Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically to a lower limb airbag foot-lifting pad. Background Technology

[0002] After surgery, patients can elevate their lower limbs slightly above the level of their heart. This helps improve microcirculation, allows the legs to fully relax, and promotes blood return, thereby enhancing blood circulation and reducing the risk of blood clots. This is especially beneficial for patients under general anesthesia, as it can help prevent cramps.

[0003] In the prior art, such as in publication number CN213283984U, a multifunctional lower limb elevating pad is disclosed. It includes a mounting plate with a snap-fit ​​groove on its upper surface. A raised plate is slidably connected to the inner wall of the snap-fit ​​groove. The upper surface of the raised plate has the same snap-fit ​​groove as the upper surface of the mounting plate. A support plate is slidably connected to the inner wall of the snap-fit ​​groove on the upper surface of the raised plate. A protective sleeve is fixedly installed on the upper surface of the support plate. This multifunctional lower limb elevating pad, by adding or removing the number of raised plates according to actual needs, can adjust the height of the pad for greater patient comfort. The protective sleeve prevents the patient's feet from slipping out. The inclusion of a blower, heating rod, and traditional Chinese medicine sterilization tube allows for sterilization and ventilation of the inside of the protective sleeve, maintaining a dry and hygienic environment for the patient's legs, which is beneficial for recovery.

[0004] Although the aforementioned patent can limit the patient's feet and prevent slippage by setting up a protective sleeve, the heel part of the lower limb foot-lifting pad has a certain degree of hardness, which reduces the comfort of postoperative use of the heel and increases the risk of pressure sores; in addition, the foot-lifting pad is easily affected by external forces and will shift, causing changes in the patient's leg posture and affecting the patient's rehabilitation efficiency; therefore, a lower limb airbag foot-lifting pad is proposed to address the above problems. Utility Model Content

[0005] To address the issues that existing lower limb elevating pads have a certain degree of hardness in the heel area, which reduces postoperative comfort and increases the risk of pressure sores; and that the elevating pads are easily affected by external forces and shift, causing changes in the patient's leg posture and affecting the patient's recovery efficiency, this utility model proposes a lower limb airbag elevating pad.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0030] Please see Figures 1-5 As shown, a lower limb airbag foot pad includes a foot pad 1; an outer cover 6 is fitted onto the surface of the foot pad 1, and a Velcro structure 2 is provided on the bottom surface of the outer cover 6. The foot pad 1 has an internal cavity and an airbag assembly 3 is fixedly connected inside the cavity. Fixing assemblies 4 are symmetrically fixedly connected to both sides of the outer cover 6, and a storage bag 5 is fixedly connected to the side of the outer cover 6.

[0031] The airbag assembly 3 includes a base 31 fixedly connected to the cavity. Several airbags 32 are fixedly connected to the surface of the base 31 at equal intervals. An air inlet is opened at one end of the airbag 32. A connecting pipe 33 is fixedly connected to the surface of the air inlet. An air pipe 34 is sleeved at one end of the connecting pipe 33. A pressure relief valve pipe 35 is sleeved at one end of the air pipe 34.

[0032] During operation, a base 31 made of silicone material with anti-slip texture is fixedly installed in the internal cavity of the foot support 1. Multiple independent airbags 32 are arranged in a wave-like pattern along the length of the base 31. Each airbag 32 is connected to an air tube 34 through a connecting tube 33. The end of the air tube 34 is connected to a pressure relief valve tube 35 and a manually pressable inflatable airbag 37. The end of the pressure relief valve tube 35 is sealed to a hose 36 through a rubber ring 7. When in use, airbags 32 are inflated by pressing the inflatable airbag 37. After the airbags 32 expand, they form a flexible support surface. When the patient's heel comes into contact with the wave-like airbags 32, the pressure is dispersed. The elastic deformation of the base 31 further cushions the pressure. When the air pressure inside the airbags 32 is too high, the gas can be released through the pressure relief valve tube 35 to achieve dynamic pressure regulation and reduce the risk of heel pressure sores.

[0033] Furthermore, the fixing component 4 includes a fixing strap 41 and a restraint strap 42 that are fixedly connected to both sides of the outer sleeve 6 respectively. One end of the fixing strap 41 is fixedly connected to a double D buckle 43. The surface of the restraint strap 42 is provided with several sleeve holes. A female buckle 44 is sleeved inside one of the sleeve holes, and a male buckle 45 is sleeved inside the other sleeve holes.

[0034] During operation, fixing straps 41 and restraint straps 42 are sewn on both sides of the outer cover 6. The ends of the fixing straps 41 are fixed with double D buckles 43. The surface of the restraint straps 42 has multiple linearly arranged loop holes. The end loop holes are sewn with female buckles 44, and the remaining loop holes are sewn with male buckles 45. When fixing, the restraint straps 42 are wrapped around the bed frame and then inserted into the double D buckles 43 and pulled tight. Then the ends of the restraint straps 42 are folded back and the female buckles 44 are pressed onto the corresponding male buckles 45. The fixing length is adjusted by the multi-level loop holes to ensure that the foot pads 1 are tightly attached to the bed frame without displacement.

[0035] Furthermore, the bottom of the jacket 6 is provided with a Velcro structure 2, and a storage bag 5 is fixedly connected to the side of the jacket 6.

[0036] When in operation, the Velcro structure on the bottom edge of the outer cover 6 consists of a hook layer and a fleece layer. When cleaning is required, the outer cover 6 can be separated from the foot pad 1 by tearing the Velcro, which is convenient. The storage bag 5 on the middle side of the outer cover 6 has an upward opening and is used to store the inflation balloon 37 or the pressure relief valve tube 35 to prevent the tubes from getting tangled.

[0037] Working principle: After the patient's foot is placed on the surface of the outer cover 6, its gravity acts on the wave-shaped airbags 32 of the airbag assembly 3. After being compressed, the airbags 32 form a connected air chamber with the trachea 34 through the connecting tube 33. The pressure in the air chamber is regulated by the manually pressable inflatable airbag 37: When inflated, gas enters the airbag 32 through the one-way valve to expand it, providing adjustable height flexible support; when the pressure exceeds the threshold, the pressure relief valve tube 35 automatically releases gas to prevent the airbag 32 from being too hard and causing heel pressure. The anti-slip texture and elastic deformation of the silicone base 31 further disperse the pressure on the sole of the foot, forming a double cushion. When the footrest is fixed, the restraint strap 42 goes around the bed frame and passes through the double D buckle 43 of the fixing strap 41 to form a ring restraint. After selecting the appropriate length through the linearly arranged sleeve holes on the surface of the restraint strap 42, the female buckle 44 and the female buckle 45 are fastened to complete the secondary locking, thereby resisting external force displacement. The Velcro structure at the bottom of the jacket 6 detaches during disassembly, facilitating separate washing of the jacket 6. The storage bag 5 centrally stores the inflatable airbag 37 and the air tube 34, ensuring a tidy working environment. This solution simultaneously achieves comfortable foot support and stable device positioning through dynamic airbag pressure adjustment and a dual-fixation mechanism.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
