Abstract: The device for applying medicinal preparation in the form of powdered lyophilizate (3) to eyes of patients, comprises an applicator (1) with a holder (10) for receiving a container (2) containing the medicinal preparation, an adapter (12) communicating with the holder, where the adapter is placed in the surrounding of an eye socket of the patient with its side turned away from the holder and the medicinal preparation to be applied is detached from the container, and a compressed air-source, which is connected with the applicator over an air inlet pipe. The device for applying medicinal preparation in the form of powdered lyophilizate (3) to eyes of patients, comprises an applicator (1) with a holder (10) for receiving a container (2) containing the medicinal preparation, an adapter (12) communicating with the holder, where the adapter is placed in the surrounding of an eye socket of the patient with its side turned away from the holder and the medicinal preparation to be applied is detached from the container, and a compressed air-source, which is connected with the applicator over an air inlet pipe. The container contains a single dose of the medicinal preparation and is openable in the position incorporated in the holder. The medicinal preparation is conveyed from the container placed in the holder in the direction of the adapter under the use of gravity. The applicator comprises a downpipe, which connects the holder with the adapter and in which the medicinal preparation is enterable from the container incorporated in the holder. The downpipe is vertically aligned, where the upperside of the holder and the underside of the adapter are connected to the downpipe. The adapter is coaxially aligned to the downpipe. The air inlet pipe flows into a collection chamber within the applicator, for medicinal preparation removed from the container, and guides a discharge pipe from the collection chamber to the adapter. A compressed air bottle is provided as the compressed air-source. The holder comprises a hole for conveying the medicinal preparation removed from the container. The holder is equipped with positioning aids for accurate positioning of the container over the hole. The container is formed as a blister with a cup receiving the medicinal preparation, where the opening of the cup is covered by a peelable sealing foil. The sealing foil is fastened on a sealing edge of the blister over an adhesive layer and an adhesion-mediated coating is provided on the adhesive layer in the region of the opening of the cup. The sealing foil is applied twice in the region of the opening of the cup and comprises a flag-like projection serving as a gripping- or information-element above the blister. The opening of the eyelid is effected by the ends of the adapter, which turned away from the holder, at a position attached to the surrounding of the eye socket. The powdered lyophilizate of the medicinal preparation comprises spheroidal lyophilizate of same size with a diameter of individual particle of 100-300 mu m.
