The invention relates to an improved insert for eye wash bottles. Eye rinsing bottles ("Eye showers ^11" ) are intended to be used in first aid to remove a foreign substance from the human eye as soon as possible by rinsing with water or, if necessary, a weak acid such as boric acid solution or a weak base such as sodium hydrogen carbonate solution Bottle body made of easily compressible material, generally plastic, with a built-in valve that allows the flow of air when it is re-expanded, and on the other hand an insert consisting of a riser tube with attached eyecup. Bottle and insert are connected by a standard thread, whereby the underside of the eyecup is designed as a cap nut and the bottle neck is designed as a threaded connector.

When the eye of a patient who is on his back must be rinsed with such a known eye wash bottle is located, the screw connection must first be loosened, the riser pipe removed from the eyecup and the screw connection be restored in order to ensure that the contents of the bottle are completely emptied. These Measure is cumbersome and, above all, time-consuming and not readily understandable for an inexperienced person.

For this reason, inserts for eye wash bottles have already been made with a riser pipe near the mussel Has bore, which in "normal use", that is, when spraying upwards, closed by a sliding ring will. This sliding ring must naturally be larger in the inside diameter than the outside diameter of the riser pipe. By When the bottle is squeezed, compressed air passes through the hole in the riser pipe through the annular gap that is created in this way lost. This reduces the flushing effect towards the top.

When this bottle is tilted, the sliding ring releases the hole so that washing liquid flows through this hole.

can flow. This mechanism is relatively complicated and can be prone to failure, especially when the rinsing bottle is the solution contains a solid, which on prolonged standing can crystallize. Metal sliding rings can also corrode.

From DE-OS 30 35 211 is an eye wash bottle with a Use known which has a shell which is connected to a riser pipe, wherein the riser pipe contains a foot piece for weight loading.

The invention is based on the task of helping injured eyes, especially when the patient is immobile, For example, it is trapped and there is not enough space, or lies on its side for other reasons, E.g. in a stable lateral position in the event of unconsciousness. This is then only with the known device of DE-OS 30 35 211 poorly possible if an upward treatment is to be carried out.

The invention relates to an insert for eye wash bottles, which does not have the disadvantages outlined and can be easily manufactured due to its simple structure. According to the invention namely, the riser is arranged displaceably in the union nut, so that after spraying at the bottom, simply pull the riser pipe out of the bottle along its entire length v; i rd, as a result of which it is completely emptied is guaranteed.

The invention therefore relates to an insert for an eyewash bottle, containing an eyecup (1), which with a riser pipe (2) is connected, which is passed through a union nut (3) and has a foot piece at the end, characterized in that the riser pipe (2) is displaceable and the foot piece is used as a locking element (4) that a Slipping of the riser pipe (2) through the union nut (3) prevented.

The invention relates to an insert for algae rinsing bottles, who does not have the disadvantages described and because of them its simple structure can be easily manufactured. Invention device that is, the riser pipe is arranged displaceably in the union nut ^ so that after spraying At the bottom, simply pull the riser pipe out of the bottle over its entire length, which means that it is completely emptied is guaranteed.

Preferred embodiments of the invention are explained in more detail below with reference to the figure:

The connection of the mussel (1) with the riser pipe (2) can be designed as a plug connection, the fluid inlet of the mussel being designed as a hose connector. These two parts can also - depending on the material - be glued or welded or from a single workpiece exist.

The riser pipe (2) is expediently designed to be flexible because then spraying in all directions is possible. This embodiment of the invention is advantageous when the patient is immobile, for example trapped, and there is not enough space, or for other reasons Reasons on the side, e.g. B. in a stable lateral position when unconscious.

The union nut (3) can be a guiding and sealing element (5) included.

The locking element (Ό, which prevents the riser pipe (2) prevented by the union nut (3), is expediently designed so that it is easily passed through the bottle neck as this makes it easier to fill the bottle. The locking element (4) can in be designed in many ways, for example as a thickening of the riser pipe near the "lower" end, as a pushed-on ring that can be secured with tenons or pins or welded to the riser pipe or is glued, or as a pin which is guided through a bore in the riser pipe.

The end of the riser pipe can contain a valve in the usual way, which prevents the liquid level from turning back prevented when "pumping". This valve is not shown in "" the figure.

The mussel (1) usually contains an outlet, which can be designed in a known manner as a hose connector can and is not shown in the figure.

Of course, the length of the riser pipe (2) is matched to the length of the bottle (6), so with the normal Using the eyewash bottle (syringes pointing upwards) an extensive emptying is possible. The usual eye wash bottles contain - as mentioned above - a valve which is not shown in the figure.

If the riser pipe is used for an eye wash bottle (2) is slidably guided through the union nut (3), the bottle can also be tilted down by pulling it out of the riser pipe can be easily emptied along the entire length.
