Description

Technical Field

[0001] This specification relates to the field of healthcare, and more specifically, the present application relates to an AI voice anti-bedsore pressure relief air cushion, control method, device and air mattress. Background Art

[0002] Anti-bedsore pressure-reducing air mattresses are widely used in medical care settings, primarily to reduce localized pressure on bedridden patients and prevent the development of bedsores. Currently, commonly used air mattresses in clinical practice typically consist of an integrated air cushion and an external electric air pump. The working principle of this device is that the air pump continuously or intermittently injects air into the cushion to create a certain support force, thereby dissipating pressure on the patient's body surface.

[0003] However, the existing technology still has the following prominent problems and limitations:

[0004] 1. Single operation mode, requiring manual intervention: Currently, most air mattresses rely on manual buttons or knobs for operation. Patients themselves find it difficult to actively adjust the air mattress state, and nursing staff need to frequently participate in the adjustment, increasing the workload;

[0005] 2. The inflation area is highly integrated and lacks local control capabilities: Most traditional air cushions have an overall cavity structure or a left-right partitioned structure. They lack independent control of specific pressure areas (such as the buttocks) and cannot be flexibly deflated according to care needs, especially in scenarios such as going to the toilet and turning over.

[0006] 3. Strong dependence on continuous power supply and limited use environment: Most traditional air pumps need to be continuously connected to the power supply and cannot work after power failure, which limits the use of air mattresses in mobile scenarios;

[0007] 4. The surface material has low friction, and the sheets are prone to slipping and wrinkling: Some air cushions are made of ordinary smooth fabrics, which have poor fit with the sheets and are prone to wrinkling or slipping due to changes in the patient's body position, increasing the risk of bedsores.

[0008] There is an urgent need in the art for an intelligent anti-bedsore mattress to at least solve some of the above problems. Summary of the Invention

It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein.

For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or that are inherent to these processes, methods, products or devices. The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments.

[0052] See also Figure 1 , an AI voice-controlled anti-bedsore pressure-reducing air cushion provided in an embodiment of the present application, may specifically include:

[0053] The voice-controlled air pump 101 is used to start or stop the air pump according to the voice command of the target person;

[0054] The air cushion body 102 includes a first cavity 1021, a second cavity 1022, and a third cavity 1023. The first cavity 1021, the second cavity 1022, and the third cavity 1023 are respectively connected to the voice-controlled air pump 101;

[0055] The air outlet 103 includes a first air outlet 1031, a second air outlet 1032 and a third air outlet 1033. The first air outlet 1031 is connected to the first cavity 1021, the second air outlet 1032 is connected to the second cavity 1022, and the third air outlet 1033 is connected to the third cavity 1023. The first air outlet 1031, the second air outlet 1032 and the third air outlet 1033 control the opening and closing states of the corresponding air outlets according to the voice commands.

[0056] For example, this embodiment discloses an AI voice-controlled anti-bedsore pressure-reducing air mattress, which includes three main structural modules: a voice-controlled air pump, an air mattress body, and an air outlet. The various parts are connected and linked through pipelines and control signals to achieve zoned inflation control and intelligent voice interaction functions.

[0057] Specifically, the voice-controlled air pump 101 serves as the control core, housing an AI voice recognition module and a power storage module. It receives and interprets voice commands from a target user, controlling the pump's operating state based on the analysis results to activate inflation or deflation of a designated cavity. The pump supports independent control of multiple air cushion zones, offering automatic inflation, deflation, and pressure balance, enabling intelligent responses without manual intervention.

[0058] The air cushion body 102 is the core pressure-bearing structure used to support the patient's body. Its interior is divided into three parts: a first cavity 1021, a second cavity 1022, and a third cavity 1023, corresponding to the left side, buttocks, and right side of the patient's body, respectively. The first cavity 1021 is set on the left side of the air cushion to support the patient's left half of the body; the second cavity 1022 is set in the middle of the air cushion, corresponding to the patient's buttocks, which is a key protection area for preventing pressure sores; the third cavity 1023 is set on the right side of the air cushion to support the patient's right half of the body. The above three cavities are connected to the voice-controlled air pump 101 through connecting hoses, forming independent, isolated inflation units, allowing the air cushion to accurately and locally adjust the air pressure according to nursing needs.

[0059] The air outlets 103 include a first air outlet 1031, a second air outlet 1032, and a third air outlet 1033, which are connected to the first cavity 1021, the second cavity 1022, and the third cavity 1023, respectively. Each air outlet is equipped with an electrically controllable valve. The opening and closing of the air outlets are controlled by the voice-controlled air pump 101. When the target person issues a voice command such as "Deflate right side" or "Inflate buttocks," the system recognizes the command and automatically controls the corresponding air outlet to open or close, thereby achieving deflation or inflation of the target cavity.

[0060] In practice, when a patient needs to use the toilet, they can issue a "deflate hip" command, causing the system to quickly deflate the second cavity 1022, making room for a bedpan and facilitating nursing care. When a patient needs to roll to the left, they can issue a "deflate right" command, causing the third cavity 1023 to deflate, forming an inclined surface to facilitate smooth position transitions. Similarly, if they need to roll to the right, they can issue a "deflate left" command, causing the first cavity 1021 to deflate, creating a support angle. The system also supports restorative commands such as "inflate left" and "inflate right," allowing the bed surface to return to a horizontal support state.

[0061] Through the above design, the AI ​​voice-controlled anti-bedsore pressure-reducing air mattress provided by the present invention has functional features such as partition control, voice interaction, and autonomous inflation and deflation. It can not only meet the diverse nursing needs of patients, but also significantly reduce the burden on nursing staff and improve the intelligence and humanization level of the equipment.

[0062] This embodiment proposes an AI voice-controlled anti-bedsore pressure-reducing air cushion that integrates AI voice recognition technology with an air pump control system. Patients or caregivers can complete inflation and deflation operations through voice commands without manual intervention, effectively improving the patient's independent operation ability. It is particularly suitable for elderly people with limited mobility or postoperative patients. The air cushion body is divided into a left chamber (first chamber), a buttocks chamber (second chamber), and a right chamber (third chamber), which are independent of each other. This structure supports dynamic adjustment of local air pressure, allowing the target chamber pressure to be individually adjusted in specific scenarios such as toileting, turning over, and lying on the side, making care more precise, positioning more stable, and use safer. Each chamber is equipped with an independent air outlet and an electronically controlled valve, which are linked to the voice-controlled air pump to achieve directional airflow control. The system controls the opening or closing of the target air outlet according to voice commands, achieving rapid response and improving control accuracy. The voice-controlled air pump integrates a battery energy storage module and can operate independently without external power supply after being fully charged, improving the device's adaptability and stability in scenarios such as power outages, mobile wards, and temporary field care. To sum up, this embodiment achieves refined local support through a three-cavity layout in structure, and introduces voice interaction to replace manual operation in control mode, which improves the intelligence level, nursing convenience and safety of use of the pressure-reducing air mattress, and has obvious technological advancement and wide promotion and application value.

[0063] In a feasible embodiment, the second cavity 1022 is located between the first cavity 1021 and the third cavity 10223 , and the first cavity 1021 and the third cavity 1023 are symmetrically arranged with respect to the second cavity 1022 .

[0064] Exemplarily, the second cavity is located between the first and third cavities, forming a three-cavity parallel arrangement. The first cavity is located on the left side of the air cushion, the third cavity is located on the right side of the air cushion, and the second cavity corresponds to the hip area in the middle of the air cushion. The symmetrical arrangement of the first and third cavities with the second cavity as the center not only facilitates dynamic balance of support forces on both sides of the mattress, but also facilitates the system to symmetrically adjust the air pressure on both sides to form a suitable tilt angle during the turning assistance process, thereby enhancing support stability and smooth operation.

[0065] For example, to enhance the system's independent operation capabilities and prevent the mattress's functionality from being affected by unstable external power, one feasible implementation incorporates an integrated energy storage module into the voice-controlled air pump. This module can be pre-charged with an external power source and then continuously powered to the voice recognition unit, electronically controlled valves, and air pump motor. This configuration allows the device to continue operating even during temporary power outages or during mobile scenarios, enhancing the system's flexibility and safety.

[0066] In a feasible embodiment, the voice-controlled air pump includes an electric energy storage module; and / or,

[0067] The surface of the pressure-reducing air cushion comprises flocked antibacterial fabric.

[0068] For example, the pressure-reducing air cushion is covered with flocked antibacterial fabric. The flocking material is skin-friendly and soft, reducing friction and irritation from prolonged contact with the skin. The antibacterial treatment helps prevent the growth of germs and improves overall hygiene. The surface material also has a high coefficient of friction, effectively preventing the sheets from slipping or wrinkling when the patient turns over or sits up, thereby reducing the risk of pressure sores and reducing the workload of nursing and maintenance.

[0069] In summary, the above-mentioned implementation method has made multiple optimizations in terms of structural symmetry, endurance and surface comfort, further enhancing the functionality, practicality and humanized design level, and is particularly suitable for the nursing assistance needs of long-term bedridden patients.

[0070] In a second aspect, the present invention further provides a control method for the AI ​​voice-controlled anti-bedsore pressure-reducing air cushion according to the first aspect of claim 1, comprising:

[0071] S210, obtaining a voice command from the target person;

[0072] S220, identifying the patient's target action corresponding to the voice command;

[0073] S230. Control the start or stop of the voice-controlled air pump according to the patient's target action, and control the opening and closing state of the air outlet, so that each cavity of the air cushion body reaches the target pressure corresponding to the patient's target action.

[0074] For example, in step S210, the system acquires a voice command from the target person. The voice command can be issued by the patient or a caregiver using natural language, such as "deflate left side," "inflate hips," or "stop." This voice command is collected in real time by a voice acquisition device installed inside or outside the air pump and fed into the built-in AI voice recognition module for semantic analysis.

[0075] Next, in step S220, the system performs semantic recognition and motion analysis on the voice commands, extracting the patient's target action corresponding to the command. For example, "Deflate right side" is interpreted as controlling the right cavity (i.e., the third cavity) of the air cushion to deflate; "Inflate hips" corresponds to controlling the middle cavity (i.e., the second cavity) to inflate; and "Stop" is interpreted as terminating the current air pump operation. This recognition process can achieve multi-semantic adaptation based on preset command templates or through a neural network model.

[0076] Finally, in step S230, the system automatically controls the start or stop of the voice-controlled air pump based on the identified patient's target action, and further controls the opening and closing of the corresponding air outlet. Specifically, when the target action is "deflation," the system controls the air pump to stop output and opens the air outlet valve of the corresponding cavity to achieve rapid deflation; when the target action is "inflation," the system controls the air pump to start and close the air outlet of the target cavity, and the pump body injects gas into the cavity to increase the local support strength. Through this control process, the air pressure state of each cavity in the air cushion body can be automatically adjusted to the target pressure level that matches the target action, such as deflation to a soft state or inflation to a support state.

[0077] For example, when the patient needs to go to the toilet, he can issue the "deflate buttocks" command, and the system will automatically control the second cavity to deflate and release the middle space; when the patient is ready to turn over to the left, he can issue the "deflate right side" command, and the third cavity will automatically release pressure to form an appropriate inclination angle to assist in completing the turning action; after the care is completed, the "recovery" command can be used to re-inflate each cavity and restore the standard support form.

[0078] Through the above steps, this method realizes the closed-loop control process of voice recognition, motion analysis and intelligent pressure control of the anti-bedsore air mattress, which significantly improves the intelligence level, autonomous adaptability and patient operation convenience of the mattress system.

[0079] In a feasible embodiment, controlling the start or stop of the voice-controlled air pump and the opening and closing state of the air outlet according to the patient's target action so that each cavity of the air cushion body reaches the target pressure corresponding to the patient's target action includes:

[0080] When the patient's target action is placing the bedpan, controlling the start or stop of the voice-controlled air pump and the opening and closing of the air outlet to make the pressure of the second cavity of the air cushion body less than a first preset threshold, and making the pressures of the first cavity and the second cavity greater than the second preset threshold, wherein the second preset threshold is greater than the first preset threshold, and the pressure difference between the first cavity and the second cavity is less than the first preset threshold;

[0081] and / or;

[0082] When the patient's target movement is a sideways movement, the pressure difference between the first cavity and the second cavity is greater than the third preset threshold, wherein the third preset threshold is smaller than the second preset threshold, and the third preset threshold is greater than the first preset threshold.

[0083] For example, when the identified patient target action is "place the bedpan," the system will control the voice-controlled air pump and air outlet to rapidly reduce the pressure in the second cavity corresponding to the buttocks, thereby forming a concave area for placing the bedpan. At this time, the system controls the pressure of the second cavity to drop below a first preset threshold, for example, to a near-zero pressure state; at the same time, the normal support function of the left first cavity and the right third cavity is maintained, with the pressure above the second preset threshold to ensure sufficient support on both sides of the patient's body and prevent tipping or sliding.

[0084] To ensure stability, the system also controls the pressure difference between the first and third cavities to be less than a first preset threshold, maintaining essentially the same pressure on both sides to avoid discomfort caused by uneven pressure. The first preset threshold can be a softening reference pressure (e.g., 3kPa), and the second preset threshold is a normal support pressure (e.g., 10kPa). The difference between the two is used to calibrate the boundary between deflation and support.

[0085] On the other hand, when the identified patient target action is a "sideways movement" (such as turning over to the left or right), the system will actively create a significant pressure difference between the contralateral cavity of the body and the other cavities. For example, when the patient is about to turn over to the left, the system controls the third cavity (right side) to deflate to below the first preset threshold, while maintaining the normal support pressure of the first cavity and the second cavity (left side and buttocks). At this time, the air cushion in the left area is significantly higher than that on the right side, forming an inclination angle to the left, which helps the patient to turn over smoothly. The pressure difference between the above-mentioned first cavity and the third cavity is greater than the third preset threshold to ensure an effective side tilt support effect.

[0086] In this setting, the third preset threshold is between the first preset threshold and the second preset threshold, and plays a critical role in determining the pressure difference between support and deflation. For example, it can be set to 7kPa to determine whether the cavity has sufficient turning-over guiding force.

[0087] Through the above design, this embodiment not only realizes cavity partitioning in structure, but also closely links voice control with cavity pressure regulation through motion-pressure mapping logic. It has the advantages of intelligent response, precise support, and adaptability to various body position change needs, effectively improving the adaptability and care efficiency of the anti-bedsore mattress.

[0088] In a feasible implementation, it further includes:

[0089] Obtain the target patient's level of care;

[0090] Identify the identity information of the above-mentioned target persons;

[0091] Determine the target person's authority to give instructions based on the aforementioned care level and identity information;

[0092] Determine whether the voice command can execute the corresponding action based on the command authority and the voice command of the target person;

[0093] If the voice command can execute a corresponding action, the voice-controlled air pump is controlled to start or stop, and the opening and closing state of the air outlet is controlled according to the patient's target action, so that each cavity of the air cushion body reaches the target pressure corresponding to the patient's target action; or

[0094] In the case that the above-mentioned voice instruction cannot perform the corresponding action, voice feedback information is generated to prompt the above-mentioned target person that the action corresponding to the above-mentioned voice instruction cannot be performed at present.

[0095] For example, the system first obtains the target patient's nursing level information through the nursing platform or a bound terminal. Nursing levels can be categorized into primary care, secondary care, and intensive care based on medical assessment standards. Each level corresponds to a different operational risk tolerance and functional accessibility. The system also identifies the voice sender's identity, such as the patient, nurse, doctor, or accompanying person.

[0096] After identification is complete, the system dynamically generates a set of voice command permissions for the target person based on the preset permission policy, combined with the nursing level and identity information. For example, a Level 1 patient can only perform basic positioning commands, while complex operations (such as full deflation and full bed tilt) are limited to nursing staff. Nurses, on the other hand, have full control permissions.

[0097] When the system receives a voice command, it first verifies the permissions of the target person, determining whether the action is permitted based on the target person's permissions. For example, if a patient in a general care setting issues the "deflate hip" command, the system verifies whether the person has permission to deflate. If so, the system executes the action as normal.

[0098] Specifically, when the voice command authority verification is passed, the system will control the start or stop of the voice-controlled air pump according to the identified patient target action, and at the same time control the opening and closing state of the corresponding air outlet, so that each cavity in the air cushion body is adjusted to the target pressure level corresponding to the target action, such as hip deflation, side tilt support, etc.

[0099] Conversely, if the system determines that the voice command exceeds the current person's command authority, the corresponding action will not be executed. In this case, the system will generate voice feedback information and prompt the target person through the speaker, such as playing a prompt such as "Current operation is not allowed, please contact nursing staff", to ensure safe operation, clarify boundaries, and avoid accidentally triggering high-risk functions.

[0100] By introducing this permission control mechanism, this embodiment not only improves the intelligence and refinement of the air cushion control system, but also effectively prevents misoperation and unauthorized control. It is particularly suitable for safety management and nursing operation optimization in multi-role sharing scenarios (such as wards, nursing homes, etc.), and has significant clinical application value.

[0101] In a feasible implementation, the above-mentioned determination of the instruction authority of the target person based on the above-mentioned nursing level and the above-mentioned identity information includes:

[0102] Based on the above nursing level information and the above identity information, the permission mapping relationship table is queried to determine whether the above target person has the permission to perform the operation corresponding to the above voice command.

[0103] For example, to achieve differentiated management of voice control permissions for individuals of different identities at different care levels, this application proposes a permission determination mechanism based on a permission mapping table. This mechanism automatically determines whether the current voice sender has permission to perform the operation before the system executes the voice control command, thereby improving the operational safety and management standardization of the air mattress system.

[0104] Specifically, after receiving a voice command from the target person, the system first extracts the target person's nursing level and identity information from pre-stored user data. Nursing level information is typically generated by medical institutions based on the patient's physical condition, such as primary care, secondary care, or intensive care. Identity information can be determined based on voice recognition or device binding information, such as the patient, registered nurse, doctor, or accompanying family member.

[0105] Subsequently, the system uses the above nursing level and identity information as joint query conditions and performs a matching query in the preset permission mapping relationship table. The permission mapping relationship table is a data structure used for permission control. The table presets the operation permission sets corresponding to different nursing levels and identity roles. For example, as shown in Table 1:

[0106] Level of care Identity role Allow command permissions First-level care The patient himself Adjust left and right softness and hardness, and pause inflation First-level care Nurse All local adjustment operations (including deflation of the buttocks) Special care doctor All operations (including quick deflation and overall adjustment)

[0107] Table 1

[0108] When the system finds a permission set corresponding to the current person's identity and nursing level in the table, it can further determine whether they have the permission to perform the action corresponding to the current voice command. For example, if a patient with a lower nursing level attempts to issue the "deflate hip" command, but the table does not specify that permission, the system will refuse to execute the command.

[0109] This judgment process is automatically completed by the system logic module, without the need for human intervention. If the authorization verification is successful, the system will control the voice air pump and air outlet according to the established process to complete the corresponding air pressure adjustment. If the authorization verification fails, the system will generate a voice feedback message to inform the target person that the current operation is not allowed.

[0110] By introducing the above-mentioned permission mapping mechanism based on nursing level and identity role, this embodiment effectively realizes the hierarchical management of operation permissions, which not only guarantees the patient's basic self-adjustment needs, but also controls the authorization scope of high-risk operation permissions, thereby improving the use safety and management efficiency of the smart air mattress in a multi-role sharing environment.

[0111] In a feasible implementation, obtaining the nursing level of the target patient includes:

[0112] Determine the nursing level of the target patient based on the QR code information of the target patient's wristband, wherein the nursing level is dynamically adjusted;

[0113] The above-mentioned identification information of the target persons includes:

[0114] Obtain the target person's wristband QR code information and the standard voice information of the start command for identity binding;

[0115] Before controlling the above-mentioned decompression air cushion, a start-up instruction of the above-mentioned target person is obtained to identify the identity information of the above-mentioned target person.

[0116] For example, before the system executes voice commands, it first needs to obtain the target patient's nursing level information. This process is achieved by reading the QR code information in the electronic bracelet worn by the patient. The system can obtain the unique identification code corresponding to the QR code through the built-in scanning module or by communicating with an external device (such as a mobile terminal). Based on the identification code, the system then queries the patient's current nursing level information from the nursing information system, such as first-level nursing, special nursing, intensive care, etc.

[0117] Nursing level information is dynamically adjusted, meaning it's updated in real time by medical staff in the backend system as the patient's condition changes. Each time the system reads the QR code, it simultaneously queries the latest level, enabling dynamic adaptation of patient care permissions.

[0118] To identify and confirm the identity of the person issuing the voice command, the system also includes a voice binding and verification mechanism. During first use or system initialization, the system establishes a unique identity binding relationship by obtaining the target person's wristband QR code information and the standard activation voice message issued by the target person. This standard voice message can be a phrase with activation characteristics such as "I am XXX" or "Start operating the air cushion."

[0119] Before each voice control command is issued, the system asks the user to speak the activation phrase and then matches it with the QR code information of the wristband currently being worn, thus implementing two-factor identity authentication. The system verifies the operator's identity by comparing voice characteristics and the device's unique identifier, ensuring that the voice command comes from a reliable source and that the authority is reasonable.

[0120] For example, if the system recognizes that the bracelet QR code corresponds to the patient's identity and the voice match is consistent, it will be determined that the voice operation comes from the patient himself; if it is recognized as a nurse or doctor, the corresponding permission set will be further loaded.

[0121] Through this mechanism, the system automatically completes identity recognition and care level confirmation before controlling the air pump and outlet, and uses this as one of the criteria for determining whether to execute the current voice command. Combined with the permission mapping table, the system ultimately decides whether to execute the voice control action or provide voice feedback prompts.

[0122] To sum up, this embodiment not only improves the accuracy and security of identity recognition by introducing a combination of wristband QR code and voice recognition, but also realizes the automatic acquisition and dynamic update of nursing levels, so that the AI ​​voice-controlled decompression air mattress has key capabilities such as intelligent recognition, dynamic authorization, and risk control, which significantly enhances the practicality and clinical adaptability of the system.

[0123] In the third aspect, the present invention also proposes an electronic device 300, comprising a memory 310, a processor 320, and a computer program 311 stored in the memory 310 and executable on the processor. When the processor 320 executes the computer program 311, the steps of the control method described in any one of the second aspects are implemented.
