Description

Technical Field

[0001] This invention belongs to the field of medical devices, and in particular relates to a system for monitoring vital signs and providing emergency call for patients in radiotherapy rooms. Background Technology

[0002] Radiotherapy is a crucial treatment for cancer, but traditional radiotherapy rooms typically employ lead shielding walls and enclosed protective doors to prevent radiation leakage, creating a closed environment with high radiation and strong electromagnetic shielding. This poses a significant challenge to real-time monitoring of patients' vital signs and emergency calls. In clinical practice, radiotherapy patients must be alone in the closed treatment room, while therapists observe their condition through conventional video monitoring in the adjacent operating room. This presents several safety hazards: First, conventional monitoring equipment cannot penetrate the electromagnetic shielding layer to transmit data, making it impossible to monitor key physiological indicators such as blood oxygen saturation and heart rate in real time, and hindering the early detection of risks such as sudden drops in blood oxygen or abnormal heart rate. Second, patients with fixed treatment positions, impaired consciousness (such as children under general anesthesia), or limited limb movement may have difficulty effectively transmitting distress signals in emergencies, and the enclosed environment also hinders sound transmission, potentially causing delays in rescue efforts. Third, existing monitoring equipment is mostly invasive or semi-invasive in design, which can easily interfere with the radiotherapy process and is unsuitable for the needs of critically ill or uncooperative patients. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a patient vital signs monitoring and emergency call system for radiotherapy rooms, comprising:

[0036] Example 1

[0037] like Figure 1-5 As shown, this embodiment provides a patient vital signs monitoring and emergency call system for radiotherapy rooms, including:

[0038] The patient wearable monitoring unit is used to non-invasively and continuously collect physiological data on the patient's fingertip blood oxygen saturation and heart rate, and can be triggered by the patient in an emergency to generate an emergency call signal;

[0039] An anti-interference transmission unit is communicatively connected to the patient-worn monitoring unit and is used to transmit the physiological data and the emergency call signal from the radiotherapy room to the operating room in real time.

[0040] The therapist terminal unit is communicatively connected to the anti-interference transmission unit, and is used to receive and parse the transmitted physiological data for display and storage, and to trigger an alarm when the emergency call signal is received.

[0041] Specifically, it includes:

[0042] The patient wearable monitoring unit includes:

[0043] 1. Flexible fingertip wearing body: Made of medical-grade silicone, it has the characteristics of radiation protection, hypoallergenic and flexible fit. It can adaptively adjust the tightness according to the size of the patient's fingertip. There is a breathable groove on the inside to reduce the stuffiness of wearing for a long time. The wearing area has reserved space for fingertip movement to ensure that it does not interfere with the adjustment of treatment position during radiotherapy. It is suitable for different finger shapes of children, adults and other groups.

[0044] 2. Optical Sensing Monitoring Module: Employing advanced optical sensing technology, this module integrates a red light emitting component, an infrared light emitting component, a photoelectric detection component, and a signal conditioning chip. By allowing red and infrared light to penetrate the patient's fingertip tissue, and utilizing the difference in absorption of different wavelengths of light by oxyhemoglobin and deoxyhemoglobin in the blood, the photoelectric detection component collects the transmitted light signal. After filtering, amplification, and analog-to-digital conversion by the signal conditioning chip, precise blood oxygen saturation and heart rate data are obtained; enabling non-invasive, continuous monitoring and zero-interference throughout the radiotherapy process.

[0045] 3. One-button emergency call module: Integrates an anti-accidental touch button and a vibration feedback component. The button uses a silicone raised structure with an anti-slip texture on the surface. The trigger pressure threshold can be set to avoid accidental touch or accidental triggering during treatment. After the patient triggers the button, the built-in vibration motor immediately starts, sending a successful trigger signal to the patient. At the same time, the module quickly sends a distress signal to the anti-interference transmission unit.

[0046] 4. Low-power power supply module: It adopts a rechargeable lithium polymer battery and is equipped with a magnetic charging interface for convenient and fast charging by medical staff; it has a built-in low-power management chip that can automatically switch between working and sleep modes according to the monitoring cycle to meet the needs of multi-patient treatment monitoring throughout the day.

[0047] The anti-interference transmission unit includes:

[0048] This unit is a core component that overcomes the limitations of electromagnetic shielding in radiotherapy rooms. It employs optical anti-interference transmission technology to achieve real-time and stable transmission of physiological data and emergency signals.

[0049] 1. Transmitting component: Installed inside the shielding wall near the protective door in the equipment room, it is connected to the patient's wearable monitoring unit via a wire (the wire is embedded in the protective sleeve). After receiving monitoring data and distress signals, it converts the electrical signals into optical signals of a specific wavelength. The transmitting component is equipped with an optical focusing lens to ensure directional signal transmission.

[0050] 2. Receiving component: It is installed on the outside of the shielding wall on the side of the operating room and aligned with the transmitting component through a preset optical channel; the channel is equipped with a lead alloy anti-radiation shielding sleeve, which only allows the optical signal to be transmitted along the preset path, ensuring that the signal can penetrate the electromagnetic shielding layer and preventing radiation leakage in the machine room; the receiving component integrates an optical receiving lens and a signal conversion chip to convert the optical signal back into an electrical signal and transmit it to the therapist's terminal unit.

[0051] The therapist terminal unit includes:

[0052] 1. Data parsing module: It adopts a high-performance microcontroller to quickly parse the received blood oxygen saturation, heart rate data and distress signals, convert the raw data into intuitive values ​​and dynamic curves, and compare them in real time with the built-in normal thresholds (blood oxygen saturation ≥95%, heart rate 60-100 beats / min) to determine whether there are any abnormal physiological data.

[0053] 2. Large screen display module: adopts a touch screen, which displays core information in different areas: the left area displays basic information such as patient name and treatment plan in real time; the middle area displays blood oxygen saturation value and dynamic curve, heart rate value and dynamic curve, and the curve can be zoomed in to view details; the right area displays the device working status (monitoring / standby), communication status (normal / interrupted) and alarm information; it supports switching to view historical data curves (last 24 hours).

[0054] 3. Audible and Visual Alarm Module: Integrates a dual-color LED alarm light and an adjustable frequency buzzer. When an emergency call from a patient is received, a Level 2 strong alarm is triggered: the LED light emits a solid red light, and the buzzer emits a high-frequency warning sound of 80-100dB. When abnormal physiological data is detected, a Level 1 alarm is triggered: the LED light emits a flashing yellow light, and the buzzer emits a low-volume warning sound of 60-80dB. The two alarm modes can quickly distinguish priorities, facilitating timely responses from therapists.

[0055] 4. Data storage module: It adopts a high-capacity storage chip to automatically and in real time store the patient's physiological data, alarm trigger time, alarm type (emergency call / physiological abnormality), therapist treatment records and other information; the data retention period is ≥90 days, and it supports USB export and docking with the hospital information system (HIS) to realize the synchronous storage and traceability of data and patient treatment records, providing a basis for case analysis and treatment evaluation.

[0056] The working principle includes:

[0057] 1. System Deployment and Startup: Before treatment, medical staff select a flexible fingertip wear body of appropriate size according to the patient's condition, put it on the patient and adjust it to a comfortable state, ensuring that the optical sensor probe fits tightly against the fingertip skin; after the system is started, the patient wearable monitoring unit, anti-interference transmission unit and therapist terminal unit automatically complete initialization, establish a stable communication connection, and the large screen display module enters the monitoring standby state.

[0058] 2. Vital Signs Monitoring and Data Transmission: During radiotherapy, the optical sensor monitoring module non-invasively and continuously collects the patient's fingertip blood oxygen saturation and heart rate data. After preprocessing, the data is transmitted to the transmitting component of the anti-interference transmission unit. The transmitting component converts the data into optical signals, which are transmitted to the receiving component through a preset optical channel and through the shielding layer. The receiving component restores the electrical signals and transmits them to the therapist's terminal unit. After processing by the data parsing module, the real-time values ​​and dynamic curves are displayed on the large screen display module, and the data storage module automatically stores them synchronously.

[0059] 3. Abnormal Warning and Emergency Response: When the monitored data exceeds the built-in normal threshold, the therapist terminal unit triggers a Level 1 warning (flashing yellow light + low-volume alert sound), and the large screen automatically highlights the abnormal data curve to remind the therapist to pay attention. When the patient feels unwell or experiences an emergency, triggering the one-button emergency call button, the system immediately sends a distress signal to the therapist terminal unit, triggering a Level 2 strong warning (solid red light + high-frequency warning sound). The terminal unit accurately records the trigger time, the physiological data at that time, and the patient's information. After receiving the warning, the therapist can quickly grasp the patient's status through the large screen and promptly go to the treatment room for handling. The treatment process and results are simultaneously recorded to the data storage module.

[0060] 4. Post-treatment data processing: After the treatment is completed, the system automatically generates a vital sign monitoring report for the patient during this treatment, including the entire data curve and records of abnormal events (if any); the data can be exported or synchronized to the HIS system for subsequent analysis by medical staff.

[0062] This embodiment provides a patient vital signs monitoring and emergency call system for radiotherapy rooms, including:

[0063] System component selection and assembly:

During assembly, a medical anti-allergy film is attached to the inner side of the body to improve wearing comfort.

[0067] 2) Assembly of optical sensing monitoring module: An optical sensing chip is selected as the core component, integrating a red light emitting tube and a silicon photodetector tube; the module is fixed to the left monitoring area of ​​the flexible fingertip wearing body to ensure that the sensing probe corresponds to and fits the fingertip skin, and the probe surface is covered with transparent medical protective glass; the module is connected to the internal low-power microcontroller through wires, and the wires are embedded in the silicone protective sleeve inside the body to avoid wire wear.

[0068] 3) One-button emergency call module assembly: The anti-accidental touch button adopts a silicone raised structure with an anti-slip diamond texture pressed on the surface. A pull-down resistor is installed below the button, and the trigger pressure threshold is set by adjusting the button spring force. The button is fixed to the right control area of ​​the wearer and connected in parallel with the internal flat vibration motor. The trigger signal is transmitted to the microcontroller through the I2C interface.

[0069] 4) Low-power power supply module assembly: Lithium polymer battery is selected and equipped with a Type-C magnetic charging interface. The charging interface is fixed to the edge of the right control area of ​​the wearer. The battery and low-power management chip are soldered and assembled. The chip is connected to the microcontroller through the GPIO interface to realize the power control function of automatic sleep during monitoring interval and automatic wake-up during monitoring. After assembly, the battery and chip are encapsulated in a sealed cavity inside the wearer to ensure radiation protection and interference prevention.

[0070] Anti-interference transmission unit assembly:

[0071] a) Emitting component assembly: The outer shell of the transmitting component is made of lead alloy material and is internally integrated with a red light emitting tube and a focusing lens. The emitting tube is welded to the drive circuit. The drive circuit is connected to the microcontroller of the patient-worn monitoring unit through a wire. The wire is embedded in a metal protective sleeve, which is fixed in a wire groove inside the shielding wall of the radiotherapy room. The transmitting component is fixed inside the shielding wall near the protective door in the room, ensuring that the focusing lens of the transmitting end faces the direction of the operating room.

[0072] b) Receiver assembly: The receiver assembly shell is also made of lead alloy material, and the silicon photodiode and receiving lens are integrated inside. The photodiode and signal conversion chip are soldered together. An 8mm diameter through hole is opened in the lead shielding wall (30cm thick) of the radiotherapy room as an optical channel. A 4mm thick lead alloy shielding sleeve is nested in the channel. Flexible lead rubber seals are installed at the connection between the sleeve and the shielding wall to prevent radiation leakage. The receiver assembly is fixed on the outside of the shielding wall on the side of the operating room and precisely aligned with the transmitter assembly through the optical channel. The alignment error is controlled within ±2mm to ensure stable transmission of optical signals.

[0073] Therapist terminal unit assembly:

[0074] a) Data parsing module assembly: A high-performance microcontroller is selected as the core. The microcontroller is connected to the receiving component of the anti-interference transmission unit through the UART interface to receive the restored physiological data and distress signals.

The data parsing and anomaly judgment functions are realized through programming.

[0075] b) Large screen display module assembly: A touch screen is selected and connected to the microcontroller via an HDMI interface; the large screen's regional display program is implemented using Qt programming. The left area is bound to the patient's basic information database, the middle area uses Chart.js to draw dynamic curves of blood oxygen saturation and heart rate, supports the review and zoom-in viewing of historical data for the past 24 hours, and the right area displays the device status, communication status, and alarm information in real time.

The alarm logic is set by programming: when an emergency call signal is received, a solid red light and an 80-100dB high-frequency warning sound are triggered; when an abnormal physiological data signal is received, a flashing yellow light (flashing frequency 2Hz) and a 60-80dB low-volume prompt sound are triggered.

[0077] d) Data storage module assembly: A high-capacity SD card is selected as the storage medium and connected to the microcontroller via an SPI interface; the data storage program is set to real-time storage mode with a sampling frequency of 10Hz. The stored content includes patient ID, treatment time, real-time blood oxygen saturation data, heart rate data, alarm trigger time, alarm type, and therapist treatment records; the SD card supports hot-swapping and is also connected to the hospital HIS system via an Ethernet interface to achieve synchronous data storage and traceability.

[0078] The system debugging and operation process includes:

[0079] System debugging:

[0080] a) Communication debugging: Start the patient-worn monitoring unit and the therapist terminal unit, establish a communication connection through the anti-interference transmission unit, and test the stability of optical signal transmission: Under the normal working environment of the radiotherapy room, continuously transmit physiological simulation data for 1 hour, record the transmission delay and interruption, and ensure that the transmission delay is ≤300ms and the data accuracy is ≥99.5%; if the transmission is interrupted, adjust the alignment angle of the transmitting component and the receiving component until the communication is stable.

[0081] b) Monitoring accuracy adjustment: Select healthy volunteers to wear the monitoring unit and conduct comparative tests using a standard medical monitor. Adjust the signal amplification factor and filtering parameters of the optical sensing module to ensure that the blood oxygen saturation monitoring error is ≤±2% and the heart rate monitoring error is ≤±1 beat / min, so as to ensure that the monitoring accuracy meets clinical requirements.

[0082] c) Alarm function debugging: Test the first-level warning function by simulating blood oxygen saturation and heart rate data that exceed the threshold; test the second-level warning function by manually triggering the one-button emergency call button, and ensure that the light and sound signals of the two warning modes are clearly distinguishable and the alarm records are accurate and complete.

[0083] Actual operation process:

[0084] 1) Pre-treatment preparation: Medical staff adjust the length of the flexible fingertip wearing body according to the patient's age (children aged 3-15 or adults), put the monitoring unit on the patient, and ensure that the optical sensor probe fits tightly to the fingertip skin without pressure; enter the patient's basic information (name, gender, age, treatment plan) through the therapist terminal unit, start the system, complete the initialization and communication connection of each unit, and confirm that the large screen displays the "monitoring standby" status.

[0085] 2) Radiotherapy process monitoring: After the patient enters the radiotherapy room and is fixed in the treatment position, the therapist starts the radiotherapy equipment and monitoring system. The optical sensor monitoring module non-invasively and continuously collects the patient's fingertip blood oxygen saturation and heart rate data, which are transmitted to the therapist's terminal unit in real time through the anti-interference transmission unit. The large screen displays the real-time data dynamic curve in different areas. The therapist can monitor the patient's status in real time through the large screen, and the data storage module automatically stores the data throughout the process.

[0086] 3) Abnormal Response and Handling: If the monitored data exceeds the normal threshold, the system will immediately trigger a Level 1 warning (flashing yellow light + low volume alert sound), and the abnormal data curve will be automatically highlighted on the large screen. The therapist can view the detailed data on the large screen and, if necessary, inquire about the patient's status via voice intercom (external voice module). If the patient triggers the one-button emergency call button, the system will trigger a Level 2 strong warning (solid red light + high-frequency warning sound). The terminal unit will accurately record the trigger time, patient information, and physiological data at that time. The therapist will immediately suspend radiotherapy and go to the machine room for treatment. The treatment process and results will be entered into the system simultaneously.

[0087] 4) Post-treatment follow-up: After radiotherapy, medical staff remove the monitoring unit worn by the patient and shut down the system; export the vital signs monitoring report of this treatment through the therapist's terminal unit, including the full data curve and abnormal event records (if any), and upload the report to the hospital's HIS system and store it in association with the patient's treatment record; disinfect the monitoring unit to prepare for the next use.

[0088] Special scenario adaptation instructions:

[0089] a) Scenario for children under general anesthesia: For children with impaired consciousness after general anesthesia, the smallest flexible fingertip wearer should be selected and secured with the assistance of parents to prevent children from unconsciously breaking free; the sleep function of the monitoring unit should be turned off to ensure continuous monitoring throughout the process; the therapist can monitor the monitoring data in real time through a large screen, and if a sudden drop in blood oxygen (≤90%) occurs, the emergency treatment procedure should be triggered immediately.

[0090] b) Ultra-thick shielded wall computer room scenario: Add a low-frequency wireless transmission component to the anti-interference transmission unit to form a dual-mode transmission mode with optical transmission. When the optical transmission signal attenuates, it automatically switches to low-frequency wireless transmission to ensure stable data transmission. At the same time, thicken the lead alloy shielding sleeve of the optical channel to enhance the radiation leakage prevention effect.

[0091] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
