"Device for storage and administration
liquid tube feeding "

The invention is directed to a storage device ί

and administering liquid tube feeding with a supply f holder and a removal device detachably connected to this * tion. I.

So far, this has been the procedure for the administration of tube feeding | been that reservoirs were in the application used, the}; were intended to be used for other purposes, and indeed proportionate | , moderately complex infusion bottles. Relatively complicated puncturing devices were used for removal. In addition, it is * also possible to feed the tube from a dry substance
to be mixed and in specially adapted containers for the dispensing
to decant. The known arrangements are therefore disadvantageous because they either involve a relatively high effort
take up material or time and effort for handling,
especially when decanting the sterility of the

The stringent requirements to be imposed on liquids are not easily met are fulfilled.

The object of the invention is to overcome the disadvantages of the previously known arrangements to avoid and to create a device in which the facilities for the storage and administration of Tube feeding are coordinated from the outset in such a way that an extremely cost-effective, time-saving and hygienic application is made possible by tube feeding.

This goal is achieved in the case of a device as described in the introduction / named type in which the storage container is designed as a disposable bottle with "a crown cork-like cap, and the Removal device has a similar use cap which can be exchanged for the closure cap and in which a ventilation nozzle and an outflow nozzle are arranged. By using Inexpensive one-way bottles made of glass or plastic, which not only facilitate the transport and storage of the nutrient solution, but also serve as a storage container during administration, a considerable cost saving is achieved because only one Bottle needs to be made sterile and this after use can be thrown away. The removal device, the use cap easily and quickly instead of the cap on the Bottle can be put on, like the other, known parts of the removal device can be inexpensive made of plastic getting produced. The bottle contents are except for the only

short replacement process of the caps hygienically perfectly protected.

In a further embodiment of the invention, the bent edge of the usage cap has a circumferential, bead-like edge on the inside Head start. This projection, which is required in the manufacture of the usage cap without an additional operation make is formed, ensures a high level of operational safety of the entire arrangement, since it is also when ctie the nutrient solution receiving bottle in the state of use with the opening is hung down, ensures a secure hold of the usage cap on this opening.

The ventilation nozzle protrudes outwards and is particularly advantageous inside over the cover part of the usage cap. This makes it possible, as provided according to a further feature of the invention is, on the inwardly protruding part of the ventilation nozzle, a ventilation pipe reaching close to the bottom of the disposable bottle and furthermore, according to the invention, a ventilation hose is plugged onto the outwardly protruding part of the ventilation nozzle is. In the state of use, i.e. with the opening after storage bottle hung at the bottom, then the ventilation nozzle protrudes, which is connected to the ventilation hose, above the liquid level and thus enables the nutrient solution to flow out unhindered.

It turns out to be beneficial that the free end of the ventilation

hose is provided with a coupling device for placing a pressure ball. In this way, overpressure can be built up above the level of • liquid in the storage bottle and thus ψ the outflow of the nutrient solution can be accelerated.

t
ti * Further features, details and advantages of the invention emerge from the following description of a preferred embodiment and with reference to the drawing. Show:

Fig. 1 is a perspective view of the storage container applied cap in the dispensing position and FIG. 2 shows a section along the line II-II in FIG. 1.

The use cap 1 according to the invention comprises an approximately flat cover part 2 and a bent edge 3 which is attached to a disposable bottle 4 put on the opening 5 like a crown cork overlaps. To fix it in this position, there is a. curved edge 3 of the use cap 1 formed on the inside, inwardly protruding bead-like projection 6, which is in a corresponding circumferential parallel to the opening on the disposable bottle 4 Slot into place. To make it easier to put on and take off a handle attachment 7 is arranged on the outside of the bent edge 3 of the cap 1 for use.

The cover part 2 of the use cap 1 has a ventilation and an outflow nozzle 8 and 9, respectively. These are advantageously made from the same plastic as the rest of the usage cap 1. The ventilation nozzle 8 extends both inwards and outwards. The outlet nozzle 9, which has a larger one Has inner diameter d than the ventilation nozzle 8, extends only to the outside.

The outflow nozzle 9 is over its entire length from the connecting piece 10 of the lid 11 of a drip chamber 12 penetrates, the inner end 13 of which the opening edge 14 of the outflow nozzle 9 overlaps so that the drip chamber 12 is securely connected to the cap 1 for use. The drip chamber 12 is followed by a Hose line 15 for the tube feeding, which by means of a Roller clamp 16 can be opened and closed.

Il 14 * (

On the inside of the ventilation nozzle 8, an inherently rigid tube 17 is placed, which extends into the area of the bottom of the disposable bottle 4 is enough and thus enables the tube feeding to flow evenly and undisturbed. On the outside of the Ventilation connector 8 is a hose line 18 made of plastic placed, which enables ventilation via a bacteria filter not shown in the drawing. At the end of the ventilation line there is a coupling piece connected to the bacterial filter, to which a pressure ball can be connected.

The application of the device according to the invention takes place in such a way that the closure cap of the disposable bottle 4 reliably closes, removed and immediately placed the use cap 1 with the additional devices connected to it will. The disposable bottle 4 is then brought into the position of use, i.e. hung with the opening 5 facing downwards. In the further The procedure is known per se, the drip chamber 12 for monitoring and setting a defined output quantity of probe liquid and the roller clamp 16 to open and closing or partial closing of the hose 15 connected to the outflow nozzle 9 is used.
