Description

Technical Field

[0001] The present invention relates to the field of ICU nursing, and in particular to an ICU real-time monitoring intelligent nursing system. Background Art

[0002] In the current ICU nursing field, traditional monitoring methods mainly rely on manual regular inspections and observations, which not only consumes a lot of manpower, but also has the risk of untimely and inaccurate monitoring. Traditional beds have a single function and are difficult to meet the complex and changing nursing needs. The safeguards for patients' infusion management, position adjustment, and fall prevention are relatively weak. At the same time, the information between different devices is isolated and cannot be fully integrated intelligently. After obtaining the information, it is impossible to carry out follow-up processing in time. Medical staff need to rush to the scene to handle it, which is inefficient and difficult to fully guarantee the safety and quality of care of patients.

[0003] After searching, the Chinese invention patent application publication number CN111145894B discloses a medical monitoring and interactive system, including a pressure acquisition device, a data entry module, a pressure analysis module, a timer, a data transmission module, an information interconnection module, a video monitoring module, a controller, an image analysis module, and an information processing module. The pressure acquisition device is a plurality of pressure sensors installed under the bed board, and the pressure sensors can collect the pressure information of each area of ​​the patient lying on the bed in real time; the present invention collects the number of times and the size of the pressing pressure of the patient on the bed board in real time through a plurality of pressure acquisition devices, and then inputs the weight ratio through the data entry module; receives the weight ratio transmitted by the data entry module through the data transmission module; inputs the weight ratio to the pressure analysis module through the data transmission module to calculate the patient's rest state value; after receiving the warning signal, the information interconnection module sends it to the mobile phones of doctors and family members for display. The existing patent application has the problem that the pressure analysis results are not combined with other protective measures.

[0004] How to achieve comprehensive real-time monitoring and intelligent care in the ICU has become a technical problem that needs to be solved. Summary of the invention

[0005] The purpose of the present invention is to provide an ICU real-time monitoring intelligent nursing system in order to overcome the defects of the above-mentioned prior art.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] According to one aspect of the present invention, an ICU real-time monitoring intelligent nursing system is provided, the system comprising a main control module, and a real-time position monitoring module, an infusion auxiliary module, a bedside auxiliary module and a multi-level alarm module respectively connected to the main control module, and data information is shared between the modules;

[0008] The real-time body position monitoring module includes a plurality of thin film pressure sensors, which divide the ICU bed into a large head and trunk area A, a large buttocks area B, a large leg area C and a large calf area D, each large area is divided into a plurality of small areas, each small area is divided into a plurality of cells, and each cell is provided with the thin film pressure sensor to measure pressure;

[0009] The main control module determines the patient's body position based on the pressure distribution of different parts of the patient's body measured by the thin film pressure sensor, and automatically judges the data reported by the real-time body position monitoring module, the infusion auxiliary module and the bed edge auxiliary module, and gives relevant nursing instructions.

[0010] Preferably, if the number of cells in a small area in the large area that receive pressure signals exceeds the set point, it is determined that the small area has effective force;

[0011] When a large area includes at least one small area with effective force, the large area is determined to have effective force. Preferably, if at least one small area in each large area has effective force, the main control module of the system determines that the patient is in a supine position;

[0012] If at least one large area has effective force, and the effective force area is not at the edge, the main control module of the system determines that the patient is in a non-lying posture;

[0013] When one of the following two conditions is met, the patient is judged to be in a dangerous position, the bedside auxiliary module is automatically started, and a Class II alarm is released:

[0014] 1) In the lying position, at least two small areas in all large areas have effective force at the edge;

[0015] 2) In non-lying posture, at least one small area in all large areas has effective force at the edge.

[0016] Preferably, the real-time body position monitoring module also includes a custom pressure. When a fixed medical machine or instrument is placed on a fixed position on the bed, a specific pressure permission is set in an area with cells as pixels.

[0017] More preferably, when the pressure in the custom pressure area does not exceed the allowable pressure value range, no alarm is triggered; otherwise, it indicates that the object moves abnormally and triggers a Class II alarm; if the pressure value disappears, a Class III alarm is triggered;

[0018] The bed edge assist module is automatically activated when it is detected that the allowed pressure value of the custom pressure zone moves to a small area in the corner of the bed.

[0019] Preferably, the bedside auxiliary module comprises an infrared sensor installed on the bedside, an electromagnetic lock installed on the bedside, a bedside guardrail, a motor, a gear and a magnetic suction device;

[0020] The motor drives the gear to rotate, causing the connecting rod to move in a circle with the bed guardrail until the upper and lower magnetic devices are adsorbed. The magnetic sensor sends an adsorption signal to the main control module of the system, and the main control module issues a command to stop the motor.

[0021] More preferably, the magnetic attraction device includes a moving contact 86 of a magnetic attraction locking device on the bed edge, a static contact 871 of a magnetic attraction locking device on the bed edge, and a static contact 872 of a magnetic attraction locking device under the bed edge.

[0022] More preferably, if the main control module issues a bed edge guardrail rising instruction, the bed edge auxiliary module first determines whether the bed edge guardrail is in the upper position or the lower position through the magnetic suction sensor, and then determines whether it is locked through the magnetic suction sensor;

[0023] If the magnetic sensor does not send an adsorption signal and the motor is running, the bed edge guardrail (88) is in the process of rising or falling; if the magnetic sensor does not send an adsorption signal and the motor is not running, the system will prompt that a fault has occurred in the area.

[0024] Preferably, the infusion auxiliary module includes a photoelectric liquid level sensor and a relay pipe clamp. The photoelectric liquid level sensor and the relay pipe clamp are installed on the infusion pipe in sequence from the side close to the infusion bottle. When the photoelectric liquid level sensor detects the end of infusion, the relay pipe clamp can quickly clamp the infusion pipe and transmit the clamping status to the main control module in real time.

[0025] Preferably, the system supports multiple care modes:

[0026] Level 1 nursing mode: The infrared sensor alarms and the system suspends monitoring. In this mode, the nursing staff and the doctor diagnose and treat the patient along the bed;

[0027] Secondary nursing mode: the infrared sensor alarms and the system suspends monitoring, the bedside guardrails are fully or partially opened, and the nursing staff and doctors operate on the patient;

[0028] Level 3 nursing mode: all modules are closed, the patient leaves the bed or undergoes rescue operation;

[0029] Complete nursing monitoring mode: all sensors are turned on to collect data for auxiliary intelligent nursing;

[0030] And custom care monitoring mode: customize the status of each sensor according to special needs.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1) The ICU real-time monitoring intelligent nursing system of the present invention integrates the interactive real-time posture monitoring module, infusion auxiliary module, bedside auxiliary module and multi-level alarm module, which can effectively improve the nursing efficiency and quality, provide patients with a safer and more reliable nursing environment, and greatly reduce the workload and reaction time of medical staff through the automatic processing function of the system, and provide a variety of processing references and prompts so that medical staff can perform nursing operations more timely and effectively.

[0033] 2) The real-time body position monitoring module of the present invention divides the hospital bed into multi-level large areas, small areas and cells, and judges the patient's posture according to the pressure distribution. When it senses that the patient is in a dangerous area, it automatically starts the bed edge auxiliary module and triggers an alarm, providing the patient with a safe, reliable and intelligent nursing environment.

[0034] 3) The real-time body position monitoring module of the present invention reduces system misjudgment caused by nursing staff placing some medical equipment and other objects on the bed during nursing by customizing the pressure area, thereby increasing the reliability and stability of intelligent nursing.

[0035] 4) The real-time body position monitoring module, infusion auxiliary module, bedside auxiliary module and multi-level alarm module of the present invention share data. The main control module can automatically trigger another module to perform nursing according to the data judgment result of one of the modules. For example, when the infusion auxiliary module detects that the infusion is about to end, it transmits the pipe clamping state to the main control module in real time, and triggers the alarm module to issue a Class II alarm, thereby improving the intelligence of ICU nursing and improving nursing efficiency and safety.

DETAILED DESCRIPTION

[0044] 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 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 should fall within the scope of protection of the present invention.

[0045] The present embodiment relates to an ICU real-time monitoring intelligent nursing system, which can effectively improve nursing efficiency and quality, provide patients with a safer and more reliable nursing environment, and greatly reduce the workload and response time of medical staff through the automatic processing function of the system, and provide a variety of processing references and prompts so that medical staff can perform nursing operations more promptly and effectively.

[0046] like Figure 1 and Figure 2 The system includes a main control module, and an infusion auxiliary module, a real-time body position monitoring module, a bedside auxiliary module and an alarm module respectively connected to the main control module. The modules share data information. The main control module determines the data parameters of each module and gives operating instructions to the corresponding module to provide real-time medical care faster and more effectively.

[0047] The main control module includes a high-performance PLC 6. As the core control center, the main control module adopts advanced microprocessor technology and high-speed data processing capabilities. It can quickly and accurately receive signals from sensors in each module and perform precise control in strict accordance with the preset program logic. It has strong anti-interference ability and stability to ensure reliable operation in complex medical environments.

[0048] The infusion auxiliary module includes a photoelectric liquid level sensor 1 and a relay pipe clamp 2.

[0049] Photoelectric liquid level sensor 1: Installed on the infusion pipeline, it uses advanced optical detection technology to detect small changes in the infusion level in real time and accurately. The sensor has high sensitivity and fast response characteristics, and can detect the state of infusion about to end or has ended in an instant, and send a signal to the system in time.

[0050] Relay pipe clamp 2: Located below the photoelectric liquid level sensor 1 (away from the infusion bottle), it integrates advanced relay control technology and high-precision mechanical clamping devices. When the photoelectric liquid level sensor 1 detects the end of infusion, the relay pipe clamp 2 can quickly and accurately clamp the infusion pipe to prevent the patient's blood from flowing back. At the same time, the relay pipe clamp 2 has a state feedback function, which can transmit the clamping state to the PLC 6 in real time to ensure that the system accurately grasps the status of the infusion pipe.

[0051] like Figure 3 to Figure 5 The real-time body position monitoring module includes film pressure sensors 4 set in multiple areas of the bed. The film pressure sensors 4 are distributed in different areas of the multifunctional bed, including the head and trunk large area A, the buttocks large area B, the leg large area C, and the calf large area D. The large area is divided into a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, and p, a total of 16 small areas, such as Figure 4 Each small area is divided into 16 cells, such as Figure 5 The thin-film pressure sensor adopts advanced pressure-sensitive technology, which can accurately measure the pressure distribution of different parts of the patient's body. It has high resolution and fast response characteristics, can monitor the patient's body position changes and pressure conditions in real time, can accurately and reliably measure the parameters of each cell, and transmit the measurement data to the main control module, compare the database and give nursing instructions.

[0052] The main control module also includes a touch display control screen and a program processing unit 5. Each large area is further divided into multiple small areas, and multiple small areas are further divided into final cells. Each cell receives a pressure signal and transmits it to the touch display control screen and the program processing unit 5 in real time. The touch display control screen and the program processing unit 5 determine the patient's position or whether it is working normally according to the small area, large area, or single cell where the cell is located. The weight is calculated according to the gravity applied to each cell of the film pressure sensor, and the operator confirms and enters the database. The database will use a value of ±10% as the normal range.

[0053] For example, in a normal lying posture, if the cells in a small area of ​​large area A, large area B, large area C, or large area D receive pressure signals exceeding the set number of points (set to 4 points in this implementation), then the small area is determined to be effectively stressed. If one or more small areas in large area A, large area B, large area C, and large area D are effectively stressed, then it is determined to be a lying posture. If the stressed area is not at the edge, such as Figure 4 Among a, b, i, j, or g, h, o, p, the system determines that the lying position is normal and sends a command to the display screen to display the lying position Class I safety.

[0054] If the position is not lying flat (i.e. sitting or other positions), the cells in a small area of ​​large area A, large area B, large area C, and large area D receive pressure signals exceeding the set number of points (set to 4 points in this implementation), then it is determined that the small area is effectively stressed. Among large area A, large area B, large area C, and large area D, one large area, two large areas, or three large areas have effective stress. If the effective stress area is not at the edge, such as Figure 4 In a, b, i, j, or g, h, o, p, the system determines the normal sitting posture or other posture and sends a command to the display screen to display the sitting posture or other posture Class I safety. When a large area contains at least one small effective force area, the large area is determined to have effective force.

[0055] If the cells in a small area of ​​the dangerous location, large area A, large area B, large area C and large area D exceed the set number of points (set to 4 points in this implementation) and receive pressure signals, then it is determined that the small area is effectively subjected to force.

[0056] When one of the following two conditions is met, the patient is judged to be in a dangerous position, the bedside auxiliary module will be activated, and a Class II alarm will be released:

[0057] 1) In the lying position, there are more than or equal to 2 small areas in the large area A, large area B, large area C and large area D with effective force at the edge;

[0058] 2) In a non-lying posture, at least one small area among large area A, large area B, large area C and large area D has effective force at the edge;

[0059] The small area at the edge is Figure 4 a, b, i, j, or g, h, o, p.

[0060] Customized pressure judgment: Customize the pressure judgment of a certain area. When a fixed medical machine or instrument is placed on a fixed part of the bed, the screen settings can be used to set specific pressure permissions in the area with cells as pixels. If cells a1 to a16 are set to allow pressure to exist, there will be fuzzy pressure judgments in the area of ​​cells a1 to a16. Place a specific pressure source within the designated range. This area will record the pressure value within the current judgment range. The allowable range is ±10% of the recorded pressure value. When the pressure value changes beyond this range, it will prompt abnormal movement of the object and release a Class II alarm. If the pressure value disappears, it will be a Class III alarm. When the pressure value is allowed to be in a dangerous position, the bed edge auxiliary module will still be activated unless the bed edge auxiliary module is manually released.

[0061] As mentioned above, if the pressure does not match the normal value, or does not match the normal sensor distribution position data in the database, the system will give a Class II yellow warning or a Class III red alarm based on the sensor distribution and the sudden drop or increase in pressure and the sudden loss of signal. Cells are used to determine whether a small area is under heavy pressure. When enough cells are covered by pressure, it will be determined that the small area is covered by pressure. This is to prevent the system from misjudging when the nursing staff places some medical equipment such as tape, sphygmomanometers, etc. on the bed during nursing.

[0062] The touch display control screen and program processing unit 5 provide a human-computer interaction platform, equipped with a high-resolution display screen and sensitive touch response technology, providing medical staff with an intuitive, clear and convenient human-computer interaction interface. The interface design is simple and clear, and can display detailed information of patients in each bed in real time, including infusion status, body position distribution, pressure value, and anti-fall alarm. At the same time, it supports multi-window operation and fast switching, which is convenient for medical staff to monitor the conditions of multiple patients at the same time. It contains a CPU processor and a self-written database for judging real-time data and giving instructions.

[0063] The bedside auxiliary module includes an infrared sensor 3 installed on the bedside. The infrared sensor 3 uses advanced infrared detection technology and can accurately detect whether there is an object cutting the infrared rays. The infrared sensor 3 has high sensitivity and fast response characteristics, and can detect the risk of a patient falling instantly and send a signal to the system in time.

[0064] The bedside auxiliary module also includes an electromagnetic lock 8, which is installed on the four bedsides of the multifunctional bed and is precisely controlled by PLC 6. The electromagnetic lock 8 is made of high-strength materials and advanced electromagnetic control technology, and has high safety and reliability. Without the consent of medical staff, the electromagnetic lock cannot be unlocked by external force, effectively preventing the patient from falling due to misoperation. Preferably, the electromagnetic lock 8 is a magnetic bedside lock.

[0065] The system also includes a UPS uninterruptible power supply 7, which is connected to the touch display control screen and the program processing unit 5. When the patient is unable to get up and needs to be transferred to another department or go to another place for treatment, such as CT, MRI, etc., a temporary power supply is provided to support the normal operation of the system.

[0066] UPS uninterruptible power supply 7 provides backup power in the event of external power outage, allowing the entire system to work normally for 4 hours to cope with emergencies.

[0067] The system also includes an alarm module and a data management module connected to the main control module.

[0068] A large number of infusion parameters and human body position parameters are programmed in the main control module of the system. The main control module gives different prompts to medical staff according to different parameters, and gives instructions to the infusion auxiliary module, real-time body position monitoring module, alarm module and bedside auxiliary module. The alarm levels are divided into three categories. Class I prompts are green normal indicator lights and the buzzer is silent. Class II alarms are yellow abnormal indicator lights and the buzzer sounds intermittently. Class III alarms are red emergency indicator lights and the buzzer sounds continuously.

[0069] Type I prompt: All parameters in the comparison database are in normal state. No prompt sound is required, and the indicator light is green.

[0070] Class II alarm: All parameters in the comparison database are in an abnormal state, and the sensor receives warning data. Intermittent prompt sound, yellow indicator light, including the following abnormal conditions:

[0071] For example: When the photoelectric liquid level sensor finds that there is no liquid, it will issue a yellow alarm indicator light and send a command to the catheter clamp to clamp the catheter.

[0072] For example, if the gravity sensor finds that the patient is approaching the edge of the bed, it will issue a yellow alarm indicator and send a command to the bedside auxiliary module. The bedside auxiliary module will determine the current status and give a command for automatic operation.

[0073] For example: the main power supply is suddenly switched to UPS power supply, and the UPS power supply is normal.

[0074] For example: the infrared sensor detects that there is an object at the edge of the bed.

[0075] Class III alarm: Class II alarm is not manually confirmed within 5 minutes, or is manually confirmed but the parameters do not return to normal values ​​within 5 minutes after confirmation. The sensor value is directly at the alarm value. A long beep sound is heard and the indicator light turns red.

[0076] If a control unit fails to perform an operation during the execution of Class II, such as the catheter clamp does not move, the bed edge baffle is stuck by an object, etc., causing the system to detect that the component has not arrived at the designated position on time as instructed, the system will issue a red alarm indicator and prompt the medical staff to handle the event immediately on the display screen.

[0077] For example: the gravity sensor suddenly drops, suddenly increases, or suddenly disappears altogether.

[0078] Such as: UPS power supply exceeds 30 minutes.

[0079] For example, when the bed edge auxiliary module is working, the infrared sensor detects an object.

[0080] Infusion real-time monitoring module: When the liquid level in the infusion tube drops to the photoelectric liquid level sensor 1, the liquid level sensor 1 will send a signal to the relay catheter clamp 2, tighten the catheter within 5 seconds and issue a Class II warning to the auxiliary care system. If the catheter clamp does not work or does not work properly after 5 seconds, a Class III alarm will be issued.

[0081] like Figure 6 and Figure 7 , Bed edge auxiliary module: The motor 84 drives the gear 85 to rotate forward or reverse, so that the connecting rod and the bed edge guardrail 88 make a circular motion until the upper and lower magnetic devices are adsorbed. When the magnetic devices are adsorbed, the magnetic sensors (the upper end sensor 83 of the bed edge and the lower end sensor 89 of the bed edge) send an adsorption signal to the main control module of the system, and the main control module will issue a command to stop the motor. The upper and lower magnetic devices include the upper magnetic locking device moving contact 86 of the bed edge, the upper magnetic locking device static contact 871 of the bed edge, and the lower magnetic locking device static contact 872 of the bed edge.

[0082] For example, when the main control module issues a rising command, the bed edge auxiliary module will first determine whether the bed edge guardrail 88 is in the upper position or the lower position through the magnetic suction sensor (the upper end sensor 83 of the bed edge and the lower end sensor 89 of the bed edge), and then determine whether it is locked through the magnetic suction sensor (the upper end sensor 83 of the bed edge and the lower end sensor 89 of the bed edge). If neither of the two magnetic suction sensors sends an adsorption signal and the motor is running, it means that the bed edge guardrail 88 is rising or falling. If the magnetic suction sensor does not send an adsorption signal and the motor is not running, the system will prompt that there is a fault in this area.

[0083] If it is in the upper locked state, no operation will be performed and the display will prompt that the guardrail has been raised and locked.

[0084] If the upper end is not locked, the display will prompt that the guardrail is raised and not locked.

[0085] If the lower end is unlocked, the screen will prompt that the guardrail is lowered and unlocked. At this time, the guardrail will be raised, and the screen will show that the bed edge guardrail is rising and unlocked. When the guardrail is raised to the upper end, the magnetic lock is locked, and the screen will show that the guardrail has been raised and locked.

[0086] If the guardrail is locked at the lower end, the screen will prompt that the guardrail is lowered and locked. At this time, the magnetic lock will be unlocked, and the screen will prompt that the guardrail is lowered and not locked. Then the guardrail will be raised, and the screen will show that the bed edge guardrail is rising and not locked. Until the guardrail is raised to the upper end, the magnetic lock is locked, and the screen will show that the guardrail has been raised and locked.

[0087] During any bed edge movement, a Class II alarm will be issued. If an object blocks or cuts the infrared sensor, the guardrail movement will be stopped and a Class III alarm will be issued.

[0088] To facilitate emergency treatment, all the above systems can be manually disabled and enabled individually. When the intelligent care system is restarted, all modules are enabled by default.

[0089] The system provides multiple mode switching, which makes it convenient for medical staff to quickly use the corresponding mode and improve work efficiency.

[0090] Level 1 nursing mode: Infrared sensor 3 alarms temporarily stop monitoring, allowing nursing staff and doctors to diagnose and treat patients along the bed.

[0091] Secondary nursing mode: the infrared sensor 3 alarms and temporarily stops monitoring, and the electromagnetic lock 8 is fully or partially opened, providing nursing staff and doctors with the opportunity to operate on the patient.

[0092] Level 3 nursing mode: All modules are closed, providing patient discharge or rescue operations.

[0093] Full Care Monitoring Mode: All sensors are turned on, providing all data logging and protection.

[0094] Customized nursing monitoring mode: Customize the start or shut down of each sensor according to special needs and save the current mode.

[0095] Take the full nursing detection mode, when the system is fully turned on, as an example: when the system turns on all monitoring, the working status of all sensors will be monitored and displayed in real time on the screen. When a sensor receives an abnormal signal, a corresponding prompt screen will be given on the touch screen, the alarm will emit a corresponding prompt sound, and the alarm light will light up in a corresponding color. Until the nursing staff actively resets or turns off this function. When resetting this function, if the data received by the sensor is not restored to normal within the specified time, it will be judged as an invalid operation, and the alarm level will be raised to the highest level. When this function is turned off, it is regarded as giving up this detection, and the corresponding sensor and its data processing process will be disabled.

[0096] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
