Description

Technical Field

[0001] This application relates to the field of cold precipitation preparation equipment technology, such as a melting water tank and a cold precipitation preparation instrument. Background Technology

[0002] With the continuous advancement of clinical transfusion medicine and biological agent research and development technologies, cryoprecipitate, as a key medical resource for treating hemophilia, surgical hemorrhage, and other conditions, has become a focus of industry attention due to its environmental stability and safety during preparation. Cryoprecipitate preparation typically requires thawing fresh frozen plasma in a low-temperature, constant-temperature environment, which places extremely high demands on the temperature control precision and anti-condensation performance of the thawing tank.

[0003] In related technologies, the melting water tank of a cold precipitation preparation instrument usually adopts an integrated large water tank structure design, or uses a thermal insulation cotton covering structure for insulation.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art: In related technologies, commonly used cryoprecipitate melting tanks have complex external structures and piping, making it difficult to ensure tight insulation coverage in every area using traditional insulation cotton padding. In this low-temperature plasma melting environment, the coldness of the internal medium is rapidly transferred to the exterior through weak insulation points, resulting in severe condensation. Condensation not only compromises the cleanliness of the preparation environment but also easily leads to mold growth or equipment corrosion, seriously affecting the safety of plasma preparation and the operational stability of the equipment.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0030] like Figures 1 to 6 As shown, this embodiment of the present disclosure provides a melting water tank and a cold precipitation preparation apparatus, which can prevent the coldness of the medium inside the melting water tank from being transferred outward, thereby avoiding condensation.

[0031] like Figures 1 to 6As shown, this embodiment of the present disclosure provides a melting tank comprising: multiple melting boxes 10, multiple water circuit components 20, a support assembly 30, and an insulation layer 40. The multiple melting boxes 10 are arranged side-by-side and are independent of each other. Each melting box 10 includes a receiving cavity 11 for accommodating plasma bags; wherein, a receiving gap 101 is provided between the side-by-side melting boxes 10; multiple water circuit components 20 are provided corresponding to the multiple melting boxes 10, each water circuit component 20 including a pipe 201 communicating with the receiving cavity 11, and the pipe 201 is at least partially disposed within the receiving gap 101; the support assembly 30 is used to assemble and fix the multiple melting boxes 10 and the water circuit components 20 into a melting device; the insulation layer 40 is formed using an integral foaming process, and the insulation layer 40 is used to cover at least a portion of the outer surface of the melting device and fill the receiving gap 101 between the multiple melting boxes 10 to isolate cold energy transfer and inhibit condensation on the outer surface.

[0032] Specifically, multiple melting boxes 10 are arranged side by side in a horizontal direction. Each melting box 10 is independent and not connected to each other. Each melting box 10 has an upward-opening receiving cavity 11. The inner size of the receiving cavity 11 is adapted to the shape of the plasma bag to accommodate the plasma bag. A receiving gap 101 is reserved between two adjacent melting boxes 10, and the gap width is uniform. Multiple water circuit components 20 are arranged one-to-one with the multiple melting boxes 10. Each water circuit component 20 includes a pipe 201. One end of the pipe 201 is connected to the receiving cavity 11 of the corresponding melting box 10, and part of the pipe 201 is arranged in the receiving gap 101 between adjacent melting boxes 10 to make full use of the gap space and achieve a compact arrangement of the pipe 201. The support assembly 30 is assembled with all the melting boxes 10 and water circuit components 20 to integrate and fix the dispersed melting boxes 10 and water circuit components 20 into an integrated melting device, so that the components form a structurally linked whole. The insulation layer 40 is formed on the outside of the melting device using an integral foaming process. The formed insulation layer 40 covers the outer surface of the melting device and completely fills the accommodating gaps 101 between the multiple melting boxes 10. In this way, the independent melting boxes 10 isolate the melting environment of each plasma bag from each other, preventing the melting medium from flowing between different melting boxes 10. The integrally foamed insulation layer 40 is in direct contact with the melting device and pipeline 201, with no additional gaps, effectively preventing the cold energy of the low-temperature medium inside the melting device from being transferred outwards. This design solves the problem of cross-contamination of plasma bags due to leakage in traditional integral melting tanks, while avoiding the defects of loose adhesion and cold energy leakage in traditional insulation cotton application methods. It achieves effective cold energy isolation, inhibits the generation of condensation on the outer surface of the melting tank, and balances the safety of plasma melting with the stability of equipment operation.

[0033] In some embodiments, the water circuit assembly 20 includes: an inlet pipe 21, a return pipe 22, and an overflow pipe 23. The inlet pipe 21 is used to deliver the melting medium to the accommodating cavity 11; the return pipe 22 is connected to the bottom of the accommodating cavity 11; and the overflow pipe 23 is connected to the upper part of the accommodating cavity 11.

[0034] Specifically, the water circuit assembly 20's pipes 201 may include an inlet pipe 21, a return pipe 22, and an overflow pipe 23. The outlet of the inlet pipe 21 is connected to the receiving cavity 11 of the melting box 10, continuously supplying the low-temperature melting medium into the receiving cavity 11 to provide a constant-temperature medium for the water bath melting of the plasma bag. The inlet of the return pipe 22 is directly connected to the bottom of the receiving cavity 11, allowing the melting medium in the receiving cavity 11 to flow back from the bottom. The inlet of the overflow pipe 23 is connected to the upper part of the receiving cavity 11, and the height of the overflow pipe 23 matches the safe liquid filling height of the receiving cavity 11. In this way, the inlet pipe 21 and the return pipe 22 cooperate to form a circulating flow path for the melting medium, ensuring a uniform temperature of the melting medium in the receiving cavity 11 and avoiding localized temperature differences that could affect the plasma melting efficiency. Meanwhile, when the melting medium in the receiving cavity 11 is overfilled, the excess medium will naturally flow out from the overflow pipe 23 in the upper part of the receiving cavity 11, thus controlling the overflow of the medium. This design solves the problem that a single pipe 201 cannot achieve melting medium circulation and is prone to overfilling and overflow. Through the coordinated arrangement of the inlet pipe 21, return pipe 22 and overflow pipe 23, a closed and controllable water circulation system is formed, which improves the melting efficiency and uniformity of the plasma bag, while avoiding problems such as water accumulation around the equipment and additional loss of cold energy caused by melting medium overflow.

[0035] In some embodiments, a sealing element is provided at the connection between the water inlet pipe 21, the water return pipe 22, the overflow pipe 23 and the melting box 10, and the connection between the pipe 201 and the melting box 10 is fixed by welding.

[0036] Specifically, the sealing element is fitted into the connecting gap between each pipe 201 and the melting box 10, and the welding point is formed on the outer periphery of the connection between each pipe 201 and the melting box 10. The welding method creates a rigid connection between the pipe 201 and the melting box 10, ensuring the structural strength of the connection and preventing the pipe 201 from loosening and falling off during long-term use. The sealing element provides a secondary seal to the connecting gap after welding, eliminating gaps and preventing the melting medium from leaking from the connection. This design solves the problem of easy leakage and cold energy leakage from the connection between the pipe 201 and the melting box 10, achieving a leak-proof seal and structural stability at the connection, preventing cold energy loss and increased condensation due to medium leakage, and simultaneously improving the connection stability and service life of the water circuit assembly 20 and the melting box 10.

[0037] In some embodiments, the melting box 10 includes a spacer support plate 12. The spacer support plate 12 is configured as a sidewall of the melting box 10 and is connected to the support assembly 30; wherein the spacer support plates 12 of adjacent melting boxes 10 are used to define a receiving gap 101 between the adjacent melting boxes 10.

[0038] Specifically, the spacer support plate 12 serves as the outer wall of the melting box 10 and is directly connected to the support assembly 30. Each melting box 10 has a spacer support plate 12 on one or both sides. The spacer support plates 12 of adjacent melting boxes 10 are arranged opposite each other, and the two opposing spacer support plates 12 together define the accommodating gap 101 between the two adjacent melting boxes 10. The width of the accommodating gap 101 is determined by the thickness and installation position of the spacer support plate 12. This arrangement allows the structure of the melting box 10 and the definition of the accommodating gap 101 to form an integrated design, avoiding the structural complexity caused by additional partition components. Furthermore, the width of the accommodating gap 101 defined by the spacer support plate 12 is uniform, without any unevenness. This solves the problems of insufficient foaming material filling caused by the lack of a dedicated partition structure in the traditional melting box 10 and the uneven gaps between adjacent melting boxes 10. It achieves standardized definition of the gap 101, ensuring that the foaming material can uniformly fill the gap in the subsequent overall foaming process, so that the insulation layer 40 is formed completely, improving the effect of cold insulation and anti-condensation. At the same time, it simplifies the structural design and strengthens the structural strength of the melting box 10 itself.

[0039] In some embodiments, the support assembly 30 includes a fixed support 31 and a foamed base plate 32. The fixed support 31 is disposed around the periphery of the melting device and is fixedly connected to the spacer support plate 12; the foamed base plate 32 is disposed at the bottom of the melting device; wherein the fixed support 31 and the foamed base plate 32 are sealed together to form a frame structure surrounding the outside of the melting device.

[0040] Specifically, the fixing bracket 31 is arranged in a frame-like manner around the periphery of the melting device to achieve circumferential positioning of all melting boxes 10. The foaming base plate 32 is horizontally arranged at the bottom of the melting device and covers the bottom area of ​​the melting device. The bottom edge of the fixing bracket 31 is sealed to the edge of the foaming base plate 32, and the two together form a frame structure that is closed on the outside and used to accommodate the melting boxes 10 and the water channel assembly 20 on the inside. The frame-like fixing bracket 31 achieves circumferential fixation of the melting device, and the foaming base plate 32 provides support for the bottom of the melting device. The sealed connection between the two forms a closed enclosure structure on the outside of the melting device, without any open gaps or openings. This arrangement solves the problem that a simple fixing structure alone cannot integrate the melting boxes 10 and the water channel assembly 20 into a stable whole and that the foaming material is prone to leakage from gaps during the foaming process. It forms an integrated closed frame structure, ensuring the overall structural stability of the melting device, preventing leakage of the foaming material during the foaming process, ensuring the molding integrity of the insulation layer 40, and providing a structural foundation for the smooth implementation of the overall foaming process.

[0041] In some embodiments, the support assembly 30 further includes a connecting plate 33. The connecting plate 33 is fixedly connected to a plurality of melting boxes 10 and to a fixed support 31, and the connection position of the connecting plate 33 to the melting box 10 is close to the opening of the melting box 10.

[0042] Specifically, the connecting plate 33 is a flat plate structure, and the connecting plate 33 has clearance notches 331 corresponding to the positions of the multiple melting boxes 10. The upper edges of the multiple melting boxes 10 pass through the multiple clearance notches 331 respectively, and are directly fixedly connected to the edges of the clearance notches 331. The outer edge of the connecting plate 33 is fixedly connected to the inner sidewall or edge of the fixing bracket 31, and the connection position of the connecting plate 33 to the melting box 10 is close to the upward opening of the melting box 10. It can be understood that the upward opening of the melting box 10 is a structurally weak area, which is prone to warping and deformation under stress. The connecting plate 33 provides lateral connection and fixation to the openings of the multiple melting boxes 10, limiting the warping deformation at the openings of the melting boxes 10, and further forming a rigid linkage between the melting boxes 10 and the fixing bracket 31, improving the flatness of the overall frame. This design solves the problem of weak structure at the opening of the melting box 10, which is prone to warping after long-term use, leading to cracking of the insulation layer 40 and leakage of cold energy. It strengthens the structural stability at the opening of the melting box 10, ensures the flatness of the overall frame of the melting device, and makes the insulation layer 40 fit seamlessly with the frame structure without cracking or falling off, thus ensuring the durability of the cold insulation and anti-condensation effect.

[0043] In some embodiments, the fixed bracket 31 is connected to the spacer support plate 12 by welding; the fixed bracket 31 is connected to the foam base plate 32 by welding; and the fixed bracket 31 is connected to the connecting patch plate 33 by welding.

[0044] Specifically, welding points are formed at the contact points between the fixed bracket 31 and the spacer support plate 12, at the edge sealing points between the fixed bracket 31 and the foam base plate 32, and at the contact points between the fixed bracket 31 and the outer edge of the connecting patch plate 33. This welding connection method allows for a seamless, rigid connection between the components of the bracket assembly 30 and the melting box 10, ensuring consistent structural strength at each connection point. This results in an indivisible, rigid frame for the melting device, capable of withstanding the molding pressure of the foaming process and vibrations from long-term use. This design solves the problems of uneven connection strength, loosening over time, and cold leakage caused by different connection methods. It achieves a fully rigid connection for the entire frame of the melting device, eliminating all structural gaps that allow cold leakage, further improving the insulation and anti-condensation effect, and ensuring the structural stability of the melting device meets the requirements of long-term, high-frequency use of medical equipment.

[0045] In some embodiments, the support assembly 30 further includes a fixing plate 34. The fixing plate 34 is fixedly connected to the foamed base plate 32 and is used to fix the melting water tank.

[0046] Specifically, the fixing plate 34 is a block or plate structure, and there can be one or more. Multiple fixing plates 34 are evenly distributed on the outer surface of the foamed base plate 32. The fixing plates 34 are directly fixed to the foamed base plate 32. The fixing plates 34 are provided with mounting holes adapted to external installation equipment for the fixed installation of the melting water tank and the external equipment. The fixing plates 34 provide an installation structure for the melting water tank. During installation, precise positioning and bolt fixing can be achieved through the mounting holes, ensuring a firm connection between the melting water tank and the external equipment. After installation, the melting water tank will not shake or shift. This design solves the problems of traditional melting devices lacking a dedicated installation structure, inconvenient disassembly and assembly, and easy shaking after installation leading to loosening of pipes 201 and media leakage. It enables quick, precise disassembly and assembly and stable installation of the melting water tank, facilitating later maintenance and repair of the equipment. Simultaneously, it avoids loosening of pipes 201 and loss of cold air due to installation shaking, ensuring the stability of the melting water tank in use.

[0047] In some embodiments, the water circuit assembly 20 further includes a quick-connect nozzle 24. The quick-connect nozzle 24 is disposed at the end of the pipe 201 away from the melting box 10, and the quick-connect nozzle 24 extends through the insulation layer 40 to the outside of the melting water tank, so as to realize quick connection and sealed coupling between the pipe 201 and the external water circulation system.

[0048] Specifically, quick-connect fitting 24 is located at the end of pipe 201. One end of quick-connect fitting 24 is fixedly connected to pipe 201, and the other end extends outward and directly through the insulation layer 40 to the outside of the melting water tank. The interface specifications of quick-connect fitting 24 are compatible with the interface of the external water circulation system, allowing for direct snap-fit ​​connection. This design, with quick-connect fitting 24 extending through the insulation layer 40, eliminates the need to disassemble the insulation layer 40 when connecting the water circuit assembly 20 to the external water circulation system. The snap-fit ​​connection enables rapid connection, and the sealing structure of quick-connect fitting 24 ensures a tight seal at the connection point, preventing media leakage and cold air leakage. This design solves the problems of cumbersome connection between pipe 201 and the external water circulation system, and cold air loss due to poor sealing at the connection point. It achieves rapid and sealed coupling between the water circuit assembly 20 of the melting water tank and the external water circulation system, improving the efficiency of equipment assembly and commissioning. Simultaneously, it prevents cold air leakage and media seepage at the connection point, ensuring the continuity and stability of the melting medium circulation.

[0049] Optionally, the water circuit assembly 20 also includes an extension pipe. One end of the extension pipe is connected to the end of the return water pipe 22 or the overflow pipe 23, and the other end extends outward and is fixedly connected to a quick-connect fitting 24 located on the outside of the insulation layer 40. The pipe body of the extension pipe at least partially penetrates the receiving gap and is enclosed inside the insulation layer 40. By installing the extension pipe, it is ensured that the cryogenic medium is always under the thermal insulation protection of the insulation layer 40 throughout its entire flow path from the melting box 10 to the external circulation system, effectively preventing localized cold leakage caused by pipe exposure.

[0050] In some embodiments, the assembly process of the above-mentioned melting water tank is as follows: S1: Pre-assemble multiple melting boxes 10, connecting plates 33, overflow pipes 23, quick connectors 24, return pipes 22, and quick connector extension pipes. In this step, the connection between the pipes 201 and the melting boxes 10 is preferably fixed by welding, and a sealant is used for leak-proof sealing, thereby integrating a complete water circulation interface on each independent melting box 10.

[0051] S2: Fix the assembled multiple independent melting units onto the fixed bracket 31 to initially form the overall integrated skeleton of the melting device.

[0052] S3: The integrated frame is further assembled with the spacer support plate 12, the foaming base plate 32, and related fixing components to form the prefabricated device to be foamed. During this process, the arrangement of the spacer support plates 12 defines a uniform accommodating gap between adjacent melting boxes 10.

[0053] S4: Perform overall spatial foaming treatment on the assembled prefabricated device. During the expansion and curing process, the foaming material completely fills the accommodating gap and covers the outer surface of the melting device, ultimately forming an integrated encapsulated insulation layer 40.

[0054] By adopting the above-mentioned process of welding and assembling first and then foaming as a whole, not only is the internal pipeline structure stable, but the airtightness of the insulation space is also guaranteed, thereby effectively isolating the transfer of cold energy and inhibiting the generation of condensation on the outer surface.

[0055] This disclosure also provides a cold precipitation preparation apparatus including: the melting water tank described above.

[0056] Specifically, the melting tank is directly integrated into the frame of the cryoprecipitate preparation instrument. The water circuit component 20 of the melting tank is connected to the external water circulation system of the cryoprecipitate preparation instrument, and the accommodating cavity 11 of the melting tank is compatible with the plasma bag delivery and positioning structure of the cryoprecipitate preparation instrument. The independent melting box 10 structure of the melting tank allows the cryoprecipitate preparation instrument to achieve independent melting of multiple plasma bags without the risk of cross-contamination. The overall foamed insulation layer 40 effectively inhibits condensation on the outer surface of the equipment, preventing condensation dripping into the equipment and causing circuit failures and component corrosion. This solves the problems of cross-contamination of plasma, equipment condensation affecting service life and safety, and low melting efficiency of existing cryoprecipitate preparation instruments. It enables the cryoprecipitate preparation instrument to combine the safety and efficiency of plasma melting with the stability and durability of equipment use, making it suitable for the batch preparation needs of cryoprecipitate in blood banks, medical institutions, and other scenarios.
