Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. A multifunctional medical bed, which is shown in figures 1 to 4 and comprises a bed frame 1, wherein a mattress is arranged on the bed frame 1; the mattress comprises a first mattress 4, a second mattress 5 and a third mattress 6, wherein one end of the second mattress 5 is hinged with the first mattress 4, and the other end of the second mattress 5 is hinged with the third mattress 6; a back lifting device is connected below the first mattress 4, and a translation device is connected below the second mattress 5; a circular groove is formed in the middle of the second mattress 5, a rotary mattress 7 is arranged in the groove, and a rotary motor 9 is connected below the rotary mattress 7 through a rotating shaft 8; the lower part of the bedstead 1 is connected with a mounting platform 10, and the back lifting device and the translation device are both positioned on the mounting platform 10.

The back lifting device comprises a servo motor 11, a sliding plate 12 is connected below the servo motor 11, and the sliding plate 12 is connected to the mounting platform 10 in a sliding manner; a horizontally arranged screw rod 13 is connected to the servo motor 11, and a sliding block 14 is connected to the screw rod 13 in a threaded manner; a back lifting push rod 15 is rotatably connected to the sliding block 14, the top end of the back lifting push rod 15 is hinged to the first mattress 4, and a connecting rod 21 is connected between the top of the servo motor 11 and the second mattress 5; the translation device comprises a driving motor 16, a transmission gear 17 and a rack 18, the transmission gear 17 is connected with the driving motor 16, the transmission gear 17 is meshed with the rack 18, and the rack 18 is positioned on the bottom surfaces of two side edges of the second mattress 5; the side edge of the bedstead 1 is provided with a guide groove 19 at the position corresponding to the rack 18, and the driving motor 16 is arranged on the mounting platform 10; the middle part of the mounting platform 10 is provided with a slot 2, and the position of the slot 2 corresponds to the translation path of the rotating shaft 8; the bottom of the rotating motor 9 is provided with a supporting platform 3 connected on the bedstead 1, and the bottom of the bedstead 1 is connected with universal wheels 20.

The working principle is as follows: when the mattress is used, the servo motor 11 is started, the servo motor 11 drives the screw rod 13 to rotate, the slide block 14 on the screw rod 13 moves towards the third mattress 6 along the screw rod 13 horizontally, and therefore the back lifting push rod 15 pushes the first mattress 4 to turn obliquely (as shown in fig. 4); then the driving motor 16 is started to drive the transmission gear 17 to rotate, the transmission gear 17 drives the rack 18 to move horizontally, so that the second mattress 5 moves towards the third mattress 6 along the bedstead 1, and the third mattress 6 is pushed to move out of the bedstead 1; after the third mattress 6 is moved out of the bedstead 1, the third mattress is turned downwards by 90 degrees under the action of self gravity, and at the moment, the leg of the patient turns downwards along with the third mattress 6 to be bent (sitting posture); when second mattress 5 moves, first mattress 4 moves along with second mattress 5, and second mattress 5 passes through connecting rod 21 and drives servo motor 11, lead screw 13 and slider 14 and move along slide 12 together to when making the patient along with second mattress 5 horizontal migration, first mattress 4 remains the state of getting up the back all the time, maintains that patient's back is in the position of sitting state.
