The ventilation holes 11 stop blowing air for a period of time, the controller controls the second motor to rotate in the opposite direction, the second racks 43 on the second adjusting block 42 are meshed with the second gear 314 of the group B, the bed plate 2 of the group B is lifted upwards, a gap is formed at the contact position of the bed plate 2 of the group A and a patient, and the second motor stops working. At this time, the vent holes 11 corresponding to the bed plate 2 of the group A blow hot air to the gap, so as to dry the moisture on the surface of the patient body and the bed plate 2 below the patient body. To this end, a drying cycle is completed in which the skin of the patient in contact with the bed plate 2 is dried to a dry spot and the bed plate 2 under the patient's body is dried to a dry spot, and if one cycle cannot completely dry the patient's body and the bed plate 2, a cycle is performed several times more.

After the body of the patient and the bed board 2 are completely dried, the controller controls the ninth motor to rotate reversely, the traction frame 74 moves reversely along the length direction of the bed frame 1, other door frames 721 also start to move reversely under the driving of the traction frame 74, during the reverse movement, the door frames 721 start to be folded, so that the folding of the telescopic cover body 72 is completed, and the telescopic cover body 72 returns to the starting point. When the sickbed cover is used, the sickbed cover 7 is automatically unfolded, and after the sickbed cover is dried, the sickbed cover 7 is automatically folded, so that the sickbed space is not occupied. The invention can automatically blow the body below the head of the patient, and also blow the bed board 2, and has good overall drying effect. Avoids the illness or other discomfort of the patient in a humid environment, reduces the nursing difficulty and the nursing amount, and reduces the nursing cost.

The sickbed cover 7 can also prevent a patient from getting cold and getting sick, when the sickbed cover 7 is cold, a relatively closed environment can be formed when the sickbed cover is unfolded, and the air injection holes spray hot air, so that the closed environment can have a comfortable temperature, and the patient is prevented from getting sick due to cold.

The invention has simple integral structure, can automatically massage the whole body of a patient, prevent muscular atrophy and bedsore generation and help the patient to recover. Can automatically ventilate and radiate the skin of the contact position of the patient and the bed plate 2, so that the body of the patient is relatively dry, and the sore caused by heating and sweating is prevented. The mattress can be automatically replaced, and the patient can be bathed automatically. The patient can conveniently be in bed stool and urine, can collect stool and urine automatically, excrete the back, can wash clean patient's the lower part of the body automatically, can separate the collection with sewage and the filth that washes the lower part of the body after bathing, prevent polluted environment, improve resource utilization. The invention has high automation degree, can realize multiple functions, and can greatly reduce the nursing workload and the nursing cost.

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.
