Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a water tank system. Background Art

[0002] In open heart surgery supported by extracorporeal circulation, it is necessary to perform precise temperature control on multiple functional modules such as multiple circuits of extracorporeal circulation (main circulation circuit, myocardial perfusion protection circuit), warm blankets for maintaining patient body temperature, and brain protection. In particular, the temperature control required for these modules is quite different, and the temperature needs to be adjusted according to the progress of the operation. For example, the main circulation circuit needs to cool the patient at the beginning of the operation to reduce the patient's oxygen consumption during the operation, and the patient needs to be warmed up at the end of the operation to help the patient's heart beat again. During the whole process, the warm blanket needs a fixed temperature to compensate for the temperature loss caused by the heat dissipation of the patient's body surface, and myocardial protection requires a constant temperature of 4°C. Therefore, when using traditional water tanks in the operating room, additional ice making and ice buckets are usually required to change the temperature. The temperature is uncontrollable and pollution is caused. When using a warm blanket, an additional water tank is required for temperature control, which takes up space and increases the inconvenience of medical staff. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are given in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to understand the disclosure of the present application more thoroughly and comprehensively.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0037] In open heart surgery supported by extracorporeal circulation, it is necessary to perform precise temperature control on multiple functional modules such as multiple circuits of extracorporeal circulation (main circulation circuit, myocardial perfusion protection circuit), warm blankets for maintaining patient body temperature, and brain protection. In particular, the temperature control required for these modules is quite different, and the temperature needs to be adjusted according to the progress of the operation. For example, the main circulation circuit needs to cool the patient at the beginning of the operation to reduce the patient's oxygen consumption during the operation, and the patient needs to be warmed up at the end of the operation to help the patient's heart beat again. During the whole process, the warm blanket needs a fixed temperature to compensate for the temperature loss caused by the heat dissipation of the patient's body surface, and myocardial protection requires a constant temperature of 4°C. Therefore, when using traditional water tanks in the operating room, additional ice making and ice buckets are usually required to change the temperature. The temperature is uncontrollable and pollution is caused. When using a warm blanket, an additional water tank is required for temperature control, which takes up space and increases the inconvenience of medical staff.

[0038] For example, the two commonly used water tanks on the market are single-temperature zone extracorporeal circulation hot and cold water tanks and large extracorporeal circulation hot and cold water tanks. Among them, although the single-temperature zone extracorporeal circulation hot and cold water tank is small in size, it can only provide limited temperature regulation functions; the large extracorporeal circulation hot and cold water tank is large in size, has high power consumption, and has high working noise, which is inconvenient to use beside the bed in the space-constrained cardiac surgery operating room. In addition, due to the volume limitations of the compressor and heating components, large water tanks can usually only set two temperatures, one for the oxygenator as the main circulation temperature control, and the other for the variable temperature blanket temperature. However, the number of temperature zones and regulation capabilities required for additional temperature control with large temperature differences, such as near-freezing point cardioplegia fluid, hypothermia for brain protection, etc., exceed the capabilities of existing water tanks.

[0039] In response to the above problems, an embodiment of the present application provides a water tank system that can provide multiple temperature zones while controlling volume and cost, and can achieve rapid temperature change and precise temperature control.

[0040] Reference Figure 1 In one embodiment, a water tank system is provided, including a first main liquid storage tank 100, a refrigeration component 110, a second main liquid storage tank 200, a heating component 210, and a plurality of sub-liquid storage tanks 300. The capacity of the first main liquid storage tank 100 and the second main liquid storage tank 200 is greater than the capacity of the sub-liquid storage tank 300. The capacity of the first main liquid storage tank 100 and the second main liquid storage tank 200 may be 20L to 30L, and the capacity of the sub-liquid storage tank 300 may be 1L to 2L. The specific capacity setting of each liquid storage tank may be determined according to actual needs, and no specific limitation is made here.

[0041] The first main liquid storage tank 100 can store a first liquid, and the second main liquid storage tank 200 can store a second liquid. The first liquid and the second liquid can be water or other fluids. The refrigeration component 110 can cool the first liquid in the first main liquid storage tank 100, and the heating component 210 can heat the second liquid in the second main liquid storage tank 200. The temperature of the heated second liquid is greater than the temperature of the cooled first liquid. In one embodiment, the temperature of the cooled first liquid is between 0° and 4°, such as 0° or 1° or 2° or 3° or 4°, and the temperature of the heated second liquid is between 55° and 60°, such as 55° or 57° or 59° or 60°. The refrigeration component 110 can use a compressor, etc., as long as it can cool the first liquid. The heating component 210 can use a heating wire, etc., mainly to heat the second liquid.

[0042] The first main liquid reservoir 100 is connected to the first main loop 120, and both ends of the first main loop 120 are connected to the first main liquid reservoir 100. That is, the first liquid in the first main liquid reservoir 100 can flow out to the first main loop 120, and return to the first main liquid reservoir 100 through the first main loop 120. Similarly, the second main liquid reservoir 200 is connected to the second main loop 220, and both ends of the second main loop 220 are connected to the second main liquid reservoir 200. That is, the second liquid in the second main liquid reservoir 200 can flow out to the second main loop 220, and return to the second main liquid reservoir 200 through the second main loop 220.

[0043] In one embodiment, a first main pump 121 is provided in the first main loop 120, and the first main pump 121 is used to control the circulation of the first liquid in the first main loop 120. In this embodiment, the first main pump 121 is provided in the first main loop 120, and the first main pump 121 can pump the first liquid from the first main liquid storage tank 100 to the first main loop 120, and then return to the first main liquid storage tank 100 through the first main loop 120.

[0044] In one embodiment, a second main pump 221 is provided in the second main loop 220, and the second main pump 221 is used to control the circulation of the second liquid in the second main loop 220. In this embodiment, the second main pump 221 is provided in the second main loop 220, and the second main pump 221 can pump the second liquid from the second main liquid storage tank 200 to the second main loop 220, and then return to the first main liquid storage tank 100 through the second main loop 220.

[0045] In this embodiment, each sub-liquid storage tank 300 stores a third liquid and an independently arranged heat transfer pipeline 310. The heat transfer pipeline 310 is connected to the first main circuit 120 through the first liquid inlet pipeline 320 and the first liquid outlet pipeline 330, and the heat transfer pipeline 310 is connected to the second main circuit 220 through the second liquid inlet pipeline 340 and the second liquid outlet pipeline 350. The temperature of the third liquid in each sub-liquid storage tank 300 corresponds to its own temperature range.

[0046] The heat transfer pipeline 310 can be arranged in the third liquid, which has good heat transfer performance. The heat of the fluid in the heat transfer pipeline 310 can be transferred to the third liquid through the heat transfer pipeline 310, thereby realizing the temperature adjustment of the third liquid in each sub-liquid storage tank 300. The heat transfer pipeline 310 in each sub-liquid storage tank 300 is connected to a first liquid inlet pipeline 320, a first liquid outlet pipeline 330, a second liquid inlet pipeline 340 and a second liquid outlet pipeline 350. One end of the first liquid inlet pipeline 320 is connected to an inlet of the heat transfer pipeline 310, and the other end is connected to the first main circuit 120. One end of the first liquid outlet pipeline 330 is connected to an outlet of the heat transfer pipeline 310, and the other end is connected to the first main circuit 120. That is, the first liquid in the first main circuit 120 can enter the heat transfer pipeline 310 through the first liquid inlet pipeline 320, and then return to the first main circuit 120 through the heat transfer pipeline 310 and the first liquid outlet pipeline 330. One end of the second liquid inlet pipeline 340 is connected to an inlet of the heat transfer pipeline 310, and the other end is connected to the second main loop 220. One end of the second liquid outlet pipeline 350 is connected to the first outlet of the heat transfer pipeline 310, and the other end is connected to the second main loop 220. That is, the second liquid in the second main loop 220 can enter the heat transfer pipeline 310 through the second liquid inlet pipeline 340, and then return to the second main loop 220 through the heat transfer pipeline 310 and the second liquid outlet pipeline 350.

[0047] Since the temperature of the first liquid is relatively low and the temperature of the second liquid is relatively high, the two temperatures are different. Therefore, in practical applications, the first liquid or the second liquid with different temperatures can be controlled to enter the heat transfer pipeline 310, so that the liquid in the heat transfer pipeline 310 reaches the required temperature, and then the third liquid in the sub-liquid storage tank 300 is heat-conducted to adjust the temperature of the third liquid. Since each sub-liquid storage tank 300 is provided with an independent heat transfer pipeline 310, the temperature of the liquid in the heat transfer pipeline 310 can be adjusted separately for each sub-liquid storage tank 300, so that the third liquid in each sub-liquid storage tank 300 can reach its required temperature. In this embodiment, the temperature of the third liquid in each sub-liquid storage tank 300 corresponds to its own temperature range, and the temperature of the third liquid in each sub-liquid storage tank 300 can be adjusted to its corresponding temperature range according to actual needs, so as to meet the different requirements for the water tank temperature in different links of the extracorporeal circulation surgery.

[0048] In this embodiment, a first liquid inlet valve 321 may be provided in the first liquid inlet pipeline 320, and a first liquid outlet valve 331 may be provided in the first liquid outlet pipeline 330, so as to facilitate separate control of the liquid inlet of the first liquid inlet pipeline 320 and the liquid outlet of the first liquid outlet pipeline 330. Similarly, a second liquid inlet valve 341 may be provided in the second liquid inlet pipeline 340, and a second liquid outlet valve 351 may be provided in the second liquid outlet pipeline 350, so as to facilitate separate control of the liquid inlet of the second liquid inlet pipeline 340 and the liquid outlet of the second liquid outlet pipeline 350. That is, when it is necessary to heat the third liquid in a certain sub-liquid storage tank 300, the corresponding first liquid inlet valve 321 and the first liquid outlet valve 331 can be closed to stop the first liquid with a lower temperature from entering the heat transfer pipeline 310 in the sub-liquid storage tank 300, and at the same time, the corresponding second liquid inlet valve 341 and the second liquid outlet valve 351 can be opened to allow the second liquid with a higher temperature to enter the heat transfer pipeline 310 in the sub-liquid storage tank 300, thereby effectively and quickly raising the temperature of the liquid in the heat transfer pipeline 310, and quickly raising the temperature of the third liquid through the heat conduction effect of the heat transfer pipeline 310.

[0049] In one embodiment, the first main circuit 120 includes a first liquid outlet section pipeline 122 and a first liquid return section pipeline 123. The first liquid flows out of the first main liquid storage tank 100 and returns to the first main liquid storage tank 100 through the first liquid outlet section pipeline 122 and the first liquid return section pipeline 123 in sequence. The first liquid inlet pipeline 320 is connected to the first liquid outlet section pipeline 122, and the first liquid outlet pipeline 330 is connected to the first liquid return section pipeline 123. That is, after the first liquid flows out of the first main liquid storage tank 100, it can enter the heat transfer pipeline 310 through the first liquid inlet pipeline 320 connected to the first liquid outlet section pipeline 122, thereby improving the efficiency of the first liquid entering the heat transfer pipeline 310. At the same time, the liquid flowing out of the heat transfer pipeline 310 can directly enter the first liquid return section pipeline 123 through the first liquid outlet pipeline 330, thereby accelerating the efficiency of the liquid returning to the first main liquid storage tank 100.

[0050] Similarly, the second main circuit 220 includes a second liquid outlet section pipeline 222 and a second liquid return section pipeline 223. The second liquid flows out of the second main liquid storage tank 200 and returns to the second main liquid storage tank 200 through the second liquid outlet section pipeline 222 and the second liquid return section pipeline 223 in sequence. The second liquid inlet pipeline 340 is connected to the second liquid outlet section pipeline 222, and the second liquid outlet pipeline 350 is connected to the second liquid return section pipeline 223. That is, after the second liquid flows out of the second main liquid storage tank 200, it can enter the heat transfer pipeline 310 through the second liquid inlet pipeline 340 connected to the second liquid outlet section pipeline 222, thereby improving the efficiency of the second liquid entering the heat transfer pipeline 310. At the same time, the liquid flowing out of the heat transfer pipeline 310 can directly enter the second liquid return section pipeline 223 through the second liquid outlet pipeline 350, thereby accelerating the efficiency of the liquid returning to the second main liquid storage tank 200.

[0051] Through the coordinated connection between the above-mentioned pipelines, the liquid can quickly enter the corresponding box or pipeline, thereby effectively improving the temperature adjustment efficiency of the third liquid in each sub-liquid storage tank 300, thereby quickly changing the temperature and accurately controlling the temperature of the third liquid in each sub-liquid storage tank 300.

[0052] In one embodiment, each sub-liquid storage tank 300 is provided with a heat conduction component, the heat conduction component has a heat conduction pipeline 310, and the heat conduction component includes a coil structure or a hollow plate structure. By setting the heat conduction component as a coil structure or a hollow plate structure, the heat exchange area of ​​the heat conduction component can be effectively increased, the heat exchange efficiency can be improved, and sufficient cold and heat exchange can be achieved.

[0053] Reference Figure 2 In one embodiment, the water tank system provided in this embodiment may further include a controller 400, each sub-liquid storage tank 300 is correspondingly provided with a temperature detection component 360 for detecting the temperature of the third liquid, and the controller 400 is respectively connected to each temperature detection component 360, the first liquid inlet valve 321, the first liquid outlet valve 331, the second liquid inlet valve 341 and the second liquid outlet valve 351. Among them, the temperature detection component 360 may be a temperature sensor, and the controller 400 may be a central processing unit. In this embodiment, the controller 400 can obtain the detection result of the temperature detection component 360 in each sub-liquid storage tank 300 and control the switch state of each valve corresponding to each sub-liquid storage tank 300 accordingly, so as to adjust the liquid temperature in each heat transfer pipeline 310, and then adjust the temperature of the third liquid in each sub-liquid storage tank 300.

[0054] Specifically, the controller 400 can be configured to: determine the actual temperature of the third liquid in each sub-liquid storage tank 300 according to the temperature detection results of each temperature detection component 360; for each sub-liquid storage tank 300: if the actual temperature of the third liquid is lower than the lowest temperature value of the temperature range corresponding to it, close the first liquid inlet valve 321 and the first liquid outlet valve 331, and open the second liquid inlet valve 341 and the second liquid outlet valve 351; if the actual temperature of the third liquid is higher than the highest temperature value of the temperature range corresponding to it, open the first liquid inlet valve 321 and the first liquid outlet valve 331, and close the second liquid inlet valve 341 and the second liquid outlet valve 351; if the actual temperature of the third liquid is within the temperature range corresponding to it, close the first liquid inlet valve 321, the first liquid outlet valve 331, the second liquid inlet valve 341 and the second liquid outlet valve 351.

[0055] That is, when the controller 400 detects that the actual temperature of the third liquid in a certain sub-liquid storage tank 300 is lower than the lowest temperature value of the corresponding temperature range, the third liquid needs to be heated. At this time, the first liquid inlet valve 321 and the first liquid outlet valve 331 can be controlled to be closed to prevent the first liquid with a lower temperature from entering the heat transfer pipeline 310. At the same time, the second liquid inlet valve 341 and the second liquid outlet valve 351 are controlled to be opened to allow the second liquid with a higher temperature to enter the heat transfer pipeline 310, thereby heating the third liquid through heat conduction. When the controller 400 detects that the actual temperature of the third liquid in a certain sub-liquid storage tank 300 is higher than the highest temperature value of the corresponding temperature range, the third liquid needs to be cooled. At this time, the second liquid inlet valve 341 and the second liquid outlet valve 351 can be controlled to be closed to prevent the second liquid with a higher temperature from entering the heat transfer pipeline 310. At the same time, the first liquid inlet valve 321 and the first liquid outlet valve 331 are controlled to be opened to allow the first liquid with a lower temperature to enter the heat transfer pipeline 310, thereby cooling the third liquid through heat conduction.

[0056] In addition, when the controller 400 detects that the actual temperature of the third liquid is within the corresponding temperature range, the first liquid inlet valve 321, the first liquid outlet valve 331, the second liquid inlet valve 341 and the second liquid outlet valve 351 can be controlled to be closed, thereby saving heat energy.

[0057] In this embodiment, each sub-liquid storage tank 300 can also be connected to an external pipeline 370, and the third liquid in each sub-liquid storage tank 300 is connected to an external device through the external pipeline 370. That is, according to the liquid temperature required by the external device, the external device can be connected to the corresponding sub-liquid storage tank 300 through the external pipeline 370, so that the third liquid in the sub-liquid storage tank 300 can be output to the external device to achieve heat exchange with the external device. Among them, the external device can include an extracorporeal blood heating heat exchanger, a myocardial arrest fluid cooling heat exchanger, etc., which are not listed here one by one.

[0058] Among them, an external valve 371 is provided in the external pipeline 370. When the third liquid does not need to be output to the outside, the external valve 371 is closed, and when the third liquid needs to be output to the outside, the external valve 371 is opened.

[0059] It should be noted that, in actual applications, the first main liquid storage tank 100, the refrigeration assembly 110, the second main liquid storage tank 200 and the heating assembly 210 in the water tank system provided in this embodiment can be placed outside the operating room, and the low-temperature liquid or high-temperature liquid in each main liquid storage tank can be transported to the operating room through the insulation pipeline. In this way, the fan (especially the refrigeration fan) required to start for heat dissipation during the cooling or heating process can be avoided from disturbing the laminar airflow in the operating room, thereby reducing the risk of infection.

[0060] Reference Figure 3 In another embodiment, a water tank system is also provided, including a first main liquid storage tank 100, a refrigeration assembly 110 and a plurality of sub-liquid storage tanks 300. The refrigeration assembly 110 cools the first liquid in the first main liquid storage tank 100, and the first main liquid storage tank 100 is connected to the first main circuit 120, and both ends of the first main circuit 120 are connected to the first main liquid storage tank 100. A third liquid and an independently arranged heat transfer pipeline 310 are stored in each sub-liquid storage tank 300, and the heat transfer pipeline 310 is connected to the first main circuit 120 through a first liquid inlet pipeline 320 and a first liquid outlet pipeline 330, respectively. Each sub-liquid storage tank 300 is also provided with a corresponding heating assembly 500, and the heating assembly 500 is used to heat the third liquid, and the temperature of the third liquid in each sub-liquid storage tank 300 corresponds to its own temperature range.

[0061] The difference from the water tank system provided in the previous embodiment is that the water tank system in this embodiment cancels the second main liquid storage tank 200 and the second main circuit 220, and instead configures a heating component 500 for each sub-liquid storage tank 300. This is because the heating efficiency is much higher than the cooling efficiency, and the heating process does not require the use of a compressor, and there is no risk of the cooling fan affecting the laminar flow in the operating room. Therefore, a heating component 500 can be separately provided for each sub-liquid storage tank 300, and the third liquid can be heated by the heating component 500. The heating component 500 can include a heating wire, etc. Taking the heating wire as an example, the heating wire can be placed in the sub-liquid storage tank 300 and submerged by the third liquid in the sub-liquid storage tank 300.

[0062] The water tank system provided in this embodiment eliminates the second main liquid storage tank 200 and its corresponding second main circuit 220, thereby reducing the overall volume and total weight, and at the same time, simplifying the control process of each circuit.

[0063] The first liquid cooled by the refrigeration component 110 can enter the heat transfer pipeline 310 in each sub-liquid storage tank 300 through the first main circuit 120 and the first liquid inlet pipeline 320. The first liquid conducts heat to the third liquid in the sub-liquid storage tank 300 through the heat transfer pipeline 310 to reduce the temperature of the third liquid. The first liquid in the heat transfer pipeline 310 can return to the first main circuit 120 through the first liquid outlet pipeline 330 connected to the heat transfer pipeline 310, and finally return to the first main liquid storage tank 100. At the same time, the heating component 500 corresponding to each sub-liquid storage tank 300 can heat the third liquid in the sub-liquid storage tank 300 to increase the temperature of the third liquid. In this way, the temperature of the third liquid in each sub-liquid storage tank 300 can be flexibly adjusted so that the third liquid in each sub-liquid storage tank 300 is within its respective temperature range.

[0064] For the specific contents of the first main liquid storage tank 100, the first main circuit 120, the first liquid inlet pipeline 320, the first liquid outlet pipeline 330, each sub-liquid storage tank 300 and the heat transfer pipeline 310, please refer to the specific description of the water tank system provided in the above embodiment, which will not be repeated here.

[0065] It should be noted that, in the present embodiment, since the second main liquid storage tank 200 and the second main circuit 220 are eliminated, there is no risk of mixing of the first liquid and the second liquid. Therefore, it is only necessary to set the first liquid inlet valve 321 in the first liquid inlet pipeline 320, and there is no need to set the first liquid outlet valve 331 in the first liquid outlet pipeline 330, thereby simplifying the overall structure and the valve control process.

[0066] In one embodiment, the water tank system provided in this embodiment further includes a power supply module, which is connected to each heating component 500 respectively, and a power switch 510 is provided between each heating component 500 and the power supply module. The power supply module can supply power to each heating component 500, thereby making the heating component 500 work. By controlling the power switch 510 corresponding to each heating component 500, it is possible to flexibly control whether the heating component 500 corresponding to each sub-liquid storage tank 300 works or not, thereby realizing flexible control of the temperature of the third liquid in each sub-liquid storage tank 300.

[0067] In one embodiment, the power supply module includes a first end and a second end, the heating assembly 500 includes a first end and a second end, the first end of the power supply module is connected to the first end of each heating assembly 500 through a power switch 510, and the second end of the power supply module is connected to the second end of each heating assembly 500. Thus, the power supply module and each heating assembly 500 form a power supply loop.

[0068] Reference Figure 4 In this embodiment, the controller 400 can be electrically connected to the temperature detection component 360, the first liquid inlet valve 321 and the power switch 510 corresponding to each sub-liquid storage tank 300, and then the detection result of the temperature detection component 360 in each sub-liquid storage tank 300 can be obtained and the switch state of the first liquid inlet valve 321 corresponding to each sub-liquid storage tank 300 and the switch state of the power switch 510 corresponding to each heating component 500 can be controlled accordingly, so as to adjust the liquid temperature in each heat conduction pipeline 310, and then adjust the temperature of the third liquid in each sub-liquid storage tank 300.

[0069] Specifically, the controller 400 may be configured to determine the actual temperature of the third liquid in each sub-liquid storage tank 300 according to the temperature detection result of each temperature detection component 360. For each sub-liquid storage tank 300: if the actual temperature of the third liquid is lower than the lowest temperature value of the temperature interval corresponding to it, the first liquid inlet valve 321 is closed, and the power switch 510 corresponding to the heating component 500 in the sub-liquid storage tank 300 is turned on, so as to control the heating component 500 to heat the third liquid. If the actual temperature of the third liquid is higher than the highest temperature value of the temperature interval corresponding to it, the first liquid inlet valve 321 is opened, and the power switch 510 corresponding to the heating component 500 in the sub-liquid storage tank 300 is turned off, so as to introduce the first liquid with a lower temperature, and then cool the third liquid in the sub-liquid storage tank 300 through heat conduction. If the actual temperature of the third liquid is within the temperature interval corresponding to it, the first liquid inlet valve 321 and the power switch 510 corresponding to the heating component 500 in the sub-liquid storage tank 300 are turned off.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.

It should be noted that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
