[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] like Figures 1 to 5 As shown, the utility model provides a medical height-adjustable orthopedic care lifting pad, comprising a main body base 1, a slide groove 5 is provided in the middle of the main body base 1,
[0028] Screws 45 are rotatably provided at both ends of the slide groove 5, one end of the screw 45 movably passes through the side wall of the main base 1 and extends to the outside, and is fixedly connected to a rotating handle 46 on the side wall of the main base 1. The rotating handle 46 is pushed to control the rotation of the screw 45. It is worth mentioning that the surface of the part of the screw 45 that passes through the main base 1 is smooth to prevent the screw 45 from being unable to rotate.
[0029] The surface thread of the screw 45 is provided with a sliding seat 44, and the middle part of the sliding seat 44 is provided with an internal threaded hole threadedly connected to the screw 45. The sliding seat 44 is moved along the slide groove 5 by rotating the screw 45, thereby providing power for the lifting mechanism 4. A rotating seat 43 is welded and fixed on the upper end face of the sliding seat 44 to transmit the thrust received by the sliding seat 44. A force plate 42 is provided in the middle part of the rotating seat 43, and a rotating shaft is movably inserted between the rotating seat 43 and the force plate 42. The middle part of the rotating shaft is smooth and the smooth surface contacts the through hole of the force plate 42. The end of the force plate 42 away from the rotating seat 43 is fixedly connected to the U-shaped bracket 41. The force plate 42 is subjected to the thrust transmitted by the rotating seat 43 and applied to the end connected to the U-shaped bracket 41. The end of the U-shaped bracket 41 is fixedly connected to the body mechanism 3.
[0030] The body mechanism 3 includes a rotating rod 33 rotatably connected to both sides of the main body base 1 by using a half-thread screw 7. The tops of the two rotating rods 33 are rotatably connected to the second connecting plates 32 by using a half-thread screw 7. The two second connecting plates 32 are I-shaped, and the side close to the lifting mechanism 4 is rotatably connected to the second connecting bracket 34 by using a half-thread screw 7. The other end of the second connecting bracket 34 is connected to the U-shaped bracket 41.
[0031] It is worth mentioning that Figure 4 As shown, the U-shaped bracket 41 has holes at both ends connected to the second connecting bracket 34, and a half-thread screw 7 is rotatably connected in the hole. One end of the half-thread screw 7 extends out of the hole of the second connecting bracket 34 to leave a certain space, and the end is welded and fixed to the U-shaped bracket 41, thereby increasing the interval between the second connecting bracket 34 and the U-shaped bracket 41 to prevent interference caused by contact during operation;
[0032] like Figure 3 As shown, the two second connecting plates 32 are rotatably connected to the first connecting bracket 31 using half-thread screws 7 on one side away from the lifting mechanism 4. The second connecting plate 32 is connected to the first connecting bracket 31 and the second connecting bracket 34 at both ends to form stability. At the same time, the second connecting plate 32 and the rotating rod 33 are rotatably arranged to cooperate with the thrust of the lifting mechanism 4 to lift and lower the second connecting bracket 34.
[0033] The lower limb mechanism 2 includes an electric push rod 21 fixed in the cavities on both sides of the main body base 1. The telescopic ends of the two electric push rods 21 are movable through the side wall of the main body base 1 and are threadedly fixed to one end of the arc-shaped bracket 22, which pushes the arc-shaped bracket 22 laterally and provides stability as a support point. The other ends of the two arc-shaped brackets 22 are rotatably connected to the first connecting plate 23 using a half-thread screw 7, and the other ends of the two first connecting plates 23 are rotatably connected to the force-bearing bracket 24 using a half-thread screw 7, so that the lateral thrust received by the arc-shaped bracket 22 is converted into a longitudinal thrust, thereby lifting the force-bearing bracket 24. At the same time, the force-bearing bracket 24 is curved in an arc shape and can be used to place the patient's feet.
[0034] Specifically, Figure 1 A layer of rubber bandage 6 is provided between the two first connecting brackets 31 to cover the patient's lower limbs below the buttocks, and a layer of rubber bandage 6 is provided on the surface of the second connecting bracket 34 to cover the patient's torso from the head to the buttocks, and the width of the rubber bandage 6 on the surface of the second connecting bracket 34 must be greater than the rubber band 6 between the two first connecting brackets 31 to facilitate the patient to lie down.
[0035] Specifically, the semi-thread screws 7 mentioned above are all fixed with nuts at their external threads to maintain stability (this installation method is existing and conventional, and the specific connection method will not be repeated). (Except for the semi-thread screws 7 used to connect the second connecting bracket 34 and the U-shaped bracket 41).
[0036] Principle and process of this utility model:
[0037] When using the device, the device is in a horizontal state by default. When the patient is placed on the platform and the corresponding limb part is on the corresponding mechanism platform, the medical staff can twist the handle 46 to rotate the lead screw 45 according to the patient's condition, thereby moving the sliding seat 44 to the left (the sliding seat 44 is located at the rightmost side of the slide slot 5 by default). Figure 1 As shown in the figure), the movement of the sliding seat 44 drives the rotating seat 43 above to move synchronously, so that the force-bearing plate 42 rotates around the middle of the rotating seat 43, thereby applying a leftward thrust to the U-shaped bracket 41. The U-shaped bracket 41 pushes the second connecting bracket 34, and the second connecting bracket 34 is connected to the second connecting plate 32 through rotation, forming an overall leftward thrust and an upward thrust at the right end.
[0038] At the same time, the second connecting plate 32 and the rotating rod 33 rotate with each other, and the bottom of the rotating rod 33 is rotatably connected to the main base 1. When the second connecting plate 32 receives the left thrust transmitted by the second connecting bracket 34, the second connecting plate 32 rotates counterclockwise around the connection point with the rotating rod 33, thereby raising the left end of the second connecting bracket 34. At this time, the second connecting bracket 34 is raised as a whole, thereby raising the patient's body part to a suitable height, allowing medical staff to perform relevant care.
[0039] The microcomputer controls the controller through the wires, and the controller powers on the electric push rod 21 through the wires to start the electric push rod 21, so that the telescopic end of the electric push rod 21 extends, thereby applying a leftward thrust to the arc-shaped bracket 22. The arc-shaped bracket 22 is rotatably connected to the first connecting plate 23 at the top, thereby transmitting a leftward thrust to the first connecting plate 23. At this time, the first connecting plate 23 is rotatably connected to the force-bearing bracket 24, and the right end of the force-bearing bracket 24 is fixedly connected to the first connecting bracket 31 and is not affected by the rotation, resulting in an interaction force, so that the first connecting plate 23 converts the leftward thrust into an upward thrust and transmits it to the force-bearing bracket 24. At this time, the force-bearing bracket 24 is in a state of left end being raised;
[0040] Because the right end of the force-bearing bracket 24 is connected to the first connecting bracket 31, when the left end of the force-bearing bracket 24 is lifted, a rightward thrust will be applied to the first connecting bracket 31, and the first connecting bracket 31 is rotatably connected to the second connecting plate 32, so that the first connecting bracket 31 transmits the rightward thrust received to the second connecting plate 32, and the second connecting plate 32 rotates clockwise to lift the right end of the first connecting bracket 31. At this time, the first connecting bracket 31 is lifted in an overall horizontal manner, thereby lifting the patient's lower limbs to a suitable position, avoiding the tilt caused by lifting one end and causing the displacement of the affected limb, which is convenient for medical staff to carry out care, and combined with the function of lifting the upper limbs, it can be applied to a wider range of patients.
