Since these patients do not have the ability to actively raise their lower limbs, they need to use corresponding lower limb raising tools, namely lower limb raising pads.
[0003] Existing lower limb lifting pads, such as "A patient lower limb lifting pad" disclosed in Chinese patent CN221154576U, include a lifting box, the inner wall of the lifting box is slidably connected with an adjusting groove along the up and down directions, a cylinder is fixed to the inner wall of the adjusting groove, a telescopic rod is fixed to the output end of the cylinder, the top of the telescopic rod is fixedly connected to the lifting box, a card plate is clamped on the top of the lifting box, a cushion layer is fixed on the bottom of the card plate, and a rubber pad and a sponge pad are fixed to the inner wall of the cushion layer.
[0004] When in use, the patient's lower limbs are placed on the lifting box, the cross-section of which is C-shaped as a whole, and the cylinder constitutes an active lifting member. The piston rod of the cylinder extends to lift the height of the lifting box to achieve the purpose of raising the height of the lower limbs. The existing lower limb lifting pad has the problem that the lifting pad is only suitable for lifting the patient's lower limbs at a small angle. When the patient's lower limbs need to be lifted at a large angle, the patient's lower limbs will appear at a large angle intersecting the horizontal plane, and the lifting box in the prior art is arranged horizontally as a whole and cannot be adjusted according to the angle of the patient's lower limbs. Therefore, it is not suitable for lifting the patient's lower limbs at a large angle. Utility Model Content

[0019] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0020] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0021] The utility model is a patient lower limb lifting pad. Figures 1 to 3 As shown: it includes a lifting pad base 13, a lower limb support 1 for placing the patient's lower limbs, and a lifting mechanism arranged between the lifting pad base 13 and the lower limb support 1.
[0022] The lower limb support includes a C-shaped support 2 whose axis extends in the front-to-back direction, and a lower limb support base 3 located at the lower side of the C-shaped support. A guide groove 19 extending in the front-to-back direction is provided at the upper end of the lower limb support base, and the lower end of the C-shaped support 2 is guided and moved in the front-to-back direction and assembled in the guide groove 19. The front and rear ends of the C-shaped support are provided with a stop structure 4 for cooperating with the front and rear ends of the lower limb support base to limit the sliding limit of the C-shaped support relative to the lower limb support, that is, the distance between the two stop structures 4 is greater than the length of the lower limb support base 3. In this embodiment, the stop structure is a stop edge structure arranged downward.
[0023] The lifting mechanism includes an active jacking and lifting mechanism and a driven support mechanism 5 arranged in front and back. There are two driven support mechanisms 5, which are arranged in parallel with each other at intervals on the left and right. The two driven support mechanisms and the active jacking and lifting mechanism are distributed at the three vertices of an isosceles triangle, and the connecting line of the two driven support mechanisms is the base of the isosceles triangle.
[0024] The upper end of the active lifting mechanism is hingedly connected to the lower limb support bottom through a hinge structure, and the axis of the hinge structure is arranged along the left and right directions.
[0025] The driven support mechanism includes an upper connecting plate 14 and a lower connecting plate 15. The lower end of the upper connecting plate 14 is hingedly connected to the upper end of the lower connecting plate 15 through an intermediate bolt and nut 17. The upper end of the upper connecting plate 14 is hingedly connected to the bottom of the lower limb support base 3 through an upper bolt and nut 16. The lower end of the lower connecting plate 15 is hingedly connected to the lifting pad base 13 through a lower bolt and nut 18. Each bolt and nut includes a bolt whose axis extends in the left-right direction and a nut matched with the bolt thread. The bolt is connected to the two corresponding connected parts. For example, for the intermediate bolt and nut, the bolt of the intermediate bolt and nut is connected to the upper connecting plate and the lower connecting plate. When the nut of the intermediate bolt and nut is loosened, the bolt constitutes the hinge axis of the upper connecting plate and the lower connecting plate, and the upper connecting plate and the lower connecting plate can rotate relatively. When the nut of the intermediate bolt and nut is tightened, the upper connecting plate and the lower connecting plate are relatively fixed and can no longer rotate. The structural principle of the upper bolts and nuts and the lower bolts and nuts is the same as that of the middle bolts and nuts, and will not be described in detail here. Item 20 in the figure represents the bolt in the upper bolts and nuts, and item 21 represents the nut in the upper bolts and nuts.
[0026] The lifting pad base includes a base top plate 9, a base bottom plate 11 and a base side plate 10 arranged between the base top plate and the base bottom plate, and the base top plate and the base bottom plate are arranged at a distance.
[0027] A vertically arranged guide hole 12 is provided on the top plate and the bottom plate of the base, and the active lifting mechanism includes a vertically arranged lifting screw 7, the lower end of which is used to cooperate with the guide hole for anti-rotation guidance, that is, the lifting screw cannot rotate relative to the lifting pad base. The upper end of the lifting screw is hingedly connected to the bottom of the lower limb support base 3, and a driving screw nut 8 that cooperates with the lifting screw thread is rotatably mounted on the top plate of the base through a bearing, and the driving screw nut cannot move up and down relative to the lifting pad base.
[0028] When in use, when the patient's lower limbs need to be raised, the patient's lower limbs are placed on the C-shaped support of the lower limb support, the nuts of the bolts and nuts are loosened, the drive nut is screwed, the lifting screw moves upward to lift the height of the lower limb support, and the height of the patient's lower limb is gradually raised. During the lifting process, the lower limb support rotates adaptively around the axis of the hinge hole at the upper end of the lifting screw to adapt to the angle of the patient's lower limb. At the same time, the upper connecting rod and the lower connecting rod of the two driven support mechanisms also swing adaptively to adapt to the height of the lower limb support. After the lower limb support is lifted to the right height, the nuts of the bolts and nuts are tightened. At this time, the driven support mechanism forms a rigid support that cannot rotate, and the two driven support mechanisms and an active lifting mechanism form a stable triangular support for the lower limb support. In the process of the lower support moving upward with the lifting screw, the patient's lower limb with the C-shaped support will also slide in the front and rear directions relative to the lower limb support base to avoid hard friction between the patient's lower limb and the lower limb support, which will cause damage to the patient's lower limb.
[0029] In other embodiments of the utility model, there may be only one driven support mechanism; the active lifting mechanism may also be a lifting mechanism such as an electric push rod, a pneumatic cylinder or a hydraulic cylinder that can actively lift the lower limb support.
