Abstract
Abstract A bed for a patient comprising a cover plate and a flush pot for patient''s excretion arranged below the bed and adapted to move vertically and horizontally. The cover plate normally closes a hole formed in the bed for a normal use as a bed and when desired the cover plate automatically lowers and horizontally moves away from the position and simultaneously the flush pot moves to the position immediately below the hole of the bed and raise to a position that the upper periphery of the pot is in flush with the upper surface of the bed, so that patient''s buttocks comes into closely contact with the pot and are supported thereon to reduce a chamber of stain of the bed. The bed is provided with a pump motor for flushing and injection of cleaning water against the patient''s excretory organ after excretion, and a fan motor for ventilation and warm wind injection for drying the organ after cleaned.

Total Claims: 6
Claim 1
Independent Claim
305 words
A bed for a patient, comprising a base frame, and a thick first mat on the base frame, the first mat and The base frame being formed with a hole, and the bed further comprising: a cover plate with a second mat arranged below said first mat and vertically movable upwardly into said hole formed in said first mat and said base frame to snugly close said hole and downwardly away from said hole to open the same, the upper surfaces of said two mats being substantially flush with each other to provide a comfortable support for the patient when said second mat is in said hole of said first mat; a flush pot for the patient''s excretion arranged below said first mat and vertically movable upwardly into said hole of said mat and said base frame in place of said second mat to such a level that the rim of said pot is flush with the upper surface of the first mat and downwardly away from said hole; a support frame for supporting said cover plate with said second mat and said flush pot side by side; lifting guides arranged in said support frame for vertically guiding said cover plate with said second mat and said flush pot, respectively; lifting mechanisms for separately lifting said cover plate and said pot along said guides, respectively; rails fixed with respect to said base frame and on which said support frame is movably mounted; and a driving mechanism for horizontally reciprocatingly moving said support frame along said rails to move said cover plate from a first position corresponding to the center of said hole to a second position spaced from said first position and simultaneously to move said pot from a first position to a second position corresponding to the center of said hole and vice versa.
Claim 2
Dependent Claim
305 words
A bed for a patient, comprising a base frame, and a thick first mat on the base frame, the first mat and The base frame being formed with a hole, and the bed further comprising: a cover plate with a second mat arranged below said first mat and vertically movable upwardly into said hole formed in said first mat and said base frame to snugly close said hole and downwardly away from said hole to open the same, the upper surfaces of said two mats being substantially flush with each other to provide a comfortable support for the patient when said second mat is in said hole of said first mat; a flush pot for the patient''s excretion arranged below said first mat and vertically movable upwardly into said hole of said mat and said base frame in place of said second mat to such a level that the rim of said pot is flush with the upper surface of the first mat and downwardly away from said hole; a support frame for supporting said cover plate with said second mat and said flush pot side by side; lifting guides arranged in said support frame for vertically guiding said cover plate with said second mat and said flush pot, respectively; lifting mechanisms for separately lifting said cover plate and said pot along said guides, respectively; rails fixed with respect to said base frame and on which said support frame is movably mounted; and a driving mechanism for horizontally reciprocatingly moving said support frame along said rails to move said cover plate from a first position corresponding to the center of said hole to a second position spaced from said first position and simultaneously to move said pot from a first position to a second position corresponding to the center of said hole and vice versa.
