Description

Technical Field

[0001] The utility model relates to the medical field, in particular to a neutral position foot pad for lying flat or lying sideways. Background Art

[0002] Foot drop is one of the signs of orthopedics. It is a common complication in patients with coma, paraplegia, hemiplegia caused by stroke, peroneal nerve injury, Achilles tendon contracture, etc. It is also the main cause of abnormal gait in patients. The ankle joint is the movement joint of the human body, and it is also the joint closest to the ground and bears the most weight. The neutral position of the ankle joint is 90° (relative to the calf bone). When foot drop occurs, the ankle joint is contracted and cannot be in the neutral position. When the patient sits, the two lower limbs hang naturally.

[0003] Foot drop will not only cause the patient's ankle joint to be in a non-functional position for a long time, ankle stiffness, difficulty walking, etc., but will also affect the patient's lower limb motor function. Therefore, it is necessary to intervene as early as possible in the patient's rehabilitation stage to prevent and treat foot drop.

[0004] However, the traditional device for preventing foot drop is a fixed structure that integrates the legs and feet, which is inconvenient to remove and put on. When the patient is in a side-lying position, the support member on the leg, which is relatively hard on the skin, is easy to press on the skin of the other calf, causing mechanical compression or discomfort. In addition, when the patient is in a side-lying position, the outer ankle bone is in long-term contact and pressure with the fixed structure or the bed surface, which is prone to pressure sores.

[0005] Therefore, a neutral foot pad is needed that can be conveniently used in both supine and side-lying positions. Utility Model Content

[0006] The utility model aims to provide a neutral foot pad for both lying flat and lying sideways. Through the assembly and disassembly of the side pad, the flexible adjustment of the foot pad and the pressure relief effect of the side pad, the foot pad can be suitable for lying flat or lying sideways in bed.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A neutral position foot pad for both lying flat and side lying comprises a main pad body, a side pad and two foot pads, wherein the two foot pads can be symmetrically attached to one side surface of the main pad body respectively, and a fixing belt is provided on the side of the foot pad away from the main pad body, the side pad is connected to the side wall of the main pad body through a fixing assembly, when the side pad is located on one side in the length direction of one of the foot pads through the fixing assembly, the main pad body is in a side lying position use state, and when the side pad is removed from the main pad body, the main pad body is in a flat lying position use state.

[0009] Compared with the prior art, the neutral position foot pad for lying flat or sideways using the above technical solution has the following beneficial effects:

[0010] 1. The neutral position foot pad for lying flat or side lying of the utility model is used. The foot pad is attached to the main pad body and fixed by winding a fixing belt to achieve the connection between the ankle, foot, foot pad and main pad body, supporting the foot so that the ankle joint is in a neutral position. While it is easy to wear and remove, it achieves the purpose of preventing foot drop. Due to the integrity of the main pad body, the main pad body can be placed at the foot board of the bed and the position of the patient's pillow can be appropriately adjusted to effectively increase the support effect for both feet. That is, in the lying flat state, according to the use requirements or the current condition of the foot, it can be decided whether to adjust the position of the main pad body or decide whether to connect the foot pad and the main pad body to increase the support effect or adapt to the current foot condition. In addition, the side pad can be arranged on the side of the main pad body corresponding to the heel to achieve the prevention and treatment effect of heel pressure sores in the lying flat state.

[0011] Second, by docking the side pads with the main pad body and adjusting the attachment position of the foot pad, the purpose of supporting the feet in the side-lying state can be achieved; since the fixed structure does not require a harder support member to be applied to the legs, the mechanical compression of the leg skin when lying on the side can be effectively avoided; and the pressure-reducing and buffering effect of the side pads can relieve the compression of the outer ankle bone when it contacts the bed surface, and in this state, foot drop and pressure sores can be prevented at the same time.

[0012] 3. At the same time, since the side pads and the main pad body are relatively independent, they can be flexibly adjusted according to usage requirements. The foot pad is easy to wear and effectively improves the work efficiency of medical staff. It is easy to use and convenient for patients or their families to adjust independently.

[0013] Preferably, the side of the foot pad facing the main pad body is provided with a hook surface of Velcro, and the side of the main pad body facing the foot pad is provided with a fur surface of Velcro, and the fur surface completely covers the surface. By utilizing the characteristics of Velcro, the foot pad can be quickly and repeatedly removed or reattached; and with sufficient fur surface coverage, the foot pad attachment position can be adaptively adjusted according to the thickness of the patient's legs.

[0014] Preferably, one end of the fixing belt is fixedly connected to the side wall of the foot pad, and the foot pad is provided with a flat through-hole, and the end of the fixing belt away from the foot pad can pass through the through-hole and adhere to the surface of the fixing belt. After the fixing belt is wrapped around the foot and attached and fixed, since part of the fixing belt passes through the through-hole and is located in the foot pad, when supporting the foot, part of the force will be pressed on the fixing belt in the foot pad, which can effectively avoid the problem of the foot directly slipping off when the attachment structure is accidentally released.

[0015] Preferably, the foot pad is made of transparent material, or the position of the foot pad corresponding to the perforation is made of transparent material. The light-transmitting property of the transparent material allows medical staff to directly observe the condition of the fixing belt at the perforation, thereby facilitating the end of the fixing belt not connected to the foot pad to pass through the perforation.

[0016] Preferably, the fixing assembly includes a limit plate, a limit block, an elastic member and a button. The limit plates and the limit blocks are each provided with two, and the two limit blocks are movably connected to the side pads through the limit plates, respectively. The elastic member is provided between the two limit plates. The side wall of the main pad body is provided with a limit groove for the limit plate and the elastic member to be placed. The button is movably provided on the side wall of the side pad, and the button is fixedly connected to the limit plate. By utilizing the telescopic characteristics of the elastic member, the two limit plates and the limit blocks can be smoothly controlled to approach or move away from each other. In the approaching state, they can be smoothly inserted into the limit groove to achieve docking, and in the distant state, they can be separated from each other in the limit groove to achieve the purpose of locking. Moreover, by directly controlling the button, the position of the limit plate can be regulated after the side pad and the main pad body are docked, and then the elastic member can be pressed to achieve the purpose of disassembling the side pad and the main pad body.

[0017] Preferably, a slope or an arc surface is provided on the side of the limit block away from the limit plate. By utilizing the guiding effect of the slope or the arc surface, part of the force is pressed on the limit block and the elastic member while pushing the side pad, so that the limit block, the limit plate and the elastic member directly enter the limit groove, that is, the side pad and the main pad body are directly and quickly connected, which is convenient for quick operation without external tools or manual pressure on the elastic member, and the operation is convenient and efficient.

[0018] Preferably, the end of the button away from the limiting plate does not extend beyond the side wall of the side pad. In a normal state or when pressed, the button is hidden in the side pad, which can effectively avoid discomfort caused by the button protruding from the side pad and avoid the problem of accidental pushing of the limiting plate causing the side pad and the main pad body to separate.

[0019] Preferably, a support pad is also included, and the support pad can be attached to the surface of the main pad body and is located between the two foot pads. The support pad can provide support and limit between the two feet by using its blocking function to prevent the foot pads from losing their neutral support effect when they are accidentally detached, and the support pad can relieve the pressure on the medial malleolus of the lower foot and the medial malleolus of the upper foot.

[0027] The utility model is further described below in conjunction with the accompanying drawings.

[0028] like Figures 1 to 6 The neutral position foot pad for both lying flat and side lying shown comprises a main pad body 1 , a side pad 2 and two foot pads 3 .

[0029] The two foot pads 3 can be symmetrically attached to one side surface of the main pad body 1 , and a fixing belt 4 is provided on the side of the foot pad 3 away from the main pad body 1 .

[0030] Regarding the attachment structure of the foot pad 3 and the main pad body 1, in order to facilitate adjustment and subsequent reuse, the foot pad 3 is provided with a hook surface of Velcro on the side facing the main pad body 1, and the main pad body 1 is provided with a fleece surface 10 of Velcro on the side facing the foot pad 3.

[0031] In order to flexibly adjust the attachment position of the foot pad 3, the fleece surface 10 on the main pad body 1 completely covers the surface.

[0032] Regarding the connection structure between the fixing strap 4 and the foot pad 3, specifically, one end of the fixing strap 4 is fixedly connected to the side wall of the foot pad 3, and the foot pad 3 is provided with a flat through hole 30, and the end of the fixing strap 4 away from the foot pad 3 can pass through the through hole 30 and adhere to the surface of the fixing strap 4. In this embodiment, the surface of the movable end of the fixing strap 4 is provided with a Velcro fur surface 10, and the surface of the fixing strap 4 is provided with a Velcro hook surface.

[0033] In order to facilitate medical staff to operate and connect and save time for wearing, the foot pad 3 is made of transparent material, or the position of the foot pad 3 corresponding to the perforation 30 is transparent material. In this embodiment, the foot pad 3 is made of transparent silicone with a certain toughness, and the inner wall of the perforation 30 is provided with a film with low friction resistance.

[0034] The side pad 2 is connected to the side wall of the main pad body 1 through the fixing component 5. When the side pad 2 is located on one side in the length direction of one of the foot pads 3 through the fixing component 5, the main pad body 1 is in a side-lying position. When the side pad 2 is removed from the main pad body 1, the main pad body 1 is in a supine position.

[0035] The fixing assembly 5 includes a limit plate 50, a limit block 51, an elastic member 52 and a button 53. There are two limit plates 50 and two limit blocks 51. The two limit blocks 51 are movably connected to the side pads 2 through the limit plates 50 respectively. The elastic member 52 (elastic silicone, elastic rubber or reset spring) is arranged between the two limit plates 50. The side wall of the main pad body 1 is provided with a limit groove 11 for the limit plate 50 and the elastic member 52 to be placed. The button 53 is movably arranged on the side wall of the side pad 2, and the button 53 and the limit plate 50 are fixedly connected.

[0036] In order to facilitate the rapid connection between the side wall and the main cushion body 1 , a slope or an arc surface is provided on the side of the limit block 51 away from the limit plate 50 . In this embodiment, a slope structure is selected for the side of the limit block 51 away from the limit plate 50 .

[0037] Furthermore, to avoid accidental separation of the side pad 2 when the user is lying on his / her side, the end of the button 53 away from the limiting plate 50 does not extend beyond the side wall of the side pad 2 , that is, the button 53 is hidden inside the side pad 2 .

[0038] In addition, in order to prevent the foot pad 3 from losing its neutral position fixing effect when it is accidentally detached, a support pad 6 is also included. The support pad 6 can be attached to the surface of the main pad body 1, that is, the support pad 6 has a Velcro hook surface on the side facing the main pad body 1, and the support pad 6 is located between the two foot pads 3.

[0039] The following is the usage of this embodiment:

[0040] First, the two foot pads 3 are symmetrically attached to the side of the main pad body 1 with the furry surface 10, so that the hook surface of the foot pad 3 is attached to the furry surface 10 of the main pad body 1, and the side of the support pad 6 with the hook surface is attached to the furry surface 10 of the main pad body 1, and the support pad 6 is located between the two foot pads 3.

[0041] Then place the foot on the foot pad 3, pull the end of the fixing belt 4 not connected to the foot pad 3, wrap the fixing belt around the ankle and foot, pass the end through the through hole 30 of the foot pad 3, and appropriately tighten the fixing belt 4, and attach the movable end of the fixing belt 4 to the surface of the fixing belt 4 through Velcro. At this point, the assembly of various components required for the supine position is completed, and the main pad body 1 is placed at the foot board of the bed to increase the support effect. After wearing the foot pad, the patient can rest supinely in a neutral position.

[0042] If the patient's condition requires side lying or is used to side lying, the medical staff needs to connect the side pad 2 with the main pad body 1, that is, insert the limit plate 50 and the elastic member 52 into the limit groove 11. When the slope of the limit block 51 contacts the notch of the limit groove 11, the limit blocks 51 on both sides will simultaneously press the elastic member 52 in the middle under the guidance of the slope and as the medical staff continue to apply force, and the elastic member 52 is forced to shrink so that the limit block 51 smoothly enters the limit groove 11. When the limit plate 50 and the elastic member 52 are smoothly inserted into the limit groove 11, the side pad 2 is against one side of the main pad body 1, and the elastic member 52 drives the limit block 51 to reset and be stuck in the limit groove 11, completing the docking of the side pad 2 and the main pad body 1. At this time, the foot can be placed in a neutral position and rest on the side. At the same time, the outer ankle bone of the lower foot is located above the side pad 2, and the inner ankle bone of the lower foot and the inner ankle bone of the upper foot are supported and relieved by the support pad 6.

[0043] If the side pad 2 needs to be removed, the buttons 53 on both sides are pressed at the same time, so that the limiting plates 50 on both sides press the elastic member 52 at the same time. At this time, the side pad 2 can be pulled to bring the limiting plates 50 and the elastic member 52 out of the limiting groove 11, thereby realizing the separation of the side pad 2 and the main pad body 1.

[0044] The above is a preferred embodiment of the present invention. A person skilled in the art may make several modifications and improvements without departing from the principle of the present invention, and these modifications and improvements shall also be regarded as within the protection scope of the present invention.
