Description

Technical Field

[0001] This invention relates to the field of post-anesthesia monitoring equipment, and more specifically to a wearable nursing device for post-anesthesia recovery. Background Technology

[0002] The post-anesthesia recovery period is a critical stage for patients transitioning from anesthesia to wakefulness. During this stage, patients' physiological functions have not fully recovered, often accompanied by confusion, weak spontaneous activity, and unstable circulatory and respiratory functions. They are prone to risks such as abnormal heart rate, fluctuating blood oxygen levels, and microcirculatory disturbances, requiring continuous and precise nursing monitoring and intervention to mitigate these risks. Currently, clinical care for patients in this stage largely relies on traditional restraint devices, distributed physiological monitoring equipment, and manual rounds by medical staff, which has several shortcomings that urgently need to be addressed.

[0003] Firstly, regarding restraint and wearable devices, existing nursing garments or restraint belts are mostly of fixed size, allowing only rough adjustments via Velcro or buckles. This makes it difficult to fit the torso contours of patients with different body types. Furthermore, after adjustment, changes in patient position (such as turning over or limb movement) can easily lead to abnormal local pressure. Too high a setting can cause pressure sores and circulatory disorders, while too low a setting can cause the device to shift or even fall off, rendering the restraint and monitoring ineffective. Secondly, regarding physiological monitoring, single-point monitoring devices (such as finger-clip pulse oximeters and wrist heart rate monitors) are commonly used. These devices provide only one monitoring indicator and are easily affected by patient movement, leading to contact point detachment, data interruption, or distortion. They cannot comprehensively reflect the patient's cardiopulmonary function, microcirculation, and body temperature, among other critical states. Thirdly, regarding early warning and response, reliance on medical staff to periodically check and read data results in delayed detection of abnormalities. Moreover, the timeliness and accuracy of manually adjusting the tightness of the devices are insufficient, making it difficult to meet the rapidly changing physiological needs of patients after anesthesia.

[0004] Based on the aforementioned pain points in clinical nursing, there is an urgent need for a post-anesthesia recovery nursing device that combines adaptive adjustment, comprehensive monitoring, and efficient early warning to improve the quality and safety of nursing care. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a wearable nursing device for post-anesthesia recovery, used for real-time monitoring of physiological indicators, dynamic adjustment of wearing pressure, and risk warning for patients in the post-anesthesia recovery period. Through an integrated structural design and intelligent linkage mechanism, it achieves personalized adaptation, comprehensive monitoring, convenient operation, and refined nursing care, effectively reducing the nursing risks during the post-anesthesia recovery period and improving patient comfort and medical staff efficiency.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: a wearable nursing device for post-anesthesia recovery, comprising a wearable body for conforming to the patient's torso, a monitoring module for real-time monitoring of the patient's physiological data and pressure values, an adaptive component for adjusting the wearable body, and a controller for overall control, wherein the monitoring module includes a pressure sensor for real-time monitoring of the pressure value generated by the wearable body on the patient's torso, and the pressure sensors are all embedded in the inner wall of the wearable body;

[0007] The adaptive component includes several fixed rings, which are evenly distributed on the outside of the wearable body. Each fixed ring has a power component installed inside it. The output shaft of the power component is coaxially and fixedly connected to a gear. Each fixed ring has a rack inserted inside it. Both ends of the rack mesh with the corresponding sides of the gear. The end of the rack away from the gear passes through the fixed ring and is fixedly connected to the wearable body. The power component is signal-connected to the controller. The controller is used to control the opening and closing of the power component based on the real-time pressure value monitored by the pressure sensor.

[0008] When the pressure value is higher than the preset pressure threshold, the controller drives the power component to rotate the gear, which automatically loosens the wearable body through rack and pinion transmission; when the pressure value is lower than the preset pressure threshold, the controller drives the power component to reverse, thereby tightening the wearable body.

[0009] Furthermore, the main body of the wearable device includes an inner skin-friendly layer, a middle elastic adjustment layer, and an outer protective layer; the inner skin-friendly layer has several honeycomb-shaped ventilation holes; the middle elastic adjustment layer has a flow channel cavity, the ventilation holes are connected to the flow channel cavity, and the flow channel cavity has several ventilation holes on the side away from the ventilation holes, and all ventilation holes are located on the outer protective layer.

[0010] Furthermore, the wearable body has Velcro straps at both ends for auxiliary fixation. Flexible pressure contacts are embedded inside the Velcro straps. The flexible pressure contacts are connected to the controller signal. When the pressure sensor fails, the flexible pressure contacts send a signal to the controller to trigger the warning mechanism.

[0011] Furthermore, the monitoring module also includes a physiological sensing unit that integrates heart rate and blood oxygen monitoring functions. The physiological sensing unit includes a housing, and a mounting hole is provided in the middle of the wearable body. A magnetic positioning component for fixing the housing is installed in the mounting hole. The magnetic positioning component includes a ring permanent magnet and a magnetic alloy ring. The ring permanent magnet is embedded in the outer wall of the housing, and the magnetic alloy ring is embedded in the side wall of the mounting hole.

[0012] Physiological sensing units are evenly distributed at the bottom of the housing, and the physiological sensing units and pressure sensors are spaced apart to form a planar monitoring area.

[0013] Furthermore, a universal structure is installed between the physiological sensing unit and the housing. The universal structure includes a ball joint seat and a universal ball. The ball joint seat is fixedly connected to the bottom of the housing. An annular damping ring is fixedly connected to the inner side wall of the ball joint seat. The universal ball is embedded in the end of the ball joint seat away from the housing. The end of the universal ball away from the ball joint seat is fixedly connected to the physiological sensing unit. An annular damping ring is provided inside the ball joint seat. The universal ball and the annular damping ring are interference-fitted. The physiological sensing unit is flush with the inner skin-friendly layer of the wearable body.

[0014] Furthermore, the physiological sensing unit includes an infrared temperature sensor for real-time monitoring of the patient's body temperature, a respiratory sensor for collecting the patient's respiratory rate and respiratory depth, and a pulse perfusion index sensor for detecting the patient's microcirculation perfusion status. The infrared temperature sensor, respiratory sensor, and pulse perfusion index sensor are all connected to the controller signal. The infrared temperature sensor, respiratory sensor, and pulse perfusion index sensor are all integrated in the planar monitoring area at the bottom of the housing, and the detection end face of each sensor is flush with the inner skin-friendly layer of the wearable body.

[0015] Furthermore, the top of the housing is equipped with a touch operation area and a display screen. Both the touch operation area and the display screen are connected to the controller signal. The touch operation area is used to select the patient type and preset pressure threshold, and the display screen is used to display the physiological data and pressure values ​​monitored in real time by the monitoring module to medical staff.

[0016] Furthermore, the controller signal is connected to a wireless communication module, which is connected to the mobile terminal of medical staff and the main unit of the nurse station.

[0017] When abnormal physiological data or pressure values ​​are detected in real time by the monitoring module received by the controller, the controller simultaneously sends an early warning signal to the mobile terminal of medical staff and the host computer at the nurse station.

[0018] Furthermore, the housing surface is provided with a warning component, which includes an indicator light for displaying the status according to the risk level and a buzzer for issuing a warning sound according to the degree of abnormality. Both the indicator light and the buzzer are connected to the controller signal.

[0019] Furthermore, the wearable device is equipped with several sets of adapter interfaces for matching the signal input terminals of various existing monitors. The adapter interfaces include standardized data interfaces and power interfaces. Both the standardized data interfaces and power interfaces are equipped with sealing covers for dust and water protection.

[0020] The above approach has the following beneficial effects:

[0021] 1. This solution enables adaptive adjustment of the tightness of the wearable device, effectively avoiding complications caused by abnormal local pressure. Compared with traditional technologies that rely on medical staff to manually adjust restraint straps or nursing clothing, which have poor timeliness and difficulty in accurately controlling pressure, this solution uses a closed-loop control system that monitors pressure in real time and links the controller to the power components. It can automatically loosen or tighten the device immediately when the pressure value exceeds or falls below a preset threshold, keeping the pressure of the wearable device on the patient's torso within a safe range. This greatly reduces the risk of pressure sores and blood circulation disorders caused by excessive pressure, or device displacement and monitoring failure caused by excessively low pressure.

[0022] 2. This solution constructs a multi-dimensional, area-covering physiological monitoring system, providing comprehensive data support for assessing the patient's condition during the post-anesthesia recovery period. Compared with traditional technologies that often employ single-point physiological monitoring, have limited monitoring indicators, and are prone to monitoring interruptions due to changes in body position, this solution not only integrates monitoring functions for multiple key physiological indicators such as heart rate, blood oxygen, body temperature, respiratory rate, respiratory depth, and microcirculation perfusion status, but also ensures that the physiological sensing unit is always in close contact with the patient's skin and that the probe end is flush with the skin-friendly layer through magnetic positioning components and an omnidirectional structural design. Combined with the spaced distribution of pressure sensors and physiological sensing units, this forms an area-covering monitoring region without blind spots, significantly improving the completeness and accuracy of the monitoring data.

[0023] 3. This solution has multiple early warning mechanisms and efficient information transmission capabilities, providing a guarantee for timely intervention by medical staff. Compared with traditional technologies that rely on regular rounds by medical staff as the main early warning method and are prone to delays in treatment due to human negligence, when monitoring data is abnormal, it can provide local early warning through indicator lights (distinguished by risk level) and buzzers (with adjustable prompt tone according to the degree of abnormality) on the surface of the housing. It can also send early warning signals to the mobile terminals of medical staff and the host of the nurse station through the wireless communication module. At the same time, when the pressure sensor fails, the flexible pressure contact can immediately trigger the backup early warning mechanism, which greatly shortens the abnormal response time.

[0024] 4. This solution optimizes the wearability and practicality of the device, improving patient comfort and nursing adaptability after anesthesia. Compared with traditional technologies where nursing devices are mostly of universal size, have poor skin-friendliness, and lack breathability, the main body of the wearable device adopts a composite structure of a skin-friendly layer, an elastic adjustment layer, and a protective layer. The honeycomb-shaped ventilation holes of the inner skin-friendly layer, the middle drainage cavity, and the outer ventilation holes form a complete ventilation channel, effectively reducing sweat accumulation and stuffiness. The Velcro straps facilitate quick and easy wearing and fixing, while the magnetic positioning component enables convenient disassembly and precise positioning of the physiological sensing unit. At the same time, the adapter interface can be connected to various existing monitors, taking into account both patient comfort and compatibility and operability in clinical nursing.

[0025] 5. This solution enables personalized setting of nursing parameters and data visualization management, meeting the nursing needs of different patients. Compared with the shortcomings of traditional technologies, such as fixed nursing device parameters, inability to flexibly adjust according to individual patient differences, and inconvenient reading of monitoring data, this solution allows medical staff to select patient types and preset pressure thresholds based on information such as patient age, weight, and anesthesia type through the touch operation area on the top of the casing. The display screen can intuitively display various physiological data and pressure values ​​in real time, making it easy for medical staff to quickly grasp the patient's status. At the same time, the standardized data interface also provides convenience for the subsequent storage, analysis, and traceability of monitoring data, helping to implement refined nursing care.

[0026] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] The following detailed description illustrates the specific implementation method:

[0037] Example 1:

[0038] As attached Figures 1 to 5 As shown: A wearable nursing device for post-anesthesia recovery includes a wearable body 1 for conforming to the patient's torso. The wearable body 1 includes an inner skin-friendly layer 102, a middle elastic adjustment layer 104, and an outer protective layer 106. The inner skin-friendly layer 102 has several honeycomb-shaped ventilation holes 103. The middle elastic adjustment layer 104 has a drainage cavity 105, and the ventilation holes 103 communicate with the drainage cavity 105. Several ventilation holes 107 are formed on the side of the drainage cavity 105 away from the ventilation holes 103. The ventilation holes 107 are all formed on the outer protective layer 106 (e.g., ...). Figure 5 (As shown).

[0039] The wearable body 1 is equipped with a monitoring module for real-time monitoring of the patient's physiological data and pressure values, an adaptive component for adjusting the wearable body 1, and a controller for overall control. The monitoring module includes pressure sensors for real-time monitoring of the pressure values ​​generated by the wearable body 1 on the patient's torso, and the pressure sensors are all embedded in the inner wall of the wearable body 1. The monitoring module also includes a physiological sensing unit with integrated heart rate and blood oxygen monitoring functions. The physiological sensing unit includes a housing 5, and a mounting hole 6 is opened in the middle of the wearable body 1. A magnetic positioning component for fixing the housing 5 is installed in the mounting hole 6. The magnetic positioning component includes a ring permanent magnet 7 and a magnetically conductive alloy ring. The ring permanent magnet 7 is embedded in the outer wall of the housing 5, and the magnetically conductive alloy ring is embedded in the side wall of the mounting hole 6. The physiological sensing units are evenly distributed at the bottom of the housing 5, and the physiological sensing units and pressure sensors are spaced apart to form a planar monitoring area.

[0040] The physiological sensing unit includes an infrared temperature sensor for real-time monitoring of the patient's body temperature, a respiratory sensor for acquiring the patient's respiratory rate and depth, and a pulse perfusion index sensor for detecting the patient's microcirculation perfusion status. The infrared temperature sensor, respiratory sensor, and pulse perfusion index sensor are all connected to the controller. They are all integrated into the planar monitoring area at the bottom of the housing 5. Compared to traditional distributed installations, this avoids interference between the airflow detection of the respiratory sensor and the blood flow signal acquisition of the pulse perfusion index sensor, and also provides complete planar coverage of the monitoring range, offering structural support for simultaneous multi-parameter monitoring. Furthermore, the detection surfaces of each sensor are flush with the inner skin-friendly layer 102 of the wearable body 1. On the one hand, it avoids point contact problems caused by sensor protrusion, ensuring that each sensor detection surface forms a uniform surface contact with the skin; on the other hand, the flush design, combined with the flexible buffer of the inner skin-friendly layer 102, keeps the contact pressure between the sensor and the skin stable within the pressure threshold range. This prevents the microcirculation data from being distorted due to excessive pressure compressing local blood vessels, and also prevents contact gaps from appearing due to insufficient pressure, ensuring that the respiratory sensor can accurately capture the pressure changes caused by the rise and fall of the chest.

[0041] The adaptive component includes several fixed rings 2, which are evenly distributed on the outside of the wearable body 1. Each fixed ring 2 has a power component installed inside it. In this embodiment, the power component is a motor. The output shaft of the power component is coaxially and fixedly connected to a gear 3. Each fixed ring 2 has a rack 4 inserted inside it. The two ends of the rack 4 are respectively engaged with the two sides of the corresponding gear 3. The end of the rack 4 away from the gear 3 passes through the fixed ring 2 and is fixedly connected to the wearable body 1. The power component is signal-connected to the controller. The controller is used to control the opening and closing of the power component according to the real-time pressure value monitored by the pressure sensor. When the pressure value is higher than the preset pressure threshold, the controller drives the power component to rotate the gear 3. The gear 3 drives the racks 4 on both sides to move in opposite directions at the same time, so that the rack 4 drives the wearable body 1 to automatically expand. When the pressure value is lower than the preset pressure threshold, the controller drives the power component to reverse, so that the wearable body 1 tightens.

[0042] This embodiment employs a closed-loop control logic, from pressure monitoring to intelligent judgment and finally mechanical adjustment, to maintain the pressure of the wearable device 1 on the patient's torso within a safe range. This significantly reduces the risk of pressure sores and circulatory disorders caused by excessive pressure, or device displacement and monitoring failure caused by insufficient pressure. Especially for patients who are post-anesthesia confused and unable to report discomfort, this mechanism can replace frequent manual checks and adjustments, ensuring patient safety while significantly reducing the nursing burden on medical staff and improving the efficiency and quality of post-anesthesia recovery care.

[0043] The wearable main body 1 is equipped with several sets of adapter interfaces for matching with the signal input terminals of various existing monitors. The adapter interfaces include standardized data interfaces and power interfaces. Both the standardized data interfaces and power interfaces are equipped with sealing covers for dust and water protection.

[0044] The specific implementation process is as follows: Medical staff, based on the patient's body type (e.g., child, adult, or obese patient), first manually adjust the connection status at both ends of the wearable body 1 to initially fit the patient's torso, without complex assembly. At this time, the inner skin-friendly layer 102 of the wearable body 1 is in direct contact with the patient's skin. The honeycomb-shaped ventilation holes 103 and the guiding cavity 105 of the middle elastic adjustment layer 104 form a ventilation channel. The ventilation holes 107 of the outer protective layer 106 ensure air circulation and prevent skin stuffiness. The ventilation holes 103 adopt a regular hexagonal array design. When the wearable body 1 is subjected to the tightening force adjusted by the adaptive components or the local pressure generated by changes in the patient's body position, the honeycomb structure of each ventilation hole 103 can decompose the concentrated pressure into a dispersed force along the tangential direction of the hole wall of the ventilation hole 103, reducing the pressure originally acting on the local skin and effectively avoiding skin pressure injuries caused by excessive pressure at a single contact point. This is especially beneficial for infants and young children with delicate skin, significantly reducing the risk of pressure sores. The physiological sensing unit housing 5, which integrates a heart rate sensor, blood oxygen sensor, infrared temperature sensor, respiration sensor, and pulse perfusion index sensor, is aligned with the mounting hole 6 in the middle of the wearable body 1. The housing 5 automatically centers and positions itself through the magnetic attraction between the annular permanent magnet 7 on the outer wall of the housing 5 and the magnetically conductive alloy ring on the side wall of the mounting hole 6, requiring no additional calibration. Furthermore, the tight fit between the housing 5 and the mounting hole 6 of the wearable body 1 further restricts the axial and circumferential displacement of the housing 5. Even if the wearable body 1 undergoes expansion and contraction due to adaptive adjustment, the housing 5 remains in the preset mounting position, thus ensuring that the displacement values ​​of all sensors in the physiological sensing unit are well below the displacement tolerance threshold for effective sensor monitoring.

[0045] Based on the patient type (such as infants or adults), medical staff can preset the pressure safety threshold of the wearable body 1 on the patient's torso through the controller to ensure that it is suitable for the comfortable pressure bearing needs of patients of different body types and avoid skin pressure injuries caused by improper tightness.

[0046] After the device is activated, all sensors work synchronously: the pressure sensor collects the pressure value between the wearable body 1 and the patient's torso in real time; the heart rate and blood oxygen sensors collect basic vital signs; the infrared temperature sensor monitors core body temperature; the respiration sensor captures respiratory rate and depth; and the pulse perfusion index sensor detects microcirculation status. The detection surfaces of all sensors are flush with the skin-friendly layer, with no hard protrusions that compress the skin or surgical area, improving wearing tolerance; the area-distributed sensors ensure comprehensive monitoring data coverage, eliminating the need for multiple additional devices.

[0047] The controller receives real-time monitoring data from the pressure sensor. When the pressure value exceeds a preset threshold, the controller drives the power component (motor) inside the fixed ring 2 to start. The output shaft of the power component drives the gear 3 to rotate. Through the meshing transmission between the rack 4 and the gear 3, the gear 3 drives the racks 4 on both sides to move in opposite directions (the two racks 4 move in opposite directions respectively). Figure 2The controller moves the left and right sides of the device, causing the wearable body 1 to expand synchronously, automatically increasing its circumference and reducing contact pressure. When the pressure value is lower than the preset threshold (the minimum pressure to ensure effective contact monitoring), the controller drives the power component to reverse, the gear 3 reverses its transmission, and the gear 3 drives the racks 4 on both sides to move in opposite directions (the two racks 4 move towards the opposite directions respectively). Figure 2 The device moves in the middle direction, causing the wearable body 1 to tighten, maintaining a stable monitoring contact state, achieving dynamic pressure balance, and adapting to pressure changes caused by changes in patient position or body shape. This helps maintain the pressure of the wearable body 1 on the patient's torso within a safe range, while greatly reducing the risk of pressure sores and circulatory disorders caused by excessive pressure, or device displacement and monitoring failure caused by excessive pressure.

[0048] After the monitoring data is processed by the controller, it can be directly connected to various existing monitors through the standardized data interface on the wearable body 1 to achieve real-time data synchronization. At the same time, the sealed cover can protect the interface from dust and water when closed, adapting to the humid environment of postoperative care, without the need for additional adaptation and conversion equipment, thus improving clinical practicality.

[0049] After the monitoring is completed, medical staff manually separate the physiological sensor unit housing 5 from the mounting hole 6 (by overcoming the magnetic attraction force), and then unfasten the fixing structure of the wearable body 1 to quickly complete the disassembly. The whole process is simple and does not require complicated disassembly of components.

[0050] Example 2:

[0051] As attached Figure 1 As shown, the difference from Embodiment 1 is that the wearable body 1 has Velcro straps 101 for auxiliary fixation at both ends. Flexible pressure contacts are embedded in the inner side of the Velcro straps 101. The flexible pressure contacts are connected to the controller signal. When the pressure sensor fails, the flexible pressure contacts send a signal to the controller to trigger the warning mechanism.

[0052] The specific implementation process is as follows: After the medical staff wraps the main body 1 around the patient's torso, they take the Velcro straps 101 at both ends of the main body 1 (the active strap with hook and loop side and the passive strap with loop side, respectively). They adjust the overlap length according to the patient's body shape, and first attach the hook and loop side of the active strap to the loop side of the passive strap for initial fixation. At this time, the flexible pressure contact embedded on the inner side of the strap comes into contact with the skin on the side of the patient's torso as the strap is attached. Because the initial fixation pressure is relatively gentle, the contact is in a low signal standby state.

[0053] After initial fixation, medical staff gently pull the end of the strap for fine-tuning until they feel the strap fits snugly against the torso without feeling tight. At this point, the flexible pressure contact is moderately squeezed, sending an initial pressure signal to the controller. The controller uses this signal as a reference value for strap fixation, forming a dual pressure monitoring dimension with the pressure sensor data inside the wearable body 1, ensuring that the fixation strength meets the monitoring requirements while avoiding excessive pressure.

[0054] When a patient turns over or moves during recovery, if the main body of the garment 1 shifts, the contact pressure of the Velcro strap 101 will change accordingly. The flexible pressure contact collects pressure fluctuation data in real time and transmits it to the controller. When the pressure fluctuation exceeds the pressure fluctuation threshold in the controller, the controller simultaneously compares the pressure sensor data. If the trends of the two are consistent, the pressure change is recorded only in the background; if the pressure sensor does not report a corresponding change (indicating a possible malfunction of the main sensor), the independent signal from the flexible pressure contact immediately triggers the controller's early warning preparation program.

[0055] When the pressure sensor inside the wearable body 1 malfunctions (such as no signal output or signal malfunction), the flexible pressure contact becomes the core pressure monitoring element. If it detects a pressure value exceeding the preset safety threshold, it immediately sends an abnormal signal to the controller, which then activates an early warning mechanism, prompting medical personnel to promptly check the device status and manually adjust the fit of the Velcro strap 101.

[0056] When the device needs to be removed, medical staff pinch the separating end of the Velcro strap 101 and gently tear it in a direction perpendicular to the bonding surface to separate the hook and loop side from the nap side. At this time, the pressure of the flexible pressure contact drops sharply, sending a "strap detachment" signal to the controller. The controller automatically records the disassembly time and pauses the pressure monitoring program to avoid false alarms.

[0057] Example 3:

[0058] As attached Figure 3 and Figure 4 As shown, the difference from Embodiment 2 is that a universal structure is installed between the physiological sensing unit and the housing 5, enabling 360° angle adjustment of the physiological sensing unit. The universal structure includes a ball joint seat 8 and a universal ball 9. The ball joint seat 8 is fixedly connected to the bottom of the housing 5, and an annular damping ring 10 is fixedly connected to the inner side wall of the ball joint seat 8. The universal ball 9 is embedded in the end of the ball joint seat 8 away from the housing 5, and the end of the universal ball 9 away from the ball joint seat 8 is fixedly connected to the physiological sensing unit. The annular damping ring 10 is provided inside the ball joint seat 8, and the universal ball 9 and the annular damping ring 10 are interference-fitted. The physiological sensing unit is flush with the inner skin-friendly layer 102 of the wearable body 1.

[0059] When the patient turns over, lies on their side, or makes slight trunk movements during the recovery period after anesthesia, the omnidirectional ball 9 can flexibly rotate within the ball joint 8 according to the skin contact angle, ensuring that the detection end faces of each sensor are in close contact with the skin. This helps to solve the contact gap problem caused by changes in body position in traditional fixed sensors, significantly reducing the interruption rate of monitoring key data such as heart rate and blood oxygen. The interference fit between the annular damping ring 10 and the omnidirectional ball 9 provides stable damping force, and the adjusted sensing unit can be precisely maintained at the appropriate angle without angle rebound due to fluctuations in the patient's breathing or slight agitation. This effectively controls the fluctuation range of the contact pressure between the sensor and the skin, further reducing the monitoring error of sensitive indicators such as microcirculation perfusion.

[0060] The specific implementation process is as follows: After the medical staff completes the magnetic fixation of the physiological sensing unit and the wearable body 1, they observe the fit between the physiological sensing unit and the patient's skin. If there is any local suspension or uneven fit, they gently push the shell 5 with their fingers. At this time, the universal ball 9 rotates flexibly in the direction of the push force within the ball joint seat 8 until the detection end face of the physiological sensing unit is completely flush with the inner skin-friendly layer 102 of the wearable body 1.

[0061] When patients change position during the recovery period, such as turning over or lying on their side, the skin of the torso will cause slight deformation of the wearable body 1, and the physiological sensing unit will be subjected to lateral thrust from the skin. The omnidirectional ball 9, through damping cooperation with the annular damping ring 10, can slowly rotate in the direction of the force, so that the detection end face of the physiological sensing unit is always in contact with the skin surface, avoiding the sensor from shifting or tilting due to changes in body position.

[0062] When the patient's surgical area is near the monitoring area, medical staff can gently bend the physiological sensing unit away from the surgical area, depending on its location. The omnidirectional structure drives the sensor to rotate around the center of the ball joint 8, ensuring that the detection end face of the physiological sensing unit avoids the surgical wound while maintaining close contact with the surrounding skin. During adjustment, the damping force provided by the annular damping ring 10 prevents over-adjustment, protecting the surgical area from pressure without affecting the monitoring range.

[0063] After cleaning the sensor or maintaining the device, if the omnidirectional structure shifts at an angle, medical staff only need to gently rotate the physiological sensing unit back to its initial fit position and feel slight resistance to confirm that the reset is complete. The interference fit design of the omnidirectional ball 9 and the annular damping ring 10 prevents loosening of the angle after routine maintenance, ensuring consistent monitoring accuracy in every use.

[0064] Example 4:

[0065] The difference from Embodiment 3 is that the top of the housing 5 is provided with a touch operation area 501 and a display screen 502. Both the touch operation area 501 and the display screen 502 are connected to the controller signal. The touch operation area 501 is used to select the patient type and preset pressure threshold, and the display screen 502 is used to display the physiological data and pressure values ​​monitored in real time by the monitoring module to medical staff.

[0066] The specific implementation process is as follows: For example, after medical staff complete the fixation of the wearable main body 1 and the installation of the physiological sensing unit, the display screen 502 automatically jumps to the "Patient Type Selection" interface, displaying four options: "Infant," "Child," "Adult," and "Obese Patient." Each option is labeled with its corresponding default pressure threshold range. Based on the patient's actual condition, the medical staff lightly touches the touch button corresponding to the option on the touch operation area 501. Upon triggering the touch button, a "beep" confirmation sound is emitted, and the display screen 502 simultaneously highlights the selected patient type and pops up a secondary confirmation window: "Confirm selection of XX type?" Touching the "Confirm" button again completes the setting, and the device automatically loads the pressure threshold standard and sensor calibration parameters for that patient type.

[0067] If the pressure threshold needs to be adjusted based on the patient's specific condition (such as skin sensitivity or postoperative positioning requirements), after the patient type is set, medical staff can lightly touch the "Threshold Adjustment" button on the touch operation area 501. The display screen 502 will switch to the threshold setting interface, displaying the current pressure threshold on the left and "+" and "-" touch adjustment buttons on the right. Touching the "+" button increases the threshold by a unit pressure value, while touching the "-" button decreases it by a unit pressure value. The display screen 502 refreshes the values ​​in real time during the adjustment process. After adjusting to the target threshold, lightly touch the "Save" button. The display screen 502 will pop up a "Threshold saved" prompt box and automatically return to the main monitoring interface. The backlight of the touch operation area 501 will then dim to reduce light interference to the patient.

[0068] Once the device enters monitoring mode, the display screen 502 defaults to displaying core data in the "main interface" mode, including three key indicators: heart rate, blood oxygen saturation, and real-time pressure value. The data is displayed in large font and centered, with clear unit labels. At the bottom, auxiliary indicators such as body temperature and respiratory rate are displayed in small data blocks.

[0069] Example 5:

[0070] The difference from Embodiment 4 is that the controller is connected to a wireless communication module, which is connected to the mobile terminal of medical staff and the host computer of the nurse station. When the physiological data or pressure value monitored in real time by the monitoring module received by the controller becomes abnormal, the controller simultaneously sends an early warning signal to the mobile terminal of medical staff and the host computer of the nurse station.

[0071] The housing 5 has a warning component on its surface, which includes an indicator light for displaying the status according to the risk level and a buzzer for issuing a warning sound according to the degree of abnormality. Both the indicator light and the buzzer are connected to the controller signal.

[0072] The specific implementation process is as follows: Before activating the nursing device, medical staff connect to their mobile terminals (phones / tablets) and the nurse station host via Bluetooth / Wi-Fi signals through a wireless communication module. After completing the wireless connection, medical staff, based on the patient's condition (e.g., high-risk postoperative, normal recovery), preset three levels of abnormal risk thresholds through the touch operation area 501, corresponding to different response modes of the warning components:

[0073] Level 1 Risk Warning Response: When the monitoring module detects a Level 1 risk anomaly, the controller immediately triggers the basic response of the warning component: the indicator light turns yellow and remains constantly on, and the buzzer emits an intermittent "beep-beep" sound to avoid disturbing the patient's rest; at the same time, the wireless communication module pushes the warning information to the mobile terminal of medical staff in the form of a "text message", the content of which includes "Patient XX (bed number) has a Level 1 risk", and the corresponding patient icon on the monitoring interface of the nurse station host flashes yellow without sound prompts, only reminding medical staff to pay attention.

[0074] Level 2 Risk Warning Linkage: If the monitored data reaches the Level 2 risk standard, the warning component upgrades its response: the indicator light flashes yellow rapidly, the buzzer's frequency and volume increase; the wireless communication module simultaneously initiates multi-channel push notifications, sending a "text + vibration" alert to the mobile terminal; the nurse station host emits a low-volume alert tone; and a small window pops up on the monitoring interface displaying the abnormal data and the patient's bed number, facilitating priority handling by nurses. At this time, medical staff can click "Known" on the mobile terminal APP. This feedback information is transmitted back to the controller via the wireless communication module, and the controller pauses the buzzer while the indicator light continues to flash until the abnormality is resolved.

[0075] Level 3 Risk Emergency Warning: When a Level 3 high-risk abnormality occurs, the warning component activates the highest level of response: the indicator light immediately switches to solid red and flashes rapidly, and the buzzer emits a continuous long tone; the wireless communication module contacts the responsible medical staff in the form of "text + telephone reminder". If no feedback is received from the mobile terminal within a unit of time, it automatically transfers to the nurse station host and triggers a high-decibel alarm. The nurse station host monitoring interface displays the patient information and abnormal data in full screen, and at the same time, it activates the sound and light alarm in the department corridor to ensure a rapid response to emergencies.

[0076] After the medical staff handles the abnormal situation, the patient's physiological data returns to normal. The controller detects that the data has returned to a safe range and immediately controls the early warning component to reset: the indicator light switches to solid green and the buzzer stops sounding; the wireless communication module pushes a confirmation message "Patient XX's abnormality has been resolved and the current status is normal" to the mobile terminal and the nurse station host in real time. The nurse station host automatically records the time and result of the abnormality handling, the mobile terminal generates an "Abnormality handling completed" log, and all data is synchronously archived through the wireless communication module for easy follow-up.

[0077] 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.
