels a wetting of the upper ensure area. With today known methods are only very small areas on a limited scale available.
Beispielsweise können größere Wund höhlen nach schweren Verletzungen oder größeren Operationen nicht entsprechend versorgt werden. For example, larger sores cave after serious injuries or major operations be supplied accordingly.
Erfindungsgemäß soll dieses Problem dadurch gelöst werden, daß ein biokompatibles Kunststoffmaterial zum Einsatz gelangt, das eine extrem hohe Aufnahmekapazität an Flüssig keit hat, selber nicht toxisch ist und auch mehrfach mit Flüssigkeit beladen werden kann.This problem is intended according to the invention be solved by a biocompatible plastic material is used, which is an extreme high liquid absorption capacity is not toxic itself and also several times with liquid can be loaded.
Dieses Material soll weiterhin die Eigenschaft haben, im beladenen Zu stand gelartig aufzuquellen und damit auch über normale Saugspül systeme transportierbar sein.This material is said to continue Have property in loaded to stood to swell like a gel and thus also via normal suction rinse systems can be transported.
In einer bevorzugten Ausführungsform besteht dieser Kunststoff aus Polyacrylamid als feinpulverigem Granulat, das die Eigenschaft extrem hoher Flüssigkeitsaufnahme aufweist und gleichzeitig nichttoxisch und biokompatibel ist, auf der anderen Seite ist dieses Material auch nicht dauerhaft beständig, sondern zer setzt sich nach längerer Zeit selbständig in Wasser, Kohlendioxid und Stickstoff, alles wiederum nichttoxische biokompatible Kompo nenten.In a preferred embodiment this plastic is made of Polyacrylamide as a fine powder Granules that have the property extreme has high fluid intake and at the same time non-toxic and is biocompatible on the other This material is not side either permanently stable, but zer sits down after a long time independently in water, carbon dioxide and nitrogen, all in turn non-toxic biocompatible compo nenten.
Die erfindungsgemäße Vorrichtung umfaßt einen Quellbehälter, in dem das sterile Granulat in vorgegebenen Mengenverhältnissen mit dem Fluid, getränkt wird, wobei das Fluid (z. B. physiologische Kochsalzlösung), be stimmte Anästhetika, Antibiotika oder auch Cytostatika enthalten kann. Nach dem Quellvorgang wird das entstandene Gel über eine Sprit zenpumpe an die betreffende Kör perregion bzw. in das Hohlorgan eingebracht und kann am Applika tionsort entsprechend der geplanten Medikation verweilen und im Anschluß daran problemlos über einen normalen Sauger wieder entfernt werden. The device according to the invention includes a source container in which the sterile granules in given Proportions with the fluid, is soaked, the fluid (e.g. physiological saline), be agreed anesthetics, antibiotics or also contain cytostatics can. After the swelling process, it will created gel over a fuel Zen pump to the body in question perregion or into the hollow organ introduced and can on the applica location according to the planned Medication linger and then about it easily over a normal Suction cups are removed again.
Das bevorzugte Ausführungsbeispiel eines derartigen intermediären Flüssigkeitsspeichers ist Polyacryl amid-Granulat, das in der Lage ist, die gespeicherte Flüssigkeit durch Kapillarwirkung an die umgebende Oberfläche abzugeben. Auf diese Weise können z. B. in einfachster Form auch großflächige Verbrennungen dauerhaft mit Flüssigkeit benetzt und von der Luft abgeschlossen werden, wobei der benetzenden Flüssigkeit sowohl Anästhetika als auch Antibiotika beigegeben werden können. Nach Abschluß der Therapie läßt sich diese Gelschicht problem los absaugen.The preferred embodiment of such an intermediate The liquid storage is polyacrylic amide granules that are able to the stored liquid Capillary action on the surrounding Deliver surface. To this Ways can e.g. B. in the simplest Form also extensive burns permanently wetted with liquid and shut off from the air be, the wetting Liquid both anesthetics and antibiotics can also be added can. After completing therapy can this gel layer problem suck off.
In Weiterführung des Erfindungs gedankens wird beim Herstellprozeß bereits das Polyacrylamid mit wasserlöslichen Pharmaka beladen, so daß in der Klinik lediglich noch eine Aufschwemmung mit entweder destilliertem Wasser oder physio logischer Kochsalzlösung zu erfolgen hat und damit eine genaue Dosis- Wirkungssteuerung möglich wird.In continuation of the invention is thought during the manufacturing process already with the polyacrylamide loaded water-soluble pharmaceuticals, so that in the clinic only a deluge with either distilled water or physio logical saline solution and therefore has an exact dose Impact control becomes possible.
Abb. 1 zeigt das Prinzipbild einer einfachen Vorrichtung zur Beladung des Polyacrylamidgranulats mit dem Therapiefluid, wobei das Beladungs gefäß vorzugsweise bereits in Form eines Spritzenzylinders ausgebildet ist, der anschließend lediglich in eine normale Spritzenpumpe nach dem Stand der Technik eingelegt wird. Das sodann entstandene zähflüssige Gel wird über einen sterilen Schlauch an den vorgesehenen Applikationsort gebracht. Fig. 1 shows the basic diagram of a simple device for loading the polyacrylamide granules with the therapy fluid, the loading vessel is preferably already in the form of a syringe barrel, which is then only inserted into a normal syringe pump according to the prior art. The viscous gel that is then formed is brought to the intended application site via a sterile tube.
Wenn es sich um die Applikation in einem halboffenem Hohlorgan handelt, muß gegebenenfalls ein Abwandern des Gels durch Tamponaden verhindert werden. Nach Ende der Behandlung wird das Gel über ein normales Absaugsystem mit Fangflasche abge saugt.When it comes to the application in a semi-open hollow organ, a migration of the Gels prevented by tamponades become. At the end of treatment the gel becomes a normal one Extraction system with catch bottle sucks.
