Description

Technical Field

[0001] The present invention relates to the field of medical care information technology, and in particular to a method and device for early warning of disease worsening by linking medical-nurse intercom with vital sign data. Background Art

[0002] In existing inpatient medical scenarios, patients' vital signs are usually continuously collected through a variety of monitoring devices, such as heart rate monitors, blood pressure monitors, and blood oximeters. When an indicator is abnormal, the system often alerts medical staff with sound and light alarms.

[0003] However, due to the heavy workload of nurses, limited ward rounds and fragmented alarm information, some potential deterioration risks are not responded to in a timely manner, thereby delaying the opportunity for intervention; on the other hand, there is a general lack of linkage mechanism between the existing monitoring system and the nursing communication system. Once an abnormality occurs, the system can only issue an early warning but cannot actively establish a communication channel between medical staff. Nurses often need to receive a prompt first and then find the patient's location one by one and go there in person to understand the situation. This passive response mode is particularly inefficient at night or when staff is short of staff, and can easily lead to delays in handling emergencies; in addition, patients in a dormant state are often unable to detect alarm prompts or nurse visits in time, especially elderly patients, postoperative patients or patients who are unconscious. Traditional alarm methods make it difficult to activate their active cooperation.

[0004] Therefore, there is an urgent need for an intelligent early warning system that can realize the integration of abnormal vital sign detection, medical and nursing intercom linkage, and patient automatic wake-up functions to improve clinical response efficiency and nursing safety. Summary of the Invention

[0005] The present invention aims to provide a method and device for warning of worsening of the condition by linking medical intercom with vital sign data, so as to solve the problems raised in the above-mentioned background technology. This solution breaks through the single response mode of traditional nursing mode that relies on sound and light alarms and passive rounds by nurses, and constructs an active linkage closed-loop system integrating real-time monitoring, intelligent identification, automatic wake-up, remote intercom, and data recording. Through real-time monitoring and intelligent analysis of the patient's vital sign data, the controller can automatically identify abnormalities in the early stage of the patient's condition worsening and respond in time. It not only sends an early warning to the nurse and automatically connects the voice intercom, but also wakes up the patient through a vibrating bracelet and graphic prompts, so that doctors and patients can communicate quickly without contact. The nurse can also judge whether to rush to the scene immediately based on this, greatly shortening the response time. It is particularly suitable for night duty or scenes with tight staffing, and significantly improves nursing efficiency, warning timeliness and patient safety.

[0006] In order to achieve the above object, the present invention provides the following technical solutions: A method for early warning of worsening of a condition by linking medical intercom with vital sign data includes the following steps: S1, real-time collection of patient vital sign data through monitoring devices; S2, the main controller analyzes the collected vital sign data to determine whether it reaches the preset abnormal threshold; S3: When an abnormality is detected, the controller performs the following linked operations: sends an early warning signal to the nurse's intercom terminal and automatically establishes a voice call; activates the vibration function of the patient's wristband to remind the patient; and plays the voice query input by the nurse on the intercom terminal to the patient in real time through the bedside speaker; At S4, the nurse inquires about the patient's status through the intercom and decides whether to go to the ward for rounds; S5, the controller records abnormal vital sign data, wake-up response, intercom results and other information.

[0015] Figure 1 A schematic diagram of the process provided by the present invention. DETAILED DESCRIPTION

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: like Figure 1 The illustrated method for warning of worsening of a condition by linking medical intercom with vital sign data includes the following steps: S1, real-time collection of patient vital sign data through monitoring devices; S2, the main controller analyzes the collected vital sign data to determine whether it reaches the preset abnormal threshold; S3: When an abnormality is detected, the controller performs the following linked operations: sends an early warning signal to the nurse's intercom terminal and automatically establishes a voice call; activates the vibration function of the patient's wristband to remind the patient; and plays the voice query input by the nurse on the intercom terminal to the patient in real time through the bedside speaker; At S4, the nurse inquires about the patient's status through the intercom and decides whether to go to the ward for rounds; S5, the controller records abnormal vital sign data, wake-up response, intercom results and other information.

[0017] In the current inpatient care process, although the patient's vital signs can be monitored in real time by a variety of devices, when abnormal signs appear, the early warning system usually only alerts medical staff through sound and light alarms, making it difficult to establish effective communication between doctors and patients in a timely manner; at the same time, nursing staff need to respond to alarms passively and go to the ward in person to understand the situation, which is inefficient, especially at night or when staff is tight, and it is easier to miss the best time for intervention. In addition, patients are often unable to detect alarm signals in time when they are asleep or in a state of blurred consciousness, resulting in an inability to cooperate with nurses' remote inquiries and evaluations. Therefore, there is an urgent need for a linkage early warning system that can integrate functions such as vital sign monitoring, nurse intercom, and patient awakening to improve clinical response efficiency and nursing safety. The proposed method for early warning of worsening conditions is an intelligent nursing response process based on the coordinated collaboration of vital sign data, nurse voice communication, and patient wake-up calls. While traditional hospital monitoring systems can monitor patient vital signs, they often only issue audible or visual alarms when an anomaly is detected. This approach is easily overlooked in noisy environments and fails to accurately assess the patient's current condition. This is especially true when patients are asleep or unconscious, and they may not even be aware of any abnormalities.

[0018] This solution first uses a monitoring device to continuously monitor the patient's vital signs (such as heart rate, blood pressure, body temperature, etc.), and transmits the data in real time to the controller for intelligent judgment. Once the controller detects that a patient's vital sign value exceeds the set safety range, the controller will immediately initiate the following three actions: 1. Calling a nurse: The controller will automatically send an early warning signal to the intercom at the nurse station and directly establish a voice call channel; 2. Wake up the patient: At the same time, the bracelet on the patient's hand begins to vibrate, gently reminding the patient to wake up and pay attention to the conversation; 3. The nurse speaks and the patient hears: When the nurse speaks on the intercom, her voice will be clearly played through the speaker at the patient's bedside, allowing the patient to hear the nurse's inquiries at the first time.

[0019] Next, the nurse can remotely ask the patient about their feelings or reactions via voice. If the situation is indeed critical or the patient is unable to respond, the nurse can quickly rush to the ward to intervene. The entire process can also be automatically recorded by the system, including vital signs data, whether the awakening is successful, the content of the call, etc., for subsequent tracking or medical decision-making. This method realizes an integrated closed loop of monitoring-early warning-interaction-recording, greatly improving nursing efficiency and safety.

[0020] A device for early warning of worsening of condition, which is linked to medical intercom and vital sign data, comprising: Monitoring device, which is used to collect data on various vital signs of patients; A controller, which is in communication with the monitoring device and is used to perform real-time analysis of vital sign data and generate an early warning signal when an abnormality is detected; Intercom device, which is used to automatically establish voice communication between patients and medical staff when the early warning signal is triggered; The wake-up device includes a vibrating bracelet worn on the patient's arm, which is used to issue a vibration prompt to wake the patient when the early warning signal is triggered, and assist the patient in identifying voice call behavior.

[0021] The monitoring device includes at least an electrocardiogram monitor, a blood oximeter, a blood pressure monitor, a body temperature sensor and a sleep state sensing module, and the monitoring data is transmitted to the controller via a wired manner.

[0022] The monitoring device in this solution uses multiple physiological monitoring instruments to work together. It can not only monitor basic vital signs (such as blood pressure, heart rate, blood oxygen saturation, etc.), but also determine whether the patient is in deep sleep or abnormal resting state through the sleep sensing module, facilitating a comprehensive assessment of the condition. The wired connection ensures stable and reliable data transmission and avoids data interruptions caused by wireless interference. It is suitable for medical-grade deployment scenarios in hospital wards.

[0023] The controller includes: A data acquisition module, the data acquisition module is used to receive vital sign data collected by the monitoring device; Data processing module, the data processing module is used to judge the received data; An abnormality identification module, which determines the worsening of the disease based on a preset threshold; The linkage control module is used to trigger the intercom device and the wake-up device at the same time after determining that the condition has worsened.

[0024] In this solution, the controller serves as the central processing unit, which integrates and analyzes the various vital sign data received. It can set personalized thresholds and use algorithms to determine whether the condition is worsening, ensuring that the trigger conditions are reasonable and effective. When an abnormality is identified, the linkage control module immediately issues a command to control voice calls, wake up devices, etc. with one click, reducing response delays and achieving true automatic early warning and closed-loop processing.

[0025] The intercom device includes a microphone and a speaker located at the patient's bedside, and an intercom terminal located at the nurse's station.

[0026] The intercom device in this solution adopts a two-way voice communication structure. The nurse can remotely initiate a conversation request through the terminal, and the microphone and speaker on the patient are automatically connected to achieve contactless communication. This design can improve interaction efficiency and is particularly suitable for patients with mobility difficulties after surgery. It helps medical staff understand the patient's self-report and state of consciousness before ward rounds.

[0027] The intercom device has an automatic connection function, which can automatically establish a call between the nurse terminal and the patient's bedside device without any operation.

[0028] The intercom device in this solution has an automatic connection mechanism. That is, after abnormal vital signs are identified, the controller can directly trigger the establishment of a call link without the need for manual operation by the patient or nurse, ensuring that doctor-patient communication is established in the first place. It is particularly suitable for scenarios such as patients being confused or sleeping deeply at night, significantly improving the speed and safety of early warning response. The bracelet is integrated with a heart rate sensor and an acceleration sensor to assist the monitoring device in monitoring the patient's condition and transmitting the data back to the main controller.

[0029] In this solution, the bracelet can not only serve as a wake-up device, but also as an auxiliary monitoring terminal to obtain information such as the patient's limb movement status and pulse rhythm. This information will be fused with the data from the main monitoring device to provide the controller with a more complete picture of the patient's status, further enhancing the accuracy of judgment on sudden changes in the disease.

[0030] The bracelet is connected to a display screen for displaying text or graphic prompts, including "Please pay attention to the conversation", "The condition is abnormal, please cooperate with the examination", etc., to assist patients in establishing communication with nurses through the intercom device.

[0031] In this solution, the bracelet display can be used to intuitively indicate the current status. Especially when the patient has limited hearing or the environment is noisy, graphic prompts can enhance the perception effect. Through short and clear prompts, patients can understand the current situation and the nurse's intentions, enhance the friendliness of human-computer interaction, and improve patient cooperation and system usability.

[0032] The above is only an embodiment of the present invention, and the common knowledge such as the specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the description can be used to interpret the content of the claims.
