Description

Technical Field

[0001] This invention belongs to the field of heat exchange technology, and specifically relates to a high-flow-rate heat exchange circulation system. Background Technology

[0002] Extracorporeal membrane oxygenation (ECMO) is primarily used to provide continuous extracorporeal respiration and circulation for patients with severe cardiopulmonary failure, thus sustaining their lives. The heat exchange circulation system is a core component of the ECMO system, its main function being to provide warmed, cooled, and raw water to the extracorporeal blood circulation system. Specifically, when the patient's blood circulates outside the body, the heat exchange circulation system maintains a suitable blood temperature, consistent with the body temperature, ensuring normal oxygenation and carbon dioxide removal during extracorporeal circulation.

[0003] Currently, ECMO heat exchange water tanks on the market are typically small in size and have low flow rates, resulting in low heat exchange efficiency and difficulties in draining the piping system. Conversely, high-flow-rate tanks are generally large in size. This is because high flow rates require a large-volume storage tank to ensure the proper operation of the high-flow magnetic pump. Small flow rates are generally around 1.6 L / min, while high flow rates are typically greater than 10 L / min. Small tanks are generally smaller than 400 mm * 300 mm * 300 mm, while large tanks are generally around 660 mm * 450 mm * 810 mm.

[0004] In a conventional circulation pipeline, the water circulates through the load end, returns to the storage tank, mixes, and is then heated / cooled by a heat exchanger before being output to the load end. This circulation method reduces the efficiency of water temperature control and consumes more energy for temperature control because the water is mixed in the storage tank each time.

[0005] To address the aforementioned technical challenges, the aim is to increase the flow rate of the heat exchange circulation system while maintaining a small size and weight. However, this improvement faces new challenges: the pre-charging of the circulation pipeline system is difficult, and internal gases are hard to expel, which can cause the magnetic pump to have difficulty starting properly, reducing heat exchange efficiency. Summary of the Invention

[0059] In view of this, the purpose of the present invention is to provide a high-flow-rate heat exchange circulation system that can reduce the difficulty of pre-charging the circulation system, ensure the smooth discharge of gas inside the circulation system, and effectively improve the heat exchange efficiency.

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Please refer to [the accompanying drawings]. Figures 1 to 10 .

[0061] Please refer to Figures 1 to 6 The high-flow heat exchange circulation system disclosed in this embodiment of the invention includes a water storage tank 100, a partition plate 200, a heat exchanger 300, a circulation pipeline 500, and a temperature regulating device 600. One end of the circulation pipeline 500 is connected to the heat exchanger 300, and the other end is connected to the load.

[0062] The partition plate 200 is disposed inside the water storage tank 100, dividing the water storage tank 100 into a first chamber and a second chamber arranged vertically. The first chamber is used to store circulating water, and the heat exchanger 300 is at least partially disposed in the second chamber. The partition plate 200 has a notch 201 to connect the first chamber and the second chamber. The water storage tank 100 is provided with a water inlet 101 that communicates with the first chamber. A side partition plate 105 is disposed inside the water storage tank 100. The side partition plate 105 and part of the inner wall of the water storage tank 100 form a partition area 107. The top is connected to the first chamber, the bottom of the partition 107 is connected to the flow channel of the heat exchanger 300, the heat exchanger 300 is provided with a water inlet area, the water inlet area, the partition 107 and the notch 201 are all provided accordingly, the lower end face of the side partition 105 and the partition 200 have a water replenishment gap 106 for circulating water to pass through, the water replenishment gap 106 is connected to the notch 201; one end of the circulation pipe 500 is connected to the heat exchanger 300, and the other end is connected to the load, and the temperature regulating device 600 is provided at the lower part of the heat exchanger 300 for regulating the temperature of the heat exchanger 300.

[0063] During the initial pre-charge cycle of the heat exchange circulation system, circulating water needs to be injected into the water storage tank 100 through the water inlet 101. The circulating water enters the first chamber and then enters the partition zone 107 corresponding to the gap 201 through the water replenishment gap 106. It then enters the flow channel of the heat exchanger 300 through the water inlet area. The circulating water in the flow channel of the heat exchanger 300 enters the load through the circulation pipeline to form a circulation. The gas in the circulation pipeline 500 and the flow channel of the heat exchanger 300 floats to the surface through the partition zone 107, overflows the water surface at the top of the partition zone 107, enters the first chamber, and finally exits the water storage tank 100 through the water inlet 101. After the gas inside the heat exchange circulation system is purged, normal water circulation can be carried out to achieve heat exchange. The temperature of the heat exchanger 300 is adjusted by the temperature regulating device 600 to meet the heat exchange requirements.

[0064] Compared with the prior art, the high-flow-rate heat exchange circulation system disclosed in the embodiments of the present invention can greatly reduce the pre-charging difficulty of the circulation system while maintaining the small volume, small weight and high flow rate of the heat exchange circulation system, ensuring that the gas inside the circulation system is discharged smoothly and quickly, and effectively improving the heat exchange efficiency.

[0065] The partition plate 200 can also isolate the water after heat exchange from the circulating water in the water storage tank 100 through the heat exchanger 300, so as to avoid heat exchange between the water in the water storage tank 100 and the circulating water in the heat exchanger 300, thereby further improving the heat exchange efficiency.

[0066] It should be noted that the load in this embodiment of the invention is a membrane oxygenator.

[0067] As a further embodiment, the side partition 105 disclosed in this embodiment of the invention includes a first side partition 1051 and a second side partition 1052. The bottom of the second side partition 1052 is connected to the partition plate 200, and the top of the second side partition 1052 has a first gap with the top of the water storage tank 100.

[0068] The bottom of the first side partition 1051 and the partition plate 200 have a water replenishment gap 106, and the top of the first side partition 1051 and the top of the water storage tank 100 have a second gap.

[0069] The first gap and the second gap may be equal or unequal.

[0070] It should be noted that the first side partition 1051 and the second side partition 1052 are vertically connected. One side wall of the first side partition 1051 is connected to one side wall of the water storage tank 100, and one side wall of the second side partition 1052 is connected to the adjacent side wall of the water storage tank 100 that is connected to the side wall of the water storage tank 100 that is connected to the first side partition 1051.

[0071] As a specific embodiment of the present invention, the first gap and the second gap disclosed in the embodiments of the present invention are equal, and both the first gap and the second gap are 1mm-3mm.

[0072] The distance between the top of the partition zone 107 and the top wall of the water storage tank 100 can be 1mm, 2mm, 2.5mm, or 3mm. This arrangement allows the gas discharged from the partition zone 107 to smoothly enter the first chamber of the water storage tank 100.

[0073] It should be noted that the water inlet 101 on the water storage tank 100 is located near the notch 201. With this configuration, water injected from the water inlet 101 can quickly enter the partition area 107 through the water replenishment gap 106.

[0074] As a further embodiment, the high-flow-rate heat exchange circulation system disclosed in this embodiment of the invention also includes a UVC sterilization component 102.

[0075] Please refer to the following for details. Figure 7 The UVC sterilization component 102 includes a fixing part 1021 and a sterilization part. The fixing part 1021 is fixed to the water storage tank 100, and the sterilization part extends into the first chamber.

[0076] The sterilization section includes an LED bead 1022 with sterilization and disinfection function disposed on the fixing part 1021, and a lamp cover 1023. The LED bead 1022 is fixed on the fixing part 1021, and the lamp cover 1023 covers the LED bead 1022.

[0077] It should be noted that the lampshade 1023 is made of highly transparent quartz glass.

[0078] Among them, the UVC sterilization component 102 uses high-power lamp beads, and the light power of one UVC sterilization component 102 can reach 500mW.

[0079] When the UVC sterilization component 102 is turned on, the UVC light emitted by the LED beads 1022 passes through and reaches the circulating water that needs to be sterilized, thus sterilizing and disinfecting the circulating water in the water storage tank 100.

[0080] The embodiments of the present invention do not limit the specific configuration of the UVC sterilization component 102. Any configuration that meets the requirements of the present invention is within the protection scope of the present invention.

[0081] In one embodiment, the UVC sterilization component 102 disclosed in this invention is a single unit, fixed to the top of the water storage tank 100 and correspondingly positioned to the partition zone 107. This configuration enables real-time disinfection of the water within the partition zone 107. Experimental verification shows that the UVC sterilization component 102 can achieve a 99% sterilization rate for circulating water.

[0082] As another embodiment, the UVC sterilization component 102 disclosed in this embodiment of the invention is at least two, wherein one UVC sterilization component 102 is fixed to the top of the water storage tank 100 and is provided in the corresponding partition area 107, and at least one UVC sterilization component 102 is provided on at least one side of the water storage tank 100.

[0083] In other words, a UVC sterilization component 102 can be installed on one side of the water storage tank 100, or a UVC sterilization component 102 can be installed on both sides, three sides or four sides of the water storage tank 100. The number of components installed on each side of the water storage tank 100 can be one or more, and those skilled in the art can choose according to actual needs.

[0084] As a further embodiment, the heat exchange circulation system disclosed in this invention also includes a one-way valve 103. The one-way valve 103 is disposed on the water storage tank 100, with its outlet end connected to the first chamber and its inlet end connected to the outside. This configuration ensures that the one-way valve 103 can only flow unidirectionally from the outside to the inside of the water storage tank 100, preventing water overflow from the tank and preventing negative pressure from forming inside the tank, thus preventing water from participating in circulation.

[0085] As a further embodiment, the heat exchange circulation system disclosed in this invention also includes a seal 400, wherein the seal 400 is disposed between the bottom of the water storage tank and the heat exchanger 300, and the seal 400 is a frame-shaped structure conforming to the heat exchanger 300. This arrangement effectively blocks leakage paths in the water circuit (such as heating water, cooling water, and raw water), thereby ensuring the safe operation of the heat exchange circulation system.

[0086] The specific material of the sealing element 400 is not limited in the embodiments of the present invention. The sealing element 400 may be made of rubber, silicone or other materials. Any material that meets the requirements of the present invention is within the protection scope of the present invention.

[0087] As a preferred embodiment, the sealing element 400 disclosed in this embodiment of the invention is preferably made of silicone.

[0088] The embodiments of the present invention do not limit the specific structure of the temperature regulating device 600. Any structure that meets the requirements of the present invention is within the protection scope of the present invention.

[0089] As one embodiment, please refer to Figure 2 The temperature regulating device 600 disclosed in the embodiments of the present invention includes a heat sink 601, a TEC cooling chip 602 and a temperature controller, wherein the TEC cooling chip 602 and the temperature controller are electrically connected.

[0090] Specifically, the heat sink 601 includes heat dissipation fins 6011 and axial fans 6012. There are at least two axial fans 6012, which are respectively located at both ends of the heat dissipation fins 6011.

[0091] The TEC cooling chip 602 includes a first end face and a second end face. The first end face is in contact with the heat exchanger 300, and the second end face is in contact with the heat dissipation teeth 6011.

[0092] It should be explained that TEC is an abbreviation for Thermoelectric Cooler, a specific name for semiconductor thermoelectric coolers. Based on the Peltier effect, it uses direct current to drive N-type and P-type semiconductor thermocouples to achieve directional heat transfer (heat absorption on the cold side and heat release on the hot side). It is currently the most mature and widely used type of cooler.

[0093] The thermostat controls the current direction of the TEC cooler 602 to heat or cool either its first or second end face. Based on the characteristics of the TEC cooler 602, when the first end face is heated, the second end face is cooled, and vice versa. Through heat conduction via the TEC cooler 602, the heat exchanger 300 is heated or cooled, thus achieving rapid heating or cooling of the circulating water. This design not only reduces the overall volume of the heat exchange cycle system but also lowers noise and improves the safety of the entire system operation.

[0094] It should be noted that when the first end face of the TEC cooler 602 needs to be cooled, the heat dissipation teeth 6011 of the heat sink 601 and the axial fans 6012 at both ends can quickly dissipate the heat from the second end face of the TEC cooler 602 to the external environment.

[0095] In order to fix the TEC cooling chip 602, the high-flow heat exchange circulation system disclosed in the embodiments of the present invention also includes a heat insulation sponge 700, wherein the heat insulation sponge 700 is disposed on the heat sink 601.

[0096] As a specific embodiment, the heat insulation sponge 700 disclosed in this invention includes multiple partition frames, wherein each partition frame contains a TEC cooling element 602. The heat insulation sponge 700 not only provides heat insulation separation for each TEC cooling element 602, but also serves to position and install the TEC cooling elements 602.

[0097] The specific structure of the heat exchanger 300 is not limited in the embodiments of the present invention. The heat exchanger 300 can be a single-channel structure or a double-channel structure. Any structure that meets the requirements of the present invention is within the protection scope of the present invention.

[0098] For a preferred embodiment of the present invention, please refer to Figure 8 The heat exchanger 300 disclosed in this embodiment of the invention has a dual-channel serpentine structure. This design maximizes the reduction of flow resistance and enables uniform and precise control of the circulating water temperature.

[0099] It should be noted that the circulation pipeline 500 disclosed in this embodiment of the invention includes a device inlet pipe 501, a device outlet pipe 502, a connecting pipe 503, a magnetic pump 504, a first quick-connect connector 5011, and a second quick-connect connector 5021. One end of the device inlet pipe 501 is connected to the first quick-connect connector 5011, and the other end is connected to the inlet of the heat exchanger 300. One end of the device outlet pipe 502 is connected to the second quick-connect connector 5021, and the other end is connected to the outlet of the magnetic pump 504. One end of the connecting pipe 503 is connected to the outlet of the heat exchanger 300, and the other end is connected to the inlet of the magnetic pump 504. Both the first quick-connect connector 5011 and the second quick-connect connector 5021 are leak-free, pressurized, medical-grade quick-connect connectors.

[0100] The circulating water injected from the water inlet 101 into the water storage tank 100 enters the partition zone 107 through the water replenishment gap 106, and then enters the water inlet area of ​​the heat exchanger 300 through the partition zone 107. After the circulating water fills the heat exchanger 300, it passes through the connecting pipe 503, the magnetic pump 504, the equipment outlet pipe 502, and the second quick connector 5021 in sequence to enter the load. It then enters the first quick connector 5011 and the equipment inlet pipe 501 through the load, and then enters the heat exchanger 300 again through the equipment inlet pipe 501 to achieve circulation.

[0101] It should be noted that the heat exchanger 300 is provided with a first connection hole communicating with the equipment inlet pipe 501, and the water storage tank 100 is provided with a second connection hole communicating with the equipment outlet pipe 502. The first connection hole is located at the bottom of the heat exchanger 300, and the second connection hole is located at the bottom of the water storage tank 100. With this configuration, the entire circulation pipeline 500 system follows the principle of high to low flow of circulating water, and most of the water in the entire circulation pipeline 500, the water storage tank 100, and the heat exchanger 300 can be automatically and smoothly discharged through the equipment inlet pipe 501 and the equipment outlet pipe 502 solely by gravity.

[0102] As a further embodiment, the heat exchange circulation system disclosed in this invention also includes a bubble monitoring component 505, which is disposed on the outlet pipe 502 of the device. This configuration allows for real-time monitoring of bubbles inside the circulation pipe 500 during the initial venting process. Once no bubbles are detected, the pre-charging is complete, and the system can be used in normal operating mode.

[0103] Please refer to Figure 9 The bubble monitoring component 505 disclosed in this embodiment of the invention includes a bubble monitoring body 5051 and a cover 5052. The bubble monitoring body 5051 has a through hole 5053 for the water outlet pipe 502 of the device to pass through, and transducer plates 5054 are respectively provided on opposite sides of the through hole 5053.

[0104] Among them, the 5054 transducer is an electronic component that can realize the conversion between different forms of energy. Its core function is to convert one form of energy (such as electrical energy, mechanical energy, sound energy, etc.) into another form of energy.

[0105] This bubble monitoring component utilizes the principle of ultrasound. If bubbles are present in the liquid, the ultrasonic waves emitted by the transducer 5054 will be scattered, reflected, or absorbed, thereby changing the propagation path and speed. By measuring parameters such as the propagation time, reflection intensity, and scattering angle of the ultrasonic waves, the presence, size, and number of bubbles can be determined. After the heat exchange circulation system is started and venting occurs for a period of time until no bubbles are detected, it indicates that the circulation pipeline system has been pre-charged. Tightening the water inlet cap on the water inlet 101 allows the high-flow-rate heat exchange circulation system to operate normally.

[0106] As a further embodiment, the high-flow-rate heat exchange circulation system disclosed in this invention also includes a drainage and drying component 506, which is disposed between the water inlet pipe 501 of the equipment. With this configuration, after use, opening the drainage and drying component 506 can drain and dry the residual water inside the high-flow-rate heat exchange circulation system, effectively preventing the growth of bacteria.

[0107] Please refer to Figure 10 The drainage drying assembly 506 includes a three-way solenoid valve 5062 and a vortex fan 5061. The three-way solenoid valve 5062 includes a first port 5063, a second port 5064 and a third port 5065. The first port 5063 is connected to the vortex fan 5061, the second port 5064 is connected to the first quick connector 5011, and the third port 5065 is connected to the heat exchanger 300.

[0108] When the heat exchange circulation system is started and operating normally, the first port 5063 of the three-way solenoid valve 5062 remains closed, and water enters the heat exchanger 300 from the load through the first quick-connect fitting 5011, the second port 5064, and the third port 5065. After use, the load connection is disconnected, and after the heat exchange circulation system automatically drains most of the circulating water by gravity, the first port 5063 is opened, the first quick-connect fitting 5011 is kept closed, the second quick-connect fitting 5021 is kept open, and the vortex fan 5061 is turned on. Under the action of the vortex fan, the residual water in the heat exchange circulation system can be drained and dried through the third port 5065. Finally, the first quick-connect fitting 5011 is kept open, the second quick-connect fitting 5021 is kept closed, and the vortex fan 5061 is turned on to drain and dry the residual water between the first quick-connect fitting 5011 and the second port 5064, thereby preventing the growth of bacteria.

[0109] In order to improve the airtightness of the circulation pipeline 500, the high-flow heat exchange circulation system disclosed in this embodiment of the invention further includes a first elbow 301 and a second elbow 302, wherein the first elbow 301 connects the water inlet of the heat exchanger 300 to the equipment water inlet pipe 501, and the second elbow 302 connects the water outlet of the heat exchanger 300 to the connecting pipe 503.

[0110] As a further embodiment, the heat exchange circulation system disclosed in this invention also includes a temperature sensor 104, which is positioned near the outlet of the heat exchanger 300. The temperature sensor 104 measures the outlet water temperature of the heat exchanger 300 to monitor the circulating water temperature.

[0111] As a further embodiment, the heat exchanger 300 disclosed in this embodiment of the invention has a height difference L between its outlet and the inlet of the magnetic pump 504, where L ≥ 70 mm. This arrangement allows for the expulsion of gas from inside the magnetic pump 504 under the influence of water pressure differential, ensuring that the inner cavity of the magnetic pump 504 is filled with water for smooth startup.

[0112] As a further embodiment, the present invention also discloses a U-shaped liquid level gauge 800, wherein one end of the U-shaped liquid level gauge 800 is connected to the top end of the first chamber, and the other end is connected to the bottom end of the first chamber.

[0113] When the U-shaped level gauge 800 is connected to the water storage tank 100, the liquid inside the U-shaped level gauge 800 and the liquid inside the water storage tank 100 form a connected fluid system. Under the balance of gravity and pressure, the liquid levels of both will remain at the same level. Therefore, by reading the liquid level on one side of the U-shaped level gauge 800, the liquid level in the water storage tank 100 can be directly determined.

[0114] As a further embodiment, the heat exchange circulation system disclosed in this invention further includes a first connector 801 and a second connector 802, wherein the lower end of the U-shaped level gauge 800 is connected to the first connector 801 via a first silicone hose, and the upper end of the U-shaped level gauge 800 is connected to the second connector 802 via a second silicone tube. This configuration improves the airtightness of the connection between the U-shaped level gauge 800 and the water storage tank 100.

[0115] The heat exchanger 300 disclosed in this embodiment of the invention is made of aluminum.

[0116] It should be noted that the no-load flow rate of the high-flow-rate heat exchange circulation system disclosed in the embodiments of the present invention is greater than 13 L / min.

[0117] It should be noted that, in the high-flow-rate heat exchange circulation system disclosed in the embodiments of the present invention, the temperature of the heat exchange circulation system drops from 35°C to 15°C in less than 8 minutes in an environment of 20°C to 25°C; and the temperature of the heat exchange circulation system rises from 15°C to 35°C in less than 3 minutes in an environment of 20°C to 25°C.
