Description
Technical Field
The invention belongs to the technical field of nursing apparatuses, and particularly relates to an auxiliary defecation nursing bed and an auxiliary defecation method thereof.
Background
With the acceleration of the life pace of the modern society, many children are busy with working and do not care for their parents, and the children should be the daily main caretaker of the old, but the current '4-2-1 family structure' causes more and more old people to 'care for the absence'. At present, the old in a large number of years is generally given to a nurse or a nursing home for nursing, but the old is often not well cared for due to some reasons, and even events of the nurse for treating the old are reported.
For the elderly who cannot self-care in life, defecation is very difficult without assistance. This results in the elderly often having a direct bowel movement in the bed when the caregivers are not present. The contradiction between the old and the cared person caused by the method is not enumerated. Therefore, it is important to design a nursing bed which can assist the old to directly relieve the bowels on the bed without polluting the bed body.

The output shaft of the sliding motor is fixed with the sliding gear. The sliding rack and the sliding cover plate 6-2 are fixed. The sliding gear is meshed with the sliding rack. The drying fan 6-3 and the cleaning spray pipe 6-4 are both fixed with the bed frame 1 and positioned below the backboard 2. The air outlet of the drying fan 6-3 and the water outlet of the cleaning spray pipe 6-4 are inclined towards the defecation through groove on the hip plate 3.
The sheet replacing mechanism located right below the backboard 2 includes an elongated sheet, an output roller 7, an output motor 15, a recovery roller 14, and a recovery motor 16. The output roller 7 and the recovery roller 14 are supported on both sides of the bed frame 1. The length of the take-off drum 7 and the recovery drum 14 is equal to the width of the hip plate 3. The output motor 15 and the recovery motor 16 are both fixed on the bed frame 1. The output shafts of the output motor 15 and the recovery motor 16 are fixed to the output roller 7 and the recovery roller 14, respectively. The output roller 7, the recovery roller 14 and the bed frame 1 are all detachably connected.
The strip-shaped bed sheet bypasses the top surface of the backboard 2, and the two ends are respectively rolled on the back output roller 7 and the recovery roller 14. The edge of the strip-shaped bed sheet, which is close to the back plate 2, is provided with a plurality of defecation notches. The shape of the defecation notch is the same as the cross section shape of the defecation through groove on the hip plate 3. The plurality of defecation notches are uniformly distributed along the length direction of the strip-shaped bed sheet. The distance between two adjacent defecation notches is equal to g. g is the length of the back plate 2.
In the initial state, the top surfaces of the backboard 2, the hip board 3, the thigh board 4 and the shank board 5 are all horizontally arranged. The lifting plate 6-1 is positioned in the defecation through groove. The slip cover plate 6-2 is located inside the lift plate 6-1. Two adjacent defecation notches on the strip-shaped bed sheet are respectively positioned at two ends of the backboard 2. The part of the strip-shaped bed sheet above the backboard 2 is pressed by the lifting plate 6-1. Since the lifting plate 6-1 presses the long sheet, the long sheet is not supported when the lifting plate is turned up. In the state that the backboard 2 is turned up, the sliding cover board 6-2 can slide out of the range of the lifting board 6-1 through the yielding gap on the backboard 2.
The auxiliary defecation nursing bed comprises the following specific steps:
when the cared person needs to relieve the bowels or the humidity sensor detects that the long-strip-shaped bed sheet is soaked, the first overturning motor 12 and the second overturning motor 9 rotate positively, so that the backboard 2 and the thigh board 4 are overturned upwards. The lower leg plate 5 slides and turns over under the drive of the thigh plate 4. So that the caregivers sit up and the joints of the lower leg plates 5 and the thigh plates 4 can support the knee joints of the caregivers.
Step two, the lifting motor rotates positively, and the lifting plate 6-1 turns upwards, so that the buttocks of the cared person are lifted, and the cared person does not squeeze the long-strip-shaped bed sheet any more.
And thirdly, synchronously rotating the output motor 15 and the recovery motor 16 forward to enable the strip-shaped bed sheet on the output roller 7 to be rolled out until a defecation notch on the strip-shaped bed sheet is aligned with a defecation through groove on the hip plate 3.
Meanwhile, the sliding motor rotates positively, so that the sliding cover plate 6-2 slides to the lower part of the back plate 2, and is not blocked by objects between the buttocks of a nursing person and the excrement collecting barrel.
And fourthly, reversing the lifting motor, and overturning the lifting plate 6-1 downwards to a horizontal state. The cared person starts defecation.
And fifthly, after the defecation of the nursed person is finished, the cleaning water spray pipe 6-4 sprays cleaning water flow to clean the buttocks of the nursed person.
And step six, after the buttocks of the cared person are cleaned, the cleaning water spraying pipe 6-4 stops spraying water. The drying fan 6-3 is started to dry the buttocks of the cared person.
And step seven, the lifting motor rotates positively, and the lifting plate 6-1 turns upwards, so that the buttocks of the cared person are lifted, and the cared person does not squeeze the long-strip-shaped bed sheet any more.
And step eight, reversing the sliding motor to reset the sliding cover plate 6-2. Simultaneously, the output motor 15 and the recovery motor 16 synchronously rotate forward, so that the strip-shaped bed sheet on the output roller 7 is rolled out until the top surface of the hip plate 3, which is separated from the defecation notch aligned with the defecation through groove on the hip plate 3, is reached.
Step nine, the lifting motor is reversed, and the lifting plate 6-1 is turned down to be in a horizontal state.
Step ten, the first turnover motor 12 and the second turnover motor 9 are all reversed, so that the backboard 2, the thigh board 4 and the shank board 5 are all restored to the horizontal state.
