An arc-shaped groove is opened on the upper end surface of the second fixing block 19, and a latex pad is arranged at the arc-shaped groove. The arc-shaped groove on the second fixing block 19 corresponds to the arc-shaped groove on the first fixing block 14.

[0058] Since different patients have different arm lengths, the position of the fixing device cannot be adjusted according to the arm lengths of different patients.

[0059] In order to solve the above problems, this embodiment proposes an implementation method, the nursing bed also includes: a position adjustment device; the position adjustment device is arranged in the space formed inside the bed frame 1 and is fixedly connected to the moving part 10 for adjusting the position of the fixing device.

[0060] In this embodiment, Figure 4 As shown, the position adjustment device includes: a connecting plate 15 , two sets of telescopic components 16 , a cam 17 and a rotating disk 18 .

[0061] Among them, the two ends of the connecting plate 15 are fixedly connected to the two groups of moving parts 10, and the connecting plate 15 can drive the two groups of moving parts 10 to move in the same direction; the two groups of telescopic components 16 are arranged on the side of the connecting plate 15 close to the head end, and are fixedly connected to the connecting plate 15, used to limit the connecting plate 15 to only horizontal movement; the cam 17 is arranged on the side of the connecting plate 15 away from the telescopic components 16, and is tightly fitted with the connecting plate 15. When the cam 17 rotates, it will push the connecting plate 15 to move horizontally; the turntable 18 is fixedly connected to the axis of the cam 17, used to drive the cam 17 to rotate.

[0062] When the position of the fixing device needs to be adjusted, the user rotates the turntable 18, which drives the cam 17 to rotate.

[0064] Working principle:

[0065] When the nursing bed is in use, the patient is lifted onto the bed frame 1. When pressure sores are about to appear on the patient, the airbag 3 corresponding to the position of the pressure sores is found, and the lifting plate 9 is pulled upward first. The lifting plate 9 drives the latch 8 to move, so that the latch 8 is disengaged from the notch and the first spring is stretched. At this time, the pulling piece 7 is pulled outward, and the pulling piece 7 drives the piston block 6 to move. The piston block 6 will draw the gas in the corresponding airbag 3 into the air storage chamber 5 through the trachea 4, so that the airbag 3 shrinks, thereby reducing the squeezing of the patient's pressure sore position for easy use. At this time, the lifting plate 9 is released, so that the latch 8 moves downward under the action of the rebound force of the first spring, thereby inserting into the corresponding notch, realizing the restriction of the pulling piece 7, and when the patient needs to be injected During the drip, the user first rotates the turntable 18, which drives the cam 17 to rotate. The cam 17 pushes the connecting plate 15 to move toward the head of the bed. The connecting plate 15 drives the two sets of moving parts 10 to move in the same direction to adjust the position of the fixing device. Then, the patient's wrist is placed in the arc groove between the first fixing block 14 and the second fixing block 19, and the handwheel 12 is turned. The handwheel 12 drives the screw 11 to rotate, and the screw 11 moves the first fixing block 14 downward through the nut 13, so that the first fixing block 14 and the second fixing block 19 cooperate to fix the patient's arm to prevent the patient from moving and the needle from rolling. It will not cause damage to the user's arm, and the use of this nursing bed is completed.
