Description

Technical Field

[0001] This invention relates to the field of orthopedic cold compresses, and in particular to a splint for applying traditional Chinese medicine orthopedic compresses. Background Technology

[0002] In the field of traditional Chinese medicine orthopedics, cold compresses, as an important physical therapy method, occupy a pivotal position and are widely used in the treatment of various orthopedic conditions.

[0003] Fractures are a common orthopedic condition. After a fracture, the injured site will experience bleeding, congestion, swelling, and inflammation. Applying cold compresses can lower the local temperature, causing vasoconstriction and reducing blood flow to the injured area, effectively controlling bleeding and swelling. For example, in the case of a lower leg fracture, timely cold compresses can significantly reduce swelling, creating favorable conditions for subsequent treatments such as reduction and fixation, promoting healing, and reducing the likelihood of complications.

[0004] Soft tissue injuries are also common problems in orthopedics, such as sprains and strains. When a soft tissue injury occurs, applying cold compresses can constrict local blood vessels, inhibit secondary swelling of the affected area, prevent further rupture of capillaries, reduce abnormal bleeding, and also numb nerves, effectively relieving pain. For example, in the case of an ankle sprain, applying cold compresses immediately after the injury can greatly reduce swelling and pain, and shorten recovery time.

[0005] Cold compresses can also inhibit the release of inflammatory mediators and reduce inflammatory responses, thus having a positive therapeutic effect on some inflammation-related orthopedic conditions. In the postoperative stage of orthopedic surgery, cold compresses help stop bleeding, reduce swelling, relieve pain, and decrease the probability of bruising, promoting postoperative recovery and allowing patients to begin rehabilitation training as early as possible.

[0006] Traditional cold compress materials, primarily ice packs, have several significant shortcomings. The temperature of ice packs is difficult to control precisely. Initially, the temperature often drops rapidly, potentially causing excessively low temperatures and frostbite. As time passes, the temperature rises quickly, making it difficult to maintain an effective cooling temperature range and provide a stable low-temperature environment for treatment. The effective cooling area is typically small, failing to fully cover large wounds. For irregularly shaped wounds or extensive swelling, the ice pack's fit is poor, significantly reducing its effectiveness. Traditional ice packs also present challenges in fixation, easily shifting during use and hindering sustained application to the injured area, thus affecting the continuity of treatment.

[0007] Traditional medicated splints also have shortcomings in terms of materials and structure. Most splints are made of rigid materials with extremely poor breathability. Prolonged wear can create a hot and humid environment for the patient's skin, increasing the likelihood of skin allergies, itching, and other discomforts, and reducing patient compliance. These splints are often fixed in shape and cannot adapt well to changes in limb shape. During immobilization, they may exert uneven pressure on the limb, affecting blood circulation and potentially leading to local tissue ischemia and necrosis. Furthermore, traditional splints restrict the normal range of motion of joints, hindering early rehabilitation training.

[0008] Therefore, there is an urgent need in this field for a novel cold compress device for orthopedic trauma to solve the problems in the existing technology. Summary of the Invention

[0009] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide a splint for applying medicine in traditional Chinese orthopedics.

[0010] The technical solution of the present invention is as follows: A splint for applying medicine in traditional Chinese orthopedics, characterized in that it comprises:

[0011] Circulating cold compress unit;

[0012] A flexible cold compress plate, comprising an inner contact layer, a skeleton layer, a water bladder layer, and an outer protective layer;

[0013] The water bladder layer is a flexible layer. The water bladder layer is hollow inside and defines a one-way water flow path. The water flow path is connected to the circulating cold compress host through a circulation pipe. One end of the water bladder layer is provided with a first connector and the other end is provided with a second connector. The first connector and the second connector are detachably connected so that the water bladder layer is fixed at the limb injury site.

[0014] The skeleton layer is provided on the side of the water sac layer closest to the human limb. The skeleton layer is an adaptive layer that can be softened or hardened by temperature changes.

[0015] The skeleton layer has a detachable inner contact layer on the side closest to the human limb. A medicated patch is attached to the center of the inner contact layer. The inner contact layer has micro-grooves for guiding condensate to the edge.

[0016] The outer protective layer is provided on the side of the water sac layer away from the human limb. The outer protective layer includes an inner film layer, an outer film layer and a middle mesh layer. The inner film layer, the outer film layer and the mesh layer together define a number of closed cavities that are not interconnected. Each cavity is filled with a volatile liquid.

[0017] When no cold water is introduced into the water bladder layer and it is at the first temperature, the skeleton layer softens to form a curved surface that conforms to the limb, the liquid in the cavity evaporates into gas, and the outer protective layer is in a soft and expanded state.

[0018] When cold water is introduced into the water bladder layer and maintained at a second temperature lower than the first temperature, the skeleton layer is in a rigid state, the gas in the cavity condenses into liquid due to the low temperature, and the outer protective layer is in a tight state flattened by atmospheric pressure.

[0019] Furthermore, the first connector and the second connector are detachable buckle assemblies.

[0020] Furthermore, the detachable fastener assembly is one of Velcro, magnetic, or mechanical fasteners.

[0021] Furthermore, a first magnetic attractor is provided on the side edge of the water bladder layer near the inner contact layer, and a second magnetic attractor is provided on the side edge of the inner contact layer near the water bladder layer. The first magnetic attractor and the second magnetic attractor are magnetically attracted to each other to fix the inner contact layer.

[0022] Furthermore, the inner contact layer is made of a thermally conductive material.

[0023] Furthermore, the surface of the inner contact layer is a hydrophilic surface.

[0024] Furthermore, the skeleton layer is a shape memory polymer layer.

[0025] Furthermore, the inner thin film layer is a thermally conductive layer, and the outer thin film layer is a thermally insulating layer.

[0026] Furthermore, a partition rib is provided in the middle of the water bladder layer, which divides the internal space of the water bladder layer into an inflow cavity and an outflow cavity on both sides. The partition rib is provided with a guide port for connecting the inflow cavity and the outflow cavity to form the water flow path. Several staggered flow-blocking ribs are provided in both the inflow cavity and the outflow cavity. The water bladder layer is provided with an inlet pipe and an outlet pipe. The inlet pipe is connected to the inflow cavity, and the outlet pipe is connected to the outflow cavity. The inlet pipe and the outlet pipe are connected to the circulation pipeline.

[0027] Furthermore, the circulating cold compress host includes a temperature control cooling module, a circulation flow module, and a central control interaction module. The circulation flow module is used to circulate cold compress water to the water bladder layer. The temperature control cooling module is used to perform low-temperature cooling and temperature regulation of the cold compress water. The central control interaction module is used for human-computer interaction and to control the temperature control cooling module and the circulation flow module.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] 1. A collaborative working mechanism of "triple intelligent response" has been realized: the device is not a passive container, but an intelligent system that can actively change its physical properties according to temperature;

[0030] (1) Stiffness response of the skeleton layer: Based on the phase change characteristics of shape memory polymer, "hard support at low temperature and soft fit at high temperature" is realized, which is the core of adaptive fixation, taking into account both stable fixation during treatment and comfortable fit during the interval.

[0031] (2) Volume / density response of the outer protective layer: Through the controllable gas-liquid phase change of the internal medium, "tight wrapping at low temperature and loose expansion at high temperature" is achieved, which, together with the skeleton layer, forms a highly rigid protective structure when cold-applied.

[0032] (3) Fluid management response of the inner contact layer: Through the combination of micro-grooves and hydrophilic materials, the condensate is actively guided, which completely solves the problem of skin immersion during the cold compress process and improves safety and comfort.

[0033] 2. Innovatively solves the problem of condensate management: The "active flow guidance" design of the inner contact layer transforms the traditional "blocking" approach into "dredging," greatly eliminating the adverse effects of condensate and significantly improving the user experience.

[0034] 3. A highly efficient system architecture combining active and passive loops was constructed:

[0035] Active circulation system: Composed of the main unit and water bladder layer, it provides continuous, controllable, and uniformly temperatured precise cryotherapy, ensuring treatment effectiveness.

[0036] Passive adaptive system: Composed of a skeleton layer and an outer protective layer, it does not require external energy to drive it. It can intelligently adjust the stiffness, shape and encapsulation of the overall structure by relying solely on natural temperature changes before and after treatment, thus achieving adaptive optimization of the fixation effect.

[0037] 4. Modular and humanized design: The flexible cold compress has a multi-layer structure that is removable and washable (such as the inner contact layer), and the connectors are easy to wear. The overall design fully considers the convenience of clinical use, hygiene requirements, and long-term patient comfort.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] In the description of this invention, "first feature" and "second feature" may include one or more of the indicated features. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of the indicated features.

[0058] Please refer to the attached diagram below. Figures 1-8 A traditional Chinese medicine orthopedic splint according to an embodiment of the present invention is described. The device includes a circulating cold compress host 1 and a flexible cold compress plate.

[0059] like Figure 1As shown, the circulating cold compress unit 1 includes a temperature control cooling module, a circulation module, and a central control interaction module. The circulation module drives the cold compress water to circulate within the system; the temperature control cooling module precisely cools and regulates the temperature of the circulating cold compress water; the central control interaction module integrates the control unit and the human-machine interface for parameter setting, mode selection, and system operation status display, and uniformly controls the operation of the temperature control cooling module and the circulation module. This active circulation system ensures a continuous, stable, and uniform cold compress temperature, overcoming the shortcomings of traditional ice packs where the temperature drops suddenly and is difficult to maintain.

[0060] like Figures 2-5 As shown, the flexible cold compress is the core functional component that comes into direct contact with the patient's limbs. It has a multi-layered composite structure, which includes an inner contact layer 2, a skeleton layer 3, a water bladder layer 4, and an outer protective layer 5 from the side closest to the limb outwards.

[0061] The water-filled layer 4 is a sealing layer made of flexible polymer material, hollow inside and defining a one-way water flow path. This water flow path is connected to the circulating cold compress host 1 through the circulation pipe 11, forming a closed active circulating cooling circuit. One end of the water-filled layer 4 is provided with a first connector 41, and the other end is provided with a second connector 42. The first connector 41 and the second connector 42 are detachably connected (e.g., using Velcro, magnetic snaps, or mechanical fasteners), allowing the entire flexible cold compress plate to be easily wrapped around and fixed to the limb injury site.

[0062] The water sac layer 4 has a skeleton layer 3 on the side closest to the human limb. The skeleton layer 3 is made of shape memory polymer, which is an adaptive layer that can change in softness or hardness in response to temperature changes.

[0063] Specifically, the skeleton layer 3 is preferably made of polyurethane-based shape memory polymer, and its glass transition temperature is designed to be between 10-15°C, depending on the required cooling temperature. When the cooling compress begins, circulating cold water lowers the temperature below its glass transition temperature (e.g., 10°C), the material maintains its glassy rigidity, providing stable support and pressure to the affected area, which helps reduce swelling. When the cooling compress ends and the material temperature rises above room temperature or other conditions higher than the cooling temperature, it enters a highly elastic state, becoming soft and easy to remove the device.

[0064] A removable inner contact layer 2 is provided on the side of the skeletal layer 3 closest to the human limb. A medicated patch 22 is adhered to the center of the inner contact layer 2. Different traditional Chinese medicine patches (such as safflower and angelica for promoting blood circulation and removing blood stasis, and frankincense and myrrh for reducing swelling and relieving pain) can be changed according to the TCM syndrome type of the fracture / sprain (e.g., blood stasis and qi stagnation type, cold-dampness obstruction type) to reduce swelling and relieve pain. The inner contact layer 2 can be made of, for example, highly thermally conductive medical silicone or hydrogel, with a hydrophilic surface treatment, and the surface of the inner contact layer 2 has microgrooves for guiding condensate to the edges. These grooves can be designed, for example, as a leaf vein-like network radiating from the center of the contact layer to the surrounding edges, with a width and depth on the order of micrometers to sub-millimeters.

[0065] Based on the principle of capillary action, when the condensate generated on the outer surface of the water bladder layer 4 during the cold compress comes into contact with this hydrophilic surface, it will be quickly captured by the grooves and guided along the grooves to the edge of the flexible cold compress plate and evaporate. This fundamentally solves the risk of skin maceration, discomfort or even frostbite caused by the accumulation of condensate, and realizes an experience upgrade from "passive waterproofing" to "active diversion".

[0066] The side of the water sac layer 4 furthest from the human limb is provided with an outer protective layer 5. The outer protective layer 5 includes an inner thin film layer 51, an outer thin film layer 52, and a mesh layer 53 sandwiched in between. The inner thin film layer 51, the outer thin film layer 52, and the mesh layer 53 are heat-sealed or bonded together to define several non-interconnected honeycomb-shaped closed cavities. Each cavity is filled with a volatile liquid with a specific boiling point, such as an environmentally friendly alkane solvent with a boiling point of around 15°C.

[0067] Its working principle is as follows: When the device is not in use or at a temperature higher than the cooling temperature, such as room temperature, the liquid evaporates into gas, causing the cavity to expand. The outer protective layer 5 is in a soft and fluffy state, which facilitates initial wrapping and adaptation to different body shapes. When the cooling treatment begins, cold water is introduced into the water bladder layer 4 and maintained at a low temperature (e.g., 5-15℃). The low temperature is conducted through the inner film layer 51, causing the gas in the cavity to condense into liquid, and the volume shrinks rapidly, resulting in a negative pressure inside the cavity. The external atmospheric pressure tightly flattens the outer protective layer 5. At this time, the grid structure in the middle ensures that the upper and lower films will not completely collapse and stick together when under pressure, but instead form dense micro-support points. This makes the flattened outer protective layer 5 exhibit extremely high in-plane stiffness and bending strength. Together with the internal rigid skeleton layer 3, they form a sturdy "low-temperature exoskeleton," which greatly enhances the structural stability and fixation effect of the flexible cooling plate in the working state.

[0068] In some embodiments, in order to facilitate the replacement and cleaning of the inner contact layer 2, a first magnetic element 43 can be provided on the side edge of the water bladder layer 4 near the inner contact layer 2, and a second magnetic element 21 can be provided on the corresponding edge edge of the inner contact layer 2, so that the two can be reliably connected and quickly disassembled through magnetic attraction.

[0069] In some embodiments, to optimize thermal management, the inner thin film layer 51 of the outer protective layer 5 is preferably made of a high thermal conductivity material to accelerate the condensation of the medium inside the cavity; while the outer thin film layer 52 is made of a thermal insulation material to reduce the loss of cold energy to the environment, improve energy efficiency and prevent condensation on the surface of surrounding objects.

[0070] In some embodiments, to optimize the water flow distribution and heat exchange efficiency within the water bladder layer 4, a partition rib 44 can be provided in the middle of the interior of the water bladder layer 4 to divide the internal space into an inflow cavity 45 and an outflow cavity 46 on both sides. The partition rib 44 is provided with a guide port connecting the two cavities, forming a U-shaped or serpentine unidirectional water flow path.

[0071] In some embodiments, a plurality of staggered flow-blocking ribs 47 can be provided in both the inflow cavity 45 and the outflow cavity 46 to disturb the water flow, break the laminar boundary layer, promote sufficient heat exchange between the fluid and the bladder wall, and ensure the uniformity of the cold compress temperature. The water bladder layer 4 is provided with an inlet pipe 48 and an outlet pipe 49, which are respectively connected to the inflow cavity 45 and the outflow cavity 46, and then connected to the circulation pipeline 11 of the main unit.

[0072] In summary, this traditional Chinese medicine orthopedic splint has the following characteristics:

[0073] 1. A collaborative working mechanism of "triple intelligent response" has been realized: the device is not a passive container, but an intelligent system that can actively change its physical properties according to temperature;

[0074] (1) Stiffness response of skeleton layer 3: Based on the phase change characteristics of shape memory polymer, it realizes "hard support at low temperature and soft fit at high temperature", which is the core of adaptive fixation, taking into account both stable fixation during treatment and comfortable fit during the interval.

[0075] (2) Volume / density response of outer protective layer 5: Through the controllable gas-liquid phase change of the internal medium, "tight wrapping at low temperature and loose expansion at high temperature" is achieved, which, together with the skeleton layer 3, forms a high-rigidity protective structure when cold-applied.

[0076] (3) Fluid management response of inner contact layer 2: Through the combination of micro-grooves and hydrophilic materials, condensate is actively guided, which completely solves the problem of skin immersion during the cold compress process and improves safety and comfort.

[0077] 2. Innovatively solves the problem of condensate management: The "active flow guidance" design of the inner contact layer 2 transforms the traditional "blocking" approach into "dredging", greatly eliminating the adverse effects of condensate and significantly improving the user experience.

[0078] 3. A highly efficient system architecture combining active and passive loops was constructed:

[0079] Active circulation system: Composed of the main unit and water sac layer 4, it provides continuous, controllable, and temperature-uniform precise cryotherapy, ensuring the treatment effect.

[0080] Passive adaptive system: Composed of skeleton layer 3 and outer protective layer 5, it does not require external energy drive and can intelligently adjust the stiffness, shape and wrapping of the overall structure by relying solely on natural temperature changes before and after treatment, thus achieving adaptive optimization of fixation effect.

[0081] 4. Modular and humanized design: The flexible cold compress has a multi-layer structure that can be disassembled and cleaned (such as the inner contact layer 2). The connectors are easy to wear. The overall design fully considers the convenience of clinical use, hygiene requirements and long-term patient comfort.
