[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The present invention provides a technical solution: a nursing monitoring device, characterized in that the nursing monitoring device comprises an upper conductive component and a lower conductive component, an insulating component is arranged between the upper conductive component and the lower conductive component, the insulating component is provided with a hollow area, and one end of the upper conductive component and / or the lower conductive component is connected to a controller; when a human body applies pressure to the upper conductive component, the upper conductive component and the lower conductive component are electrically connected through the hollow area in the insulating component, and the controller is used to convert an electrical signal generated by the electrical connection into a pressure warning signal.

[0030] The upper conductive component refers to a part of the internal structure of the pressure sensing pad, which is composed of an upper conductive structure and an upper plastic structure. The main function of this component is to form an electrical connection with the lower conductive component when pressure is applied, thereby completing the circuit, and to disconnect the electrical connection when the pressure is removed or changed.

[0031] The lower conductive component also refers to a part of the internal structure of the pressure sensing pad, which includes a lower conductive structure and a lower plastic structure. This part functions similarly to the upper conductive component, remaining separated when there is no pressure; and when pressure is applied, it contacts the upper conductive component to complete the circuit closure.

[0032] The insulating component is a layer of material located between the upper and lower conductive components. Its main function is to prevent the two layers from directly contacting each other without external pressure. This component is usually a layer of insulating foam with regularly arranged hollow gaps on it.

[0033] Hollow areas refer to pre-set openings or gaps in insulating components. These hollow areas allow the upper and lower conductive components to contact each other through them when pressure is applied, thereby achieving electrical connection.

[0034] The controller is an electronic control unit that monitors and processes the signals from the lower conductive components and the upper conductive components. It can identify when an electrical connection has occurred and generate corresponding warning or alarm signals accordingly. Optionally, the controller can also perform additional functions, such as delay processing to reduce the occurrence of false alarms.

[0035] The electrical signal refers to the formation of a microcircuit loop and the generation of current when the upper and lower conductive components are pressed and contacted through the hollow area. This current change is converted into an electrical signal, which is received and analyzed by the controller.

[0036] The pressure warning signal means that once the controller detects a valid electrical connection event (i.e. a real pressure change rather than a false touch), it will generate a pressure warning signal. This signal will then be sent to the receiving host alarm, which will activate the appropriate alarm mechanism based on the received information, such as sound, flashing light or vibration prompt.

[0037] Specifically, first, it is composed of an upper conductive component and a lower conductive component, and a layer of insulating foam with regular hollow areas is sandwiched between the two layers, which together constitute the core component of the care monitoring equipment, namely the "pressure sensing pad". Secondly, connected to the "pressure sensing pad" is the controller, which is responsible for receiving the electrical signal from the "pressure sensing pad", processing the electrical signal and converting it into a pressure warning signal. Optionally, in order to improve the accuracy and reliability of the care monitoring equipment, the controller has a built-in algorithm to identify and filter out false touch signals in non-dangerous situations, such as false alarms caused by slight movements such as turning over and arm support.

[0038] In one example, when a user lies or sits on a bed, chair, or other position equipped with this care monitoring device, their body weight will be applied to the pressure sensing pad. If the user begins to move toward the bed or prepares to get up, part of the body weight will be transferred to the pressure sensing pad, causing the upper conductive components to contact the upper conductive components through the hollow area, forming a microcircuit loop and triggering an early warning signal (i.e., a pressure warning signal). If the user completely leaves the pressure sensing pad, the original microcircuit will be disconnected. At this time, the controller will detect this change and output a more urgent human body departure warning signal.

[0039] This care monitoring device not only directly solves the safety issues of the elderly and special groups at night or when they are alone, but also indirectly improves their quality of life, while providing more convenient and effective care methods for caregivers and family members. Through precise pressure sensing technology and intelligent signal processing, it provides efficient and reliable safety protection for people who need special attention. And further, for some guardians who still have a certain degree of self-care ability, this care monitoring device can provide the necessary protection without affecting their daily activities, helping them maintain a certain degree of independence.

[0040] Optionally, when the pressure applied by the human body to the upper conductive component disappears, the upper conductive component and the lower conductive component are electrically disconnected, and the controller generates a target warning signal after the electrical connection is disconnected.

[0041] The target warning signal is a more urgent signal than the pressure warning signal. It is different from the early warning signal, the pressure warning signal, which is triggered when the user starts to move to the bedside or prepares to get up, but has not completely left the pressure sensing mat. The target warning signal is activated when the user has left the pressure sensing mat, which means they may be trying to get up, fall, or leave the safe area.

[0042] Specifically, when a user lies or sits on a bed, chair or other position equipped with a nursing monitoring device, his body weight is applied to the pressure sensing pad. At this time, the upper conductive component and the lower conductive component inside the pressure sensing pad contact through the hollow area on the middle insulating foam to form a microcircuit loop.

[0043] If the user completely leaves the pressure sensing pad (for example, trying to get up, accidentally falling, or leaving the safe area), the pressure originally applied to the pressure sensing pad will disappear. Due to the loss of external pressure, the upper and lower layers of conductive components will separate under the natural tension of the foam, resulting in the original microcircuit loop being cut off, that is, the electrical connection is disconnected. This disconnection of the electrical connection will be detected by the controller, which will then output a more urgent target warning signal.

[0044] Because this mechanism can quickly respond to the user leaving the safe area. Once it detects that the user has moved away from the pressure sensing pad and the pressure disappears, a targeted warning signal is immediately generated to ensure that caregivers or family members can be notified as soon as possible and take necessary actions. This greatly improves the user's safety level, especially at night or when they are alone.

[0045] In one embodiment, the upper conductive component includes an upper conductive structure and an upper plastic structure, the upper plastic structure is located above the upper conductive structure, the lower conductive component includes a lower conductive structure and a lower plastic structure, the lower plastic structure is located below the lower conductive structure, and the upper plastic structure and the lower plastic structure are used to encapsulate the upper conductive structure, the lower conductive structure and the insulating component.

[0046] The upper conductive structure refers to a layer of conductive material located below the upper plastic structure, which can usually be made of a specially designed conductive carbon circuit printed on a polyethylene film or conductive aluminum foil. Its main function is to contact the lower conductive structure through the hollow area on the insulating foam in the middle when pressure is applied, forming a microcircuit loop.

[0047] The upper plastic structure refers to a layer of synthetic polymer plastic covering the upper conductive structure. Its purpose is to protect the internal conductive structure from the external environment and help encapsulate the entire sensor unit to ensure its durability and reliability.

[0048] The lower conductive structure refers to a layer of conductive material located above the lower plastic structure, which is usually a specially designed conductive carbon circuit printed on a polyethylene base film or conductive aluminum foil. It works with the upper conductive structure, and when the two are in contact due to external pressure, a complete circuit path is formed.

[0049] The lower plastic structure refers to the synthetic polymer plastic at the bottom layer, which covers the lower conductive structure. This structure not only plays a protective role, but also participates in the packaging process of the entire pressure pad to ensure the integrity and stability of the sensor.

[0050] Specifically, refer to Figure 1 The pressure sensing pad in the present application adopts a multi-layer composite structure to achieve efficient pressure monitoring. Specifically, it is composed of two groups of conductive components and insulating components: an upper conductive component, a lower conductive component and an insulating component.

[0051] The upper conductive component includes an upper conductive structure 101 (e.g., a specially designed conductive carbon circuit printed on a polyethylene film or conductive aluminum foil), and an upper plastic structure 102 (e.g., made of synthetic polymer plastic such as PVC or TPU) covering it. The upper conductive structure is responsible for forming a part of the circuit when under pressure; while the upper plastic structure provides physical protection and participates in the packaging process of the entire sensor.

[0052] The lower conductive component also includes a lower conductive structure 104 (made of the same material as the upper conductive structure) and a lower plastic structure 105 (also made of synthetic polymer plastic) located therebelow. The lower conductive structure works in conjunction with the upper conductive structure to complete circuit closure under appropriate conditions; the lower plastic structure not only plays a protective role, but also assists in overall packaging.

[0053] The insulating component 103 is a layer of insulating foam placed between the upper and lower conductive components, with regularly arranged hollow gaps on it. This component ensures that the upper and lower conductive components remain separated when no external force is applied, avoiding unnecessary current flow. At the same time, these hollow gaps allow the upper and lower conductive structures to contact under pressure, thereby forming a microcircuit loop.

[0054] The upper plastic structure and the lower plastic structure play a key role together, they tightly encapsulate the upper conductive structure, the lower conductive structure and the insulating components in the middle. This packaging method not only protects the internal components from the influence of the external environment, such as moisture, dust, etc., but also enhances the durability and reliability of the entire pressure sensing pad.

[0055] Due to the packaging design of the upper and lower layers of plastic structural parts, the key components inside the entire pressure sensing pad (such as conductive structural parts and insulating foam) are firmly fixed together. This packaging method not only enhances the integrity of the structure, but also effectively prevents the internal components from being displaced or damaged due to external factors (such as pulling or squeezing). Furthermore, the packaging process ensures the precise alignment between the conductive structural parts and the insulating foam, so that when subjected to external pressure, the upper and lower conductive structural parts can accurately contact through the hollow area on the foam and form a microcircuit loop. Conversely, in a pressure-free state, the two layers of conductive structural parts remain separated, thereby avoiding unnecessary current flow. This design ensures the accuracy of signal transmission and reduces the possibility of false alarms. ,

[0056] In one of the embodiments, the packaged upper conductive structure, insulating components and lower conductive structure are divided into two side areas and a central area. The two side areas are used to generate pressure warning signals, and the central area is used to generate target warning signals.

[0057] The two side areas refer to the parts located on the left and right sides of the pressure pad after the pressure sensing pad is packaged. It can be understood that the two side areas are specially designed to monitor whether the user starts to move toward the edge of the bed or the edge of the seat.

[0058] The central area refers to the main part of the center of the pressure sensing pad, which is usually placed under the core of the user's body, such as under the shoulders or hips. It is the most critical monitoring point in the entire system.

[0059] Specifically, after packaging, the upper conductive structure, insulating components and lower conductive structure inside the pressure sensing pad are clearly divided into three functional areas: the early warning area on both sides and the center departure alarm area. Understandably, this partition design is intended to provide accurate monitoring for different types of mobile behaviors and trigger corresponding warning signals.

[0060] The side zones are located on the left and right sides of the pressure pad, close to the edge of the bed or seat. These zones are mainly used to detect if the user starts to move towards the edge, such as when an arm or leg touches the zone. When these zones feel pressure, it means that the user may be preparing to get up or try to leave the safe position. The pressure warning signal is generated by the side zones. When the user's body (such as arms and legs) touches the side zones and applies a certain amount of pressure, even a slight change in pressure will trigger an early warning signal. This signal alerts caregivers or family members that the user may be trying to get up or leave the safe position so that they can intervene in advance to prevent potential risks.

[0061] The center area is located in the central part of the pressure pad and is usually placed under the core part of the user's body (such as shoulders or hips). This area is the focus of monitoring to determine whether the user has completely left the safe position. Once the user moves away from here, the applied pressure disappears, and the system will identify it as a potential risk event. The target warning signal is generated by the center area. When the pressure in the center area disappears (that is, the user has left the area), the electrical connection between the upper and lower conductive structures is disconnected, and the controller will recognize this change and delay the processing time for 3 to 5 seconds to confirm that the departure event has indeed occurred rather than a short-term action (such as turning over or arm support). If it is confirmed to be a real departure, a more urgent target warning signal will be generated, indicating that the user may have stood up, fallen, or left the safe area and needs immediate attention.

[0062] Since the pressure sensing pad is divided into two side areas and a central area, the care monitoring device can distinguish different user behaviors. The two side areas are mainly used to detect the user's behavior of moving toward the edge, triggering an early warning signal, namely the pressure warning model; while the central area focuses on monitoring more serious complete departure events and generates a more urgent target warning signal. This partition design improves the pertinence and accuracy of the warning.

[0063] In one of the embodiments, in the two side regions, the upper circuits of the upper conductive structure and the lower circuits of the lower conductive structure are arranged alternately to form a bridge-type series connection.

[0064] The upper circuit refers to the conductive path located inside the pressure sensing pad and on the upper conductive structure. It is composed of a specially designed conductive carbon line or conductive aluminum foil, and works with the lower conductive structure to form a microcircuit loop through the hollow area on the middle insulating foam under certain conditions (such as applying pressure).

[0065] The lower circuit refers to the conductive path located inside the pressure sensing pad and on the lower conductive structure. It is composed of a specially designed conductive carbon line or conductive aluminum foil, and works with the upper conductive structure to form a microcircuit loop through the hollow area on the middle insulating foam under certain conditions (such as applying pressure).

[0066] Bridge-type series connection refers to a special circuit connection method, and in this application, it refers to the staggered arrangement of the upper circuit and the lower circuit in the two side areas. Specifically, the circuit on the upper conductive structure is not directly opposite to the circuit on the lower conductive structure, but exists in a staggered arrangement, so that the two layers of circuits can only contact each other through the hollow gap on the middle foam to form an effective electrical connection when they are subjected to a sufficiently large area and continuous pressure.

[0067] Specifically, refer to Figure 2 , the circuits in the two side areas are designed to be staggered and bridge-type series. In the two side areas of the pressure sensing pad, the upper circuit on the upper conductive structure and the lower circuit on the lower conductive structure are not directly arranged opposite each other, but are staggered. This design ensures that even when the user's palm or other small objects briefly touch the surface of the pressure pad, the warning signal will not be easily triggered. It is precisely because of the staggered upper and lower circuits that the so-called bridge-type series connection is formed. The upper and lower circuits are not simply in face-to-face contact, but are in contact in a dislocated manner through the hollow area on the middle insulating foam. This means that the two layers of circuits can only contact each other through these hollow gaps to form an effective electrical connection when they are subjected to a sufficiently large and continuous pressure.

[0068] Due to the bridge-type series design, the nursing monitoring equipment can effectively filter out the slight pressure changes common in daily activities, avoiding unnecessary alarms. It also reduces system wear caused by frequent false triggering and extends the service life of the product.

[0069] In one of the embodiments, in the central region, the upper circuit of the upper conductive structure and the lower circuit of the lower conductive structure are aligned to form a contact series connection.

[0070] Among them, contact series connection means that in the central area of ​​the pressure sensing pad, the upper circuit on the upper conductive structure and the lower circuit on the lower conductive structure are aligned. This means that the upper and lower circuits are separated when there is no external force, but when subjected to appropriate pressure, the two circuits can directly contact and form an electrical connection. This connection method is called contact series connection.

[0071] Specifically, refer to Figure 2 , the circuit in the center area is designed to be aligned and connected in series with the contact type. In the center area of ​​the pressure sensing pad, the upper circuit on the upper conductive structure and the lower circuit on the lower conductive structure are aligned. This means that the upper and lower circuits are arranged in the same position and shape, ensuring that they can accurately contact each other when subjected to appropriate pressure.

[0072] In one example, reference Figure 1 Normally, in the absence of external pressure, the upper circuit and the lower circuit are separated, separated by a layer of insulating foam. At this time, the circuit is in a disconnected state and no current flows. However, when the user's body (such as shoulders or hips) applies enough pressure to the central area, the upper and lower circuits can directly contact each other through the hollow area on the middle insulating foam to form a complete microcircuit loop. This circuit connection method achieved through physical contact is called contact series connection. Once the user leaves the central area, the originally applied pressure disappears, and the upper and lower circuits will separate under the action of the natural tension of the foam, cutting off the electrical connection. The controller 106 detects this change in electrical connection and generates a target warning signal accordingly, indicating that the user may have stood up, fallen, or left the safe area.

[0073] Due to the contact series design, the nursing monitoring device can respond very sensitively to changes in the pressure in the central area. As long as the user leaves the area, causing the originally applied pressure to disappear, the alarm will be triggered immediately. Once a real leaving event is confirmed, the nursing monitoring device can quickly send out a targeted early warning signal to notify the caregiver or family member to take timely action to ensure the user's safety.

[0074] In one of the embodiments, the controller obtains the target time for the upper conductive component and the lower conductive component to disconnect the electrical connection, and when the target time is greater than a preset time threshold, the controller converts the electrical signals generated by the upper conductive component and the lower conductive component within the target time into a target warning signal.

[0075] The target duration refers to the time period from when the upper conductive component and the lower conductive component are disconnected electrically to when the controller detects this state change. In other words, the target duration is a period of time recorded by the controller during which the electrical connection between the upper and lower conductive components is disconnected.

[0076] The preset time threshold refers to a time limit preset by the care monitoring device to determine whether a user leaving event has actually occurred. It is a fixed reference time, for example, the preset time threshold is set to 3~5 seconds (the specific value can be adjusted according to actual needs).

[0077] Specifically, in the central area of ​​the pressure sensing pad, when the user leaves the central area, the originally applied pressure disappears, causing the electrical connection between the upper conductive component and the lower conductive component to be disconnected. At this point, the controller will begin to monitor and record the duration of this electrical disconnection, that is, the target duration. In order to distinguish short actions (such as turning over, arm support, etc.) from real leaving events, the nursing monitoring device will set a preset duration threshold, for example, the preset duration threshold is 3 to 5 seconds (the specific value can be adjusted according to actual needs). This preset duration threshold is used to determine whether a user leaving event has actually occurred.

[0078] The controller compares the recorded target duration with the preset duration threshold. If the target duration is less than or equal to the preset duration threshold, the controller considers that this may be a slight movement of the user and will not trigger the alarm. If the target duration is greater than the preset duration threshold, the controller confirms that this is a real departure event and converts the electrical signal during this period into a target warning signal. Once it is confirmed that the target duration is greater than the preset duration threshold, the controller will take the following actions, specifically: convert the electrical signals generated by the upper conductive component and the lower conductive component within the target duration into a target warning signal. And generate and send a target warning signal to the receiving host alarm to notify caregivers or family members to take necessary actions immediately, check the user's status and provide assistance.

[0079] By introducing a preset time threshold, the care monitoring device can distinguish between short actions (such as turning over, arm support, etc.) and real leaving events. The alarm will only be triggered when the electrical connection is disconnected for longer than the set threshold. This effectively reduces false alarms caused by daily activities and improves the reliability and user experience of the care monitoring device. This mechanism ensures that the care monitoring device only issues an alarm when the user actually leaves the central area, avoiding unnecessary interference, so that caregivers or family members can trust the prompts of the care monitoring device more.

[0080] The present invention also provides another technical solution: a nursing monitoring system, including a nursing monitoring device and an alarm device, the nursing monitoring device including an upper conductive component and a lower conductive component, an insulating component is arranged between the upper conductive component and the lower conductive component, the insulating component is provided with a hollow area, and one end of the upper conductive component and / or the lower conductive component is connected to a controller; when a human body applies pressure to the upper conductive component, the upper conductive component and the lower conductive component are electrically connected through the hollow area in the insulating component, and the controller is used to convert an electrical signal generated by the electrical connection into a pressure warning signal;

[0081] Nursing monitoring equipment, used to send pressure warning signals to alarm equipment;

[0082] The alarm device is used to receive the pressure warning signal and issue an alarm prompt based on the pressure warning signal.

[0083] As part of the nursing monitoring system, the alarm device is responsible for receiving the pressure warning signals from the nursing monitoring equipment and issuing corresponding alarm prompts based on these signals. Its main function is to alert caregivers or family members in various ways when potential risks are detected so that they can respond quickly.

[0084] Optionally, the alarm device is composed of one or more receiving host alarms, each of which can be paired with multiple pressure pad sensor transmitter controllers.

[0085] Optionally, the alarm device has multiple area indicator lights, and the user can define the representativeness of each indicator light as needed, so as to more clearly understand which area triggered the alarm.

[0086] Optionally, the receiving host alarm is compactly designed with a back clip, pendant or lanyard function, so it can be carried around, placed on a table or hung on a wall, ensuring that caregivers can receive alarm information in a timely manner no matter where they are.

[0087] Specifically, refer to Figure 3The care monitoring system in this application is intended to provide safety protection for people who are unable to move or need care (such as elderly people, severely bedridden patients, dementia patients and young children). The care monitoring system consists of two major parts: an alarm device 301 and a care monitoring device 302.

[0088] The nursing monitoring equipment consists of a conductive component, an insulating component and a controller. The upper conductive component and the lower conductive component are located on the upper and lower sides of the pressure sensing pad, respectively, and are composed of specially designed conductive carbon circuits or conductive aluminum foil. The insulating component is placed between the upper and lower conductive components, usually a layer of insulating foam with regularly arranged hollow areas on it, allowing the upper and lower conductive components to contact and form an electrical connection when pressure is applied. The controller is connected to one end of the upper or lower conductive component, responsible for monitoring the electrical connection status and converting the generated electrical signal into a pressure warning signal.

[0089] In one example, when the human body applies pressure to the upper conductive component, the upper and lower conductive components make physical contact through the hollow area in the insulating component to form an electrical connection. After the controller detects this electrical connection, it converts the electrical signal generated by it into a pressure warning signal.

[0090] The alarm equipment includes regional indicator lights, back clips and receiving host alarms. The alarm equipment can receive pressure warning signals from nursing monitoring equipment and issue corresponding alarm prompts based on these signals. There are multiple regional indicator lights on the receiving host alarm. Users can define the representativeness of each indicator light according to their needs, so as to have a clearer understanding of which area has triggered the alarm. The receiving host alarm is compact in design and has back clips and pendant lanyard functions. It can be carried with you, placed on a table or hung on the wall, ensuring that caregivers can receive alarm information in a timely manner no matter where they are.

[0091] In one example, when the user's body (such as the shoulder or hip) applies pressure to the central area of ​​the pressure sensing pad, the upper and lower conductive components contact through the hollow area in the insulating component to form an electrical connection. After the controller detects the electrical connection, it converts the resulting electrical signal into a pressure warning signal. The nursing monitoring device sends the pressure warning signal to the alarm device. The alarm device receives the pressure warning signal and activates the corresponding prompt mechanism (such as sound, flashing light or vibration) according to the setting to notify the caregiver or family member. The caregiver or family member takes necessary actions based on the alarm prompt, checks the user's status and provides assistance. By manually pressing the "Stop Alarm" button, the alarm device can be reset to restore the system to standby mode and continue monitoring.

[0092] The nursing monitoring system of this application achieves accurate monitoring and timely warning of potential risks through close cooperation between the nursing monitoring equipment and the alarm equipment. It not only improves the overall performance and reliability of the system, but also provides users with a safer, more stable and convenient monitoring solution. Such a design can provide timely help at critical moments and effectively reduce the risk of accidents, which is particularly suitable for those who need long-term monitoring.

[0093] In one of the embodiments, when the pressure applied by the human body to the upper conductive component of the nursing monitoring device disappears, the upper conductive component and the lower conductive component are electrically disconnected, and the controller generates a target warning signal after the electrical connection is disconnected; the nursing monitoring device is also used to send the target pressure warning signal to the alarm device; the alarm device is also used to receive the target warning signal and issue an alarm prompt based on the target warning signal.

[0094] Specifically, when the human body moves away from the monitoring area of ​​the pressure pad and the pressure applied to the upper conductive component disappears, the electrical connection between the upper conductive material (such as the conductive carbon circuit or conductive aluminum foil on the polyethylene base film) and the lower conductive component is disconnected due to the natural tension of the intermediate insulating foam. Once the disconnection of this electrical connection is detected, the built-in pressure pad sensor transmitter controller will generate a target warning signal. This signal indicates that the user may have left the safe monitoring area, such as accidentally falling from a bed, chair or wheelchair.

[0095] The target warning signal is transmitted to the receiving host alarm by wireless or wired means. After receiving the target warning signal, the receiving host alarm will identify the signal type according to the pre-set specific code and activate the corresponding alarm mechanism. The receiving host alarm has three prompt modes: sound, flashing light and vibration to ensure that no matter what the caregiver or family member is in (such as sleeping or having sensory impairment), they can be notified and respond in time.

[0096] Through the above steps, the care monitoring equipment is responsible for monitoring the user's status changes and sending early warning signals, while the alarm device receives these signals and performs corresponding alarm actions, thus forming a complete monitoring and alarm system aimed at ensuring the safety of the user and assisting the caregiver in effective monitoring.

[0097] In one embodiment, the alarm device includes multiple area indicator lights, each area indicator light is paired with a nursing monitoring device, and the alarm device is also used to convert the target early warning signal received from the nursing monitoring device into a prompt signal according to a pre-set alarm prompt method, and the prompt signal is used to make an alarm prompt according to the pre-set alarm prompt method.

[0098] Among them, the area indicator light refers to the visual prompt component installed on the receiving host alarm. Each indicator light corresponds to a specific receiving host alarm, and a nursing monitoring device can include multiple receiving host alarms. These indicators are used to intuitively display which specific monitoring device has issued a warning or alarm signal. Users can define the specific location or person represented by each indicator light according to their needs. For example, one indicator light may correspond to the bed in the bedroom, and another to the chair in the living room, etc.

[0099] The alarm prompt mode refers to the way the host alarm is used to notify the caregiver or family member. In this application, the care monitoring device is designed with three different prompt modes: sound (auditory), flashing light (visual) and vibration (tactile). This ensures that the user can receive the alarm information regardless of whether they have hearing or visual impairments, or do not want to be disturbed during the night. Caregivers or family members can choose the alarm prompt mode that best suits their environment and personal preferences.

[0100] The prompt signal is the actual output generated by the receiving host alarm based on the target warning signal received from the nursing monitoring device. This signal will be converted according to the pre-set alarm prompt method and conveyed to the caregiver or family member through the corresponding prompt method (such as sound, flashing light or vibration). The prompt signal is designed to attract attention and prompt relevant personnel to take action to check or help the person being monitored.

[0101] Specifically, the alarm device is designed with multiple zone indicator lights, each of which is paired with a receiving host alarm. This means that each pressure pad in different locations such as a bed, a chair or a wheelchair can be associated with an independent indicator light on the receiving host alarm through its unique coding. The user can customize the specific location or person represented by these indicator lights to clearly identify which area has a warning or alarm event. Optionally, the alarm device includes a working / low power LED indicator light 401, a zone indicator light 402, a stop button 403, a pairing button 404, a buzzer 405, a volume button 406, a power switch 407 and a back clip 408.

[0102] When the receiving host alarm receives the target warning signal transmitted from the nursing monitoring device, it will convert the target warning signal into an appropriate prompt signal according to the preset alarm prompt method. The alarm prompt methods here include but are not limited to sound (auditory), flashing lights (visual) and vibration (tactile) to ensure that caregivers or family members can be notified in time regardless of the situation. The converted prompt signal is used for alarm prompt according to the preset alarm prompt method.

[0103] In one example, if the target warning signal indicates that the user may have left the safe area, the receiving host alarm may issue a rapid sound alarm, and the corresponding area indicator light begins to flash; if it is an early warning signal, it may be a gentle sound or only the indicator light turns on. In this way, caregivers or family members can respond quickly according to different prompt signals, check and assist the person being cared for, and effectively prevent potential safety risks.

[0104] Since multiple zone indicator lights are paired one-to-one with care monitoring devices in different locations, caregivers or family members can quickly determine which specific device has issued a warning or alarm signal. This helps to quickly locate the location of the incident, such as which bed or chair user has an abnormal situation, thereby improving response efficiency. And according to different user needs and environmental conditions, the most appropriate alarm prompt method (sound, flashing light, vibration) can be selected to ensure that even with hearing or visual impairments, it can be effectively notified. In addition, at night or in a quiet environment, you can choose vibration or light prompts in silent mode without affecting the rest of others.

[0105] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
