Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, specifically to a rehabilitation assistive device for patients with severe acute pancreatitis. Background Technology

[0002] During the recovery period, patients with severe acute pancreatitis have extremely low physical tolerance. Abdominal pressure and improper positioning can easily induce aggravation of abdominal pain or recurrence of the condition. Furthermore, prolonged bed rest can easily lead to complications such as pressure sores and deep vein thrombosis in the lower extremities. Therefore, there are extremely high requirements for proper positioning, pressure control, and convenient nursing care.

[0003] Existing rehabilitation assistive devices often suffer from limited functionality and poor interoperability: some devices can only achieve basic body position adjustment and cannot adaptively adjust the support force based on vital signs such as abdominal pressure and trunk pressure, which can easily lead to pressure on the pancreatic area or prolonged pressure on local skin; some devices require independent equipment for cleaning, massage, and other auxiliary functions, which are cumbersome to operate and may conflict with body position adjustment, increasing the workload of medical staff. In addition, existing devices generally lack a comprehensive safety warning and diagnostic data linkage mechanism, making it difficult to capture and quickly report risks such as abnormal abdominal pressure and pressure concentration in real time. Medical staff need to frequently conduct on-site inspections and manually record data, resulting in low diagnostic and treatment response efficiency and fragmented data that makes it difficult to support the development of personalized rehabilitation plans. This fails to meet the refined and intelligent rehabilitation care needs of patients with severe acute pancreatitis, and targeted improvements are urgently needed.

[0004] Therefore, the present invention proposes a rehabilitation assistive device for patients with severe acute pancreatitis to solve the above-mentioned problems. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a rehabilitation assistive device for patients with severe acute pancreatitis. This device enables precise positioning, real-time monitoring of vital signs, and convenient auxiliary care during the rehabilitation process. Through multi-module linkage and intelligent control, it effectively avoids risks such as abdominal pressure, pressure sores, and lower extremity deep vein thrombosis, reducing the operational and monitoring burden on medical staff. Simultaneously, it achieves real-time collaboration of diagnostic and treatment data, supporting the development of personalized rehabilitation plans and improving the quality of rehabilitation care and the efficiency of treatment response.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A rehabilitation assistive device for patients with severe acute pancreatitis includes a main body, on which a support adjustment module for adapting to the patient's position and a nursing assist module for simplifying nursing operations and assisting in cleaning are installed. A main drive unit is installed inside the main body. The support adjustment module includes a trunk support, an abdominal support, and a lower limb support that are hinged sequentially. Monitoring components are installed on the trunk support, abdominal support, and lower limb support, respectively, for collecting data on the patient's trunk pressure, abdominal pressure, and lower limb blood circulation status. The main drive unit is signal-connected to a control module, which is signal-connected to the monitoring components. The control module is used to control the main drive unit to independently or collaboratively adjust the angle of the support adjustment module according to the real-time status data of the monitoring components.

[0007] The nursing assistance module includes a flow-guiding and cleaning structure that is detachable from the support and adjustment module. The flow-guiding and cleaning structure is used to guide nursing waste fluid in a specific direction. The flow-guiding and cleaning structure automatically unfolds or retracts according to the changes in the body position of the support and adjustment module.

[0008] Furthermore, the main drive unit includes a mounting bracket, a first drive component, and a second drive component. Both the first drive component and the second drive component are fixedly connected to the mounting bracket. The output shaft of the first drive component is coaxially fixedly connected to a bidirectional lead screw. Both ends of the bidirectional lead screw are threaded with nut seats, which are fixedly connected to the torso support and the abdominal support, respectively.

[0009] Furthermore, a gear is coaxially fixedly connected to the output shaft of the second drive unit, and racks mesh on both sides of the gear. A connecting rod is fixedly connected to one end of the rack, and the end of the connecting rod away from the rack is fixedly connected to the torso support and the lower limb support, respectively. Both the first drive unit and the second drive unit are signal connected to the control module.

[0010] Furthermore, the torso support, abdominal support, and lower limb support all have the same structure. The torso support includes a support body with an installation groove inside. Each installation groove contains an elastic dynamic support component. The elastic dynamic support component includes an array of elastic top rods, a partitioned buffer air cushion, and a linkage plate. A spring is fixedly connected to one side of the linkage plate, and the end of the spring away from the linkage plate is fixedly connected to the installation groove. The array of elastic top rods is vertically fixed to the upper surface of the linkage plate, and the end of the array of elastic top rods away from the linkage plate is in contact with the bottom surface of the partitioned buffer air cushion.

[0011] Furthermore, the monitoring components include an abdominal pressure acquisition unit, a trunk pressure acquisition unit, and a lower limb blood circulation monitoring unit. The abdominal pressure acquisition unit includes a pressure-sensitive spring, which is fixedly connected to the corresponding zoned buffer air cushion of the abdominal support. The trunk pressure acquisition unit includes a pressure sensor, which is fixedly connected to the corresponding zoned buffer air cushion of the trunk support. The lower limb blood circulation monitoring unit includes an infrared sensor, which is fixedly connected to the corresponding zoned buffer air cushion of the lower limb support. The pressure-sensitive spring, pressure sensor, and infrared sensor are all connected to the control module for signal transmission.

[0012] Furthermore, the flow-guiding and cleaning structure includes an arc-shaped flow-guiding channel, which is hinged to the sides of the torso support and lower limb support. The inner side of the arc-shaped flow-guiding channel is provided with a leak-proof rubber strip, and a collection box is detachably connected to the bottom of the arc-shaped flow-guiding channel.

[0013] Furthermore, a massage mechanism is installed on the lower limb support. The massage mechanism includes a rolling massage wheel, a synchronous transmission belt, and a driven gear. The driven gear is coaxially and fixedly connected to the output shaft of the second drive component. One end of the synchronous transmission belt is fitted with the driven gear, and the other end of the synchronous transmission belt is connected to the rotating shaft of the massage wheel. The lower limb support is provided with a groove, and the massage wheel and the elastic push rod are staggered and embedded in the groove.

[0014] Furthermore, it also includes an early warning module, which includes an audible and visual warning device. The audible and visual warning device is fixedly connected to the mounting bracket and is connected to the control module via a signal connection. When the abdominal pressure exceeds the threshold or the trunk pressure is abnormally concentrated, the control module activates the audible and visual warning device.

[0015] Furthermore, the edge of the partitioned buffer air cushion is provided with an annular magnetic positioning component, which magnetically engages with the top of the elastic top rod. The magnetic positioning component has a built-in trigger contact, which is connected to the control module signal.

[0016] Furthermore, a wireless transmission module is also provided, which is connected to the control module via a signal. The wireless transmission module is used to connect the data processed by the control module to the diagnosis and treatment system in real time.

[0017] The above approach has the following beneficial effects:

[0018] 1. This solution achieves adaptive coordination of body position adjustment and support pressure by linking the control module with the monitoring component and the main drive unit, combined with the elastic dynamic support component. The abdominal support zone buffer air cushion has a low-pressure avoidance zone corresponding to the pancreatic area, which can accurately avoid abdominal pressure that aggravates the condition. At the same time, it dynamically disperses trunk pressure to prevent pressure sores. Compared with the traditional technology where body position adjustment and pressure support are independent and require repeated manual adjustments, this solution can achieve multiple protective effects without additional drive components. It has higher adjustment accuracy, stronger adaptability, and better meets the special physical needs of patients with severe pancreatitis.

[0019] 2. This solution integrates the linkage logic of the nursing auxiliary module, massage mechanism and main drive unit. The drainage and cleaning structure automatically unfolds and retracts with changes in body position. The massage mechanism uses the power of the second drive component to achieve synchronous operation with the lower limb position adjustment. Neither of them interferes with the core diagnostic and treatment functions. Compared with the traditional technology where cleaning and massage functions need to be implemented with separate equipment, which is cumbersome to operate and easy to conflict with body position adjustment, this solution greatly simplifies the nursing process, reduces the operational burden of medical staff, and improves the comfort and continuity of the patient's recovery process.

[0020] 3. This solution, through the interlocking design of the early warning module, monitoring components, and actuators, combined with the trigger contact protection of the ring-shaped magnetic positioning component, achieves automatic early warning and immediate braking for situations such as abnormal abdominal pressure, pressure concentration, and improper installation of the air cushion, forming a closed-loop safety protection system throughout the entire process. Compared with traditional rehabilitation devices that only have a single early warning function or no protective mechanism, this solution can proactively avoid risks such as worsening of the condition, skin damage, and equipment malfunction, providing more reliable safety protection for critically ill patients and reducing the difficulty of clinical monitoring.

[0021] 4. This solution establishes a two-way data link between the device and the treatment system through a wireless transmission module, enabling real-time uploading of patient vital signs data and device operating status, as well as remote issuance of treatment instructions. Simultaneously, it forms a traceable rehabilitation record. Compared with the traditional technology that requires manual data recording, on-site device operation, and fragmented treatment information, this solution breaks through the limitations of time and space, improves the efficiency of treatment response and data accuracy, helps medical teams develop personalized rehabilitation plans, and promotes the intelligent and standardized upgrading of critical care rehabilitation nursing.

[0028] The following detailed description illustrates the specific implementation method:

[0029] Example 1:

[0030] As attached Figure 1 and Figure 2 The image shows a rehabilitation assistive device for patients with severe acute pancreatitis, comprising a main body, a support adjustment module for adapting to the patient's position, and a nursing assist module for simplifying nursing procedures and assisting with cleaning. A main drive unit is installed within the main body. The support adjustment module includes a trunk support 1, an abdominal support 2, and a lower limb support 3, which are hinged sequentially. Monitoring components are installed on each of the trunk support 1, abdominal support 2, and lower limb support 3. These monitoring components are used to collect data on the patient's trunk pressure, abdominal pressure, and lower limb blood circulation status, respectively. The main drive unit is signal-connected to a control module, which is also signal-connected to the monitoring components. The control module controls the main drive unit to independently or collaboratively adjust the angle of the support adjustment module based on the real-time status data of the monitoring components.

[0031] The nursing support module includes a detachable drainage and cleaning structure that is detachable from the support and adjustment module. This structure directs and guides nursing waste fluid, automatically deploying or retracting according to changes in body position. The drainage and cleaning structure includes an arc-shaped drainage channel, which is hinged to the sides of the torso support 1 and lower limb support 3. An anti-leakage strip is provided on the inner side of the arc-shaped drainage channel, and a collection box is detachably connected to the bottom of the channel.

[0032] The main drive unit includes a mounting frame 4, a first drive component 5, and a second drive component 6. In this embodiment, the first drive component 5 is a first motor, and the second drive component 6 is a second motor. Both the first drive component 5 and the second drive component 6 are fixedly connected to the mounting frame 4. The output shaft of the first drive component 5 is coaxially fixedly connected to a bidirectional lead screw 7. Both ends of the bidirectional lead screw 7 are threaded with nut seats 8, which are fixedly connected to the torso support 1 and the abdominal support 2, respectively. The output shaft of the second drive component 6 is coaxially fixedly connected to a gear 9. Both sides of the gear 9 are meshed with racks 10. One end of the rack 10 is fixedly connected to a connecting rod 11. The end of the connecting rod 11 away from the rack 10 is fixedly connected to the torso support 1 and the lower limb support 3, respectively. Both the first drive component 5 and the second drive component 6 are signal-connected to the control module.

[0033] The torso support 1, abdomen support 2, and lower limb support 3 all have the same structure. The torso support 1 includes a support body with an installation groove inside. Each installation groove contains an elastic dynamic support component. The elastic dynamic support component includes an array of elastic top rods, a partitioned buffer air cushion 12, and a linkage support plate. A spring is fixedly connected to one side of the linkage support plate. The end of the spring away from the linkage support plate is fixedly connected to the installation groove. The array of elastic top rods is vertically fixed to the upper surface of the linkage support plate. The end of the array of elastic top rods away from the linkage support plate is in contact with the bottom surface of the partitioned buffer air cushion 12.

[0034] The monitoring components include an abdominal pressure acquisition unit, a trunk pressure acquisition unit, and a lower limb blood circulation monitoring unit. The abdominal pressure acquisition unit includes a pressure-sensitive spring, which is fixedly connected to the corresponding partitioned buffer air cushion 12 of the abdominal support 2. The trunk pressure acquisition unit includes a pressure sensor, which is fixedly connected to the corresponding partitioned buffer air cushion 12 of the trunk support 1. The lower limb blood circulation monitoring unit includes an infrared sensor, which is fixedly connected to the corresponding partitioned buffer air cushion 12 of the lower limb support 3. The pressure-sensitive spring, pressure sensor, and infrared sensor are all connected to the control module for signal transmission.

[0035] The specific implementation process is as follows: First, the main body of the device is debugged and adapted to the patient. The patient is smoothly moved onto the support and adjustment module of the main body of the device, so that the patient's torso, abdomen, and lower limbs are respectively aligned with the partitioned buffer air cushions 12 of the torso support 1, abdomen support 2, and lower limb support 3. At this time, the control module automatically activates the monitoring components. The pressure-sensitive spring contacts are aligned with the abdominal support 2 air cushion to collect the patient's abdominal pressure data in real time. The pressure sensor captures the pressure distribution on the torso, and the infrared sensor simultaneously monitors the blood circulation status of the lower limbs, realizing comprehensive initial collection of the patient's vital signs data, providing data support for subsequent body positioning and safety protection.

[0036] Based on the initial data acquisition, the control module drives the main drive unit to operate, achieving precise body positioning. If it is necessary to adjust the patient's upper body posture to relieve abdominal pressure, the control module starts the first motor (first drive component 5), whose output shaft drives the bidirectional lead screw 7 to rotate. The nut seats 8 at both ends of the bidirectional lead screw 7 move in the opposite direction along the lead screw axis, respectively driving the torso support 1 to deflect upward and the abdominal support 2 to remain horizontal or slightly downward. Simultaneously, it drives the displacement of the linkage plates within the two—the torso support 1 linkage plate stretches the spring, driving the array of elastic top rods to extend, so that the torso air cushion forms uniform support pressure; the abdominal support 2 linkage plate compresses the spring, and the elastic top rods contract to adapt to the abdominal contour. Combined with the flexibility of the air cushion itself, it achieves adaptive linkage between body positioning adjustment and support pressure, which not only avoids the pancreatic area from being compressed and aggravating abdominal pain, but also reduces the long-term pressure on the local skin of the torso through dynamic support, and simultaneously solves the problems of inaccurate body positioning and pressure ulcer prevention. Compared with the traditional independent adjustment structure, it can achieve dual functions without additional drive, with a compact structure and significantly improved adjustment accuracy.

[0037] When a patient needs to adjust their lower limb position or receive lower limb care, the control module activates the second motor (second drive component 6). The output shaft of the second motor drives the gear 9 to rotate, and the racks 10 meshing on both sides of the gear 9 move in opposite directions horizontally. This drives the trunk support 1 to fine-tune its posture and the lower limb support 3 to tilt upwards or downwards via the connecting rod 11, meeting the patient's comfort needs and providing ample space for nursing operations. During this process, the linkage plate inside the lower limb support 3 moves synchronously with the displacement of the connecting rod 11, and the elastic top rod extends and retracts to adapt to changes in the lower limb angle, ensuring that the lower limb is always in a supportive and conforming state. Simultaneously, the infrared sensor continuously monitors blood circulation data as the air cushion's posture changes. If the data is abnormal, it is fed back to the control module in real time to prevent improper positioning from affecting blood supply to the lower limbs. Through the mechanical linkage of the gear 9, racks 10, and elastic support components, the coordinated operation of lower limb position adjustment, dynamic support, and blood circulation monitoring is achieved. This ensures the safety and comfort of position adjustment without manual intervention, significantly reducing the monitoring workload for medical staff.

[0038] When patient cleaning is required, the control module drives the support adjustment module to adjust to the preset cleaning position (torso support 1 is tilted horizontally, and lower limb support 3 is slightly tilted downwards). During this process, the arc-shaped drainage channel moves synchronously with the change in position, and the leak-proof rubber strip on the inner side adheres to the side of the support to form a sealed barrier. The bottom collection box hangs naturally and is aligned with the drainage direction. The waste liquid generated during cleaning flows directionally into the collection box along the arc-shaped drainage channel, preventing waste liquid leakage and contamination of the device and bed. After cleaning, the collection box can be directly disassembled and emptied for washing. This helps to complete the cleaning operation without disassembling the drainage structure, simplifying the nursing process and reducing the workload of medical staff. At the same time, the adaptable design of the leak-proof rubber strip and the drainage channel improves the convenience of cleaning while ensuring the cleaning effect, solving the pain points of conflict between traditional nursing and position adjustment and cumbersome cleaning procedures.

[0039] During rehabilitation, the monitoring components continuously collect data and feed it back to the control module, forming a closed-loop safety protection system. If the patient's abdominal pressure suddenly increases, the pressure-sensitive spring deforms and transmits a signal to the control module. The control module immediately activates, locking the first motor in operation while simultaneously driving the second motor to finely adjust the lower limb support 3 downwards. Through the gear 9 and rack 10 mechanism, the torso support 1 is slightly lifted, repositioning the patient to alleviate abdominal pressure and prevent further increases in abdominal pressure that could cause fluctuations in the patient's condition. This coordinated protection between the pressure-sensitive spring and the main drive unit enables immediate warning of abnormal abdominal pressure and emergency intervention in postural changes, overcoming the limitations of traditional methods that only provide warnings without intervention. This provides dual protection for patient stability and significantly improves the device's safety performance.

[0040] Throughout the rehabilitation process, the control module continuously records the main drive unit's operating parameters (motor start-stop frequency, body position adjustment angle), the data collected by the monitoring components, and the cleaning operation records, forming a complete rehabilitation file. This provides precise data support for medical staff to assess rehabilitation progress and adjust treatment plans, thus assisting patients in personalized rehabilitation.

[0041] Example 2:

[0042] The difference from Embodiment 1 is that a massage mechanism is installed on the limb support. The massage mechanism includes a rolling massage wheel, a synchronous transmission belt and a driven gear. The driven gear is coaxially and fixedly connected to the output shaft of the second drive member 6. One end of the synchronous transmission belt is fitted with the driven gear, and the other end of the synchronous transmission belt is connected to the rotating shaft of the massage wheel. The lower limb support 3 is provided with a groove, and the massage wheel and the elastic push rod are staggered and embedded in the groove.

[0043] The specific implementation process is as follows: When a patient needs lower limb massage to prevent deep vein thrombosis due to prolonged bed rest, the control module does not require the activation of an independent drive component. It can operate the massage mechanism simply by controlling the second motor (second drive component 6). When the output shaft of the second motor rotates, the coaxially fixed driven gear rotates synchronously, driving the massage wheel shaft to rotate via a synchronous transmission belt. This causes the rolling massage wheel to roll along the groove, providing a gentle rolling massage to the patient's lower limbs. During this process, the second motor can adjust its output speed based on lower limb blood circulation data collected by an infrared sensor, thereby controlling the massage wheel speed (increasing speed when blood circulation is poor and maintaining a constant speed when data is normal), achieving adaptive adjustment of the massage intensity.

[0044] When the second motor drives the gear 9 and rack 10 to adjust the angle of the lower limb support 3, the driven gear synchronously drives the massage wheel to rotate. The elastic push rod extends and retracts with the change of the lower limb support 3 angle, ensuring that the massage wheel always conforms to the contour of the lower limb and avoids suspension or excessive compression during the massage. The slight vibration generated by the rolling of the massage wheel can help promote blood circulation in the lower limb. The infrared sensor captures the blood supply data after the massage in real time and feeds it back to the control module. If the data does not improve, the control module fine-tunes the angle of the lower limb support 3 and the speed of the massage wheel, forming a closed-loop linkage of massage, monitoring and adjustment. By coaxially linking the massage mechanism with the second drive component 6, the massage function can be realized without the need for an additional drive module, which greatly simplifies the device structure and reduces manufacturing costs. At the same time, it breaks through the limitations of traditional massage and body position adjustment operating independently, realizing multi-functional synergy. It not only improves the patient's lower limb comfort, but also effectively prevents venous thrombosis. Compared with independent massage devices, the linkage design significantly improves the adaptability of massage with body position and monitoring.

[0045] The staggered design of the massage rollers and the elastic top rods ensures the massage effect while the dynamic support of the elastic top rods counteracts the local pressure generated by the massage rollers, preventing skin damage caused by excessive pressure on the massage area.

[0046] Example 3:

[0047] The difference from Embodiment 2 is that it also includes an early warning module, which includes an audible and visual early warning device. The audible and visual early warning device is fixedly connected to the mounting bracket 4 and is signal-connected to the control module. When the abdominal pressure exceeds the threshold or the trunk pressure is abnormally concentrated, the control module activates the audible and visual early warning device.

[0048] The specific implementation process is as follows: During the coordinated operation of patient rehabilitation positioning and massage, the early warning module and monitoring components form a real-time linkage. The pressure-sensitive spring on the abdominal support 2 continuously collects abdominal pressure data and transmits it to the control module. The control module presets a safe abdominal pressure threshold suitable for patients with severe pancreatitis. When the abdominal pressure exceeds the threshold due to fluctuations in the patient's condition or minor adjustments in positioning, the control module quickly completes the abnormality judgment and immediately triggers the audible and visual early warning device—emitting a red high-frequency flashing light and a low-frequency alarm sound. The light has strong penetration and can quickly cover the ward area, while the low-frequency alarm sound can effectively remind medical staff while avoiding stimulating the patient and causing discomfort. Through the real-time linkage between the early warning module and the abdominal pressure acquisition unit, the shortcomings of traditional manual monitoring are overcome, realizing automated and rapid warning of abnormal abdominal pressure. This buys medical staff golden time for emergency treatment, effectively avoids the risk of continuously rising abdominal pressure aggravating pancreatic damage, and significantly improves the safety protection level of the device for critically ill patients.

[0049] When the control module drives the main drive unit to adjust the posture of the torso support 1, or when the elastic dynamic support component adaptively adjusts the support pressure, the pressure sensor on the torso support 1 captures pressure distribution data in real time. If abnormal local pressure concentration is detected (exceeding the preset safe pressure value, which can easily lead to pressure sores), the control module immediately activates the audible and visual warning device, and simultaneously links the main drive unit to pause the adjustment action, locking the current body position to prevent continued pressure concentration from aggravating skin damage. After receiving the warning, medical staff can use the pressure distribution data fed back by the control module to precisely adjust the patient's position or check the support component, quickly resolving the abnormal pressure problem.

[0050] Example 4:

[0051] The difference from Embodiment 3 is that the edge of the partitioned buffer air cushion 12 is provided with an annular magnetic positioning component. The magnetic positioning component is magnetically engaged with the top of the elastic top rod. The magnetic positioning component has a built-in trigger contact, which is connected to the control module signal.

[0052] The specific implementation process is as follows: First, the partitioned buffer air cushions 12 are installed and positioned. The corresponding partitioned buffer air cushions 12 for each support body are aligned with the support body mounting groove, ensuring that the annular magnetic positioning element at the edge of the air cushion is precisely aligned with the top of the array of elastic rods within the mounting groove. Relying on the magnetic attraction between the magnetic positioning element and the top of the elastic rod, the initial positioning of the air cushion can be quickly completed without the need for additional fixing components such as bolts or clips, significantly improving efficiency compared to traditional fixing methods. Simultaneously, the magnetic attraction automatically calibrates the air cushion position, ensuring precise contact between the air cushion, elastic rod, and support body mounting groove, avoiding uneven support force caused by manual positioning deviations.

[0053] When the partitioned cushion 12 needs to be replaced (e.g., for cleaning or replacement due to damage), medical staff only need to apply slight external force to separate the magnetic positioning component from the elastic top rod. The trigger contact disconnects simultaneously with the separation, and the control module immediately locks the main drive unit and massage mechanism, preventing accidental device operation that could injure the patient or medical staff during the replacement process. After replacing the air cushion, the magnetic adhesion closes the trigger contact, and the control module automatically unlocks the mechanism, restoring device operation without manual restart or adjustment. The magnetic disassembly and reassembly, along with the linkage design of the trigger contact, enables safe and convenient air cushion replacement. Compared to traditional bolt fixing methods, disassembly and assembly time is shortened, while avoiding damage to the air cushion and support body from tools during disassembly and assembly. This balances maintenance efficiency and component protection, creatively improving the ease of later maintenance of the device.

[0054] Example 5:

[0055] The difference from Embodiment 4 is that a wireless transmission module is also provided. The wireless transmission module is connected to the control module by signal. The wireless transmission module is used to connect the data processed by the control module to the diagnosis and treatment system in real time.

[0056] The specific implementation process is as follows: During device startup and initialization, the wireless transmission module is activated synchronously with the control module, automatically completing encrypted pairing with the diagnostic and treatment system to achieve seamless connection between the device and the system. Simultaneously, the control module automatically integrates the data sources of each component, standardizing the processing of monitoring data and equipment operating status data to ensure that the data uploaded by the wireless transmission module can be directly recognized, displayed, and stored by the diagnostic and treatment system.

[0057] Throughout the patient adaptation and rehabilitation process, the control module continuously collects abdominal pressure data from the pressure-sensitive spring, trunk pressure distribution data from the pressure sensor, and lower limb blood circulation data from the infrared sensor. It simultaneously integrates the main drive unit's posture adjustment parameters, the massage mechanism's operating status, early warning module trigger records, and installation detection signals from the ring-shaped magnetic positioning component. After integrated processing, standardized data messages are generated and uploaded to the diagnostic system via the wireless transmission module in milliseconds. The diagnostic system displays patient vital signs and equipment operating status in real time. Medical staff can remotely monitor the system through nurse station terminals and mobile nursing devices, eliminating the need for frequent bedside rounds and recording, significantly reducing monitoring workload, and enabling continuous 24 / 7 monitoring of patient status. The wireless transmission module achieves real-time integrated uploading of multi-dimensional data, breaking the spatial and temporal limitations of traditional manual recording and on-site monitoring, constructing a remote monitoring link, providing data support for medical staff to accurately grasp the patient's rehabilitation dynamics, and significantly improving clinical monitoring efficiency.

[0058] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
