Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0051] In the prior art, CN112294023A discloses an anti-pressure ulcer mattress. This mattress is woven to form multiple support points for supporting the human body to distribute body pressure. However, in the prior art, the support pad area still has continuous pressure from the mattress on the corresponding part of the human body, making it difficult to completely solve the problem of pressure ulcers.

[0052] To address the aforementioned problems in the prior art, the present invention provides a waterbed positioning pad, such as... Figure 1 and Figure 2 As shown, the waterbed positioning pad includes: a pad body 100, in which a plurality of water bladders 110 are arranged; a monitoring component 200, located on the contact side of the pad body 100, including a plurality of flexible thin-film pressure sensors 210 corresponding to the plurality of water bladders 110; an adjustment component 300, located on the control side of the pad body 100, including a plurality of adjustment valves corresponding to the positions between adjacent water bladders 110, the adjustment valves being connected to adjacent water bladders 110 respectively; and a heating component 400, which is positioned corresponding to the plurality of water bladders 110 and is arranged to avoid electronic water valves; the monitoring component 200, the adjustment component 300, and the heating component 400 are electrically connected.

[0053] This invention provides a plurality of water sacs 110 and an adjustment component 300 for adjusting the amount of liquid in the water sacs 110 on the mattress body 100. The contact pressure of the patient is obtained by a flexible thin-film pressure sensor 210 located on the contact side of the mattress body 100, and the adjustment component 300 is used to adjust the amount of liquid in the corresponding water sacs 110 to achieve the effect of dynamically adjusting the pressure points of the patient. The temperature of the water sacs 110 can be controlled by a heating component 400 to improve comfort. This invention can effectively relieve the continuous pressure of the mattress on the patient's contact points and prevent pressure sores from occurring.

[0054] In this embodiment, as Figure 1 and Figure 2As shown, the main body of the waterbed positioning pad of the present invention consists of a pad body 100, a monitoring component 200, an adjustment component 300, and a heating component 400. The pad body 100 is used to support the patient's body. In this embodiment, the pad body 100 is made of an elastic material, such as compressed sponge or rubber. Several water bladders 110 are arranged inside the pad body 100. The water bladders 110 can be made of materials such as PVC or special non-woven fabric, and should have heat resistance, corrosion resistance, and insulation properties. The water bladders 110 are filled with water or other heat-conducting media. In actual use, the patient's body mainly contacts the several water bladders 110. The liquid pressure inside the water bladders 110 forms support for the patient's body, thereby effectively dispersing pressure and improving comfort. Since there are multiple water bladders 110, unlike traditional waterbeds, the structure of multiple water bladders 110 will not cause the patient to shake, ensuring the accuracy of medical staff's nursing operations on the patient.

[0055] In this embodiment, for ease of description, the side of the pad 100 that contacts the patient's body is named the contact side, and the other side of the pad 100 is named the control side. Those skilled in the art will understand that the above naming is only for the convenience of distinguishing the two sides of the pad 100 and does not represent the actual structure.

[0056] The monitoring component 200 is disposed on the contact side of the pad 100. Specifically, the monitoring component 200 includes a plurality of flexible thin-film pressure sensors 210 disposed corresponding to a plurality of water bladders 110. The flexible thin-film pressure sensor 210 is a miniature pressure sensing element made of flexible material. It uses the working principle of resistance, capacitance, piezoelectricity or capacitive-resistive coupling to detect pressure or contact changes. The thickness of the flexible thin-film pressure sensor 210 in the prior art is usually between tens of micrometers and a few millimeters. It can be bent, folded and stretched to sense small pressure changes and has the characteristics of rapid response, such as cellulose-based piezoresistive flexible thin-film pressure sensing materials. In this embodiment, the flexible thin-film pressure sensor 210 is disposed on one side of the water bag 110 corresponding to the contact side. In actual use, it comes into direct or indirect contact with the patient (such as when a window sleeve is set on the outside of the pad 100). During use, the flexible thin-film pressure sensor 210 in the monitoring component 200 can sense the contact pressure between the patient's body and the water bag 110 in real time and transmit it to other functional components that are electrically connected to the monitoring component 200, so as to realize the function of targeted adjustment of the state of the pad 100.

[0057] The adjustment component 300 is specifically used to adjust the liquid volume inside several water sacs 110 within the pad 100, specifically, such as... Figure 2As shown, the adjustment component 300 is located on the control side of the pad 100. The adjustment component 300 includes several adjustment valves, which are fixedly positioned between adjacent water bladders 110 and connected to two adjacent water bladders 110 respectively. This allows the liquid in one water bladder 110 to be transferred to another. Specifically, the adjustment valves are electronic water valves, which are devices that use electronic technology to control water flow. Driven by an electric motor, in this embodiment, when the monitoring component 200 detects that the pressure data transmitted by the flexible thin-film pressure sensor 210 on a certain water bladder 110 exceeds a preset threshold, the processor 500 controls the corresponding adjustment valve to open, transferring some of the liquid in that water bladder 110 to an adjacent water bladder 110, thereby reducing the pressure at that location. The waterbed positioning pad of this invention can achieve real-time monitoring and dynamic adjustment of pressure on various parts of the patient's body, effectively avoiding pressure sores caused by prolonged continuous pressure.

[0058] The heating element 400 is used to heat the water bag 110 to maintain the liquid inside the water bag 110 within a suitable temperature range, improve the patient's comfort, and keep the patient's limbs warm, thereby promoting blood circulation and preventing pressure sores.

[0059] In the above embodiment, the monitoring component 200, the adjustment component 300, and the heating component 400 are connected by electrical signals. By monitoring the pressure points where the patient contacts the pad 100 through several flexible thin-film pressure sensors 210 in the monitoring component, the adjustment component 300 can be controlled to adjust the amount of liquid in different water bags 110, thereby achieving the effect of adjusting the pressure contact points of the patient. At the same time, the heating component 400 can also be controlled to adjust the heating points according to the changes in the water bags 110, thereby achieving targeted adjustment of the temperature of the contact points of the patient. The heating temperature of the heating component 400 can be intelligently adjusted according to a preset suitable temperature range to ensure that the liquid temperature in the water bags 110 is always maintained at the optimal state, matching the dynamic changes of several water bags 110.

[0060] Based on the above embodiments, in one specific embodiment of the present invention, the water bladder 110 is preferably convex on the side facing the contact area, and the flexible thin-film pressure sensor 210 is fitted onto the outer surface of the water bladder 110. This design ensures a close fit between the sensor and the patient's contact area, improving the accuracy and sensitivity of pressure monitoring, while also preventing the flexible thin-film pressure sensor 210 from causing discomfort to the patient. The flexible thin-film pressure sensor 210 is positioned along the length of the water bladder 110, enabling comprehensive monitoring of different parts of the patient's body, ensuring no omissions. When the patient lies on the waterbed positioning pad, the flexible thin-film pressure sensor 210 can sense and transmit pressure data in real time, providing crucial information for subsequent dynamic adjustments.

[0061] In another possible embodiment of the invention, such as Figure 2 and Figure 3 As shown, the aforementioned adjustment assembly 300 includes a plurality of first electronic water valves 310 and a plurality of second electronic water valves 320. The plurality of first electronic water valves 310 are fixedly disposed on the control side of the pad 100, corresponding to one end of the water bladder 110, and are oriented in the same direction to push the liquid in adjacent water bladders 110 in one direction. The plurality of second electronic water valves 320 are fixedly disposed on the control side of the pad 100, corresponding to the other end of the water bladder 110, and are oriented in the same direction. Similar to, but in the opposite direction to, the first electronic water valve 310 is used to push the liquid in the adjacent water sac 110 in another direction. This structural arrangement allows for more flexible adjustment of the liquid within the water sac 110, enabling liquid transfer between adjacent water sacs 110 and ensuring effective pressure regulation of various parts of the patient's body. The arrangement of the first electronic water valve 310 and the second electronic water valve 320 allows for more precise control of the amount and direction of liquid transfer, thereby achieving more accurate pressure regulation of various parts of the patient's body. In actual use, the first electronic water valve 310 and the second electronic water valve 320 are intelligently controlled to open and close based on the pressure data monitored by the monitoring component 200, thereby achieving automated pressure regulation.

[0062] In another possible embodiment of the invention, such as Figure 2 As shown, the heating assembly 400 specifically includes a controller 410 and several heating elements 420 connected to the controller 410 circuitically. The heating elements 420 correspond in position to several water bladders 110, and their shapes are adapted to the shapes of the water bladders 110, arranged along the length of the water bladders 110. Since the amount of liquid in different water bladders 110 varies after adjustment, the controller 410 independently controls the heating temperature of each heating element 420 through the monitoring assembly 200 and the adjustment assembly 300, achieving targeted heating of different water bladders 110 to maintain the liquid within a suitable temperature range and improve patient comfort. The heating elements 420 are preferably made of heating materials with high heating efficiency and good safety performance, such as carbon fiber heating materials or heating wires, to ensure heating effect and safety of use. In actual use, the controller 410 intelligently adjusts the heating temperature of the heating element 420 according to the preset suitable temperature range, ensuring that the liquid temperature in the water bag 110 is always maintained at the optimal state, matching the dynamic changes of several water bags 110, thereby improving the patient's comfort and promoting blood circulation.

[0063] In another possible embodiment of the invention, such as Figure 1 and Figure 2As shown, the aforementioned pad 100 also includes a limiting member 120 circumferentially disposed on the outside of a plurality of water bladders 110. The limiting member 120 is an elastic limiting member 120, which can be made of materials such as compressed sponge or rubber. In this embodiment, the limiting member 120 constrains the position of the plurality of water bladders 110, thereby preventing deformation in the horizontal direction due to changes in the volume of the liquid inside the water bladders 110. In actual manufacturing, adjacent water bladders 110 are fixedly connected to form mutual constraints. The water bladders 110 are fixedly connected to the limiting members 120 at corresponding positions to form further positional constraints. In addition, the limiting member 120 is not limited to being disposed on the periphery. An integral limiting member 120 can also be disposed between adjacent water bladders 110, thereby constraining the shape of the water bladders 110.

[0064] Furthermore, in this embodiment, such as Figure 1 As shown, a processor 500 is also installed on the aforementioned limiting component 120. The processor 500 is signal-connected to the aforementioned monitoring component 200, adjustment component 300, and heating component 400. Through unified coordination by the processor 500, comprehensive monitoring and intelligent adjustment of the pressure, temperature, and fluid volume at the contact points between the patient's body and the waterbed positioning pad are achieved. As the core control unit of the entire system, the processor 500 can receive real-time pressure data from the monitoring component 200, intelligently analyze the pressure distribution of various parts of the patient's body according to preset programs and logical judgments, and issue control commands to the adjustment component 300 and the heating component 400 accordingly. The adjustment component 300, according to the commands of the processor 500, precisely adjusts the fluid volume in each water bladder 110 to achieve dynamic balance and dispersion of pressure, effectively avoiding pressure sores caused by prolonged local pressure. At the same time, the heating component 400, according to the commands of the processor 500, independently controls the heating temperature of each heating element 420 to ensure that the fluid in the water bladder 110 is always within a suitable temperature range, improving patient comfort and promoting blood circulation. Through such comprehensive monitoring and intelligent adjustment, the waterbed positioning pad of the present invention can provide patients with a safer, more comfortable and effective nursing experience.

[0065] Furthermore, communication components, such as Bluetooth and data transmission modules, can be installed on the processor 500 to enable remote monitoring and data transmission. The remote monitoring terminal, such as a smart terminal used by medical staff, can obtain real-time information about the working status of the waterbed positioning pad through the communication components, including pressure data of various parts of the patient's body, the amount of liquid in the water bladder 110, and the heating temperature, thereby enabling remote care and monitoring of the patient. This design not only improves nursing efficiency but also enhances the precision and safety of nursing care.

[0066] Based on the above embodiments, the actual usage process of the waterbed positioning pad of the present invention is as follows:

[0067] First, medical staff place the patient on the waterbed positioning pad, with the patient's body in contact with the water bladder 110. The flexible thin-film pressure sensor 210 begins to sense and transmit the contact pressure data between the patient's body and the water bladder 110 to the processor 500 in real time. After receiving the pressure data, the processor 500 intelligently analyzes the pressure distribution of different parts of the patient's body according to preset programs and logic. If the pressure at a certain location exceeds a certain duration or threshold, the processor 500 immediately sends a control command to the corresponding regulating component 300. The first electronic water valve 310 and the second electronic water valve 320 in the regulating component 300 precisely open and close according to the processor 500's command, realizing the mutual transfer of liquid between adjacent water bladders 110, thereby reducing the pressure at that location and achieving the effect of dynamic balance and pressure dispersion.

[0068] Simultaneously, the processor 500 sends control commands to the heating component 400 based on the pressure distribution. The controller 410 in the heating component 400 independently controls the heating temperature of each heating element 420 according to the commands, ensuring that the liquid in the water bladder 110 is always within a suitable temperature range to improve patient comfort and promote blood circulation. Through such comprehensive monitoring and intelligent adjustment, the waterbed positioning pad can respond to changes in patient body pressure in real time, effectively avoiding pressure sores caused by prolonged local pressure.

[0069] Furthermore, medical staff can obtain real-time monitoring data on the waterbed positioning pad through a remote monitoring terminal, including pressure data of various parts of the patient's body, the amount of liquid in the water bladder 110, and the heating temperature, thereby enabling remote care and monitoring of the patient. This design not only improves nursing efficiency but also enhances the precision and safety of care, providing patients with a safer, more comfortable, and effective nursing experience.

[0070] Based on the above embodiments, the present invention also provides a method for controlling pressure sores using a waterbed positioning pad, such as... Figure 4 As shown, the method for preventing pressure sores using the waterbed positioning pad includes:

[0071] S10. Group the water bladders on the pad body;

[0072] S20. Obtain the pressure peak data of several of the flexible thin-film pressure sensors within the cycle time limit;

[0073] S30. Calculate the average pressure of different groups based on several of the pressure peak data, and compare the average pressure of different groups to generate pressure comparison data;

[0074] S40. Adjust the volume of liquid in several water bladders according to the pressure comparison data, and adjust the heating power of the heating component corresponding to the positions of several water bladders.

[0075] Specifically, in step S10, several water sacs on the pad are grouped so that the liquid inside the water sacs can be uniformly regulated on a group basis. Compared with independent regulation of each water sac, this control method can relieve the pressure on the patient's skin, significantly reduce the processing pressure, reduce manufacturing costs, and improve response speed.

[0076] In step S20, pressure peak data from several flexible thin-film pressure sensors are acquired within a certain cycle time limit. The cycle time limit can be set according to actual conditions, for example, it can be set to one minute, five minutes, or longer. The flexible thin-film pressure sensors can sense and transmit the contact pressure data between the patient's body and the water bag in real time. The processor can record and store the pressure peak data within each cycle time limit for subsequent analysis and comparison.

[0077] In step S30, the average pressure of different groups is calculated based on several pressure peak data points, and the average pressure of different groups is compared to generate pressure comparison data. The processor can average the pressure peak data of the water bladders within each group to obtain the average pressure of each group. Then, the processor can compare the average pressure of different groups to determine which groups' corresponding water bladders experience higher or lower pressures, generating corresponding pressure comparison data.

[0078] In step S40, the volume of liquid in several water sacs is adjusted according to pressure comparison data, and the heating power of the heating component corresponding to the positions of several water sacs is adjusted. The processor can send control commands to the adjustment component based on the pressure comparison data to adjust the volume of liquid in the corresponding water sacs, thereby dynamically adjusting the pressure points on the patient. Simultaneously, the processor can also send control commands to the heating component based on the pressure comparison data to adjust the heating power of the corresponding water sac positions, ensuring that the liquid in the water sacs remains within a suitable temperature range, improving patient comfort and promoting blood circulation. Through this pressure ulcer prevention method, the waterbed positioning pad of the present invention can achieve real-time monitoring and dynamic adjustment of pressure on various parts of the patient's body, effectively avoiding pressure ulcers caused by prolonged continuous pressure.

[0079] Furthermore, the grouping of the plurality of water sacs on the pad body includes:

[0080] S11. The water bladders are sequentially numbered;

[0081] S12. Set the water bladders with odd numbers as one group and the water bladders with even numbers as another group.

[0082] In one specific embodiment of the present invention, such as Figure 1As shown, the water bladders on the pad are arranged in a row. In this embodiment, the water bladders can be specifically configured into two groups, with the two groups spaced apart. That is, water bladders with odd numbers form one group, and water bladders with even numbers form another group. When the volume of liquid in the water bladders is adjusted according to the pressure, the odd-numbered group and the even-numbered group of water bladders can alternately support the patient's body. This method can prevent a certain part of the patient's body from continuously contacting the pad, and it will not affect the support of the pad. In addition, it can achieve a more uniform distribution of pressure on various parts of the patient's body. In actual operation, when the processor analyzes that the pressure on a certain group of water bladders is high, it will control the liquid in that group of water bladders to transfer to another group of water bladders through the adjustment component, thereby achieving pressure dispersion and balance. Since the water bladders in different groups are adjacent, the response speed of liquid transfer can be improved, achieving efficient adjustment and saving energy.

[0083] In another possible embodiment of the present invention, obtaining the pressure peak data of a plurality of the flexible thin-film pressure sensors within a cycle time period includes:

[0084] S21. Set a predetermined time, wherein the predetermined time is a unit duration in the cycle time limit;

[0085] S22. Acquire multiple pressure data from a plurality of the flexible thin-film pressure sensors within the predetermined time period;

[0086] S23. Compare multiple pressure data points and define the maximum value among the pressure data points as the pressure peak data.

[0087] In this embodiment, a predetermined time is set to more accurately monitor and analyze pressure data and ensure alternating support for different groups of water bladders. The predetermined time can be set according to actual conditions, for example, in a five-minute or ten-minute format. This predetermined time is a unit duration within the cycle time limit, meaning that adjustments are made every predetermined time interval. Within the predetermined time, the flexible thin-film pressure sensor senses and transmits multiple pressure data points to the processor in real time. The processor can record and store these pressure data points for subsequent analysis and comparison. Comparing multiple pressure data points is to find the maximum pressure value within the predetermined time, i.e., the pressure peak data. The pressure peak data reflects the maximum contact pressure between the patient's body and the water bladder within the predetermined time, and is an important indicator for assessing the patient's pressure condition. The processor can store and accumulate the pressure peak data within each predetermined time interval for subsequent comparison and analysis of pressure peak data within different cycle time limits. Through this setting, the waterbed positioning pad of the present invention can more accurately monitor and analyze pressure changes in various parts of the patient's body, providing more accurate data support for subsequent pressure and heating adjustments.

[0088] Furthermore, the pressure averages of different groups are compared to generate pressure comparison data, including:

[0089] S31. Label the average pressure values ​​of different groups, wherein the labels contain group information;

[0090] S32. Compare the average pressure values ​​of different groups, and generate pressure comparison data based on the comparison results. The pressure comparison data includes the group information, pressure ranking, and the difference between the average pressure values ​​of different groups.

[0091] In step S31, labeling the average pressure values ​​of different groups facilitates subsequent comparison and analysis. The labels can contain grouping information; for example, water bladder groups with odd-numbered labels can be labeled Group A, and water bladder groups with even-numbered labels can be labeled Group B. This way, when the processor performs comparisons, it can clearly identify the group corresponding to each average pressure value, avoiding confusion.

[0092] In step S32, the processor compares the average pressure values ​​of different groups and generates pressure comparison data based on the comparison results. The pressure comparison data may include group information, pressure ranking, and the difference between the average pressure values ​​of different groups. Pressure ranking refers to sorting different groups according to the magnitude of their average pressure values; for example, the group with the highest average pressure value can be ranked first, and the group with the lowest average pressure value last. The difference between the average pressure values ​​of different groups refers to the difference in average pressure values ​​between adjacent groups, reflecting the differences in pressure distribution at different body parts. Through such comparison and analysis, the processor can more accurately understand the pressure distribution at different parts of the patient's body, providing more precise guidance for subsequent pressure and heating adjustments.

[0093] Furthermore, adjusting the volume of liquid within the plurality of water bladders based on the pressure comparison data, and adjusting the heating power of the heating component corresponding to the positions of the plurality of water bladders, includes:

[0094] S41. Obtain the pressure comparison data;

[0095] S42. Based on the grouping information and pressure sorting in the pressure comparison data, the liquid in the water bladder of the group with the highest average pressure is transported to the adjacent water bladders of other groups; the amount of liquid transported is positively correlated with the difference in the average pressure of the different groups;

[0096] S43. Adjust the heating power of the heating component corresponding to the positions of the several water bags according to the amount of liquid delivered.

[0097] In step S41, the processor first acquires the pressure comparison data generated in the previous steps, which forms the basis for subsequent adjustments. The pressure comparison data includes grouping information, pressure ranking, and the difference in average pressure values ​​between different groups. This data comprehensively reflects the pressure distribution in various parts of the patient's body.

[0098] In step S42, the processor determines the group with the highest average pressure, i.e., the area under the most pressure, based on the grouping information and pressure ranking in the pressure comparison data. To alleviate the pressure at this area, the processor controls the regulating component to transfer liquid from the water bladders in this group to adjacent water bladders in other groups. The amount of liquid transferred is determined based on the difference in average pressure between different groups. The larger the difference, the greater the pressure difference between adjacent groups, and therefore the more liquid needs to be transferred to achieve pressure balance and dispersion. Through this adjustment, the waterbed positioning pad of the present invention can respond to pressure changes in the patient's body in real time, effectively avoiding prolonged local pressure.

[0099] In step S43, as the liquid transfers between the water bladders, the volume of liquid within each bladder changes, which may affect the temperature distribution within the bladder. Therefore, after adjusting the liquid volume, the processor also needs to adjust the heating power of the heating components corresponding to each water bladder position based on the liquid delivery rate. By independently controlling the heating temperature of each heating element, it ensures that the liquid within the water bladder remains within a suitable temperature range, thereby improving patient comfort and promoting blood circulation. This comprehensive monitoring and intelligent adjustment enable the waterbed positioning pad of the present invention to provide patients with a safer, more comfortable, and more effective nursing experience.

[0100] In summary, this invention provides a waterbed positioning pad and a method for controlling pressure ulcers using the waterbed positioning pad. The waterbed positioning pad includes: a pad body with a plurality of water bladders arranged within it; a monitoring component located on the contact side of the pad body, including a plurality of flexible thin-film pressure sensors corresponding to the water bladders; an adjustment component located on the control side of the pad body, including a plurality of adjustment valves corresponding to the positions between adjacent water bladders, the adjustment valves being connected to adjacent water bladders; and a heating component located corresponding to the positions of the water bladders and avoiding electronic water valves. The monitoring component, adjustment component, and heating component are electrically connected. This invention provides a plurality of water bladders on the pad body and an adjustment component for adjusting the amount of liquid in the water bladders. The flexible thin-film pressure sensors located on the contact side of the pad body acquire the patient's contact pressure status, thereby controlling the adjustment component to adjust the amount of liquid in the corresponding water bladders to achieve dynamic adjustment of the patient's pressure points. The heating component controls the water bladder temperature to improve comfort. This invention effectively alleviates the continuous pressure of the mattress on the patient's contact points and prevents pressure ulcers.
