Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a bed rail with an alarm system to prevent falls and people from getting lost. Background Technology

[0002] In the field of medical care, bed rails are an important safety measure for patients who need to stay in bed for extended periods due to their condition and are prohibited from getting out of bed. While existing bed rails can provide some physical protection and reduce the possibility of patients falling out of bed, there are still many safety hazards and technical deficiencies that need to be addressed in practical applications, making it difficult to meet the complex clinical nursing needs.

[0003] Specifically, current bed rails and related monitoring methods exhibit significant limitations when dealing with patients with poor compliance. These patients, including those with cognitive impairment, restlessness, dementia, or mental disorders, often exhibit voluntary or involuntary dangerous behaviors. For example, they may operate manually adjustable bed rails themselves, lowering them by unlocking or forcibly breaking them, or squeezing through gaps between the rails, leading to falls and other accidents. This can not only worsen their condition and increase their financial burden but may even endanger their lives. Particularly in the care of pediatric or elderly patients, the safety hazards posed by excessively large gaps between bed rails are more pronounced due to their relatively small size or limited mobility, further increasing the risk of accidents.

[0004] Meanwhile, existing technologies have significant shortcomings in intelligent monitoring and proactive alarm functions. Current bed rails serve only as passive physical barriers, lacking the ability to sense the patient's condition and unable to detect whether the patient is lying down, whether they are attempting to climb over the rails, or whether they are at risk of falling out of bed. This makes it difficult for medical staff and caregivers to monitor abnormal patient behavior in real time, forcing them to rely on manual observation to detect dangers. This results in a severe delay in alarm response, often only addressing the issue after an accident has occurred, thus failing to effectively prevent accidents.

[0005] Furthermore, for special patients such as those with dementia or mental disorders, current technology lacks effective means to restrict them from leaving their beds without authorization. Patients may get out of bed on their own at night when no one is accompanying them or when the caregiver is negligent. Moreover, due to the lack of location tracking function, it is difficult to quickly find patients once they leave the monitoring range, increasing the risk of patients getting lost.

[0006] In nursing care, current technology relies heavily on human supervision, requiring caregivers to monitor patients throughout the entire process. However, this approach is inefficient, and caregivers are prone to gaps in protection due to fatigue, negligence, or other reasons. This not only increases medical costs but also fails to ensure the continuity and reliability of protection, leaving patient safety still at significant risk.

[0007] Further analysis reveals that the deficiencies of current clinical bed rails and monitoring equipment are mainly reflected in the following aspects:

[0008] Firstly, regarding the design of the bed rail structure, the manually adjustable bed rails use a mechanical fixing method, and the spacing between the bed rails is too large, resulting in insufficient reliability. Secondly, in terms of the intelligent monitoring and protection system, it lacks both the ability to monitor abnormal patient behavior in real time and the ability to proactively alarm and track and locate patients, making it impossible to promptly remind medical staff and caregivers to take intervention measures.

[0009] Therefore, there is an urgent need to develop a bed rail with an alarm to prevent falls and people from getting lost, in order to solve the above problems.

[0010] The statements herein provide only background information relating to this invention and do not necessarily constitute prior art. Utility Model Content

[0011] The purpose of this invention is to provide a bed rail that prevents falls and loss of belongings, and can solve the problems of insufficient structural reliability and inability to perform real-time monitoring and alarm in existing bed rails.

[0012] To achieve the above objectives, this utility model provides a bed rail with an anti-fall-off and anti-lost alarm system, comprising:

[0013] Bed frame body;

[0014] Bed railings, including guardrails on both sides of the bed frame and guardrails at the feet of the bed frame, are used to protect patients from falling out of bed.

[0015] The mattress is mounted on the bed frame.

[0016] The intelligent monitoring system includes a pressure sensor, an infrared monitor, an audible and visual alarm device, and a smart ankle bracelet. This intelligent monitoring system is installed on the mattress and bed rails and communicates with the medical care system to realize the perception, monitoring, and alarm for patients leaving the bed.

[0017] A smart sensor is installed at the bottom of the bed frame and communicates with the smart foot ring to sense the distance between the patient and the bed rails.

[0018] Optionally, multiple pressure sensors are provided, which are arranged at equal intervals on both sides inside the mattress to monitor the patient's lying, sitting, or standing status in real time.

[0019] Optionally, two infrared monitors are provided, one on each side of the guardrail, to determine whether a patient has climbed over or crawled under the guardrail by the strength of the infrared detection signal.

[0020] Optionally, the audible and visual alarm device is installed on the bed frame body and is communicatively connected to each of the pressure sensors and each of the infrared monitors, so as to trigger the audible and visual alarm device through pressure signals and infrared detection signals.

[0021] Optionally, when the pressure collected by all pressure sensors drops sharply to 0, indicating that the patient has completely left the bed, the pressure signal is transmitted to the audible and visual alarm device to trigger the alarm.

[0022] Optionally, when the infrared detection signal generated by the infrared monitor changes abruptly from the first infrared detection signal to the second infrared detection signal and then disappears to 0, it indicates that the patient has completely left the bed. The infrared detection signal is transmitted to the audible and visual alarm device to trigger the alarm. The intensity of the first infrared detection signal is less than that of the second infrared detection signal.

[0023] Optionally, the smart ankle bracelet is worn on the patient's feet and communicates with a smart sensor at the bottom of the bed frame to sense the distance between the patient and the bed rails.

[0024] Optionally, the intelligent sensor is communicatively connected to the audible and visual alarm device. When the distance between the patient and the bed rails exceeds a preset safety value, the intelligent sensor sends the detected distance signal to the audible and visual alarm device to trigger the alarm.

[0025] Optionally, the audible and visual alarm device is communicatively connected to the medical care system to transmit alarm signals to the medical care system.

[0026] Optionally, the alarm information from the sound and light alarm device triggered by the intelligent sensor carries the distance of the patient from the bed and the patient's own location information, and the medical care system can be used to locate and track the patient who has left the bed.

[0027] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The present invention provides a bed rail for preventing falls and getting lost. By setting pressure sensors, infrared monitors, intelligent sensors and sound and light alarm devices on the bed rail, it realizes real-time monitoring of the patient's lying state and automatic alarm and location tracking when the patient leaves the bed.

[0029] 2. The bed rail provided by this utility model, which provides an anti-fall-out and anti-lost alarm, improves patient safety and avoids dangerous situations such as falling out of bed, stumbling, and getting lost; reduces the burden on nursing staff and improves hospital management efficiency; and ensures that nursing staff can respond and take measures in a timely manner through remote connection between the bed rail and the medical station and the mobile phones of medical staff.

[0033] This utility model provides a bed rail with an alarm to prevent patients from falling out of bed and getting lost. This bed rail is suitable for patients with poor compliance (including patients with cognitive impairment, restlessness, dementia or mental abnormalities). These patients generally cannot get out of bed on their own, but there are cases where patients forcibly break, climb over, or crawl through the bed rail to get out of bed. Therefore, it is necessary to provide such patients with a bed rail that can detect whether the patient is in bed and can sound an alarm when the patient gets out of bed on their own.

[0034] like Figure 1 As shown, the anti-fall bed and anti-lost alarm bed rails include: a bed frame body 100; a bed rail surround 200, including guardrails 210 on both sides of the bed frame body 100 and a guardrail 220 at the foot of the bed frame body 100, the bed rail surround 200 is used to protect the patient from falling out of bed; a mattress 300, which is installed on the bed frame body 100; an intelligent monitoring system, including a pressure sensor 410, an infrared monitor 420, an audible and visual alarm device, and a smart ankle bracelet, the intelligent monitoring system is installed at the mattress 300 and the bed rail surround 200, and is connected to the medical care system to realize the perception, monitoring and alarm of the patient leaving the bed; and a smart sensor 430, which is installed at the bottom of the bed frame body 100 and is connected to the smart ankle bracelet to sense the distance between the patient and the bed rails.

[0035] Multiple pressure sensors 410 are arranged at equal intervals on both sides inside the mattress 300 to monitor the patient's lying position in real time. When the patient is lying flat, all pressure sensors 410 on both sides can detect the corresponding pressure value; when the patient is lying on their side, only multiple pressure sensors 410 on one side can detect the corresponding pressure value; when the patient is sitting up, the pressure sensors 410 on both sides near the guardrail 220 can detect the corresponding pressure value; when the patient falls out of bed or climbs over the guardrail 210, all pressure sensors 410 on both sides cannot detect the pressure value.

[0036] In a specific embodiment of this utility model, the pressure sensor 410 is a high-sensitivity pressure sensor 410; specifically, the pressure sensor 410 adopts the FlexiForce A201 model pressure sensor 410.

[0037] Two infrared monitors 420 are provided, which are respectively installed on the guardrails 210 on both sides to detect whether the patient climbs over or crawls under the guardrails 210 of the bed railing 200.

[0038] Specifically, when the patient is lying normally on the bed rails, because the patient is not fully close to the rails 210, a small amount of infrared radiation emitted by the patient is received by the infrared detector 420. At this time, the infrared detector 420 can only generate a weak first infrared detection signal. However, when the patient is crossing over or crawling out of the rails 210, a large amount of infrared radiation emitted by the patient is received by the infrared detector 420. At this time, the infrared detector 420 generates a very strong second infrared detection signal. Furthermore, when the patient completely crosses over / crawls through the rails 210 and then completely leaves the bed rails, the infrared detector 420 does not detect infrared radiation from the human body and generates almost no infrared detection signal. Therefore, during the process of the patient moving from a normal bed position to climbing over / crawling through the guardrail 210 and then completely leaving the bed, the infrared monitor 420 first detects the first infrared detection signal, then detects the second infrared detection signal (the intensity of the first infrared detection signal is less than that of the second infrared detection signal), until the infrared detection signal disappears, that is, the infrared detection signal suddenly changes from weak to extremely strong, and then the signal value drops to 0.

[0039] In a specific embodiment of this utility model, the infrared monitor 420 is an HC-SR505 model infrared monitor 420. This model of infrared monitor 420 is a sensor based on passive infrared (PIR) technology. Its working principle mainly relies on detecting changes in infrared radiation emitted by the human body or other objects to identify whether an object has entered or left its sensing range.

[0040] The audible and visual alarm device is installed on the bed frame body 100 and is communicatively connected to each of the pressure sensors 410 and each of the infrared monitors 420, so as to trigger the audible and visual alarm device through pressure signals and infrared detection signals.

[0041] Specifically, when some pressure sensors 410 detect pressure values, it indicates that the patient is lying normally in bed, and the audible and visual alarm device will not be triggered. However, when the pressure collected by all pressure sensors 410 drops sharply to 0, it indicates that the patient has completely gotten out of bed, and the pressure signal will be transmitted to the audible and visual alarm device to trigger it.

[0042] Alternatively, when the signal detected by the infrared monitor 420 remains weak, it indicates that the patient is lying normally in bed, and the audible and visual alarm device will not be triggered. However, when the infrared detection signal generated by the infrared monitor 420 changes from a weak first infrared detection signal to an extremely strong second infrared detection signal, and then disappears to 0, it indicates that the patient has completely gotten out of bed, and the infrared detection signal will be transmitted to the audible and visual alarm device to trigger the alarm.

[0043] In a specific embodiment of this utility model, the medical care system refers to the medical care station and the mobile phones of medical staff.

[0044] In addition, the audible and visual alarm device is also connected to the medical station and the mobile phones of medical staff to transmit alarm signals to the medical station and mobile phones, so that medical staff can respond in a timely manner. The communication connection method is Bluetooth or WiFi (wireless network) technology.

[0045] In a specific embodiment of this utility model, the audible and visual alarm device adopts the TGSG-06 series audible and visual alarm device.

[0046] Among them, such as Figure 2 As shown, the smart ankle bracelet is worn on the patient's feet and is communicatively connected to a smart sensor 430 at the bottom of the bed frame body 100 to sense the distance between the patient and the bed rails. The smart sensor 430 is communicatively connected to the audible and visual alarm device. When the distance between the patient and the bed rails exceeds a preset safety value, the smart sensor 430 will send the detected distance signal to the audible and visual alarm device to trigger it.

[0047] Specifically, when the patient wears the smart ankle bracelet, the bracelet automatically establishes a communication connection with the smart sensor 430 and senses the distance between the patient and the bed rails. When the distance between the patient and the bed rails exceeds 1.5 meters, the smart sensor 430 immediately triggers an audible and visual alarm.

[0048] In addition, the alarm information triggered by the sound and light alarm device triggered by the smart sensor 430 will also be transmitted to the medical station and mobile phone so that medical staff can detect it in time. The alarm information triggered by the sound and light alarm device triggered by the smart sensor 430 also carries the distance of the patient from the bed and the patient's own location information. Therefore, the patient who has left the bed can also be located and tracked through the medical station and mobile phone.

[0049] In a specific embodiment of this utility model, the smart anklet is a Hitag S256 model smart anklet.

[0050] Furthermore, cameras can be installed around the anti-fall bed and anti-lost alarm bed rails, and connected to the intelligent monitoring system and medical care system to provide more comprehensive monitoring and recording.

[0051] Therefore, this fall-prevention and anti-lost alarm bed rails are equipped with multiple triggers that activate the audible and visual alarm devices, including pressure sensors, infrared monitors, and smart ankle bracelets, to comprehensively monitor whether the patient has left the bed. Once any of the triggers activates the alarm signal, the medical station can be remotely notified, and information can be sent to the medical staff's mobile phones to effectively ensure the patient's safety and track the patient's location information.

[0052] The hardware devices involved in this utility model include pressure sensors, infrared monitors, sound and light alarm devices, smart ankle bracelets, smart sensors, and medical care systems. The software installed in the above-mentioned hardware devices and the software processes and algorithm steps used are all based on existing software and algorithms, and are not the inventive point of this utility model. This utility model is mainly for protecting the combination of various hardware devices.

[0053] In summary, the bed rail provided by this utility model, which provides an anti-fall-out and anti-wandering alarm system, forms a complete anti-fall-out and anti-wandering alarm solution through pressure sensors, infrared monitors, intelligent sensors, and audible and visual alarm devices installed on the bed rail. This solution not only improves patient safety but also reduces the burden on nursing staff (especially during nighttime work hours) and improves hospital management efficiency.
