Abstract
In a reusable collecting bag such as a stoma bag (1) having a narrowed discharge portion (8) including a slit-like discharge opening in the vicinity of its distal end the discharge portion (8) is brought from an open position for emptying the bag through the discharge opening (9) and a closed position of use by folding and unfolding the discharge portion (8) about at least one folding line (24) transverse to the longitudinal direction of the discharge portion (8). To avoid or reduce faecal contamination of the discharge portion (8) in connection with emptying of the bag a series (16, 18) of sequentially peelable stacked protective members (17, 19) is applied to each of two surface sections of the discharge portion (8) adjacent the discharge opening (9).
Claims11
A reusable collecting bag for human body wastes comprising a bag member (1,101,201) formed by two film blanks (2,3;
- 102,103;
- 202,203) with joined edges, an inlet opening (5,105,205) provided in one (3,103,203) of said film blanks, connecting elements (6,106,206) surrounding said inlet opening for connection of the bag to a body orifice, a narrowed, elongated discharge portion (8,108,208) starting at a proximal end at a distance from the inlet opening (5,105,205) and extending between two end sections (2a,3a;
- 102a,103a;
- 202a,203a) of said film blanks to a distal end, a discharge opening (9,109,209) formed in said discharge portion (8,108,208) in the vicinity of said distal end, said discharge portion (8,108,208) being foldable and unfoldable by at least one folding along a folding line (24,112) transverse to the longitudinal direction of the discharge portion between said distal and proximal ends to bring the discharge portion from an open unfolded condition to a closed folded condition and vice versa, and a locking means (10-13;
- 119,120, 112) for locking the discharge portion in said closed folded condition thereof, characterized in that a series (16,18;
- 117,118;
- 216,218) of stacked, sequentially peelable adhesive protective members (17,19) is applied to each of two surface sections of the discharge portion (8,108,208) at either side of the discharge opening (9,109,209).
A reusable collecting bag as claimed in any of the preceding claims, characterized in that the locking means comprises an adhesive layer (124) applied to at least one (120) of two contact surfaces (119, 120) intended to be brought into contact with each other upon folding of the discharge portion (208) towards the closed position.
A reusable collection bag as claimed in any of the preceding claims, characterized in that the protective members (17,19) in each of said series (16,18) are formed as strip members applied to said surface section to extend transverse to the longitudinal direction of the discharge portion (8).
A reusable collecting bag as claimed in any of the preceding clams, characterized in that each of said series (16,18) comprises from 2 to 8 of said stacked protective members (17,19).
A reusable collecting bag as claimed in any of the preceding claims, characterized in that said series of stacked peelable protective members are applied to resilient sealing plates connected with said surface sections of the discharge portion.
A reusable collecting bag as claimed in any of the preceding claims, characterized in that the protective strip or tape members are made from materials, which are water soluble or easily degradable.
