摘要:
The invention provides an ostomy bag assembly comprising outer (2) and inner (4) bags secured to one side of a flange; wherein: the flange (6) comprises a polymeric backing film (8) and a layer of bioadhesive (10) for securing the ostomy bag assembly to the body of a patient; the outer bag is detachably bonded to a first attachment zone (14) on the polymeric backing film of the flange by means of an annular bonding element (22) which is interposed between the outer bag and the first attachment zone; the inner bag is secured to a second attachment zone on the polymeric backing film of the flange; the annular bonding element is formed from a multilayer polymeric material comprising first and second ethylene vinyl acetate layers and a polymeric support layer interposed therebetween; and the first ethylene vinyl acetate layer has a coating of an ethylene vinyl acetate copolymer adhesive thereon.

[Problem] To provide a water-degradable sheet capable of preventing, through biodegradation, drainage apparatuses such as septic tanks from clogging and capable of achieving both water resistance and water solubility, and a pouch for an excretion receptacle comprised of the same. [Means for Solution] A water-degradable sheet capable of dissolving in water when dipped in water, where the water-degradable sheet contains an enzyme to decompose the water-degradable sheet thereinside and the substrate of the water-degradable sheet comprises a water-degradable paper layer and a water-resistant layer. Preferably, the water-resistant layer comprises a biodegradable substrate.

The invention relates to a biodegradable multilayer film material suitable for use in the manufacture of ostomy/urostomy bags and pouches comprising a gas barrier layer and two outer layers of biodegradable ester-amide copolymers. The new multilayer gas barrier film is 100% biodegradable and has improved softness and quietness characteristics.

The bioabsorbable polymers and compositions of the present invention may be formed into medical devices such as stents that can be crimped onto a catheter system for delivery into a blood vessel. The properties of the bioabsorbable polymers allow for both crimping and expansion of the stent. The crystal properties of the bioabsorbable polymers may change during crimping and/or expansion allowing for improved mechanical properties such as tensile strength and slower degradation kinetics. Typically, bioabsorbable polymers comprise aliphatic polyesters based on lactide backbone such as poly L-lactide, poly D-lactide, poly D,L-lactide, mesolactide, glycolides, lactones, as homopolymers or copolymers, as well as formed in copolymer moieties with co-monomers such as, trimethylene carbonate (TMC) or ε-caprolactone (ECL).
摘要:
Biodegradable composite films comprising a starch containing blended polymeric film and a barrier material coated or laminated to the blended film. The use of such composite films in ostomy pouches and other medical products is described. Also described is an ostomy pouch construction in which an adhesive label is affixed to the pouch so as to reduce the escape of odor from the stomal aperture.
