Description

Technical area

[0001] The present invention relates to a mattress, in particular to an intelligent mattress that can detect various vital functions of the human body without having to wear or touch sensors. State of the art

[0002] Smart mattresses can measure a wide range of vital information for users in need of care through a variety of contact-based and contactless physiological measurements, opening up relevant application possibilities. Smart mattresses can also be used to record upper body movements using gentle pressure sensor technology to provide information about sleep quality and warn against falling out of bed. Furthermore, a smart mattress offers healthy sleep solutions for sleep management.

[0003] For example, heart rate can reveal a variety of information, starting with indicators of lifestyle. Brainwave analysis is typically used to assess sleep status, but this requires participants to wear special devices, which can disrupt their sleep. This problem can be avoided by simply analyzing heart rhythm. Heart rate information can correspond to a person's sleep status, allowing the degree of fatigue to be assessed and even respiratory arrest to be detected. Modern people are becoming increasingly health-conscious as they place greater emphasis on health and exercise. Heart rate can also be used to evaluate the effectiveness of physical exercise and, in combination with motion sensors, has led to the development of devices such as pedometers that can record physical activity.Changes in heart rate are also linked to the sympathetic and parasympathetic nervous systems, whose activity is directly related to emotions. Thus, analyzing heart rhythm can also provide an initial assessment of emotional state.

[0004] Current technologies for collecting various physiological data during a user's sleep phase mainly include the following methods: ultra-wideband radar (UWB), force-sensitive resistor (FSR) pressure sensors, fiber optic sensors, and capacitive sensors. However, these common technologies often have difficulty accurately determining the user's posture or are expensive, limiting their use in homes or mobile settings. Furthermore, conventional wearable devices such as the Apple Watch require tightening on the wrist to ensure close contact with the skin. Furthermore, ambient noise can interfere with measurements, affecting the results and potentially leading to misdiagnosis.

[0005] For this reason, the goal of research and development in the industry is to measure information about the human organism and various physiological information in a simple and error-free way. Content of the invention

[0006] The objective of this invention is to present a smart mattress that solves the problems associated with measuring human physiological data using conventional technologies, which require contact-based measurement methods, real-time monitoring, or extended monitoring. The device uses a contactless sensor technology based on a "near-field nanosecond pulse radar" that enables micro-radar detection. This technology can measure signals even through clothing and remains unaffected by wearer restrictions or external interference. It is therefore particularly suitable for use as a physiological monitoring device for the general public, offering the advantages of wear-free and contactless use, enabling more comfortable and accurate vital data recording.

[0007] Another object of this invention is to provide a smart mattress that has the ability to penetrate clothing, bedding, protective equipment and other obstacles and effectively reduce interference from the external environment.

The control box (7) is also removable, which facilitates cleaning and individual maintenance.

[0016] As in Fig. As shown in Figure 2, in the invention, a flexible, bendable radar antenna (51) is embedded in the middle layer (5) and electrically connected to the first electrical contact (53), functioning as a non-contact detection system using a 300-500 MHz near-field radar capable of detecting vital signs at a distance of 15 cm. Its functions include: 1) tracking the user's sleep stages, such as REM, light sleep, deep sleep, and wakefulness; 2) monitoring the user's heart rate and warning of dangerous arrhythmias, such as atrial fibrillation; 3) detecting the user's breathing and issuing warnings in case of sleep apnea; and, in addition, a plurality of pressure sensor devices (52) are similarly arranged in the middle layer (5) and electrically connected to the group of first electrical contacts (53).Its features include detecting when the user leaves the bed, analyzing and tracking nighttime wandering, nocturia, a three-stage bed exit alarm (sitting on the bed, at the edge of the bed, leaving the bed), providing early warnings when leaving the bed to effectively prevent falls, and monitoring poor sleeping posture and restlessness to prevent pressure ulcers.

[0017] The aforementioned first electrical contact (53) and the corresponding second electrical contact (61) are located on different layers of the internal structure (3), which are electrically connected by overlapping contacts, wherein the control box (7) is positioned covering above the group of second electrical contacts (61), wherein the third electrical contact (71) on the underside of the control box (7) is electrically connected to the second electrical contact (61) and the first electrical contact (53) in order to send detected vital information and acquired physiological information to the control box (7), wherein the wireless communication takes place via an integrated Bluetooth module that can be coupled to mobile devices or remote computing devices,and wherein the above information may be sent to the mobile devices or remote computing devices for display or uploaded to a cloud database for storage.

[0018] As in the Fig. 3(A) and Fig. As shown in Figure 3(B), the control box (7) of the present invention provides the power source required to operate the entire smart mattress. An electrical socket (73) is provided inside the hinged cover (72), located on one side of the control box (7), for connecting the device to the mains via a power cable.

When the user lies on the smart mattress (1), the flexible radar antenna (51) registers the user's pulse rate, changing the time interval between the transmitted and returned pulses, which is then transmitted as vital information such as respiration, heart rate, etc. to the control box (7) and subsequently to a corresponding mobile device (8) or computer device (9) for display. The vital information can then be subsequently uploaded to a cloud-based database for tracking.At the same time, the pressure sensor device (52) detects when the user leaves the bed, including a three-stage bed-leaving reminder (sitting, at the edge of the bed, outside the bed) to prevent falls, as well as to monitor sleeping position or tossing, and also with a view to preventing pressure ulcers. Likewise, the acquired physiological information is transmitted via the control box (7) and Bluetooth connection to the paired mobile devices (8) or computer devices (9) and, if necessary, uploaded to the cloud, where it can be analyzed and tracked to determine whether the user is suffering from post-walking, polydipsia, or other conditions.

[0020] The improved functionality of the smart mattress presented in this invention is as follows: It reduces the burden on healthcare providers for people with insomnia and elderly people living alone, allowing them to avoid wearing uncomfortable personal health monitoring devices. It is simple and convenient to assemble and operate; the smart mattress is placed under the chest area, plugged in, and ready to use. The flexible, contactless detection system monitors vital signs such as sleep quality, heart rate, and respiration, enabling the detection of cardiac arrhythmias (such as atrial fibrillation) or sleep apnea. The pressure-sensitive physiological data provides insight into bed-leaving activity, indicates potential sleepwalking, and monitors symptoms such as nocturia to prevent falls.Additionally, sleep posture and movement are monitored, and the system helps prevent bedsores by recording snoring or nighttime coughing. It can be paired with mobile devices to record all the user's health and physiological information. In the event of an unexpected power outage, a backup battery ensures continuous operation for up to 36 hours. With this system, doctors and nurses can remotely monitor patient information in real time at home, in hospitals, or nursing homes. The removable control box facilitates cleaning and maintenance of the device. All information can be stored in a cloud database.
