Technical Field
[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a multifunctional human lower limb placement auxiliary device. Background Art
[0002] The multifunctional lower limb placement assist device is a device used in the field of medical rehabilitation. It is mainly used to help patients perform rehabilitation training for their lower limbs, so that patients can get proper support and exercise when using it, thereby promoting the recovery of lower limb function. In addition, the device may also have other functions, such as disinfection, medication, sterile isolation, etc., to meet the rehabilitation needs of different patients.
[0003] Currently, lower limb positioning assist devices in medical practice primarily utilize a combination of plaster and bandages. Specifically, the patient's lower limbs are first secured with plaster, then suspended above the bed using straps to provide both positional support and support. While this traditional device is simple and inexpensive, it can meet basic positioning and restraint requirements to a certain extent. However, due to its structural limitations, patients often cannot adjust the relative position of their legs to their comfort level. Maintaining the same position for extended periods can lead to poor local blood circulation and increase the risk of pressure sores. To address this, we have developed a multifunctional lower limb positioning assist device. Utility Model Content
[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a multifunctional human lower limb placement auxiliary device.

[0007] As mentioned above, the inner bottom end of the limiting frame is fixedly connected with an inner lifting airbag, and the inner lifting airbag is located at the center of the bottom surface of the outer covering airbag, and the inner lifting airbag is covered between the outer covering airbag and the bottom end of the inner wall of the limiting frame.
[0008] As mentioned above, the lower end of the inner part of the limit frame is rotatably connected with a rotating shaft, and the lower end of the outer wall of the rotating shaft is also located at the inner center of the limit slide, the top end of the outer wall of the rotating shaft is connected through the center of the bottom surface of the limit frame, and the top of the outer wall of the rotating shaft is rotatably connected to the inner part of the limit frame.
[0009] As mentioned above, the outer wall of the bottom end of the rotating shaft passes through the center of the top surface of the limiting slide, and the bottom of the outer wall of the rotating shaft is rotatably connected to the inner center of the limiting slide.

[0011] Compared with the existing technology, this multifunctional lower limb placement auxiliary device has the following beneficial effects:
[0012] 1. After the patient places his lower limbs into the arc groove in the center of the limiting frame, the utility model activates the outer covering airbag to initially limit the patient's lower limbs. Then, by activating the inner lifting airbag, the patient's lower limbs can be lifted to 20 to 30 cm above the heart plane.

Therefore, while providing the patient with a comfortable lower limb lifting function, the patient's lower limb circumference can also be measured.
[0013] 2. The utility model provides limiting guide rails on both sides of the inner part of the limiting base plate, so that the patient can move the lower limbs horizontally along the outer wall of the limiting guide rails through the limiting frame and the limiting slide plate according to the patient's own comfort level, thereby changing the relative position between the patient and the lower limbs. At the same time, since a rotating shaft is provided between the limiting slide plate and the limiting frame, the limiting frame can be rotated according to actual conditions under the action of the rotating shaft while moving through the limiting guide rails.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a multifunctional human lower limb placement auxiliary device, including a limit frame 1, an outer layer covering air bag 2 is fixedly connected to the inner center of the limit frame 1, and a plurality of circumference measuring instruments 101 are fixedly connected to both sides of the inner part of the limit frame 1 at the same time, the bottom center of the limit frame 1 is rotatably connected to the limit slide 3, and the bottom surface of the limit slide 3 is slidably connected to the limit base plate 301, the limit slide 3 is located at one end inside the limit base plate 301, and the limit slide 3 is slidably connected to the inner end of the limit base plate 301, the limit frame 1 is located at the top end of the limit base plate 301, and the limit frame 1 is slidably connected to the top end of the limit base plate 301 through the limit slide 3.
[0022] After the patient places his lower limbs into the arc groove in the center of the limiting frame 1, the outer covering airbag 2 is activated to initially limit the patient's lower limbs. Then, the inner lifting airbag 202 can be activated to lift the patient's lower limbs to 20 to 30 cm above the heart plane. The inner clamping airbag 201 can be activated to clamp the patient's lower limbs for a second time. By arranging limiting guide rails 303 on both sides of the limiting bottom plate 301, the patient can move his lower limbs horizontally along the outer wall of the limiting guide rail 303 through the limiting frame 1 and the limiting slide plate 3 according to his own comfort level. Change the relative position between the patient and the lower limbs. At the same time, since a rotating shaft 302 is provided between the limiting slide 3 and the limiting frame 1, the limiting frame 1 can be rotated according to actual conditions under the action of the rotating shaft 302 while moving through the limiting guide rail 303. Therefore, the patient can change the relative position between himself and the lower limbs according to his own comfort level. This not only improves the patient's comfort level, but also allows the patient to adjust the position of the leg according to actual needs to adapt to different rehabilitation needs or relieve the discomfort caused by long-term fixation.
[0023] like Figure 1-3 As shown, both sides of the outer wall of the outer layer covering airbag 2 are fixedly connected with the inner layer clamping airbag 201, and the inner layer clamping airbag 201 is located on both sides of the inside of the limiting frame 1, and the outer wall of one side of the inner layer clamping airbag 201 is fixedly connected to one side of the inside of the limiting frame 1, and the inner layer clamping airbag 201 is located between the limiting frame 1 and the inner layer clamping airbag 201 interlayer. The inner layer clamping airbag 201 is set on both sides of the outer wall of the outer layer covering airbag 2. After the outer layer covering airbag 2 is used to perform preliminary fixation and limitation of the patient's lower limbs, further stable positioning of the patient's lower limbs can be achieved by inflating the inner layer clamping airbag 201, ensuring that the patient's lower limbs are reliably limited inside the limiting frame 1, so as to provide safer and more effective support and fixation.
[0024] The inner bottom end of the limiting frame 1 is fixedly connected to an inner lifting airbag 202, and the inner lifting airbag 202 is located at the center of the bottom surface of the outer covering airbag 2. The inner lifting airbag 202 is covered between the outer covering airbag 2 and the lower end of the inner wall of the limiting frame 1. The inner lifting airbag 202 is set at the lower end of the outer wall of the outer covering airbag 2. Before the inner clamping airbag 201 fixes the patient's lower limbs, it can inflate itself to lift the patient's lower limbs so that the lower limbs are 20 to 30 cm higher than the heart plane, and then the patient's lower limbs are re-positioned by the inner clamping airbag 201.
[0025] like Figure 1 、 Figure 2 and Figure 4As shown, the lower end of the limit frame 1 is rotatably connected to a rotating shaft 302, and the lower end of the outer wall of the rotating shaft 302 is also located at the inner center of the limit slide 3. The rotating shaft 302 is set at the bottom end of the limit frame 1 and the inner center of the limit slide 3, which can facilitate the subsequent rotational connection of the limit frame 1 with the top center of the limit slide 3 through the rotating shaft 302.
[0026] The top of the outer wall of the rotating shaft 302 is connected to the center of the bottom surface of the limit frame 1, and the top of the outer wall of the rotating shaft 302 is connected to the inside of the limit frame 1 for rotation. By passing the top of the outer wall of the rotating shaft 302 through the center of the bottom surface of the limit frame 1, the internal center of the limit frame 1 and the top of the outer wall of the rotating shaft 302 can rotate relative to each other.
[0027] The outer wall of the bottom end of the rotating shaft 302 passes through the center of the top surface of the limiting slide 3, and the bottom of the outer wall of the rotating shaft 302 is rotatably connected to the internal center of the limiting slide 3. After the outer wall of the bottom end of the rotating shaft 302 passes through the center of the top surface of the limiting slide 3, the limiting frame 1 can be rotated through the rotating shaft 302 and the top center of the limiting slide 3.
[0028] Multiple limiting guide rails 303 are fixedly connected on both sides of the limiting base plate 301, and one end of the outer wall of the limiting guide rail 303 is located on the inner side of the limiting slide 3, the outer wall of one end of the limiting guide rail 303 passes through the outer wall of the limiting slide 3, and the inner side of the limiting slide 3 is slidably connected to one end of the outer wall of the limiting guide rail 303. By arranging the limiting guide rails 303 on both sides of the limiting base plate 301 and passing the outer wall of one end of the limiting guide rail 303 through the inner side of the limiting slide 3, the moving trajectory of the limiting slide 3 can be limited, and the limiting slide 3 can be moved horizontally along the outer wall of the limiting guide rail 303.
[0029] Working principle: The inner layer clamping airbag 201 is set on both sides of the outer wall of the outer layer covering airbag 2. After the outer layer covering airbag 2 is used to initially fix and limit the patient's lower limbs, the inner layer clamping airbag 201 is inflated to achieve further stable positioning of the patient's lower limbs, ensuring that the patient's lower limbs are reliably restricted inside the limiting frame 1 to provide safer and more effective support and fixation. The inner layer lifting airbag 202 is set at the bottom end of the outer wall of the outer layer covering airbag 2. Before the inner layer clamping airbag 201 is used to fix the patient's lower limbs, it can be inflated to raise the patient's lower limbs to 20 to 30 cm above the heart plane. After the patient's lower limbs are secondary positioned by the inner layer clamping airbag 201, the rotating shaft 302 is rotated. By being arranged at the bottom end of the limit frame 1 and the inner center of the limit slide 3, it is convenient for the subsequent limit frame 1 to be rotatably connected with the top center of the limit slide 3 through the rotating shaft 302. By passing the top of the outer wall of the rotating shaft 302 through the bottom center of the limit frame 1, the inner center of the limit frame 1 and the top of the outer wall of the rotating shaft 302 can be rotated relative to each other. After the outer wall of the bottom end of the rotating shaft 302 passes through the top center of the limit slide 3, the limit frame 1 can be rotated with the top center of the limit slide 3 through the rotating shaft 302. By arranging the limiting guide rails 303 on both sides of the inner part of the limiting bottom plate 301 and passing the outer wall of one end of the limiting guide rail 303 through one side of the inner part of the limiting slide 3, the moving trajectory of the limiting slide 3 can be limited, and the limiting slide 3 can be moved horizontally along the outer wall of the limiting guide rail 303.
