Description

Technical Field

[0001] The utility model belongs to the technical field of medical temperature control systems, and particularly relates to a temperature control device. Background Art

[0002] In the technical field of medical temperature control systems, the main function of a medical temperature control system is to control the body temperature of a patient and maintain a constant temperature. This is very important for certain medical scenarios, such as during surgery, postpartum recovery, hypothermia therapy, etc. By monitoring the patient's body temperature and adjusting according to the set target temperature, the temperature control system can provide a constant temperature environment to ensure that the patient's body temperature is in a safe and ideal state.

[0003] Medical temperature control systems usually use a water circuit circulation for heat transfer. Before temperature control, the gas in the water circuit circulation needs to be discharged. The presence of bubbles will affect the working effect and accuracy of the temperature control system, which may lead to unstable or inaccurate temperature control, thus affecting the treatment effect and safety of the patient.

[0004] In related technologies, an external circulation connected to a water tank is adopted. Although it can completely remove water circuit bubbles, it will also have a certain impact on the temperature control accuracy. When an internal circulation method is adopted, with the liquid path connected to the water tank on one side only, although the temperature control accuracy is greatly improved, the discharge of water circuit bubbles is not sufficient, resulting in a large number of bubbles in the water blanket, which is not conducive to treatment. Summary of the Utility Model

[0005] The technical object of the utility model is to provide a temperature control device, aiming to solve the problems that bubbles cannot be completely removed inside the device and the temperature control accuracy is not high.

[0012] In some embodiments of the present utility model, the heights of the third valve port and the fourth valve port are the same or different.

[0013] In some embodiments of the present utility model, the temperature control component includes a heat exchanger and a refrigerating member, the heat exchanger is used for exchanging the heat of the circulating liquid, the refrigerating member is used for discharging the heat of the circulating liquid, the temperature control device has an exhaust state and a temperature control state. When the temperature control device is in the exhaust state, the circulating liquid flows from the second valve port to the power source and the temperature control component, the air in the temperature control device moves from the first valve port to the liquid storage tank, and the liquid storage tank, the valve body, the power source, the refrigerating member and the heat exchanger are connected to form a closed exhaust circuit. When the temperature control device is in the temperature control state, the air in the temperature control component is discharged, and the power source, the refrigerating member, the heat exchanger and the valve body are connected to form a closed temperature control circuit.

[0014] In some embodiments of the present utility model, in the temperature control circuit, along the flow direction of the circulating liquid:

[0015] The valve body, the power source, the refrigerating member, and the heat exchanger are arranged in sequence;

[0016] Or, the valve body, the power source, the heat exchanger, and the refrigerating member are arranged in sequence;

[0017] Or, the valve body, the refrigerating member, the power source, and the heat exchanger are arranged in sequence;

[0021] In some embodiments of the present invention, a control valve is provided inside the valve body. The control valve is used to control the on-off states of the first valve port and the second valve port. When the temperature control device is in the exhaust state, the first valve port and the second valve port are communicatively connected. When the temperature control device is in the temperature control state, the first valve port and the second valve port are disconnected.

[0022] Compared with the prior art, the beneficial effects of the temperature control device in the present invention are as follows:

[0023] The present invention provides a temperature control device, which includes a liquid storage tank, a valve body, a power source, and a temperature control component. Among them, the liquid storage tank is internally provided with a circulating liquid. The liquid storage tank is communicated with the external atmosphere and is provided with a water inlet and an exhaust port. The valve body includes at least a first valve port and a second valve port. The first valve port is communicatively connected with the exhaust port, and the height where the exhaust port is located is higher than the height where the first valve port is located. The second valve port is communicatively connected with the water inlet, and the height where the first valve port is located is higher than the height where the second valve port is located. The valve body is communicatively connected with the power source and the temperature control component respectively. The power source is used to drive the circulating liquid to flow inside the temperature control device, and the temperature control component is used to export the heat of the circulating liquid. When the circulating liquid flows into the inner cavity of the valve body, the density of the air in the inner cavity of the valve body is greater than the density of the circulating liquid. Since the height where the exhaust port of the liquid storage tank is located is higher than the height where the first valve port is located, and the height where the first valve port of the valve body is located is higher than the height where the second valve port is located, the gas floats upward. The circulating liquid enters the valve body from the second valve port, and the gas in the valve body forms bubbles and moves from the first valve port to the inside of the liquid storage tank and is discharged to the external atmosphere. When the gas is exhausted, the circulating liquid in the liquid storage tank will apply pressure to the circulating liquid in the valve body, forming a pressure gradient. As the circulating liquid flows, the pressure gradient will gradually decrease along the exhaust pipe and the water inlet pipe until the circulating liquid reaches an equilibrium state, making the circulating liquid in the liquid storage tank unable to enter the valve body, realizing the automatic switch from external circulation to internal circulation. On the one hand, it can completely discharge the gas inside the temperature control device and improve the working stability of the temperature control device. On the other hand, it can switch from external circulation to internal circulation to ensure the working effect and accuracy of the temperature control device. Description of the Drawings

[0031] Please refer to Figure 1 and Figure 2, this application proposes a temperature control device 100, which includes a liquid storage tank 11, a valve body 13, a power source 12, and a temperature control component; wherein, the liquid storage tank 11 is internally provided with a circulating liquid, the liquid storage tank 11 is communicated with the external atmosphere, and the liquid storage tank 11 is provided with a water inlet 111 and an exhaust port 112; the valve body 13 at least includes a first valve port 131 and a second valve port 132, the first valve port 131 is communicated with the exhaust port 112 and the height where the exhaust port 112 is located is higher than the height where the first valve port 131 is located, the second valve port 132 is communicated with the water inlet 111, and the height where the first valve port 131 is located is higher than the height where the second valve port 132 is located; the valve body 13 is respectively communicated with the power source 12 and the temperature control component, the power source 12 is used to drive the circulating liquid to flow in the temperature control device 100, and the temperature control component is used to export the heat of the circulating liquid.

[0032] The power source 12 can be in the form of a centrifugal pump, a plunger pump, etc. The power source 12 is connected to the inner cavity of the valve body 13, and the power source 12 drives the circulating liquid to move from the liquid storage tank 11 into the inner cavity of the valve body 13. The power source 12 can be a centrifugal pump. The centrifugal pump includes components such as a pump casing, an impeller, a shaft, and a driving device. The centrifugal pump uses the centrifugal force generated by the rotating impeller to send out the circulating liquid. The circulating liquid is sucked in from the center of the pump and then pushed by the high-speed rotating impeller to the outlet of the pump. If air accumulates at the impeller, it will cause the impeller to rotate idly. The idling of the impeller will cause the temperature of the centrifugal pump to rise sharply and overload the circuit breaker, resulting in the machine stopping working.

[0033] To discharge the air inside the temperature control device 100, in this embodiment, the valve body 13 is provided with a first valve port 131 and a second valve port 132 connected to the liquid storage tank 11. When the circulating liquid flows into the inner cavity of the valve body 13, the density of the air in the inner cavity of the valve body 13 is greater than the density of the circulating liquid. Since the height where the exhaust port 112 of the liquid storage tank 11 is located is higher than the height where the first valve port 131 is located, the gas floats, and the gas forms bubbles and moves from the inner cavity of the valve body 13 to the inside of the liquid storage tank 11 and is discharged to the external atmosphere. The heights of the valve body 13 and the liquid storage tank 11 are the horizontal heights perpendicular to the ground. The height of the liquid storage tank 11 is higher than the height of the valve body 13, and the valve body 13 is arranged at the bottom of the liquid storage tank 11.

[0034] Since the height where the first valve port 131 of the valve body 13 is located is higher than the height where the second valve port 132 is located, the bubbles move from the first valve port 131 of the valve body 13 to the exhaust port 112. The inner cavity of the valve body 13 is also communicated with the temperature control component. The circulating liquid flows into the inside of the temperature control component. As the circulating liquid is continuously added, the air in the temperature control component and the inner cavity of the valve body 13 is squeezed by the circulating liquid to the first valve port 131, and then enters the liquid storage tank 11 through the exhaust port 112. The liquid storage tank 11 is communicated with the external atmosphere, and the bubbles formed by the air float up and enter the external atmosphere, realizing the discharge of the air inside the temperature control device 100.

[0035] Therefore, by setting valve openings at different heights, the separation of gas and water and the discharge of gas can be achieved, thereby improving the stability of the temperature control device 100 to ensure the working effect and accuracy of the temperature control device 100.

[0036] At the same time, through the synergistic action of the valve body 13, the power source 12 and the temperature control component, the temperature control device 100 realizes precise regulation and stable control of the temperature of the circulating liquid. The temperature control device 100 has a clear structure and distinct functions, and the connection between its components is tight, facilitating installation and maintenance. By effectively discharging the heat of the circulating liquid through the temperature control component, the stability and reliability of the temperature control system equipped with the temperature control device 100 are improved. Precise temperature control and stable heat discharge can effectively reduce energy consumption and improve energy utilization efficiency, meeting the development trend of energy conservation and environmental protection.

[0037] In one embodiment, the exhaust port 112 and the water inlet 111 are spaced apart and provided at the bottom of the liquid storage tank 11, and the exhaust port 112 and the water inlet 111 are at the same height. Both the water inlet 111 and the exhaust port 112 can pass through the circulating liquid. The arrangement of the two at the bottom of the liquid storage tank 11 can completely discharge the circulating liquid in the liquid storage tank 11, thereby effectively discharging air bubbles and ensuring the smooth flow of the circulating liquid. The design of the exhaust port 112 and the water inlet 111 at the same height can make it easier for air bubbles and the circulating liquid to separate during the exhaust process, improving the exhaust efficiency and thus enhancing the working effect and accuracy of the temperature control device 100.

[0038] In another embodiment, for the special structures of other components of the temperature control device 100, on the premise that the height of the exhaust port 112 is higher than that of the first valve port 131, the exhaust port 112 and the water inlet 111 can be provided on the side of the liquid storage tank 11, and the heights of the exhaust port 112 and the water inlet 111 may not be the same.

[0039] Furthermore, the temperature control device 100 further includes an exhaust pipe 114 provided between the exhaust port 112 and the first valve port 131, and the exhaust pipe 114 extends linearly along the height direction of the liquid storage tank 11 and the valve body 13. The linearly arranged exhaust pipe 114 has no bent part, avoiding the collision of air bubbles against the inner wall of the exhaust pipe 114 when passing through the bent part, which affects the discharge of air bubbles. At the same time, in terms of the spatial structure setting, the linearly arranged exhaust pipe 114 can effectively reduce the overall volume of the temperature control device 100 and improve the space utilization rate inside the temperature control device 100.

[0040] To enable the bubbles to pass through the exhaust pipe 114 smoothly, the temperature control device 100 further includes a water inlet pipe 113 provided between the water inlet 111 and the second valve port 132, and the length of the water inlet pipe 113 is greater than that of the exhaust pipe 114. The shorter length of the exhaust pipe 114 effectively reduces the distance for the gas to reach the exhaust port 112 from the first valve port 131, thereby increasing the gas discharge rate. The longer water inlet pipe 113 is set as a bent pipe to connect with the lower second valve port 132, ensuring that the circulating liquid can flow fully when entering the system and preventing air from entering the system to generate bubbles.

[0041] Through the settings of the exhaust pipe 114 and the water inlet pipe 113, the elimination of bubbles and the flow of the circulating liquid can be managed more effectively, thereby enhancing the working effect of the temperature control device 100 and the accuracy of temperature control. Overall, these design improvements will help improve the performance of the temperature control device 100 and provide a more reliable temperature control function.

[0042] In this embodiment, the first valve port 131 and the second valve port 132 are provided at opposite ends of the valve body 13. The opening direction of the first valve port 131 is set along the direction towards the liquid storage tank 11, and the opening directions of the first valve port 131 and the second valve port 132 are opposite. The technical effect of setting the first valve port 131 and the second valve port 132 at opposite ends and with opposite opening directions is to optimize the path of the liquid circulation flow, which helps to control the elimination of bubbles and the flow of the liquid more effectively. Since the opening direction of the second valve port 132 is opposite to that of the first valve port 131, the opening direction of the second valve port 132 faces away from the liquid storage tank 11, which helps the liquid to enter the power source 12 and the temperature control component from the liquid storage tank 11 and flow along the set path.

[0043] In other embodiments, on the premise that the height of the first valve port 131 is higher than that of the second valve port 132, the first valve port 131 and the second valve port 132 can be provided on the opposite end faces or adjacent end faces, and the opening directions of the first valve port 131 and the second valve port 132 are the same.

[0044] Further, the valve body 13 includes a third valve port 133 and a fourth valve port 134. One of the third valve port 133 is connected to the power source 12 or the temperature control component, and the fourth valve port 134 is connected to the other. The heights of the third valve port 133 and the fourth valve port 134 are both set between the heights of the first valve port 131 and the second valve port 132. The inner cavity of the valve body 13 can accumulate air and circulating liquid. The second valve port 132 is set at the lowest height position. The circulating liquid enters the inner cavity of the valve body 13 from the second valve port 132 and then enters the third valve port 133 and the fourth valve port 134, ensuring that the circulating liquid first squeezes out the gas in the inner cavity of the valve body 13 and then enters the power source 12 and the temperature control component, and the circulating liquid entering the power source 12 and the temperature control component does not carry air into the interior, improving the exhaust effect of the temperature control device 100.

[0045] Specifically, the heights of the third valve port 133 and the fourth valve port 134 are the same or different. If the heights of the third valve port 133 and the fourth valve port 134 are the same, the valve ports at the same height can make the liquid flow more evenly in the system to ensure that the liquid flows smoothly from the power source 12 or the temperature control component to the other part, improving the circulation efficiency and flow stability of the circulating liquid. The valve ports at the same height can also simplify the structure of the system, reduce the number of connecting pipes and components, and simplify the maintenance and operation process.

[0046] If the heights of the third valve port 133 and the fourth valve port 134 are different, the valve ports at different heights can control the flow direction of the liquid. By setting the third valve port 133 and the fourth valve port 134 at different positions, the circulating liquid can be guided to flow along a predetermined path to achieve specific temperature control or fluid regulation functions. The valve ports at different heights can increase the flexibility and adjustability of the system. According to needs, the positions of the third valve port 133 and the fourth valve port 134 can be adjusted to adapt to different operating requirements and fluid flow modes.

[0047] In this embodiment, the temperature control component includes a heat exchanger 14 and a refrigeration component 15. The heat exchanger 14 is used to exchange the heat of the circulating liquid, and the refrigeration component 15 is used to export the heat of the circulating liquid. The temperature control device 100 has an exhaust state and a temperature control state. When the temperature control device 100 is in the exhaust state, the circulating liquid flows from the second valve port 132 to the power source 12 and the temperature control component. The air in the temperature control device 100 moves from the first valve port 131 to the liquid storage tank 11. The liquid storage tank 11, the valve body 13, the power source 12, the refrigeration component 15, and the heat exchanger 14 are connected to form a closed exhaust circuit. When the temperature control device 100 is in the temperature control state, the air in the temperature control component is discharged, and the power source 12, the refrigeration component 15, the heat exchanger 14, and the valve body 13 are connected to form a closed temperature control circuit.

[0048] The switching between the exhaust state and the temperature control state of the temperature control device 100 is judged by the discharge of gas. Please refer to Figure 1When the circulating liquid in the liquid storage tank 11 first enters the valve body 13, the power source 12, the heat exchanger 14 and the refrigeration component 15, the temperature control device 100 is in the exhaust state, and the heat exchanger 14 and the refrigeration component 15 in the temperature control component do not work, saving energy.

[0049] Please refer to Figure 2 When the internal air of the valve body 13, the power source 12, the heat exchanger 14 and the refrigeration element 15 is exhausted, the temperature control device 100 is adjusted to the temperature control state. In the exhaust pipe 114 and the water inlet pipe 113, the position near the liquid storage tank 11 generates upper water pressure due to the gravity of the circulating liquid in the liquid storage tank 11. The upper circulating liquid will apply pressure to the lower circulating liquid, forming a pressure gradient. As the circulating liquid flows, the pressure gradient will gradually decrease along the exhaust pipe 114 and the water inlet pipe 113 until the water reaches a balanced state, so that the circulating liquid in the liquid storage tank 11 cannot enter the temperature control circuit through the exhaust pipe 114 and the water inlet pipe 113, realizing the internal closed cycle of the temperature control circuit, and the exhaust state and temperature control state of the temperature control device 100 can be automatically controlled.

[0050] Specifically, in the temperature control loop, along the flow direction of the circulating liquid: the valve body 13, the power source 12, the refrigeration component 15, and the heat exchanger 14 are arranged in sequence; or, the valve body 13, the power source 12, the heat exchanger 14 and the refrigeration component 15 are arranged in sequence; or, the valve body 13, the refrigeration component 15, the power source 12 and the heat exchanger 14 are arranged in sequence; or, the valve body 13, the refrigeration component 15, the heat exchanger 14 and the power source 12 are arranged in sequence; or, the valve body 13, the heat exchanger 14, the power source 12 and the refrigeration component 15 are arranged in sequence; or, the valve body 13, the heat exchanger 14, the refrigeration component 15 and the power source 12 are arranged in sequence.

[0051] The circulating fluid flows in the temperature control circuit through the power source 12. The refrigeration element 15 can be a water blanket, a water cap, etc. The refrigeration element 15 is used to be installed in the area where the patient needs to cool down. The heat exchanger 14 has a built-in compressor, which can support the fluid with lower heat by compressing the condensate. The circulating fluid with higher heat contacts the condensate with lower heat in the heat exchanger 14, and the heat of the circulating fluid is transferred to the condensate, and then transmitted to the refrigeration element 15 to cool the patient.

[0052] In one embodiment, a control valve is provided in the valve body 13, and the control valve is used to control the on-off state of the first valve port 131 and the second valve port 132. When the temperature control device 100 is in the exhaust state, the first valve port 131 is connected to the second valve port 132. When the temperature control device 100 is in the temperature control state, the first valve port 131 is disconnected from the second valve port 132. The control valve can be an electrical on-off valve such as a solenoid valve.

[0053] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
