Discharge solidifier and malodour control

Abstract

An ostomy bag insert ( 104 ) comprising a polyacrylate superabsorbent ( 300 ) and a powdered zeolite ( 301 ). The ostomy bag insert is configured to absorb fluids excreted by the body and to control odours resultant from the excreted matter within the ostomy bag ( 100 ). The present zeolite exhibits enhanced odour control.

1 . An ostomy bag insert comprising:
 a polyacrylate superabsorbent; and   a powdered zeolite;   wherein the superabsorbent is coated with the powdered zeolite.   
     
     
         2 . The insert as claimed in  claim 1  wherein the powdered zeolite comprises a particle size equal to or less than 0.15 mm. 
     
     
         3 . The insert as claimed in  claim 1  wherein the zeolite comprises a particle size equal to or less than 0.075 mm. 
     
     
         4 . The insert as claimed in  claim 1  wherein the zeolite comprises a particle size of equal to or less than 0.045 mm. 
     
     
         5 . The insert as claimed in  claim 1  wherein the zeolite is a zeolite blend comprising a hydrophilic zeolite and a hydrophobic zeolite. 
     
     
         6 . The insert as claimed in  claim 5  wherein the hydrophobic zeolite is an ammonium zeolite and the hydrophilic zeolite is a sodium aluminosilicate. 
     
     
         7 . The insert as claimed in  claim 1  wherein the zeolite comprises a surface area of substantially 400 m 2 /g. 
     
     
         8 . The insert as claimed in  claim 1  further comprising powdered activated carbon. 
     
     
         9 . The insert as claimed in  claim 8  wherein a weight % ratio of the activated carbon to the zeolite as part of the insert is in the range 0.01:1 to 0.05:1. 
     
     
         10 . The insert as claimed in  claim 1  wherein the polyacrylate superabsorbent is granular. 
     
     
         11 . The insert as claimed in  claim 1  wherein the superabsorbent comprises sodium or calcium polyacrylate. 
     
     
         12 . The insert as claimed in  claim 1  further comprising a water soluble paper formed as a sachet to house the superabsorbent and the zeolite. 
     
     
         13 . The insert as claimed  claim 1  further comprising a water soluble film to house the superabsorbent and the zeolite. 
     
     
         14 . The insert as claimed in  claim 1  further comprising a gel cap to house the superabsorbent and the zeolite. 
     
     
         15 . The insert as claimed of  claim 1  further comprising a plastic straw or plastic wand to house the superabsorbent and the zeolite. 
     
     
         16 . The insert as claimed in  claim 1  wherein the insert is formed as a soluble tablet. 
     
     
         17 . The insert as claimed in  claim 1  comprising 1,000 mg to 10,000 mg of polyacrylate superabsorbent. 
     
     
         18 . The insert as claimed in  claim 1  comprising 25 mg to 5,000 mg of the powdered zeolite. 
     
     
         19 . The insert as claimed in  claim 1  comprising a metallic salt impregnated zeolite. 
     
     
         20 . An ostomy bag comprising an insert as claimed in  claim 1 .
