Description

Technical Field

[0001] This invention relates to the technical field of medical rehabilitation equipment, specifically to a temperature-adjustable high-pressure oxygen-enriched cryotherapy. Background Technology

[0002] In the field of medical rehabilitation, efficient rehabilitation interventions are crucial for improving repair outcomes and shortening recovery periods in sports injury repair, postoperative rehabilitation, and chronic inflammation management. For common sports injuries such as muscle strains and ligament injuries among athletes and fitness enthusiasts, as well as wound healing and local inflammation control in postoperative patients, traditional interventions often employ cold compresses, medication, or hyperbaric oxygen therapy. Cryotherapy, by inhibiting local blood circulation in a low-temperature environment, reduces inflammation and edema, and relieves pain, and is widely used in the acute phase of sports injuries and postoperative inflammation control. However, existing cryotherapy equipment can cause local tissue vasoconstriction due to low temperatures, reducing blood oxygen perfusion. Long-term use may lead to tissue hypoxia, thus delaying tissue repair. Hyperbaric oxygen therapy, on the other hand, provides a hyperbaric oxygen environment, increasing blood oxygen partial pressure and tissue oxygen supply, providing sufficient oxygen for cell proliferation and promoting damaged tissue repair. However, existing hyperbaric oxygen equipment can only create a hyperbaric oxygen environment and cannot address the needs of low-temperature analgesia during the inflammatory phase and high oxygen supply during the repair phase, thus hindering further improvements in rehabilitation efficiency. Summary of the Invention

[0003] In view of this, the present invention provides a temperature-adjustable hyperbaric oxygen-enriched cryotherapy chamber to solve the problem that hyperbaric oxygen equipment can only create a hyperbaric oxygen environment and cannot meet the needs of low-temperature analgesia during the inflammatory phase and high-oxygen energy supply during the repair phase in the process of injury repair.

[0004] Firstly, this application provides a temperature-adjustable hyperbaric oxygen-enriched cryotherapy chamber, comprising: The cabin has a receiving cavity; An oxygen supply source is connected to the receiving cavity and is used to provide a first fluid medium with a preset oxygen concentration. A first heat exchanger, wherein the cold side flow channel of the first heat exchanger is connected to a cooling source, and the hot side flow channel of the first heat exchanger is connected to the receiving cavity, and the cooling source is used to provide a second fluid medium; The third fluid medium passes through the hot side channel of the first heat exchanger and exchanges heat with the second fluid medium in the cold side channel of the first heat exchanger before being transported to the receiving cavity. The cooling source includes a second heat exchanger (302), the inlet of the hot side flow channel of the second heat exchanger (302) is connected to the outlet of the cold side flow channel of the first heat exchanger (301) through a first compressor (303), and the inlet of the cold side flow channel of the first heat exchanger (301) is connected to the outlet of the hot side flow channel of the second heat exchanger (302) through a first throttling element (304).

[0005] The cooling source also includes a condenser (305), the outlet of the condenser (305) is connected to the inlet of the cold side flow channel of the second heat exchanger (302) through a second throttling element (306), the outlet of the cold side flow channel of the second heat exchanger (302) is connected to the inlet of the condenser (305) through a second compressor (307), and the condenser (305) contains a fourth fluid medium, the boiling point of the fourth fluid medium being higher than the boiling point of the second fluid medium; The piston movement frequency of the first compressor and the piston movement frequency of the second compressor are within a preset frequency range.

[0006] Beneficial Effects: The chamber provides a treatment space, where the oxygen source delivers a first fluid medium with a preset oxygen concentration to meet the oxygen demand for organ and tissue repair, thereby increasing cell proliferation and accelerating organ and tissue repair. A first heat exchanger facilitates heat exchange between the second and third fluid media delivered by the cold source. The third fluid medium, after heat exchange, enters the chamber and regulates the temperature, creating a low-temperature environment. This low-temperature environment inhibits inflammatory responses in organs and tissues by increasing anti-inflammatory interleukins and reducing the secretion of pro-inflammatory signaling molecules. It also reduces osteoclast production, promoting bone formation and reducing bone resorption. Furthermore, it effectively stimulates the parasympathetic nervous system, increasing lactate clearance. The low-temperature environment also reduces tissue metabolic oxygen consumption and the risk of oxidative stress. The chamber provides a closed space, preventing leakage of the first fluid medium and temperature loss during treatment, ensuring stable treatment parameters. The independent setup of the oxygen source and the first heat exchanger allows for separate adjustment of oxygen concentration and temperature, enabling adjustments to the temperature and oxygen concentration within the chamber according to the needs of different patients and treatment stages. The second fluid medium is a refrigerant. The first compressor can draw in the gaseous second fluid medium from the cold side flow channel of the first heat exchanger and compress it to increase its temperature and pressure. The compressed gaseous second fluid medium is then transported to the hot side flow channel of the second heat exchanger. The compressed gaseous second fluid medium releases heat in the second heat exchanger and transforms into a liquid second fluid medium. Since the first compressor continuously supplies the compressed gaseous second fluid medium to the hot side flow channel of the second heat exchanger, the liquid second fluid medium after heat exchange is pushed towards the first throttling element. After passing through the first throttling element, the pressure of the liquid second fluid medium decreases. The throttled liquid second fluid medium is then transported to the cold side flow channel of the first heat exchanger. After exchanging heat with the third fluid medium, the throttled liquid second fluid medium transforms into a gaseous second fluid medium. This cycle repeats continuously, achieving a continuous supply of cooling capacity to the receiving cavity. The fourth fluid medium is also a refrigerant. The condenser, in conjunction with the second compressor, the second throttling device, and the second heat exchanger, forms a two-stage heat exchange cycle. Furthermore, the fourth fluid medium has a higher boiling point than the second fluid medium, enabling it to carry away heat from the second fluid medium, thus improving overall heat exchange efficiency and allowing the second fluid medium to quickly reach the preset low temperature. The two-stage heat exchange cycle allows for wide-range temperature adjustment of the second fluid medium by regulating the parameters of the first compressor, the second compressor, the first throttling device, and the second throttling device, adapting to the differentiated low-temperature requirements of various rehabilitation scenarios. Simultaneously, multi-stage control reduces temperature fluctuations, resulting in higher temperature control precision and further optimizing the effects of hypothermia therapy.

[0007] In one alternative implementation, it further includes: A laminar flow element, in communication with the receiving cavity; The first pipe has one end connected to the hot side flow channel of the first heat exchanger and the other end connected to the laminar flow element. A first fan is disposed on the first pipe, and the first fan is used to transport the heat-exchanged third fluid medium to the laminar flow element.

[0008] Beneficial effects: The first pipeline provides a stable delivery channel for the third fluid medium after heat exchange; the first fan provides power for the delivery of the third fluid medium, improving the delivery efficiency of the medium and ensuring that the low-temperature medium is continuously and at a certain speed delivered to the laminar flow device; the laminar flow device can make the third fluid medium entering the containment cavity form a laminar flow state, avoiding local temperature unevenness caused by direct impact of the third fluid medium, keeping the temperature of each area in the chamber consistent, improving the uniformity and comfort of treatment, and further improving the therapeutic effect of low-temperature regulation.

[0009] In one alternative embodiment, the laminar flow element includes: The housing has an inlet connected to the first pipe and an outlet connected to the receiving cavity; A flow equalization membrane is located inside the chamber. The third fluid medium, after heat exchange, is sequentially transported to the receiving cavity after passing through the chamber inlet, the flow equalization membrane, and the chamber outlet.

[0010] Beneficial effects: The chamber guides and converges the third fluid medium after heat exchange, preventing diffusion during transport. The flow equalization membrane evens out the flow of the third fluid medium, allowing it to enter the chamber at a uniform flow rate and distribution, improving the uniformity of temperature distribution within the chamber and ensuring consistent treatment effects. The flow equalization membrane slows down the flow velocity of the medium, reducing the impact of airflow on the chamber environment and preventing discomfort to patients caused by direct airflow. Simultaneously, the stable flow of the medium reduces temperature fluctuations within the chamber, creating a more stable treatment environment and improving the patient's treatment experience.

[0011] In one optional embodiment, the oxygen source includes: A storage tank containing the first fluid medium with the preset oxygen concentration, and the storage tank being connected to the containment cavity via a second pipe; A cold trap having the cooling surface, a storage tank placed on the cooling surface, and a portion of the second fluid medium compressed by the first compressor being delivered to the second heat exchanger after exchanging heat with the cooling surface; A first flow control element is disposed on the second pipeline and is used to control the flow rate of a first fluid medium between the storage tank and the receiving cavity.

[0012] Beneficial effects: The storage tank can store a first fluid medium with a preset oxygen concentration, preventing interruption of oxygen supply during treatment; the first flow control component can regulate the flow rate of the first fluid medium delivered from the storage tank to the receiving cavity, allowing for flexible adjustment of oxygen supply according to patient needs, improving the targetedness and safety of treatment, and preventing excessively high or low oxygen concentrations from affecting treatment efficacy. The cold trap utilizes a portion of the second fluid medium compressed by the first compressor to cool the storage tank, eliminating the need for additional cooling equipment and achieving secondary utilization of cooling capacity; simultaneously, it ensures the temperature stability of the first fluid medium within the storage tank, preventing oxygen concentration fluctuations due to temperature changes and improving oxygen supply quality.

[0013] In one optional embodiment, the oxygen source further includes: An oxygen generator, wherein the oxygen generator is connected to a pressure pump via a third pipe, and the pressure pump is connected to the storage tank via a fourth pipe; The second flow control component is disposed on the third pipeline and is used to control the flow rate of oxygen between the oxygen generator and the booster pump. An air purifier, wherein the air purifier is connected to the booster pump via a fifth pipe; A third flow control component is disposed on the fifth pipe, and the third flow control component is used to control the air flow between the air purifier and the booster pump.

[0014] Beneficial effects: The oxygen concentrator can autonomously generate oxygen, which, combined with air purified by an air purifier, is mixed and pressurized by a booster pump and then delivered to the storage tank to prepare the first fluid medium. This eliminates the need for an external oxygen supply, enhancing the equipment's independence and applicability, making it suitable for scenarios without an external oxygen source. The second and third flow control components can respectively adjust the flow rates of oxygen output from the oxygen concentrator and air output from the air purifier. By adjusting their ratio, the oxygen concentration of the first fluid medium in the storage tank can be flexibly controlled, adapting to the differentiated oxygen concentration requirements of different treatment scenarios and improving the equipment's versatility. The air purifier removes impurities and pollutants from the air, preventing these impurities from mixing into the first fluid medium and being inhaled by the patient, or adhering to the inside of the chamber and affecting the equipment's lifespan. The oxygen concentrator and air purifier work together to ensure that the prepared first fluid medium is clean and sterile, preventing impurities from entering the chamber and affecting the patient's recovery or causing infection.

[0015] In one alternative implementation, it further includes: A first pressure relief valve is installed on the storage tank; A second pressure relief valve is installed on the cabin and is connected to the receiving cavity.

[0016] Beneficial effects: By installing a first pressure relief valve on the storage tank, the pressure inside the tank can be monitored in real time. When the pressure exceeds a preset safety threshold, the pressure will be automatically released, preventing safety accidents such as explosions and leaks caused by excessive pressure, thus ensuring the safety of the storage tank operation. A second pressure relief valve connected to the containment cavity on the chamber can be installed, which can monitor the pressure inside the containment cavity in real time. When the pressure inside the chamber is too high, the pressure will be automatically released, ensuring that the pressure inside the chamber is always within a safe range, preventing high pressure from harming the patient's body, while also ensuring the stability of the chamber structure, reducing the risk of equipment damage due to high pressure, and improving the safety and reliability of the entire equipment operation.

[0017] In one alternative implementation, it further includes: A first monitoring element is installed on the cabin body and is used to acquire the temperature inside the containment cavity. A second monitoring device is installed on the cabin body and is used to acquire the pressure inside the accommodating cavity. A third monitoring device is installed on the cabin body and is used to obtain the oxygen content in the containment cavity.

[0018] Beneficial effects: By installing a first, second, and third monitoring device on the chamber to acquire the temperature, pressure, and oxygen content within the cavity, changes in treatment parameters within the cavity can be monitored in real time. Medical staff can adjust the operation of the oxygen and cooling sources based on the monitoring data, thereby controlling the treatment parameters and ensuring that the treatment process remains within the preset optimal parameter range, improving the accuracy and effectiveness of the treatment. At the same time, real-time monitoring can promptly detect parameter abnormalities, preventing harm to patients due to excessive temperature, pressure, or oxygen content, further enhancing the safety of treatment and providing data support for the standardized management of the treatment process.

[0019] In one alternative implementation, it further includes: A sixth pipe, one end of which is connected to the first pipe and the other end of which is connected to the receiving cavity, and the output end of the sixth pipe and the output end of the second pipe are spaced apart; A second fan is disposed on the sixth pipe, and the second fan is used to transport the third fluid medium, which has undergone partial heat exchange in the first pipe, to the receiving cavity.

[0020] Beneficial effects: The sixth pipe forms an auxiliary delivery path for the third fluid medium, which, in conjunction with the original first pipe delivery path, allows the first fluid medium after heat exchange to diffuse more quickly within the chamber; the second fan can deliver part of the third fluid medium after heat exchange within the first pipe to the receiving cavity, enabling localized cryotherapy to other parts of the athlete's body; simultaneously, multi-path delivery can accelerate the rate at which the temperature and oxygen concentration within the chamber reach preset values, shortening pre-treatment preparation time and improving treatment efficiency; the flow rate of the auxiliary delivery medium can be flexibly controlled by adjusting the speed of the second fan, adapting to the parameter requirements of different areas within the chamber and enhancing control flexibility.

[0029] This application mainly employs a cabin, oxygen source, and heat exchanger working in synergy to achieve oxygen concentration and temperature regulation. This enables the cabin temperature and oxygen concentration to be adjusted according to different needs, promoting organ and tissue repair and inhibiting inflammation. The following is a further detailed description of this application.

[0030] The temperature-adjustable high-pressure oxygen-enriched cryotherapy chamber provided in this application embodiment, such as... Figure 1As shown, the device includes a chamber 101, an oxygen supply source, a first heat exchanger 301, and a third fluid medium. The chamber 101 has a cavity to provide a closed space for treatment, preventing leakage of the first fluid medium and temperature loss during treatment, and ensuring stable treatment parameters. The oxygen supply source is connected to the cavity and provides the first fluid medium with a preset oxygen concentration to meet the oxygen supply requirements for organ and tissue repair, increase cell proliferation rate, and accelerate organ and tissue repair. The cold side channel of the first heat exchanger 301 is connected to the cold supply source, and the hot side channel is connected to the cavity. The cold supply source provides a second fluid medium. The first heat exchanger 301 realizes heat exchange between the second fluid medium delivered by the cold supply source and the third fluid medium. The third fluid medium after heat exchange enters the cavity to regulate the temperature inside the chamber 101, creating a low-temperature environment. The low-temperature environment can inhibit the inflammatory response of organ and tissue by increasing the anti-inflammatory interleukin and reducing the secretion of pro-inflammatory signaling molecules. It can also reduce the production of osteoclasts, promote bone formation and reduce bone resorption. At the same time, it can effectively stimulate the parasympathetic nervous system, increase lactate clearance rate, reduce tissue metabolic oxygen consumption, and reduce the risk of oxidative stress.

[0031] Specifically, such as Figure 1 As shown, the chamber 101 is generally made of stainless steel, which has good strength and corrosion resistance. Its shape can be rectangular, and the internal cavity provides treatment space for the patient. The inner wall of chamber 101 can be lined with polyurethane or vacuum insulation panels to prevent heat exchange between the low temperature inside the chamber and the external environment. The front of chamber 101 is equipped with an unlockable, sealed glass door. The glass door is surrounded by an electrically operated, high-magnetic door catch. The magnetic force is slightly greater than the pressure of oxygen-enriched air, but it can be pushed open by a person, ensuring that personnel can exit the chamber smoothly in an emergency.

[0032] In this embodiment, the system further includes a laminar flow element 401, a first pipe 402, and a first fan 403. The laminar flow element 401 is connected to the receiving cavity. One end of the first pipe 402 is connected to the hot-side flow channel of the first heat exchanger 301, and the other end is connected to the laminar flow element 401. The first fan 403 is disposed on top and is used to transport the heat-exchanged third fluid medium to the laminar flow element 401. The first pipe 402 is a gas pipeline. The laminar flow element 401 includes a housing and a flow equalization membrane. The housing inlet is connected to the first pipe 402, and the housing outlet is connected to the receiving cavity. The flow equalization membrane is located inside the housing. The heat-exchanged third fluid medium is transported to the receiving cavity after passing through the housing inlet, the flow equalization membrane, and the housing outlet in sequence. The housing can be made of stainless steel, which has good strength and sealing performance. It can guide and converge the heat-exchanged third fluid medium, preventing the medium from diffusing during transportation. The flow equalization membrane, made of polymer, ceramic, or other composite materials, can equalize the flow of the third fluid medium, allowing it to enter the containment cavity at a uniform flow rate and distribution. This improves the uniformity of temperature distribution within the chamber 101, ensuring consistent treatment efficacy. The flow equalization membrane also slows down the flow velocity of the medium, reducing the impact of airflow on the environment inside the chamber 101 and preventing discomfort to the patient from direct airflow. Simultaneously, the stable flow of the medium reduces temperature fluctuations within the chamber, creating a more stable treatment environment and enhancing the patient's experience. The first conduit 402 is typically made of metal, offering good thermal conductivity and sealing, providing a stable delivery channel for the heat-exchanged third fluid medium. The first fan 403 can be an axial flow fan, providing power for the delivery of the third fluid medium, improving delivery efficiency, and ensuring the continuous and constant delivery of the cryogenic medium to the laminar flow element 401. The arrangement of the laminar flow element 401, the first pipe 402, and the first fan 403 allows the third fluid medium after heat exchange to enter the containment cavity more evenly, avoiding the problem of uneven local temperature caused by direct impact of the medium. This ensures that the temperature in each area of ​​the chamber 101 remains consistent, further improving the therapeutic effect of low-temperature regulation and the patient's treatment experience, and enhancing the practicality and comfort of the cryotherapy chamber.

[0033] In this embodiment, the cold-side flow channel of the first heat exchanger 301 is connected to a cooling source, and the hot-side flow channel of the first heat exchanger 301 is connected to a receiving cavity. The cooling source includes a second heat exchanger 302, a condenser 305, a first compressor 303, a first throttling element 304, a second compressor 307, and a second throttling element 306. The inlet of the hot-side flow channel of the second heat exchanger 302 is connected to the outlet of the cold-side flow channel of the first heat exchanger 301 through the first compressor 303, and the inlet of the cold-side flow channel of the first heat exchanger 301 is connected to the outlet of the hot-side flow channel of the second heat exchanger 302 through the first throttling element 304. The outlet of the condenser 305 is connected to the inlet of the cold-side flow channel of the second heat exchanger 302 through the second throttling element 306, and the outlet of the cold-side flow channel of the second heat exchanger 302 is connected to the inlet of the condenser 305 through the second compressor 307. The condenser 305 contains a fourth fluid medium, the boiling point of which is higher than that of the second fluid medium. The second fluid medium is refrigerant R290 with a boiling point of -42.17℃, and the fourth fluid medium can be R14 with a boiling point of -128℃. The first compressor 303 draws in the gaseous second fluid medium from the cold side channel of the first heat exchanger 301, compresses it, increasing its temperature and pressure, and then delivers it to the hot side channel of the second heat exchanger 302, where it releases heat and transforms into a liquid second fluid medium. As the first compressor 303 continuously delivers the compressed gaseous second fluid medium to the hot side channel of the second heat exchanger 302, the heat-exchanged liquid second fluid medium is pushed towards the first throttling element 304. After passing through the first throttling element 304, the pressure decreases, and the throttled liquid second fluid medium is delivered to the cold side channel of the first heat exchanger 301, where it exchanges heat with the third fluid medium and transforms into a gaseous second fluid medium. This cycle continues, continuously delivering cooling capacity to the receiving cavity. The condenser 305, in conjunction with the second compressor 307, the second throttling element 306, and the second heat exchanger 302, forms a two-stage heat exchange cycle. This cycle removes heat from the second fluid medium, improving overall heat exchange efficiency and enabling the second fluid medium to quickly reach the preset low temperature. The third fluid medium, typically air, flows through the hot-side channel of the first heat exchanger 301 and exchanges heat with the second fluid medium in the cold-side channel of the first heat exchanger 301 before being transported to the receiving cavity. Both the first compressor 303 and the second compressor 307 are oil-free linear compressors. The piston stroke within the compressor is 0-100 mm, and the piston movement frequency is 20-200 Hz. By adjusting the piston stroke and movement frequency, different cooling capacities can be supplied. The temperature accuracy of this cooling source is ±0.5℃.

[0034] like Figure 1As shown, the oxygen supply source includes a storage tank 201, a cold trap 203, a first flow control element 204, an oxygen generator 205, a second flow control element 209, an air purifier 210, a third flow control element 212, and a fourth flow control element 505. The storage tank 201 is a high-pressure gas cylinder, such as a Dewar gas cylinder, used to store a first fluid medium with a preset oxygen concentration to prevent oxygen supply interruption during treatment. The storage tank 201 is connected to the receiving cavity via a second pipe 202. A first flow control element 204 is installed on the second pipe 202, which is a gas pipeline. The first flow control element 204 can be a precision flow regulating valve with an adjustment accuracy of 0.1L. The first flow control element 204 is used to control the flow rate of the first fluid medium between the storage tank 201 and the receiving cavity. The cold trap 203 has a cooling surface, on which the storage tank 201 is placed. The cold trap 203 is made of copper and is an open rectangular box. The exterior of the cold trap 203 is wrapped with insulation cotton, and the interior contains low-temperature refrigeration oil. Part of the storage tank is immersed in the refrigeration oil. The cooling surface is the surface of the storage tank 201 covered by the refrigeration oil. Both the first throttling element 304 and the second throttling element 306 are expansion valves. After being throttled by the first throttling element 304, a portion of the second fluid medium passes through the fourth flow control element 505, exchanges heat with the refrigeration oil, and is then delivered to the first compressor 303 to ensure the refrigeration oil reaches a preset temperature. The remaining portion of the second fluid medium is delivered to the first heat exchanger. The fourth flow control element is a solenoid valve. The cold trap 203 enables the secondary utilization of cooling capacity and ensures the temperature stability of the first fluid medium in the storage tank 201, preventing oxygen concentration fluctuations due to temperature changes. Oxygen concentrator 205 serves as an oxygen-generating device. Oxygen concentrator 205 employs a molecular sieve design, outputting oxygen at a concentration of 90%-95%. Air purifier 210 utilizes physical filtration to remove dust from the air, ensuring clean air delivery. Oxygen concentrator 205 is connected to booster pump 207 via a third pipe 206, which is also a gas path pipe. Air purifier 210 is also connected to booster pump 207 via a fifth pipe 211. Booster pump 207 is connected to storage tank 201 via a fourth pipe 208. Both fourth pipe 208 and fifth pipe 211 are gas path pipes. A second flow control component 209, which can be a flow regulating valve with an adjustment accuracy of 0.1L, is installed on the third pipeline 206 to control the oxygen flow rate between the oxygen generator 205 and the booster pump 207. A third flow control component 212, which can also be a flow regulating valve with an adjustment accuracy of 0.1L, is installed on the fifth pipeline 211 to control the air flow rate between the air purifier 210 and the booster pump 207. By adjusting the opening of these two flow control components, the oxygen concentration of the first fluid medium in the storage tank 201 can be flexibly controlled.The oxygen supply source, through components such as an oxygen generator 205, an air purifier 210, a booster pump 207, and a storage tank 201, prepares and stores a first fluid medium with a preset oxygen concentration. This fluid medium is then delivered to the receiving cavity via a first flow control component 204 to meet the patient's oxygen supply needs. The cooling source, through a circulation system consisting of a first compressor 303, a second compressor 307, a first throttling device 304, a second throttling device 306, a second heat exchanger 302, and a condenser 305, provides cooling to the first heat exchanger 301. The first heat exchanger 301 facilitates heat exchange between the second and third fluid media. The cooled third fluid medium then enters the receiving cavity to regulate its temperature. This structural design allows for separate regulation of oxygen concentration and temperature, enabling adjustments to the temperature and oxygen concentration within the receiving cavity according to the needs of different patients and different treatment stages. This effectively promotes organ and tissue repair, inhibits inflammatory responses, and solves the problem of incompatibility between cryotherapy and hyperbaric oxygen therapy in existing technologies, thus improving treatment efficacy and safety.

[0035] In this embodiment, as Figure 1 As shown, the system also includes a first pressure relief valve 501 and a second pressure relief valve 502. The first pressure relief valve 501 is installed on the storage tank 201 and can monitor the pressure inside the storage tank 201 in real time. When the pressure exceeds a preset safety threshold, it automatically relieves pressure to prevent safety accidents such as explosions or leaks caused by excessive pressure in the storage tank 201, thus ensuring the safe operation of the storage tank 201. The second pressure relief valve 502 is installed on the chamber 101 and is connected to the receiving cavity. It can monitor the pressure inside the receiving cavity in real time and automatically relieves pressure when the pressure inside the chamber is too high, ensuring that the pressure inside the chamber is always within a safe range, preventing high pressure from harming the patient's body, while also ensuring the stability of the structure of the chamber 101, reducing the risk of equipment damage due to high pressure, and improving the safety and reliability of the entire equipment operation. Both the first pressure relief valve 501 and the second pressure relief valve 502 are automatic pressure relief valves. The first pressure relief valve 501 automatically relieves pressure when the pressure exceeds 10 atm (atmospheric pressure), and the second pressure relief valve 502 automatically relieves pressure when the pressure exceeds 3 atm. After the cryotherapy was completed, the chamber 101 was depressurized to standard atmospheric pressure.

[0036] In this embodiment, as Figure 1As shown, the system also includes a monitoring module 503, which comprises a first monitoring element, a second monitoring element, a third monitoring element, and a control unit. The first monitoring element is installed on the chamber 101 to acquire the temperature inside the cavity; the second monitoring element is installed on the chamber 101 to acquire the pressure inside the cavity; and the third monitoring element is installed on the chamber 101 to acquire the oxygen content inside the cavity. Through these three monitoring elements, medical personnel can obtain real-time information on changes in treatment parameters within the cavity and adjust the operation of the oxygen and cooling sources accordingly. This allows for the control of treatment parameters, ensuring that the treatment process remains within the preset optimal parameter range, improving the accuracy and effectiveness of the treatment. Simultaneously, real-time monitoring can promptly detect parameter abnormalities, preventing harm to patients due to excessive temperature, pressure, or oxygen content, further enhancing treatment safety and providing data support for the standardized management of the treatment process. The first monitoring element is a temperature sensor with a range of -200 to 200℃ and an accuracy of ±0.1℃. This temperature value controls the stroke and frequency of the first compressor 303 and the second compressor 307. The second monitoring element is a pressure sensor with a range of 0 to 5 atm and an accuracy of ±0.01 atm. The pressure measurement adjusts the opening of the first flow control element 204. The third monitoring element is an oxygen content sensor with a range of 0 to 100% and an accuracy of ±1%. The oxygen content measurement controls the opening of the second and third control elements. The control unit uses a PLC controller, a microcontroller, or other microcontrollers. The control unit is electrically connected to the first compressor 303, the second compressor 307, the first flow control element 204, the second flow control element 209, the third flow control element 212, and the first, second, and third monitoring elements via cables or wireless communication. The control unit is also electrically connected to an emergency stop button 504, which is installed on the outer wall of the cabin 101. The emergency stop button 504 is used to open the cabin 101 door, pause the operation of the first compressor 303 and the second compressor 307, and shut down the first flow controller 204, the second flow controller 209, and the third flow controller 212. The emergency stop button 504 is an illuminated button.

[0037] In this embodiment, as Figure 1As shown, the system also includes a sixth pipe and a second fan 601. One end of the sixth pipe is connected to the first pipe 402, and the other end is connected to the receiving cavity. The sixth pipe is also a gas pipeline, and its output end is spaced apart from the output end of the second pipe 202. The second fan 601 is mounted on the sixth pipe and is used to transport the partially heat-exchanged third fluid medium in the first pipe 402 to the receiving cavity. The sixth pipe forms an auxiliary transport path for the third fluid medium, which, in conjunction with the original transport path of the first pipe 402, allows the heat-exchanged first fluid medium to diffuse more quickly within the chamber. The second fan 601 can provide localized cryotherapy to other parts of the athlete's body. Simultaneously, multi-path transport can accelerate the rate at which the temperature and oxygen concentration within the chamber reach preset values, shortening pre-treatment preparation time and improving treatment efficiency. Furthermore, the flow rate of the auxiliary transported medium can be flexibly controlled by adjusting the speed of the second fan 601, adapting to the parameter requirements of different areas within the chamber and improving control flexibility. The first pressure relief valve 501 and the second pressure relief valve 502 ensure the safe operation of the equipment and prevent safety accidents caused by excessive pressure. The first, second, and third monitoring devices enable real-time monitoring of the temperature, pressure, and oxygen content within the chamber, facilitating adjustments to treatment parameters by medical staff based on the monitoring data and improving the accuracy and safety of treatment. The sixth conduit and the second fan 601 accelerate the adjustment of temperature and oxygen concentration within the chamber, enabling localized cryotherapy, improving treatment efficiency and control flexibility, and allowing the cryotherapy chamber to better meet the needs of different patients and different treatment stages.
