Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an auxiliary support for patients with lower limb fractures to facilitate dressing changes. Background Technology

[0002] In clinical practice, dressing changes for fractures are a common procedure in orthopedics. When changing dressings for patients with lower limb fractures, the patient lies on the hospital bed, and medical staff need to lift the injured limb and use a pad to maintain the height. However, the stability of the pad is poor, and over time, it can cause the injured limb to twist, leading to increased pain. At the same time, the injured limb is only raised, and the knee flexion angle cannot be adjusted, resulting in poor comfort. Therefore, we propose an auxiliary support that is convenient for patients with lower limb fractures to use during dressing changes to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide an auxiliary support for patients with lower limb fractures to facilitate dressing changes, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary support for patients with lower limb fractures to use during dressing changes, comprising a base plate, one end of which is rotatably connected to a fixed hinge shaft, both sides of which are hinged to one end of a movable connecting rod, the other ends of which are rotatably connected to both ends of the movable connecting rod, both sides of which are hinged to one end of an upper connecting rod, the other ends of which are rotatably connected to both ends of a support shaft, a connecting seat fixedly connected to the middle of the support shaft, one end of which is fixedly connected to one end of a threaded rod, the other end of which is sleeved on one end of an internal threaded cylinder through a threaded structure, the other end of which is rotatably connected to a locking block, the locking block engaging with a locking groove, the locking groove being recessed in the middle of the top surface of the base plate;

[0005] The base plate has sliding openings on both sides, and an adjustment seat is slidably arranged in the sliding openings. One end of the adjustment seat is hinged to one end of the support rod, and the other end of the support rod is hinged to one side of the movable rod. The other end of the adjustment seat is connected to a threaded knob through a threaded structure, and the threaded knob abuts against the outer wall of the base plate.

[0006] Preferably, several support plates are fixedly connected between the movable connecting rods, and several support plates are also fixedly connected between the upper connecting rods, with the support plates evenly distributed.

[0007] Preferably, the sliding groove has a T-shaped structure.

[0008] Preferably, the support links are arranged symmetrically in parallel.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the adjustment seat drives the support link to move, the support link drives the movable link to swing around the fixed hinge axis, and the movable link can then be raised to a suitable height according to the height requirements of leg dressing changes. Through the cooperation of the threaded rod and the internal threaded cylinder, the upper link is supported, keeping the upper link horizontal. The support plate fixed between the upper links supports the patient's lower limbs, ensuring the stability of the support. By adjusting the angle between the upper link and the movable link, the patient's knee can be bent, avoiding the patient's knee being in a straight state for a long time, thus improving the patient's comfort.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example 1

[0015] Reference Figure 1 , 2 This is the first embodiment of the present invention. This embodiment provides an auxiliary support for patients with lower limb fractures to change dressings. It includes a base plate 1. One end of the base plate 1 is rotatably connected to a fixed hinge shaft 2. The two sides of the fixed hinge shaft 2 are respectively hinged to one end of a movable connecting rod 3. The other end of the movable connecting rod 3 is respectively rotatably connected to both ends of a movable hinge shaft 5. The two sides of the movable hinge shaft 5 are respectively hinged to one end of an upper connecting rod 6. The other end of the upper connecting rod 6 is respectively rotatably connected to both ends of a support shaft 7. The middle part of the support shaft 7 is fixedly connected to a connecting seat 8. One end of the connecting seat 8 is fixedly connected to one end of a threaded rod 9. The other end of the threaded rod 9 is sleeved with one end of an internal threaded cylinder 10 through a threaded structure. The other end of the internal threaded cylinder 10 is rotatably connected to a locking block 11. The locking block 11 is engaged with a locking groove 12. The locking groove 12 is recessed in the middle of the top surface of the base plate 1.

[0016] The base plate 1 has sliding openings 13 on both sides, and an adjustment seat 15 is slidably arranged in the sliding openings 13. One end of the adjustment seat 15 is hinged to one end of the support rod 4, and the other end of the support rod 4 is hinged to one side of the movable rod 3. The other end of the adjustment seat 15 is connected to the threaded knob 14 through a threaded structure. The threaded knob 14 abuts against the outer wall of the base plate 1.

[0017] Medical staff manually loosen the threaded knob 14, disengaging it from the outer wall of the base plate 1. This allows them to move the adjusting seat 15, which moves within the sliding opening 13 towards the fixed hinge shaft 2. The movement of the adjusting seat 15 causes the hinged support rod 4 to swing, which in turn causes the movable connecting rod 3 to swing around the fixed hinge shaft 2. The movable connecting rod 3 then raises one end of the movable hinge shaft 5. Once raised to the appropriate height, the adjusting seat 15 stops. Then, the threaded knob 14 is manually tightened, pressing against the outer wall of the base plate 1. Friction then keeps the adjusting seat 15 in a fixed position. When the limb requiring dressing needs to be placed horizontally, the upper connecting rod 6 is manually operated to swing to a horizontal position. The inner threaded cylinder 10 is then rotated, adjusting the length of the inner threaded cylinder 10 and the threaded rod 9 through the threaded structure. This allows the inner threaded cylinder 10 and the threaded rod 9 to form a horizontal structure. The vertical structure, with the locking block 11 engaging in the slot 12, fixes the positions of the internal threaded cylinder 10 and the threaded rod 9. Simultaneously, the internal threaded cylinder 10 and the threaded rod 9, in conjunction with the connecting seat 8, support the movable hinge shaft 5 of the upper connecting rod 6, keeping the upper connecting rod 6 horizontal. The limb requiring dressing changes is supported on the support plate 16, ensuring stability during dressing changes. When the patient's knee needs to bend, the patient's thigh is supported by the support plate 16 fixed to the movable connecting rod 3, with the knee positioned at the movable hinge shaft 5. Then, based on the patient's bending angle, the upper connecting rod 6 is adjusted to a suitable tilt angle. The lengths of the threaded rod 9 and the internal threaded cylinder 10 are then adjusted, and the tilt angle of the upper connecting rod 6 is fixed through the engagement of the locking block 11 and the slot 12. The patient's lower leg is supported by the support plate 16 fixed to the upper connecting rod 16, further improving the comfort of the patient's knee position.

[0018] Example 2

[0019] Reference Figure 1-2 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, several support plates 16 are fixedly connected between the movable connecting rods 3 and several support plates 16 are also fixedly connected between the upper connecting rods 6. The support plates 16 are evenly distributed, which facilitates the support plates 16 to support the patient's limbs.

[0020] Specifically, the sliding opening 13 has a T-shaped structure, and several slots 12 are evenly distributed along the length of the base plate 1. Thus, when the upper connecting rod 6 is adjusted to different angles, the slots 12 can still engage with the block 11.

[0021] Specifically, the support links 4 are arranged in a parallel and symmetrical manner, which allows the support links 4 to provide stable support for the movable link 3.

[0022] Example 3

[0023] Reference Figure 1-2 This is the third embodiment of the present invention. Based on the above two embodiments, in use, medical personnel manually loosen the threaded knob 14, causing it to disengage from the outer wall of the base plate 1. This allows the adjusting seat 15 to be moved. The adjusting seat 15 moves within the sliding opening 13 towards the fixed hinge shaft 2. After moving, the adjusting seat 15 drives the hinged support rod 4 to swing. The support rod 4 then drives the hinged movable connecting rod 3 to swing around the fixed hinge shaft 2. The movable connecting rod 3 further causes the movable hinge shaft 5 to... One end is raised, and when it reaches the appropriate height, the adjusting seat 15 stops. Then, the threaded knob 14 is manually tightened, and the threaded knob 14 abuts against the outer wall of the base plate 1, thereby keeping the adjusting seat 15 fixed in position through friction. When the limb to be dressed needs to be placed horizontally, the upper connecting rod 6 is manually operated to swing the upper connecting rod 6 to the horizontal structure. Then, the inner threaded cylinder 10 is rotated to adjust the length of the inner threaded cylinder 10 and the threaded rod 9 through the thread structure, so that the inner threaded cylinder 10 and the threaded rod 9 are in a vertical structure, and the locking block 11 locks them in place. The internal threaded cylinder 10 and threaded rod 9 are fixed in the slot 12. Simultaneously, the internal threaded cylinder 10 and threaded rod 9, in conjunction with the connecting seat 8, support the movable hinge shaft 5 of the upper connecting rod 6, keeping the upper connecting rod 6 horizontal. The limb requiring dressing changes is supported on the support plate 16, ensuring stability during dressing changes. When the patient's knee needs to bend, the patient's thigh is supported by the support plate 16 fixed to the movable connecting rod 3, with the knee positioned at the movable hinge shaft 5. Then, according to the patient's bending angle, the upper connecting rod 6 is adjusted to a suitable tilt angle. The lengths of the threaded rod 9 and internal threaded cylinder 10 are then adjusted. Through the engagement of the locking block 11 and the slot 12, a damping shaft can be set at the rotatable connection point of the support shaft 7 and the upper connecting rod 6, providing resistance at the rotatable connection point and preventing changes in the tilt angle of the upper connecting rod 6 during support, thus maintaining a fixed tilt angle. The patient's lower leg is supported by the support plate 16 fixed to the upper connecting rod 16, further improving the comfort of the patient's knee position.

[0024] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial improvements made to this utility model using this concept should be considered as infringing on the protection scope of this utility model.
