Abstract
Abstract A vacuum commode is provided in which a bed pan has a sponge rubber seat cushion arranged between the bed pan and the user of the assembly. Inserted between the user and the seat cushion is a hand bulb air pump which is used to create a partial vacuum within the interior of the bed pan. The partial vacuum may be created because the rubber seat and a flexible plastic sheet spread over the patient's lap area provide an air-tight seal between the user and the interior air space of the bed pan. The air pump is used to create a partial vacuum within the interior of the bed pan which causes a suction-like effect therein, thus aiding in the excretion of waste matter from the bowels of the user.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
224 words
A commode comprising: (a) a waste receptacle having an upper aperture to serve as a seat for a user, and an interior portion; (b) means for providing an air-tight seal between a commode user seated on the aperture and said receptacle; and (c) means for creating a partial vacuum by reducing the air pressure within the receptacle as closed off by the user and said sealing means relative to the air pressure acting upon the body of the user for the purpose of aiding in defecation by the user into the receptacle, wherein said sealing means comprises a cushion formed of soft sponge rubber adapted to encircle said aperture of said receptacle, said cushion having an underside portion thereof provided with suction cups to secure and seal said seat to said receptacle, wherein said sealing means further comprises a sheet of flexible plastic material which is spread over a commode user's lap and inner leg area, said seat providing an air-tight seal between said commode user and said receptacle and said sheet means further preventing air leakage from the atmosphere to the receptacle inwardly through a space existing between said user's legs; and wherein said commode user by seating and adjusting himself upon said cushion causes a partial expelling of air from within the interior of the receptacle through the partial vacuum creating means.
Claim 2
Dependent Claim

A commode comprising: (a) a waste receptacle having an upper aperture to serve as a seat for a user, and an interior portion; (b) means for providing an air-tight seal between a commode user seated on the aperture and said receptacle; and (c) means for creating a partial vacuum by reducing the air pressure within the receptacle as closed off by the user and said sealing means relative to the air pressure acting upon the body of the user for the purpose of aiding in defecation by the user into the receptacle, wherein said sealing means comprises a cushion formed of soft sponge rubber adapted to encircle said aperture of said receptacle, said cushion having an underside portion thereof provided with suction cups to secure and seal said seat to said receptacle, wherein said sealing means further comprises a sheet of flexible plastic material which is spread over a commode user's lap and inner leg area, said seat providing an air-tight seal between said commode user and said receptacle and said sheet means further preventing air leakage from the atmosphere to the receptacle inwardly through a space existing between said user's legs; and wherein said commode user by seating and adjusting himself upon said cushion causes a partial expelling of air from within the interior of the receptacle through the partial vacuum creating means.
Claim 3
Dependent Claim
81 words
The commode of claim 1 wherein said partial vacuum creating means comprises a hand bulb air pump with an exhaust valve, said pump being operatively connected to a hose which is placed between the commode user and said cushion and is disposed within the interior of said receptacle so that when said bulb is compressed and released a predetermined number of times by said commode user, a partial vacuum results in said receptacle which thereby aids said commode user in defecation.
Claim 4
Dependent Claim
35 words
The commode of claim 2 wherein said hose is adapted to be operatively connected with a stopper to a vacuum cleaner intake hose so that a larger partial vacuum may be created within said receptacle.
Claim 5
Dependent Claim
12 words
The commode of claim 3 wherein said receptacle is a bed pan.
Claim 6
Dependent Claim
82 words
The commode of claim 2 wherein said receptacle is a slop jar and a substantially longitudinal upper board having an aperture is disposed between said slop jar and said cushion seat, and a lower board provided with cross ribs is disposed beneath said slop jar so that a commode user may rock himself back and forth by grasping the outer ends of said upper board, whereby a jolting and joggling effect is imparted to the lower back area of said commode user.
Claim 7
Dependent Claim
37 words
The commode of claim 5 wherein said hose is adapted to be operatively connected with a stopper to a vacuum cleaner intake hose so that a larger partial vacuum may be created within said slop jar. pg,14
Claim 8
Dependent Claim
57 words
The commode of claim 2 wherein said receptacle is a ceramic toilet bowl having a water trap and a removable plug, wherein a substantially longitudinal board having an aperture is disposed between said cushion and said toilet bowl, said plug having a tug line secured thereto and extending underneath said board and depending outside of said bowl.
Claim 9
Dependent Claim
35 words
The commode of claim 7 wherein said hose is adapted to be operatively connected with a stopper to a vacuum cleaner intake hose so that a larger partial vacuum may be created within said bowl.
