Description

Technical Field

[0002] In medical monitoring environments, real-time detection of accidental falls is a critical safety requirement for patients, especially the elderly, post-operative patients, or those with limited mobility. Currently, common fall detection methods mainly rely on video surveillance systems and independent devices such as pressure-sensing pads laid in specific areas.

[0003] However, in practice, it has been found that when the above-mentioned methods are used for fall detection, video surveillance poses risks of privacy leaks and blind spots. The easily shifting edges of the pressure sensor pad not only bring new tripping risks, but also cannot withstand the repeated crushing of high-frequency disinfection and equipment such as work beds and wheelchairs. At the same time, the pressure sensor pad is prone to absorbing water, which can lead to the growth of bacteria inside, and there are often technical problems with low system reliability.

[0024] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Figure 1 This is a schematic diagram of the structure of an integrated protective fall detection floor system for a medical monitoring environment, according to some embodiments of the present disclosure. Figure 1It includes a finishing layer 1, a flexible balancing layer 2, a support plate 3, adjustable support feet 4, an array of mounting holes 5, and a placement groove 6.

[0026] Figure 2 This is a schematic diagram of the internal testing structure of an integrated protective fall detection floor system for a medical monitoring environment, according to some embodiments of this disclosure.

[0027] In some implementations, the aforementioned integrated protective fall detection floor system for medical monitoring environments includes: an adjustable support unit, floor units, and a control device. The adjustable support unit may include a support plate 3 and adjustable support feet 4. The support plate 3 may be a rigid material with sufficient structural strength and flatness, such as a plate made of metal, high-density composite material, or engineering plastic. The adjustable support feet 4 may be support members installed at the bottom of the support plate 3, with adjustable height. For example, the adjustable support feet 4 may include a fixing part and an adjusting part. The fixing part may be a rod with one end embedded in the support plate 3 and the other end having external threads. The adjusting part may be a base with internal threads that contacts the ground. The leveling of the support plate 3 can be achieved by rotating the adjusting rod in the base. Multiple adjustable support units may be laid in an array on the ground to form a support plane, with an adjustable support foot 4 forming an air gap between the support plate 3 and the ground. This air gap not only provides concealed and protected space for pipes and wiring but also reduces the safety hazards caused by exposed wiring. At the same time, the aforementioned elevated floor can also reduce noise transmission, creating a quieter and more comfortable atmosphere for the medical environment.

[0028] In some embodiments, the floor unit may include, from bottom to top, a flexible balancing layer 2, a pressure sensing layer, and a finishing layer 1. The flexible balancing layer 2 may be a PET board, capable of replacing self-leveling compound to increase the system's flatness. Simultaneously, the flexible balancing layer 2 also possesses cushioning properties, reducing the impact of falls and minimizing injuries. The pressure sensing layer may include a pressure sensor array and a data acquisition unit (not shown in the figures). Each pressure sensor in the pressure sensor array may be a thin-film pressure sensor or a strain gauge pressure sensor, characterized by high sensitivity and rapid response, capable of capturing pressure changes in real time. The data acquisition unit may be an electronic circuit module with data transmission capabilities. The finishing layer 1 may be a flat board surface that can be directly used as a walking surface. For example, the finishing layer 1 may be ceramic tile or medical-grade PVC (Polyvinyl chloride) flooring. Specifically, refer to... Figure 2 , Figure 2 This is a schematic diagram of the internal testing structure for an integrated protective fall detection floor system used in medical monitoring environments. Figure 2One end of the middle finishing layer 1 is ceramic tile, and the other end is medical-grade PVC flooring. This is only used as an example to demonstrate the diversity of materials used in finishing layer 1. Medical-grade PVC flooring has excellent wear resistance, slip resistance, and easy-to-clean properties, meeting the high standards required for flooring materials in medical environments. The above flooring units can be prefabricated in the factory, with the flexible balancing layer 2, pressure-sensing layer, and finishing layer 1 precisely assembled and fixed according to design requirements, ensuring a tight and stable connection between each layer.

[0029] In some embodiments, the flexible balancing layer 2 may be provided with a placement groove 6, and the pressure sensing layer may be disposed within the placement groove 6. The size of the placement groove 6 may be adapted to the pressure sensing layer, providing a stable and precise installation position for the pressure sensing layer. The finishing layer 1 may be laid on top of the flexible balancing layer 2. The pressure sensor array may contact the bottom surface of the finishing layer 1, thereby more accurately capturing pressure changes. Multiple floor units laid in an array on the supporting plane can form a complete floor surface, achieving full coverage of the entire room.

[0030] In some embodiments, the pressure sensor array is configured to detect pressure data in real time, which may include the pressure values ​​detected by each pressure sensor. The pressure sensor array can communicate with the data acquisition unit. The data acquisition unit is configured to transmit the pressure data to the control device in real time. The control device can be an independent processing unit, such as an embedded computer or server. The control device can set coordinate data for each floor unit, which can represent the room number location of each floor unit, facilitating precise management of different areas. The control device can communicate with the hospital's monitoring center to promptly notify medical staff when a fall is detected. Specifically, the control device can analyze the pressure data to determine if a fall has occurred. Pressure changes are relatively gradual during normal walking, but drastic during a fall. Furthermore, pressure distribution is more concentrated during normal walking or standing, and adjacent floor units continuously detect pressure data after a fall. The drastic pressure changes and the continuous detection of pressure data by adjacent floor units can confirm the occurrence of a fall. When a fall is detected, the control device can quickly trigger an alarm mechanism, sending the room number of the detected person to medical personnel via sound or network signal, so that medical personnel can arrive at the scene in time for rescue. The control device can communicate with the data acquisition units of each of the aforementioned floor units via control lines. These control lines can be cables (such as network cables or bus cables) used to transmit power and data between the data acquisition units and the control device. The control lines can be laid in the aforementioned elevated floor, improving the safety and concealment of the control wiring, facilitating later maintenance and repair, thereby extending the service life of the control wiring and reducing the system failure rate.

[0031] Optionally, the aforementioned support plate 3 may be provided with a mounting hole array 5, which may be threaded holes evenly distributed on the support plate 3. Each mounting hole in the mounting hole array 5 may be provided with internal threads. The aforementioned adjustable support foot 4 may include a fixed base and a leveling bolt. The aforementioned fixed base may be a hollow structure, with one end having an external thread that mates with the aforementioned mounting hole, and the other end having an internal thread. A limiting baffle may be provided in the middle of the aforementioned fixed base, which can limit the installation depth of the aforementioned fixed base to prevent the aforementioned fixed base from being excessively screwed into the aforementioned support plate 3, causing the aforementioned support plate 3 to sink. One end of the aforementioned leveling bolt may have an external thread that mates with the aforementioned fixed base, and the end may have a groove in the shape of an "I", "+", or internal hexagon, etc., to facilitate rotational adjustment using tools. The other end of the aforementioned leveling bolt may be in direct contact with the ground, and the end may be flat to increase the contact area with the ground and improve stability. At the same time, the end may also have the same groove as the other end, to facilitate engagement of the aforementioned leveling bolt with the aforementioned fixed base using tools. Specifically, multiple fixed bases can be installed in the mounting hole array 5. Then, leveling bolts can be screwed into the fixed bases using a tool. Next, the bearing plate 3 and adjustable support feet 4 can be placed on the ground. Finally, the leveling bolts can be adjusted using a tool to move up and down within the fixed bases, thereby adjusting the flatness of the bearing plate 3.

[0032] Optionally, the bottom of the leveling bolt is provided with an anti-slip pad. This anti-slip pad can be made of rubber, possessing good anti-slip and wear-resistant properties, maintaining a stable anti-slip effect during long-term use. Simultaneously, the surface of the anti-slip pad can be designed with raised anti-slip textures to further increase friction with the ground, ensuring the leveling bolt is not prone to slippage under external force. The anti-slip pad can have a side-insertion structure, with a groove provided on its side, allowing the leveling bolt to slide into and lock into place. This ensures a tighter connection between the anti-slip pad and the leveling bolt, preventing detachment during use.

[0033] Optionally, the aforementioned support plate 3 may also be provided with a first wire hole, and the aforementioned flexible balancing layer 2 may be provided with a second wire hole corresponding to the position of the aforementioned first wire hole. Both the aforementioned first wire hole and the aforementioned second wire hole can be through holes that allow the aforementioned control lines to pass through, so that the aforementioned control lines can communicate with the aforementioned data acquisition device by passing through the aforementioned second wire hole and the aforementioned first wire hole.

[0034] Optionally, the upper surface of the bearing plate 3 may be provided with a positioning pin, and the bottom surface of the flexible balancing layer 2 may be provided with a positioning hole. The positioning pin and the positioning hole can be fitted with a clearance, which can ensure the smoothness of installation, reduce the difficulty of operation during installation, ensure the positional accuracy after installation, prevent the flexible balancing layer 2 from sliding relative to the bearing plate 3, further enhance the stability and durability of the floor system, and facilitate subsequent disassembly and maintenance.

[0035] Optionally, the flexible balancing layer 2 and the supporting plate 3, the pressure sensing layer and the flexible balancing layer 2, and the finishing layer 1 and the pressure sensing layer can be bonded and fixed together using an adhesive. The adhesive can be a medical-grade adhesive, possessing high strength, aging resistance, and corrosion resistance, ensuring a firm connection between the layers and preventing long-term detachment. This adhesive is not only environmentally friendly and non-toxic, meeting the requirements of medical environments, but also effectively resists the erosion of common disinfectants and cleaning agents in medical environments, ensuring the stability and reliability of the system.

[0036] Optionally, the inner walls of both the first and second wire holes can be fitted with insulating sleeves. These insulating sleeves can be made of rubber or plastic, possessing good insulation properties. This reduces the risk of insulation damage caused by friction between the control circuit and the edge of the wire hole when the circuit passes through it. Simultaneously, it provides some protection for the control circuit, reducing wear and extending its service life.

[0037] Optionally, the adjustable support feet 4 can be fixedly connected to the support plate 3 and the ground respectively using expanding foam. The leveling bolts of the adjustable support feet 4 can be hollow to facilitate the flow of expanding foam. Specifically, after the support plate 3 is leveled, expanding foam can be injected through the mounting hole array 5. The expanding foam can flow to the ground through the hollow structure of the leveling bolts. After the expanding foam cures, a stable connection can be achieved between the adjustable support feet 4, the support plate 3, and the ground. This connection method not only enhances the overall structural strength of the overhead adjustment unit but also reduces loosening and displacement caused by long-term use or external forces, ensuring the flatness and stability of the system. At the same time, the filling of expanding foam and the setting of the anti-slip pads can also play a certain role in sound insulation and vibration reduction, improving the comfort of use in medical environments.

[0038] Optionally, the sides of two adjacent support plates 3 that are in contact can be provided with a vertical splicing structure. One support plate 3 may have a downwardly extending hook on its side, and the end of the hook may have an inwardly extending limiting protrusion. The other support plate 3 may have an upwardly opening groove that fits the hook, and the groove may have a limiting groove that engages with the limiting protrusion. The hook and groove constitute the vertical splicing structure, allowing the hook to be inserted into the groove and the limiting protrusion into the limiting groove. When splicing the two support plates 3, simply align the hook of one support plate 3 with the groove of the other support plate 3, then press downwards to insert the hook into the groove, while simultaneously inserting the limiting protrusion into the limiting groove, thus achieving a stable splicing of the two support plates 3. The above-mentioned vertical splicing structure is not only easy and quick to install, which can greatly improve construction efficiency, but also has high connection strength after splicing, which can effectively prevent the bearing plate 3 from separating or misaligning during use, thus ensuring the stability and reliability of the above-mentioned support plane.

[0039] In addressing the aforementioned technical problems through the adoption of technical solutions, the application scenario of this technical solution—a rehabilitation center hydrotherapy room—often presents the following additional technical challenges: In a rehabilitation center hydrotherapy room, the floor is frequently exposed to moisture, leading to dampness and slipperiness. Gaps between floorboards are difficult to clean and easily breed bacteria in the humid environment. Liquids can also easily seep through these gaps, causing corrosion of metal components and electrical insulation failure, frequently posing significant safety hazards. Considering the following requirements for this application scenario: adaptability to a humid environment and reduction of bacterial growth, we have decided to adopt the following solution: Optionally, the system may further include an antibacterial unit and a sealing and protective unit. The antibacterial unit may include an antibacterial board disposed at the bottom of the finishing layer 1, and an anti-mildew and antibacterial coating applied to the surface of the flexible balancing layer 2 and the surface of the supporting plate 3. The upper surface of the finishing layer 1 may be a frosted surface, which increases friction and reduces the risk of slipping. The antibacterial board may be a board with internally distributed slow-release antibacterial microcapsules; for example, the antibacterial board may be a wooden board using slow-release antibacterial microcapsules as a functional filler. The slow-release antibacterial microcapsules can slowly release antibacterial components (such as nano-silver ions or organosilicon quaternary ammonium salt antibacterial agents) upon contact with moisture, effectively inhibiting the growth of mold, bacteria, and other microorganisms. When liquid seeps down along the gap between the two floor units, it comes into contact with the antibacterial board. The wooden antibacterial board can absorb a certain amount of moisture, and the slow-release antibacterial microcapsules slowly release antibacterial components upon contact with moisture, effectively inhibiting the growth of mold, bacteria, and other microorganisms. The antibacterial plate has a groove corresponding to the pressure sensor array, and the bottom of the decorative layer 1 has a protrusion corresponding to the pressure sensor array. The pressure sensor array contacts the protrusion, allowing the pressure sensors to directly contact the decorative layer 1, reducing the force transmission path and enabling more accurate sensing of pressure changes. This facilitates detection of falls in slippery spa rooms. The groove design of the antibacterial plate also facilitates installation, ensuring a tight fit between the antibacterial plate and the overall structure. Both the pressure sensor array and the data acquisition unit can be coated with a waterproof coating. This waterproof coating can be made of waterproof materials such as silicone or polyurethane, providing excellent waterproof performance and effectively preventing moisture from penetrating the pressure sensor array and data acquisition unit. This reduces the risk of short circuits or component damage caused by humid environments, ensuring stable system operation even in high humidity conditions. The anti-mildew and antibacterial coating can be an epoxy resin composite coating, which can be evenly applied to the surfaces of the flexible balance layer 2 and the support plate 3 by spraying or brushing, forming a dense protective film. The aforementioned epoxy resin composite coating can be a composite coating containing nano-silver ions and antifungal agents, possessing excellent antifungal and antibacterial properties. It can form a dense protective film, effectively isolating moisture and mold erosion, extending the system's service life, and ensuring the hygiene and safety of the medical environment. The aforementioned sealing and protection unit can include medical-grade sealing strips installed at the joints between adjacent floor units and waterproof sealing rings installed at the control circuit interfaces. The aforementioned medical-grade sealing strips can be made of silicone, possessing good elasticity and weather resistance, and can tightly adhere to the joints between adjacent floor units, effectively preventing moisture and liquid from seeping down along the gaps. Simultaneously, the silicone medical-grade sealing strips also have good antibacterial properties, reducing bacterial growth in the gaps.The aforementioned medical-grade sealing strip has a double trapezoidal cross-section, which allows it to better fill the joints when compressed by the floor units on both sides, creating a tighter seal and preventing liquid seepage. Furthermore, the double trapezoidal structure increases the contact area between the sealing strip and the floor unit, improving friction and preventing it from detaching during use. When the medical-grade sealing strip is damaged, moisture will seep through the gap and first contact the antibacterial board. The antibacterial board absorbs the moisture and slowly releases antibacterial components, effectively inhibiting the growth of mold, bacteria, and other microorganisms, thus saving valuable time for subsequent maintenance and repair. During maintenance and repair, the damaged medical-grade sealing strip can be removed first. Then, a tool (such as a suction cup) can be used to lift the finishing layer 1 to observe whether the antibacterial board is extensively wetted. If the antibacterial board is not extensively wetted, simply replace it with a new medical-grade sealing strip. If the antibacterial board is extensively wetted, it needs to be replaced with a new antibacterial board. The aforementioned waterproof sealing ring can be made of fluororubber, which has excellent chemical corrosion resistance and high-temperature resistance. Even in environments with prolonged contact with moisture and potentially present chemicals such as disinfectants, it can still maintain good sealing performance. This waterproof sealing ring can be tightly fitted onto the interface of the control circuit, effectively preventing moisture and liquid from entering through the interface. This avoids safety hazards such as short circuits and insulation failure caused by water ingress, ensuring the electrical safety and stable operation of the entire floor system.

[0040] The above-described technical solution, as an inventive point of this disclosure, solves the technical problem of "in the hydrotherapy room of a rehabilitation center, the floor is prone to dampness and slipperiness due to prolonged contact with moisture. Gaps between floorboards are difficult to clean and easily breed bacteria in a damp environment. Liquids can also easily seep through these gaps, leading to corrosion of metal parts and failure of electrical insulation, resulting in significant safety hazards." The factors contributing to these significant safety hazards are often as follows: in the hydrotherapy room of a rehabilitation center, the floor is prone to dampness and slipperiness due to prolonged contact with moisture. Gaps between floorboards are difficult to clean and easily breed bacteria in a damp environment. Liquids can also easily seep through these gaps, leading to corrosion of metal parts and failure of electrical insulation, frequently resulting in significant safety hazards. Solving these factors can reduce the safety hazards. To achieve this effect, the integrated protective fall detection floor system for medical monitoring environments disclosed herein effectively adapts to the humid environment of a rehabilitation center's spa room by incorporating antibacterial and sealed protective units. This reduces bacterial growth, prevents metal corrosion and circuit insulation failure caused by liquid seepage, significantly reduces safety hazards, and improves the reliability and safety of the floor system.

[0041] In addressing the aforementioned technical problems through the adoption of technical solutions, the application scenario of this technical solution—the equipment rinsing area of ​​a rehabilitation center's hydrotherapy room—often presents the following additional technical challenges: In this area, the use of pressurized water containing disinfectant to rinse wheelchairs, stretchers, and other equipment leads to liquid accumulation, increasing the risk of liquid seeping into the gaps between floor units. Simultaneously, the sealing strips at the floor joints are prone to wear, deformation, and even detachment due to frequent pressure from wheelchairs and stretchers, affecting the sealing effect and causing liquid seepage. Furthermore, the disinfectant solution alters the pH level of the environment, increasing the risk of bacterial growth. Considering the following requirements for this application scenario: withstanding high-pressure water jets, rapid drainage, adaptability to pressure-resistant sealing, and adaptability to changes in environmental pH, we have decided to adopt the following solution: Optionally, the aforementioned sustained-release antibacterial microcapsules can employ an acid-base responsive release mechanism. When a liquid containing a disinfectant (such as sodium hypochlorite) comes into contact with the antibacterial plate, the disinfectant alters the pH of the contact area, triggering the release mechanism of the sustained-release antibacterial microcapsules. This allows the antibacterial components to be released more precisely into areas affected by the disinfectant, effectively inhibiting bacterial growth caused by the disinfectant altering the pH of the environment and enhancing the antibacterial effect. The aforementioned medical-grade sealing strip can be embedded with reinforcing fibers. These reinforcing fibers can be high-strength fiber materials such as glass fiber or carbon fiber, and can be distributed in a mesh pattern. This enhances the mechanical strength and wear resistance of the medical-grade sealing strip, ensuring structural integrity and stability even under frequent pressure from wheelchairs, stretchers, and other equipment, preventing wear, deformation, or detachment. Simultaneously, the reinforcing fibers also improve the elastic recovery performance of the medical-grade sealing strip, allowing it to quickly return to its original shape after compression, maintaining a good sealing effect. The aforementioned reinforcing fibers can be blended and cured with the aforementioned silicone material to form a composite structure. This not only enhances the strength of the sealing strip but also improves its tear resistance, further extending the service life of the medical-grade sealing strip. The upper and lower trapezoids of the aforementioned double trapezoidal structure can be connected by an arc-shaped transition section. This allows for a more uniform stress distribution when the medical-grade sealing strip is subjected to external pressure, reducing the possibility of damage due to stress concentration. Simultaneously, the arc-shaped transition section increases the adhesion between the medical-grade sealing strip and the floor unit, reducing the risk of liquid seepage. The aforementioned waterproof sealing ring can include an inner layer and an outer layer. The inner layer can be made of highly elastic fluororubber, such as tetrafluoroethylene propylene rubber, which has excellent elasticity and chemical resistance, enabling a tight fit to the control circuit interface. The outer layer can be a wear-resistant modified fluororubber, which can be glued to the outer surface of the inner layer to improve the wear resistance of the waterproof sealing ring and extend its service life. For example, the wear-resistant modified fluororubber can be a blend of fluororubber and polytetrafluoroethylene, which not only has chemical corrosion resistance but also improved wear resistance. The inner and outer layers can be bonded with hot melt adhesive, making them less prone to damage due to friction during long-term use and reducing the risk of leakage. Each of the aforementioned finishing layers 1 can have a downward slope towards a predetermined position, allowing liquid to flow naturally to lower areas and reducing liquid accumulation at the joints. The predetermined position can be located at a corner. The predetermined position can be provided with a liquid collection tank, which can be a funnel-shaped groove with its opening edge smoothly transitioning to the surface of the finishing layer 1. The tank wall can be a smooth curved surface to facilitate smooth liquid flow.The bottom of the aforementioned liquid collection tank can be provided with a drain hole, which can be connected to a pre-laid drainage pipe under the ground. This allows the liquid to be quickly discharged into the drainage pipe through the drain hole, reducing the long-term residence and accumulation of liquid in the finishing layer 1, reducing the risk of liquid erosion and penetration into the floor unit. At the same time, it also helps to keep the surface of the finishing layer 1 dry and reduce the occurrence of safety hazards such as slipping.

[0042] The above-described technical solution, as an inventive point of this disclosure, solves the technical problem of "in the equipment rinsing area of ​​a rehabilitation center's hydrotherapy room, water with a certain pressure and added disinfectant is needed to rinse wheelchairs, stretchers, and other equipment, causing liquid accumulation and increasing the risk of liquid seeping into the gaps between floor units. Simultaneously, the sealing strips installed at the joints between the floor units are easily worn, deformed, or even detached due to frequent pressure from wheelchairs, stretchers, and other equipment, thus affecting the sealing effect, leading to liquid seepage and increasing the risk of bacterial growth." Factors leading to increased bacterial growth often include: in the equipment rinsing area of ​​a rehabilitation center's hydrotherapy room, water with a certain pressure and added disinfectant is needed to rinse wheelchairs, stretchers, and other equipment, causing liquid accumulation and increasing the risk of liquid seeping into the gaps between floor units. Simultaneously, the sealing strips installed at the joints between the floor units are easily worn, deformed, or even detached due to frequent pressure from wheelchairs, stretchers, and other equipment, thus affecting the sealing effect, leading to liquid seepage and increasing the risk of bacterial growth. Solving these factors can reduce bacterial growth. To achieve this effect, the integrated protective fall detection floor system for medical monitoring environments disclosed herein uses medical-grade sealing strips embedded with reinforced fibers to maintain good sealing performance even under frequent pressure from equipment such as wheelchairs and stretchers, preventing liquid from seeping through the seams. A sloping finish layer allows liquid to drain quickly from the floor unit surface, reducing accumulation and lowering the risk of seepage. By employing pH-responsive slow-release antibacterial microcapsules and a double-layered waterproof sealing ring, even if water seeps into the floor units, bacterial growth is inhibited and the control circuit interfaces remain waterproof, reducing bacterial growth and safety hazards, and improving the overall durability and safety of the floor system.

[0043] In addressing the aforementioned technical problems through the adoption of technical solutions, and considering the application scenario of this technical solution—hospital wards in northern regions during winter—the following additional technical issues arise: In these hospital wards during winter, despite indoor heating, the floor's high thermal inertia and significantly lower surface temperature compared to room temperature, coupled with slow warming, can lead to decreased sensitivity of pressure sensors, affecting the accuracy of fall detection. Furthermore, when elderly individuals get up at night, falls can cause vasoconstriction and muscle stiffness upon contact with the cold floor, and the cold ground can accelerate hypothermia, often posing significant safety risks. To address the specific requirements of this application scenario—increasing floor surface temperature and improving fall detection accuracy—we have decided to adopt the following solution: Optionally, the aforementioned integrated protective fall detection floor system for medical monitoring environments may further include underfloor heating pipes. These underfloor heating pipes can be plastic pipes, such as polyethylene or cross-linked polyethylene pipes, possessing good heat resistance, corrosion resistance, and flexibility to meet the long-term use requirements of underfloor heating pipes. An insulation board can be laid between the flexible balancing layer 2 and the supporting plane. This insulation board can be polystyrene foam board or extruded polystyrene foam board, possessing excellent thermal insulation performance, effectively reducing heat loss and increasing the floor surface temperature. The flexible balancing layer 2 may also have pipe grooves, which can be U-shaped grooves that allow the underfloor heating pipes to be embedded within them. The depth of the pipe grooves can be approximately equal to the diameter of the underfloor heating pipes. Both the pipe grooves and the placement grooves 6 can be located on the upper surface of the flexible balancing layer 2, so that the underfloor heating pipes, after being embedded in the pipe grooves, are flush with the upper surface of the flexible balancing layer 2. The aforementioned underfloor heating pipes can be laid in a serpentine pattern within the pipe grooves of multiple flexible balancing layers 2, ensuring even heat distribution and reducing the probability of localized overheating or undercooling. These underfloor heating pipes can be positioned adjacent to the aforementioned pressure sensor array, increasing the array's temperature and effectively preventing sensitivity reduction due to low temperatures in winter, thus improving fall detection accuracy. The ends of the underfloor heating pipes can be connected to a heat source, including but not limited to centralized heating systems, air-source heat pumps, and ground-source heat pumps, providing a stable and continuous heat supply. The surface of the flexible balancing layer 2 can be covered with a reflective film, made of aluminum foil, which has high reflectivity. This reflects the heat emitted by the underfloor heating pipes, reducing downward heat loss, improving heat utilization, and allowing more heat to be transferred upwards to the finishing layer 1. This effectively increases the surface temperature of the finishing layer 1, providing a warmer and more comfortable environment for people in the ward. The aforementioned reflective film can be adhered to the upper surface of the aforementioned flexible balancing layer 2 via a pressure-sensitive adhesive layer, ensuring a tight fit between the reflective film and the flexible balancing layer 2. The pressure sensing layer and the underfloor heating pipes can both be located above the reflective film. The reflective film can reflect the heat emitted by the underfloor heating pipes upwards, reducing heat loss downwards. A surface functional layer can be laid on the upper surface of the aforementioned decorative layer 1. This surface functional layer can be medical-grade PVC flooring, which not only has excellent anti-slip properties, effectively reducing the risk of slipping when walking or falling, but also possesses soft and elastic characteristics. When someone accidentally falls, it can provide a certain cushioning effect, further reducing the injury caused by the fall. Simultaneously, the underfloor heating pipes can maintain a suitable temperature for the surface functional layer. Even in winter, elderly people will not feel cold when they fall, avoiding problems such as vasoconstriction and muscle stiffness caused by contact with a cold floor, thus reducing the risk of hypothermia in the elderly.The upper surface of the aforementioned surface functional layer may be provided with anti-slip texture. The anti-slip texture may be fine ripples, which can increase friction, prevent medical staff or patients from slipping when walking, and improve safety performance.

[0044] The above-described technical solution, as an inventive point of this disclosure, solves the technical problem of "in hospital wards in northern regions during winter, although there is indoor heating, the floor has high thermal inertia, its surface temperature is still significantly lower than the room temperature and heats up slowly. The low temperature easily leads to a decrease in the sensitivity of pressure sensors, affecting the accuracy of fall detection. Furthermore, if an elderly person falls while getting up at night, contact with the cold floor can easily cause vasoconstriction and muscle stiffness. The cold floor also accelerates hypothermia in the elderly, often resulting in a high safety risk." The factors leading to this high safety risk are often as follows: in hospital wards in northern regions during winter, although there is indoor heating, the floor has high thermal inertia, its surface temperature is still significantly lower than the room temperature and heats up slowly. The low temperature easily leads to a decrease in the sensitivity of pressure sensors, affecting the accuracy of fall detection. Furthermore, if an elderly person falls while getting up at night, contact with the cold floor can easily cause vasoconstriction and muscle stiffness. The cold floor also accelerates hypothermia in the elderly, often resulting in a high safety risk. Solving these factors can reduce the safety risk. To achieve this effect, the integrated protective fall detection floor system for medical monitoring environments disclosed herein incorporates pipe grooves in a flexible balancing layer, within which underfloor heating pipes are laid to heat the floor system. This effectively increases the surface temperature of the floor, reducing the risk of hypothermia after a fall in the elderly. Simultaneously, the underfloor heating pipes are positioned adjacent to the pressure sensor array, heating the array and effectively preventing sensitivity loss due to low temperatures in winter, thus improving the accuracy of fall detection. Furthermore, the medical-grade PVC flooring laid on the surface layer not only has excellent anti-slip properties but also possesses softness and elasticity, acting as a cushion when someone falls, reducing the impact of the fall. The finely textured anti-slip surface of the medical-grade PVC flooring further increases friction, preventing slips by medical staff or patients and effectively reducing safety risks.

[0045] The above embodiments of this disclosure have the following beneficial effects: the integrated protective fall detection floor system for medical monitoring environments provided by some embodiments of this disclosure can improve the reliability of the system. Specifically, the reason for the low reliability of the system is that video surveillance has the risk of blind spots, the edges of the pressure sensing pad that are prone to displacement not only bring new tripping risks, but also cannot withstand the repeated crushing of high-frequency disinfection and equipment such as work beds and wheelchairs. At the same time, the pressure sensing pad is prone to absorbing water, which can easily lead to the growth of bacteria inside, often resulting in technical problems of low system reliability. Based on this, some embodiments of this disclosure provide an integrated protective fall detection floor system for medical monitoring environments. The system includes: an adjustable support unit, a floor unit, and a control device; the adjustable support unit includes a support plate and adjustable support legs, and multiple adjustable support units are laid on the ground in an array to form a support plane. The support plate and the ground are connected by the adjustable support legs to form an adjustable layer; the floor unit includes a flexible balance layer, a pressure sensing layer, and a finishing layer. The flexible balance layer is provided with a placement groove, the pressure sensing layer is placed in the placement groove, and the finishing layer is laid on top. Above the flexible balancing layer; the pressure sensing layer includes a pressure sensor array and a data acquisition unit. The pressure sensor array is in contact with the bottom surface of the finishing layer. Multiple floor units are laid in an array on the supporting plane. The pressure sensor array is configured to detect pressure data and is communicatively connected to the data acquisition unit. The data acquisition unit is configured to transmit the pressure data to the control device. The control device is communicatively connected to the data acquisition units of each floor unit via control lines, wherein the control lines are laid in the elevated layer. The elevated adjustment unit provides a concealed and protected path for the control lines. By capturing pressure changes through the pressure sensing layer in the floor units, real-time monitoring of patient falls is achieved. The flexible balancing layer can reduce pain caused by falls. At the same time, the communication connection between the control device and the data acquisition units of each floor unit ensures timely data transmission and processing, further improving the system's response speed and reliability.
