The length of the first rack 323 is equal to the cross-sectional circumference of the first gear 313. When the first rack 323 is meshed with the first gear 313, the first gear 313 can rotate one circle, so that the bed board 2 can finish up-and-down fluctuation once. It should be noted that, the length of the first rack 323 may be greater than half the cross-sectional circumference of the first gear 313 and less than the cross-sectional circumference of the first gear 313, and the design may also enable the bed plate 2 to complete one up-and-down fluctuation.

The bed frame 1 is provided with a guide hole, two ends of the bed board 2 are provided with guide rods, and the guide rods are inserted into the guide hole and slide along the guide hole.

The number of the guide rod and the guide hole is two. By providing two plates, the bed board 2 can slide along the bed frame 1 more smoothly.

When the patient needs to massage, the controller controls the first motor to rotate so as to drive the first screw rod 321 to rotate, and the first adjusting block 322 continuously moves back and forth along the first screw rod 321. In this process, the first rack 323 on the first adjusting block 322 is sequentially engaged with each first gear 313, so as to sequentially drive each connecting rod 311 to rotate one turn, and the connecting rod 311 rotates one turn, that is, the eccentric 312 rotates one turn. When the eccentric wheel 312 rotates, the bed board 2 corresponding to the connecting rod 311 can slide up and down along the bed frame 1. When the bed board 2 moves upwards, the bed board 2 can lightly press the body of a patient, so that the patient can be helped to accelerate the blood circulation at the position, the muscle of the patient is prevented from atrophy, and the massage effect is achieved. Meanwhile, when the patient body is pressed, the body pressing part of the patient is lifted, a ventilation channel is formed, and the contact part of the patient and the bed board 2 is ventilated and cooled, so that the occurrence of bedsores can be reduced. Because the first adjusting block 322 moves back and forth, the bed board 2 moves up and down along with the movement of the first adjusting block 322, and the arrangement ensures that every part of the whole body of a patient can be fully massaged, and the rehabilitation effect is good.

This completes a drying cycle in which the skin of the patient in contact with the couch 2 is brought to a drying point and the couch 2 under the patient's body is dried, and if one cycle does not completely dry the patient's body and couch 2, the cycle is performed several times more.

After the patient body and the bed board 2 are completely dried, the controller controls the ninth motor to reversely rotate, the traction frame 74 reversely moves along the length direction of the bed frame 1, other door frames 721 also start to reversely move under the drive of the traction frame 74, and in the reverse movement process, the plurality of door frames 721 start to fold, so that the folding of the telescopic cover 72 is completed, and the telescopic cover 72 returns to the starting point. When the novel multifunctional sickbed is used, the sickbed cover 7 is automatically unfolded, and after the drying, the sickbed cover 7 is automatically folded, so that the sickbed space is not occupied. The invention can automatically blow-dry the body below the head of the patient, and simultaneously blow-dry the bed board 2, thereby having good integral drying effect. Avoiding illness or other discomfort of the patient in a moist environment, reducing nursing difficulty and nursing quantity and lowering nursing cost.

The sickbed cover 7 can also prevent the patient from suffering from cold, and can form a relatively closed environment when the sickbed cover 7 is unfolded in cold, and the air injection holes inject hot air, so that the closed environment can have a comfortable temperature, and the patient is prevented from suffering from cold.

The invention has simple integral structure, can automatically massage the whole body of a patient, prevent muscular atrophy, prevent bedsores and help the patient recover. Can automatically ventilate and dissipate heat to the skin of the patient at the contact position of the patient and the bed board 2, so that the body of the patient is relatively dry, and sores caused by heat and sweat are prevented. Can automatically replace the mattress and automatically bathe patients. The patient can conveniently relieve oneself in bed, can collect the stool and urine automatically, after excreting, can automatically wash clean patient's lower part of the body, can separate the collection to sewage and filth of washing the lower part of the body after bathing, prevent the polluted environment, improve resource utilization. The invention has high degree of automation, can realize multiple functions, can greatly reduce nursing workload and reduce nursing cost.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
