Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a multi-angle adjustable postoperative lifting device. Background Art

[0002] Positioning cushions are important auxiliary tools used in medical care to help patients maintain a specific position, improve comfort, and prevent complications. They are widely used in operating rooms, ICUs, rehabilitation departments, and home care. They can be divided into sponge positioning cushions, gel positioning cushions, memory foam positioning cushions, and inflatable positioning cushions according to their materials. They can be divided into surgical positioning cushions, rehabilitation positioning cushions, and pressure ulcer prevention cushions according to their uses.

[0003] During postoperative rehabilitation care for patients, corresponding lifting devices, namely positioning cushions, are needed to assist in the patient's rehabilitation treatment. However, the existing positioning cushions still have shortcomings in actual use. Most of the existing traditional positioning cushions adopt a fixed structural design, so that the inclination angle of the positioning cushion is fixed. The patient's limbs can only be lifted to a fixed angle with the support of the positioning cushion. This fixed angle design will easily cause the patient's venous valves to be continuously compressed, thereby affecting blood flow. Therefore, this needs to be improved. Summary of the Invention

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1 to 7 As shown, the embodiment of the present invention provides a multi-angle adjustable postoperative lifting device, including a base 1, a fixed shaft 2 is fixedly sleeved on the left side of the top end of the base 1, a connecting block 3 is movably sleeved in the middle of the outer surface of the fixed shaft 2, a bottom plate 4 is fixedly installed on the top of the connecting block 3, the bottom end of the bottom plate 4 is movably connected to the top of the base 1, a sponge pad 5 is fixedly installed on the top of the bottom plate 4, an oblique rod 6 is hinged in the middle of the bottom end of the bottom plate 4, and a movable block 7 is hinged at the other end of the oblique rod 6, the outer surface of the movable block 7 is movably sleeved on the right side of the bottom of the inner surface of the base 1, and the middle end of the movable block 7 A threaded rod 8 is sleeved on the internal thread. The left end of the threaded rod 8 passes through the base 1 and extends to the left end of the base 1 and is fixedly sleeved with a stopper 9. The outer surface of the stopper 9 is movably sleeved with the inner surface of the left end of the base 1. The right end of the threaded rod 8 passes through the base 1 and extends to the outside of the base 1 and is fixedly sleeved with a first handle 10. A gear 11 is fixedly sleeved on the right side of the outer surface of the threaded rod 8. The left end of the gear 11 is movably connected to the right end of the base 1. The interior of the front and rear ends of the movable block 7 are respectively movably sleeved with a limit rod 12, and the outer surface of the limit rod 12 is fixedly sleeved with the inner surface of the base 1.

[0028] When the first handle 10 is rotated, the threaded rod 8 will rotate. Since the threaded rod 8 and the movable block 7 are threadedly connected, the movable block 7 will move along the outer surface of the limit rod 12 with the inclined rod 6 under the action of the threaded rod 8, so that the other end of the inclined rod 6 generates a thrust on the base plate 4, pushing the base plate 4 to rotate with the sponge pad 5 and the connecting block 3 around the fixed axis 2. At the same time, the mutual cooperation between the stop block 9 and the gear 11 will ensure the rotation stability of the threaded rod 8, thereby realizing the adjustment of the angle of the base plate 4 and the sponge pad 5, thereby achieving the purpose of step-by-step posture management, preventing the patient's limbs from being raised at a fixed angle, causing the patient's venous valves to be continuously compressed, affecting blood flow.

[0029] Among them, a vertical plate 13 is fixedly installed in the middle of the front end of the base 1, the rear end of the vertical plate 13 is movably connected to the front end of the bottom plate 4, and an indicator rod 14 is movably sleeved inside the front end of the vertical plate 13. There are three indicator rods 14 and they are all the same in shape and size.

[0030] The three indicator rods 14 correspond to 20°, 30° and 45° from bottom to top. By blocking the base plate 4 respectively, the three indicator rods 14 can indicate when the base plate 4 rotates 20°, 30° and 45°, thereby improving the accuracy of the angle adjustment of the base plate 4 and preventing the base plate 4 from rotating too much or too low.

[0031] Among them, the rear sides of the outer surfaces of the three indicator rods 14 are fixedly sleeved with square plates 15, the outer surfaces of the square plates 15 are movably sleeved with the inner surfaces of the vertical plates 13, and the front ends of the square plates 15 are fixedly installed with a first spring 16 located outside the indicator rods 14, and the other ends of the first springs 16 are fixedly connected to the inner surfaces of the vertical plates 13.

[0032] The first spring 16 is in a compressed state. Under the restoring action of the first spring 16 , the square plate 15 will move the indicator rod 14 toward the sponge pad 5 , so that the indicator rod 14 moves to the outside of the vertical plate 13 .

[0033] Among them, the front ends of the three indicator rods 14 are respectively fixedly installed with round shafts 17, the outer surface of the round shaft 17 is movably sleeved with a rotating block 18, the rear end of the rotating block 18 is movably connected to the front end of the vertical plate 13, and the top of the front end of the rotating block 18 is fixedly installed with a paddle 19.

[0034] When the paddle 19 is turned, the rotating block 18 will rotate around the circular shaft 17 as the axis, so that the circular shaft 17, the indicator rod 14 and the square plate 15 will move backward under the restoring action of the first spring 16.

[0035] Among them, the front and rear sides of the middle part of the right end of the base 1 are movably connected with clamping rods 20 respectively. The number of the clamping rods 20 is two, and the bottoms of the opposite surfaces of the two clamping rods 20 are fixedly installed with rubber pads 21 respectively.

[0036] When the two clamping rods 20 respectively carry the rubber pads 21 and move toward the gear 11 , the rotation position of the gear 11 can be locked, thereby preventing the gear 11 from rotating unexpectedly.

[0037] Among them, the inner surfaces of the bottom ends of the two clamping rods 20 are movably connected with square rods 22, and the front and rear ends of the outer surfaces of the square rods 22 are fixedly connected with first support blocks 23 respectively, and the left end of the first support block 23 is fixedly connected to the right end of the base 1.

[0038] The outer surface of the square rod 22 and the inner surface of the clamping rod 20 are both smooth, thereby ensuring that the clamping rod 20 will not get stuck when moving along the outer surface of the square rod 22. At the same time, the mutual cooperation between the square rod 22 and the first support block 23 will ensure the stability of the movement of the clamping rod 20 and prevent the clamping rod 20 from detaching and falling.

[0039] Among them, the inner surfaces of the middle ends of the two clamping rods 20 are movably connected with a round rod 24, and the front and rear ends of the outer surface of the round rod 24 are respectively fixedly connected with a second support block 25, the left end of the second support block 25 is fixedly connected to the right end of the base 1, and the opposite surfaces of the two clamping rods 20 are fixedly installed with a second spring 26 located outside the round rod 24.

[0040] The second spring 26 is in a stretched state. Under the restoring action of the second spring 26 , when the two clamping rods 20 are no longer supported, they will move toward each other along the outer surfaces of the round rod 24 and the square rod 22 , thereby clamping the gear 11 through the mutual cooperation between the clamping rod 20 and the rubber pad 21 .

[0041] Among them, a movable shaft 27 is movably sleeved on the top middle part of the right end of the base 1, and an elliptical block 28 is fixedly sleeved on the right side of the outer surface of the movable shaft 27. The outer surface of the elliptical block 28 is movably connected to the outer surface of the base 1, and the front and rear ends of the elliptical block 28 are movably connected to the opposite surfaces of the two clamping rods 20 respectively.

[0042] When the elliptical block 28 rotates around the movable shaft 27 , the elliptical block 28 will no longer support the clamping rod 20 . At this time, the two clamping rods 20 will respectively move toward each other with the rubber pads 21 under the restoring action of the second spring 26 .

[0043] The left end of the outer surface of the movable shaft 27 is fixedly sleeved with a circular plate 29 , the right end of the circular plate 29 is movably connected to the right inner wall of the base 1 , and the right end of the outer surface of the movable shaft 27 is fixedly sleeved with a second handle 30 .

[0044] When the second handle 30 is rotated, the second handle 30 will rotate with the elliptical block 28 through the movable shaft 27, so that the elliptical block 28 no longer supports the clamping rod 20. The presence of the circular plate 29 can ensure the stability of the rotation of the movable shaft 27 and prevent the movable shaft 27 from detaching from the base 1.

[0045] Working principle and usage process:

[0046] During use, the operator moves the paddle 19 at the bottom of the vertical plate 13 within any 4-hour period of 6-24 hours after the operation, so that the rotating block 18 rotates around the circular shaft 17 as the axis. Since the first spring 16 is in a compressed state, under the restoring action of the first spring 16, the square plate 15 will move with the circular shaft 17 through the indicator rod 14 until the rotating block 18 rotates ninety degrees. At this time, the rotating block 18 will be blocked and the indicator rod 14 will also move to the outside of the vertical plate 13, so that the rotation angle of the bottom plate 4 can be indicated by the indicator rod 14.

[0047] Then the operator turns the first handle 10 to rotate the threaded rod 8, so that the movable block 7 threadedly sleeved on the outer surface of the threaded rod 8 moves along the outer surface of the limit rod 12 with the bottom end of the inclined rod 6, and then the other end of the inclined rod 6 generates a thrust on the base plate 4, pushing the base plate 4 to rotate with the connecting block 3 and the sponge pad 5 around the fixed axis 2 until the base plate 4 contacts the indicator rod 14 protruding from the bottom of the vertical plate 13. At this time, the rotation angle of the base plate 4 is 20°, and then the patient can place the limb inside the sponge pad 5 and maintain this angle for 4 hours, thereby reducing the resistance to lymphatic return.

[0048] At the same time, in order to prevent the angle of the base plate 4 from changing due to accidental rotation of the threaded rod 8, the operator rotates the second handle 30 after adjusting the angle of the base plate 4, so that the second handle 30 rotates with the elliptical block 28 through the movable shaft 27, so that the elliptical block 28 no longer supports the clamping rod 20. At this time, under the recovery action of the second spring 26, the clamping rod 20 will move toward each other along the outer surfaces of the square rod 22 and the round rod 24 with the rubber pad 21, thereby clamping and fixing the gear 11, thereby locking the rotation position of the gear 11 and the threaded rod 8. Within 24-48 hours after surgery and 48 hours after surgery, repeat the above steps to rotate the base plate 4 to 30° and 45° respectively, thereby promoting the opening of the venous valve within 24-48 hours after surgery, and enhancing the muscle pump effect 48 hours after surgery, thereby realizing step-by-step posture management.
