Definitions

  • the invention relates to a bag with at least one collapsible chamber for receiving a liquid with a non-collapsible drain hose connected to the chamber and with a ventilation device connecting the chamber to the environment (addendum to patent application 38 26 456).
  • Bags of the type described in the introduction are used in the medical field to supply liquids to patients, for example for nutritional purposes. Since the liquid has to be supplied to the patient in predetermined volume quantities, there is a need to check or determine the volume quantity supplied whenever it is not intended to administer the entire contents of the bag, but only part of the same. In the case of artificial feeding of a patient in particular, it is desirable to supply the patient with the contents of the bag in individual subsets over a longer period of time. So that the medical staff can check whether the patient has been supplied with the desired amount of liquid and can also determine whether there is still a sufficient amount of liquid in the bag, it is desirable to determine the amount of liquid dispensed in a suitable manner.
  • Another possibility of determining the volume of liquid dispensed is to provide a calibrated hose with a fixed flow rate and to determine the time intervals required in each case.
  • the resultant disadvantage is that the outflow time must be monitored precisely.
  • the invention has for its object to provide a collapsible bag of the type mentioned, which allows a sufficiently exact determination of the amount of liquid dispensed with a simple structure and inexpensive to manufacture.
  • the object is achieved in that a scale is attached to a transparent wall of the bag.
  • the bag according to the invention is characterized by a number of considerable advantages.
  • the scaling attached to the wall of the bag makes it possible to determine optically or with the aid of a detector system by comparison the level of the liquid level in the container.
  • the scaling provided according to the invention can be precisely calibrated in a particularly simple manner, since it is known in what way the bag deforms during its gradual emptying. With the appropriate suspension or storage of the bag, the same liquid level will always be obtained with the same amount of liquid removed.
  • Another major advantage of the bag is that the type of scaling can be adapted to the particular requirements in a particularly simple manner. It is therefore not necessary, for example, to design the scaling in volume units of customary dimensions. or daily rations or similar Units. It is also favorable that the scaling is not linear rather, the simple type and design of the scaling enables it to be adapted to the respective bag sizes or bag shapes in a particularly simple manner.
  • the bag according to the invention is provided with a ventilation device, the chamber volume remaining after the removal of a predetermined amount of liquid is filled with air, i.e. an open system is created, which is similar to the system of an infusion bottle. This prevents the bag walls from being pressed against one another and thus falsifying the display. The spacing of the bag walls from one another is thus predetermined by the volume of liquid in the chamber, a subsequent compression or contraction of a bag by the air pressure acting from the outside is excluded.
  • the ventilation device comprises a substantially rigid, breakable tube which is open to the environment and is closed to the chamber when the bag is closed.
  • the venting device can thus be manufactured together with the bag, it forms part of the bag system and can be broken open when the bag is used, i.e. be opened. With this design of the bag, no additional individual parts are required, rather a ready-to-use system is available.
  • the breakable design of the tube has the advantage that no other interventions in the system are required through which the bag could be damaged. The broken end of the tube remains in the chamber of the bag and does not interfere with the removal process.
  • the ventilation device comprises an essentially rigid tube in which a closure element which can be pierced by means of a cannula is arranged.
  • the bag can thus be connected to the environment by means of a commercially available cannula; if the closure element is designed accordingly, there is the possibility of closing the bag again by pulling the cannula and thus interrupting the removal process for a longer period of time.
  • this embodiment offers the possibility of introducing further additives into the chamber of the bag by means of the cannula in order to mix them with the liquid that is in the bag.
  • the closure element is preferably made of silicone or a similar material.
  • the cannula can be inserted tightly into the tube and / or at least has a corresponding sealing attachment in order to ensure a corresponding seal in the event of a permanent severing of the closure element and on the other hand to mechanically anchor the cannula in the tube.
  • the ventilation device is preferably equipped with a hydrophobic bacterial filter.
  • the bag can have a rectangular shape in a particularly advantageous manner, but it is also possible to design the bag in any other configuration. Furthermore, it is also possible according to the invention to design the bag as a multi-chamber bag, the different chambers being able to communicate with one another.
  • the scaling can be provided on one chamber or on several chambers.
  • the bag is provided with a central hanging device and / or the drain hose is located centrally at the lower end of the bag. This prevents tilting or tilting of the bag and undesirable deformations.
  • Fig. 1 shows a side view of a bag 1, which is produced in that two mutually parallel film layers are connected to each other along a sealing line 13, for example welded.
  • the bag preferably consists of a transparent material in order to make the liquid in a chamber 2 appear visible.
  • the bag 1 has at its upper end a suspension device 12 provided with an eyelet, at the lower end of the bag 1 a drain hose 3 is welded, which is open to the chamber 2.
  • a ventilation device 4 is provided, which will be described in detail below.
  • At least one of the side walls of the bag 1 is provided with a scale 5, which is designed, for example, in the form of horizontal, printed lines.
  • the scale 5 can be assigned to a liquid level 14 of a liquid located in the chamber 2, so that it is possible to determine the liquid volume remaining in the bag optically or with the aid of other detectors.
  • the distances between the individual divisions of the scale 5 can be easily adapted to the respective requirements.
  • the ventilation device 4 provided in the exemplary embodiment according to FIG. 1 comprises a rigid tube 6 which is open to the environment and is provided in this opening with a hydrophobic bacterial filter 11 or a similar filter.
  • the end of the tube 1 projecting into the chamber 2 is closed.
  • the tube 6 consists of a breakable material, preferably a predetermined breaking point 7 is provided in order to break the tube 6 at the desired point.
  • the exemplary embodiment shown in FIG. 2 differs from the exemplary embodiment according to FIG. 1 by the design of the ventilation device, the same parts have been provided with the same reference numbers, so that a detailed description of these parts can be dispensed with.
  • the ventilation device 4 comprises a rigid tube 8 which is open both to the environment and to the chamber 2.
  • a closure element 10, for example in the form of a silicone plug, is provided in the lumen of the tube 8.
  • the closure element 10 is pierced by means of a cannula 9 in order to thereby cut through the closure element 10.
  • the cannula 9 can be dimensioned in this way be that it is either inserted into the tube 8 appropriately and prevents lateral escape or penetration of air, but it is also possible to provide the cannula 9 with a smaller thickness so that it can be interrupted during the emptying process from the closure element 10 can be pulled out.
