[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.

[0033] In the description of the present invention, it should be understood that the terms "left side", "right side", "upper part", "lower part", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second", etc. do not indicate the importance of the components, and therefore cannot be understood as a limitation on the present invention. The specific dimensions used in this embodiment are only for illustrating the technical solution, and do not limit the scope of protection of the present invention.

[0034] like Figure 1 and Figure 2 The embodiment of the present application discloses an adjustable leg support for checking the degree of leg swelling, including a core shaft 1, a rocker arm 11, a positioning rod 12, a positioning plate 13 and a support plate 14. Two core shafts 1 are provided and are respectively fixed on both sides of a nursing bed 8 along its own length direction. The two core shafts 1 are both sleeved with a coaxially distributed sleeve 10, and the sleeve 10 is rotatably connected to the core shaft 1.

[0035] There are two swing rods 11, which are respectively vertically connected to the two sleeves 10, and there are two positioning rods 12, which are respectively connected to the two sleeves 10 and form an angle with the swing rods 11, and the degree of the angle is greater than 90 degrees. The positioning rods 12 are made of acrylic plate.

[0036] like Figure 1 and Figure 2 The positioning plate 13 is vertically connected to the nursing bed 8 and is arranged opposite to the positioning rod 12. The positioning plate 13 is provided with a plurality of positioning holes 131 which are equidistantly distributed around the axis of the core shaft 1. The positioning rod 12 is provided with a telescopic portion 2 for inserting into the positioning holes 131. The positioning rod 12 fits with the positioning plate 13, and the operator can identify the position of the positioning hole 131 through the positioning rod 12.

[0037] like Figure 3 The telescopic part 2 includes an insertion rod 21 and a spring 22. The insertion rod 21 slides through the positioning rod 12 in a direction parallel to the axis of the core shaft 1. One end of the insertion rod 21 is inserted into the positioning hole 131, and the other end is provided with a pad 23. The diameter of the pad 23 is larger than the diameter of the insertion rod 21. The spring 22 is sleeved on the insertion rod 21, and the two ends of the spring 22 are respectively connected to the pad 23 and the positioning rod 12; when the insertion rod 21 is plugged into the positioning hole 131, the spring 22 is in a natural state.

[0038] like Figure 1 The support plate 14 is connected between the two swing rods 11 by means of the damping shaft 4. The damping shaft 4 generates friction force by means of mutual compression between the gaskets, thereby providing a damping effect. When there is relative motion or inertial motion between the swing rod 11 and the support plate 14, the damping shaft 4 starts to rotate. During the rotation process, the damping material (such as the gasket) is stirred to generate internal damping force, so that the support plate 14 stops at any angle to meet the patient's leg position requirements.

[0039] The insertion of the rod 21 and the positioning hole 131 limits the rotation of the positioning rod 12 and fixes the swing rod 11; in the initial position, the swing rod 11 is located on the side of the nursing bed 8 and is parallel to the length direction of the nursing bed 8. The support plate 14 is vertically distributed and vertically passes through the nursing bed 8 downward. A slot for the support plate 14 to pass through is reserved on the nursing bed 8 to save the space required for the leg support. When in use, the operator pulls the pad 23 outward to separate the rod 21 from the positioning hole 131. At this time, the spring 22 is compressed and elastically deformed. The operator rotates the swing rod 11 upward to a certain angle, such as 15°, 30°, 45° or 60°. After determining the angle, the pad 23 is released, so that the rod 21 is inserted into the corresponding positioning hole 131 under the elastic tension of the spring 22, and the swing rod 11 is fixed. Subsequently, the operator rotates the support plate 14 so that the angle position of the support plate 14 is consistent with the direction of the patient's legs, thereby improving the comfort of the support.

[0040] like Figure 3 and Figure 4 The core shaft 1 is inserted into the nursing bed 8, the bottom surface of the nursing bed 8 is threadedly connected with the limit screw 3, and the core shaft 1 is provided with a limit hole 31 for inserting the limit screw 3. The limit screw 3 and the limit hole 31 are plugged to fix the core shaft 1 and the nursing bed 8.

[0041] Two mutually parallel angle plates 32 are provided on the positioning plate 13, and the two angle plates 32 are fixed to the bottom surface of the nursing bed 8 by screws. The core shaft 1 and the positioning plate 13 are fixed to the nursing bed 8 by a detachable connection structure, and the leg support structure can be selected according to actual use needs, which is convenient and flexible, and also convenient for the replacement of components.

[0042] like Figure 5 and Figure 6 The support plate 14 is provided with a placement groove 5 for placing the electric blanket, and the groove wall of the placement groove 5 is provided with a wire groove 6 extending to the outside of the support plate 14, and the placement groove 5 is covered with a soft pad 61, and the soft pad 61 is made of heat-resistant material, and a plurality of air holes 611 are formed through the soft pad 61, and a plurality of laces 62 distributed along the periphery thereof are provided on the soft pad 61, and the laces 62 are connected to the support plate 14 through a Velcro 63. The Velcro 63 includes a first surface and a second surface, the first surface is a soft fiber, and the second surface is an elastic fiber with hooks and barbs, and the first surface and the second surface are hooked and fixed.

[0043] In low temperature or other medical needs, the operator removes the soft pad 61, puts the electric blanket into the placement slot 5, passes the electric blanket wires through the wire slot 6, and then re-lays the soft pad 61 in the placement slot 5 and fixes it with Velcro 63, and covers the electric blanket with the soft pad 61. The patient puts his legs on the soft pad 61, and the electric blanket is powered on to heat the patient's legs, so as to promote heat preservation and blood circulation.

[0044] like Figure 1 and Figure 5 The side wall of the support plate 14 is provided with a through slot 7 for placing a measuring ruler 72. The side of the support plate 14 for supporting the leg is provided with an outlet 71 connected to the through slot 7. The outlet 71 is used for the measuring ruler 72 to pass through. The measuring ruler 72 is preferably a soft ruler. The medical staff can place the soft ruler in the through slot 7 and pass the starting end of the soft ruler through the outlet 71. The soft ruler is used to surround the patient's leg for measurement to provide data support for treatment. At the same time, the provision of the through slot 7 reduces the occupation of the external space by the soft ruler, which is convenient for storage and management.

[0045] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
