Description

Technical Field

[0001] The present invention relates to the technical field of monitoring beds, and in particular to an intelligent monitoring bed and a monitoring system. Background Art

[0002] Intelligent bed monitoring is a medical device that integrates advanced technology. It improves nursing efficiency and patient safety by real-time monitoring of patients' physiological parameters (such as heart rate, respiratory rate and body temperature), automatic alarm and data analysis. It can transmit data remotely, support medical staff to check the patient's status at any time, reduce on-site inspections, and improve the quality of care.

[0003] In current orthopedic care, the railings of hospital beds are often equipped with manual lifting buttons, so that medical staff can prevent patients from getting out of bed by raising the railings.

[0004] However, in actual use, orthopedic patients have special conditions and are unable to move around easily, and they need to follow doctor's orders to recuperate. However, some patients do not follow doctor's orders and get out of bed without permission, which can easily lead to accidents such as falls. Currently, there is no monitoring system between the bed and the nursing station. When a patient gets out of bed without permission, medical staff cannot monitor it in time, which may cause the patient to suffer secondary injuries. In addition, there are fewer nurses on duty at night and they make regular rounds. When a patient calls the front desk, the nurse may not be able to handle it in the first time, which delays the response to the patient's emergency, affects the patient's recovery process, and may bring serious safety hazards. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides an intelligent monitoring bed and a monitoring system, which solves the problem in the prior art that when medical staff cannot observe every ward at all times, patients can get out of bed and move around at will, thus causing safety risks.

[0011] A monitoring system for an intelligent monitoring bed includes the following modules:

[0012] The data sensing module is connected to each group of sensor devices inside the intelligent monitoring bed, and receives and translates the data signals transmitted from each group of sensors;

[0013] The sensor data analysis module receives the data from the data sensor module, analyzes and processes the data, and uses algorithms and models to determine the patient status reflected by the data;

[0014] The abnormal alarm module triggers the alarm function according to the patient status determined by the sensor data analysis module, including when the patient leaves the bed;

[0015] Intelligent remote monitoring module allows medical staff to monitor the patient's condition remotely and in real time through the network, and transmit the data of each bed to the hospital's monitoring center, the digital display screen of the nurse station and the mobile devices of medical staff;

[0016] The data analysis module records the time of each triggering of the guardrail, pressure sensor, and infrared sensor, as well as the patient's bed number, and conducts a comprehensive analysis of the data collected over a period of time to generate a patient status report, including the patient's activity patterns and frequency of leaving bed.

[0017] Preferably, the data sensing module includes multiple groups of sensors, including pressure sensors and infrared sensors, for real-time monitoring of the patient's physiological parameters and behavioral activities, wherein the pressure sensor is used to detect whether the patient has left the bed, and the infrared sensor is located inside the safety gratings on both sides in a counter-radiation manner.

[0018] Preferably, the sensor data analysis module includes a central processing unit, and integrates data from the pressure sensor and the infrared sensor through the central processing unit, and uses a dynamic time warping algorithm and a threshold judgment algorithm to comprehensively calculate and obtain the current patient status information.

[0019] Preferably, the abnormal alarm module is used to make a judgment based on the patient status information obtained in the sensor data analysis module. When the pressure sensor and the safety grating are triggered respectively, the abnormal alarm information will be transmitted to the nursing station, and the control panel and the nursing station will change the lamp display mode accordingly, including the following states:

[0020] Green light: indicates that the bed is in daytime mode;

[0021] Yellow light: When the guardrail is lowered by external force, the yellow light comes on; when the guardrail is raised, the yellow light goes out;

[0022] Red light: The infrared sensor in the safety light grid is triggered and the red light turns on; the caregiver turns it off manually at the nursing station or closes it in the mobile phone app.

[0023] Flashing red light: When the pressure sensor on the bed surface detects that the patient is not in bed, the red light flashes; the nursing staff can turn it off manually at the nursing station or close it in the mobile phone app.

[0024] Preferably, the intelligent remote monitoring module uses a small program to display the current bed status data and abnormal alarm, including the following control interface:

[0025] First interface, ward module; the priority level of alarm lights flashing > red light > yellow light. When two beds in the same ward trigger the yellow and red alarm systems respectively, it is directly determined that the current ward is in a red alarm state;

[0026] The second interface is the bed module. Click the flashing ward icon to enter the bed interface, where you can see which bed triggers which type of alarm system.

[0027] When the red light flashes, the portable data terminal will vibrate, and the applet has the function of canceling the alarm.

[0028] Preferably, the data analysis module is used to record the time of each torque sensor, pressure sensor, safety grating induction triggering and the patient's bed number, and based on the analysis of these data, generate a corresponding line graph to display in the intelligent remote monitoring module.

[0029] Working principle: When the patient wants to get out of bed at night without following the doctor's advice:

[0030] If the railing is lowered by yourself, the sensor inside the smart railing detects that the railing is subjected to abnormal external force and transmits a signal to the control unit. The yellow light of the corresponding bed in the nursing station and the logged-in APP (mini program) will light up. The nursing staff can inspect it immediately, lift the railing, and the yellow light will go out.

[0031] If the patient does not lower the railing and attempts to get out of bed by moving his body to the edge of the bed, when his legs are hanging in the air, the infrared alarm system will be triggered. The infrared alarm system will transmit the signal to the control unit, and the red light of the corresponding bed will light up on the nursing station and the APP (applet) in the logged-in state, so that the nursing staff can go over to inspect as soon as possible. The red light can be turned off at the nursing station or on the mobile phone.

[0032] If the patient has left the bed, the pressure sensor at the bottom of the bed detects that the patient has left the bed, and the sensor immediately transmits the signal to the control unit. The red light of the corresponding bed in the nursing station and the logged-in APP (applet) starts flashing, and the nursing staff can go over to inspect as soon as possible. The flashing red light can be turned off at the nursing station or on the mobile phone.

[0033] At the same time, when the patient needs to be transported to other wards or testing rooms, the road condition cannot be guaranteed to be absolutely straight during transportation. Therefore, when there is a certain degree of bumps on the road surface, the bulge on the ground will push the elastic support rod above through the universal wheel to produce elastic deformation to buffer the impact force. At the same time, when the elastic support rod and the bed body produce relative movement in the vertical plane, the load-bearing rod will also be squeezed to push the movable block to move into the damping bin. At this time, the damping fluid inside the damping bin will form motion damping of the movable block due to its own properties, thereby achieving shock absorption effect through buffering and damping, avoiding secondary injuries caused by collision to orthopedic patients during transportation.

[0034] The present invention provides an intelligent monitoring bed and monitoring system, which have the following beneficial effects:

[0035] 1. The present invention can detect the safety of patients by setting up a data sensing module and a sensor data analysis module: by timely detecting the patient's abnormal behavior and issuing an alarm, it can effectively prevent the patient from getting out of bed without authorization and causing secondary injuries such as falls, thereby ensuring the safety of orthopedic patients during hospitalization.

[0036] 2. The elastic telescopic rod, sliding rod, elastic support rod, movable block, damping chamber and load-bearing rod provided in the present invention can buffer the impact force and form motion damping through the elastic support rod and the damping fluid inside the damping chamber when the patient needs to be transferred and there is a certain degree of bumpiness on the road surface, thereby reducing the impact and vibration borne by the patient lying on the bed and improving the safety of orthopedic patients during transfer.

[0037] 3. The present invention can optimize the work efficiency of medical staff by setting up an abnormal alarm module: medical staff can be informed of the patient's abnormal condition at the first time, without regular inspections or waiting for patient calls, reducing the medical staff's work blind spots and enabling medical staff to care for patients more accurately.

The outer surface of the control panel 5 is provided with a digital display screen and control buttons. There are a plurality of torque sensors 8, and the plurality of torque sensors 8 are respectively located under each group of ribs of the guardrail 6. The torque sensor 8 can detect the current position information of the guardrail 6.

[0049] The two groups of infrared gratings 7 are aligned with each other, and detect whether the patient gets out of bed by emitting infrared light.

[0051] Please see attached Figure 5 , a monitoring system for an intelligent monitoring bed, including the following modules:

[0052] The data sensing module is connected to each group of sensor devices inside the intelligent monitoring bed, and receives and translates the data signals transmitted from each group of sensors;

[0053] The sensor data analysis module receives the data from the data sensor module, analyzes and processes the data, and uses algorithms and models to determine the patient status reflected by the data;

[0054] The abnormal alarm module triggers the alarm function according to the patient status determined by the sensor data analysis module, including when the patient leaves the bed;

[0055] Intelligent remote monitoring module allows medical staff to monitor the patient's condition remotely and in real time through the network, and transmit the data of each bed to the hospital's monitoring center, the digital display screen of the nurse station and the mobile devices of medical staff;

[0056] The data analysis module records the time of each triggering of the guardrail, pressure sensor, and infrared sensor, as well as the patient's bed number, and conducts a comprehensive analysis of the data collected over a period of time to generate a patient status report, including the patient's activity patterns and frequency of leaving bed.

[0057] The data sensing module includes multiple groups of sensors, including pressure sensors and infrared sensors, which are used to monitor the patient's physiological parameters and behavioral activities in real time. The pressure sensor is used to detect whether the patient has left the bed. When the pressure above is significantly reduced, it is determined that the patient has left the bed. The infrared sensor is located inside the safety gratings on both sides in a counter-radiation manner. When the counter-radiated infrared light is blocked, it is determined that the patient is in a state of getting out of bed. The torque sensor is used to detect the position information of the guardrail and determine whether the guardrail is currently in a raised or lowered state.

[0058] The sensor data analysis module includes a central processing unit, and the central processing unit integrates the data from the pressure sensor and the infrared sensor, and uses the dynamic time warping algorithm and the threshold judgment algorithm to comprehensively calculate and obtain the current patient status information. The algorithm is as follows:

[0059] Set the threshold range of the pressure sensor and infrared sensor. When the pressure value detected by the pressure sensor is lower than a certain lower threshold, it is preliminarily judged that the patient may leave the bed. At the same time, when the infrared light of the safety grating is blocked, it is also used as a basis for the patient to leave the bed.

[0060] Assume that the pressure sensor detection value is p, and the lower limit of pressure is set to P i , when p<P i When the error occurs, a preliminary abnormality judgment is triggered;

[0061] For the signal strength of the infrared incident light of the safety grating, set the infrared signal strength threshold to I i , when I<I i When , the preliminary judgment is also triggered;

[0062] Analyze the data series of the pressure sensor and infrared sensor signal strength over time. By calculating the similarity between the two time series, determine the degree of difference between the current patient status and the normal bed status. If the similarity is lower than a certain threshold, it is determined that the patient's bed leaving status is abnormal:

[0063] Suppose there are two time series A={a1,a2,…,a m} and B={b1,b2,…,b m}, where a i and b j Represent the detection values ​​of the sensors at different times, and construct an m×n matrix D, where D(i, j) represents a i and b j , the distance between them;

[0064] Then, a path from (1,1) to (m,n) is found through dynamic programming, which minimizes the cumulative distance on the path. The calculation formula for the cumulative distance is:

[0065] d(i,j)=D(i,j)+min{d(i-1,j-1),d(i-1,j),d(i,j-1)};

[0066] The final DTW distance is d(m, n). If the DTW distance is greater than the set threshold, it is judged as an abnormal state.

[0067] The abnormal alarm module is used to make judgments based on the patient status information obtained from the sensor data analysis module. When the pressure sensor and the safety grating are triggered, the abnormal alarm information will be transmitted to the nursing station. At the same time, the control panel and the nursing station will change the lamp display mode accordingly, including the following states:

[0068] Green light: indicates that the bed is in daytime mode;

[0069] Yellow light: When the guardrail is lowered by external force, the yellow light comes on; when the guardrail is raised, the yellow light goes out;

[0070] Red light: The infrared sensor in the safety light grid is triggered and the red light turns on; the caregiver turns it off manually at the nursing station or closes it in the mobile phone app.

[0071] Flashing red light: When the pressure sensor on the bed surface detects that the patient is not in bed, the red light flashes; the nursing staff can turn it off manually at the nursing station or close it in the mobile phone app.

[0072] There is a "Day Mode" button on the control panel. When the patient needs to get out of bed normally accompanied by medical staff (such as going to the bathroom, doing rehabilitation activities, etc.) or the medical staff needs to change the dressing, etc., they can press this button to turn off the night mode function. At the same time, in order to prevent patients from operating it by mistake at night, this button is designed to be pressed for a long time to trigger the day mode.

[0073] The intelligent remote monitoring module uses a small program to display the current bed status data and abnormal alarm, including the following control interface:

[0074] First interface, ward module; the priority level of alarm lights flashing > red light > yellow light. When two beds in the same ward trigger the yellow and red alarm systems respectively, it is directly determined that the current ward is in a red alarm state;

[0075] The second interface is the bed module. Click the flashing ward icon to enter the bed interface, where you can see which bed triggers which type of alarm system.

[0076] When the red light flashes, the portable data terminal will vibrate, and the applet has the function of canceling the alarm.

[0077] The data analysis module is used to record the time of each torque sensor, pressure sensor, and safety grating sensor triggering and the patient's bed number, and based on the analysis of these data, generate a corresponding line graph and display it in the intelligent remote monitoring module so that more targeted nursing measures can be taken, such as adjusting the nursing rounds time.

[0078] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
