Principle of operation

Firstly, turning down the bed side baffle 20 at one side to enable a patient to lie on the bed body 11, then turning up the bed side baffle 20 to fix the patient to prevent the patient from falling, and clamping the sheet by using the fixing plates 42 and the clamping plates 38 arranged at two sides;

when a patient wants to actively perform the turnover rehabilitation training, the hand at the healthy side is lifted to hold the handle 14 at the healthy side, the holding plate 17 is pressed into the handle fixing column 16, and the ratchet arc plates 33 arranged at the two sides of the force-assisted half ring 27 along with the pressing of the holding plate 17 are pushed out under the action of the ratchet arc plate columns 34;

the patient then pushes the handle 14 up to the desired height, where the patient is provided with a supporting force because the ratchets arranged between the power-assisted slider 29 and the ratchet arc 33 are respectively oriented in different directions and thus cannot slide;

when the patient pushes the handle 14, the sliding rail 28 is arranged in the power-assisted sliding member 29 and the range of motion is limited, so the power-assisted sliding member 29 driven by the handle 14 can push and rotate the driving pinion 23 arranged above the sliding rail 28, the driving pinion 23 rotates the driven gearwheel 24 engaged with the driving pinion, the driven gearwheel 24 rotates the driven pinion 25 coaxial with the driven pinion to rotate the auxiliary ring 10, so the clamping mechanism shell 43 arranged at the healthy side moves along the circumferential direction driven by the auxiliary ring 10 to lift the bed sheet at the healthy side to assist the patient to turn over, at the moment, the locking rod 44 at the other side is disengaged from the locking groove 46, so the fixed plate 42 and the clamping plate 38 at the healthy side can be stretched under the action of the locking rod 44 at the other side, so that the patient can have a horizontal traction force during the turning over to keep the bed near the midline of the bed, the process has the effect of saving labor as the driving pinion 23 drives the larger driven bull gear 24;

after turning over, the patient only needs to loosen the handle 14, the bouncing of the holding plate 17 enables the ratchet arc plates 33 arranged at the two sides of the force-aid semi-ring 27 to contract, the ratchets are not engaged any more, so the force-aid sliding piece 29 returns to the original position under the action of gravity and the return spring 32, and the auxiliary ring 10 is driven by the gear to rotate reversely in the process, and finally the bed sheet is put down;

when the patient needs to turn over to the other side, the patient only needs to use the hand at the healthy side to hold the handle 14 at the sick side for the same operation.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent structures or equivalent flow transformations made by the present specification and drawings, or applied directly or indirectly to other related technical medical equipment fields, are included in the scope of the present invention.
