Abstract: ABSTRACT OF THE DISCLOSURE           An arrangement for the reduction of the stomach reservoir through an intragastrally-applicable cushion formed of a gastric juice-compatible material, which is detachably connected with a perorally-introduceable appli-cator, which can be filled through the applicator with a gastric tract-and intestinal tract-compatible fluid, and which includes an opening closeable valve-like by detachment of the applicator from the cushion during the extraction of the applicator. When the positioned cushion becomes unsealed then, in a simple manner, it can discharge through the intestine with the feces.  There is no danger that the cushion will remain suspended at a restricted location within the intestinal tract (for example, at the transition from the small to the large intestine, the ileosocal valve).          When a filling with water is employed, then the cushion is located proximate the pylorus, whereas with an air filling it is located proximate the fundus, especially when the stomach is filled.

Abstract: BAG STAND CONTAINER            ABSTRACT          A free standing frame and lid assembly has been developed for supporting garbage bags during filling which offers special advantages of rigidity, ease of bag attachment and removal, cleanliness and simplicity compared to other types of stands or containers.  Although it is known that the principle of a lid and frame assembly for supporting an open plastic bag is in use, attached to cupboard doors or walls, etc., the proposed invention requires no such support during use and therefore can be transported about during filling.  This is an advantage when cleaning up open areas. In addition, the simplicity of the frame design and clip-on lid attachment as compared to other methods not only permits low cost to manufacture, but also provides a garbage container which can be easily washed and kept clean.  This advantage of a clean frame and a specially designed clean tight fitting lid could be important for use in hospitals and other institutions.  Finally the ease of attachment and detachment of a filled bag without special clips or of having to lift the bag for removal when filled, are special advantages made possible by the unique combination of a two legged stand supporting a four cornered frame opening designed for a given side of plastic garbage bag.          PURPOSE OF THE INVENTION            The purpose of the invention is to provide a structural frame for supporting the open top of a plastic or fabric bag during filling, and of sliding the filled bag out of the stand without the necessity of lifting the bag.          A second purpose of the invention is to provide a device for handling garbage which is inexpensive to make, light in weight, odourless and sanitary.
