DE2057630A1 - Disposable dropping dispenser - for only use for eye, nose or ear flu - Google Patents

Abstract

The flexible plastic dispenser consists of a container section and a dosing chamber. The container section has a similar volume of air to that of fluid and is connected to the dosing chamber through a constricted point.

Description

Single-use containers filled with drugs. The invention relates to containers made of elastic plastic material containing a liquid medicinal preparation filled and intended for single use.

Liquid medicinal preparations for use on the eye, in the ear or Intended in the nose, are predominantly in glass or plastic bottles with screwed on Pipette put on the market. These contain a multiple of the single dose; therefore, in the course of repeated sampling, e.g. when treating a cold, microbial contamination or contamination of the bottle contents caused by secretions very easily enter. Unsightly, flaky particles develop in the liquid, and reinfection of the patient is possible in the event of bacterial contamination.

These dangers can be caused by containers filled with drugs single use, such containers are already known, but they have some disadvantages. Either a cap must be removed to open it (Belg, Pat, 738 039) The upper tapered part of the container is to be passed through (Brit. Pat. 832 056). The contents of the container can then only be dripped. At the Sch @ upfenbohandlung E.g. the patient has to put his head in the nails.

It has now been found that these disadvantages can be avoided if you use a container which is closed on the whole side and which consists of a container part (i) and a metering chamber (2), which are connected through a constriction (3) are connected. The container part (1) contains next to your liquid volume roughly the same volume of air.

The container according to the invention makes it possible in normal posture a precisely measured dose after piercing the container tip z.13. in the nose inject. It is also advantageous that with simultaneous therapy on the nose and Eye for the eye always a sterile solution by opening a new container can be used. This prerequisite is missing in the currently usual use the pipette bottle.

For use on eyes, ears and other parts of the body can be used for downwards pointing metering chamber (2) can also be dripped. Besides the advantage of the larger Hygiene is more convenient to use when treating a cold than when handling it with the known containers or the dropper pipette.

The invention relates to a drug preparation with a liquid filled container for single use made of elastic plastic material, thereby characterized in that or consists of a container part (1) and a metering chamber (2), wherein the container part (1) has an air volume of approximately the same size in addition to the volume of liquid and is connected to the metering chamber (2) by a constriction (3).

The preferably lens-shaped flattened container (1) can be rectangular, triangular, pear-shaped or round and through protuberances (1) on the dosing chamber (2) facing away from the side should be expanded cylindrical or bubble-shaped. He can go to Turn the dosing canister (2) into a cannula shape.

The shape of the metering chamber (2) is preferably cylindrical.

Of course, the chamber (2) can also be different, e.g.

be spherical or egg-shaped. Size, lung and wall thickness the dosing chamber (2) are provided by the smallest amount of solution provided for Should apply, determined.

To pierce the dosing chamber tip, one with a Needle (5) fitted cap '(6) are added, the dimensions of the cap (6) is matched to the dimensions of the dosing chamber (2) and the needle (5) sticks located in the inner center of the cap (6).

With a filling of 0.1-1 ml, the container according to the invention has preferably a total length between 40-50 mm, the metering chamber (2) is at an outer diameter of about 4 - 6 mm 10 - 20 mm long and the container part (1) 14 - 1G mm wide and 5 - 10 mm thick. The total volume is accordingly about 0.2 - 2 ml.

The plastic material used is elastic, in particular transparent and physiologically flawless qualities, especially high-pressure polyethylene, Polypropylene or polyvinyl chloride. The containers can be sprayed or blown getting produced. They are preferably formed into several in one operation, filled and sealed. Of course, there is also a discontinuous production possible.

To apply the drug preparation, a centrifugal movement the resistance of the constriction (3) is overcome and the metering chamber (2) is filled. To the Checking the exact filling of the dosing chamber (2), it is advantageous if the Container, especially the metering chamber, is transparent.

After the dosing chamber tip has been pierced, the filled dose of solution with the metering chamber (2) pointing upwards by pressing the container part together (1) with the thumb and forefinger, i.e. by compressing the ones enclosed in the container Air to be squirted out. The rest of the solution supply remains in the dead spaces (e.g. the spout (4)) of the container specially shaped for this purpose. If necessary, the dosing chamber (2) can be filled again by turning and spinning and the liquid can be applied in the same way.

This type of application is particularly suitable for the nose.

Several containers, e.g. 3, 5 or 10 pieces, can be easily torn off Connecting webs (7) be connected to one another, forming a strip. A thin spot (8) or a perforation can tear off the individual objects enable from the strip. Without having to deal with the relatively expensive, commonly used Having to strain the pipette bottle, the patient can use one or two objects as a Pocket supplies are carried.
