[0002] With my country's continuous progress in the field of mechanically assisted circulation, ECMO (extracorporeal membrane oxygenation) has developed rapidly in recent years. Consequently, the localization of ECMO equipment has made significant progress, with positive advancements in centrifugal pumps, heparinized tubing, and long-acting membrane lungs.

[0003] Currently, ECMO water tanks all use refrigerant cooling, which is a relatively simple cooling method. Its engineering design is relatively complex, resulting in a high failure rate and cost. The overall cooling efficiency is low, and its practicality is limited. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model provides an ECMO water tank that can be cooled using refrigerant and cooling elements. The cooling method can be selected according to actual conditions, and it has the advantage of high cooling efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An ECMO water tank includes:

[0007] Box;

[0008] A temperature control tube is coiled inside the housing and has an input interface and an output interface for circulating connection to external refrigeration equipment.

[0009] A refrigeration element is disposed on the top of the housing and is in contact with the top surface of the housing;

[0010] A heat dissipation component is disposed above the cooling element to dissipate heat and cool the cooling element.

[0011] In one possible implementation, the refrigeration element includes a Peltier temperature control plate having a first temperature control surface and a second temperature control surface, the first temperature control surface being in contact with the top surface of the housing.

[0012] In one possible implementation, the heat dissipation component includes heat dissipation fins that are in contact with the second temperature control surface, and the heat dissipation fins are used to dissipate heat and cool the second temperature control surface.

[0013] In one possible implementation, a reinforcing plate is integrally provided on both sides of the heat dissipation fins, and a fan is provided above the heat dissipation fins, with the fan connected and installed to the two reinforcing plates.

[0018] This utility model has the following advantages due to the adoption of the above technical solution:

[0030] With my country's continuous progress in the field of mechanically assisted circulation, ECMO (extracorporeal membrane oxygenation) has experienced rapid development recently. Consequently, the localization of ECMO equipment has made significant progress, with positive advancements in centrifugal pumps, heparinized tubing, and long-acting membrane lungs. However, current ECMO tanks all use refrigerant cooling, a relatively simple cooling method. This leads to complex engineering designs, resulting in high failure rates and costs, low overall cooling efficiency, and limited practicality. To address these technical problems, this invention provides an ECMO tank that utilizes refrigerant and cooling elements for cooling. The cooling method can be selected according to actual conditions, offering the advantage of high cooling efficiency. The technical solution of this invention will be described in detail below with specific examples.

[0031] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, the ECMO water tank involved in this utility model includes a tank body 1, a temperature control tube 2, a refrigeration element 3, and a heat dissipation assembly 4. The temperature control tube 2 is coiled inside the tank body 1 and has an input interface 21 and an output interface 22 for cyclic connection to external refrigeration equipment.

[0032] The cooling element 3 is located on the top of the housing 1, and is in contact with the top surface of the housing 1. The heat dissipation assembly 4 is located above the cooling element 3 to dissipate heat and cool the cooling element 3.

[0033] It should be noted that the ECMO tank primarily serves to provide a stable temperature regulation system, supplying warming, cooling, and raw water to the extracorporeal blood heat exchanger. This ensures that blood temperature can be regulated during extracorporeal cardiopulmonary support (ECMO), which is especially important for patients with severe cardiopulmonary failure. During use, the temperature of the liquid in the tank needs to be adjusted according to the specific requirements on-site.

[0034] For example, in this embodiment, the device employs two temperature control methods. One method is temperature control via a temperature control tube 2. In actual use, an external refrigeration device needs to be connected through the input interface 21 and output interface 22. The refrigeration device controls the temperature of the refrigerant, and finally, the temperature of the liquid inside the housing 1 is controlled by the temperature control tube 2, which is coiled inside the housing 1. The other temperature control method is control via a refrigeration element 3. In actual use, the refrigeration element 3 needs to be powered. One side of the refrigeration element 3 cools, while the other side dissipates heat. The refrigeration element 3 cools the housing 1, while the heat dissipation component 4 dissipates heat to the other side of the refrigeration element 3. These two temperature control methods can be used individually or in combination, depending on the situation. This structural arrangement provides an ECMO water tank that can be cooled by refrigerant and the refrigeration element 3. The cooling method can be selected according to the actual situation, offering the advantage of high cooling efficiency.

[0035] In this embodiment, specifically, the temperature control medium introduced into the temperature control tube 2 is pentylene glycol. Pentylene glycol is inexpensive, has high cooling and heating efficiency, and is a food-grade substance (medical safe), thus exhibiting high stability in use.

[0036] In this embodiment, specifically, the cooling element 3 includes a Peltier temperature control plate, which has a first temperature control surface 31 and a second temperature control surface 32. The first temperature control surface 31 is attached to the top surface of the housing 1. Peltier is a semiconductor material and has the physical characteristic of "heating in the forward direction and cooling in the reverse direction" when energized.

[0037] In this embodiment, the overall structure of the heat dissipation component 4 is further refined. The heat dissipation component 4 includes heat dissipation fins 41, which are attached to the second temperature control surface 32. The heat dissipation fins 41 are used to dissipate heat and cool the second temperature control surface 32.

[0038] In this embodiment, it is preferable that both sides of the heat dissipation fins 41 are integrally provided with reinforcement plates 42, and a fan 43 is provided above the heat dissipation fins 41, with the fan 43 connected and installed with the two reinforcement plates 42.

[0039] The fan 43 can further improve the heat dissipation efficiency of the cooling element 3, thereby further optimizing the cooling effect of the device. When the cooling demand is high, the second temperature control surface 32 of the cooling element 3 will generate a lot of heat. By combining the fan 43 with the heat dissipation fins 41, the heat dissipation effect of the second temperature control surface 32 can be greatly improved.

[0040] In this embodiment, the specific installation structure of the fan 43 is further refined. Each of the strength plates 42 is provided with a buckle 44, which is slidably connected to the strength plate 42. The two sides of the fan 43 are connected to the strength plate 42 through two buckles 44.

[0041] Specifically, a groove 45 is provided on the strength plate 42, and the buckle 44 is slidably connected to the strength plate 42 through the groove 45.

[0042] The connection structure between the clip 44 and the slide 45 allows the fan 43 to have adjustable position. In actual use, the operator can adjust the position of the fan 43 according to the specific heat output of the second temperature control surface 32. For example, as the usage time increases, the heat output on the second temperature control surface 32 may become uneven when the cooling element 3 is cooling, with some areas accumulating more heat. At this time, the operator can move the fan 43 to a suitable position according to the actual situation to improve the heat dissipation effect of that part.

[0043] In addition, by pre-setting the overall structural dimensions of the fan 43 and the cooling element 3, two fans 43 can be added for air cooling. The sliding connection structure achieved by the buckle 44 and the slide 45 allows the air cooling effect of the device to have high flexibility in use.

[0044] In this embodiment, specifically, both sides of the slide groove 45 are through-holes, so that the buckle 44 can disengage from the end of the slide groove 45 from the strength plate 42, which facilitates the installation and disassembly of the components of the fan 43.

[0045] In one embodiment, the outer side of the strength plate 42 is provided with a connecting buckle 46, the connecting buckle 46 is for connecting strap to connect, and the two ends of the connecting strap pass over the bottom of the box 1 and are respectively connected to two symmetrical connecting buckles 46.

[0046] When cooling regulation of cabinet 1 is required:

[0047] Depending on the actual situation, you can choose to regulate the temperature control tube 2, regulate the refrigeration element 3, or regulate the temperature control tube 2 and the refrigeration element 3 together.

[0048] When the temperature control tube 2 is used for regulation, an external refrigeration device needs to be connected through the input interface 21 and the output interface 22. The refrigeration device controls the temperature of the refrigerant, and finally the temperature of the liquid in the box 1 is regulated through the temperature control tube 2.

[0049] When the cooling element 3 is regulated, it is powered on. One side of the cooling element 3 cools while the other side dissipates heat. The cooling element 3 cools the housing 1, while the heat dissipation assembly 4 dissipates heat on the other side of the cooling element 3. When installing the heat dissipation fins 41, the heat dissipation fins 41 are first placed on the second temperature control surface 32 and made to fit against it. Then, the connecting strap is connected by the connecting buckles 46 of the two side strength plates 42. The connecting strap crosses the bottom of the housing 1. After tightening the connecting strap, the heat dissipation fins 41 can be installed and fixed on the second temperature control surface 32. If it is necessary to add a fan 43 to improve the heat dissipation efficiency, the buckles 44 on both sides of the fan 43 are slid into the slide groove 45 through the end of the slide groove 45, and the position of the fan 43 is adjusted according to the heat dissipation of the second temperature control surface 32.

[0050] When heating control of enclosure 1 is required:

[0051] Discontinue the temperature control tube 2, remove the heat dissipation component 4, and reverse the power interface of the Peltier temperature control board. Then power on the Peltier temperature control board. At this time, the first temperature control surface 31 of the Peltier temperature control board heats up, while the second temperature control surface 32 cools down, thereby realizing the heating control of the cabinet 1.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
