Description

Technical Field

[0001] This invention relates to the field of medical supplies technology, specifically to a head dressing fixation device. Background Technology

[0002] In neurosurgical clinical treatment, postoperative head surgery (such as craniocerebral tumor resection, decompressive craniectomy, etc.) requires the use of dressing fixation devices to secure the wound dressing and prevent it from shifting or falling off. Simultaneously, drainage tubes are needed to drain any blood or fluid, ensuring a healthy wound healing environment and treatment safety. Currently, the most commonly used methods for head dressing fixation in clinical practice are two main types: ordinary degreased bandage wrapping and simple elastic headgear fixation.

[0003] Ordinary degreasing bandages require manual wrapping around the head 3-5 times from different directions to achieve fixation. The tension of these bandages depends entirely on the manual binding force of medical staff, which cannot be precisely controlled. This can easily lead to problems such as excessively tight bandaging causing headaches and affecting scalp blood circulation, or excessively loose bandaging causing device displacement and dressing detachment. Furthermore, the bandages lack a special anti-slip structure, making them prone to shifting when the patient moves, which can cause the dressing to move to the incision and cause contamination. For patients with drainage tubes, bandage displacement can also cause rigid drainage tubes to tilt or shift, thereby damaging brain tissue, or cause soft drainage tubes to be compressed, resulting in poor drainage, or even partial or complete dislodgement, leading to serious risks such as the inability to drain fluid.

[0004] Simple elastic headbands achieve fixation through elastic contraction, but their single-size design limits their applicability, only meeting the basic fixation needs of patients with regular head shapes and no drainage tubes. The headbands tightly compress the scalp, and prolonged wear can affect blood supply to the scalp, causing discomfort and hindering wound healing. Furthermore, the fixation straps can leave marks on the chin. For patients with drainage tubes, the elastic headbands are difficult to apply, and the tubes are not easily pulled out through gaps. Some doctors need to cut the headband at the point of compression corresponding to the drainage tube, which can cause the dressing to fall off, making it impossible to balance fixation and drainage needs.

[0005] Furthermore, existing fixation devices all have monitoring functions, making it impossible for medical staff to promptly detect any abnormalities during the patient's wearing process. This necessitates frequent disassembly and reassembly of the devices to observe the wound and drainage status, which not only increases the workload of medical staff but also increases the risk of touching the wound and pulling the drainage tube during disassembly, disrupting the wound healing environment and increasing the risk of secondary injury. At the same time, the materials in contact with the skin of existing devices are mostly ordinary synthetic fiber cloth or untreated cotton cloth, which lack breathability and sweat-absorbing design. Long-term wear can easily lead to the accumulation of sweat, creating a hot and humid environment, which can cause skin redness, itching, or even infection, significantly reducing patient treatment compliance.

[0006] Therefore, there is an urgent need for a head dressing fixation device that combines precise fixation, intelligent adaptation, comfort, safety, and ease of operation to address the many shortcomings of existing technologies. Summary of the Invention

[0007] To address the aforementioned issues, this invention provides a head dressing fixation device for the stable fixation of dressings after neurosurgical head surgery (including craniocerebral surgery, decompressive craniectomy, etc.). It is adaptable to patients with different head circumferences and irregular head shapes, enabling precise pressure control, safe protection of drainage tubes, real-time monitoring of wearing status, and convenient clinical operation. This reduces complications such as secondary wound damage, infection, and drainage failure, thereby improving treatment safety and patient comfort.

[0008] To achieve the above objectives, the technical solution of the present invention is as follows: A head dressing fixation device includes a main body, which includes a shell for conforming to the contour of the head. An elastic band is installed inside the shell. A quick-release module for quick removal and avoiding pulling on the wound and a head shape adaptive module for adapting to irregular head shapes are installed on the shell. The quick-release module is installed at both ends of the shell. The head shape adaptive modules are distributed at the positions of the shell corresponding to the forehead, occiput, and both sides of the temporal region. The shell has several mounting cavities. A zoned pressure adjustment module for adjusting pressure to adapt to different head circumferences and intracranial pressure control requirements, an anti-slip anchoring module for enhancing the friction between the shell and the scalp to prevent the device from shifting when the patient moves, and a drainage tube protection module for accommodating and protecting the drainage tube from pressure, folding, and pulling are installed in the mounting cavities. The zoned pressure adjustment modules are symmetrically installed at the positions of the shell corresponding to the forehead and occiput. The anti-slip anchoring modules are located on the inner side of the shell corresponding to the temporal region. The drainage tube protection modules extend along the edge of the shell and are elastically connected to the shell. The zoned pressure adjustment modules and the anti-slip anchoring modules are linked to form a triangular stable fixation structure.

[0009] The housing is also equipped with a monitoring module for real-time monitoring of head stress, skin condition, and drainage tube patency. The monitoring module is connected to a control module, which is connected to the zone pressure adjustment module, anti-slip anchoring module, and head shape adaptive module. The control module is used to automatically adjust the zone pressure adjustment module based on the pressure data, skin humidity data, and drainage tube flow data collected by the monitoring module.

[0010] Furthermore, the monitoring module includes a pressure sensing unit, a skin condition monitoring unit, and a drainage monitoring unit; the pressure sensing unit includes a pressure sensor for collecting the contact pressure between the zoned pressure regulating module and the head, and the pressure sensor is attached to the surface of the zoned pressure regulating module; the skin condition monitoring unit includes a humidity sensor for detecting the accumulation of sweat on the scalp, and the humidity sensor is embedded inside the anti-slip anchoring module; the drainage monitoring unit includes a flow sensor for monitoring the flow rate of the drainage fluid, and the flow sensor is housed inside the drainage tube protection module.

[0011] Furthermore, the zoned pressure regulating module includes an electric regulating component, which includes a drive component. The drive component is fixedly connected to the mounting cavity. The output shaft of the drive component is coaxially fixedly connected to a worm gear, which meshes with a worm. One end of the worm is wound and connected to an elastic band that passes through the mounting cavity. The drive component is signal-connected to the control module. The control module drives the drive component to rotate forward or backward according to the pressure data collected by the pressure sensing unit. The worm gear and worm drive cause the elastic band to contract or relax.

[0012] Furthermore, the anti-slip anchoring module includes an adaptive deformation seat, a silicone anti-slip pad, and a power component; the adaptive deformation seat has an arc-shaped hollow structure, and the power component is embedded inside the adaptive deformation seat, which is electrically connected to the control module; the silicone anti-slip pad is detachably connected to the inner side of the adaptive deformation seat, and the surface of the silicone anti-slip pad is provided with a honeycomb anti-slip texture and avoidance holes corresponding to the humidity sensor; when the humidity sensor detects excessive sweat, the control module drives the silicone anti-slip pad to deform, so that the silicone anti-slip pad forms a dynamic fit with the scalp.

[0013] Furthermore, the head shape adaptive module includes several sets of detachable elastic adjustment units. Each elastic adjustment unit includes a shape memory alloy adjustment plate, which is embedded along the length of the inner wall of the housing. An electric push rod is installed between the shape memory alloy adjustment plate and the housing. A buffer pad is detachably connected to the side of the shape memory alloy adjustment plate away from the electric push rod. The electric push rod is signal-connected to the control module. The control module determines the head shape contour based on the pressure data collected by the pressure sensing unit and drives the electric push rod to shape the shape memory alloy adjustment plate to fit the head contour evenly.

[0014] Furthermore, the quick-release module includes a male buckle, a female buckle, and an electromagnetic drive assembly. The male buckle and the female buckle are fixed on both sides of the housing. The male buckle has a built-in elastic locking tongue, and the female buckle has a lock hole corresponding to the elastic locking tongue and an unlocking sensor. The unlocking sensor is used to detect the connection status of the buckle locking tongue and the lock hole in real time. The electromagnetic drive assembly and the unlocking sensor are both electrically connected to the control module. When the control module receives a disassembly command, the control module controls the electromagnetic drive assembly to be de-energized, and the elastic locking tongue automatically retracts.

[0015] Furthermore, the drainage tube protection module includes an elastic buffer sleeve, a pressure compensation airbag, and a flow warning device; the elastic buffer sleeve has a drainage tube positioning groove along the axial direction inside, and a pressure compensation airbag is wrapped around the outside of the elastic buffer sleeve. The pressure compensation airbag is connected to an air pump, and the air pump is connected to the control module.

[0016] When the zone pressure regulating module adjusts the pressure, the control module synchronously controls the air pump to inflate or deflate the pressure compensation airbag to counteract the pressure change of the elastic band on the drainage tube; when the flow sensor detects an abnormal flow rate, the flow warning device is triggered to provide an alert, and at the same time, the control module adjusts the air pressure of the pressure compensation airbag through the air pump.

[0017] Furthermore, the shell includes an inner layer and an outer layer, which are detachably connected. The shell has an openable observation window corresponding to the wound area, and the edge of the observation window is provided with a silicone sealing ring.

[0018] Furthermore, the control module is also connected to an audible and visual warning component, which includes an indicator light and a buzzer. When any data collected by the monitoring module exceeds a preset threshold, the audible and visual warning component emits different signals according to the type of anomaly:

[0019] When pressure data is abnormal, the indicator light flashes red and the buzzer emits a high-frequency warning sound; when skin humidity data is abnormal, the indicator light flashes yellow and the buzzer emits a medium-frequency warning sound; when drainage tube flow data is abnormal, the indicator light flashes blue and the buzzer emits a low-frequency warning sound.

[0020] Furthermore, ventilation channels are provided between the inner and outer layers, and several heat dissipation holes are provided on both the inner and outer layers.

[0021] The above approach has the following beneficial effects:

[0022] 1. This solution utilizes a triangular stable fixation structure formed by the linkage of a zoned pressure adjustment module and an anti-slip anchoring module. Combined with the shape-memory alloy adjustment plate of the head shape adaptive module, it achieves precise fit for different head circumferences and irregular head shapes, effectively preventing device displacement or localized pressure concentration. Compared to traditional single-size bandages and simple elastic head covers, which rely solely on manual binding or elastic contraction for fixation, this solution offers a narrow range of fit and cannot adapt to irregular head shapes after craniocerebral surgery or decompression surgery. This can easily lead to risks such as bleeding, fluid leakage, wound traction, or pressure on defect areas. This solution significantly improves fixation stability and treatment safety.

[0023] 2. This solution integrates monitoring and control modules, collecting real-time data on pressure, skin moisture, and drainage tube flow. It uses audible and visual warning components to differentiate abnormalities and automatically adjusts various functional modules. Furthermore, the dynamic fit design with ventilation channels, heat dissipation holes, and silicone anti-slip pads optimizes wearing comfort. Compared to traditional head fixation devices, which lack any monitoring or automatic adjustment functions, relying entirely on medical staff's experience to judge pressure, and whose skin-contact materials lack breathability and sweat-wicking design, prolonged wear can easily lead to skin redness, itching, and even infection. This solution significantly reduces the incidence of skin discomfort and improves treatment compliance.

[0024] 3. This solution simplifies clinical procedures through its electromagnetic snap-on structure for quick-release modules, openable observation windows, and pressure compensation design for drainage tube protection modules. Dressing changes are quick, and routine wound observation does not require complete disassembly of the device. Compared to traditional bandages and Velcro caps, which require wrapping or unwrapping 3-5 times for dressing changes, are time-consuming and prone to wound contact and drainage tube traction, and whose adhesive properties weaken with repeated disassembly, necessitating frequent replacements and increased medical costs, this solution reduces the workload of medical staff, minimizes the risk of secondary wound damage and drainage failure, and reduces medical consumable waste.

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

[0034] The following detailed description illustrates the specific implementation method:

[0035] Example 1:

[0036] As attached Figures 1 to 4 As shown: A head dressing fixation device includes a main body, a housing 1 for conforming to the contour of the head, an elastic band 2 installed inside the housing 1, a quick-release module 6 for quick removal and avoiding pulling on the wound, and a head shape adaptive module for adapting to irregular head shapes. The quick-release module 6 is installed at both ends of the housing 1, and the head shape adaptive module is distributed at the positions of the housing 1 corresponding to the forehead, occiput, and both sides of the temples. The housing 1 has several mounting cavities 101, in which pressure adjustment is achieved. The device includes a zoned pressure regulating module adapted to different head circumferences and intracranial pressure control needs, an anti-slip anchoring module to enhance the friction between the shell 1 and the scalp to prevent the device from shifting during patient movement, and a drainage tube protection module to accommodate and protect the drainage tube from pressure, folding, and pulling. The zoned pressure regulating module is symmetrically installed on the shell 1 at the corresponding positions on the forehead and occipital region. The anti-slip anchoring module is located on the inner side of the shell 1 corresponding to the temporal region. The drainage tube protection module extends along the edge of the shell 1 and is elastically connected to the shell 1. The zoned pressure regulating module and the anti-slip anchoring module work together to form a triangular stable fixing structure.

[0037] The housing 1 is also equipped with a monitoring module for real-time monitoring of head stress, skin condition and drainage tube patency. The monitoring module is connected to a control module, which is connected to the zone pressure adjustment module, anti-slip anchoring module and head shape adaptive module. The control module is used to automatically adjust the zone pressure adjustment module based on the pressure data, skin humidity data and drainage tube flow data collected by the monitoring module.

[0038] The monitoring module includes a pressure sensing unit, a skin condition monitoring unit, and a drainage monitoring unit. The pressure sensing unit includes a pressure sensor for collecting the contact pressure between the zoned pressure regulating module and the head, and the pressure sensor is attached to the surface of the zoned pressure regulating module. The skin condition monitoring unit includes a humidity sensor for detecting the accumulation of sweat on the scalp, and the humidity sensor is embedded inside the anti-slip anchoring module. The drainage monitoring unit includes a flow sensor for monitoring the flow rate of the drainage fluid, and the flow sensor is housed inside the drainage tube protection module.

[0039] The zoned pressure regulating module includes an electric regulating component, which includes a driving component. The driving component is fixedly connected to the mounting cavity 101. In this embodiment, the driving component is a motor. The output shaft of the driving component is coaxially fixedly connected to a worm gear 3. The worm gear 3 meshes with a worm 4. One end of the worm 4 is wound and connected to an elastic band 2 that passes through the mounting cavity 101. The driving component is signal-connected to the control module. The control module drives the driving component to rotate forward or backward according to the pressure data collected by the pressure sensing unit. The worm gear 3 and the worm 4 drive the elastic band 2 to contract or relax.

[0040] The anti-slip anchoring module includes an adaptive deformation seat, a silicone anti-slip pad, and a power component. The adaptive deformation seat has an arc-shaped hollow structure, and the power component is embedded inside the adaptive deformation seat. In this embodiment, the power component is an electric cylinder, and the power component is electrically connected to the control module. The silicone anti-slip pad is detachably connected to the inner side of the adaptive deformation seat. The surface of the silicone anti-slip pad is provided with a honeycomb anti-slip texture and avoidance holes corresponding to the humidity sensor. When the humidity sensor detects excessive sweat, the control module drives the silicone anti-slip pad to deform, so that the silicone anti-slip pad dynamically adheres to the scalp.

[0041] The head shape adaptive module includes several sets of detachable elastic adjustment units. Each elastic adjustment unit includes a shape memory alloy adjustment piece 5. The shape memory alloy adjustment piece 5 is embedded along the length of the inner wall of the housing 1, and an electric push rod is installed between the shape memory alloy adjustment piece 5 and the housing 1. A buffer pad is detachably connected to the side of the shape memory alloy adjustment piece 5 away from the electric push rod. The electric push rod is connected to the control module. The control module determines the head shape contour based on the pressure data collected by the pressure sensing unit and drives the electric push rod to shape the shape memory alloy adjustment piece 5 to fit the head contour evenly.

[0042] The quick-release module 6 includes a male buckle 601, a female buckle 7, and an electromagnetic drive assembly. The male buckle 601 and the female buckle 7 are fixed on both sides of the housing 1. The male buckle 601 has a built-in elastic locking tongue 602. The female buckle 7 has a lock hole 701 corresponding to the elastic locking tongue 602 and an unlocking sensor. The unlocking sensor is used to detect the connection status of the buckle locking tongue and the lock hole 701 in real time. The electromagnetic drive assembly and the unlocking sensor are both electrically connected to the control module. When the control module receives a disassembly command, the control module controls the electromagnetic drive assembly to be de-energized, and the elastic locking tongue 602 automatically retracts.

[0043] The drainage tube protection module includes an elastic buffer sleeve, a pressure compensation airbag, and a flow warning device. The elastic buffer sleeve has an axially positioned drainage tube groove inside, and a pressure compensation airbag is wound around the outside of the elastic buffer sleeve. The pressure compensation airbag is connected to an air pump, which is connected to the control module. When the zone pressure regulating module adjusts the pressure, the control module simultaneously controls the air pump to inflate or deflate the pressure compensation airbag, counteracting the pressure changes of the elastic band 2 on the drainage tube. When the flow sensor detects an abnormal flow rate, the flow warning device triggers an alert, and the control module simultaneously adjusts the pressure of the pressure compensation airbag via the air pump.

[0044] The specific implementation process is as follows: Based on the head circumference of the patient after routine adult craniocerebral surgery, select a suitable device body, ensuring that the drainage tube positioning groove faces the drainage tube outlet direction. Apply the dressing to the affected area, then fit the shell 1 to the contour of the patient's head, aligning the zoned pressure adjustment module with the key pressure points on the forehead and occipital region, and ensuring that the silicone anti-slip pad of the anti-slip anchoring module fits against the temporal scalp. The drainage tube passes through the drainage tube positioning groove of the drainage tube protection module, and both ends are initially fixed by the limiting structure of the drainage tube positioning groove. Press the quick-release modules 6 at both ends of the shell 1, causing the elastic locking tongue 602 of the male buckle 601 to insert into the locking hole 701 of the female buckle 7. After the unlocking sensor detects that the locking is in place, it sends a fixing completion signal to the control module, completing the initial wearing.

[0045] After wearing the device, the control module automatically activates the monitoring module. The pressure sensor collects real-time contact pressure data from the forehead, occiput, and temples; the humidity sensor detects scalp sweat accumulation; and the flow sensor monitors the drainage fluid flow rate. Initially, if the pressure sensor detects forehead pressure exceeding the control module's preset pressure threshold, skin humidity below the humidity threshold, or drainage flow exceeding the minimum flow threshold, the control module processes the data and determines that the forehead pressure is excessive, while other parameters remain normal.

[0046] The control module sends a reverse signal to the drive component (motor) of the zoned pressure regulating module. The motor output shaft drives the worm gear 3 to rotate, and the worm gear 3 meshes with the worm 4 to rotate synchronously. The elastic band 2 wrapped around one end of the worm 4 slowly relaxes, releasing the tension on the forehead side. At the same time, the control module sends an adaptation signal to the power component (electric cylinder) of the anti-slip anchoring module. The electric cylinder drives the adaptive deformation seat to deform slightly, causing the silicone anti-slip pad to adhere to the pressure area of ​​the temporal region. The honeycomb anti-slip texture on its surface increases the friction with the scalp, and the gradual structural design prevents local pressure concentration. The pressure sensor provides real-time feedback of pressure data. When the detected forehead pressure drops to within the preset threshold range, the control module sends a stop signal. The motor and electric cylinder stop working, and the triangular stable fixing structure formed by the zoned pressure regulating module and the anti-slip anchoring module ensures that the device does not shift, while accurately controlling intracranial pressure.

[0047] During the data acquisition process, the pressure sensor simultaneously detects the pressure distribution along the head contour. If a slight pressure unevenness is detected in the occipital region, the control module determines that the head shape is slightly irregular and sends an adjustment signal to the electric actuator of the head shape adaptation module. The electric actuator extends and pushes the shape memory alloy adjustment piece 5 to conform to the contour of the occipital region, undergoing adaptive deformation. The cushioning pad on the surface of the shape memory alloy adjustment piece 5 makes flexible contact with the scalp, filling in slight depressions and ensuring that the housing 1 is evenly stressed. The pressure sensor continuously monitors the pressure distribution. When the pressure distribution uniformity reaches a preset pressure threshold, the electric actuator stops moving, and the shape memory alloy adjustment piece 5 maintains its shaped state, ensuring wearing comfort.

[0048] During the tension adjustment process of the zoned pressure regulating module, the control module simultaneously sends a pressure compensation signal to the air pump of the drainage tube protection module. Based on the tension change of the elastic band 2, the air pump inflates the pressure compensation airbag with an appropriate amount of gas, matching the airbag's expansion amplitude with the pressure change of the elastic band 2. This counteracts the squeezing force of the elastic band 2 on the drainage tube, ensuring unobstructed and pressure-free drainage within the drainage tube positioning groove. A flow sensor monitors the drainage fluid flow rate in real time. If the drainage fluid flow rate briefly exceeds the minimum flow threshold during wear, the control module determines it as normal fluctuation and requires no additional adjustment. If the flow rate remains below the minimum flow threshold, the flow warning device triggers an audible and visual alert, and the control module simultaneously controls the air pump to fine-tune the pressure compensation airbag pressure, alleviating the flow resistance of the drainage fluid.

[0049] The monitoring module continuously collects data and transmits it to the control module, which compares the data every 5 seconds. If the skin humidity sensor detects that the scalp humidity has risen to the minimum humidity threshold, the control module determines that there is only a small amount of sweat accumulation and does not need to activate the deformation function of the anti-slip anchoring module. Natural heat dissipation is achieved solely through the breathable structure of the device itself. If the humidity continues to rise to the maximum humidity threshold, the control module drives the electric cylinder of the anti-slip anchoring module to actuate again, causing the silicone anti-slip pad to rise slightly, creating a tiny breathable gap. At the same time, the humidity sensor provides real-time feedback data. When the humidity drops to the humidity threshold, the silicone anti-slip pad returns to its attached state.

[0050] When dressing needs to be changed, medical staff first send a reverse signal to the motor of the zoned pressure regulating module via the control module, driving the elastic band 2 to release tension and avoid pulling on the wound during removal. Then, a power-off signal is sent to the electromagnetic drive component of the quick-release module 6. After the electromagnetic drive component is de-energized, the elastic locking tongue 602 built into the male buckle 601 automatically retracts, separating from the locking hole 701 of the female buckle 7. Once the unlocking sensor detects that the separation is complete, it sends a disassembly completion signal to the control module, allowing medical staff to easily remove the housing 1 and change the dressing. After the change is complete, the device is re-worn and locked via the quick-release module 6. The control module automatically initiates a new adaptation process to ensure the device quickly returns to a stable and fixed state.

[0051] Example 2:

[0052] The difference from Embodiment 1 is that the shell 1 includes an inner layer and an outer layer, which are detachably connected. The shell 1 is provided with an openable observation window corresponding to the wound area, and a silicone sealing ring is provided at the edge of the observation window.

[0053] The specific implementation process is as follows: The inner layer is fitted to the contour of the patient's head, aligning the zoned pressure adjustment module with the pressure points on the forehead and occipital region. The silicone anti-slip pad of the anti-slip anchoring module is fitted to the temporal scalp. The drainage tube passes through the drainage tube positioning groove of the drainage tube protection module and is initially fixed by the limiting structure. The observation window is closed, and the silicone sealing ring is tightly fitted to the shell 1 to ensure the protection of the wound area.

[0054] When routine wound observation is required, there is no need to disassemble the entire device. Medical staff can directly open the observation window corresponding to the wound area on the housing 1 to check the wound healing status, bleeding, and exudation. The silicone sealing ring maintains the protection of the surrounding area during observation, preventing contaminants from entering. After observation, the observation window is closed, and the silicone sealing ring re-adheres tightly onto the housing 1, restoring complete protection. This significantly improves clinical observation efficiency and avoids the wound traction risks associated with traditional complete disassembly.

[0055] Example 3:

[0056] The difference from Embodiment 2 is that the control module is also connected to an audible and visual warning component, which includes an indicator light and a buzzer. When any data collected by the monitoring module exceeds a preset threshold, the audible and visual warning component emits different signals according to the type of abnormality:

[0057] When pressure data is abnormal, the indicator light flashes red and the buzzer emits a high-frequency warning sound; when skin humidity data is abnormal, the indicator light flashes yellow and the buzzer emits a medium-frequency warning sound; when drainage tube flow data is abnormal, the indicator light flashes blue and the buzzer emits a low-frequency warning sound.

[0058] The specific implementation process is as follows: Pressure sensors collect pressure data from various areas of the head in real time. Initially, if the pressure data in the occipital region exceeds the preset pressure threshold, the skin humidity data is below the humidity threshold, or the drainage flow data is above the minimum flow threshold, the control module determines that the pressure data is abnormal and immediately triggers the audible and visual warning component: a red light flashes, a buzzer emits a high-frequency warning sound, and a control signal is simultaneously sent to the zoned pressure regulation module. The motor of the zoned pressure regulation module reverses, driving the elastic band 2 to loosen through the worm gear 3 and worm 4. The pressure sensor continues to provide feedback data until the occipital pressure drops to within the pressure threshold range. At this point, the control module sends a signal, the audible and visual warning component stops working, the red light goes out, and the buzzer is silenced.

[0059] If the skin humidity sensor detects that the scalp humidity data has risen above the humidity threshold, the control module determines that the skin humidity data is abnormal and triggers the audible and visual warning component: a yellow light flashes and a buzzer emits a mid-frequency warning sound. Simultaneously, the control module drives the electric cylinder of the anti-slip anchoring module, causing the silicone anti-slip pad to rise slightly, creating a breathable gap and accelerating sweat evaporation. The humidity sensor provides real-time humidity data; when the humidity data drops to the humidity threshold, the control module sends a signal, the audible and visual warning component stops issuing warnings, and the silicone anti-slip pad returns to its attached state.

[0060] If, during observation, the drainage fluid flow rate slows down and the flow sensor detects that the flow rate has dropped below the minimum flow threshold, the control module determines that the drainage tube flow data is abnormal and triggers the audible and visual warning component: a blue light flashes and a buzzer emits a low-frequency warning sound. Simultaneously, the control module adjusts the pressure of the airbag via an air pump to compensate until the drainage flow rate returns to the flow threshold, at which point the warning component stops operating.

[0061] Example 4:

[0062] The difference from Embodiment 3 is that ventilation channels are provided between the inner and outer layers, and several heat dissipation holes are provided on both the inner and outer layers.

[0063] The specific implementation process is as follows: The ventilation channels between the inner and outer layers, along with the heat dissipation holes on both layers, form airflow channels, accelerating sweat evaporation; simultaneously, the control module drives the electric cylinder of the anti-slip anchoring module to actuate, causing the silicone anti-slip pad to rise slightly, further enhancing the ventilation effect. The ventilation channels and heat dissipation holes continuously maintain natural ventilation, preventing the skin from becoming stuffy and damp.

[0064] 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.
