Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to a heat dissipation bracket for medical devices. Background Technology

[0002] In the medical field, medical devices operate in complex and variable environments. During physiological activities, contact with external machinery, and transportation and storage, they are inevitably subjected to external forces. These forces can not only cause deformation and displacement of the medical device stent, affecting its support and fixation effectiveness, but also impact internal components and exacerbate heat generation. The stable operation of medical devices is crucial for treatment outcomes and patient safety. Existing medical device stents often employ simple support and fixation structures with limited functionality, making it difficult to meet the complex demands of practical applications. This is especially true for medical devices with heat dissipation capabilities, where the effectiveness of heat dissipation directly affects device performance and lifespan.

[0003] However, existing medical device heat dissipation supports have the following shortcomings in practical use: Currently available medical device heat dissipation supports typically have multiple heat dissipation fins to enhance heat dissipation capacity, but these fins are all stationary. During the operation of the medical device, heat is transferred to the heat dissipation fins through conduction. Because the fins are stationary, airflow between the fins relies solely on natural airflow, which is slow and unstable. This makes it difficult for heat to be quickly and effectively dissipated into the surrounding environment, causing a large amount of heat to concentrate on the heat dissipation fins, resulting in localized overheating of the support. Therefore, this application proposes a medical device heat dissipation support. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a medical device heat dissipation bracket that can increase airflow on the heat dissipation fins, improve the heat dissipation effect of the heat dissipation fins, and thus improve the operational stability of medical devices.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A heat dissipation bracket for a medical device includes a frame with a plurality of spaced-apart heat dissipation fins, wherein a groove is formed between any two of the heat dissipation fins, and further includes:

[0007] A cavity block, wherein the cavity block is disposed on the frame, and an air chamber is formed within the cavity block, and each of the partitions communicates with the air chamber; and

[0008] A heat dissipation assembly includes a compression pipe, a push rod, and a protective plate. The compression pipe is disposed on the cavity block and has a sliding chamber inside, which communicates with the air chamber. The push rod is slidably disposed on the frame, with one end of the push rod located inside the sliding chamber to seal the air chamber. The protective plate is disposed on the end of the push rod away from the compression pipe. When the protective plate is pushed by an external force, the push rod compresses the gas in the sliding chamber into the air chamber, thereby causing the gas in the air chamber to be sprayed into each of the partitions.

[0009] Optionally, the push rod includes a rod body and a top block, the top block is disposed on the rod body, the rod body slides on the frame, and the top block is adapted to slide within the sliding cavity.

[0010] Optionally, a sealing groove is provided on the top block.

[0011] Optionally, the heat dissipation assembly further includes a sealing ring, which is fitted inside a sealing groove.

[0012] Optionally, the heat dissipation assembly further includes an elastic element, and the push rod further includes a retaining ring. The retaining ring is disposed on the rod body, and the elastic element is sleeved on the rod body, with the elastic element abutting against the retaining ring and the frame body respectively.

[0013] Optionally, the heat dissipation assembly further includes a one-way rubber ring, which is disposed on the compression tube and located in the sliding cavity.

[0014] Optionally, the heat dissipation assembly further includes a guide tube disposed on the cavity block, and a guide post is disposed on the protective plate, which slides within the guide tube.

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] This utility model relates to a medical device heat dissipation support. A protective plate pushes a push rod, causing a top block on the push rod to compress gas from the sliding chamber into the air chamber, which then sprays the gas from the opening into each slot. Simultaneously, an elastic element pushes the push rod to draw gas from the air chamber, causing gas from each slot to be drawn into the air chamber. When the protective plate is subjected to external force, the gas in the air chamber can reciprocate, spraying gas into and drawing gas from each slot. This increases the flow of gas within each slot, rapidly dissipating heat concentrated on the heat dissipation fins to the surrounding environment. This prevents excessive heat accumulation on the heat dissipation fins, which could lead to localized overheating of the support, thereby improving the heat dissipation effect of the heat dissipation fins and enhancing the stability of the medical device's operation.

[0028] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0029] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings.

Therefore, they should not be construed as limitations on this utility model.

[0030] 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 as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0032] like Figures 1 to 4 As shown, in one embodiment, a medical device heat dissipation bracket 1 includes a frame 20 with a plurality of spaced heat dissipation fins 10, with a groove 11 formed between any two heat dissipation fins 10. It also includes a cavity block 30 and a heat dissipation assembly. The cavity block 30 is mounted on the frame 20, and an air chamber 31 is formed within the cavity block 30. Each groove 11 communicates with the air chamber 31. The heat dissipation assembly includes a compression pipe 40, a push rod 41, and a protective plate 42. The compression pipe 40 is mounted on the cavity block 30. A sliding chamber 400 is provided inside the compression pipe 40, and the sliding chamber 400 is connected to the air chamber 31. The push rod 41 is slidably mounted on the frame 20, and one end of the push rod 41 is located inside the sliding chamber 400 to seal the air chamber 31. The guard plate 42 is provided on the end of the push rod 41 away from the compression pipe 40. When the guard plate 42 is pushed by an external force, the push rod 41 compresses the gas in the sliding chamber 400 into the air chamber 31, thereby causing the gas in the air chamber 31 to flow into each partition 11.

[0033] It should be noted that a plurality of heat dissipation fins 10 are provided on one side of the frame 20, and the heat dissipation fins 10 are spaced apart so that there is a groove 11 between each heat dissipation fin 10, and all grooves 11 are arranged in the same direction. Furthermore, an opening 32 is provided on one side of the cavity block 30, so that the air chamber 31 inside the cavity block 30 can communicate with the external environment. Furthermore, the opening 32 extends from one end of one side of the cavity block 30 to the other end, so that when the cavity block 30 is placed on the frame 20, the opening 32 can span the ends of each groove 11, so that each groove 11 can communicate with the air chamber 31. Furthermore, a sliding chamber 400 is provided inside the compression pipe 40, the sliding chamber 400 connects the two ends of the compression pipe 40, and the sliding chamber 400 has a circular hole structure. One end of the compression pipe 40 is disposed on the cavity block 30, so that one end of the sliding chamber 400 communicates with the air chamber 31. Push rod 41 is slidably mounted on frame 20, with one end of push rod 41 extending into compression tube 40 from the end away from cavity block 30, so that one end of push rod 41 extends into sliding chamber 400 to seal air chamber 31. It should be noted that the sliding direction of push rod 41 is the same as the axial direction of sliding chamber 400, and they are coaxially arranged, so that push rod 41 can slide coaxially towards or away from compression tube 40, thereby allowing one end of push rod 41 to slide back and forth within sliding chamber 400 relative to compression tube 40. Furthermore, the protective plate 42 is positioned on the end of the push rod 41 furthest from the compression tube 40. Thus, when the protective plate 42 is subjected to external pressure, it pushes the push rod 41 closer to the compression tube 40. This causes the end of the push rod 41 located within the sliding chamber 400 to compress a portion of the gas near the cavity block 30 into the air chamber 31. Consequently, the gas in the air chamber 31 is ejected from the opening 32 into each slot 11, thereby driving the airflow on each heat dissipation fin 10. This accelerates the dissipation of heat concentrated on each heat dissipation fin 10 to the surrounding environment, thus reducing the concentration of heat on the heat dissipation fins 10 and preventing excessively high local temperatures on the support, thereby improving the stability of the medical device's operation.

[0034] like Figure 1 , Figures 3 to 4 , Figure 7 As shown, in one embodiment, the push rod 41 includes a rod body 410 and a top block 411. The top block 411 is disposed on the rod body 410, the rod body 410 slides on the frame 20, and the top block 411 slides adaptably in the sliding chamber 400.

[0035] It should be noted that the frame 20 is provided with at least two upright blocks 21, and there is a gap between the two upright blocks 21. The rod 410 passes through the two upright blocks 21, so that the rod 410 can slide relative to the frame 20. Further, a top block 411 is provided on the end of the rod 410 near the compression tube 40, and the top block 411 is located inside the sliding chamber 400. The guard plate 42 is provided on the end of the rod 410 away from the top block 411. Thus, when the rod 410 slides relative to the frame 20, the top block 411 slides coaxially within the sliding chamber 400. Further, the diameter of the top block 411 is smaller than the inner diameter of the sliding chamber 400, and the diameter of the top block 411 is close to the diameter of the sliding chamber 400, so that the top block 411 can slide appropriately within the sliding chamber 400.

[0036] like Figures 4 to 5 , Figure 8 As shown, in one embodiment, a sealing groove 4110 is provided on the top block 411. The heat dissipation assembly also includes a sealing ring 43, which is fitted inside the sealing groove 4110.

[0037] It should be noted that a sealing groove 4110 is provided in the circumferential direction of the top block 411. The sealing ring 43 is fitted inside the sealing groove 4110. Since the sliding chamber 400 is connected to the air chamber 31, the top block 411 can seal the air chamber 31. Furthermore, when the rod 410 drives the top block 411 to slide relative to the compression tube 40 and approach the chamber block 30, the gas in the sliding chamber 400 located on the side of the top block 411 and the chamber block 30 will be squeezed into the air chamber 31 by the top block 411, thereby increasing the gas capacity in the air chamber 31. Since there is also gas in the air chamber 31, when the gas in the sliding chamber 400 is squeezed into the air chamber 31, the gas is sprayed from the opening 32 on the chamber block 30 into each slot 11. Furthermore, when the rod 410 drives the top block 411 to slide away from the cavity block 30 relative to the compression tube 40, the volume of the sliding cavity 400 between the top block 411 and the cavity block 30 gradually increases, thereby drawing the gas in the air chamber 31 to the sliding cavity 400, and causing the gas in each slot 11 to flow into the air chamber 31 from the opening 32. Under the repeated pushing of the protective plate 42 by external force, the gas in the air chamber 31 is repeatedly sprayed from the opening 32 into each slot 11 and drawn into each slot 11, thereby forming a reciprocating gas flow in each slot 11. In this way, the large amount of heat concentrated on the heat dissipation fins 10 can be quickly dissipated to the surrounding environment under the reciprocating gas flow, so as to avoid the large amount of heat concentration and the formation of excessively high local temperature of the support, thereby affecting the stability of the medical device operation.

[0038] like Figure 1 , Figures 3 to 4As shown, in one embodiment, the heat dissipation assembly further includes an elastic element 44, and the push rod 41 further includes a retaining ring 412. The retaining ring 412 is disposed on the rod body 410, and the elastic element 44 is sleeved on the rod body 410. The elastic element 44 abuts against the retaining ring 412 and the frame 20 respectively.

[0039] It should be noted that the retaining ring 412 is disposed on the rod body 410 and is located between the two upright blocks 21. The elastic element 44 is a spring structure, which is sleeved on the rod body 410 and is located between the retaining ring 412 and the upright block 21 near the compression tube 40. This allows the elastic element 44 to push the retaining ring 412 to drive the rod body 410 to slide away from the compression tube 40. In turn, the rod body 410 drives the top block 411 to slide away from the cavity block 30 relative to the sliding chamber 400, thereby drawing the gas in the air chamber 31 to flow to the sliding chamber 400, and thus causing the gas in each slot 11 to flow.

[0040] like Figures 4 to 5 , Figure 8 As shown, in one embodiment, the heat dissipation assembly further includes a one-way rubber ring 45, which is disposed on the compression tube 40 and located inside the sliding chamber 400.

[0041] It should be noted that the unidirectional rubber ring 45 is composed of multiple rubber sheets 450 with arc-shaped petal structures spliced ​​together, forming a funnel-like shape after splicing. Specifically, the rubber sheets 450 are elastic rubber structures, with one end of each rubber sheet 450 connected to form a circle. Due to the curvature of the rubber sheets 450, the other ends of each rubber sheet 450 are all close to the axis in one direction, thus forming a funnel-like structure. For ease of description, the end where each rubber sheet 450 is spliced ​​together is defined as the wide mouth block, and the end where each rubber sheet 450 is close to each other is defined as the pointed end. The diameter of the pointed end when they are close to each other is smaller than the diameter of the wide mouth end. Furthermore, the wide mouth end of the unidirectional rubber ring 45 is located on the end of the compression tube 40 near the cavity block 30, and the pointed end of the unidirectional rubber ring 45 faces the sliding cavity 400. When the rod 410 rapidly pushes the top block 411 closer to the cavity block 30, the air pressure inside the sliding chamber 400 increases instantaneously. This causes the gas to flow rapidly towards the air chamber 31, compressing the inner arc surface of the one-way rubber ring 45 to bring the rubber sheets 450 closer together. These rubber sheets 450 then form a small-diameter through-hole, allowing the gas inside the sliding chamber 400 to flow slowly towards the air chamber 31, while simultaneously causing the top block 411 to slowly approach the cavity block 30. Thus, when the protective plate 42 experiences excessive external force, the top block 411 can slowly approach the cavity block 30 to release the excessive force on the protective plate 42, thereby providing a buffering effect.

[0042] It should be noted that when the rod 410 drives the top block 411 to slide closer to the cavity block 30, it also drives the retaining ring 412 to squeeze the elastic element 44. When the top block 411 slowly releases the external force on the guard plate 42, the elastic element 44 will push the retaining ring 412 to drive the top block 411 to slide away from the cavity block 30, so as to draw the gas in the air chamber 31 into the sliding chamber 400. When the gas flows through the one-way rubber ring 45, the gas will push the outer arc surface of the one-way rubber ring 45, so that the rubber pieces 450 on the tip of the one-way rubber ring 45 move away from each other, thereby increasing the diameter of the through hole. In this way, the gas can quickly flow from the air chamber 31 into the sliding chamber 400, and the top block 411 can quickly move away from the cavity block 30, allowing the guard plate 42 to quickly return to its initial state.

[0043] like Figure 1 , Figure 3 As shown, there are two cavity blocks 30 and two heat dissipation components. The two ends of each partition 11 are connected to the two cavity blocks 30 respectively, and the two heat dissipation components are connected to the two cavity blocks 30 respectively.

[0044] like Figure 1 , Figures 3 to 4 , Figure 6 As shown, in one embodiment, the heat dissipation assembly further includes a guide tube 46, which is disposed on the cavity block 30, and a guide post 47 is disposed on the protective plate 42, which slides inside the guide tube 46.

[0045] It should be noted that there are two guide tubes 46, each located on the side of the cavity block 30 away from the compression tube 40. Furthermore, there are two guard plates 42, with two guide posts 47 each located on one end of the guard plate 42, and the other ends of the guard plates 42 respectively connected to the ends of the two rods 410 away from the top block 411. Further, a pusher, also a spring structure, is slidably installed inside each of the two guide tubes 46, abutting against the inner bottom wall of the pushing guide tube 46 and the guide post 47. This allows the two guard plates 42 to slide out or retract relative to the frame 20.

[0046] like Figures 3 to 4 As shown, in one embodiment, a cushioning pad is provided on the protective plate.

[0047] It should be noted that a buffer pad 420, made of rubber, is provided on the side of the guard plate 42 closest to the push rod 41. When the guard plate 42 is impacted by an external force and approaches the frame 20, the guard plate 42 causes the buffer pad 42 to move closer to the frame 20, thus preventing the guard plate 42 from generating excessive stress on the frame 20 and avoiding the risk of deformation of the frame 20.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
