[0017] The micro-hyperbaric oxygen chamber is a health device that allows users to absorb pure oxygen or high-concentration oxygen in an environment above one atmosphere (1.0ATA). It currently has a wide range of application prospects and clinical promotion value in the field of clinical physical and mental rehabilitation. The micro-hyperbaric oxygen chamber can provide a micro-high pressure environment, allowing more oxygen to dissolve in the blood, and deliver more sufficient oxygen to various tissues and organs of the body, thereby improving physical condition, promoting metabolism, and accelerating cell damage repair.

[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 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 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, vertigo and other diseases.

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

[0020] In the process of realizing the concept of the present invention, the inventors found that the related 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 found that if the impact pressure exceeds the yield strength of the materials of the bulkheads and doors, it will cause permanent damage to the bulkheads and doors, and even cause safety risks such as explosions. Therefore, it is necessary to monitor the impact pressure of the materials of the oxygen chamber. At the same time, repeated alternating impacts will also loosen the bolts that fix the oxygen chamber and the door, which can easily cause air leakage in the oxygen chamber, making it difficult for the internal pressure of the oxygen chamber to reach the setting requirements, or causing the compressor to start and stop repeatedly without interruption. Therefore, it is also necessary to monitor the bolts.

[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, the system comprising a treatment chamber body, a bolt monitoring device, a deformation monitoring device and a control device, wherein: the treatment chamber body comprises 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 a plurality of bolts; the bolt monitoring device is used to monitor the respective preload state of at least one bolt; the deformation monitoring device is used to monitor the respective 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 respective preload state of at least one bolt, and / or according to the respective 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 a closed accommodation space for accommodating a user and at least one wall panel for defining the accommodation space.

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

[0026] Exemplarily, the top wall plate, the bottom wall plate, the first side wall plate, the second side wall plate, the third side wall plate and the fourth side wall plate define a closed accommodation space for accommodating a user. A treatment environment based on a target oxygen concentration and a target air pressure can be formed in the accommodation space. The target oxygen concentration range can be, for example, 85% to 99%, and the target air pressure range can be, for example, 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 fix a wall panel, and the bolt monitoring device can be used to monitor the preload state of at least one bolt to be monitored. Exemplarily, those skilled in the art can reasonably select the bolts to be monitored based on actual needs or application scenarios, for example, bolts at the edges of the wall panels that bear greater pressure, and bolts at vulnerable parts of the treatment cabin can be selected, etc., without specific limitation here.

[0028] As an example, for each bolt to be monitored, the bolt monitoring device can detect its preload force at a first preset frequency, and feed back the detected preload force to the control device, so as to achieve real-time monitoring of the preload state of at least one bolt to be monitored. The first preset frequency can be selected as once every 5 seconds, for example, and there is no limitation here.

[0029] According to an embodiment of the present invention, the 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 at least one wall panel of the treatment cabin, and the deformation monitoring device can be used to monitor the deformation state of at least one wall panel to be monitored. Exemplarily, those skilled in the art can reasonably select the wall panels to be monitored according to actual needs or application scenarios, for example, the first side wall panel, the second side wall panel, the third side wall panel and the fourth side wall panel can be selected, and no specific limitation is made here.

[0030] As an example, for each wall panel to be monitored, the deformation monitoring device can detect its deformation degree according to the second preset frequency, and feed back the detected deformation degree to the control device, so as to realize real-time monitoring of the deformation state of at least one wall panel to be monitored. The second preset frequency can be selected as once every 5 seconds, for example, and there is no limitation here.

[0031] According to an embodiment of the present invention, the control device is used to adjust 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.

[0032] For example, the control device can be used to adjust the treatment environment in the accommodation space according to the preload state of at least one bolt to be monitored. For example, the control device can be used to adjust the treatment environment in the accommodation space according to the deformation state of at least one wall plate to be monitored. For example, the control device can adjust the treatment environment in the accommodation space according to the preload state of at least one bolt to be monitored and the deformation state of at least one wall plate 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, in terms of specific implementation methods, the control device can be implemented in various suitable ways. Those skilled in the art can implement it in a reasonable way according to actual needs or application scenarios, etc., and no limitation is made here. For example, the control device can be implemented by a general-purpose processor ("CPU") or 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 by a programmable logic controller (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 comprises 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 arranged on the cap of the bolt to be monitored, the detection end of the ultrasonic probe is parallel to the rod of the bolt to be monitored, and the ultrasonic probe is used to determine the change in the mating length of the rod based on the ultrasonic signal.

[0040] Exemplarily, the ultrasonic probe may be a transceiver-integrated ultrasonic probe, and the ultrasonic detection end may face the wall plate opposite to the cap. For example, the ultrasonic probe may transmit ultrasonic waves to the wall plate, and process the received ultrasonic waves to calculate the distance between the cap and the wall plate according to the ultrasonic transmission and reception time difference and propagation speed, so as to determine the change in the mating length of the rod based on this. For example, the ultrasonic probe may 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 used to determine the preload force of the bolt based on the variation of the mating length, and transmit the first signal representing the preload force to the first signal transmission unit.

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

[0043] Exemplarily, the first signal processing unit may include a first micro control unit. For example, the first micro control unit may be implemented by a programmable logic controller (PLC), a microcontroller unit (MCU), etc., which is not limited here.

[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 send 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 be used to read the first signal, and transmit the first signal and the bolt identification to the control device through the serial port transmission subunit, wherein 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 micro control 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 arranged on the cap of the bolt to be monitored, and the detection end of the ultrasonic probe 121 is parallel to the rod of the bolt to be monitored. Among them, at least one ultrasonic probe 121 is respectively connected to the first micro control unit 122, the first micro control unit 122 is connected to the first RFID chip 123, and the first RFID chip 123 is connected to the bolt monitoring gateway 124 for communication.

[0048] According to an embodiment of the invention, at least one wall 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] Exemplarily, for each wall panel, during the operation of the micro-hyperbaric oxygen chamber, since the air pressure inside the chamber is higher than the atmospheric pressure outside the chamber, the wall panel will tend to expand outward, so that tensile stress caused by the air pressure difference will be generated at the center of the wall panel. At the same time, since the edge of the wall panel is fixed by bolts, the expansion at the center of the wall panel will be limited by the edge fixing point, thereby generating bending stress caused by the edge fixing at the center of the wall panel. Since the stress state at the center of the wall panel is complex, these stresses may cause deformation or damage at the center of the wall panel, so the flexible pressure sensor can be preferably arranged at the center of the door, the first side wall panel, the second side wall panel, the third side wall panel and the fourth side wall panel.

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

[0054] For example, the flexible pressure sensor can be composed of two layers of flexible electrodes and a functional soft material in the middle. When external pressure acts on the sensor, the functional soft material in the middle is deformed, causing the distance or contact area between the two layers of flexible electrodes to change, thereby causing a change in capacitance or resistance. By measuring these changes, the size and distribution of pressure can be detected. For example, the flexible pressure sensor can be selected as a bridge 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 micro-control unit. For example, the amplifying and filtering circuit may be used 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 used 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 micro-control unit.

[0057] Exemplarily, the second microcontroller unit receives a digital voltage signal from an analog-to-digital conversion circuit, and can determine the target pressure at the deformable point based on the voltage signal and the predicted pressure related to the change in the mating 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 send the second signal representing the target pressure to the control device based on radio frequency identification technology.

[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 respectively disposed at the center 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 respectively 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 preload force of at least one bolt is , For bolt identification, For each bolt, the method in which the first signal processing unit determines the preload force of the bolt based on the change in the mating length may include:

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