The invention relates to a method for removing a chemical substance from human excreta, such as faeces and urine, comprising the following steps of: providing a toilet for a person from whose excreta the chemical substance must be removed; releasably connecting a filtering device to the toilet, wherein the filtering device comprises at least one removable cartridge with a filter; transporting the excreta by means of a transport screw from the toilet toward the filter in the cartridge, wherein pressure is exerted on the excreta by means of a plunger; filtering the chemical substance out of the excreta in situ using the filtering device; periodically replacing the at least one cartridge; and processing the replaced cartridge. The invention also relates to a filtering device for application in this method, and a cartridge for use in such a filtering device.

The present invention relates generally to the field of toilets. More specifically, the present invention relates to a portable toilet system primarily comprised of at least one inflatable toilet, at least one privacy screen, and at least one pump. The inflatable toilet can further be inflated, manually or using the pump, wherein the privacy screen can then be erected around the toilet such that a user can defecate or urinate in a bowl member within the toilet that has a waste bag liner. The system may also be comprised of wet wipes and a water bottle to allow a user to clean themselves. All components of the system may further be stored within a carrying case.

A toilet is disclosed. The toilet has a bowl adapted to receive feces, a shelf for receiving feces in the bowl, a mechanism that places a consumable material on the shelf between uses of the toilet, and a removal mechanism for removing the feces and the consumable material from the bowl. The consumable material on the shelf is to separate feces from the shelf.

A nursing bed for defecation and self-cleaning comprises a bed frame, a bed board device, a moveable cushion, a support frame, a bedpan, an excreta container; The bedpan is hung under the movable cushion through a support frame. When the patient wants to defecate, the patient only needs to remove a cushion and make the bedpan mouth of the bedpan facing the defecation hole of the moveable cushion, then the patient can defecate on the nursing bed; and further having a cleaning device a warm water supply device, using an electric heater to heat the cleaning water to an appropriate temperature to clean the patient's buttocks, thereby reducing the infection of germs, and also cleaning the excrement that attached to the bedpan to keeps the bedpan clean.

A portable toilet is mounted on a skid. The skid has a pair of horizontal members with a terminal end with a vertically oriented hole. A leveler affixed to the horizontal member at the terminal end via a connector with a first vertical hole laterally spaced away from a second vertical hole. An anchor bolt is associated with the first vertical hole and engageable with the vertically oriented hole in the skid's horizontal member, thereby fastening the leveler to the toilet. A leveler bolt is threadingly engaging the second vertical hole for movement in a vertical direction in relationship to the toilet; and a foot associated with a lower terminal end of the leveler bolt. Whereby when the leveler is anchored to the skid and the leveler bolt is engaged with the foot, the portable toilet may be leveled by movement of the leveler bolt.
