Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
104 words
A device for covering an opening for the discharge of metabolic products from the human body and which includes means for venting the opening, the device comprising a disc of an odor removing filter material and gas tight cover material in gas tight contact with the filter material, the cover material being provided with inlet and outlet openings, at least one of the openings being located at the edge of the disc and the other being located such that gas being vented has to pass through the filter material a distance of at least 5 times the thickness of the disc of filter material.
Claim 2
Independent Claim
104 words
A device for covering an opening for the discharge of metabolic products from the human body and which includes means for venting the opening, the device comprising a disc of an odor removing filter material and gas tight cover material in gas tight contact with the filter material, the cover material being provided with inlet and outlet openings, at least one of the openings being located at the edge of the disc and the other being located such that gas being vented has to pass through the filter material a distance of at least 5 times the thickness of the disc of filter material.
Claim 3
Dependent Claim
56 words
A device according to claim 1 in which there is an opening through the disc, the inlet for gases to be vented is around the edge of the opening, the outlet is around the outer edge of the disc, and there are means to prevent the direct escape of gases from the device across the opening.
Claim 4
Dependent Claim
17 words
A device according to claim 2 in which the disc is circular and the opening is central.
Claim 5
Dependent Claim
37 words
A device according to claim 2 or claim 3 in which the means to prevent the direct escape of gases comprises the gas tight cover material extending across and hermetically sealing the central opening of the disc.
Claim 6
Dependent Claim
31 words
A device according to claim 2 or claim 3 in which the means to prevent the direct escape of gases comprises a pouch for collecting fecal matter from the body opening.
Claim 7
Dependent Claim
49 words
A device according to claim 5 in which the cover material on one side of the disc distant from the pouch does not extend across the opening in the disc and there are means for holding the device in position with that side of the disc adjacent the skin.
Claim 8
Dependent Claim
64 words
A device according to claim 5 in which cover material on the side of the disc distant from the pouch extends across and seals the opening and the pouch includes an inlet opening, distant from the disc, for receiving fecal matter from the body opening, and means for holding the device in position with the inlet opening of the pouch against the body opening.
Claim 9
Dependent Claim
22 words
A device according to claim 6 or claim 7 in which the means for holding the device in position comprise adhesive material.
Claim 10
Independent Claim
31 words
A device according to any of claims 5 to 7 in which the pouch is adhesive bonded to the cover material covering the disc on the pouch side of the disc.
Claim 11
Independent Claim
32 words
A device according to any of claims 2 to 9 in which the cover material on each side of the disc carries, on its surface distant from the disc, an adhesive material.
Claim 12
Independent Claim
