Abstract
Description
Technical Field
[0001] This invention relates to the field of cold compress technology for burns, specifically a cold compress device for burns. Background Technology
[0002] After a burn, residual heat will continue to spread and worsen the injury. Applying cold compresses can quickly absorb heat and prevent it from penetrating, thereby relieving vasodilation and spasms to reduce swelling, reducing nerve sensitivity to relieve pain, and also reducing the area of tissue necrosis to reduce the risk of infection, thus reducing the harm of burns.
[0003] Once the sustained damage from heat is stopped, the excessive dilation and spasm of local blood vessels caused by high temperatures are relieved. Vasoconstriction reduces the leakage of blood and tissue fluid into the injured area, thereby reducing swelling. At the same time, low temperatures reduce the sensitivity of nerve endings, decreasing the transmission of pain signals and significantly alleviating pain. Furthermore, as the extent of damage is controlled, the area of local tissue necrosis shrinks. Necrotic tissue is a breeding ground for bacteria, thus reducing the risk of subsequent infection and creating favorable conditions for normal wound healing.
[0004] Circulating cold compress devices are commonly found in hospital physiotherapy or burn departments. They are electronic devices that use circulating cooling water or semiconductor cooling to precisely control temperature and cold compress time, and are used for patients with large areas or those requiring long-term cold compresses. However, during use, the cold compress fixation band remains static and tightly attached to the wound, ignoring the dynamic physiological needs of the body's tissues during treatment. Because the fixation band cannot dynamically adjust pressure or periodically loosen, the fragile new tissue or burn wound is subjected to continuous mechanical pressure. This not only hinders local capillary blood circulation and tissue fluid drainage, increasing the risk of pressure sores and infection, but also exacerbates patient discomfort and reduces treatment tolerance due to prolonged continuous low-temperature contact.

Therefore, the invention is not limited to the specific embodiments disclosed below.
[0032] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention.

[0033] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.
[0034] Example 1, referring to Figure 1 - Figure 7 This is the first embodiment of the present invention, which provides a burn cold compress device. The device includes an infusion base 101 and further includes: The conductive structure 200 includes a cold compress shell 201 fixedly connected to the surface of the infusion base 101, a lower sealing plate 202 fixedly connected to the bottom of the cold compress shell 201, an upper sealing plate 203 fixedly connected to the top of the cold compress shell 201, several linearly arranged fluid columns 204 fixedly connected to the surface of the cold compress shell 201, an adjustment component 205 fixedly connected to the surface of the fluid columns 204, and a conductive component 206 rotatably connected to the surface of the adjustment component 205. The cold compress shell 201 provides a stable installation base, and the lower sealing plate 202 and the upper sealing plate 203 seal against leakage of the condensate medium. The condensate medium is generally circulating condensate water. The working principle of this part is existing technology and is clearly understood by those skilled in the art, so it will not be described in detail here. The linear arrangement of the fluid columns 204 ensures uniform cold compress, and the adjustment and conductive component 206 provides a foundation for dynamic adjustment, avoiding static pressure on the wound.
[0035] The extension structure 300 includes a linkage layer 301 fixedly connected to the surface of the adjustment component 205, a cooling pad 302 fixedly connected to the surface of the linkage layer 301, several ventilation holes 303 formed on the surface of the cooling pad 302, a fixing strip 304 fixedly connected to the surface of the cooling pad 302, and an extension component 305 fixedly connected to the surface of the fixing strip 304. The linkage layer 301 transmits motion to enable the cooling pad 302 to dynamically contact the wound. The cooling pad 302 is soft and improves comfort. The ventilation holes 303 enhance breathability and prevent infection. The fixing strip 304 prevents displacement. The extension component 305 helps to adapt to the burn area and intermittently wrap the cooling pad 302 with cold compresses at the same frequency.
[0036] The adjusting assembly 205 includes a connecting ring 2051 fixedly connected to the surface of the liquid column 204, a plurality of first anti-detachment pads 2052 fixedly connected to the surface of the connecting ring 2051 and arranged circumferentially, a spring 2053 fixedly connected to the surface of the first anti-detachment pads 2052, and a second anti-detachment pad 2054 fixedly connected to one end of the spring 2053. The connecting ring 2051 ensures a stable connection between the adjusting assembly 205 and the liquid column 204, the first anti-detachment pads 2052 limit the spring 2053 to prevent displacement, the spring 2053 provides extension and retraction reset power, and the second anti-detachment pad 2054 ensures smooth operation of the assembly.
[0037] The adjustment component 205 also includes a squeezing cylinder 2055 slidably connected to the surface of the liquid-conducting column 204, and an inner conical ring 2056 fixedly connected to the surface of the liquid-conducting column 204 and located on the side of the squeezing cylinder 2055. The squeezing cylinder 2055 is fixedly connected to the surface of the second anti-detachment pad 2054. The surface of the cold compress shell 201 is fixedly connected with a fleece strip 207 and a bristle strip 208. The fleece strip 207 and the bristle strip 208 can be bonded together to achieve quick fixation of the cold compress device to the skin or clothing around the patient's burn site without relying on additional straps, simplifying the device wearing operation. At the same time, the bonding strength can be manually adjusted, making it convenient to disassemble and adjust the position at any time according to the patient's comfort or treatment needs.
[0038] The sliding extrusion cylinder 2055 can intermittently block the drain hole 2057 to control the rhythm of condensate discharge. The inner conical ring 2056 guides the flow of the medium and triggers subsequent actions. The extrusion cylinder 2055 is fixed to the second anti-detachment pad 2054 to ensure coordinated action of the components. The inner conical ring 2056 guides the flow direction of the condensate and can also drive the subsequent conduction component 206 to move in coordination with the flow of the condensate, providing triggering conditions for the entire dynamic adjustment process.
[0039] The infusion base 101 has a supply and return hose 102 fixedly connected to its surface. A connecting base 103 is fixedly connected to the surface of the supply and return hose 102. An infusion tube 401 is fixedly connected to the surface of the connecting base 103. An inlet / outlet water connector 402 is fixedly connected to the surface of the inlet / outlet water connector 402. A cooling compress box 403 is fixedly connected to the surface of the cooling compress box 403. A movable base 404 is fixedly connected to the surface of the cooling compress box 403. The cooling medium prepared by the cooling compress box 403 is output through the inlet / outlet water connector 402, transported to the supply and return hose 102 through the infusion tube 401 and connecting base 103, and finally guided by the infusion base 101 into the circulation channel inside the cooling compress shell 201. After heat exchange, the medium returns to the cooling compress box 403 along the original path for cooling, forming a closed-loop circulating cooling compress system. The movable base 404 provides stable support and convenient mobility for the entire system. The working principle of this part is existing technology, which is clearly understood by those skilled in the art and will not be elaborated here.
[0040] During use, the cooling machine housing 403 serves as a cold source preparation device. First, the cooled condensed medium is output through the inlet / outlet water connector 402, which is fixedly connected to the surface. Then, the condensed medium flows along the infusion pipe 401, which is fixedly connected to the inlet / outlet water connector 402. The infusion pipe 401 is securely connected to the supply / return hose 102 through the connecting base 103. Finally, the condensed medium is transported to the infusion base 101 through the supply / return hose 102. The infusion base 101 accurately guides the condensed medium into the preset circulation channel inside the cooling housing 201, which is fixedly connected to it. The working principle of this part is existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.
[0041] When the condensing medium enters the liquid-conducting column 204 along the infusion base 101 and the cooling shell 201 and flows, the inner conical ring 2056 fixedly connected to the surface of the liquid-conducting column 204 guides the flow direction of the medium, so that the medium forms a specific flow trajectory. This not only optimizes the flow efficiency of the medium, but also triggers subsequent dynamic adjustment actions. At the same time, the squeezing cylinder 2055 slidably connected to the surface of the liquid-conducting column 204 slides under the action of the spring 2053 in the medium flow pressure and adjustment component 205. The squeezing cylinder 2055 is fixedly connected to the second anti-detachment pad 2054 fixedly connected to one end of the spring 2053. The other end of the spring 2053 is fixed to the connecting ring 2051 on the surface of the liquid-conducting column 204 through the first anti-detachment pad 2052. The first anti-detachment pad 2052 and the second anti-detachment pad 2054 work together to prevent the spring 2053 from shifting during the extension and retraction process, ensuring that the extension and retraction reset power provided by the spring 2053 can be stably transmitted.
[0042] The sliding of the squeezing cylinder 2055 intermittently blocks the pre-set drainage hole 2057 on the surface of the liquid column 204. By controlling the opening and closing rhythm of the drainage hole 2057, the flow rate and speed of the condensing medium discharged from the liquid column 204 are adjusted. This dynamic adjustment mechanism avoids the problem of wound pressure caused by the continuous static discharge of the medium in traditional cold compress devices. It not only ensures effective heat exchange between the condensing medium and the wound, but also reduces the adverse effects of static pressure on wound healing.
[0043] The condensed medium discharged from the liquid column 204 then enters the linkage layer 301, which is fixedly connected to the adjustment component 205. The linkage layer 301 can transmit the flow or pressure change of the condensed medium to the cooling pad 302. The cooling pad 302 is made of soft material, which can conform to the shape of the burn wound when in contact with it, improving wearing comfort. At the same time, several ventilation holes 303 on the surface of the cooling pad enhance breathability, effectively reducing the moist environment of the wound and reducing the risk of infection. The fixing strip 304 fixedly connected to the surface of the cooling pad 302 further prevents the device from shifting during use.
[0044] Finally, the condensate, whose temperature has risen after heat exchange, flows in the reverse direction along the original transmission path, passing sequentially through the infusion base 101, the supply and return hose 102, the connecting base 103, the infusion pipe 401, and the inlet and outlet water connectors 402 back to the cooling box 403. After being cooled again in the box, it is recycled again, forming a closed condensate circulation system. The working principle of this part is existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.
[0045] Example 2, refer to Figure 1 - Figure 8 This is the second embodiment of the present invention, which differs from the first embodiment in that: the inner conical ring 2056 has an upper opening and a lower opening distributed along the axial direction. The diameter of the upper opening of the inner conical ring 2056 is larger than the diameter of the lower opening. The inner edges of the upper and lower openings enclose each other to form an internal inclined surface of the inner conical ring 2056. The design of the upper opening diameter being larger than the lower opening diameter of the inner conical ring 2056 increases the flow force of the condensing medium as the channel narrows, providing sufficient power for the subsequent operation of the conduction component 206 without the need for additional power components. The internal inclined surface guides the smooth flow of the condensing medium, avoiding local accumulation caused by medium stagnation within the ring, ensuring medium transmission efficiency, and thus ensuring the stable start of the dynamic adjustment function, laying a power foundation for solving the problem of static pressure wounds.
[0046] Compared to Embodiment 1, the inner conical ring 2056 further includes multiple drainage holes 2057 on its internal inclined surface. These drainage holes 2057 are arranged circumferentially along the surface of the inner conical ring 2056, each penetrating the ring wall radially and extending to the outer surface of the liquid-conducting column 204. Each drainage hole 2057 is located between two adjacent springs 2053. The circumferential arrangement of the drainage holes 2057 ensures uniform discharge of the medium, guaranteeing even cooling. The unobstructed path of the drainage holes 2057 penetrating the ring wall to the liquid-conducting column 204, and their location between adjacent springs 2053, prevents obstruction and compression by the springs 2053, ensuring coordinated function between drainage and the springs 2053.
[0047] Furthermore, the transmission assembly 206 includes two positioning bases 2061 rotatably connected to the surface of the extrusion cylinder 2055, a transmission rod 2062 fixedly connected between the two positioning bases 2061, and two fixing plates 2063 fixedly connected to the surface of the transmission rod 2062 and symmetrically positioned. The two positioning bases 2061 provide a stable rotational foundation for the transmission rod 2062, which can drive the fixing plates 2063 to move synchronously. The symmetrically arranged fixing plates 2063 can evenly receive power and transmit it to subsequent components, ensuring the overall stability of the transmission assembly 206 and providing a reliable power transmission path for the dynamic adjustment and breathing fit of the device.
[0048] Furthermore, the transmission assembly 206 also includes circumferentially arranged curved fan blades 2064 fixedly connected to the surface of the fixed plate 2063, and an eccentric block 2065 fixedly connected to the surface of the transmission rod 2062 and located directly below the liquid column 204. One end of the curved fan blades 2064 is fixedly connected to the edge of the fixed plate 2063, and the other end is fixedly connected to the side of the transmission rod 2062. The other end of the curved fan blades 2064 does not contact the transmission rod 2062. The circumferentially arranged curved fan blades 2064 on the surface of the fixed plate 2063 can more effectively bear the impact force of the condensing medium flowing through the inner cone ring 2056, drive the transmission rod 2062 to rotate, improve the power transmission efficiency, and ensure the stable operation of the subsequent eccentric block 2065.
[0049] The eccentric block 2065, located directly below the liquid column 204 on the surface of the transmission rod 2062, can strike the bottom of the liquid column 204 under the drive of the transmission rod 2062, causing the liquid column 204 to extend and retract at the same frequency. This provides a direct triggering force for the breathing-like relative movement between the extrusion cylinder 2055 and the liquid column 204, thereby achieving dynamic contact between the cooling pad 302 and the cooling medium. When the condensing medium flows through the inner conical ring 2056, the upper opening of the inner conical ring 2056 is larger than the lower opening, generating an impact force that drives the curved fan blade 2064 to rotate smoothly. The fan blade drives the transmission rod 2062 to rotate. The eccentric block 2065 on the transmission rod 2062 regularly strikes the bottom of the fluid-conducting column 204, providing a direct triggering force for the movement of the fluid-conducting column 204. After being struck, the fluid-conducting column 204 reciprocates along the compression cylinder 2055 under the extension and retraction reset action of the spring 2053 in the adjustment component 205, thereby forming a breathing-like relative movement between the compression cylinder 2055 and the fluid-conducting column 204. This relative movement is synchronously transmitted to the cold compress pad 302 through the linkage layer 301, ultimately achieving dynamic contact between the cold compress pad 302 and the wound, effectively avoiding static pressure on the wound.
[0050] One end of the curved fan blade 2064 is fixed to the fixing plate 2063, and the other end is fixed to the side of the transmission rod 2062 without contacting the transmission rod 2062. During rotation, one end of the curved fan blade 2064 is stably supported by the fixing plate 2063, while the other end is fixed to the side of the transmission rod 2062 without touching the main body. This ensures power connection without hindering rotation, allowing the curved fan blade 2064 to flexibly withstand the impact of the medium and rotate smoothly, reducing jamming and improving power transmission efficiency. During drainage by the extrusion cylinder 2055, the curved fan blade 2064 rotates flexibly and stably, driving the transmission rod 2062 to cause the eccentric block 2065 to strike regularly. By opening the liquid column 204, the liquid column 204 and the squeezing cylinder 2055 move in a stable, breathing manner, thereby causing the squeezing cylinder 2055 to regularly block the drainage hole 2057, avoiding drainage disorder, ensuring uniform and stable drainage, and providing a continuous medium for dynamic cold compresses; reducing the impact of water on the rotation of the eccentric block 2065, the curved fan blade 2064 does not touch the main body of the transmission rod 2062, reducing the direct impact of water flow on the transmission rod 2062 and the eccentric block 2065 during rotation, and the curved structure guides the flow, avoiding disorderly water flow interference with the eccentric block 2065, ensuring its stable rotation, ensuring the operation of the dynamic adjustment system, and relieving static pressure on the wound.
[0051] The remaining structure is the same as that in Example 1.
[0052] Example 3, referring to Figure 1 - Figure 11This is the third embodiment of the present invention, which differs from the second embodiment in that: the extension component 305 includes a plurality of inner connecting blocks 3051 fixedly connected to the surface of the linkage layer 301, an elastic strip 3056 fixedly connected to the surface of the inner connecting blocks 3051, an outer connecting block 3054 fixedly connected to the surface of the elastic strip 3056, and a positioning block 3055 fixedly connected to the surface of the elastic strip 3056. The inner connecting blocks 3051 stabilize the elastic strip 3056 and the linkage layer 301, ensuring synchronous transmission of movements. The deformation of the elastic strip 3056 provides a margin for expansion and contraction, avoiding rigid pressure on the wound surface. The outer connecting blocks 3054 connect the elastic strip 3056 and the cold compress shell 201, optimizing the fit of the cold compress pad 302. The positioning blocks 3055 limit the deformation of the elastic strip 3056, ensuring the stable operation of the extension component 305 and maintaining the dynamic cold compress effect.
[0053] Compared to Embodiment 2, the elastic strip 3056 further includes a valley 3052 and a peak 3053. An inner connecting block 3051 is fixedly connected to the surface of the valley 3052, and an outer connecting block 3054 is fixedly connected to the surface of the peak 3053. The outer connecting block 3054 is fixedly connected to the surface of the cold compress shell 201. One end of the positioning block 3055 is fixedly connected to the fixed soft strip 304, and the other end of the positioning block 3055 is fixedly connected to the cold compress shell 201.
[0054] The inner connecting block 3051 is connected to the valley 3052, and the outer connecting block 3054 is connected to the peak 3053, so that the deformation of the elastic strip 3056 is evenly transmitted and the connection is strengthened. The outer connecting block 3054 is fixed to the cold compress shell 201 to ensure that the expansion action and overall adjustment are coordinated. The positioning block 3055 is connected to the fixed soft strip 304 and the cold compress shell 201 at both ends, preventing the cold compress soft pad 302 from shifting, limiting the deformation of the elastic strip 3056, improving the adaptability of the wound, reducing friction and pressure, and taking into account both stability and comfort.
[0055] The wavy elastic strip 3056 is a continuous strip that spirals circumferentially inside the cooling cover 201. At room temperature, the elastic strip 3056 exhibits a relaxed wavy shape, maintaining maximum spacing between adjacent crests and troughs. The crests and outer connecting blocks 3054 abut against the cooling cover 201, while the troughs and inner connecting blocks 3051 closely adhere to the integrated structure of the linkage layer 301 and the padding. Therefore, the cooling cover 201 and the linkage layer 301 are in a relaxed state, exerting almost no pressure on the limb. The wavy elastic strip 3056 has the characteristic of shortening at low temperatures and returning to its original length when the temperature rises.
[0056] When the low-temperature condensing medium delivered by the cold compress machine housing 403 enters the cold compress shell 201, it enters a sealed space between the cold compress shell 201 and the linkage layer 301 through the drain hole 2057. According to existing technology, heat exchange occurs. Due to the low-temperature environment, the corrugated elastic strip 3056 contracts. The inner connecting block 3051, fixedly connected at the valley 3052, moves towards the cold compress shell 201 as the elastic strip 3056 contracts, causing the linkage layer 301 to move synchronously. The linkage layer 301 further transmits the action, causing the cold compress pad 302 to adhere to the wound surface. The outer connecting block 3054, fixedly connected at the peak 3053 of the elastic strip 3056, presses more tightly against the cold compress shell 201 due to the contraction of the elastic strip 3056, optimizing the contact stability between the cold compress pad 302 and the wound surface. Simultaneously, the positioning block 3055 is fixed at both ends to the fixing strip 304 and the cold compress shell 201, respectively, preventing… During use, the cooling pad 302 shifts position, but the deformation of the elastic strip 3056 is limited to ensure the continuity of the action. When the temperature of the condensing medium rises, the wavy elastic strip 3056 returns to its relaxed wavy shape at room temperature, and the distance between the valleys 3052 and the peaks 3053 increases, causing the inner connecting block 3051 to move outward. The linkage layer 301 transmits the reverse action, causing the cooling pad 302 to relax, forming a periodic breathing dynamic expansion and contraction, avoiding continuous pressure on the wound from rigid components. The deformation margin of the elastic strip 3056 adapts to burn wounds of different shapes or locations. At the same time, the spiral winding method of the wavy structure enhances the uniformity of the expansion action. Combined with the limiting effect of the positioning block 3055, the cooling pad 302 is stably attached while improving the comfort of wound contact, reducing the risk of friction and pressure, and ultimately achieving the technical effect of dynamic expansion and flexible cooling.
