Description

[Technical Field]

[0001] This invention particularly relates to a smart mattress equipped with contactless sensors that can detect various vital functions of the human body without wearing or touching it. [Background technology]

[0002] Smart mattresses currently on the market use various contact and non-contact physiological measurement technologies to measure various vital information for users in need of care and provide related services based on that information.Smart mattresses use flexible pressure sensor technology to capture body movements and use them to provide sleep quality information, fall warnings, and even provide healthy sleep support plans to support users' sleep management.

[0003] For example, heart rate can provide a wealth of information. First, it is a vital sign; while electroencephalography (EEG) analysis is commonly used to assess sleep state, it requires subjects to wear several devices, which may affect sleep quality. Heart rate information, on the other hand, can correlate with a person's sleep state, determine their level of fatigue, and even detect respiratory arrest. Modern people are increasingly health-conscious, placing greater importance on health and exercise. Heart rate can be used to assess the effectiveness of people's exercise, leading to the development of pedometers, which, combined with motion sensors, help people track their exercise status. Heart rate fluctuations also reflect the state of the sympathetic and parasympathetic nervous systems. The activity of these two systems is directly linked to emotions, and analyzing heart rate can provide a preliminary indication of emotional state.

[0004] Conventional technologies for detecting various physiological data during sleep include ultra-wideband (UWB), force-sensitive resistors, optical fiber sensors, and capacitive sensors. However, these conventional technologies are difficult to accurately determine a user's posture or are too expensive, making them unsuitable for home or outdoor use. Furthermore, common wearable devices, such as Apple's iWatch, require a tight strap around the wrist to attach the watch to the skin, otherwise noise can easily enter the device, affecting measurement results or leading to misinterpretation.

[0005] Therefore, how to measure vital information and various physiological information of the human body easily and accurately is a goal that businesses are striving to research and develop. Summary of the Invention [Problem to be solved by the invention]

[0006] The purpose of this invention is to provide a smart mattress that solves the problems of conventional technologies that require contact measurement, instantaneous monitoring, or long-term monitoring when measuring human physiological data. It adopts a "nanosecond pulse near-field radar sensing" method that can detect without contact, and not only can it sense through clothing using micro-radar detection technology, but it is also unaffected by the way it is worn or external noise, making it a physiological sensor device suitable for general use, achieving the effect of truly not wearing it, and providing more comfortable and accurate vital information collection capabilities.

[0007] Another object of the present invention is to provide a smart mattress with penetration power that can penetrate other obstacles such as clothing, bedding, protective gear, etc., and effectively reduce interference from the external environment. [Means for solving the problem]

[0009] In one embodiment, the surface structure is a waterproof, breathable fabric cover that is closed on three sides and open on one side.

[0010] In one embodiment, the bottom is a soft mat made of polyurethane (PU) material.

[0011] In one embodiment, the intermediate layer is formed from a transparent or translucent plastic material.

The surface structure (2) is closed on three sides and has an open fabric cover on one side. The inner structure (3) is embedded and completely covered in the fabric cover of the surface structure (2). The inner structure (3) further includes a bottom (4), which is a mat made of any material. PU material is used in this invention, which has good support and elasticity and can prevent excessive pressure on specific parts of the body. The device includes an intermediate layer (5) made of a transparent or translucent plastic material covering the surface of the bottom (4), a soft flexible radar antenna (51) and one or more pressure sensors (52) arranged on the surface of the intermediate layer (5) for detecting and recording the user's physiological information, such as when the user gets out of bed or their sleeping posture, and first electrical contacts (53) electrically connected to the soft flexible radar antenna (51) and the pressure sensors (52), respectively; an upper layer (6) covering the entire surface of the intermediate layer (5) to protect its structure, in this example a thin, soft cotton mat, and a second electrical contact (61) arranged in the upper layer (6) corresponding to the first electrical contacts (53) for electrical contact and conduction; and a control box (7) having a printed circuit board arranged inside as the main unit, including a power supply circuit, and providing connection to a city power source or an embedded battery as an external power source. The control box (7) is a Bluetooth module that provides wireless communication functionality and can be paired and connected to any mobile device or remote computer. A third group of electrical contacts (71) is provided on the bottom surface of the control box (7) in a convex shape, and can be fully overlapped with the second electrical contacts (61) and the first electrical contacts (53) to achieve electrical contact and conduction. A separate flap cover (72) is provided on the side of the control box (7), and a power plug (73) is provided inside, allowing connection to a streetcar via an electric wire.In addition, the control box (7) is a detachable design, which is a specific configuration including easier individual cleaning and maintenance.

[0017] See Figure 2. The soft flexible radar antenna (51) of the present invention is disposed within the intermediate layer (5) and electrically connected to the first electrical contact (53). It is a long-distance detection method that uses a 300-500MHz short-range radar to detect vital signs at a distance of 15cm. Its functions include: 1. tracking the user's oculomotor phase, light sleep, deep sleep and awake sleep status; 2. monitoring the user's heart rate and warning of fatal arrhythmias and atrial fibrillation; 3. detecting the user's breathing and detecting sleep apnea. The pressure sensors (52) are also installed in the middle layer (5) structure and are also electrically connected to the first electrical contacts (53) group, and their functions are as follows: to detect the user's bed getting-out information, and based on this, analyze and track the nocturnal walking, polyuria, and three-stage bed getting-out warnings (sitting on the bed, bed edge, getting out of bed), and send early bed getting-out warnings, effectively prevent falls, and monitor poor sleeping posture and lying state to prevent bedsores.

[0018] The first electrical contacts (53) and the corresponding second electrical contacts (61) are inner structures (3) installed on different layers, and achieve electrical conductivity by overlapping and contacting. The control box (7) is positioned over the group of second electrical contacts (61), and the bottom of the control box (7) corresponds to the third electrical contacts (71) and the second electrical contacts (61), achieving electrical conductivity with the first electrical contacts (53). The detected vital information and sensed physiological information are transmitted to the control box (7). The built-in Bluetooth module provides wireless communication function, allowing it to pair and connect with a mobile device or a remote computer device, and the information can be transmitted to the mobile device or a remote computer device for display, and the information can also be uploaded to a cloud database for storage.

[0019] As shown in Figures 3(A) and 3(B), the control box (7) of the present invention provides a power source for the normal operation of the entire smart mattress. The control box (7) is equipped with a power plug (73) on one side of the flap cover (72), which can be used to connect to the streetcar via an electric wire to supply power. The control box (7) also has a built-in battery, which is sufficient to maintain normal operation for 36 hours after the external streetcar power is cut off, eliminating the need to worry about unexpected power outages.

[0020] See the embodiments (1) and (2) shown in Figures 5 and 6. To use the smart mattress of this invention, simply place the smart mattress (1) horizontally under the pillow on the bed (corresponding to the chest area of ​​the human body), and then connect the electric wire connected to the streetcar to the control box (7). The smart mattress (1) will then start operating and can be used directly without any additional switch operations. When the user is lying on the smart mattress (1), the flexible antenna (51) will detect the user's pulse, and the time interval between the transmitted and received pulse signals will also fluctuate accordingly. This fluctuation will be transmitted to the control box (7) as vital signs such as breathing and heart rate, and then transmitted to the paired mobile device (8) or computer device (9) via Bluetooth. This vital signs will then be uploaded and stored in a cloud database for easy tracking. Furthermore, the pressure sensor (52) synchronously detects the user's bed exit information, and includes three levels of bed exit warnings (sitting on the bed, bed edge, and getting out of bed), which can prompt the user to get out of bed early, effectively preventing falls, and monitoring the user's sleeping posture and lying condition, effectively preventing bedsores. Similarly, the detected physiological information can be transmitted to a mobile device (8) or computer device (9) paired with the control box (7) via Bluetooth and displayed, or even uploaded to a cloud database and stored, which can then be used to analyze and track the user's conditions such as nocturnal walking and polyuria.

[0021] The benefits of the smart mattress designed in this invention are: 1. It reduces the burden on medical professionals for people with insomnia and elderly people living alone, eliminating the need to wear uncomfortable sensor devices for their own health. 2. It is easy to operate and install; simply place the smart mattress under the front of the chest and plug it in to begin operation. 3. Using the flexible remote sensing vital signs, it can analyze the user's sleep status, heart rate, and breathing, and determine whether they have arrhythmia (atrial fibrillation) or asymptomatic respiratory distress syndrome. 4. Physiological information detected by the pressure sensor can analyze and track whether they get out of bed, wander, or have polyuria, prevent falls, monitor sleep and sleeping habits, prevent bedsores, and record snoring and nighttime coughing. 5. It can be paired with a mobile device and store all of the user's vital signs and physiological information. 6. In the event of an unexpected power outage, the battery can provide 36 hours of power, allowing normal operation. 7. Doctors and nurses can instantly and remotely monitor patient information at home, in hospitals, nursing homes, and other locations. 8.
