Definitions

  • Such bags are known for example from DE 196 00 530.2.
  • the generic Bags are especially used for the storage and administration of industrially manufactured Nutrient solutions used.
  • the nutrient solutions are applied, for example, via probe systems Patients who are given the usual food intake after an operation Intervention is not possible.
  • a bag with a free flood area between the outer and inner Pouch in the longitudinal direction of the pouch is known from US-A-4381776.
  • the nutrient solutions typically contain substances necessary for the maintenance of life proteins, fats, carbohydrates, minerals, vitamins and Trace elements.
  • a plastic or foil bag offers a nutrient solution compared to the conventional one Glass containers provide much better protection. When emptying the container there is no need to fill up the remaining volume with air, rather it shrinks the bag with its emptying

  • the free flooding area causes the Double component that the fluid substance in the free when opening the inner bag Flooding area and thereby creates a kind of gush, which a rapid rise of the Liquid level in the outer bag along the outer walls of the inner bag guaranteed.
  • the free flooding area therefore creates a kind of "initial surge" that below the lower area of the outer bag from the outer wall of the inner bag keeps away and thus a largely unimpeded rise in the liquid level in the outer bag ensures.
  • At least the one bag edge is the outer Bag formed as a rounded edge, so that the free flood area along this Bag edge enlarged due to the rounded design.
  • the converging ones Bag edges therefore do not have to be sharp-edged, but can be as rounded edges still the free flooding area between inner and outer bag enlarge and favor the formation of the "initial surge".
  • the rounded bag edge is also a sight glass with scale, in order to be able to control the nature and level of the fluid substance.
  • the inner bag expediently becomes eccentric in the outer bag fixed.
  • the eccentric fixation happens so that the inner bag is related to the Position of use of the double bag is arranged in the outer bag shifted upwards.
