An ostomy bag for receiving bodily waste comprising;
- an outer protective pouch comprising a laminate material having an outer layer of water-impermeable material and an inner layer of water-soluble material;
- an inner waste-collecting pouch enclosed within the outer protective pouch comprising a laminate material having an outer layer of water-soluble material and an inner layer of water-impermeable material,
- and means defining an orifice to enable bodily waste to enter the inner pouch;
- wherein the outer protective pouch is removeably sealed and configured to be opened following use, without separating the inner and outer pouches to allow water to contact the outer protective pouch's inner layer of water-soluble material and also contact the inner waste-collecting pouch's outer layer of water soluble material so that upon immersion in a toilet bowl, water is capable of entering a gap between the inner and outer pouches to break down the bag and allow it to be fully flushed away without removing the inner pouch from the outer pouch;
- and both the outer protective pouch and the inner waste-collecting pouch are of a structure which is weakened upon immersion in a toilet bowl to become less buoyant such that the bag can be flushed away.
