Commode

Abstract

A commode is provided comprising a hinged seat 104 having a rim surrounded by a recess and an aperture 500 under said hinged seat leading to two rollers 402, 404. The aperture 500 is adapted to receive a pan forming cartridge containing a commode liner comprising length of flexible tubular polymer material. The rollers 402,404 have a heat sealing element thereon arranged such that, in use, rotation of the rollers draws the tubular polymer material through the rollers and creates at least one seal therein so as to form a pouch for containing a user's excrement.

1 . A commode comprising:
 a hinged seat having a rim surrounded by a recess;   an aperture under said hinged seat leading to two rollers;   
       wherein said aperture receives therein a pan forming cartridge containing a commode liner comprising length of flexible tubular polymer material, and wherein said rollers have a heat sealing element thereon and rotation of said rollers draws the tubular polymer material through said rollers and creates at least one seal therein so as to form a pouch for containing a user's excrement. 
     
     
         2 . A commode according to  claim 1  wherein said heat sealing element comprises two heat sealers. 
     
     
         3 . A commode according to  claim 2  wherein one of said rollers has a cutter thereon and rotation of the rollers draws said tubular polymer material through the rollers and creates two seals and a cut therebetween so that said pouch is an individual pouch. 
     
     
         4 . A commode according to  claim 1  further comprising an extractor having an inlet adjacent the said aperture. 
     
     
         5 . A commode according to  claim 4  further comprising an extraction duct between said inlet and said extractor, said extraction duct having a Hepa filter therein. 
     
     
         6 . A commode according to  claim 5  further comprising a source of ultraviolet radiation located so as to irradiate said Hepa filter. 
     
     
         7 . A commode according to  claim 4  further comprising a seat cover movable between an open position and a closed position and wherein said inlet is located between said seat cover and said seat. 
     
     
         8 . A commode according to  claim 1  further comprising a cartridge for location under said seat within said aperture, said cartridge forming a pan and containing a commode liner comprising a length of flexible tubular polymer material. 
     
     
         9 . A commode according to  claim 6  wherein the diameter of said rollers is greater than the length of said commode liner between said rollers and said cartridge. 
     
     
         10 . A commode according to  claim 1  wherein the rollers have at least one radial recess therein to allow excrement within said commode liner to pass the rollers as they rotate. 
     
     
         11 . A commode according to  claim 1  wherein each roller has a pliable material thereon such that when said rollers are rotated the pliable material trap on opposing faces of the two rollers trap said commode liner therebetween. 
     
     
         12 . A commode according to  claim 7  further comprising an flush button thereon located in a position in which it is obscured by said seat cover when said seat cover is in its open position. 
     
     
         13 . A commode according  claim 1  further comprising a collection chamber beneath the rollers for collecting said pouches. 
     
     
         14 . A commode liner cartridge for use with the commode of  claim 1 , the cartridge comprising:
 a substantially hoop shaped container having a continuous opening around its upper edge, and a tubular sheet of flexible polymer film contained within the container and protruding through the continuous opening.   
     
     
         15 . A commode liner cartridge according to  claim 12  wherein said tubular sheet of flexible polymer film is sealed at its protruding end. 
     
     
         16 . A commode liner cartridge according to  claim 14  wherein said hoop shaped container comprises a plurality of ribs thereon on its inner and upper faces so as to encourage pleats to form in the film as it passes thereover. 
     
     
         17 . A commode liner cartridge according to  claim 14  wherein said cartridge contains a curved inner edge which, together with said liner sheet, forms a commode pan. 
     
     
         18 . A commode liner cartridge according to  claim 14  further comprising a feeder attached to the end of said commode liner and removably attached to the underside of said cartridge and by which said end of said commode liner can be fed into the rollers of a commode. 
     
     
         19 . A commode liner cartridge according to  claim 18  further comprising a piece of electrically conductive material attached to said feeder for completing a circuit when installed in a commode.
