The invention relates to a hospital bed with integrated toilet, consisting of a bed frame, a mattress topper and a mattress and a toilet placed in the middle of the hospital bed below the bed frame, wherein the bed frame has a two-part mattress topper, which is divided into four parts and the head-side mattress top consists of a headboard and a horizontally formed ramp, which are hinged together, and the foot-side mattress pad consists of a thigh part and a foot part, which are also hinged together.

In EP-05 38 077 A, such a hospital bed is described and illustrated. The hospital bed has a headboard and a footboard, which are separated from each other and has at the height of the joints of the head and footboard below the bed frame a fixed toilet bowl. In an embodiment of the hospital bed, the head part consists of a front and a rear head part, which are connected to one another in an articulated manner. The front head part is opposite the rear headboard upwards adjustable and the rear headboard is forward and backward movable together with the front headboard. The foot also consists of a front and rear foot, which are hinged together and up to this hinge against each other and are swung.

At rest, the headboard and footboard collided and together form a support for the patient. To use the toilet, the head part is moved in the direction of the head end and the front foot part is pivoted about the joint connecting the front and rear foot part upwards. When swinging the front foot part is made of a synthetic material, flexible cloth whose width corresponds to the bed width, the front end is attached to the front edge of the front foot part and un wound on a arranged under the bed frame roller, unwound from the roll and obliquely pulled from the bottom up over the resulting between the rear headboard and front foot opening. The cloth closes the opening and forms in the end position an obliquely staffed toilet seat with corresponding toilet opening for use of the fixed toilet bowl. After completion of the use of the toilet, the front footboard are lowered again, wherein the flexible cloth rolls up again on the roll, and then combined headboard and footboard to a support for the sick.

A disadvantage of this design of the hospital bed is that both the pivoting and lowering the front foot part of the leading edge and the toilet seat forming flexible cloth slide along the buttocks and bottom of the thighs of the patient and the prolonged lying already irritated or sore skin of the patient additionally attack and irritate.

Sick people who can not raise their lower body and legs with their own strength rely on outside help to avoid such friction movements on the critical parts of the body when using the toilet.
