[0052] See Figure 1 , Figure 1 is one of the principle block diagrams provided by the embodiments of this application, asFigure 1 As shown, the medical temperature controller includes: a water tank, a heating and cooling device, and a sheath that are sequentially arranged in a circulating water path;

[0053] The water tank is used to hold the treatment liquid, the heating and cooling device is used to heat or cool the treatment liquid, the outside of the sheath contacts the patient's treatment site, and the patient is physically treated by the heated or cooled treatment liquid inside the sheath;

[0054] Please refer to Figure 2 and Figure 3 , Figure 2 which is the second principle block diagram provided by an embodiment of the present application, Figure 3 and which is the third principle block diagram provided by an embodiment of the present application. As Figure 2 , Figure 3 shown, the medical temperature controller further includes a throttling branch and a control module. One end of the throttling branch is arranged on the inlet side of the water tank, and the other end of the throttling branch is arranged on the outlet side of the water tank. A first solenoid valve is arranged in the water path between the throttling branches in the circulating water path, and a second solenoid valve is arranged in the throttling branch; the control module is respectively connected to the first solenoid valve and the second solenoid valve, and the control module is used to control the opening and closing of the first solenoid valve and the second solenoid valve; when the first solenoid valve is opened, the second solenoid valve is closed; when the second solenoid valve is opened, the first solenoid valve is closed; the throttling branch is used to cut off the treatment liquid in the water tank, so as to only heat or cool the treatment liquid in the circulating water path.

[0055] Here, the water tank is used to hold the treatment liquid and is the starting point for the liquid storage and circulation of the entire temperature controller. The heating and cooling device heats or cools the treatment liquid in the water tank to meet different treatment requirements. The sheath, as a medium between the treatment liquid and the patient's treatment site, realizes heating or cooling treatment of the patient through the treatment liquid inside.

[0056] At the same time, introducing the throttling branch is an important improvement, which allows the treatment liquid in the water tank to be isolated from the treatment liquid in the circulating water path under specific circumstances, so as to only heat or cool the treatment liquid in the circulating water path.

[0057] The throttling branch is designed as an independent water path, with one end connected to the inlet side of the water tank and the other end connected to the outlet side of the water tank. The function of this branch is to be able to isolate the treatment liquid in the water tank from the treatment liquid in the circulating water path when needed, ensuring that the treatment liquid is independently heated or cooled in the circulating water path.

[0058] The first solenoid valve is located in the circulating water path, in the part between the intercepting branches. When the first solenoid valve is opened, the treatment liquid can flow freely between the water tank and the circulating water path. The second solenoid valve is located in the intercepting branch. When the second solenoid valve is opened, the intercepting branch is activated, isolating the treatment liquid in the water tank from the treatment liquid in the circulating water path.

[0059] The system adopts a mutually exclusive operation logic to ensure that the first solenoid valve and the second solenoid valve are not opened simultaneously. Specifically:

[0060] When the first solenoid valve is opened, the second solenoid valve is closed. At this time, the treatment liquid can flow freely between the water tank and the circulating water path for normal heating or cooling cycles. When the second solenoid valve is opened, the first solenoid valve is closed. At this time, the intercepting branch is activated, isolating the treatment liquid in the water tank from the treatment liquid in the circulating water path. In this way, the hot and cold therapy device will only heat or cool the treatment liquid in the circulating water path without affecting the treatment liquid in the water tank.

[0061] By isolating the treatment liquid in the water tank and only heating or cooling the treatment liquid in the circulating water path in the above manner, the target temperature can be reached faster, improving the treatment efficiency. When it is not necessary to heat or cool the treatment liquid in the entire water tank, energy can be saved by closing the first solenoid valve and opening the second solenoid valve. In this way, multiple sets of hot and cold therapy devices can be connected with only one water tank without being affected by the change of the water temperature in the water tank. In some cases, such as when replacing the treatment liquid or performing equipment maintenance, the treatment liquid in the water tank can be isolated from the treatment liquid in the circulating water path by activating the intercepting branch to avoid damaging the equipment. The design of the intercepting branch enables the system to quickly cut off the connection between the water tank and the circulating water path in some emergency situations to ensure the safety of the patient.

[0062] In some embodiments, the hot and cold therapy device includes: a power supply module, a refrigeration and heating module, a control module, and a water pump;

[0063] The power supply module is used to supply electrical energy to the hot and cold therapy device;

[0064] The refrigeration and heating module is used to raise or lower the temperature of the treatment liquid;

[0065] The water pump is used to provide kinetic energy for the treatment liquid in the circulating water path;

[0066] The control module is respectively connected to the refrigeration and heating module and the water pump.

[0067] Please continue to refer to Figure 3 as Figure 3As shown, the power supply module provides electrical energy for the cold and heat therapy device to ensure its normal operation. The refrigeration and heating module raises or lowers the temperature of the treatment liquid to meet different treatment requirements. The water pump provides kinetic energy for the treatment liquid in the circulating water path to ensure that the treatment liquid circulates in the system. The control module is connected to the refrigeration and heating module and the water pump and is responsible for controlling the operation of the entire cold and heat therapy device.

[0068] Through the coordinated work of the refrigeration and heating module and the control module, precise control of the temperature of the treatment liquid is achieved to ensure the treatment effect. The water pump provides kinetic energy for the treatment liquid to make it flow in the circulating water path, ensuring that the treatment liquid can act evenly on the patient's treatment site. The control module automatically adjusts the working states of the refrigeration and heating module and the water pump according to the preset parameters and the actual needs of the patient to ensure the comfort and safety of the treatment process.

[0069] In some embodiments, the cold and heat therapy device further includes: a pressure sensor;

[0070] The pressure sensor is disposed in the sheath, and the pressure sensor is used to detect the pressure of the treatment liquid in the sheath on the patient;

[0071] The signal output end of the pressure sensor is connected to the signal input end of the control module.

[0072] Here, adding the pressure sensor is an important improvement, which enhances the safety of the device and the comfort during the treatment process. Please continue to refer to Figure 3 , as Figure 3 shown, the pressure sensor is disposed in the sheath, in direct contact with the treatment liquid, and is used to detect the pressure of the treatment liquid in the sheath on the patient. The pressure sensor can monitor in real time the pressure of the treatment liquid on the patient in the sheath to ensure that the pressure is within a safe range. When the pressure exceeds the preset range, the pressure sensor will send a signal to notify the control module to make corresponding adjustments.

[0073] The signal output end of the pressure sensor is responsible for converting the detected pressure signal into an electrical signal. The signal output end of the pressure sensor is connected to the signal input end of the control module to ensure that the signal can be transmitted to the control module accurately and without error. After receiving the signal from the pressure sensor, the control module will perform real-time analysis and make corresponding adjustments according to the preset parameters.

[0074] The above method can monitor in real time the pressure of the treatment liquid on the patient to ensure the accuracy and safety of the treatment process. At the same time, the close cooperation between the pressure sensor and the control module can achieve automatic adjustment and optimization of the treatment process, improving the treatment effect and the patient experience.

[0075] In some embodiments, the circulating water path includes an internal water path and a treatment water path;

[0076] The internal waterway and the treatment waterway are in parallel. The on-off of the internal waterway is controlled by a third solenoid valve, and the on-off of the treatment waterway is controlled by a fourth solenoid valve.

[0077] The water pump is connected to the internal waterway and the treatment waterway respectively through a three-way valve.

[0078] The sheath is arranged in the treatment waterway.

[0079] The third solenoid valve and the fourth solenoid valve are respectively connected to the control module and are controlled by the control module to open and close.

[0080] Here, dividing the circulating waterway into an internal waterway and a treatment waterway is an important design improvement, which increases the flexibility and safety of the system. Please continue to refer to Figure 2 , such as Figure 2 shown, the circulating waterway is divided into two main parts: the internal waterway and the treatment waterway. These two waterways are in parallel, allowing the system to operate independently in different operating modes.

[0081] The internal waterway is mainly used for self-heating inside the system, or liquid circulation and testing. For example, self-heating can be carried out in advance when treating a patient, so that the patient can skip the process of warming up or cooling down, making the patient more comfortable, or for cleaning and testing during system maintenance.

[0082] The on-off of the internal waterway is controlled by a third solenoid valve, which is controlled by the control module to ensure opening or closing when the system requires it.

[0083] The treatment waterway is the part that directly contacts the patient. The treatment liquid circulates in the treatment waterway and acts on the patient's treatment site through the sheath.

[0084] The on-off of the treatment waterway is controlled by a fourth solenoid valve, also controlled by the control module. When the system is ready to treat the patient, this waterway will open to ensure that the treatment liquid can flow smoothly to the sheath.

[0085] The water pump is a key component in the circulating waterway. It is connected to the internal waterway and the treatment waterway through a three-way valve. This design allows the water pump to supply power to the two waterways simultaneously or separately, depending on the state of the solenoid valves and the instructions of the control module.

[0086] The sheath is arranged in the treatment waterway and directly contacts the treatment liquid. The treatment liquid acts on the patient's treatment site through the sheath to achieve the effect of heating or cooling.

[0087] Both the third solenoid valve and the fourth solenoid valve are connected to the control module, and the control module controls their opening and closing according to the state of the system and the treatment requirements.

[0088] It should be noted that in the embodiments of the present application, the first solenoid valve, the second solenoid valve, the third solenoid valve, and the fourth solenoid valve can be directly controlled by the control module, or can be controlled by the solenoid valve control module after being controlled by the control module, and then the solenoid valve control module controls the opening and closing.

[0089] In the above manner, by dividing the circulating water path into an internal water path and a treatment water path, the system can operate in multiple operation modes, increasing the flexibility of the system. The independent water path design can isolate problems by closing the corresponding solenoid valves when problems occur in the treatment water path, ensuring that other parts of the system can continue to operate normally and improving the safety of the system. The independent internal water path can be used for the maintenance and testing of the system, making the maintenance of the system more convenient and efficient. Through the precise control of the solenoid valves by the control module, the system can adjust the flow direction and flow rate of the treatment liquid in real time according to the treatment requirements, ensuring the efficiency and accuracy of the treatment process.

[0090] In some embodiments, there are multiple sets of the cold and heat therapy devices.

[0091] Here, in order to meet different treatment requirements or improve treatment efficiency, multiple sets of cold and heat therapy devices can be configured. For example, in the same ward, only one medical temperature controller can be used to treat patients in different beds.

[0092] In some embodiments, the cold and heat therapy device further includes: a first temperature sensor and a second temperature sensor;

[0093] The first temperature sensor is arranged in the circulating water path and is used to detect the temperature of the treatment liquid in the circulating water path;

[0094] The second temperature sensor is used to detect the body temperature of the patient;

[0095] The control module is further used to receive the temperature data of the first temperature sensor and the second temperature sensor, and control whether the cold and heat therapy device performs heating or cooling according to the temperature of the treatment liquid and the body temperature of the patient. Among them, when the absolute value of the difference between the temperature of the treatment liquid and the body temperature of the patient is less than or equal to the set value, heating or cooling is stopped; when the absolute value of the difference between the temperature of the treatment liquid and the body temperature of the patient is greater than the set value, heating or cooling is started.

[0096] Here, the introduction of the first temperature sensor and the second temperature sensor (in Figure 3 the first temperature sensor and the second temperature sensor are uniformly labeled as temperature sensors) is a key improvement. They are respectively used to monitor the temperature of the treatment liquid in the circulating water path and the body temperature of the patient, thereby ensuring that the treatment process is more accurate and safe.

[0097] The first temperature sensor is set in the circulating water path, in direct contact with the treatment fluid, and is used to monitor the temperature of the treatment fluid in real time. The first temperature sensor converts the detected temperature of the treatment fluid into electrical signals and transmits these signals to the control module.

[0098] The second temperature sensor is used to detect the body temperature of the patient, usually by being attached to the patient's skin. The second temperature sensor also converts the detected body temperature into electrical signals and transmits these signals to the control module.

[0099] The control module receives the temperature data from the first temperature sensor and the second temperature sensor. The control module calculates the difference between the temperature of the treatment fluid and the body temperature of the patient. When the absolute value of the difference between the temperature of the treatment fluid and the body temperature of the patient is less than or equal to the set value, the control module determines that the current temperature has met the treatment requirements, and thus stops the heating or cooling operation of the treatment fluid. When the absolute value of the difference between the temperature of the treatment fluid and the body temperature of the patient is greater than the set value, the control module starts the corresponding heating or cooling operation until the temperature difference meets the set requirements.

[0100] The above method can ensure a more accurate treatment process and thus improve the treatment effect by monitoring the temperatures of the treatment fluid and the patient in real time and adjusting the temperature accordingly. When the temperature of the treatment fluid is close to the body temperature of the patient, the control module will promptly stop the temperature adjustment to avoid adverse effects on the patient caused by overheating or overcooling. The system can automatically adjust according to the actual body temperature of the patient and the treatment requirements without manual intervention, improving the flexibility and convenience of the treatment. By precisely controlling the temperature adjustment, unnecessary energy waste can be avoided and the energy-saving performance of the system can be improved.

[0101] In some embodiments, the refrigeration and heating module is a thermoelectric refrigeration and heating module.

[0102] Here, in a medical temperature controller, the refrigeration and heating module is the core component for realizing temperature adjustment. The thermoelectric refrigeration and heating module works based on the thermoelectric effect (Seebeck effect and Peltier effect). When an electric current passes through a module composed of N-type and P-type semiconductor materials, a thermoelectric effect will occur, causing one side of the material to absorb heat and the other side to release heat. By changing the direction of the electric current, the functions of refrigeration or heating can be achieved.

[0103] The thermoelectric refrigeration and heating module includes: a hot end: which exchanges heat with the outside through a heat sink, absorbing heat from the environment (when refrigerating) or releasing heat (when heating).

[0104] A cold end: which contacts the object to be refrigerated or heated through a heat sink, transferring heat to the object to be refrigerated (when refrigerating) or absorbing heat from the object to be heated (when heating).

[0105] P-type semiconductor and N-type semiconductor: A large number of holes exist in the P-type semiconductor, while a large number of electrons exist in the N-type semiconductor. Under the action of an electric current, these two semiconductor materials can absorb and release heat.

[0106] In the embodiment of the present application, the semiconductor refrigeration and heating module includes a semiconductor, a copper block, a fan heat dissipation component, and a compressor module. The compressor module includes a compressor and a condenser. The semiconductor is in close contact with the copper block to lower or raise the temperature of the treatment liquid; the fan heat dissipation component is used to circulate and dissipate heat from the semiconductor, aiming to improve the refrigeration and heating rate.

[0107] In the embodiment of the present application, the refrigeration and heating module can also be a compression refrigeration module, an electric heating module, or a solid direct heating module. Compression refrigeration is a common and efficient refrigeration method. It uses a compressor to circulate the refrigerant, and realizes the transfer of heat through the phase change process of the refrigerant between the evaporator and the condenser, thereby achieving the refrigeration effect. Electric heating is to directly heat the treatment liquid through an electric current, or indirectly heat the treatment liquid through heating elements (such as electric heating wires, electric heating tubes, etc.). Solid direct heating uses a solid heating element (such as a PTC ceramic heater, etc.) to directly heat the treatment liquid.

[0108] In some embodiments, the medical temperature controller further includes: a liquid level sensor;

[0109] The liquid level sensor is used to detect the liquid level of the treatment liquid in the water tank, and the signal output end of the liquid level sensor is connected to the input end of the control module.

[0110] Here, the main function of the liquid level sensor is to monitor the liquid level of the treatment liquid in the water tank in real time, ensure that the treatment liquid is within an appropriate range, thereby ensuring the safety and effectiveness of the treatment process. By monitoring the liquid level of the treatment liquid in the water tank in real time, the liquid level sensor can ensure that the treatment liquid always remains within a safe range. If the liquid level is too low, it may cause insufficient treatment liquid and affect the treatment effect; if the liquid level is too high, it may cause overflow or other safety problems. Therefore, the liquid level sensor plays a crucial role in ensuring the safety of the treatment process.

[0111] Please continue to refer to Figure 2 and Figure 3, The liquid level sensor is connected to the control module and can automatically adjust the supply of the treatment liquid according to the change of the liquid level. For example, when the liquid level is lower than the preset value, the control module can start the automatic liquid replenishment program to ensure that the treatment liquid in the water tank is always sufficient. This automatic control function can not only improve the automation level of the treatment process, but also reduce the need for manual intervention, lower the operation difficulty and error rate. If the liquid level sensor detects an abnormal liquid level change (such as a sharp drop or rise in the liquid level), it can send a fault signal to the control module. After receiving these signals, the control module can trigger corresponding fault handling programs, such as sounding an alarm, stopping the treatment process, etc., to ensure the safety of the patient and the normal operation of the equipment.

[0112] In some embodiments, the medical temperature controller further includes: a display module;

[0113] The display module is connected to the control module, and the display module is used to display the current working state.

[0114] Here, the display module not only provides an interface for interaction with the operator, but also shows the working state and key parameters of the equipment in real time. Please continue to refer to Figure 3 , such as Figure 3 shown, the display module can visually show the current working state of the medical temperature controller. This includes key information such as the on / off state of the equipment, the cooling / heating mode, the temperature set value, the actual temperature, etc. When the equipment fails or an abnormal situation occurs, the display module can immediately display corresponding warning or prompt information. These information may include too low liquid level, too high temperature, equipment failure, etc., so that the operator can quickly take corresponding measures. For a medical temperature controller that requires specific operations or settings, the display module can also provide operation guidance or prompts to help the operator operate correctly.

[0115] The display module usually adopts a high-definition display screen, which can clearly show various information. The display module can show the working state and key parameters of the medical temperature controller in real time, ensuring that the operator can timely understand the operation situation of the equipment. The display module should provide a simple and clear operation interface and menu, which is convenient for the operator to perform various settings and operations. At the same time, it should also support multiple operation methods such as touch operation or button operation to meet the needs of different users.

[0116] The display module realizes the real-time transmission and display of information by connecting with the control module. The control module is responsible for collecting and processing various sensor data, and controlling the working state of the medical temperature controller according to these data. While the display module shows these data and state information to the operator in an intuitive way.
