Device for administering liquid eye treatment agents in the form of a lever

The invention relates to a device for administering optionally dosed amounts of liquid treatment agents for ophialmological purposes in the form of a mist from an atomizer with an am. Outlet end of the interior arranged valve

Pharmaceutical liquid compositions for treating eye diseases have heretofore been unique with With the help of a dropper (instillation directly into the eye) or with the help of an eye bath (in a for

a glass or plastic jar provided for an eye bath ') administered. In particular, these two modes of administration have the following disadvantages: they are not, antiseptic; they are sometimes painful; "They can lead to accidents; they do not allow precise dosing of the. Remedies or treatments

The object of the invention is to create a device for the painless and safe administration of liquid eye treatment agents in the form of mists which avoids the disadvantages outlined above

The device according to the invention comprises a smoke generating device and a plug which is tightly fitted in the upper part of the mist generator, with a conduit arranged therein, which is initially perpendicular from the lower part of the plug and then horizontally through this runs and is provided for the supply of the mist from the mist generating device, and an atomizing device, which is a frustoconical part forming the chamber or space for the mist distribution and a tube inserted through the plug in the plane of the horizontally extending tube and with its outer end is adapted tightly to this tube, wherein

the other end of which is fitted tightly in the apex of the truncated cone;

The device according to the invention contributes to a substantial improvement in the. Administration of treatment agents for ophthalmologic purposes. While, as above described, the use of a dropper can lead to accidents if moved carelessly, and when using an eye bath the eye in contact with; Impurities or dirt can get in, these will be Disadvantages when using the device according to the invention are completely avoided »

When using the device g ^ according to the invention ■ the eye is bathed in a mist that comes out of the bottle under pressure, which is what a pharmaceutical Contains laboratory made remedies, being

all necessary hygienic! conditions guaranteed »Here there is neither a difference between the product manufactured by the laboratory and its application to the eye Handle or any instrument required. The device of the invention ensures an excellent Protection of ophthalmic medicaments when administered, when using the device according to the invention

a liquid eye medicine in the form of ITeTDeI (which is inexpedient is also referred to as aerosol) administered; which * is generated by a valve at the outlet of a container, in the interior of which the liquid is driven by a completely harmless, inert gas such as nitrogen will.

The device is explained in more detail below with reference to the drawing »

As can be seen from the figure, the door direction according to the invention essentially comprises two main dividers 1, a plug 1 made of semi-rigid plastic, which is tightly fitted into the upper part of a fog-generating device. In its upper part, the plug 1 contains a line that runs vertically (part 2) and then horizontally (part 5} and allows the febula to escape into the actual atomizer; - 2, a distributor also made of semi-rigid plastic, which in turn from a) a truncated cone-shaped part 4, which forms the secondary diffusion chamber, and b) a tube 5, the outer end of which is tightly adapted to the outlet of the horizontal line 3 of the stopper 1, and that on the opposite side in the apex of the truncated cone 4 is fitted. Of the

_ 5 -

The diameter of the tube 5 is in the part that enters the truncated cone 4 penetrates, very little, so that a strongly driven forward atomization of the liquid in the atomizer is ensured.

According to; According to the invention, the atomizer can also have a somewhat different shape; so can the circular Base area of the truncated cone, which is open at the wide end; by be an elliptical base .ersetzt.

That for making the different parts of the gate direction plastic material used, preferably consists of high-pressure polyethylene (grade 2.); it can, however other materials are also used for this purpose.

The pellet solution contained in a container is expelled or atomized by an inert gas, for which nitrogen is preferably used.

By the device according to the invention, the solution containing the medicinal product is in the form of a mist from the outlet of the Container in the atomizer by means of the tube with low Diameter straightened "

If desired, inside the tab or the container a dosing device be attached, whereby the administration of a precisely dosed medicinal or

Inside the hash or the container can be an exact Amount of treatment agent to be administered at each pressure.

6 »When using the device according to the invention isjfc the help of a second person is not required »
