Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold compress technology, and in particular to a novel foot cold compress and elevation pad device. Background Technology
[0002] In foot care and treatment, cold compresses and elevation are commonly used methods. Cold compresses can reduce inflammation and swelling and improve blood circulation, while elevation helps reduce blood pooling in the lower limbs and relieve discomfort.
[0003] Existing methods typically involve placing ice packs directly on the feet or filling cloth bags with ice. However, these methods have limitations in maintaining the ice pack's position and improving the cooling effect. Furthermore, users need to frequently adjust the position and distance of the ice pack. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a novel foot cooling and elevation pad device, which solves the technical problems of existing ice packs being inconvenient to use and difficult to dynamically adjust.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel foot cooling and elevating pad device, comprising:
[0006] The leg support pad has a concave top that forms an arc-shaped support surface suitable for supporting the lower limbs;
[0007] A pair of ice packs are symmetrically arranged on the inner side of the support leg pads;
[0008] An elastic protruding airbag is located in the middle region of the arc-shaped bearing surface, and its top height is higher than the reference plane of the arc-shaped bearing surface. When the leg is pressed, it is deformed by pressure and generates compressed airflow.
[0009] An air duct, embedded inside the outrigger pad, forms a gas passage from the elastic protruding airbag to the ice pack areas on both sides.
[0010] A pair of elastic side pressure airbags are fixed between the ice pack and the inner side of the outrigger pad, and form a closed air passage through the air duct and the elastic protruding airbag.
[0011] When the elastic protruding airbag is subjected to pressure from the lower limb, it generates a directional airflow. The airflow passes through the air duct, causing the elastic side pressure airbag to expand radially, pushing the ice pack towards the surface of the limb and forming a dynamic pressing force.
[0012] Preferably, the dynamic clamping force is adaptively adjusted according to the pressure changes of the lower limb. When the pressure on the elastic protruding airbag increases, the radial expansion of the elastic side pressure airbag increases accordingly, so that the clamping force between the ice pack and the limb surface increases in a positive correlation.
[0013] Preferably, the expansion stroke of the elastic side pressure airbag is controlled by the airflow pressure in the air duct, maintaining a constant compression force when the leg is stationary, and generating pulsed pressure fluctuations when the leg moves.
[0014] Preferably, the contact surface between the ice pack and the limb surface is provided with a pressure distribution structure, including:
[0015] The array of protrusions forms a multi-point clamping force zone during compression;
[0016] The airflow channels surrounding the raised points maintain air circulation in the cooling area during cold compresses.
[0017] Preferably, the wall thickness of the elastic side-pressure airbag near the contact side containing the ice pack is less than the wall thickness of the back side, so that it produces directional deformation towards the limb when it expands.
[0018] By means of the above technical solution, this utility model provides a novel foot cooling and elevation pad device, which has at least the following beneficial effects:
[0019] 1. This utility model can automatically adjust the fit of the cold compress according to the leg pressure, improve comfort and cold compress effect, and ensure that the ice pack is always in close contact with the skin through dynamic air path, avoiding the cold compress from shifting due to limb movement, and realizing adaptive cold compress pressure.
[0020] 2. The addition of raised dots in this utility model can disperse pressure, and the drainage channel maintains breathability, avoiding the stuffy feeling of traditional cold compress pads. At the same time, the gradual wall thickness design of the elastic side pressure airbag ensures that the pressure is concentrated on the limb, improving the efficiency of cold compress. The combination of raised dots and drainage channel for microenvironment control achieves a balance between comfortable cold compress and stable pressure. Attached Figure Description

[0025] 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 protection scope of the present utility model.
[0026] Please refer to Figures 1-2 This embodiment proposes a novel foot cooling and elevation pad device, comprising:
[0027] The leg pad 1 has a concave top forming an arc-shaped bearing surface suitable for supporting the lower limbs;
[0028] A pair of ice packs 2 are symmetrically arranged on the inside of the support leg pad 1. The ice packs 2 are equipped with zippers, and the ice packs can be loaded and unloaded by opening and closing the zippers.
[0029] The elastic protruding airbag 3 is located in the middle area of the arc-shaped bearing surface, and its top height is higher than the reference plane of the arc-shaped bearing surface. When the leg is pressed, it is deformed by pressure and generates compressed airflow.
[0030] The air duct 4 is embedded inside the outrigger pad 1, forming a gas passage from the elastic protruding airbag 3 to the area where ice packs 2 are placed on both sides.
[0031] A pair of elastic side pressure airbags 5 are respectively fixed between the ice pack 2 and the inner side of the support leg pad 1, and form a closed air passage with the elastic protruding airbag 3 through the air duct 4.
[0032] When the elastic protruding airbag 3 is subjected to pressure from the lower limb, it generates a directional airflow. The airflow passes through the air duct 4, causing the elastic side pressure airbag 5 to expand radially, pushing the ice pack 2 to move towards the surface of the limb and forming a dynamic pressing force.
[0033] The curved support surface of the leg support pad 1 provides stable lower limb support, keeping the legs elevated and promoting blood circulation. Ice packs 2 are fitted to both sides of the lower limbs, providing basic cooling. When the patient places their lower limbs on the leg support pad 1, the legs naturally press against the elastic protruding air bladders 3, compressing and deforming them, squeezing out the internal air. The compressed airflow is transmitted through the air tube 4 to the elastic side pressure air bladders 5 on both sides. After entering the elastic side pressure air bladders 5, the airflow causes them to expand radially, pushing the ice packs 2 towards the surface of the limb.
[0034] like Figure 2 As shown, based on the elastic properties of the airbag, the compression force of the ice pack 2 is dynamically adjusted according to the leg pressure:
[0035] The greater the pressure (such as when the patient adjusts their posture or the weight of their legs increases), the greater the compression of the elastic protruding airbag 3, the stronger the airflow, the more pronounced the expansion of the elastic side pressure airbag 5, and the greater the pressure of the ice pack 2, ensuring a tighter fit for the cold compress.
[0036] When the pressure decreases (e.g., the leg is slightly raised), the elastic protruding airbag 3 partially rebounds, the airflow weakens, the elastic side pressure airbag 5 contracts, and the pressure of the ice pack 2 decreases to avoid excessive compression.
[0037] With constant pressure (such as in a static posture), the elastic protruding airbag 3 can maintain a constant air pressure, ensuring that the ice pack 2 remains stably attached to the limb and preventing the cold compress from shifting.
[0038] During leg movements (such as micro-adjustment of posture), the elastic protruding airbag 3 generates pulsed airflow, causing the elastic lateral pressure airbag 5 to dynamically adjust its expansion degree to adapt to limb movement and avoid pressure discomfort.
[0039] The dynamic compression force adapts to changes in lower limb pressure. When the pressure on the elastic protruding airbag 3 increases, the radial expansion of the elastic lateral pressure airbag 5 increases accordingly, so that the compression force between the ice pack 2 and the limb surface increases in a positive correlation.
[0040] The expansion stroke of the elastic side pressure airbag 5 is controlled by the airflow pressure in the air duct 4, maintaining a constant pressure when the legs are stationary, and generating pulse-like pressure fluctuations when the legs move.
[0041] like Figure 2 As shown, the contact surface between the ice pack 2 and the limb surface is provided with a pressure distribution structure, including:
[0042] The array of protrusions forms a multi-point clamping force zone during compression.
[0043] The raised dots create a multi-point pressure zone. When the elastic side pressure airbag 5 expands and pushes the ice pack 2 against the limb, the raised dots first contact the skin, forming a discrete pressure distribution. This avoids large-area hard pressure and improves comfort. The array arrangement of the raised dots (such as honeycomb or matrix) optimizes pressure dispersion and prevents excessive local pressure from obstructing blood circulation. Because the skin temperature decreases during cold compresses, the raised dot structure reduces the direct transmission of cold sensation, thus reducing discomfort.
[0044] The airflow channels surrounding the raised points maintain air circulation in the cooling area during cold compresses.
[0045] The airflow channels between the raised dots create airflow passages, allowing the skin in the cold compress area to remain in contact with air, preventing moisture buildup caused by complete sealing. Air circulation helps to evenly dissipate heat, prevents condensation buildup, and improves the comfort of the cold compress. During pressurized cold compresses, the airflow channels allow a small amount of air to pass through, avoiding a vacuum suction effect and facilitating the adjustment of the ice pack's position with slight limb movements.
[0046] The wall thickness of the elastic lateral pressure airbag 5 on the contact side near the ice pack 2 is less than that on the back side, causing directional deformation towards the limb when it inflates.
[0047] The elastic side-pressure airbag 5 employs a gradually thickening wall design (thin on the contact side, thick on the back side), resulting in directional selective expansion behavior. When airflow enters the elastic side-pressure airbag 5 from the air duct 4, the internal pressure of the airbag 5 increases. Due to the thinner wall on the contact side, this area is more prone to preferential deformation, while the thicker back side deforms less. This design concentrates the expansion force towards the limb, rather than uniformly expanding radially, thereby precisely pushing the ice pack 2 to adhere to the skin and reducing ineffective deformation. When leg pressure changes, the thin-walled side of the elastic side-pressure airbag 5 responds quickly to pressure changes, achieving instant pressure adjustment and ensuring that the ice pack 2 always adheres tightly without excessive pressure. The thick back side structure provides support stability, preventing the elastic side-pressure airbag 5 from ineffectively expanding towards the leg pad 1 and improving energy transfer efficiency.
[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
