Description

Technical Field

[0001] The utility model relates to the technical field of fracture care, and particularly relates to a limb support nursing device with an adjustable angle. Background Technique

[0002] After the calf of a patient fractures, the fractured part needs to be reset. After resetting, the broken bone and the upper and lower two joints need to be externally fixed as a whole, so that the whole broken bone will not bend or rotate randomly, and the fracture ends will be relatively stable, further increasing the stability of the alignment and line of the broken bone, which is beneficial to the formation and healing of callus at the fracture ends.

[0003] For example, Chinese Patent CN216566259U discloses a fixed support device for leg fracture care, which includes a base. A fixing member is provided at the right end of the base. A ring body is integrally formed on the top of the base. Screw holes, sliding holes and through holes are provided on the inner side wall of the ring body. The number of both the sliding holes and the through holes is two. A screw rod is screwed in the screw hole, and a support rod is provided in the through hole. By installing a fixing member at the right end of the base and a ring body on the top of the base, a first pressing plate controlled by a screw rod is provided inside the ring body. A moving plate that moves together is provided at the top end of the screw rod. Fixed blocks with inclined surfaces are provided at the left and right ends of the bottom of the moving plate. An inclined rod is attached to the inclined plate, and a second pressing plate is installed at the bottom end of the inclined rod.

[0004] However, its technology has the following problems. The position of the patient's leg can be fixed by the first pressing plate, the second pressing plate and the inner wall of the ring body. This device fixes the patient's leg and keeps it in one position all the time. Since the patient's leg is fractured and kept in one position for a long time, it will cause leg pain and the wound edema is difficult to heal, which is not conducive to subsequent rehabilitation.

[0005] Based on this, the utility model designs a limb support nursing device with an adjustable angle to solve the above problems. Utility Model Content

The front side of the upper end of the base 31 is fixedly connected to the semi-circular plate 32, the middle of the upper end of the base 31 is fixedly connected to the worm gear 34, the semi-circular plate 32 is provided with a notch 33, and the worm gear 34 is meshed with the worm 35.

[0035] As shown in the figure, the worm gear 34 is half and fixedly installed in the middle of the upper end of the base 31.

[0036] There are two semi-circular plates 32 and notches 33, which are respectively located on the front and rear sides of the base 31.

[0037] The notch 33 is connected to the main frame 1.

[0038] The worm 35 is connected to the driving component 2.

[0039] The driving component 2 drives the worm 35 to rotate. Since the worm gear 34 is fixed on the base 31, the worm gear 34 does not rotate, but the worm 35 moves around the worm gear 34, and the worm 35 thus drives the fracture fixing plate 13 to achieve angle adjustment;

[0040] In this utility model, the angle adjustment of the fracture fixing plate 13 can be achieved through the cooperation of the worm gear 34 and the worm 35. After the patient feels uncomfortable when maintaining a certain posture for a long time, the angle of the worm 35 on the worm gear 34 can be adjusted by turning the knob 22, thereby adjusting the angle of the fracture fixing plate 13, which is beneficial to reducing the patient's pain, preventing leg edema, and facilitating the patient's recovery.

[0041] Embodiment 2

[0042] In some embodiments, as Figures 1-6 shown, as a preferred embodiment of the present utility model, there are two semi-circular plates 32 and notches 33, which are respectively located on the front and rear sides of the base 31.

[0043] The notch 33 is connected to the main frame 1.

[0044] The worm gear 35 is connected to the drive assembly 2.

[0045] The main body frame 1 includes a thigh support plate 11, a connecting shaft 12, a fracture fixing plate 13, and straps 14. The left end of the fracture fixing plate 13 is inserted into the connecting shaft 12, the connecting shaft 12 is hinged to the right end of the thigh support plate 11, multiple groups of straps 14 are symmetrically arranged and are respectively fixedly installed on the front and rear sides of the upper end of the fracture fixing plate 13, and the multiple straps 14 at corresponding positions on the front and rear sides are detachably connected.

[0046] The upper end of the fracture fixing plate 13 is provided with a placement groove that fits the calf.

[0047] The lower end of the fracture fixing plate 13 is connected to the drive assembly 2.

[0048] The front and rear sides of the lower end of the fracture fixing plate 13 are respectively slidably connected to the front and rear semi-circular plates 32.

[0049] The front and rear sides of the lower end of the fracture fixing plate 13 are both provided with bumps, and the bumps on the front and rear sides are respectively in limit sliding connection with the notches 33 on the front and rear sides.

[0050] There are various detachable connection methods between the multiple straps 14. They can be pasted by Velcro, or connected by two buckles or other locking methods.

[0051] The drive assembly 2 includes an arc-shaped notch 21, a knob 22, a connecting rod 23, and a fixing ring 24. The arc-shaped notch 21 is opened in the middle of the lower end of the fracture fixing plate 13. Two fixing rings 24 are provided and are respectively fixedly installed on the left and right sides of the arc-shaped notch 21. The left and right ends of the worm gear 35 are respectively rotatably connected to the left and right fixing rings 24. The connecting rod 23 is fixedly installed on the right side of the worm gear 35, and the right side of the connecting rod 23 is fixedly connected to the knob 22.

[0052] When the utility model is in use, place the device on the hospital bed. First, according to the patient's needs, the doctor drives the knob 22 to rotate by hand. The knob 22 drives the connecting rod 23 to rotate, and the connecting rod 23 drives the worm 35 to rotate. Then, under the action of the worm gear 34, the worm 35 starts to rotate. The worm 35 drives the fixed ring 24 to rotate, and the fixed ring 24 drives the fracture fixing plate 13 to rotate to a suitable position on the semi-circular plate 32 and the notch 33. Then, in cooperation with the position of the fracture fixing plate 13, rotate the thigh support plate 11 to a suitable position so that the left side of the thigh support plate 11 contacts the hospital bed, and the hospital bed supports the left side of the thigh support plate 11. Then, move the entire device to a position that makes the patient comfortable according to the patient's position. Finally, place the patient's thigh on the thigh support plate 11 and the patient's calf on the fracture fixing plate 13, and then fix the patient's calf with the strap 14, realizing the function of adjusting the angle of the worm 35 on the notch 33 through the knob 22, thereby adjusting the angle of the fracture fixing plate 13;

[0053] After the patient's legs have been in a certain position for a long time and feel uncomfortable, the angle of the worm 35 on the worm gear 34 can be adjusted through the knob 22, thereby adjusting the angle of the fracture fixing plate 13, and the angle of the thigh support plate 11 is adjusted accordingly, so that the patient is in a comfortable position, which is beneficial to reducing the patient's pain, preventing leg edema, and facilitating the patient's recovery.

[0057] When installing the thigh support plate 11, insert the plug rod on the right side of the thigh support plate 11 into the side of the connecting shaft 12 where the spring is installed, and then push the plug rod by hand to compress the spring, so that the plug rod on the other side of the thigh support plate 11 is installed into the other side of the connecting shaft 12. Under the action of the spring, the connecting shaft 12 fixes the thigh support plate 11;

[0058] When removing the thigh support plate 11, only need to push the plug rod by hand to compress the spring, take out the plug rod on the other side from the slot of the connecting shaft 12, and then take out the plug rod on the side of the spring.

[0059] Since the left side of the thigh support plate 11 is supported by the bed surface, the connection mode between the right side of the thigh support plate 11 and the connecting shaft 12 may not be a tight connection, and it is only necessary to ensure that the connecting shaft 12 can fix the thigh support plate 11.
