Description

Technical Field

[0001] The invention relates to the technical field of hospital beds, and in particular to a hospital bed which is convenient for bedridden patients to go to the toilet. Background Art

[0002] At present, many bedridden patients who are hospitalized are not suitable for or cannot get out of bed to urinate or defecate. They can only use urinals and bedpans on the hospital bed. This will cause an uncomfortable and embarrassing toilet experience for bedridden patients. At the same time, it is easy to contaminate the bed, causing great trouble to caregivers and medical staff. They may even be unable to complete toileting in a lying position because the (semi-) lying toilet posture is different from the conventional sitting toilet posture, and have to use a wheelchair, or be supported or carried on the back to the toilet.

[0003] At present, most ordinary beds are not equipped with toilets, making it inconvenient for bedridden patients to go to the toilet. Even if some beds are equipped with toilets, due to the small capacity of the toilets, the number of times bedridden patients can go to the toilet is limited, and the excrement needs to be cleaned frequently, which is inconvenient, increasing the difficulty of care and work intensity for caregivers. In addition, if the excrement is not cleaned in time, it will also reduce the user's comfort level, increase the mental burden of bedridden patients, and slow down their own recovery.

[0004] Application No. 201320787011.X discloses a bed that is convenient for paralyzed patients to use the toilet. Although the bed can enable paralyzed patients to sit up and use the toilet, after using the toilet, the caregiver needs to personally clean the paralyzed patient's buttocks, remove the bedpan from the through hole for using the toilet, and then fill the through hole with a cushion of similar size or other fillings, and then clean the bedpan filled with feces and urine, which brings great service pressure to the caregiver.

[0005] Application No. 202110609794.1 discloses a multifunctional electric hospital bed. Although it solves the user's toilet problem and realizes the sewage discharge, storage and cleaning functions of the smart toilet, nursing staff are still required to clean the sewage tank regularly, and the labor intensity of nursing staff is still very high.

[0053] How this bed, which makes it easier for bedridden patients to use the toilet, works:

[0054] (1) When the bedridden patient wants to sit down to rest, eat or go to the toilet, the motor 207 drives the screw 202 to rotate forward and drives the sliding seat 203 to move backward. The sliding seat 203 that moves backward will drive the hinge 204 and the bed backboard 107 to flip forward to a vertical position. At the same time, the sliding seat 203 that moves backward will push the bed leg board 109 to flip backward to a vertical position, and the flipped bed leg board 109 will drive the bed foot board 110 to descend. When the bedridden patient wants to lie down to rest, the motor 207 drives the screw 202 to rotate backward and drives the sliding seat 203 to move forward. The sliding seat 203 that moves forward will drive the hinge 204 and the bed backboard 107 to flip backward to a horizontal position. At the same time, the sliding seat 203 that moves forward will push the bed leg board 109 to flip forward to a horizontal position, and the flipped bed leg board 109 will drive the bed foot board 110 to be flush with the bed hip board 108.

[0055] (2) When the bedridden patient wants to sit down to use the toilet, the motor 2 307 drives the screw 2 312 to rotate forward and drives the pair of sliders 1 310 on the guide rail 1 309 to move closer to each other, thereby driving the hinge frame 317 to expand upward and abut the smart toilet 303 on the lifting plate 302 against the edge of the toilet opening 1082a. When the bedridden patient finishes using the toilet, the patient's buttocks are cleaned and dried by the two functions of warm water washing and warm air drying of the smart toilet 303, and then the motor 2 307 drives the screw 2 312 to rotate reversely and drives the pair of sliders 1 310 on the guide rail 1 309 to move away from each other, thereby driving the hinge frame 317 to retract downward and lower the smart toilet 303 on the lifting plate 302 to the right below the toilet opening 1082a. Finally, the smart toilet 303 is self-cleaned after use by the automatic water supply and discharge, automatic sterilization and deodorization functions of the smart toilet 303.

[0056] (3) When the bedridden patient wants to sit on the smart toilet 303 to use the toilet, the upward-moving lifting plate 302 drives a pair of inverted "eight"-shaped linkage bars 407 to expand horizontally, thereby driving the opening and closing cover 406 to move downward along the guide groove 409a first and then move horizontally outward, thereby allowing the opening and closing cover 406 to automatically move away from the toilet opening 1082a, so that the smart toilet 303 can abut against the toilet opening 1082a. When the bedridden patient finishes using the toilet, the downward-moving lifting plate 302 drives a pair of inverted "eight"-shaped linkage bars 407 to retract horizontally, thereby driving the opening and closing cover 406 to move horizontally inward along the guide groove 409a first and then move upward, thereby allowing the opening and closing cover 406 to close again at the toilet opening 1082a, thereby preventing people from manually opening or closing the opening and closing cover 406.

[0057] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
