Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical devices, and particularly relates to a leg elevation device. Background Art
[0002] For patients with lower limb fractures such as femoral shaft fractures, distal femoral fractures, patellar fractures, tibiofibular fractures, etc., after the fracture, the affected limb is prone to swelling. It is necessary to elevate the affected limb to facilitate the venous return of the lower limb, thereby accelerating the detumescence process. In addition, during preoperative tibial tubercle traction and supracondylar femoral traction treatment, the affected limb needs to be placed in a flexed position, and it is necessary to assist the patient for support. During the postoperative exercise process, due to pain, patients with lower limb fractures cannot actively perform functional exercises, so extension joint stiffness often occurs, and the flexion activity is severely limited. Elevating the affected limb and changing the position of the baffle can assist in passive flexion activities of the knee joint, enabling the patient to intuitively see the angle of each activity. When the affected limb can actively flex to a certain angle, calf elevation activities can be exercised at this angle, thereby promoting the recovery of quadriceps femoris muscle strength. For patients after femoral neck fracture surgery, hip muscle group activities should be avoided in the early stage, and the knee joint needs to be placed at a flexed angle to exercise the contraction activity of the quadriceps femoris.
[0003] Existing elevation pads: all are solid sponge pads filled. Disadvantages: large volume, inconvenient to store; only have the function of elevating the affected limb; the knee joint angle is fixed and cannot be adjusted; the slope length is fixed, and there are significant differences in comfort for patients with different heights.
[0004] The improved elevation pad: is a frame combination, occupies a small space after storage, and is convenient for recycling and transfer; has multiple combined functions, can not only elevate the affected limb to detumesce, but also assist in postoperative knee joint function exercise; the length of the thigh part can be adjusted to increase the comfort experience of patients with different heights; the dial can intuitively show the knee joint flexion angle, directly reflecting the postoperative function exercise effect of the affected limb; the angle at the knee joint can be adjusted to avoid knee joint stiffness caused by maintaining a fixed angle for a long time.

Specific embodiments
[0035] Embodiment 1:
[0036] Referring to Figure 1-2 , it is a schematic diagram of the structure of Embodiment 1 of the present utility model. A leg elevation device includes:
[0037] Lower backing plate 1;
[0038] Thigh backing plate 2, one end of which is hinged to one end of the lower backing plate 1;
[0039] Calf backing plate 3, one end of which is hinged to the other end of the thigh backing plate 2;
[0040] A plurality of second limiting ribs 102 are equidistantly arranged on the upper surface of the lower backing plate 1, and the other end of the calf backing plate 3 is inserted into one of the second limiting ribs 102;
[0041] A first limiting part is detachably connected between the upper surface of the lower backing plate 1 and the back surface of the thigh backing plate 2;
[0042] A second limiting part is detachably connected between the upper surface of the lower backing plate 1 and the back surface of the calf backing plate 3;
[0043] Elastic anti-slip layers 4 are respectively covered on the upper surfaces of the thigh backing plate 2 and the calf backing plate 3.
[0044] During actual use: Place the lower backing plate 1 on the bed so that the thigh backing plate 2 and the calf backing plate 3 are located under the patient's legs;
[0045] When exercising the knee joint, lift the thigh pad 2. The hinge joint between the thigh pad 2 and the calf pad 3 rises. The other end of the calf pad 3 slides on the lower pad 1 under the influence of its own weight, making the thigh pad 2 and the calf pad 3 form a triangular structure. At the same time, insert the other end of the calf pad 3 into one of the limiting ribs two 102 on the lower pad 1, so that the thigh pad 2 and the calf pad 3 are supported in a triangular stable structure. Then place the patient's leg above the thigh pad 2 and the calf pad 3, with the knee joint at the hinge joint between the thigh pad 2 and the calf pad 3. Slowly place the patient's calf on the calf pad, and at the same time, the thigh fits against the thigh pad 2. Affected by the structural state of the thigh pad 2 and the calf pad 3 at this time, the patient's leg is in a flexed state, thereby assisting the patient to recover the flexion movement of the knee joint of the leg. By adjusting the calf pad 3 and the limiting ribs two 102 at different positions, the angle between the calf pad 3 and the thigh pad 2 can be controlled, so as to achieve adjustment and adaptation according to the conditions of different patients.
[0046] When the leg is lifted, the thigh pad 2 is restricted by the first limiting part and can be kept in an inclined state. Then, the calf pad 3 is restricted by the second limiting part and can be kept in a horizontal state. Then place the patient's lower limb on the thigh pad 2 and the calf pad 3, and the patient's leg can be lifted, thereby assisting in reducing swelling of the patient's leg. At the same time, the calf pad 3 and the calf can be surrounded by a strap to limit the movement of the calf.
[0047] Embodiment 2:
[0048] Refer to Figure 1-2 In this embodiment, the difference is that: the thigh pad 2 is composed of a flap 201 and an insertion plate 202. One end of the insertion plate 202 is hinged to one end of the lower pad 1. A slot is opened at the other end of the flap 201. One end of the insertion plate 202 is slidably connected in the slot, and the other end of the insertion plate 202 is hinged to the calf pad 3. A third limiting part is detachably connected between the back of the insertion plate 202 and the slot of the flap 201. The first limiting part is located between the back of the flap 201 and the upper surface of the lower pad 1.
[0049] During actual use: Pull the insertion plate 202 to pull the insertion plate 202 out of the flap 201, thereby increasing the length of the thigh pad 2, and then the problem of different limb lengths of patients can be adapted, the adaptation degree can be improved, and the use effect can be improved. At the same time, the position of the insertion plate 202 can be positioned by the third limiting part, so that the thigh pad 2 maintains this length;
[0050] Elastic anti-slip layers 4 are covered on the fronts of both the flap 201 and the insertion plate 202. The part of the insertion plate 202 located inside the flap 201 is not covered with a protective layer, so that the elastic anti-slip layers 4 on the flap 201 and the insertion plate 202 are at the same height, reducing the problem of discomfort for the patient caused by too large a drop.
[0051] Embodiment 3:
[0052] Referring to Figure 2-5 , the difference of this embodiment is that: an operation opening 203 is formed on the insertion plate 202, and the third limiting part includes: a V-shaped clamping plate 204, a first spring 205, a pushing frame 206 and a second spring 207. The middle of the V-shaped clamping plate 204 is hinged to the back surface of the insertion plate 202. The V-shaped clamping plate 204 is detachably connected to the first spring 205 at the hinge joint with the insertion plate 202. The first spring 205 acts between the V-shaped clamping plate 204 and the insertion plate 202 respectively. There are several card slots on the flap 201. The lower end of the V-shaped clamping plate 204 is clamped with one of the card slots. The lower part of the card slot is a limiting surface, and the upper part of the card slot is an inclined surface. The pushing frame 206 is slidably connected to the back surface of the insertion plate 202. The pushing frame 206 is detachably connected to the second spring 207 between the pushing frame 206 and the back surface of the insertion plate 202. The upper end of the pushing frame 206 can be controlled through the operation opening, and a pushing surface is formed at the lower end of the pushing frame 206.
[0053] During actual use: Pull the insertion plate 202 through the operation opening, so that the insertion plate 202 can be pulled out with one hand. During the pulling process, under the action of the first spring 205, the lower part of the V-shaped clamping plate 204 will be inserted appropriately when passing through each card slot, so as to achieve automatic limiting when pulling out the insertion plate 202. Since the lower part of the card slot is a limiting surface and the upper part of the card slot is an inclined surface, the insertion plate 202 can be restricted from automatically retracting. The inclined surface reduces the scraping and wear between the V-shaped clamping plate 204 and the flap 201. At the same time, through this setting, the problem of excessive sliding under load will not occur;
[0054] When the insertion plate 202 retracts, push the pushing frame through the operation opening 203. The pushing surface of the pushing frame 206 acts between the upper parts of the insertion plate 202 and the V-shaped clamping plate 204, so that the upper part of the V-shaped clamping plate 204 is far away from the back surface of the insertion plate 202, and the lower part of the V-shaped clamping plate 204 is close to the back surface of the insertion plate 202, thereby releasing the limit between the V-shaped clamping plate 204 and the card slot. By continuously pushing, the insertion plate 202 can be reset in the flap 201, and then the hand is far away from the pushing frame 206, and the pushing frame 206 is reset under the influence of the second spring 207;
[0055] Through this setting, it is possible to pull out the insertion plate 202 by pulling the upper part in the operation opening 203, and the insertion plate 202 can be reset by pushing the pushing frame 206, thereby realizing the single-handed operation of retracting and pulling.
[0056] Embodiment 4:
[0057] Referring to Figure 2 , the difference of this embodiment is that: the first limiting part includes: a first clamping plate 5. The upper end of the first clamping plate 5 is hinged to the upper part of the back surface of the flap 201. A plurality of first limiting ribs 101 are equidistantly formed on the upper surface of the lower backing plate 1. The lower end of the first clamping plate 5 is inserted into one of the first limiting ribs.
[0058] During actual use: By inserting the first clamping plate 5 into different limiting ribs 101, the problem of angle adjustment and limitation of the thigh cushion 2 can be realized, and the matching effect with the patient's leg can be improved.
[0059] Embodiment 5:
[0060] Refer to Figure 1-2 In this embodiment, the difference is that: a magic tape 6 is provided between the back surface of the flap 201 and the first clamping plate 5.
[0061] During actual use: Through the magic tape 6, when the first clamping plate 5 is not used, the first clamping plate 5 will not separate from the flap 201, and it is convenient for storage.
[0062] Embodiment 6:
[0063] Refer to Figure 2 In this embodiment, the difference is that: the second limiting part includes: a second clamping plate 7 and a third clamping plate 8. The upper end of the second clamping plate 7 is hinged to the back surface of the calf cushion 3. The lower end of the second clamping plate 7 is inserted into one of the second limiting ribs 102. An opening is formed at the upper end of the second clamping plate 7. One end of the third clamping plate 8 is hinged in the opening. A plurality of third limiting ribs are equidistantly arranged on the back surface of the calf cushion 3. The other end of the third clamping plate 8 is inserted into one of the third limiting ribs.
[0064] During actual use: First, keep the calf cushion 3 horizontal. Then, turn the second clamping plate 7 on the back surface of the calf cushion 3, and insert the second clamping plate 7 into one of the second limiting ribs 102. Then, open the third clamping plate 8 and insert it into one of the third limiting ribs 301 for limitation. At the same time, under the action of the self-weight of the calf cushion 3, with the restriction of the second clamping plate 7 and the third clamping plate 8, the calf cushion 3 will not fall, and the calf cushion 3 is kept in a horizontal state. By replacing the insertion of the second clamping plate 7 with different second limiting ribs 102, the included angle between the calf cushion 3 and the thigh cushion 2 can be adjusted to improve the adaptability to the patient's condition.
[0065] A magic tape is provided between the second clamping plate 7 and the calf cushion 3, which can achieve the same effect as that between the first clamping plate 5 and the flap.
[0066] Embodiment 7:
[0067] Refer to Figure 1 In this embodiment, the difference is that: angle indicators 9 are detachably connected to the hinge joints between the thigh cushion 2 and the lower cushion 1 and between the thigh cushion 2 and the calf cushion 3 respectively.
[0068] During actual use: Through the angle indicator 9, the angle between the thigh cushion 2 and the lower cushion 1 can be visualized, and the angle between the calf cushion 3 and the thigh cushion 2 can be visualized.
