The controller controls the spray head 42 to start spraying water. The water sprayed from the water spray holes washes the front, side and back of the patient and also washes the bed plate 2. The controller controls the third motor to rotate, and the bed plate 2 which slides downwards slides upwards. The second motor and the fourth motor continue to work, the spray head 42 moves to another bed plate 2, the bed plate 2 slides downwards, and the controller controls the spray head 42 to wash the front, the side and the back of the patient and the bed plate 2. Repeating the above steps, the spray head 42 is continuously moved to wash the area around the lower body of the patient.

(4) The controller controls the second motor to rotate and the third motor to rotate, so as to ensure that at least one bed board 2 on the bed frame 1 is descended, and a gap is formed between the bed board 2 and the patient. The controller controls the gas spraying head to start gas spraying. The air ejected from the air ejection holes blows the front, the side and the back of the patient and also blows the bed board 2. Repeating the steps, and blowing the whole body of the patient and the bed board 2 by the air injection holes.

(5) The nursing staff presss from both sides the one end of the quilt in storing storehouse on the holder outside bedspread 5, and controller control sixth motor is rotatory, and the holder pulls the quilt and removes to the head of a bed from the tailstock, and when removing patient shoulder position, the gyro wheel rolls along the inclined plane, and the clip is loosened, and the quilt falls on one's body on the patient. This arrangement prevents the quilt from covering the head of the patient and causing discomfort to the patient. The controller controls the sixth motor to rotate reversely, and the clamping piece moves to the bed tail. The quilt cover can automatically cover the quilt for the patient, the individual privacy of the patient is protected, the embarrassment of nursing staff is avoided, and meanwhile the workload of the nursing staff is reduced.

(6) The controller controls the spray head 42 to return to the home position, and the controller controls the bed cover 5 to fold and return to the home position.

(7) The first motor of controller control is rotatory, collects funnel 61 from the bed automatic sliding to the bed outside, and the nursing staff is packed the bag of accomodating on with collecting funnel 61 and is lost the garbage bin, has the bag of accomodating on the collecting funnel 61, and the first motor counter-rotation of controller control is collected funnel 61 from the bed automatic sliding to the bed below. The collection funnel 61 has no storage bag, and the nursing staff lays a plurality of storage bags on the storage bag and fixes the storage bags, and then the collection funnel 61 is controlled by the controller to return to the position under the bed.

The invention has simple structure, can monitor the excretion of the patient in time after the patient excretes, automatically unfold and use the bedspread 5, automatically clean the lower body and the bed board 2 of the patient, automatically dry the body and the bed board 2 of the patient, automatically cover the quilt on the patient, uniformly collect dirty water and dirt, and does not pollute the environment. Whole flow automation degree is high, and the patient can in time be washd and settle, has improved nursing effect, has protected patient's individual privacy simultaneously, and secondly, the disposable use of accomodating the bag has saved the nursing time. The invention reduces the workload of nursing staff and the nursing cost on the whole.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
