Description

Technical Field

[0001] This utility model relates to the field of medical and nursing assistive devices, specifically a multifunctional lower limb elevation device. Background Technology

[0002] Foot drop is a common complication in stroke patients undergoing rehabilitation. Foot drop refers to significant weakness in dorsiflexion of the ankle and foot, resulting in the foot slapping the ground when pushing off with the heel during walking. It manifests as an inability to dorsiflex, with the forefoot often hitting the ground during steps, causing patients to frequently trip over themselves. Chronic foot drop can lead to eversion of the foot, making patients more prone to falls and ankle fractures. Chronic foot drop can also lead to Achilles tendon contracture, forming clubfoot, which seriously affects the patient's rehabilitation. In addition, unilateral hemiplegia can easily lead to lower limb circulatory disorders, causing lower limb swelling after exercise.

[0003] Chinese Patent Publication No. CN220801297U discloses a lower limb elevation pad, including a support pad, a base, an anti-slip strip, a first sponge pad, an adhesive adjustment component, and an elevation component. The base is fixedly connected to the bottom surface of the support pad, the anti-slip strip is fixedly connected to the bottom surface of the base, the first sponge pad is fixedly connected to the top surface of the support pad, the adhesive adjustment component is disposed on the top side of the first sponge pad, and the elevation component is installed on the top side of the adhesive adjustment component. The adhesive adjustment component includes a first hook and loop fastener, a second hook and loop fastener, a second sponge pad, and a support frame. The first hook and loop fastener is fixedly connected to the top surface of the first sponge pad, and the top side of the first hook and loop fastener is adhered to the second hook and loop fastener. The second hook and loop fastener is fixedly connected to the bottom surface of the second sponge pad, and the support frame is fixedly connected to the top surface of the second sponge pad.

[0004] However, the aforementioned elevation pads cannot secure the patient's lower limbs during use, and the patient's limbs may slip off the pads. Furthermore, the elevation pads do not relieve the pressure on the patient's legs when the patient places their limbs on them. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of the prior art, which are that the patient's lower limbs cannot be fixed during use, the patient's limbs may slip off the elevation pad, and the elevation pad cannot relieve the pressure on the patient's legs when the patient places their limbs on it.

[0006] A multifunctional lower limb elevation device is proposed, comprising a lower limb pad cover, a sponge pad, a zipper, straps, an anti-sagging plate, airbags, and an inflation assembly. The lower limb pad cover is fitted over the sponge pad. The zipper is located below the lower limb pad cover and connected to it. There are three straps, all located above the lower limb pad cover, and both ends of each strap are connected to the lower limb pad cover. The anti-sagging plate is vertically attached to one end of the lower limb pad cover and located at the center of the lower limb pad cover. There are multiple sets of airbags, all connected above the sponge pad, and each airbag is connected to the inflation assembly, which is connected inside the sponge pad.

[0007] In this invention, the sponge pad has grooves shaped like the shape of the leg, and these grooves are concave. Therefore, when the patient places their lower limb on the sponge pad, it will not easily fall off. The straps wrap around the patient's lower limb after placement and then connect to the sponge pad, thus fixing the sponge pad and the patient's lower limb together and preventing it from falling off. After the straps wrap around the patient's lower limb, the inflation component can be activated to alternately inflate and deflate the airbags, thereby massaging the patient's limb and relieving pressure on the legs. This addresses the shortcomings mentioned in the background section, such as the inability to secure the patient's lower limb during use, the possibility of the patient's limb slipping off the pad, and the pad's inability to relieve pressure on the patient's legs when placed on it.

[0008] In a preferred embodiment of the present invention, the sponge pad is divided into a thigh support area, a knee support area, a calf support area, and an ankle support area. An anti-sagging plate is located at one end of the ankle support area and is attached to the lower limb pad cover. The sponge pad has a placement groove at the position of the thigh support area, so that when the patient is in a side-lying position, the patient can step on the inside of the placement groove.

[0009] In a preferred embodiment of the present invention, the lower limb pad cover is also provided with a groove at the placement slot, and pads are provided on the side walls on both sides of the groove. After the patient places his foot inside the placement slot, the pads will press against the patient's ankle, thereby preventing the patient's ankle from rotating outward or inward.

[0010] In a preferred embodiment of the present invention, a baffle is provided at the bottom of the lower limb pad cover. The baffle is connected to the lower limb pad cover by a zipper. After the sponge pad is placed inside the lower limb pad cover, the baffle can be used to seal the through hole at the bottom of the lower limb pad cover, thereby preventing the sponge pad from falling out of the lower limb pad cover.

[0011] In a preferred embodiment of the present invention, the anti-sagging plate has a U-shaped groove at its top. When the patient places their foot on the sponge pad, the anti-sagging plate can be moved to the end of the patient's tibia (the end near the calcaneus), and then the patient's tibia is placed in the U-shaped groove of the anti-sagging plate, thereby preventing the patient's foot from rotating outward and inward.

[0012] In a preferred embodiment of the present invention, the airbag includes a first airbag and a second airbag. Both the first airbag and the second airbag are positioned above the sponge pad and on opposite sides of the sponge pad, and both the first airbag and the second airbag are connected to an inflation assembly. Each airbag in the support area can be inflated and deflated independently. Therefore, by controlling the airbags, the patient's legs in different support areas can be raised to the required height.

[0013] In a preferred embodiment of the present invention, the inflatable assembly includes a housing, an air pump, a distributor, an air duct, ball valves, butterfly valves, and a control circuit board. The housing is located inside the sponge pad and connected to it. The air pump is connected to one end of the housing and is connected to the distributor via the air duct. A set of ball valves is provided on both sides of the distributor. The distributor is connected to the inlet of the two sets of ball valves via the air duct. The outlet of the ball valves is connected to the air bladder via the air duct. Both sets of ball valves are electrically connected to the control circuit board. The butterfly valve is located at the top of the distributor and connected to the control circuit board. At the top of the air outlet of the inflator, the butterfly valve is electrically connected to the control circuit board, which is connected to one side of the air pump and electrically connected to the air pump. The battery is located on the other side of the air pump and is electrically connected to the air pump, ball valve, butterfly valve, and control circuit board. After the patient's lower limbs are wrapped and fixed with straps, the inflation component can apply different pressures to different parts of the patient by inflating and deflating different airbags. By repeatedly performing the inflation and deflation operations, the patient's lower limbs can be massaged to relieve the pressure on the patient's legs.

[0014] In a preferred embodiment of the present invention, both the ball valve and the butterfly valve are electric valves, and a set of ball valves consists of three valves. After receiving a signal from the control circuit board, the electric valves can automatically complete the corresponding operations without requiring manual operation by the patient, thereby improving the inflation and deflation efficiency of the airbag.

[0015] In a preferred embodiment of the present invention, the straps include a thigh strap, a calf strap, and an ankle strap. One end of the thigh strap and the calf strap are sewn onto the lower limb pad cover, while the other end of the thigh strap and the calf strap are adhered to the lower limb pad cover. One end of the ankle strap is adhered to the lower limb pad cover, while the other end of the ankle strap is connected to the lower limb pad cover via a fastener. The straps can fix the patient's limb to the sponge pad, thereby preventing the patient's limb from falling off the sponge pad.

[0016] In a preferred embodiment of the present invention, the inner side of the ankle strap is connected to an arch support strap. After the anti-sagging plate has been supporting the patient's foot for a long time, the arch support strap and ankle strap can be used to allow the patient to rotate upwards. At this time, the anti-sagging plate can be removed, allowing the patient's shin to be suspended in the air to relieve the pressure on it and thus prevent the formation of pressure sores.

[0017] The advantages of this utility model compared with the prior art are:

[0018] After the patient places their legs on the lower limb pad cover, the ratchet uses straps to connect the patient's legs and the lower limb pad cover together, thus preventing the patient's legs from falling off the sponge pad. The inflation component uses a ball valve to alternately inflate and deflate the two sets of airbags. When the airbags inflate, they compress the patient's limbs, and when the airbags deflate, the pressure on the limbs disappears. Therefore, when the two sets of airbags alternately inflate and deflate, they can alternately press on the patient's lower limbs, thereby relieving the pressure on the patient's lower limbs.

Detailed Implementation

[0031] The following will refer to the appendix in the embodiments of this utility model. Figure 1-11 The technical solutions in the embodiments of this utility model are described in detail.

[0032] like Figure 1-4 As shown, a multifunctional leg-elevating device includes a lower limb pad cover 1, a sponge pad 2, a zipper 3, a strap 4, an anti-sagging plate 5, an airbag 6, and an inflation component 7. The lower limb pad cover 1 is supported by a cloth cover, which has a certain elastic deformation capacity. Therefore, when the airbag 6 is inflated, the lower limb pad cover 1 will bounce upward with the gradually expanding body shape of the airbag 6, thereby transmitting the upward pressure brought by the expansion of the airbag 6 to the patient's limb.

[0033] like Figure 1-4 As shown, after the lower limb pad cover 1 is used up, the sponge pad 2 can be removed and the lower limb pad cover 1 can be cleaned and disinfected to avoid cross-infection. The sponge pad 2 is placed inside the lower limb pad cover 1. The sponge pad 2 used can be a high-density S-shaped sponge pad 2. This type of sponge pad 2 has strong support and high comfort, thereby relieving the patient's leg discomfort as much as possible. The lower limb pad cover 1 has a through hole at the bottom. The zipper 3 is located at the through hole at the bottom of the lower limb pad cover 1 and is connected to the leg pad cover.

[0034] like Figure 1-4As shown, the baffle 13 is located at the through hole below the lower limb pad cover 1. One side of the baffle 13 is sewn onto the lower limb pad cover 1, and the remaining three sides of the baffle 13 are connected to the lower limb pad cover 1 via a zipper 3. Therefore, when needed, the zipper 3 can be opened to expose the through hole below the lower limb pad cover 1, and then the sponge pad 2 can be inserted into the lower limb pad cover 1 through the through hole below the lower limb pad cover 1. Subsequently, the baffle 13 and the lower limb pad cover 1 can be connected together using the zipper 3 to seal the through hole below the lower limb pad cover 1, thereby preventing the sponge pad 2 from falling out of the through hole below the lower limb pad cover 1.

[0035] like Figure 1-4 As shown, the lower limb pad cover 1 has a groove 11 at the position of the thigh support area 21, and the sponge pad 2 also has a placement groove 25 at the position of the groove 11. A pad block 12 is attached to the side wall on both sides of the groove 11. The pad block 12 is made of silicone material. When the patient is in a side-lying position, the patient can step on the inside of the placement groove 25. After the patient steps on the inside of the placement groove 25, the pad block 12 can support the patient's foot from both sides of the ankle, thereby preventing the patient's foot from rotating inward or outward.

[0036] like Figure 1-4 As shown, there are three straps 4, all vertically positioned above the lower limb pad cover 1. The three straps 4 are arranged along the length of the lower limb pad cover 1. One end of each strap 4 is connected to the lower limb pad cover 1. Therefore, after the patient places their leg on the sponge pad 2, the straps 4 can be used to connect the patient's leg and the lower limb pad cover 1 together, thereby preventing the patient's leg from falling off the sponge pad 2. The anti-sagging plate 5 is vertically positioned at one end of the lower limb pad cover 1 and located at the top of the lower limb pad cover 1. The anti-sagging plate 5 is attached to the outer surface of the lower limb pad cover 1 by Velcro.

[0037] like Figure 1-4 As shown, the position and height of the anti-sagging plate 5 can be adjusted according to usage needs, and the anti-sagging plate 5 can be removed directly when not needed. The top of the anti-sagging plate 5 has a U-shaped groove, so after the patient places their leg on the sponge pad 2, the anti-sagging plate 5 can be moved to the bottom of the patient's foot. After the anti-sagging plate 5 is moved to the end of the patient's tibia (the end near the calcaneus), the posterior triangular bone of the talus at the end of the patient's tibia can be placed inside the U-shaped groove.

[0038] like Figure 1-4 As shown, this allows the anti-sagging plate 5 to support the posterior triangle of the talus in the patient's leg, thereby supporting the patient's foot with the posterior triangle of the talus. This ensures that the patient's foot does not sag while the heel is suspended in the air. Furthermore, by using the U-shaped groove to lock the posterior triangle of the talus, the patient's foot can be prevented from internally or externally rotating.

[0039] like Figure 1-4 As shown, there are two sets of airbags 6, both of which are set above the sponge pad 2. Both sets of airbags 6 are adhered to the upper surface of the sponge pad 2. At the same time, both sets of airbags 6 are connected to the inflation component 7, which is located inside the sponge pad 2. When the inflation component 7 is working, it can input gas into the interior of the airbags 6, thereby causing the airbags 6 to inflate upward.

[0040] like Figure 1-4 As shown, the straps 4 include thigh straps 41, calf straps 42 and ankle straps 43, and the thigh straps 41, calf straps 42 and ankle straps 43 are located in the thigh support area 21, calf support area 23 and ankle support area 24 of the sponge pad 2, respectively. One end of the thigh straps 41 and calf straps 42 are sewn onto the lower limb pad cover 1, and the other end of the thigh straps 41 and calf straps 42 are attached to the lower limb pad cover 1 with Velcro. Therefore, after the patient places their leg on the sponge pad 2,

[0041] like Figure 1-4 As shown, the ends of the thigh strap 41 and calf strap 42 with Velcro can be wrapped around the patient's leg and attached to the lower limb pad cover 1. It is important to ensure that when the ends of the thigh strap 41 and calf strap 42 are attached to the lower limb pad cover 1, the inner walls of the thigh strap 41 and calf strap 42 are in complete contact with the patient's leg. In this way, the patient's leg is connected to the sponge pad 2 and the lower limb pad cover 1, while preventing the patient's leg from falling off the sponge pad 2.

[0042] like Figure 1-4 As shown, one end of the ankle strap 43 is also attached to the lower limb pad cover 1 using Velcro, while the other end of the ankle strap 43 is connected to the lower limb pad cover 1 through a fixing buckle 8. A screw is attached to the lower limb pad cover 1 at the position of the fixing buckle 8. The inner wall of the fixing buckle 8 is threaded, so after the fixing buckle 8 passes through the pre-set through hole of the ankle strap 43, it can be connected to the screw by the thread.

[0043] like Figure 1-4 As shown, the ankle strap 43 can rotate around the axis of the screw. After the patient places their leg on the sponge pad 2, the end of the ankle strap 43 with Velcro can be wrapped around the patient's ankle and attached to the lower limb pad cover 1. It is important to ensure that the inner wall of the ankle strap 43 is in contact with the patient's ankle. An arch strap 44 is sewn onto the inner wall of the ankle strap 43.

[0044] like Figure 1-4As shown, the two ends of the arch support 44 can be glued together with Velcro. After using the anti-sagging plate 5 to support the patient's foot for a long time, the anti-sagging plate 5 can be removed. Then, rotate the ankle strap 43 until the patient's arch can be placed on the inner wall of the arch support 44. Then, the two ends of the arch support 44 can be wrapped around the sides of the patient's arch and glued together with Velcro at the instep of the patient.

[0045] like Figure 1-4 As shown, the patient's foot can then be rotated upwards around the protruding ankle bone on the outside of the ankle. After rotating the patient's foot to the desired position, the end of the ankle strap 43 with Velcro can be attached to the lower limb pad cover 1 to restrict the position of the patient's foot. At this time, the position where the anti-sagging plate 5 was originally pressed against is now suspended, thereby relieving the pressure on the foot and preventing the formation of pressure sores.

[0046] like Figure 5-7 As shown, the sponge pad 2 is divided into a thigh support area 21, a knee support area 22, a calf support area 23, and an ankle support area 24. Different support areas are used to support different positions of the patient's thigh. The anti-sagging board 5 is vertically set at one end of the ankle support area 24 and is attached to the lower limb pad cover 1. The sponge pad 2 has a placement groove 25 at the position of the thigh support area 21. When the patient is in a side-lying position, the patient can step on the inside of the placement groove 25, thereby avoiding hard contact between the patient's foot and the bed board.

[0047] like Figure 5-7 As shown, the airbag 6 includes a first airbag 61 and a second airbag 62. The first airbag 61 and the second airbag 62 are both located above the sponge pad 2 and on both sides of the sponge pad 2 respectively. The first airbag 61 and the second airbag 62 are both connected to the inflation component 7. The lower surfaces of the two sets of airbags 6 are both adhered to the sponge pad 2. Therefore, when the airbag 6 expands and deforms, the airbag 6 can only push upwards, thereby applying the upward pressure of the airbag 6 to the patient's leg through the lower limb pad cover 1.

[0048] like Figure 5-7 As shown, both sets of airbags 6 are connected to the inflation component 7, so both sets of airbags 6 can be inflated and deflated independently, thereby applying different pressures to different positions of the patient's leg. When the height of the sponge pad 2 is insufficient, air can be inflated into the airbag 6, thereby expanding it upwards to raise the height of the patient's leg.

[0049] like Figure 8-11As shown, the inflation assembly 7 includes a housing 71, an air pump 72, a distributor 73, an air duct 74, a ball valve 75, a butterfly valve 76, a control circuit board 77, and a battery 78. The housing 71 is disposed inside the sponge pad 2 and adhered to the sponge pad 2. The air pump 72 is disposed inside the housing 71 and fixed to one end of the housing 71 by screws. The air outlet of the air pump 72 is connected to the distributor 73 through the air duct 74. The distributor 73 is disposed at the other end of the housing 71 and adhered to the bottom plate of the housing 71. A set of ball valves 75 is provided on both sides of the distributor 73, and the air outlets of the two sets of ball valves 75 are respectively connected to the first airbag 61 and the second airbag 62 through the air duct 74.

[0050] like Figure 8-11 As shown, the ball valves 75 used are electric valves, and both sets of ball valves 75 are electrically connected to the control circuit board 77. The air inlets of both sets of ball valves 75 are connected to the air outlets on both sides of the distributor 73 through the air guide pipe 74. Therefore, the gas generated when the air pump 72 is working will be diverted by the distributor 73 and then input into the interior of the ball valve 75 through the air guide pipe 74. There are three ball valves 75 in one set, and the three ball valves 75 are connected to the airbags 6 of the three support areas on the sponge pad 2 through the air guide pipe 74 respectively.

[0051] like Figure 8-11 As shown, the control circuit board 77 can individually inflate and deflate each airbag 6 on the sponge pad 2 via the ball valve 75. The butterfly valve 76 is located above the distributor 73 and is set in the air outlet above the distributor 73. The butterfly valve 76 is also an electric valve, and the butterfly valve 76 is electrically connected to the control circuit board 77. Therefore, when the ball valve 75 is opened by the control circuit board 77 to perform the deflation operation, the butterfly valve 76 will also be opened, and the air inside the airbag 6 can be discharged through the butterfly valve 76 after flowing back to the distributor 73.

[0052] like Figure 8-11 As shown, when the ball valve 75 is opened by the control circuit board 77 for inflation, the butterfly valve 76 will also be closed. The control circuit board 77 is located on one side of the air pump 72 and is electrically connected to the air pump 72. The control circuit board 77 is also attached to the bottom plate of the housing 71. Therefore, the control circuit board 77 can directly start or stop the air pump 72. The battery 78 is located on the other side of the air pump 72 and is electrically connected to the ball valve 75, the butterfly valve 76, the air pump 72 and the control circuit board 77. Therefore, the battery 78 can directly supply power to the ball valve 75, the butterfly valve 76, the air pump 72 and the control circuit board 77.

[0053] like Figure 8-11As shown, after the patient places their leg on the sponge pad 2 for an extended period, the control circuit board 77 can be used to activate the air pump 72. The control circuit board 77 then alternately activates the two sets of ball valves 75 to perform alternating inflation and deflation operations on the two sets of airbags 6. Specifically, when the ball valve 75 of the first airbag 61 is open, the ball valve 75 of the second airbag 62 is closed. Therefore, the airflow generated by the air pump 72 during operation will enter the interior of the first airbag 61 through the ball valve 75. After the first airbag 61 completes the process of inflating and pressing the patient's limb, the air pump 72 is turned off and the butterfly valve 76 is opened, allowing the air inside the first airbag 61 to be discharged through the butterfly valve 76 and the diverter 73.

[0054] like Figure 8-11 As shown, after the air inside the first airbag 61 is completely expelled through the butterfly valve 76, the butterfly valve 76 and the ball valve 75 belonging to the first airbag 61 are closed. Then, the ball valve 75 belonging to the second airbag 62 and the air pump 72 are opened. At this time, the air pump 72 will input the generated airflow into the interior of the second airbag 62. After the second airbag 62 completes the process of inflating and pressing the patient's limb, the air pump 72 is closed and the butterfly valve 76 is opened, allowing the air inside the second airbag 62 to be expelled through the butterfly valve 76 and the diverter 73.

[0055] like Figure 8-11 As shown, after the air inside the second airbag 62 is completely expelled through the butterfly valve 76, the butterfly valve 76 and the ball valve 75 belonging to the second airbag 62 are closed. Then, the ball valve 75 belonging to the first airbag 61 is opened and the air pump 72 is turned on to inflate the first airbag 61. This process is then repeated. When the airbag 6 inflates, it will compress the patient's limbs. When the airbag 6 deflates, the pressure on the limbs will disappear. Therefore, when the two sets of airbags 6 are inflated and deflated in turn, they can press on the patient's limbs in turn, thereby relieving the pressure on the patient's legs.

[0056] The movement process in this embodiment is as follows: After the sponge pad 2 is placed inside the lower limb pad cover 1, the zipper 3 is pulled to connect the baffle 13 and the lower limb pad cover 1 together. Then, the sponge pad 2 is placed on the hospital bed and the patient's lower limbs are placed on the sponge pad 2. Then, the end of the strap 4 with Velcro is wrapped around the patient's lower limbs and attached to the lower limb pad cover 1. Then, the position of the anti-sagging plate 5 is adjusted so that the anti-sagging plate 5 supports the position of the patient's posterior triangular bone of the talus.

[0057] The anti-sagging plate 5 can be glued to the lower limb pad cover 1. After the anti-sagging plate 5 has been supporting the patient for a period of time, the anti-sagging plate 5 can be removed and the ankle strap 43 can be rotated. After the arch strap 44 is wrapped around the patient's foot and the patient's foot is rotated upward to the desired position, the end of the ankle strap 43 can be glued to the lower limb pad cover 1. Then, the inflation component 7 is activated to alternately inflate and deflate the first airbag 61 and the second airbag 62 to alternately press on the patient's lower limbs, thereby relieving the pressure on the patient's legs.

[0058] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
