For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] The following is combined with Figure 1-5 The utility model is further described.

[0030] In order to solve the technical problems in the background technology, the present application provides: a lower limb lifting pad, including a fixed pad 2 and an anti-slip base plate 1, a telescopic rod 3 is fixedly connected between the upper surface of the anti-slip base plate 1 and the corner of the bottom surface of the fixed pad 2, and a lifting mechanism is arranged between both sides of the upper surface of the anti-slip base plate 1 and the bottom surface of the fixed pad 2; when the anti-slip base plate 1 is placed on the bed, the device is fixed on the bed by utilizing the anti-slip property of the bottom of the anti-slip base plate 1, and the telescopic rod 3 arranged at the corner of the bottom surface of the fixed pad 2 limits the moving direction of the fixed pad 2, so that the fixed pad 2 can only be lifted and lowered relative to the anti-slip base plate 1, and the purpose of setting the lifting mechanism is to use the lifting mechanism to drive the fixed pad 2 to lift and lower under the premise that the telescopic rod 3 limits the moving direction of the fixed pad 2, so as to achieve support of the patient's lower limbs at different heights.

[0031] In a further design, the lifting mechanism is mainly composed of two sliders 20 embedded and plugged into the upper surface of the anti-skid bottom plate 1, and a connecting arm 12 rotatably connected to the upper surface of the slider 20. The side of the connecting arm 12 away from the slider 20 is rotatably connected to the ground of the fixed pad 2. A two-way screw rod 9 rotatably connected to the anti-skid bottom plate 1 is threaded through the two sliders 20. A transmission member 13 for driving the two two-way screw rods 9 to rotate synchronously is provided between the two two-way screw rods 9 on the anti-skid bottom plate 1. The two sliders 20 are symmetrically distributed about the middle position of the two-way screw rod 9 on the anti-skid bottom plate 1. Therefore, by rotating the two-way screw rod 9 on the anti-skid bottom plate 1, the slider 20 When embedded in the anti-slip base plate 1, the two sliders 20 approach or move away from each other as the bidirectional screw rod 9 on the anti-slip base plate 1 rotates forward and reversely, and the other end of the connecting arm 12 on the slider 20 is rotatably connected to the bottom edge of the fixed pad 2. Therefore, the distance between the fixed pad 2 and the anti-slip base plate 1 increases as the two sliders 20 approach each other, and decreases as the two sliders 20 move away from each other. The additional transmission member 13 is specifically two sprockets respectively fixed to the two bidirectional screw rods 9 on the anti-slip base plate 1 and a chain meshing with the sprockets, so that when one of the bidirectional screw rods 9 on the anti-slip base plate 1 is rotated, the other bidirectional screw rod 9 is driven to rotate.

[0032] In a further design, two connecting blocks 10 are symmetrically plugged into the bottom surface of the fixed pad 2, and a soft bag clamping block 4 for clamping the upper and lower limbs of the fixed pad 2 is fixedly connected to the connecting block 10. The bottom surface of the fixed pad 2 is also rotatably connected with a bidirectional screw rod 9, and the bidirectional screw rod 9 on the fixed pad 2 is threadedly penetrated by the two connecting blocks 10. Similarly, the connecting blocks 10 are symmetrically distributed about the bidirectional screw rod 9 on the fixed pad 2. Therefore, by rotating the bidirectional screw rod 9 on the fixed pad 2, the two connecting blocks 10 can drive the corresponding soft bag clamping blocks 4 to move away from or approach each other, thereby clamping the lower limbs of different sizes on the fixed pad 2.

[0033] In a further design, one of the soft bag clamping blocks 4 is fixedly connected to a limiting rack 6 on the back, and a sliding seat 15 sliding along the length direction of the limiting rack 6 is inserted on the back of the same soft bag clamping block 4, one end of the sliding seat 15 is rotatably connected to a bevel gear plate 14, and a screw rod 7 is threadedly connected to the end face of the bevel gear plate 14, and one end of the screw 7 is connected to a sling 8 for suspending the lower limbs. The side of the soft bag clamping block 4 facing the lower limb is a soft bag setting, and the side away from the lower limb is a hard plate setting. When in use, the screw rod 7 is driven by the sliding seat 15 to slide a certain distance along the length direction of the limiting rack 6, and then the lower limb is wrapped around one end of the sling 8. By rotating the screw rod 7, the screw rod 7 is raised and lowered for a certain distance, or the screw rod 7 is driven to tilt and swing by the bevel gear plate 14, the patient's lower limb can be suspended in the air using the sling 8, which is convenient for personnel to wipe the patient's lower limbs and for changing dressings.

[0034] In a further design, a motor 16 is plugged into the slide 15 and slides relative to the bevel gear plate 14. The main shaft of the motor 16 is fixedly connected to a roller 18 for rolling connection with the back of the soft bag clamp block 4. The end face of the roller 18 is fixedly connected to a bevel gear block 17 for meshing with the bevel gear plate 14. Because the diameter of the roller 18 is larger than the bevel gear block 17, and the installation height of the roller 18 is misaligned with the bevel gear plate 14, when the motor 16 drives the roller 18 and the bevel gear block 17 to rotate and the bevel gear block 17 is meshed with the bevel gear plate 14, the roller 18 is rotated. 8 will not contact the bevel gear plate 14, but drive the bevel gear plate 14 to rotate through the bevel gear block 17, thereby realizing the tilting and swinging of the screw rod 7. When the sling 8 is wrapped around the patient's lower limbs, the patient's lower limbs are lifted. Similarly, when the roller 18 moves with the motor 16 to contact the back of the soft bag clamping block 4, the side of the bevel gear block 17 does not contact the back of the soft bag clamping block 4. The slide seat 15 is fixedly connected with an electric push rod 19 for driving the motor 16 to move. Therefore, when the motor 16 housing and the slide seat 15 are plugged in, the electric push rod 19 can be extended and retracted to drive the The motor 16 moves, and two positioning racks 11 are arranged at the bottom of the slide 15, and a gear 5 is rotatably connected with the gears 5 meshing with the tooth surfaces of the two positioning racks 11. The two positioning racks 11 are respectively fixedly connected to the motor 16 housing and plugged into the bottom of the slide 15, and the positioning racks 11 plugged into the slide 15 are arranged in an L shape, and one end of the L-shaped positioning rack 11 is used to mesh with the limit rack 6. Therefore, when the bevel gear block 17 is meshed with the bevel gear plate 14, one side of the L-shaped positioning rack 11 is in meshing state with the limit rack 6, and The L-shaped positioning rack 11 is plugged into the bottom edge of the slide 15, so the relative position of the slide 15 and the limiting rack 6 can be fixed, thereby fixing the position of the screw 7. When the motor 16 moves toward the soft bag clamp 4, the positioning rack 11 connected to the motor 16 moves synchronously, and drives the gear 5 to rotate, thereby realizing that the other L-shaped positioning rack 11 moves to disengage from the limiting rack 6, so that when the roller 18 rolls on the soft bag clamp 4, the slide 15 is moved on the soft bag clamp 4, thereby adjusting the position of the screw 7.

[0035] In order for those skilled in the art to fully understand the technical solution, this embodiment is summarized as follows:

[0036] When in use, the anti-slip base plate 1 is placed on the bed, and when the roller 18 on the main shaft of the motor 16 contacts the back of the soft bag clamping block 4 under the pushing action of the electric push rod 19, the L-shaped positioning rack 11 disengages from the limiting rack 6, and at this time, the motor 16 drives the roller 18 to roll on the soft bag clamping block 4, thereby realizing that the slide seat 15 drives the screw 7 to move to one end of the soft bag clamping block 4, and then under the telescopic action of the electric push rod 19, the motor 16 is pushed away from the soft bag clamping block 4 again, and the bevel gear block 17 is meshed with the bevel gear plate 14 again, and the patient's lower limbs are wrapped with the sling 8, and then the bevel gear block 17 is meshed with the bevel gear plate 14, and the motor 16 drives the roller 18 and the bevel gear block 17 to rotate, thereby realizing that the bevel gear plate 14 drives the screw 7 to tilt and swing, and the screw 7 and During the upward swinging of one end of the sling 8, the sling 8 is used to lift the patient's lower limb to a height higher than the fixing pad 2, and then the motor 16 is brought toward the soft bag clamp 4 again under the contraction action of the electric push rod 19 until the roller 18 contacts the surface of the soft bag clamp 4 again, and then the roller 18 is rotated to drive the slide 15 to the other end of the soft bag clamp 4, and under the traction action of the sling 8, the anti-slip base plate 1 drives the fixing pad 2 to move under the patient's lower limb, and then the angle of the screw 7 is adjusted so that the lower limb is placed on the fixing pad 2, and the bidirectional screw 9 on the anti-slip base plate 1 is rotated to make the two sliders 20 approach each other. Under the connecting action of the connecting arm 12, the distance between the fixing pad 2 and the anti-slip base plate 1 increases as the two sliders 20 approach each other, thereby raising the patient's lower limb.

[0037] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
