Description

Technical Field

[0001] This invention relates to the field of medical smart wearable devices, and in particular to a chest-mounted smart medical watch and its control method. Background Technology

[0002] Existing ward call systems typically include a call button at the patient's bedside, a main unit at the nurse's station, and a mobile receiving terminal carried by medical staff. When a patient presses the call button, the main unit at the nurse's station emits a prompt tone, while the mobile receiving terminal alerts medical staff by vibrating or beeping.

[0003] However, existing technologies have the following drawbacks: medical staff need to wear timing tools (such as watches or stopwatches) and call receiving devices separately during clinical work. These devices are scattered, inconvenient to carry, and prone to missing call information. Mobile receiving terminals can usually only emit vibrations or beeps to alert patients and cannot display the specific bed number that initiated the call. After receiving the alert, medical staff still need to verify the patient information through other means, which affects response efficiency. In addition, existing receiving terminals do not have intercom functions, so medical staff cannot confirm the needs with patients before rushing to the ward, resulting in unnecessary round trips and increasing workload. Especially at night, the loud beeping volume can easily disturb patients' rest and affect their medical experience.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0018] This application provides a method and related equipment for robot emotion expression. To make the purpose, technical solution, and effects of this application clearer and more explicit, the following detailed description is provided with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0019] It will be understood by those skilled in the art that, unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0020] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature 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.

[0021] The preferred embodiment of the present invention describes a chest-mounted smart medical device, such as... Figure 1 As shown, the chest-mounted smart medical watch includes: a watch body, a chest-mounting buckle located above the watch body, and a display screen located below the watch body, wherein the chest-mounting buckle, the watch body, and the display screen are connected in sequence; The chest clip is used to hang the main body of the watch on the chest of the medical staff, so that the display screen is kept within the medical staff's line of sight. The main body of the hanging meter is used to establish a wireless connection with the ward patient call system, receive call signals initiated by patients in real time, trigger an alert after receiving the call signal, generate corresponding patient bed number information based on the call signal, and send the patient bed number information to the display screen; The display screen is used to display the patient's bed number information in real time when the main body of the hanging meter triggers the reminder, so that the medical staff can directly obtain the patient's bed number that initiated the call from the display screen within their line of sight.

[0022] Understandably, this invention designs a chest-mounted timer that integrates timing (time display + timing), call linkage reminders, bed number visualization, and two-way intercom functions. It seamlessly connects with existing ward patient call systems, achieving multiple uses in one timer, simplifying the wearing of equipment by medical staff, and improving call response efficiency and the convenience of nursing work. The main body of the timer features a lightweight and waterproof design, equipped with a chest-mounted buckle (for easy hanging on the chest by medical staff); the front has a display screen supporting regular time display and stopwatch timing (start, stop, and reset functions), meeting basic clinical timing needs. The timer display screen can display the patient's bed number / code that initiated the call in real time, continuously displaying it until the call signal is cleared, eliminating the need for secondary verification by medical staff and directly and accurately locating the called ward / bed.

[0023] Furthermore, the main body of the wall-mounted meter includes: a wireless communication module, a reminder module, and a processing chip; The wireless communication module is used to establish a wireless connection with the ward patient call system and receive call signals initiated by patients; The reminder module is connected to the wireless communication module and is used to continuously send reminders to the medical staff when the call signal is received, until the medical staff confirms. The processing chip is connected to the wireless communication module and the display screen respectively, and is used to generate corresponding patient bed number information according to the call signal, and send the patient bed number information to the display screen.

[0024] In this embodiment, the main body of the wall-mounted meter integrates a wireless communication module, a reminder module, and a processing chip. The wireless communication module establishes a wireless connection with the ward's patient call system, receiving call signals initiated by patients via the bedside call button in real time. When a patient presses the call button, the call signal is forwarded by the ward call system's host, captured by the wireless communication module, and transmitted to the processing chip.

[0025] The reminder module is electrically connected to the wireless communication module and is used to continuously remind medical staff when the wireless communication module receives a call signal. The reminder includes a yellow light prompt and / or an audio prompt. The reminder module continues to operate until the medical staff confirms receipt of the call by operating the buttons or touch screen, avoiding missed calls due to brief reminders.

[0026] The processing chip is electrically connected to both the wireless communication module and the display screen. The processing chip receives call signals transmitted by the wireless communication module, parses the call signal to determine the patient's bed number, and sends this information to the display screen for real-time display. Medical staff can attach the main body of the monitor to their chest using a chest clip, allowing them to directly view the patient's bed number on the display screen within their line of sight, without needing to return to the nurses' station or check other equipment.

[0027] In this embodiment, the wireless communication module, the reminder module, and the processing chip can be integrated on the same circuit board to reduce the size of the main body of the wall clock and achieve a lightweight design. The processing chip can also simultaneously control the time display function of the screen, ensuring that the timing function and the call response process operate in parallel without interference.

[0028] Furthermore, the reminder module includes a light-emitting unit, a sound-emitting unit, and a vibration unit; The light-emitting unit is disposed on the edge or back of the display screen and is used to emit a weak yellow light with a wavelength of 590-620nm as a reminder; The sound-emitting unit is located inside the main body of the wall-mounted meter and is used to emit a sound reminder with a volume adjustment range of 20-35dB. The vibration unit is located inside the main body of the watch and is used to emit vibration alerts.

[0029] It is understood that the reminder module is integrated inside the main body of the watch and includes a light-emitting unit, a sound-emitting unit, and a vibration unit. The three are electrically connected to the processing chip and are used to issue multi-dimensional reminders to medical staff when a call signal is received.

[0030] The light-emitting unit is located on the edge or back of the display screen and employs a diffuse reflection light-emitting structure to emit a weak yellow light with a wavelength of 590-620nm for alerts. This wavelength range of yellow light has strong penetrating power and soft illumination, allowing for clear visibility in both bright and dim environments in the ward. It does not generate heat or irritate the eyes, avoiding interference with clinical procedures. The light-emitting unit can be set to a constant-on mode or flash slowly at a frequency of 1-2 times per second until medical staff confirm receipt of the call.

[0031] The sound-emitting unit is located inside the main body of the wall-mounted meter and is used to emit an audible alert with a volume range of 20-35dB. This volume range is equivalent to a soft whisper, which can effectively alert medical staff in noisy ward environments without disturbing patients' rest. The sound-emitting unit supports multiple volume levels, which medical staff can set according to the noise environment of their department. It can also be used in conjunction with an intermittent beeping mode to enhance the recognizability of the alert.

[0032] The vibration unit is located inside the main body of the watch and is used to emit vibration alerts. The vibration unit can be activated independently when the sound unit is inconvenient to use, or it can work in conjunction with the light-emitting unit and the sound unit to form a triple alert mechanism, ensuring that medical staff will not miss any calls under any working conditions.

[0033] In this embodiment, the light-emitting unit, sound-emitting unit, and vibration unit are simultaneously triggered upon receiving a call signal and continue to operate until medical staff confirm receipt of the call via a button or touchscreen. This organic combination of three reminder methods not only meets the reminder needs of different work scenarios but also fully considers the special characteristics of the ward environment, reflecting a human-centered design philosophy.

[0034] Furthermore, when the processing chip triggers the reminder module to issue a reminder, it controls the light-emitting unit to flash at a preset frequency and controls the sound-emitting unit to simultaneously emit intermittent reminder sounds until the processing chip receives a call cancellation signal.

[0035] In this embodiment, the processing chip, as the core control unit of the watch body, is electrically connected to the light-emitting unit, sound-emitting unit, and vibration unit of the reminder module, and is used to uniformly schedule the working status of the reminder module. When the wireless communication module receives a patient call signal forwarded by the ward call system, the processing chip immediately generates a reminder trigger command and controls each reminder unit to work collaboratively according to a preset strategy.

[0036] When the processing chip triggers the reminder module to issue a reminder, it first controls the light-emitting unit to flash at a preset frequency. The preset frequency is a slow flashing mode of 1-2 times per second. This frequency can create a clear visual warning effect while avoiding discomfort caused by high-frequency flashing. At the same time, the processing chip controls the sound-emitting unit to emit intermittent reminder sounds. The intermittent reminder sounds are short beeps, each lasting 0.2 seconds and repeating at 0.5-second intervals (which can be adjusted as needed), keeping them synchronized with the flashing frequency of the light-emitting unit to create a visual and auditory reminder effect. The call cancellation signal can be generated by medical staff by pressing the multi-function button (call confirmation button) on the side of the monitor, touching the confirmation icon on the display screen, or automatically after the intercom ends. Before the processing chip receives the call cancellation signal, the reminder module continues to maintain the flashing of the light-emitting unit and the sound emission of the sound unit to ensure that medical staff do not miss calls due to brief reminders.

[0037] Understandably, the processing chip also supports personalized reminder mode settings. Medical staff can select, based on departmental characteristics, to activate either a combined reminder using only the light-emitting and sound-emitting units, or simultaneously activate the vibration unit to create a third reminder, via function buttons or the touchscreen. The processing chip executes the corresponding reminder strategy according to the preset configuration. The slow flashing frequency of the light-emitting unit and the beeping interval of the sound-emitting unit can also be adjusted according to actual clinical needs. The processing chip's built-in storage unit is used to save these settings.

[0038] In this embodiment, the main body of the hanging watch integrates a microphone, a speaker, and an intercom chip. The microphone, speaker, and intercom chip are electrically connected to the processing chip to realize two-way intercom, which is used to realize real-time voice communication between medical staff and patients.

[0039] The microphone is located on the side or lower front of the main body of the watch, with its pickup hole facing the mouth of the medical staff to pick up their voice signals. When the medical staff presses the intercom answer button, the microphone starts working, converting the picked-up analog voice signal into an electrical signal and transmitting it to the intercom chip.

[0040] The intercom chip is a dedicated voice processing chip with a built-in analog-to-digital converter, audio codec, and signal amplifier. After receiving the voice signal from the microphone, the intercom chip first performs analog-to-digital conversion and noise reduction to remove ambient noise. Then, it encodes and compresses the processed digital voice signal and sends it to the ward patient call system via the wireless communication module. The ward patient call system forwards the received voice signal to the corresponding patient call terminal, where it is played back through the speaker, enabling medical staff to transmit their voices to patients.

[0041] The intercom chip operates in a two-way receiving mode, receiving patient voice signals relayed from the patient call system via the patient call terminal. After the patient speaks through the microphone on the call terminal, the voice signal is transmitted via the patient call system to the wireless communication module of the main unit of the wall-mounted meter. The wireless communication module then transmits the received signal to the intercom chip. The intercom chip decodes, converts digital to analog, and amplifies the received signal before transmitting the analog voice signal to the speaker.

[0042] The speaker is located inside the main body of the monitor, with its sound outlet located on the side or back of the monitor body. After receiving the patient's voice signal transmitted by the intercom chip, the speaker converts the electrical signal into an audio signal and plays it out for medical staff to hear.

[0043] Furthermore, the main body of the hanging meter also includes a rechargeable battery and a charging interface; The rechargeable battery is located inside the main body of the watch and is used to power the wireless communication module, the reminder module, the processing chip and the display screen; The charging interface is located on the side or back of the main body of the watch and is connected to the rechargeable battery for connecting to an external power source.

[0044] In this embodiment, the main body of the hanging meter is equipped with a rechargeable battery and a charging interface. The rechargeable battery and the charging interface are electrically connected to the processing chip to provide a stable power supply for the various functional components inside the hanging meter.

[0045] The rechargeable battery uses high-energy-density cells and is located in the center of the main body of the watch to maintain overall weight balance. When fully charged, the rechargeable battery can provide power for more than 24 hours continuously to meet the daily work needs of medical staff. The rechargeable battery is electrically connected to other power-consuming modules or components, intelligently distributing power to each component. When the wireless communication module is in standby mode, the power management unit automatically reduces its power consumption; when the reminder module is triggered, the rechargeable battery prioritizes powering the light-emitting unit, sound-emitting unit, and vibration unit to ensure reliable execution of the reminder function.

[0046] The charging interface is located on the side or back of the main body of the wall-mounted meter, using a Type-C interface or a magnetic contact interface, and is electrically connected to the rechargeable battery. The rechargeable battery in this embodiment supports fast charging to adapt to the fast-paced work and fragmented charging time of medical staff in clinical settings. A waterproof sealing ring is provided around the charging interface, working in conjunction with the IP65 waterproof structure of the main body of the wall-mounted meter to prevent liquid from seeping into the internal circuitry during clinical handwashing and disinfectant spraying. The rechargeable battery also has a built-in temperature monitoring sensor; when an abnormally high battery temperature is detected, the processing chip automatically cuts off the charging circuit or limits the discharge power to ensure safe use.

[0047] Furthermore, the main body of the watch also has a stopwatch timing chip inside. The stopwatch timing chip is independent of the processing chip or integrated into the processing chip and is electrically connected to the processing chip and the display screen to provide medical staff with the stopwatch timing function required for clinical operations.

[0048] In this embodiment, the main body of the watch also has a stopwatch timing chip inside. The stopwatch timing chip is independent of the processing chip or integrated into the processing chip and is electrically connected to the processing chip and the display screen. It is used to provide medical staff with the stopwatch timing function required for clinical operations.

[0049] The stopwatch timing chip incorporates a high-precision crystal oscillator circuit, achieving a timing accuracy of 0.1 seconds, meeting the time precision requirements of clinical operations such as infusion rate measurement, pulse counting, and respiratory rate measurement. The stopwatch timing chip is connected to the start / stop button on the side of the watch body, receiving button commands through a processing chip. When a medical staff member presses the start / stop button, the processing chip sends a start command to the stopwatch timing chip, which begins timing and transmits the timing data to the display screen in real time. The display screen dynamically displays the elapsed time in digital form. Pressing the same button again stops the timing chip and locks the current timing value for medical staff to record. Pressing the reset button resets the timing value to zero, preparing for the next timing operation.

[0050] When the stopwatch timing chip and the processing chip work together, they support parallel processing mode. That is, while the stopwatch timing chip is performing its timing function, the processing chip can still receive call signals from the wireless communication module, trigger reminders from the reminder module, control the display of bed number information, and activate the two-way intercom function. The stopwatch timing and call response workflows do not interfere with each other, ensuring that medical staff do not miss patient calls while focusing on clinical procedures.

[0051] The stopwatch timing chip also has a built-in temporary storage unit that can temporarily store the most recent timing data. If medical staff interrupt the timing due to an emergency during operation, the temporary storage unit automatically saves the current timing value. Timing can resume or historical data can be retrieved after the emergency is resolved. The temporary storage unit can store a preset number of timing data sets, which medical staff can retrieve cyclically using function keys.

[0052] The stopwatch timing chip supports multiple timing modes, including forward timing (accumulating time from zero) and countdown timing (setting a reminder after a preset time). In countdown mode, medical staff can preset the countdown duration via function buttons. The stopwatch timing chip then begins the countdown. When the countdown reaches zero, it sends a signal to the processing chip, which triggers the reminder module to emit a short beep, alerting the medical staff that the timer has ended. This function is particularly suitable for clinical scenarios such as infusion drip rate monitoring and aseptic operation time limit control.

[0053] Furthermore, the display screen is a high-definition touch screen or a button-type narrow-bezel screen, used to display time information and patient bed number information, wherein the patient bed number information is displayed in enlarged font; One side of the display screen is provided with an intercom button, which includes an intercom answer button and an intercom hang-up button; The other side of the display screen is provided with a multi-function button, which includes a call confirmation button, a volume adjustment button, and a brightness adjustment button.

[0054] In this embodiment, the display screen is located on the lower front of the main body of the watch, employing a high-definition touchscreen or a button-type narrow-bezel screen to intuitively present various information to medical staff. The core display content includes time information and patient bed number information. The time information is displayed in a conventional digital clock format, showing hours, minutes, and seconds, meeting the daily time-keeping needs of medical staff. When a patient call signal is received, the processing chip sends the parsed patient bed number information to the display screen, which automatically switches display modes to highlight the bed number with enlarged font, for example, displaying "Bed 8" in a size 2 or larger font in the central area of ​​the screen, facilitating quick identification by medical staff while moving.

[0055] Two intercom buttons are located on one side (left side) of the display screen: an intercom answer button and an intercom hang-up button. The intercom answer button activates the two-way intercom function upon receiving a call notification. When a medical staff member presses this button, the processing chip wakes up the intercom chip and activates the microphone and speaker, establishing a voice channel with the patient's call device. The intercom hang-up button ends the call. Pressing it deactivates the intercom chip and voice channel, and the display returns to standby mode. The two buttons are distinguished by different shapes or tactile feedback, allowing medical staff to easily identify and operate them via touch without visual inspection.

[0056] On the other side (right side) of the display screen, there is a multi-function button. The multi-function button is a single press button that can achieve different functions by short press, long press or combination of presses, so as to reduce the number of buttons and keep the main body of the wall clock simple and compact.

[0057] Specifically, the functions integrated into the multi-function button include: Call confirmation button function: When a call reminder is received, medical staff can press the multi-function button briefly. The processing chip receives the call confirmation signal and immediately stops the reminder module from emitting light, sound and vibration. At the same time, the call status is marked as "processed". However, the bed number information is still retained on the display screen until the medical staff arrives at the ward and completes the process. Then, the button is pressed again to cancel the status.

[0058] Volume adjustment button function: In standby mode, medical staff can press and hold the multi-function button to enter the volume adjustment mode. The display screen will pop up the volume adjustment interface. At this time, short press the button to cycle through the volume of the reminder sound and the conversation voice. The adjustment range is 20-35dB. After selecting, press and hold again to confirm and exit.

[0059] Brightness adjustment button function: In standby mode, medical staff can press the multi-function button twice to enter the brightness adjustment mode. The brightness of the display screen can be adjusted to adapt to the strong light during the day and the dim light at night in the ward, so as to avoid the display screen being too bright and disturbing the patient's rest.

[0060] The stopwatch starts and stops automatically when the device is in standby mode. A short press of the multi-function button starts the stopwatch, and the display switches to the timing interface to show the elapsed time. A short press again stops the timer and locks the value. A long press for 3 seconds clears the timing data. If a call is received during the timing process, the processing chip automatically pauses the timing interface display and prioritizes displaying the bed number, while simultaneously triggering an alert. After handling the call, the medical staff can return to the timing interface to continue timing.

[0061] Countdown preset button function: In standby mode, medical staff can enter the countdown preset mode by pressing the multi-function button three times consecutively. Each short press cycles through the preset duration (e.g., 30 seconds, 1 minute, 3 minutes, 5 minutes, etc.). After selecting, a long press confirms and starts the countdown. When the countdown reaches zero, the processing chip triggers the reminder module to emit a short beep, reminding medical staff that the operation time has ended.

[0062] Furthermore, the intercom button and the multi-function button are covered with medical-grade silicone material, which is non-slip and waterproof. The buttons have a moderate travel and clear tactile feedback, ensuring accurate operation even when medical staff are wearing gloves. The button layout adopts a left-right split design, with a dedicated call control button on the left and an integrated function button on the right, which is ergonomic and easy to operate with one thumb. All buttons are electrically connected to the processing chip, which identifies different pressing methods according to preset logic and executes corresponding instructions, realizing multiple uses for a single button and maximizing the expansion of the watch's functionality within a limited space.

[0063] Furthermore, the chest-hanging buckle is a clamping or hanging structure, and the chest-hanging buckle is fixedly connected to the upper end of the watch body.

[0064] In this embodiment, the chest-mounted buckle is located on the upper end of the watch body and adopts a clamping or hanging structure. It is fixedly connected to the upper end of the watch body to securely hang the watch body on the chest of medical staff and ensure that the display screen is always within the medical staff's line of sight.

[0065] The clip-on chest hanger buckle includes an elastic clip and an anti-slip pad. The elastic clip is made of stainless steel or high-strength engineering plastic, possessing appropriate elasticity and clamping force, and can be clipped to the edge of the pocket, the inside of the collar, or the name tag strap of the medical staff's work clothes. The anti-slip pad, made of silicone or rubber, is located on the inside of the elastic clip, increasing friction with clothing and preventing the watch from slipping or shifting when the medical staff bends over, walks quickly, or performs clinical procedures. The clip-on structure is suitable for situations where work clothes with pockets or thick collars are worn, allowing medical staff to put on and take off the watch with one hand.

[0066] The attachable chest strap buckle includes a hook and a loop. The hook is located at the top of the strap body and is either a horizontally running strip or a round hole, with a diameter adapted to the width of a standard chest badge lanyard or name tag strap. The hook is an independent metal or plastic hook-shaped structure, with one end connected to the hook and the other end attached to the medical staff's chest badge lanyard or special strap. The attachable structure is suitable for scenarios where medical staff are accustomed to wearing chest badge lanyards. The strap body is directly threaded through the hook through the hook or connected to the lanyard via the hook, ensuring a stable wearing position without swaying with body movement.

[0067] Furthermore, the wearing height of the chest-mounted buckle of this invention is ergonomically designed. When the main body of the watch is hung on the chest via the chest-mounted buckle, the display screen is located approximately a preset distance (generally 5-10 cm) below the collarbone of the medical staff. This position does not affect the medical staff's ability to perform clinical operations such as intravenous puncture and wound dressing while looking down, and allows for quick scanning of the display screen content when the medical staff looks up or straight ahead. The connection point between the chest-mounted buckle and the main body of the watch is located at the upper center, allowing the main body of the watch to hang naturally and vertically, with the display screen always facing the front of the medical staff, preventing the display screen from turning to the side due to a shift in the center of gravity.

[0068] Furthermore, such as Figure 2 As shown, based on the above-mentioned chest-mounted intelligent medical care monitor, the present invention also provides a control method for the chest-mounted intelligent medical care monitor, wherein the control method includes: Step S10: Establish a wireless connection between the main body of the meter and the ward call system through the wireless communication module inside the meter body, and receive the call signal initiated by the patient through the wireless communication module.

[0069] Specifically, the wireless communication module within the main unit of the meter first establishes a wireless connection with the ward call system. The wireless communication module uses one of the following communication methods: Bluetooth, 4G, or a dedicated hospital local area network, to pair with the ward call system host deployed at the nurses' station or computer room. After the connection is established, the wireless communication module enters a low-power standby state, continuously monitoring signals emitted by the ward call system.

[0070] When a patient presses the call button at the bedside in the ward, the call signal is identified and processed by the ward call system host, and then forwarded in real time via the wireless network to the corresponding call device of the responsible medical staff. Upon receiving the call signal, the wireless communication module immediately transmits the signal data to the processing chip, while simultaneously waking up other functional components in the call device that are in low-power mode, preparing to execute subsequent response operations. A two-way authentication mechanism is used between the wireless communication module and the ward call system to ensure that only authorized call devices can access the system, preventing signal interference or misreception.

[0071] Step S20: Generate the corresponding patient bed number information based on the call signal using the processing chip inside the main body of the hanging meter.

[0072] Specifically, after receiving the call signal from the wireless communication module, the processing chip immediately initiates the signal parsing process. The call signal data packet contains information such as the patient's bed number code, the call timestamp, and the call type. The processing chip's built-in decoding algorithm parses the received data packet, extracts the patient's bed number code field, and converts the code into a readable bed number information format, for example, converting the code "8" into "Bed 8" and adding a ward area identifier. The processing chip also verifies the integrity and accuracy of the data, ensuring that the generated bed number information corresponds one-to-one with the patient initiating the call, avoiding incorrect bed number display due to signal interference. After parsing, the processing chip temporarily stores the patient's bed number information in its built-in cache, ready to send it to the display screen.

[0073] Step S30: Send the patient's bed number information to the display screen below the main body of the meter for display, and trigger the reminder module in the main body of the meter to issue a reminder through the processing chip.

[0074] Specifically, the processing chip sends the generated patient bed number information to the display screen located below the main body of the monitor via an internal data bus. Upon receiving the bed number information, the display screen automatically switches its display mode, enlarging the font to highlight the bed number in the center of the screen, for example, displaying "Bed 8" in size 2 font, while simultaneously displaying the time information in smaller print in the corner of the screen, ensuring that medical staff can quickly identify the source of the call while on the move. At the same time, the processing chip sends a trigger command to the reminder module, activating a multi-reminder mechanism. The light-emitting unit in the reminder module emits a weak yellow light with a wavelength of 590-620nm flashing at a frequency of 1-2 times per second, while the sound unit simultaneously emits intermittent beeping sounds of 20-35dB, and the vibration unit generates synchronized vibrations. The reminder module continues to operate until the processing chip receives a call confirmation signal from medical staff via function keys or the touchscreen, ensuring that medical staff do not miss any calls under any working conditions.

[0075] In summary, the core working principle of the smart call clock provided by this invention is as follows: a stable connection is established with the ward patient call system host via a wireless communication module, and it is in real-time standby mode; after the patient presses the bedside call button, the call signal is synchronously sent to the call clock of the corresponding responsible medical staff via the host; after receiving the signal, the call clock immediately triggers a weak yellow light that is constantly on / flickering and a soft beeping sound to remind the patient, while the display screen automatically pops up and continuously displays the bed number of the patient who initiated the call; medical staff can answer the intercom through the buttons on the call clock to communicate with the patient in two directions and confirm the needs; after the medical staff arrive at the ward to handle the situation, they can cancel the call reminder by pressing the button, and the call clock returns to standby mode; the call clock can simultaneously realize the functions of regular timekeeping and clinical operation timing (such as infusion timing, operation timing), and each module works independently without interference.

[0076] The present invention has the following beneficial effects: (1) For medical staff: One form integrates multiple functions, reducing the number of devices to carry, simplifying the workflow, and improving the ease of wearing; accurate bed number display + double reminders reduce the risk of missed calls and incorrect bed number verification; the front intercom function reduces unnecessary round trips and improves the efficiency of nursing work.

[0077] (2) For medical institutions: There is no need to modify the existing ward call system, the modification cost is low and it is easy to promote; improve the overall call response efficiency, optimize the nursing service process, and improve the quality of nursing services in medical institutions.

[0078] (3) For patients: It enables rapid transmission and accurate response to call requests, and two-way communication can quickly confirm the request, reduce waiting time, and improve the patient's medical experience.

[0079] In summary, this invention provides a chest-mounted smart medical watch and its control method. The smart watch includes: a watch body, a chest-mounted buckle located above the watch body, and a display screen located below the watch body. The chest-mounted buckle, watch body, and display screen are connected sequentially. The chest-mounted buckle is used to hang the watch body on the chest of medical personnel, keeping the display screen within their line of sight. The watch body is used to establish a wireless connection with the ward patient call system, receive call signals initiated by patients in real time, trigger an alert upon receiving the call signal, and generate corresponding patient bed number information based on the call signal, sending the patient bed number information to the display screen. The display screen is used to display the patient bed number information in real time when the watch body triggers an alert, allowing medical personnel to directly obtain the patient bed number initiating the call from the display screen within their line of sight. The smart watch provided by this invention integrates timing, call linkage alerts, bed number visualization, and two-way intercom functions. It seamlessly connects with existing ward patient call systems, achieving multiple uses with a single watch, simplifying the wearing of equipment by medical personnel, and improving call response efficiency and the convenience of nursing work.
