Description

Technical Field

[0001] This utility model relates to a monitoring device. Background Technology

[0002] With the rapid development and widespread adoption of mobile internet and smart hardware technologies, vital sign monitoring is extending from clinical settings to home settings, exhibiting trends towards miniaturization, convenience, intelligence, and networking. Vital sign monitoring can be applied to various scenarios, such as sleep monitoring and management. Targeting bedridden individuals, it involves analyzing their vital sign data to monitor their vital activities, thereby improving sleep quality and preventing unexpected events like sleep apnea and sudden death. Current methods for monitoring vital signs primarily involve contact-based instruments (such as electroencephalogram (EEG), electrocardiogram (ECG), respiration monitors, blood pressure monitors, blood oxygen monitors, body temperature monitors, and motion monitors) to monitor the target's vital signs. However, contact-based instruments are cumbersome and can negatively impact comfort.

[0003] As a result, non-contact sleep monitoring devices have emerged on the market. These devices can penetrate clothing and bedding to directly capture physiological signals, eliminating the discomfort associated with traditional monitoring methods. However, existing non-contact sleep monitoring devices have a limited monitoring range, and users changing sleeping positions during sleep can easily cause inaccurate data. Utility Model Content

[0034] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0035] refer to Figures 1-7 This embodiment provides a monitoring device, including: a support layer 1, a communication module 2, and a non-contact vital sign monitoring module 3. The non-contact vital sign monitoring module 3 captures displacement changes caused by heartbeats and chest cavity fluctuations, and calculates parameters such as heart rate and respiration by extracting waveform features of the original heartbeat and respiratory waves. There are two non-contact vital sign monitoring modules 3, and each module establishes a data transmission connection with the communication module 2. The two non-contact vital sign monitoring modules 3 can be placed symmetrically relative to the communication module 2, or they can be arranged asymmetrically, depending on the actual situation.

[0036] Since the two non-contact vital sign monitoring modules 3 are symmetrically placed relative to the communication module 2, their relative positions are identical. This eliminates monitoring errors caused by differences in their relative positions. The quality of the monitoring signals from the two non-contact vital sign monitoring modules 3 clearly indicates which module's signal should be used at the user's current location. The quality of the monitoring signal can be assessed by whether it fully reflects the heartbeat waveform characteristics, such as waveform amplitude and spikes.

[0037] In use, the aforementioned monitoring device first employs two non-contact vital sign monitoring modules 3, which alternately operate and send monitoring signals to the communication module 2. The quality of these two signals is assessed, and the monitoring signal from one of the non-contact vital sign monitoring modules 3 is selected and continuously recorded for a period of time T. During this time, the other non-contact vital sign monitoring module 3 remains dormant. This process is repeated, with the two modules alternating again to assess the signal quality. This allows for complete recording of the user's sleep signals during sleep. Even if the user moves or changes their sleeping position, the most suitable non-contact vital sign monitoring module 3 can be automatically switched to record the signal. This ensures the reliability of the sleep monitoring data, significantly increasing the monitoring range and accuracy compared to a single non-contact vital sign monitoring module 3. The aforementioned time period T can be freely set by the user or preset by the manufacturer. For example, a healthy adult sleeps an average of 8 hours per night and turns over 30 times. This means an average turning over occurs every 16 minutes, resulting in a change in sleeping position. Therefore, setting the time T to less than 16 minutes ensures the reliability of the monitoring data.

[0038] Since sleeping positions are mainly divided into three types—supine, left lateral, and right lateral—the changes in the position of the chest cavity are most significant when lying on the left or right side. Therefore, in this embodiment, the monitoring areas of the two non-contact vital sign monitoring modules 3 are arranged facing each other. The monitoring area of ​​each module 3 is a fan-shaped area with a radius of less than 2 meters and a central angle of less than 120°. The optimal monitoring area for each module 3 is a fan-shaped area with a radius of 1 meter and a central angle of 60°. This ensures that regardless of whether the user is lying on their left or right side, the user's chest cavity is located within the monitoring area of ​​one of the non-contact vital sign monitoring modules 3. The overlapping area of ​​the two non-contact vital sign monitoring modules 3 covers the user's chest cavity position when lying supine. Figure 4 As shown.

[0039] To achieve the above settings, the following specific structure is adopted in this embodiment:

[0040] The support layer 1 has a first mounting position 11 for mounting the communication module 2 along its thickness direction; the communication module 2 includes a control box upper cover 21 and a control box lower cover 22; the control box upper cover 21 and the control box lower cover 22 are assembled to form a cavity for accommodating the main control PCB 23; specifically, on the side of the control box lower cover 22 facing the control box upper cover 21, baffles 222 are provided at intervals along the circumference of the main control PCB 23, the mounting position of the main control PCB 23 is defined by the baffles 222, and mounting holes 223 are provided in the corresponding areas of the main control PCB 23 and the mounting position, so that the main control PCB 23 can be fixed to the mounting position by bolts.

[0041] To install the communication module 2 at the first installation position 11, the support layer 1 has multiple first clearance openings 12 spaced circumferentially around the outer periphery of the first installation position 11. The control box upper cover 21 and control box lower cover 22 are respectively provided with first insertion holes 211 and first insertion posts 221 corresponding to the positions of the first clearance openings 12. By inserting the first insertion post 221 through the first clearance opening 12 and into the first insertion hole 211, the communication module 2 can be installed and fixed to the support layer 1.

[0042] Similarly, the support layer 1 has a second mounting position 13 along its thickness direction for mounting the non-contact vital sign monitoring module 3. The non-contact vital sign monitoring module 3 includes a base upper cover 31 and a base lower cover 32, which together form a chamber for accommodating the non-contact sensor 33. The support layer 1 has a plurality of second clearance openings 14 spaced circumferentially around the outer periphery of the second mounting position 13. The base upper cover 31 and base lower cover 32 have second insertion holes 311 and second insertion posts 321 respectively corresponding to the positions of the second clearance openings 14. By inserting the second insertion post 321 through the second clearance opening 14 and into the second insertion hole 311, the non-contact vital sign monitoring module 3 can be installed and fixed to the support layer 1.

[0043] Two bases of the two non-contact vital sign monitoring modules 3 are respectively mounted on the support layer 1, and the two bases are respectively positioned close to the first edge 15 of the support layer 1. A mounting seat is provided on the lower cover 32 of the base, and the mounting seat includes a bottom surface 35 parallel to the lower cover 32 and a signal emitting surface 34 forming a first angle α with the bottom surface 35. A non-contact sensor 33 is mounted on the signal emitting surface 34, and the non-contact sensor 33 is equipped with a vital sign monitoring sensor, such as a radar sensor. The distance between the signal emitting surfaces 34 of the two non-contact vital sign monitoring modules 3 gradually increases in the direction away from the support layer 2, such as... Figure 2 As shown, in the direction away from the support layer 2, that is, in the direction perpendicular to the plane of the support layer 2 and extending outward, the distance between the two signal transmitting surfaces 34 gradually increases from x1 to x2. The bottom surface 35 of the mounting base includes a second edge near the first edge, and the second edge 351 is set at an angle (β-α) with the first edge 15, where α is the first angle between the bottom surface 35 or the base cover 32 and the signal transmitting surface 34, and β is the second angle between the extension direction of the signal transmitting surface 34 and the first edge 15, such that the axis of one signal transmitting surface 34 and the axis of the other signal transmitting surface 34 intersect on the side near the first edge 15. The monitoring ranges of the two non-contact vital sign monitoring modules 3 have an overlapping part, which can cover the effective range to the maximum extent. The effective range includes the position of the back of the human body corresponding to the chest cavity when the human body is lying on its side, and can receive the signal of the rise and fall of the human body's chest cavity.

[0044] Preferably, the angle of the first included angle α is 30° to 70°; the angle of the second included angle β is 45° to 75°. The interval between the two non-contact vital sign monitoring modules is 50mm to 1800mm.

[0045] The aforementioned monitoring device can be used with existing bedding at home, such as pillow 3 and mattress 4. The device can be placed under pillow 2, mattress 3, or inside pillow 2, positioned below the user's neck and chest area. This avoids direct contact between the device and the user, achieving contactless monitoring. Millimeter-wave radar can penetrate clothing and bedding to directly capture physiological signals, eliminating the discomfort associated with traditional monitoring methods. It is particularly suitable for long-term sleep monitoring and health management.

[0046] It should be noted that, in order to fully disclose this application, the operating principle of the monitoring device and the screening of monitoring signals have been described in detail in this embodiment. However, the technical problem to be solved by this application is only to provide a purely hardware monitoring device; the software algorithm is not included in the technical problem to be solved by this application.

[0047] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
