Description

[0050] First Embodiment

[0051] refer to Figure 1 This application provides a hot and cold compress therapy system, including: a compression device 1, a first valve body structure 2, a first heat exchange device 3, a second heat exchange device 4, a second valve body structure 8, and an evaporator 5.

[0052] The compression device 1 is used to compress the fluid input into the device. The compression device 1 can be a compressor, and the fluid can be air. The compressor can compress the injected air to obtain high-temperature and high-pressure compressed air.

[0053] The first valve body structure 2 has a first port 201, a second port 202, a third port 203, and a fourth port 204. The first port 201 and the second port 202 are connected to form a first channel; the third port 203 and the fourth port 204 are connected to form a second channel. The first valve body structure 2 can be a four-way reversing valve. By switching the on and off of the first and second channels, the flow direction of compressed air can be controlled. This allows for flexible control of the compressed air flow, enabling the first treatment end 6 and the second treatment end 7 to perform cold or hot compress functions as needed. This improves the system's flexibility and adaptability, meeting the needs of different treatment scenarios and patients.

[0054] The first heat exchanger 3 and the second heat exchanger 4 are respectively used to connect to the corresponding first treatment end 6 and second treatment end 7. The first heat exchanger 3 and the second heat exchanger 4 obtain cold or heat through heat exchange with compressed air, and then transfer the heat or cold to the corresponding first treatment end 6 or second treatment end 7.

[0055] The second valve body structure 8 has a fifth port 801, a sixth port 802 and a seventh port 803; the fifth port 801 and the seventh port 803 can be connected to form a third channel; the sixth port 802 and the seventh port 803 can be connected to form a fourth channel; by switching the on and off of the third channel and the fourth channel, the flow direction of compressed air can be controlled.

[0056] The first port 201 and the third port 203 are connected to the outlet of the compressor, the second port 202 is connected to the first heat exchanger 3, the fourth port 204 is connected to the second heat exchanger 4, the second port 202 is also connected to the fifth port 801, and the fourth port 204 is connected to the sixth port 802; one end of the evaporator 5 is connected to the seventh port 803, and the other end is connected to the first heat exchanger 3 and the second heat exchanger 4 respectively.

[0057] The formation of the first channel and the second channel does not occur simultaneously, nor does the formation of the third channel and the fourth channel.

[0058] When end B needs to be used as the hot end and end A as the cold end, the first and third channels are connected, while the second and fourth channels are disconnected. The specific flow direction of the compressed air is as follows:

[0059] Air → Compression device 1 → First port 201 → Second port 202 → First compressed air → First heat exchange device 3 → Second heat exchange device 4 → Compression device 1;

[0060] Second compressed air → Fifth port 801 → Seventh port 803 → Evaporator 5 → merges with the first compressed air.

[0061] Throughout the process, the compressed air flowing out of the second port 202 splits into two paths. The first path of compressed air enters the first heat exchanger 3, where it exchanges heat with the first heat exchanger 3, allowing the first heat exchanger 3 to absorb heat and provide heat to the first treatment end 6. The second path of compressed air flows into the evaporator 5 through the third channel, thereby cooling the compressed air. The first path of compressed air after heat exchange and the second path of compressed air after cooling are combined and then enter the second heat exchanger 4 and flow back into the compression device 1, where they absorb heat from the second heat exchanger 4, thus cooling the second treatment end 7.

[0062] When end A needs to be used as the hot end and end B as the cold end, the second and fourth channels are connected, while the first and third channels are disconnected. The specific flow direction of the compressed air is as follows:

[0063] Air → Compression device 1 → Third port 203 → Fourth port 204 → First compressed air → Second heat exchange device 4 → Second heat exchange device 4 → Compression device 1;

[0064] Second compressed air → sixth port 802 → seventh port 803 → evaporator 5 → merges with the first compressed air.

[0065] Throughout the process, the compressed air flowing out of the third port 203 splits into two paths. The first path of compressed air enters the second heat exchanger 4, where it exchanges heat with the second heat exchanger 4, allowing the second heat exchanger 4 to absorb heat and provide heat to the second treatment end 7. The second path of compressed air flows into the evaporator 5 through the fourth channel, thereby cooling the compressed air. The first path of compressed air after heat exchange and the second path of compressed air after cooling are combined and then enter the first heat exchanger 3 and flow back into the compression device 1, where they absorb heat from the first heat exchanger 3, thus cooling the first treatment end 6.

[0066] In some embodiments, the first valve body structure 2 includes: a first body, a first valve core, and a first actuator mechanism. The first body has a first port 201, a second port 202, a third port 203, and a fourth port 204; a first flow channel is formed inside the first valve body and disposed inside the first body; the first valve core is position-switching, and in the first position state, the two ends of the first flow channel are respectively connected to the first port 201 and the second port 202; in the second position state, the two ends of the first flow channel are respectively connected to the third port 203 and the fourth port 204; the first actuator mechanism is connected to the first valve core and drives the first valve core to switch the first valve core between the first position state and the second position state.

[0067] The first valve body structure 2 can achieve two different channel connection methods. When the first valve core is in the first position, the first flow channel connects the first port 201 and the second port 202 to form the first channel; when in the second position, the first flow channel connects the third port 203 and the fourth port 204 to form the second channel. This allows the flow path of compressed air to be flexibly changed according to actual needs in the hot and cold compress therapy system, thus providing a basis for subsequent switching between hot and cold compress functions. For example, when the first treatment end 6 needs to be heated, the first valve core can be switched to the first position, allowing high-temperature and high-pressure compressed air to flow through the first channel to the first heat exchange device 3, thereby heating the first treatment end 6.

[0068] In some embodiments, the second valve body includes: a second body, a second valve core, and a second actuator. The second body has a fifth port 801, a sixth port 802, and a seventh port 803; a second flow channel is formed inside the second valve body and disposed inside the second body; the second valve core is position-switching, and in the third position state, the two ends of the second flow channel are connected to the fifth port 801 and the seventh port 803 respectively; in the fourth position state, the two ends of the second flow channel are connected to the sixth port 802 and the seventh port 803 respectively; the second actuator is connected to the second valve core and drives the second valve core to switch the second valve core between the third position state and the fourth position state.

[0069] The first valve body structure 2 is mainly responsible for controlling the distribution of compressed air through the relevant channels of the first treatment end 6 and the second treatment end 7, while the second valve body structure 8 further refines the control of the compressed air flow direction. By switching the second valve core between the third and fourth position states, it allows the compressed air to flow along different paths. Working in conjunction with the first valve body structure 2, it improves the control of the compressed air circulation path in the entire system, enabling the system to achieve more complex and flexible hot and cold compress modes.

[0070] In some embodiments, the first heat exchange device 3 includes: a first heat exchange chamber 301, a first heat exchanger 302, and a first pump 303. A first heat exchange fluid is disposed inside the first heat exchange chamber 301, and the first heat exchange chamber 301 is connected to the first treatment end 6. The first heat exchanger 302 is disposed inside the first heat exchange chamber 301 and is in contact with the first heat exchange fluid. The first heat exchanger 302, disposed inside the first heat exchange chamber 301 filled with the first heat exchange fluid, enables heat transfer. In the hot and cold compress therapy system, high-temperature, high-pressure compressed air output from the compressor 1 or low-temperature air cooled by the evaporator 5 exchanges heat with the first heat exchanger 302. In hot compress mode, the high-temperature air transfers heat to the first heat exchanger 302, which then transfers the heat to the first heat exchange fluid; in cold compress mode, the low-temperature air absorbs heat from the first heat exchange fluid.

[0071] A first pump body 303 is disposed in the passage between the first heat exchange chamber 301 and the first treatment end 6. The first pump body 303, installed in the passage between the first heat exchange chamber 301 and the first treatment end 6, can drive the first heat exchange fluid to circulate within the passage. After absorbing or releasing heat within the first heat exchange chamber 301, the first heat exchange fluid is transported to the first treatment end 6 by the action of the first pump body 303, thereby transferring cold or heat to the first treatment end 6 to achieve temperature regulation of the first treatment end 6.

[0072] In some embodiments, the system further includes a first expansion valve 9, which is disposed in the passage between the first heat exchange chamber 301 and the evaporator 5. The first expansion valve 9, disposed in the passage between the first heat exchange chamber 301 and the second heat exchange chamber 401, is capable of throttling and depressurizing the fluid.

[0073] In some embodiments, the second heat exchange device 4 includes: a second heat exchange chamber 401, a second heat exchanger 402, and a second pump body 403. The second heat exchange chamber 401 contains a second heat exchange fluid and is connected to the second treatment end 7. The second heat exchanger 402 is disposed inside the second heat exchange chamber 401 and is in contact with the second heat exchange fluid. The second heat exchanger 402 is located inside the second heat exchange chamber 401 filled with the second heat exchange fluid and is a key component for heat transfer. In the hot / cold compress therapy system, compressed air (high or low temperature) distributed from the first valve body structure 2 exchanges heat with the second heat exchanger 402. In a hot compress scenario, the heat from the high-temperature compressed air is transferred to the second heat exchanger 402, which then transfers the heat to the second heat exchange fluid. In a cold compress scenario, the low-temperature compressed air absorbs heat from the second heat exchange fluid, thus achieving the heat exchange process.

[0074] The second pump body 403 is disposed in the passage between the second heat exchange chamber 401 and the second treatment end 7. The second pump body 403 drives the second heat exchange fluid to circulate, ensuring that the second heat exchange fluid continuously circulates between the second heat exchange chamber 401 and the second treatment end 7. This circulation process helps maintain the uniformity of the temperature of the second heat exchange fluid, thereby ensuring that the temperature of each part of the second treatment end 7 is relatively consistent. In hot and cold compress therapy, uniform temperature distribution can improve the therapeutic effect and avoid discomfort to the patient caused by excessive local temperature differences.

[0075] In some embodiments, the system further includes a second expansion valve 10, which is disposed in the passage between the second heat exchange chamber 401 and the first heat exchange chamber 301. The second expansion valve 10, disposed in the passage between the second heat exchange chamber 401 and the first heat exchange chamber 301, is capable of throttling and depressurizing the fluid.

[0076] In some embodiments, the system further includes a fan 11, which is disposed on one side of the evaporator 5 and can accelerate the cooling of compressed air as it flows through the evaporator 5.

[0077] The general flow direction of compressed air is as follows:

[0078] When end B needs to be used as the hot end and end A as the cold end, the first and third channels are connected, while the second and fourth channels are disconnected. The specific flow direction of the compressed air is as follows:

[0079] Air → Compression device 1 → First port 201 → Second port 202 → First compressed air → First heat exchange box 301 → First heat exchanger 302 → First expansion valve 9 → Second expansion valve 10 → Second heat exchange box 401 → Second heat exchanger 402 → Compression device 1;

[0080] Second compressed air → Fifth port 801 → Seventh port 803 → Evaporator 5 → merges with the first compressed air.

[0081] When end A needs to be used as the hot end and end B as the cold end, the second and fourth channels are connected, while the first and third channels are disconnected. The specific flow direction of the compressed air is as follows:

[0082] Air → Compression device 1 → Third port 203 → Fourth port 204 → First compressed air → Second heat exchange box 401 → Second heat exchanger 402 → Second expansion valve 10 → First expansion valve 9 → Second heat exchange box 401 → Second heat exchanger 402 → Compression device 1.

[0083] Second compressed air → sixth port 802 → seventh port 803 → evaporator 5 → merges with the first compressed air.

[0084] Second Embodiment

[0086] The first treatment end 6 and the second treatment end 7 are thermally coupled together, and the thermal coupling relationship between the first heat exchange device 3 and the second heat exchange device 4 is matched. The temperatures of the first heat exchange device 3 and the second heat exchange device 4 are correlated, that is, the temperature difference between the two can be maintained within a certain range. Correspondingly, the temperature difference between the first treatment end 6 and the second treatment end 7 can also be controlled within a certain range, which can ensure the temperature stability of the first treatment end 6 and the second treatment end 7 and improve the treatment effect.
