For example, patients may not follow medical advice to get out of bed, adversely affecting their health; or they may experience falls or other accidents while getting out of bed and moving around. All of these can negatively impact a patient's health. However, existing call systems are insufficient to meet the need for monitoring patients' movements while out of bed. Utility Model Content

[0029] It should also be noted that the division of multiple embodiments in this utility model is only for the convenience of description and should not constitute a special limitation. Features in various embodiments can be combined and referenced in each other without contradiction.
[0030] During hospitalization, patients typically require care from family members or medical staff. However, it is difficult for family members or medical staff to provide 24-hour care. Therefore, without supervision, patients may get out of bed and move around on their own, which can adversely affect their health. Thus, it is necessary to monitor and alert staff regarding patients' movements outside the bed.
[0031] Based on this, see Figure 1This utility model embodiment provides an out-of-bed sensing alarm system 70, including a hospital bed 10, a sensing component 20, an information component 30, and an alarm terminal 40. The hospital bed 10 includes a bed board 11; the sensing component 20 includes a pressure sensor 21, an infrared sensor 22, an acceleration sensor 23, and a sensing waist belt 24. The pressure sensor 21 is disposed on the bed board 11, the infrared sensor 22 is disposed on the side of the hospital bed 10, and the acceleration sensor 23 is disposed on the sensing waist belt 24; the information component 30 is disposed on the hospital bed 10, specifically, the information component 30 is disposed on the bed frame of the hospital bed 10, or the information component 30 is disposed on the side of the bed board 11 facing the bed floor. Pressure sensor 21, infrared sensor 22, and acceleration sensor 23 are wirelessly connected to information component 30. Information component 30 generates alarm information based on the information sensed by sensing component 20. The alarm information includes patient status risk information generated from the information sensed by sensing component 20, as well as the patient's ID (Identity Document) information and bed number information of bed 10, thus facilitating the management of patient risk by medical staff. Alarm terminal 40 is signal-connected to information component 30 and has an alarm state. Alarm terminal 40 is used to receive alarm information and enter the alarm state. Information component 30 and alarm terminal 40 can be connected wirelessly or wired. Wireless connection facilitates disassembly, replacement, and relocation, while wired connection provides stable data transmission and lower cost. Specifically, the sensing component 20 and the information component 30 are wirelessly connected using the Wi-Fi wireless transmission protocol, which provides wide coverage and convenient connection; or the sensing component 20 and the information component 30 are wirelessly connected using the Bluetooth wireless transmission protocol, which can reduce costs; furthermore, both Wi-Fi and Bluetooth wireless transmission protocols are used for wireless connection, for example, the pressure sensor 21 and the infrared sensor 22 are wirelessly connected to the information component 30 using the Wi-Fi wireless transmission protocol, and the accelerometer 23 is wirelessly connected to the information component 30 using the Bluetooth wireless transmission protocol.
[0032] The pressure sensor 21 senses pressure information and converts it into an electrical signal, which is then output to the information component 30. The pressure sensor 21 is mounted on the bed board 11 to monitor the pressure information of the patient on the bed board 11. For example, the bed board 11 has a groove, and the pressure sensor 21 is placed in the groove, or rather, the pressure sensor 21 protrudes from the groove to sense pressure; alternatively, the pressure sensor 21 is adhered to the bed board 11 with adhesive. Specifically, the pressure sensor 21 can be a piezoresistive sensor, a piezoelectric sensor, etc. The infrared sensor 22 is located on the side of the bed 10. Specifically, the infrared sensor 22 can be located in the middle of the bed frame along the length of the bed 10, and its height from the ground is, for example, 60cm or 70cm; the infrared sensor 22 is tilted downwards at 15° to cover the patient's lower limb movement area. Infrared sensor 22 emits infrared signals to determine whether the patient is on the side of the bed 10. It also determines the distance between the patient and the bed 10 by the intensity of the reflected infrared signal, and outputs this distance information to information component 30. Specifically, infrared sensor 22 can be an infrared rangefinder sensor, which can sense and measure the distance to the patient. A sensing belt 24 is positioned on the patient's torso, specifically, for example, in the center of the abdomen. This allows the accelerometer 23 on the belt to monitor the patient's torso acceleration and tilt angle, transmitting this information to information component 30. Specifically, for example, the threshold for accelerometer 23 is set to indicate that the patient is turning over if the tilt angle exceeds 30° and the duration is >2 seconds before or after a change in acceleration. Compared to the arms, torso movements are more stable, resulting in less noise collected by the accelerometer 23, which helps information component 30 more accurately determine the patient's activity status. Specifically, the accelerometer 23 can be a capacitive accelerometer, an inductive accelerometer, a strain gauge accelerometer, a piezoresistive accelerometer, or a piezoelectric accelerometer. The accelerometer 23 and the sensing belt 24 are, for example, each equipped with a mating buckle, allowing for easy assembly and disassembly. The accelerometer 23 can be powered by, for example, a rechargeable battery, further enhancing its convenience.
[0033] Information component 30 collects information from pressure sensor 21, infrared sensor 22, and accelerometer 23, and processes the collected information to assess the patient's condition. If it determines that the patient is engaging in a risky behavior, such as getting out of bed, it sends an alarm message to alarm terminal 40.
[0034] The alarm terminal 40 has an alarm state. When the alarm terminal 40 receives the alarm information output by the information component 30, it switches to the alarm state to issue an alarm, thereby reminding medical staff to deal with the situation in a timely manner and reduce the probability of patients suffering accidental injuries, such as falls.
[0035] The following describes the bed-mounted sensor alarm system 70 provided by this utility model in detail with some specific embodiments. It should be noted that the following embodiments do not constitute a specific limitation on this utility model.
[0036] When the patient is lying on the bed 10, the pressure sensor 21 installed on the bed board 11 can sense the patient's pressure information and transmit it to the information component 30. The infrared sensor 22 installed on the side of the bed 10 cannot detect the patient, and therefore also transmits this information to the information component 30. Furthermore, the accelerometer 23 detects that the patient's trunk acceleration is very small or zero, and the patient's trunk tilt angle is also small, transmitting the patient's trunk acceleration and tilt angle information to the information component 30. The information component 30 processes the information and determines that the patient has not gotten out of bed; for example, if the patient is lying flat, no alarm is issued. Therefore, the alarm terminal 40 does not sound an alarm.
[0037] When the patient turns over in bed 10, pressure sensor 21 detects changes in the patient's pressure and transmits this information to information component 30. Infrared sensor 22, however, cannot detect the patient and therefore also transmits this information to information component 30. At this time, accelerometer 23 detects a certain acceleration in the patient's torso, and the torso's tilt angle does not change continuously. It then transmits the patient's torso acceleration and tilt angle information to information component 30. Information component 30 processes this information and determines that the patient has not gotten out of bed; for example, if the patient is turning over, no alarm is triggered. Therefore, alarm terminal 40 does not sound an alarm.
[0038] When a patient lies on bed 10 but accidentally obstructs the view, causing infrared sensor 22 to mistakenly detect the patient, the information component 30 can determine that the patient has not gotten out of bed and therefore does not issue an alarm. Since the patient's torso acceleration is very small and pressure sensor 21 can still detect the patient's pressure, the alarm terminal 40 will not trigger an alarm.
[0039] When the patient gets out of bed, pressure sensor 21 detects changes in the patient's pressure and transmits this information to information component 30. Simultaneously, infrared sensor 22 monitors the patient from the side of bed 10 and measures the distance between the patient and bed 10, transmitting this data back to information component 30. Furthermore, due to trunk movement during the patient's ascent, acceleration sensor 23 detects significant and fluctuating trunk acceleration and trunk tilt angle. Information component 30 collects and processes the information from pressure sensor 21, infrared sensor 22, and acceleration sensor 23, determining that the patient is getting out of bed and issuing an alarm signal. Upon receiving the alarm signal, alarm terminal 40 switches to alarm mode to alert medical staff to address the patient's risky behavior, thereby reducing the probability of accidental injury. Additionally, infrared sensor 22 can monitor the distance between the patient and bed 10 via infrared signals, enabling dynamic monitoring of the patient.
[0040] When the patient gets out of bed and moves around, the accelerometer 23 and infrared sensor 22 can also monitor the patient's movement. For example, when the patient falls, the accelerometer 23 detects a large acceleration in the patient's torso and a large change in the patient's torso tilt angle. At the same time, the infrared sensor 22 can detect a change in the patient's distance from the bed. The information component 30 integrates and processes the information detected by the accelerometer 23 and infrared sensor 22 to determine that the patient is at risk of falling, and then issues an alarm message, causing the alarm terminal 40 to switch to alarm mode to alert medical staff to deal with the patient's risky behavior in a timely manner, thereby reducing the probability of accidental injury to the patient.
[0041] Understandably, the judgment thresholds of each sensor can be adjusted according to the patient's actual situation. For example, when the data from pressure sensor 21 is below the threshold of 20kg for 3 seconds, infrared sensor 22 detects a target within 0.5m for 2 seconds, and acceleration sensor 23 detects an acceleration greater than 0.5g, information component 30 determines that the patient should get out of bed and generates an alarm message.
[0042] The ambulation alarm system 70 provided in this embodiment of the invention senses patient status information through a pressure sensor 21, an infrared sensor 22, and an accelerometer 23. This information is processed by an information component 30 to determine the patient's movement as they get out of bed. If the system detects the patient is ambulating, it issues an alarm signal. Upon receiving the alarm signal, the alarm terminal 40 activates an alarm to alert medical staff for timely intervention. The accelerometer 23 is mounted on the patient's torso via a belt, reducing the noise signal it collects and allowing the information component 30 to more accurately assess the patient's activity. The ambulation alarm system 70 can automatically identify and trigger alarms for risky patient behaviors without requiring active intervention from the patient. This system monitors the patient's movement as they get out of bed and alerts them to potential risks, thereby reducing the probability of accidental injury and minimizing health risks.
[0043] In some specific embodiments, the alarm terminal 40 includes a signal receiving device, a first speaker, and an LED light, with the signal receiving device connected to the speaker and the LED light respectively. When the signal receiving device receives an alarm signal, the alarm terminal 40 switches to alarm mode, and the signal receiving device transmits the alarm signal to the first speaker and the LED light. After receiving the alarm signal, the first speaker emits an alarm sound, and the LED light illuminates to remind medical staff to promptly address the patient's risk situation.
[0044] Specifically, the alarm terminal 40 also includes a vibrator and a switch. The vibrator, the first speaker, and the LED light are each connected to the signal receiving device via the switch. The switch controls the connection status of the vibrator, the first speaker, and the LED light with the signal receiving device. Thus, different alarm modes can be selected via the switch, helping the alarm terminal 40 adapt to different usage scenarios. For example, at night, the switch can be used to switch the connection between the vibrator and the signal receiving device. When the signal receiving device receives an alarm signal, the vibrator vibrates to alert medical personnel to promptly address the patient's risky behavior. It is understood that the switch can also connect two or all of the vibrator, the first speaker, and the LED light to the signal receiving device, thereby providing the alarm terminal 40 with more diverse alarm modes, helping it adapt to different usage scenarios.
[0045] In some embodiments, see Figure 1The sensing component 20 also includes a sensing wristband 25, a heart rate sensor 26, and a blood oxygen sensor 27. The heart rate sensor 26 and blood oxygen sensor 27 are respectively mounted on the sensing wristband 25 and are wirelessly connected to the information component 30 via the sensing wristband 25. Patients can wear the sensing wristband 25; the heart rate sensor 26 monitors the patient's heart rate, and the blood oxygen sensor 27 monitors the patient's blood oxygen levels. Thus, the information component 30 can combine the patient's heart rate and blood oxygen information to make a more accurate judgment of the patient's condition, thereby achieving dual monitoring of the patient's movements and physiological indicators, improving the accuracy of alarm information generated by the information component 30. Furthermore, the patient's risk level can be classified based on their heart rate and blood oxygen information. For example, when the information component 30 receives the patient's heart rate and blood oxygen information, it combines it with information collected by other sensors in the sensing component 20 to generate different levels of alarms. This allows medical staff to prioritize high-risk alarms, reduce unnecessary patrols, and improve nursing efficiency.
[0046] In some embodiments, see Figure 1 The sensing component 20 also includes a millimeter-wave radar 28, and the hospital bed 10 also includes a headboard 12. The millimeter-wave radar 28 is installed on the headboard 12 and is wiredly connected to the information component 30.
[0047] The millimeter-wave radar 28 can monitor the patient's breathing and heart rate, transmitting the data to the information component 30. This allows the information component 30 to obtain more information to assess the patient's condition, making its judgments more accurate. Furthermore, the millimeter-wave radar 28 enables non-contact monitoring, contributing to greater patient comfort during hospitalization. It also helps protect patient privacy. Specifically, the millimeter-wave radar 28 is fixed to the center of the top of the headboard 12, 40cm above the bed board 11. The operating frequency of the millimeter-wave radar 28 is, for example, 60GHz, with a detection angle of 120°, a detection distance of 0.2-5m, and a sampling frequency of 100Hz. This allows for better patient monitoring. The millimeter-wave radar 28 can be a medical-grade millimeter-wave radar, such as the IWR1642 or IWR6843.
[0048] In some embodiments, see Figure 2 The pressure sensors 21 are multiple. The hospital bed 10 includes a headboard 12, and the bed board 11 has a headrest area 111 near the headboard 12, and a sensing area 112 on the side of the headrest area 111 away from the headboard 12. The pressure sensors 21 are arrayed in the sensing area 112. Specifically, the size of the sensing area 112 is, for example, 90cm × 150cm, and is adapted to the size of the bed board 11. The pressure sensors 21 are spaced apart in the sensing area 112 and distributed in an array.
[0049] Understandably, when a patient is lying in bed, their head is located in the headrest area 111, while their torso and lower limbs are located on the side of the headrest area 111 away from the headboard 12, i.e., the sensing area 112. Since the torso and lower limbs move more when the patient moves on the bed 10, the pressure sensor array 21 covering the patient's torso and lower limb areas helps the pressure sensor array 21 obtain more pressure information. This helps the information component 30 make a more accurate judgment of the patient's state and issue alarm information more precisely. For example, when the patient turns over or gets out of bed, the pressure information sensed by the pressure sensors 21 at different locations in the pressure sensor array 21 is different. Therefore, the information component 30 can distinguish between different actions based on this difference in pressure information, thereby more accurately judging the patient's dynamics and issuing alarm information more precisely.
[0050] In some embodiments, see Figure 1 The information component 30 includes an information processing device 31 and a data transmission device 32. The information processing device 31 is connected to the data transmission device 32, and the data transmission device 32 is connected to both the sensing component 20 and the alarm terminal 40. The information processing device 31 generates alarm information based on the information sensed by the sensing component 20. The data transmission device 32 receives and transmits data, for example, receiving information sensed by the sensing component 20 and sending an alarm signal. In some specific embodiments, the information processing device 31 includes a host computer with an integrated processing chip, which processes the information sensed by the sensing component 20.
[0051] In some embodiments, see Figure 1 The information component 30 also includes a noise processing device 33, which is connected to the data transmission device 32 and the information processing device 31. The noise processing device 33 filters the information sensed by the sensing component 20 collected by the data transmission device 32. During sensor monitoring, the sensor collects a lot of noise information, which is mixed with the valid information, thus interfering with the information component 30. Therefore, the information component 30 filters the sensed information to remove the noise information, improving the signal-to-noise ratio, allowing the information component 30 to make a more accurate judgment on the patient's condition based on more effective information. In some specific embodiments, the noise processing device 33 includes a device integrating a noise processing chip, which is used to filter the sensed information. Specifically, the noise processing device 33 can employ a finite impulse response filter, an adaptive filter, or a Kalman filter.
[0052] In some embodiments, see Figure 1The information component 30 also includes an information storage device 34, which is connected to the data transmission device 32 and the information processing device 31 respectively. The information storage device 34 is used to store and transmit patient health information. The information storage device 34 can store patient physical condition information and can receive alarm information from the information processing device 31. It can then match the patient's physical condition information with the patient ID and bed number in the alarm information and transmit this information to the data transmission device 32. The data transmission device 32 then transmits the alarm information and the patient's physical condition information together to the alarm terminal 40. This allows medical staff to promptly determine the patient's current condition based on the alarm information and the patient's physical condition information, thus helping them to quickly handle emergency situations.
[0053] In some embodiments, see Figure 1 The bed-mounted alarm system 70 also includes a voice interaction component 50, which is installed on the hospital bed 10 and used for voice communication with the alarm terminal 40. Specifically, the alarm terminal 40 includes a first speaker, a first microphone, and a first voice communication device, which is wired to the first speaker and the first microphone. The voice interaction component 50 includes a second voice communication device, a voice sensing device, a second speaker, and a second microphone, which are wired to the voice sensing device, the second speaker, and the second microphone. The voice sensing device is also wired to the second microphone. The first voice communication device is connected to the second voice communication device, and the connection between them can be wireless or non-wireless. The voice sensing device is used to sense sound to activate the first and second voice communication devices, which are then used for voice communication. When the voice sensing device senses the patient speaking, it activates the first and second voice communication devices to conduct voice communication. The patient can communicate with medical staff through the second speaker and the second microphone.
[0054] In this way, patients and medical staff can communicate in a timely manner via voice, which makes it easier for medical staff to understand the patient's condition and for patients to call for medical staff, especially for patients with physical disabilities.
[0055] In some embodiments, see Figure 1The alarm terminal 40 includes a fixed terminal 41 and a mobile terminal 42. Both the fixed terminal 41 and the mobile terminal 42 are connected to the information component 30 and are used to receive alarm information to switch to alarm mode. Specifically, the fixed terminal 41 is installed at the nurses' station, and the mobile terminal 42 is carried by medical staff. In this way, both the mobile terminal 42 and the fixed terminal 41 can receive alarm information and trigger alarms, helping to reduce the likelihood of alarms going unattended and enabling medical staff to handle alarms promptly. For example, the fixed terminal 41 can be a host computer connected to a screen. The host computer and the information component 30 can be connected via a wired connection or wirelessly via a wireless transmission terminal 60, such as a Wi-Fi device. When the host computer receives alarm information, it displays the alarm on the screen. The host computer can also be connected to a speaker and LED lights to provide audible and visual alarms when alarm information is received, thus better alerting medical staff. The mobile terminal 42 can be a mobile phone, which is wirelessly connected to the information component 30. When alarm information is received, the mobile phone can ring or vibrate to alert medical staff to take action.
[0056] In some embodiments, see Figure 1 The bed-mounted alarm system 70 also includes a wireless transmission terminal 60, which is mounted on the alarm terminal 40 and the information component 30. The wireless transmission terminal 60 is wired to both the alarm terminal 40 and the information component 30, and wirelessly connected to both via the wireless transmission terminal 60. Specifically, the wireless transmission terminal 60 is a Wi-Fi device that converts the information generated by the alarm terminal 40 and the information component 30 into wireless signals for transmission. This makes wireless transmission via the wireless transmission terminal 60 more convenient and facilitates the installation and removal of the equipment.
[0057] In some specific embodiments, the bed-mounted alarm system 70 includes a camera, and the hospital bed 10 includes a headboard 12. The camera is mounted on the headboard 12 and connected to the alarm terminal 40. The video image data from the camera can be transmitted to the alarm terminal 40. Thus, when the alarm terminal 40 receives an alarm message and enters an alarm state, medical staff can more intuitively see the patient's dynamics through video images on the alarm terminal 40, thereby quickly assessing the patient's condition and providing better treatment, reducing the patient's health risks.
