Description

Technical Field

[0001] This utility model belongs to the field of monitoring watch strap technology, specifically referring to a watch strap for monitoring vital signs. Background Technology

[0002] With the increasing demand for health monitoring, wearable vital sign monitoring devices have been widely used. This is especially true for the elderly, whose physical functions gradually decline, increasing risk of chronic diseases and reduced ability to live independently. Vital sign monitoring straps, as long-lasting wearable devices, provide real-time health monitoring, emergency calls, and long-term health management, making them crucial for the health and safety of the elderly.

[0003] Existing vital sign monitoring watch bands have the following technical problems: 1. Traditional watch bands are usually made of a single material, which can cause pressure on the skin with prolonged wear. Furthermore, to ensure device fixation and protection, they often use sealed or poorly breathable materials, affecting comfort and causing skin dampness and sweating, posing a threat to skin health. 2. The watch band is used to acquire physiological data such as heart rate and blood pressure. However, some daily behaviors of the elderly can easily interfere with signal transmission. For example, when showering, the watch band may come into contact with water, and the high humidity and moisture in the bathroom may affect the performance of the shielding wire, leading to inaccurate data. In addition, dry skin in the elderly may cause unstable contact resistance between the watch band and the skin, also interfering with signal transmission. Utility Model Content

[0004] The technical problem this invention aims to solve is the issue of comfort and safety when wearing watch straps, as well as signal interference, in the prior art.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] The present invention proposes a watch strap for monitoring vital signs, including a watch strap body, wherein a movable buckle assembly is provided at the port of the watch strap body for fixing;

[0007] The watch strap body consists of an inner watch strap and an outer watch strap. The inner watch strap is made of a skin-friendly layer and has multiple tiny raised structures on its inner surface. The raised structures create air circulation between the inner and outer surfaces, improving breathability. The outer watch strap is made of an electromagnetic shielding fabric layer, and a sandwich layer is formed between the outer watch strap and the inner watch strap.

[0008] The interlayer contains a shielded cable and a vital signs monitoring unit. The shielded cable is a shielded cable with an outer shielding layer connected to an electromagnetic shielding fabric layer, forming a double electromagnetic shielding effect. One end of the shielded cable is connected to the vital signs monitoring unit, which is used to monitor the user's vital signs. The other end is connected to a data processing unit. One end of the vital signs monitoring unit extends outward to the inner wall of the inner strap.

[0009] Preferably, the shielding line is also provided with a moisture-proof coating, which is made of insulating and moisture-proof material, preferably a polyimide film coating, which can effectively prevent water vapor during bathing from corroding the shielding line and ensure the stability of signal transmission in complex environments.

[0010] Preferably, the device also includes a power module and a communication module disposed in the interlayer. Both the power module and the communication module are electrically connected to the data processing unit. The power module supplies power to the vital sign monitoring unit, the data processing unit, and the communication module, and the communication module is used to make a wireless connection with the user terminal.

[0011] Preferably, the vital signs monitoring unit includes a heart rate sensor for monitoring heart rate, a temperature sensor for monitoring body temperature, and an acceleration sensor for monitoring fall tendency.

[0012] Preferably, the skin-friendly layer is made of silicone or fluororubber, the height of the raised structure is 0.5-1.5mm, the array of multiple raised structures forms a group of breathable structures, and multiple groups of breathable structures are uniformly arranged on the inner surface of the skin-friendly layer.

[0013] Preferably, the electromagnetic shielding fabric layer is a fabric material with electromagnetic shielding function, preferably a metal fiber blended fabric with a weaving density of 100-300 metal fibers per square centimeter.

[0014] Preferably, the movable buckle assembly includes a buckle and a slot structure. The slot structure is formed at one end of the watch strap body, and the buckle is vertically connected to the other end of the watch strap body and matches the slot structure. The slot structure has a soft rubber gasket inside. The buckle has a T-shaped structure and a positioning tooth on the top. The diameter of the positioning tooth is larger than the inner diameter of the rubber gasket, thereby fixing the watch strap body.

[0015] The beneficial effects of this utility model by adopting the above structure are as follows:

[0016] 1. The skin-friendly material and raised structure of the inner strap reduce pressure on the skin. At the same time, the breathable design of the outer strap and the raised structure of the inner strap create a good breathability effect, reducing skin sweating and stuffiness, and improving wearing comfort, making it especially suitable for the elderly to wear for a long time.

[0017] 2. The outer strap is made of electromagnetic shielding fabric, which, together with the internal shielding wire, forms a double electromagnetic shielding structure. This effectively reduces the impact of external electromagnetic interference on signal transmission. The moisture-proof coating further prevents water vapor from corroding the shielding wire during bathing, ensuring that the data collected by the vital signs monitoring unit is accurate and reliable. It can also work stably even in special circumstances such as when the elderly are bathing. Attached Figure Description

[0031] Example 1

[0032] like Figure 1 and Figure 2 As shown, the present invention proposes a watch strap for monitoring vital signs, including a watch strap body 1, which is composed of an inner watch strap 11 and an outer watch strap 12. The inner watch strap 11 is made of a skin-friendly layer and has a plurality of tiny protrusions 3 on its inner surface. The protrusions 3 form air circulation with the skin to improve breathability. The outer watch strap 12 is made of an electromagnetic shielding fabric layer.

[0033] The skin-friendly layer is made of silicone or fluororubber, and the height of the raised structure 3 is 0.5-1.5mm. Multiple arrays of the raised structures 3 form a breathable structure, and multiple breathable structures are evenly arranged on the inner surface of the skin-friendly layer. The electromagnetic shielding fabric layer is a fabric material with electromagnetic shielding function, preferably a metal fiber blended fabric, with a weaving density of 100-300 metal fibers per square centimeter.

[0034] When using this structure, the inner strap 11, with its skin-friendly material and raised structure 3, reduces pressure on the skin. At the same time, the breathable design of the outer strap 12 and the raised structure of the inner strap 11 create a good breathability effect, reducing skin sweating and stuffiness, and improving wearing comfort, making it especially suitable for the elderly to wear for a long time.

[0035] Example 2

[0036] refer to Figures 1-4As shown, a sandwich layer 13 is formed between the outer watch band 12 and the inner watch band 11. A shielding cable 4 and a vital signs monitoring unit 5 are disposed within the sandwich layer 13. The shielding cable 4 is a shielded cable, and its outer shielding layer is connected to an electromagnetic shielding fabric layer, forming a double electromagnetic shielding effect. One end of the shielding cable is connected to the vital signs monitoring unit 5, which monitors the user's vital signs. The other end is connected to a data processing unit 8. One end of the vital signs monitoring unit 5 extends outward to the inner wall of the inner watch band 11. At the connection between the shielding cable 4 and the electromagnetic shielding fabric layer, conductive adhesive or welding technology is used to ensure an electrical connection.

[0037] In addition, a power module 6 and a communication module 7 are also provided in the interlayer 13. Both the power module 6 and the communication module 7 are electrically connected to the data processing unit 8. The communication module 7 is also connected to the data processing unit 8 through a shielded wire 4. The power module 6 supplies power to the vital sign monitoring unit 5, the data processing unit, and the communication module 7. The communication module 7 is used to make a wireless connection with the user terminal. The communication module 7 adopts low-power Bluetooth / WiFi wireless transmission, such as the E103-W11 module from Ebitech.

[0038] The shielding line is also provided with a moisture-proof coating 41, which is made of insulating and moisture-proof material, preferably a polyimide film coating, which can effectively prevent water vapor during bathing from corroding the shielding line and ensure the stability of signal transmission in complex environments.

[0039] As one embodiment, the vital signs monitoring unit 5 includes a heart rate sensor 51 for monitoring heart rate, a temperature sensor 52 for monitoring body temperature, and an acceleration sensor 53 for monitoring fall tendency. The heart rate sensor 51 is a MAX30102 heart rate and blood oxygen sensor, the temperature sensor 52 is a non-contact infrared temperature sensor 52MLX90632, and the acceleration sensor 53 is an attitude sensor. The data processing unit uses an STM8L152C6 chip as the main controller, responsible for receiving signals from each sensor in the vital signs monitoring unit 5 and uploading the monitoring data to the user terminal using a low-power Bluetooth communication module 7, achieving remote monitoring. Furthermore, this product primarily uses low-power chips, which can effectively extend the usage time, reduce charging frequency, and make it more convenient for elderly users.

[0040] refer to Figure 3As shown, it should be noted that the heart rate sensor 51 can be fitted with the probe on the inner side of the skin-friendly layer as needed, resulting in more accurate detection results. A collar 54 is provided on the outer side of the watch band body 1 to secure the sensor. The power module 6 can be located on the other side of the collar 54 and electrically connected to the internal modules. Its external location facilitates charging and replacement, and a waterproof structure can be added to its exterior as needed; this will not be elaborated upon further in this design.

[0041] In this embodiment, the internal shielding wire and the outer strap 12 are made of electromagnetic shielding fabric. The two work together to form a double electromagnetic shielding structure, which effectively reduces the impact of external electromagnetic interference on signal transmission. The moisture-proof coating 41 further prevents water vapor from corroding the shielding wire during bathing, ensuring that the data collected by the vital signs monitoring unit is accurate and reliable, and can work stably even in special circumstances such as when the elderly are bathing.
