Description

Technical Field

[0001] This application relates to the field of medical supplies technology, specifically to an angle-adjustable lower limb elevation pad. Background Art

[0002] Lower limb elevation pads are mainly used to elevate the patient's lower limbs after venous surgery or lower limb fracture reduction to promote venous blood return to the heart and reduce lower limb swelling. Currently, most clinically available elevation pads are made of sponge material, making it impossible to control the elevation height as needed. Chinese patent application number 202320157315.1, entitled "A Lower Limb Elevation Pad Device After Lower Limb Varicose Vein Surgery," discloses a method where a drive motor is controlled by a lifting button to rotate forward and backward. The drive motor rotates the drive shaft, which in turn rotates the drive screw vertically. The screw then drives a nut to raise and lower the lifting platform horizontally, thus achieving the function of raising and lowering the lower limb elevation pad. However, during use, it was found that when the lower limb elevation pad is at a high height, the lower leg is continuously raised while the thigh remains suspended, failing to receive effective support and affecting the patient's lying comfort. Therefore, it is necessary to improve the existing lower limb elevation pads. Utility Model Content

[0003] In view of the above problems, this application provides an angle-adjustable lower limb elevation pad to solve the technical problem that the lower limb elevation pad in the above technology cannot provide adhesive support for the thigh.

[0004] To achieve the above objectives, this application provides an angle-adjustable lower limb elevation pad, comprising:

[0005] Base;

[0006] A pad, set on the base for elevating the lower limbs, includes a calf support pad and a thigh support pad;

[0007] A support frame for supporting the pad body includes a first support plate for supporting the calf support pad and a second support plate for supporting the thigh support pad;

[0008] A multi-link hinge assembly for connecting a first support plate and a second support plate includes a first link, a second link, a third link, and a fourth link; the first end of the first link is hinged to the first support plate, the second end of the first link is hinged to the first end of the second link, and the second end of the second link is hinged to the second support plate; the first end of the third link is hinged to the first support plate, the second end of the third link is hinged to the first end of the fourth link, the second end of the fourth link is hinged to the second support plate, and the middle portions of the second link and the middle portions of the third link are hinged to each other;

[0009] The drive assembly, including a drive motor, is connected to the multi-link hinge assembly and is used to drive the multi-link hinge assembly to extend or retract, so that the second support plate swings out or retracts relative to the first support plate.

[0010] Furthermore, the multi-link hinge assembly includes two sets of first link, second link, third link, and fourth link arranged parallel to each other along the width direction of the first support plate and the second support plate.

[0011] Furthermore, the drive assembly also includes a drive rod and a connecting rod;

[0012] The first drive rod is connected to the drive motor and is driven by the drive motor to move axially;

[0013] The two ends of the connecting rod are respectively connected to the two third connecting rods; the middle part of the connecting rod is provided with a swing arm, and the swing arm is hinged to the driving rod.

[0014] Furthermore, the calf support pad and the thigh support pad are made of silicone and are covered with a pillowcase made of fabric.

[0015] Furthermore, when the second support plate retracts relative to the first support plate, the angle between the second support plate and the horizontal plane is 80-90 degrees; when the second support plate swings outward to its maximum extent, the angle between the second support plate and the horizontal plane is 30-40 degrees.

[0016] Furthermore, the side of the base is provided with buttons for controlling the drive motor to rotate forward or backward.

[0017] Furthermore, the edges of the first, second, and third sides of the base are respectively provided with upwardly protruding protective plates, the fourth side of the base is open, and the second support plate is located above the fourth side.

[0018] Furthermore, both the first support plate and the second support plate are made of plastic.

[0019] Unlike existing technologies, the above-mentioned adjustable lower limb elevation pad includes a support frame and a multi-link hinge assembly. The support frame includes a first support plate for supporting the calf support pad and a second support plate for supporting the thigh support pad. The multi-link hinge assembly connects the first support plate and the second support plate, allowing the second support plate to swing and extend or retract relative to the first support plate. This allows for flexible adjustment of the angle of the second support plate and the thigh support pad on it according to actual needs, providing effective support for the thigh and improving the comfort of the patient when lying down with their lower limbs elevated.

For those skilled in the art to which this application pertains, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0043] In related technologies, the shape of lower limb elevation pads is fixed, thus failing to effectively support both the calf and thigh simultaneously. Especially when the pad is high, the thigh remains suspended and unsupported, affecting patient comfort. To address this issue, the following embodiments provide an angle-adjustable lower limb elevation pad to improve patient comfort when elevating their lower limbs.

[0044] See also Figures 1 to 5 This embodiment discloses an angle-adjustable lower limb elevation pad. The angle is adjustable because the angle of the thigh support pad 22 can be increased or decreased to accommodate patients of different heights or different lying positions, ensuring effective support for the thighs at all times.

[0045] like Figure 1As shown, the adjustable lower limb elevation pad of this embodiment includes: a base 1, a pad body 2, a support frame 3, a multi-link hinge assembly 5, and a drive assembly 4.

[0046] The base 1 is located at the very bottom of the adjustable lower limb elevation pad. The base 1 is used to set up and support the pad body 2, support frame 3, multi-link hinge assembly 5, and drive assembly 4. The base 1 can be made of materials with a certain structural strength, such as plastic.

[0047] The pad 2 is mounted on the base 1 to elevate the lower limbs. The pad 2 includes a calf support pad 21 and a thigh support pad 22. Figure 1 and Figure 2 As shown, during use, the calf support pad 21 is located away from the patient, while the thigh support pad 22 is closer to the patient than the calf support pad 21. The calf support pad 21 and the thigh support pad 22 can be a single, integrated pad, meaning they are essentially different parts of the same pad. Alternatively, they can be two separate pads. Both the calf support pad 21 and the thigh support pad 22 are made of silicone and covered with a fabric pillowcase. They can also be made with fluffy fillings such as cotton or sponge. This application does not limit the specific structure of the calf support pad 21 and the thigh support pad 22.

[0048] The support frame 3 supports the pad 2 and includes a first support plate 31 for supporting the calf support pad 21 and a second support plate 32 for supporting the thigh support pad 22. The first support plate 31 and the second support plate 32 are two independent plates with a certain supporting force. Specifically, the first support plate 31 and the second support plate 32 can be made of plastic, fiberglass board, carbon fiber board, stainless steel plate, etc.

[0049] like Figure 3 and Figure 4 As shown, the multi-link hinge assembly 5 is used to connect the first support plate 31 and the second support plate 32, and includes a first link 51, a second link 52, a third link 53, and a fourth link 54; the first end of the first link 51 is hinged to the first support plate 31, the second end of the first link 51 is hinged to the first end of the second link 52, and the second end of the second link 52 is hinged to the second support plate 32; the first end of the third link 53 is hinged to the first support plate 31, the second end of the third link 53 is hinged to the first end of the fourth link 54, the second end of the fourth link 54 is hinged to the second support plate 32, and the middle part of the second link 52 is hinged to the middle part of the third link 53.

[0050] The drive assembly 4 includes a drive motor 43, which is connected to the multi-link hinge assembly 5 and is used to drive the multi-link hinge assembly 5 to extend or retract, so that the second support plate 32 swings out or retracts relative to the first support plate 31.

[0051] like Figure 4 As shown, the multi-link hinge assembly 5 includes two sets of first links 51, second links 52, third links 53, and fourth links 54 arranged parallel to each other along the width direction of the first support plate 31 and the second support plate 32. Specifically, the two first links 51 are arranged opposite each other along the width direction of the first support plate 31 and the second support plate 32 (i.e.,...). Figure 1 The direction indicated by the middle arrow X (and the direction indicated by the arrow Y in the length direction) is on both sides. Similarly, the second link 52 to the fourth link 54 are also arranged opposite to each other on both sides of the width direction of the first support plate 31 and the second support plate 32.

[0052] like Figure 4 and Figure 5 As shown, the drive assembly 4 further includes a drive rod 41 and a connecting rod 42; the drive rod 41 is connected to the drive motor 43 and is driven by the drive motor 43 to move axially; the two ends of the connecting rod 42 are respectively connected to two third connecting rods 53; a swing arm is provided in the middle of the connecting rod 42, and is hinged to the drive rod 41 through the swing arm. The drive motor 43 and the drive rod 41 can be connected by a gear and a rack (the gear is set on the drive shaft, the rack is fixed on the drive rod 41, and the gear and rack mesh), and the drive motor 43 drives the drive rod 41 to move axially by rotating forward and reverse, and then the drive rod 41 drives the connecting rod 42 to rotate and swing, thereby the entire multi-link hinge assembly 5 swings outward to extend and retract. Figure 2 and Figure 3 As shown, Figure 3 This is a schematic diagram of the multi-link hinge assembly 5 in its retracted state (i.e., state two). In this state, the second support plate 32 and the thigh support pad 22 retract inwards, thereby increasing the angle with the horizontal direction. Figure 1 and Figure 4 As shown, Figure 4 This is a schematic diagram of the multi-link hinge assembly 5 in the outward swing-out extension state (i.e., state one). At this time, the second support plate 32 and the thigh support pad 22 swing outward and extend, with a small angle between them and the horizontal direction. Therefore, by controlling the extension amount of the multi-link hinge assembly 5, the angle between the second support plate 32 and the thigh support pad 22 and the horizontal direction can be adjusted, thus making the angle of the thigh support pad 22 adjustable.

[0053] In one embodiment, when the second support plate 32 retracts relative to the first support plate 31, the angle between the second support plate 32 and the horizontal plane is 80-90 degrees; when the second support plate 32 swings outward to its maximum extent, the angle between the second support plate 32 and the horizontal plane is 30-40 degrees.

[0054] like Figure 1 As shown, in order to facilitate the control of the angle of the thigh support pad 22, in one embodiment, a button 11 is provided on the side of the base 1 for controlling the drive motor 43 to rotate forward or backward.

[0055] like Figure 1 and Figure 2 As shown, the first, second, and third edges of the base 1 are respectively provided with upwardly protruding protective plates 12, and the fourth side of the base 1 is open, with the second support plate 32 located above the fourth side. The protective plates 12 on the first, second, and third sides form a relatively closed installation space, making the pad 2 and support frame 3 installed on it more securely. The first support plate 31 can be fixed to the base 1 by bolts or other fasteners. In some embodiments, to achieve height adjustment of the calf support pad 21, the first support plate 31 can use the height-lifting structure disclosed in application number 202320157315.1, entitled "A Lower Limb Elevation Pad Device After Lower Limb Varicose Vein Surgery," to adjust the height of the first support plate 31 relative to the base.

[0056] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
