In the invention, when a patient needs to be massaged, the controller controls the first motor to rotate to drive the first screw rod 41 to rotate, and the first adjusting block 42 moves from one end of the bed frame 1 to the other end and returns to the original position, so that the bed board 2 on the bed frame 1 sequentially rises and falls from the tailstock to the head of the bed or from the head of the bed to the tailstock. When bed board 2 upwards slided, patient's health can be pressed gently to bed board 2, can play the massage effect, can help the patient to accelerate this blood circulation, prevents that patient's muscle from appearing atrophiing. Meanwhile, when the body of the patient is pressed, the pressed part of the body of the patient is lifted, a ventilation channel is formed, and the structure can reduce the occurrence of bedsore. Because the first adjusting block 42 does reciprocating motion, every part of the whole body of the patient can be pressed by the bed plate 2, and the arrangement can fully massage the patient and further prevent the muscle of the patient from shrinking.

When the part of the patient contacting with the bed plate 2 is wet, the controller controls the second motor to rotate to drive the second screw 51 to rotate, the second rack 53 on the second adjusting block 52 is meshed with the group of fourth gears 36, the group of bed plates 2 are lifted upwards, a group of gaps are formed at the contacting part of the group of bed plates 2 and the patient, and the second motor stops working. At this time, the ventilation holes 54 corresponding to the set of bed plates 2 begin to blow hot air to the gaps, and take away moisture and heat on the skin of the patient. The ventilation holes 54 stop blowing air for a period of time, the controller controls the second motor to rotate in the opposite direction, the second rack 53 on the second adjusting block 52 is meshed with the other group of fourth gears 36, the other group of bed plates 2 is lifted upwards, a group of gaps are formed at the contact positions of the group of bed plates 2 and the patient, and the second motor stops working. At this time, the ventilation holes 54 corresponding to the set of bed plates 2 begin to blow hot air to the gaps, and take away moisture and heat on the skin of the patient. The above steps complete a heat dissipation and drying cycle in which the skin of the patient in contact with the bed plate 2 can be dissipated and dried, and if one cycle cannot completely dry the skin of the patient, the cycle is repeated for a plurality of times. This heat dissipation drying mechanism 5 simple structure can make the skin drying on one's body of patient fast, avoids decubital emergence, and degree of automation is high, can reduce the nursing degree of difficulty and cost.

When the mattress needs to be changed, a clean mattress and a dirty mattress are connected at the tailstock, the controller controls the third motor to rotate and the fifth motor to rotate, the second group of bed boards 2 and the transmission structure 621 rise simultaneously, the first group of first transmission wheels 6211 rotates to transmit one section of mattress at the tailstock to the first group of bed boards 2, the second group of bed boards 2 and the transmission structure 621 fall down, and in the step, one section of mattress at the tailstock is sent to the first group of bed boards 2. The controller controls the rotation of the fourth motor and the rotation of the fifth motor, the third set of bed slats 2 and the transfer structure 621 being raised simultaneously, the second set of first transfer wheels 6211 being rotated to transfer the mattress from the position of the first set of bed slats 2 to the position of the second set of bed slats 2, the third set of bed slats 2 and the transfer structure 621 being lowered, in which step the mattress at the first set of bed slats 2 is sent to the second set of bed slats 2. The controller controls the fourth motor to rotate in the reverse direction and the fifth motor to rotate, the first group of bed boards 2 and the transfer structure 621 are lifted at the same time, the third group of first transfer wheels 6211 transfer the mattress from the position of the second group of bed boards 2 to the position of the third group of bed boards 2 forward, the first group of bed boards 2 and the transfer structure 621 fall down, and in this step, the mattress at the second group of bed boards 2 is sent to the third group of bed boards 2. The above steps complete a cycle, in which a section of mattress at the end of the bed is transferred to the position of the third group of bed boards 2, that is, the mattress completes the transfer of 3 bed boards 2 in the cycle, the above cycle continues once, the section of mattress at the end of the bed completes the transfer of 6 bed boards 2, and the other section of mattress at the end of the bed is transferred to the position of the third group of bed boards 2. The cycle is repeated so that the mattress is transferred from the foot to the head of the bed, and when the dirty mattress is completely transferred, a clean mattress is also laid on the bed plate 2. The invention has simple structure, and can transfer the mattress from one end of the bedstead 1 to the other end section by controlling the fluctuation of the bed board 2 and the rotation of the first transfer wheel 6211, and when the dirty mattress is taken down, a clean mattress is laid. The change is efficient, and whole process is whole by multi-functional medical sick bed automatic control, and degree of automation is high, has reduced artifical nursing work load, has reduced the nursing expense. In the whole process of replacing the mattress, the patient does not need to be moved and turned, and the injury to the patient is avoided.

According to the invention, the massage mechanism 4 is arranged, so that the whole body of a patient can be automatically pressed, the blood circulation of the patient can be accelerated, the muscle atrophy of the patient can be prevented, the recovery of the patient is facilitated, the heat dissipation drying mechanism 5 is arranged, the patient can be in a dry and comfortable environment, the bedsore of the patient can be prevented, and the recovery of the patient is facilitated. Through setting up automatic mattress changing mechanism 6, the new mattress has already been laid when making dirty mattress change, and is efficient, need not remove simultaneously and turn the patient, further does benefit to the patient and recovers. When massaging, radiating, drying and changing the mattress for the patient, the multifunctional medical sickbed is basically automatically used, the degree of automation is high, the manual nursing amount and the nursing difficulty are reduced, and the nursing cost is reduced.

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.
