[0017] A micro-hyperbaric oxygen chamber is a health device that allows users to absorb pure or high-concentration oxygen at a pressure exceeding one atmosphere (1.0 ATA). It currently has broad application prospects and clinical value in the field of physical and mental rehabilitation. By providing a slightly high-pressure environment, the micro-hyperbaric oxygen chamber allows more oxygen to dissolve in the blood, delivering more oxygen to various tissues and organs throughout the body, thereby improving physical condition, promoting metabolism, and accelerating the repair of cell damage.

[0018] According to one embodiment of the present invention, micro-hyperbaric oxygen can help slow down the shortening of telomeres at the ends of chromosomes in the blood cells of healthy elderly people, thereby reducing the aggregation of senescent cells in the body, and has anti-aging or life-extending functions. Hyperbaric oxygen can relieve and treat poisoning by harmful gases such as coal gas, hydrogen sulfide, and biogas, and promote recovery from diseases such as cerebral thrombosis, cerebral hemorrhage, brain trauma, neuritis, vasculitis, diabetic gangrene, difficult-to-heal ulcers, fetal maldevelopment, neonatal asphyxia, acute gas embolism, decompression sickness, altitude sickness, sudden deafness, Meniere's syndrome, and vertigo.

[0019] For example, the air pressure in the hyperbaric oxygen chamber can be selected to be 2-3 ATA, and the inhaled oxygen concentration can be selected to be 85% to 99%.

[0020] In the process of realizing the concept of the present invention, the inventors found that the relevant technology has at least the following problems: during the operation of the micro-hyperbaric oxygen chamber, since the internal pressure of the oxygen chamber is higher than the external atmospheric pressure, the cabin walls and doors of the oxygen chamber are under unidirectional alternating pressure shock for a long time, which can easily cause problems such as air leakage in the oxygen chamber and material deformation, and even cause safety risks such as explosion.

[0021] The inventors discovered that if the impact pressure exceeds the yield strength of the bulkhead and door materials, it can cause permanent damage to them and even lead to safety risks such as explosions. Therefore, monitoring the impact pressure of the various materials in the oxygen chamber is essential. Furthermore, repeated impacts can loosen the bolts securing the chamber and door, potentially causing air leaks. This can make it difficult to achieve the required internal pressure or cause the compressor to start and stop repeatedly. Therefore, monitoring the bolts is also essential.

[0022] In order to at least partially solve the technical problems existing in the related art, the present invention proposes a micro-hyperbaric oxygen chamber system based on safety monitoring, which includes a treatment cabin body, a bolt monitoring device, a deformation monitoring device and a control device, wherein: the treatment cabin body includes a closed accommodation space for accommodating a user, and at least one wall panel for defining the accommodation space, a treatment environment based on a target oxygen concentration and a target air pressure can be formed in the accommodation space, and at least one wall panel is connected by multiple bolts; the bolt monitoring device is used to monitor the preload state of at least one bolt; the deformation monitoring device is used to monitor the deformation state of at least one wall panel; the control device is used to regulate the treatment environment in the accommodation space according to the preload state of at least one bolt, and / or according to the deformation state of at least one wall panel.

[0023] Figure 1 A micro-hyperbaric oxygen chamber system based on safety monitoring according to an embodiment of the present invention is shown.

[0024] like Figure 1 As shown, the micro-hyperbaric oxygen chamber system 100 based on safety monitoring includes a treatment chamber 110, a bolt monitoring device 120, a deformation monitoring device 130 and a control device 140. The treatment chamber 110 includes an enclosed accommodation space for accommodating a user and at least one wall panel for defining the accommodation space.

[0025] As an example, the treatment cabin may be substantially in the shape of a cube. For example, the treatment cabin may include a top wall panel, a bottom wall panel, a first side wall panel, a second side wall panel, a third side wall panel, and a fourth side wall panel, wherein adjacent wall panels are fixedly connected by a plurality of bolts.

[0026] For example, the top wall panel, bottom wall panel, first side wall panel, second side wall panel, third side wall panel, and fourth side wall panel define an enclosed accommodation space for accommodating a user. Within the accommodation space, a therapeutic environment based on a target oxygen concentration and a target air pressure can be formed. The target oxygen concentration can be, for example, in the range of 85% to 99%, and the target air pressure can be, for example, in the range of 2-3 ATA.

[0027] According to an embodiment of the present invention, a bolt monitoring device is used to monitor the preload state of at least one bolt. In one example, at least one bolt to be monitored can be selected from a plurality of bolts used to secure a wall panel, and the bolt monitoring device can be used to monitor the preload state of the at least one bolt to be monitored. For example, those skilled in the art can reasonably select bolts to be monitored based on actual needs or application scenarios. For example, bolts at the edges of wall panels that bear greater pressure, bolts at vulnerable locations of the treatment cabin, etc., are selected, and no specific limitations are given here.

[0028] As an example, for each bolt to be monitored, the bolt monitoring device can detect the preload force at a first preset frequency and feed the detected preload force back to the control device, thereby enabling real-time monitoring of the preload force status of at least one bolt to be monitored. The first preset frequency can be, for example, every 5 seconds, without limitation.

[0029] According to an embodiment of the present invention, a deformation monitoring device is used to monitor the deformation state of at least one wall panel. In one example, at least one wall panel to be monitored that is subjected to a large alternating pressure shock can be selected from the at least one wall panel of the treatment cabin, and the deformation monitoring device can be used to monitor the deformation state of the at least one wall panel to be monitored. For example, those skilled in the art can reasonably select the wall panels to be monitored based on actual needs or application scenarios, such as the first side wall panel, the second side wall panel, the third side wall panel, and the fourth side wall panel, without specific limitation herein.

[0030] As an example, for each monitored wall panel, the deformation monitoring device can detect its deformation degree at a second preset frequency and feed the detected deformation degree back to the control device, thereby enabling real-time monitoring of the deformation state of at least one monitored wall panel. The second preset frequency can be, for example, once every 5 seconds, without limitation.

[0031] According to an embodiment of the present invention, the control device is used to regulate the treatment environment in the accommodation space according to the preload state of at least one bolt and / or the deformation state of at least one wall panel.

[0032] For example, the control device can be used to regulate the treatment environment within the accommodation space based on the preload state of at least one bolt to be monitored. For example, the control device can be used to regulate the treatment environment within the accommodation space based on the deformation state of at least one wall panel to be monitored. For example, the control device can be used to regulate the treatment environment within the accommodation space based on the preload state of at least one bolt to be monitored and the deformation state of at least one wall panel to be monitored.

[0033] Exemplarily, the control device regulating the treatment environment in the accommodation space may include at least one of the following: regulating the oxygen concentration environment, regulating the air pressure environment, and stopping the operation of the treatment cabin.

[0034] According to one embodiment of the present invention, Figure 1 As shown, the control device 140 can be arranged outside the treatment cabin 110, and the bolt monitoring device 120 and the deformation monitoring device 130 can be arranged inside the treatment cabin 110, and the bolt monitoring device 120 and the deformation monitoring device 130 are respectively connected to the control device 140.

[0035] For example, with respect to specific implementations, the control device can be implemented using various suitable methods. Those skilled in the art will implement this in a reasonable manner based on actual needs or application scenarios, and this is not a limitation. For example, the control device can be implemented using a general-purpose processor ("CPU"), a dedicated processor (such as a graphics processing unit, "GPU"), or a combination of the two. In some scenarios, the control device can also be implemented using a programmable logic controller ("PLC").

[0036] According to an embodiment of the present invention, by utilizing a bolt monitoring device to perform real-time monitoring of the preload state of at least one bolt to be monitored, and by utilizing a deformation monitoring device to perform real-time monitoring of the deformation state of at least one wall panel to be monitored, the control device can timely detect potential safety hazards, such as loose bolts or wall panel deformation, based on the preload state of at least one bolt to be monitored and / or the deformation state of at least one wall panel to be monitored, and then can perform targeted regulation of the treatment environment in the accommodation space to ensure that the treatment environment in the accommodation space is stable within a safe range and avoid the occurrence of safety accidents, thereby effectively improving the safety and reliability of the operation of the micro-hyperbaric oxygen chamber and providing users with a comfortable, safe, reliable and effective micro-hyperbaric oxygen therapy environment.

[0037] According to an embodiment of the present invention, a plurality of connecting holes with internal threads are provided on the periphery of each wall panel, and each bolt includes a cap and a rod connected to the cap, wherein the rod is provided with external threads and matches with the connecting holes on the periphery of the wall panel.

[0038] According to an embodiment of the present invention, the bolt monitoring device may include at least one ultrasonic probe, a first signal processing unit, and a first signal transmission unit.

[0039] According to one embodiment of the present invention, at least one ultrasonic probe corresponds to at least one bolt to be monitored. For each bolt to be monitored, the ultrasonic probe can be positioned on the cap of the bolt, with the detection end of the ultrasonic probe parallel to the bolt's shaft. The ultrasonic probe is used to determine the change in the bolt's mating length based on the ultrasonic signal.

[0040] For example, the ultrasonic probe can be a transceiver-integrated ultrasonic probe, with the ultrasonic detection end facing the wall panel opposite the cap. For example, the ultrasonic probe can transmit ultrasonic waves toward the wall panel and process the received ultrasonic waves to calculate the distance between the cap and the wall panel based on the ultrasonic wave transmission and reception time difference and propagation speed, thereby determining the change in the mating length of the rod. For example, the ultrasonic probe can transmit the change in the mating length of the rod to the first signal processing unit.

[0041] According to an embodiment of the present invention, the first signal processing unit is configured to determine the pre-tightening force of the bolt based on the variation in the fitting length, and transmit a first signal representing the pre-tightening force to the first signal transmission unit.

[0042] For example, the first signal processing unit receives the change in the fitting length of the rod from the ultrasonic probe, can determine the preload force of the bolt based on the change in the fitting length of the rod, and transmits the first signal representing the preload force and the probe identifier to the first signal transmission unit.

[0043] Illustratively, the first signal processing unit may include a first microcontroller unit. For example, the first microcontroller unit may be implemented by a programmable logic controller (PLC), a microcontroller unit (MCU), or the like, without limitation herein.

[0044] The first signal transmission unit is used to transmit the first signal and a bolt identifier representing the bolt to the control device, wherein the bolt identifier is determined based on a probe identifier of the ultrasonic probe.

[0045] Exemplarily, the first signal transmission unit may include an RFID chip and a bolt monitoring gateway. For example, the RFID chip may transmit a first signal representing the preload force to the bolt monitoring gateway based on radio frequency identification technology. For example, the bolt monitoring gateway may include an RFID card reader and a serial port transmission subunit. The RFID card reader may read the first signal and transmit the first signal and the bolt identification to the control device via the serial port transmission subunit. The bolt identification is determined based on the probe identification of the ultrasonic probe.

[0046] Figure 2 A bolt monitoring device according to an embodiment of the present invention is shown.

[0047] In one example, if Figure 2 As shown, the bolt monitoring device 120 may include at least one ultrasonic probe 121, a first microcontroller unit 122, a first RFID chip 123, and a bolt monitoring gateway 124. At least one ultrasonic probe 121 corresponds to at least one bolt to be monitored. The ultrasonic probe 121 is located on the cap of the bolt to be monitored, with the detection end of the ultrasonic probe 121 parallel to the shaft of the bolt to be monitored. The at least one ultrasonic probe 121 is connected to each of the first microcontroller units 122, which are connected to the first RFID chip 123, which is in communication with the bolt monitoring gateway 124.

[0048] According to an embodiment of the invention, the at least one panel comprises a hatch and at least one bulkhead.

[0049] In one example, the at least one wall panel to be monitored may include, for example, a first side wall panel, a second side wall panel, a third side wall panel, and a fourth side wall panel, and a hatch provided on the first side wall panel.

[0050] According to an embodiment of the present invention, the deformation monitoring device may include a plurality of flexible pressure sensors, a second signal processing unit, and a second signal transmission unit.

[0051] According to one embodiment of the present invention, a plurality of flexible pressure sensors may be respectively arranged at the easily deformable locations of the hatch, the first side wall panel, the second side wall panel, the third side wall panel and the fourth side wall panel.

[0052] For example, during operation of the micro-hyperbaric oxygen chamber, each panel will tend to expand outward due to the higher pressure inside the chamber than outside. This creates tensile stress at the center of the panel due to the pressure differential. Furthermore, because the panel edges are bolted together, expansion at the center is limited by the edge fixing points, generating bending stress at the center of the panel due to the edge fixings. Due to the complex stress state at the center of the panel, these stresses may cause deformation or damage at the center of the panel. Therefore, flexible pressure sensors are preferably located at the center of each of the door, first side panel, second side panel, third side panel, and fourth side panel.

[0053] According to an embodiment of the present invention, a flexible pressure sensor can be used to detect pressure at a deformable area and output a voltage signal to a second signal processing unit. For example, a flexible pressure sensor is a sensor made of flexible material that can sense force by directly detecting surface deformation. Compared to traditional silicon-based MEMS pressure sensors, this type of sensor has greater adaptability and a wider range of applications.

[0054] For example, a flexible pressure sensor can consist of two layers of flexible electrodes and a functional soft material in between. When external pressure acts on the sensor, the functional soft material in between deforms, causing a change in the distance or contact area between the two layers of flexible electrodes, which in turn causes a change in capacitance or resistance. By measuring these changes, the magnitude and distribution of pressure can be detected. For example, the flexible pressure sensor can be a bridge-type piezoelectric sensor.

[0055] According to an embodiment of the present invention, the second signal processing unit is used to determine the target pressure of the easily deformable part based on the voltage signal and the predicted pressure related to the change in the fitting length of at least one bolt, and transmit the second signal representing the target pressure to the second signal transmission unit, wherein the target pressure is used to represent the degree of deformation of the easily deformable part.

[0056] Exemplarily, the second signal processing unit may include an amplifying and filtering circuit, an analog-to-digital conversion circuit, and a second microcontroller unit. For example, the amplifying and filtering circuit may be configured to increase the input impedance and the voltage signal output by the flexible pressure sensor, and transmit the processed voltage signal to the analog-to-digital conversion circuit. For example, the analog-to-digital conversion circuit may be configured to convert the voltage signal from the amplifying and filtering circuit into a digital voltage signal, and transmit the digital voltage signal to the second microcontroller unit.

[0057] Exemplarily, the second microcontroller unit receives a digital voltage signal from the analog-to-digital conversion circuit, and can determine the target pressure at the deformable part based on the voltage signal and the predicted pressure related to the change in the fitting length of at least one bolt, and transmit a second signal representing the target pressure to the second signal transmission unit.

[0058] For example, the second micro control unit may be implemented by a programmable logic controller (PLC), a microcontroller unit (MCU), etc., which is not limited here.

[0059] The second signal transmission unit is used to transmit the second signal and a sensor identifier representing the flexible pressure sensor to the control device.

[0060] Exemplarily, the second signal transmission unit may include an RFID chip. For example, the RFID chip may transmit the second signal representing the target pressure to the control device based on radio frequency identification technology.

[0061] Figure 3 A deformation monitoring device according to an embodiment of the present invention is shown.

[0062] In one example, if Figure 3 As shown, the deformation monitoring device 130 may include at least one flexible pressure sensor 131, an amplifying and filtering circuit 132, an analog-to-digital conversion circuit 133, a second microcontroller unit 134, and a second RFID chip 135. The at least one flexible pressure sensor 131 may be disposed at the center of each of the hatch, the first side wall panel, the second side wall panel, the third side wall panel, and the fourth side wall panel.

[0063] At least one flexible pressure sensor 131 is connected to the amplifying and filtering circuit 132, the amplifying and filtering circuit 132 is connected to the analog-to-digital conversion circuit 133, the analog-to-digital conversion circuit 133 is connected to the second micro control unit 134, and the second micro control unit 134 is connected to the second RFID chip 135.

[0064] According to an embodiment of the present invention, the pre-tightening force of at least one bolt is , For bolt identification, For each bolt, the method in which the first signal processing unit determines the pre-tightening force of the bolt based on the variation of the fitting length may include:

[0065] Based on the following formula (1), the preload force of the bolt is determined according to the change in the mating length. Formula (1) is:

[0067] In formula (1), is the preload force of the bolt; is the elastic modulus corresponding to the material of the bolt; is the cross-sectional area of ​​the rod; is the change in the mating length of the rod; is the length of the rod.

[0069] According to an embodiment of the present invention, for each easily deformable portion, the second signal processing unit may determine a target pressure at the easily deformable portion based on the voltage signal and a predicted pressure associated with a change in the mating length of at least one bolt, and the method may include:

[0076] According to the initial pressure and predicted pressure , determine the target pressure at the deformable area.

[0077] For example, the initial pressure and predicted pressure The resultant force is determined as the target pressure at the deformable part.

[0078] According to an embodiment of the present invention, Figure 1 As shown, the safety monitoring-based micro-hyperbaric oxygen chamber system 100 may further include an oxygen generator 150, a pressure regulator 160, a temperature and humidity regulator 170, and an environmental monitoring device 180. The oxygen generator 150 is used to create a target oxygen concentration environment within the accommodation space, the pressure regulator 160 is used to create a target air pressure environment within the accommodation space, the temperature and humidity regulator 170 is used to adjust the temperature and / or humidity within the accommodation space, and the environmental monitoring device 180 is used to monitor environmental indicators within the accommodation space, including at least one of the following: an oxygen concentration indicator, an air pressure indicator, a temperature indicator, and a humidity indicator.

[0079] In one example, if Figure 1 As shown, an oxygen generator 150 is connected to the treatment cabin 110 and the control device 140. A pressure regulating device 160 is connected to the treatment cabin 110 and the control device 140. A temperature and humidity regulating device 170 is connected to the treatment cabin 110 and the control device 140. An environmental monitoring device 180 is connected to the control device 140. For example, the oxygen generator 150, the pressure regulating device 160, and the temperature and humidity regulating device 170 may be located outside the treatment cabin 110, and the environmental monitoring device 180 may be located inside the treatment cabin 110.

[0080] For example, the oxygen generator may include a molecular sieve oxygen generator module, the pressure regulator may include a compressor module, and the temperature and humidity regulator may include an air conditioning module.

[0081] Exemplarily, the air conditioning module may include an air conditioner and an air conditioning water treatment unit. The air conditioner is used to adjust the temperature and / or humidity. The air conditioning water treatment unit may be composed of a water storage bottle, a hydraulic sensor and a relay group. Its working process is as follows: the air conditioning water flows into the water storage bottle. When the hydraulic sensor senses that it reaches a certain height, the control device can turn on the relay group to discharge the air conditioning water.

[0082] For example, the environmental monitoring device may include at least one of the following: a gas concentration monitoring unit, an air pressure monitoring unit, a temperature monitoring unit, and a humidity monitoring unit. The gas concentration monitoring unit may be used to monitor an oxygen concentration indicator within the accommodation space, the air pressure monitoring unit may be used to monitor an air pressure indicator within the accommodation space, the temperature monitoring unit may be used to monitor a temperature indicator within the accommodation space, and the humidity monitoring unit may be used to monitor a humidity indicator within the accommodation space.

[0083] According to one embodiment of the present invention, Figure 1 As shown, the safety monitoring-based micro-hyperbaric oxygen chamber system 100 may further include a human-machine interaction device 190 and a voice intercom device 1000, each of which is connected to the control device 140. The human-machine interaction device 190 can, for example, interact with the control device 140 via a touch screen and operating buttons, and the voice intercom device 1000 can, for example, be used to enable conversations and safety warnings between inside and outside the treatment cabin 110. For example, the human-machine interaction device 190 can be located outside the treatment cabin 110, and the voice intercom device can be located both inside and outside the treatment cabin 110.

[0084] According to one embodiment of the present invention, the control device can be used for at least one of the following:

[0085] Based on the oxygen concentration control function, according to the first signal, the second signal and the environmental index, the operating parameters of the oxygen generator are controlled to adjust the oxygen concentration environment in the accommodation space;

[0086] Based on the air pressure control function, according to the first signal, the second signal and the environmental index, the operating parameters of the pressure regulating device are controlled to adjust the air pressure environment in the accommodation space;

[0087] If the constraints are not met, the oxygen generator and pressure regulator are shut down. The constraints represent the yield strength of the materials used for the bolts, hatches, and bulkheads.

[0088] For example, the control device can use PID to control the operating parameters of the oxygen generator to regulate the oxygen concentration environment within the storage space. For example, the control device can use PID to control the operating parameters of the pressure regulator to regulate the air pressure environment within the storage space. For example, the control device can shut down the oxygen generator and the pressure regulator by sending a shutdown command to the oxygen generator and the pressure regulator.

[0089] According to an embodiment of the present invention, the control device can, based on the first signal, the second signal, and the environmental indicator, selectively control the operating parameters of the oxygen generator and / or the pressure regulator, respectively, based on an oxygen concentration control function and / or an air pressure control function, thereby ensuring that the treatment environment within the accommodation space remains stable within a safe range. Furthermore, if the constraints are not met, the oxygen generator and pressure regulator can be promptly shut down to avoid safety accidents, thereby effectively improving the safety and reliability of the micro-hyperbaric oxygen chamber operation and providing users with a comfortable, safe, reliable, and effective micro-hyperbaric oxygen therapy environment.

[0090] According to embodiments of the present invention, n sampling points can be arranged within the treatment cabin. By collecting multiple indicator values ​​at these n sampling points, the treatment environment within the accommodation space can be more accurately characterized.
