The present inve~tion relat~s to an in~u6ion bag having at lea~t one collapsible chamber that hold~ a liquid, and a non~
collapsi~le outlet tube that i~ connect~d to the chamber and with a breathex devica (appendix to Patent AE~plication 38 26 456).
Infusion bags of the typ~ de~cribed above ar~ u~ed in medicine in order to supply pati~nt~ with liquid~, f.`or example, for nutritional purpose~O Since the liquid has to ba admini~ter~d to ths patienk in pr~æaribed volumes, it i8 nece~ary ko check the volume of liquid 90 infused con~tantly, or to determine this, if the total contents of the bag are not to be admini~tered, but only a portion th~reo~. In particular, when a patient is being ~ed artificially, it iæ de~irable that the contants of the bag be administered in individual portion~ over a longer pQriod o~ time.
In order that th~ medical p~rsonnel can ch~ck, on the one hand, whether or not the desired quantity of li~uid has been admini~tered to the patient, and, on th~ other hand, can de~ermine whether or not ~u~ficient liquid remains in the bag, it ;
i6 desirable that the ~uantity o~ uid that has been administered ran he d~termined in a suitable mannex.
I~ is:known ~rom the priox art that ~low measuxement systems can . ;
be pro~ided in th2 tubes so as to permit preclG~ ~etermination of :`
the volume o~ uid that ha~ b~en adminietered in this way.
This procedure entalls the disadvantag~ that measurement ~ystems of this kind are aompllax and c08tly and have t~ be u~ed by , ':

per~onnel skilled in the art. In particular in the case o~ less highly train~d per onnel and~or in countriss of the third world, this solution is impractical.
A ~urther possibility o~ datermining the volume of liquid that has been admini~tered iB to provid~ a calibrated tube with a fixed flow rate and then determine the necessary periods o~ time that are required in each instance. The di~advantage in this is that th~ out~low time mu~t be praci~ely monitored.
It is the task o~ the present invention to cre~e a collapsible bag of the typs described in the introduction h~r~to, which, being of ~imple construation and being cheap to produce permits ~u~iciently preai~e determination o~ the quantity of li~uid that has been administeredO

According to the present invention, thi~ task ha~ been solved in that a soale is attaahed to a tran~parent side o~ the bag.
The bag according to the present invention is characterized by a numbex of considerable advantages. Using the scal~ that is attached to the 8ide o~ the bag, it is po sible to dat~rmin~, either vi~ually or wikh the help o~ a det~ctor ~yst~m, by comparison the level o~ ths li~uid withln the container.

A furthex and important advantage o~ the bag according to the present invention is that the type o~ scale can be matched in a particularly simple mannar to the requirementR in ~ach case.
Thus, for example~ it i~ not ne~essary to set up the scale in volume unit~ of the usual dimensions; rather, the scale can be divided inko hourly or daily rations or other units. In this conrleation, it i~ also advantageous that the ~cale do~ n~t need to be linear, rather, the simple type and configuratio~ of the 6cale makes it po~sible to match khi~ in a particularly ~imple manner to the particular bag size or bag shape.
Since the bag according to the present invention i~ fitted with a breather ~evic~, a~ter removal o~ a prescribed ~uantity o~
liquid, the remaining v~lume o~ the chamber ~ills with air, i.e., an open ~y~tem results, thi~ being ~imilar to the system used in an in~u~ion bottl~. Thi~ av~ids ~he side~ o~ the bag being pres~ed against :~ach other and thereby ~alsi~ying the reading.

In a furth~r, extremely advantageou~, con~iguration o~ the present invention, the br~ather device includes an essentially rigid brsakable tube that is open to the atmosphere and, when the bag is closed, i~ clo~ed o~f relative to the chamber. The breather device can thus be produced together with the bag; it ~orms a component part of tha bag system ~nd can be broken when the bag is used, which is to say, the breather device can be opened. In a bag that is con~igured in this wayl no additional individual parts are requir~d; on the contrary, a system that is ready for use is ~ormed ther~by. The break-o~ configuration of the tube entails the advantage that no other manipulation of the sy tem, by which the bag could be damaged, are needed. The broken off end o~ the tube remains in the chamber o~ the bag and does not interfere with the removal process.
:
In order that the tub~ can be broken of~ preci~ely, it is advantageous i~ the tube is provided with a nominal break point.
In an alternative configuration o~ th bag, it i~ foresQen that ths breat.her device includes an e~santially rigid tube in which there is a plug or closing element that can be panetrated by means of a cannula~ Thus, the bag c~n b~ connected to tha atmosphere by means o~ a commarcially available cannula and, given a suitable configuxation o~ the plug~ it i~ pos~ible to ~lose the bag onas again by withdrawing tha cannula an~ ~hus interrupt the removal process ~or a longar period o~ time. In . .

addition, khis configuxation makes it possible to introduce other additive~ into the chamber of the bag by means of the cannula in order that said additives can be mixad with the liquid within the bag. Furthermore, if the removal process is to be interrupted, it is possible to express the re~idual air contained within the bag from the chamber in order to prevent the liquid being changed as a re6ult o~ chemical reactions with the air.
The plug is preferably of ~ilicon or a similar material.
It is particularly advantageous if the cannula ~an be insertad so as to b~ a ~ight fit in the tube and/or incorporates at least one suitable sealing ~ection in order to ensure adequate sealing in the event of a permanant penetration of the plug and, on the other hand, to anchor the cannula mechanically within the pipe.
:' In order to prevent the ingress of b~cteria into the chamber of the bag~ lt is preferred that ~he breather device be fitted with a~hydrophobio bacterial filter.

It is pa~rticularly advantagaous: that the ba~ can be ~f rectangular ~hape; however, it i~ al~o po~ibl~ to configure the bag ln any ~ther shape. Furthermor~, according to tha present invention, it ~ al~o po~sible ~Q form th~ bag as a multi-chamber bag, wh~n th- variou~ ohambers can be connected to each other.

I~ this is done, the scale can be provided on on~ chamber or a plurality o~ chambers.
In order to ensure that the bag empties evenly, it i~
advantageou~ that the bag b~ pravided with a centrally located suspension point and~or that the outlet tub~ be located centrally at the lower end of the bag. This prevents any tilting or tipping of the bag and any undesired deformation of th~ bag.
