Description
Einlage zur Applikation von Medikamenten am Auge Die neue Einlage ermöglicht die Applikation von Medikamenten am Auge auf einfache und wirkungsvolle Weise. Insert for applying medication to the eye The new insert enables the application of drugs to the eye in a simple and effective way Way.
Bis heute erfolgt die Applikation von Medikamenten am Auge nach altbekannten Methoden, nämlich durch Eintropfen von flüssigen Stoffen, durch Spülung mit Hilfe eines besonders geformten Bechers, durch Auflegen eines mit dem Medikament getränkten Läppchens oder durch Einstreichen von Salbe. Beim Eintropfen von Medikamenten muß der Patient eine liegende Haltung einnehmen oder den Kopf zurücklegen, wobei die Tropfen meist durch eine Hilfsperson gegeben werden müssen. Beim Schließen der Augenlider und unter der Spülwirkung der vermehrten Tränenbildung wird die eingeträufelte Lösung rasch aus der Augenhöhle verdrängt und so die Wirkung des Medikamentes stark vermindert, und sie hört nach kurzer Zeit ganz auf. Auch beim Spülen mit einem Augenbecher ist die Einwirkungszeit relativ kurz. To this day, the application of drugs to the eye is based on well-known methods Methods, namely by dripping in liquid substances, by rinsing with the help a specially shaped cup, by placing one soaked with the medication Rag or by spreading ointment. Must be used when dripping medication the patient assume a lying position or tilt his head back, with the Drops usually have to be given by a helper. When closing the eyelids and under the flushing action of increased tear formation, the instilled solution becomes quickly displaced from the eye socket and thus greatly reduces the effect of the drug, and it stops completely after a short time. Even when rinsing with an eye cup is the exposure time is relatively short.
Beim Auflegen eines mit dem Medikament getränkten Läppchens kann die Einwirkungszeit ausgedehnt werden, aber die Sicht des betroffenen Auges wird gehindert, und meist ist ein um den Kopf gelegter Überverband erforderlich, so daß der Patient in seiner Bewegungsfreiheit behindert ist.When placing a cloth soaked in the medication, the Exposure time can be extended, but the vision of the affected eye is impaired, and an over-bandage around the head is usually required so that the patient can is restricted in its freedom of movement.
Weiterhin ist vorgeschlagen worden, sogenannte Kontaktschalen, wie sie zur optischen Korrektur des Auges in Gebrauch sind, zur Einführung und Festhalten von Augensalben zu verwenden. It has also been proposed, so-called contact shells, such as they are used for optical correction of the eye, for introduction and retention of eye ointments to use.
Dem Erfindungsgegenstand liegt der Gedanke zugrunde, das zur Anwendung zu bringende Medikament zusammen mit einem Medikamententräger vorzufabrizieren und dabei in eine dem Auge entsprechende Form zu bringen, welche die jederzeitige Verwendung ohne umständliche Einzelvorbereitung und in einer vorher festgelegten Dosierung gestattet. The subject of the invention is based on the idea that to apply to prefabricate the drug to be brought together with a drug carrier and to bring it into a form appropriate to the eye, which can be used at any time without cumbersome individual preparation and in a predetermined dosage allowed.
Bei einer Augeneinlage als Medikamententräger in Form von dem Augapfel angepaßten Haftschalen aus in Wasser quellbarem Material wird erfindungsgemäß in das Material der Haftschale ein unter Einwirkung der Tränenflüssigkeit durch Diffusion allmählich herauslösbares Medikament eingelagert. Dabei kann die Augeneinlage so ausgebildet sein, daß sie aus mehrschichtigem Material besteht und daß mindestens eine Schicht in Wasser quellbar ist. Die Augeneinlage hat nach Art der bekannten Haftgläser also die Form eines der Gestalt des Augapfels angepaßten Kugelabschnitts (Abb. 1). Sie kann auch bei sonst gleicher Ausbildung mit einem Ausschnitt versehen sein, so daß sie einen Ring darstellt, welcher beim Gebrauch die Linsenpartie des Auges frei läßt (Abb. 2). With an eye insert as a medicament carrier in the form of the eyeball adapted adhesive shells made of material swellable in water is according to the invention in the material of the adhesive shell under the action of the tear fluid through diffusion gradually releasable drug stored. The eye insert can be like this be designed that it consists of multilayer material and that at least one layer is swellable in water. The eye pad has been made in the manner of the well-known Adhesive glasses thus have the shape of a spherical segment adapted to the shape of the eyeball (Fig. 1). It can also be provided with a cutout with otherwise the same training be, so that it represents a ring which, when in use, the lens part of the Eyes free (Fig. 2).
Durch die Augeneinlage gemäß der Erfindung wird erreicht, daß das Medikament unmittelbar an den gewünschten Ort der Einwirkung herangebracht und überdies eine Speicherung desselben erzielt wird, welche über Stunden anhalten kann. Durch die anhaltende Vermengung des freigegebenen Medikaments mit der Tränenflüssigkeit wird der Wirkungsbereich mit Sicherheit auf Cornea, Skera und Conjuktiva des Augapfels, die Innenfläche der Augenlider und entsprechende Drüsen, sowie Kanäle des Tränenapparates ausgedehnt. Die Augeneinlage wird nach Benetzung mit Wasser nach Art der bekannten Haftgläser in das Auge eingesetzt und nach Gebrauch wieder entfernt. Es kann auch ein Material verwendet werden, welches sich unter der Einwirkung der Tränenflüssigkeit auflöst oder so viel an Standfestigkeit verliert, daß sich die Einlage nach der gewünschten Einwirkungszeit von selbst aus dem Auge herauslöst. With the eye insert according to the invention achieved that Drug brought directly to the desired place of action and moreover a storage of the same is achieved, which can last for hours. By the continued mixing of the released drug with the tear fluid the area of action is definitely on the cornea, scera and conjunctiva of the eyeball, the inner surface of the eyelids and corresponding glands, as well as canals of the lacrimal apparatus extended. The eye insert is after wetting with water in the manner of the known Adhesive glasses inserted into the eye and removed again after use. It can also a material can be used which is exposed to the action of tear fluid dissolves or loses so much stability that the insert after the the desired exposure time out of the eye by itself.
