Description

A watch strap and a wristband-type blood pressure measuring watch using the watch strap Technical Field

[0001] This utility model relates to the medical field, specifically to a watch strap and a wristband-type blood pressure measuring watch using the watch strap. Background Technology

[0002] In recent years, wearable blood pressure monitoring devices have gradually become a research hotspot in the field of health management due to their non-invasiveness and portability. By integrating a micro-inflatable structure on the inside of the strap, a micro-pump is used to periodically inflate and deflate the inflatable balloon to collect the pressure waveform of the radial artery wall, and the systolic and diastolic blood pressure values ​​are calculated based on the oscillometric method.

[0003] However, the measurement accuracy of airbag-type blood pressure watches is highly dependent on the performance of the strap structure, specifically:

[0004] During the airbag pressurization process, the traditional watch strap material will undergo non-uniform deformation due to insufficient tensile strength, which will cause the airbag pressure to be unable to be fully transmitted to the arterial wall, resulting in the attenuation of the pressure sensor signal.

[0005] In addition, conventional watch straps are typically made of breathable materials (such as rubber) to ensure airtightness, leading to high sweat retention in summer or high-temperature environments, and maintaining high humidity on the skin surface. This not only easily causes skin itching, contact dermatitis, and discomfort for the wearer, but also reduces the frictional resistance between the airbag and the skin due to the lubricating effect of sweat. This results in fluctuations in the contact pressure between the airbag and the skin when measuring blood pressure, further causing inaccurate blood pressure readings.

[0006] Therefore, there is an urgent need for a special watch strap and a blood pressure measuring watch equipped with such a strap, which can improve the shortcomings in the blood pressure detection process. Summary of the Invention

[0007] The purpose of this invention is to provide a watch strap that can effectively stabilize the watch body during blood pressure monitoring. Combined with the inflation and release of the air bladder, this reduces the risk of inaccurate readings due to strap deformation and effectively improves the accuracy of blood pressure monitoring, providing the wearer with more scientific data. Furthermore, it dissipates heat and moisture generated by the skin's metabolism, preventing diseases caused by prolonged dampness and heat on the wrist and its impact on blood pressure monitoring. Additionally, it facilitates the individual disassembly and replacement of the air bladder for maintenance or replacement.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A watch strap for a wristband-type blood pressure measuring watch, the watch strap including an air bladder and a strap body with low elasticity made using a mesh weaving process; the surface of the strap body is provided with fixing holes; the air bladder is provided with fixing blocks, and the fixing blocks are detachably connected to the fixing holes.

[0010] Compared with existing technologies, a watch strap adopting the above-mentioned technical solution and a wristband-type blood pressure measuring watch using the watch strap have the following beneficial effects:

[0011] This invention relates to a watch strap and a wristband-type blood pressure measuring watch using the same strap. The strap's weaving process utilizes a multi-directional interwoven mesh structure. Adjacent threads under stress transmit tension through mutual friction, dispersing localized stress over a larger area and preventing force concentration. Specifically, when the air bladder inflates for detection, the force is no longer concentrated on the strap portion where the air bladder is located. Combined with the overall fit of the wrist and the strap's low-elasticity material, the portion of the strap corresponding to the air bladder does not expand independently. This allows the air bladder pressure to be transmitted almost entirely to the blood vessels for detection, effectively increasing the accuracy of blood pressure measurement.

[0012] The watch strap, made with a mesh weave, has multiple ventilation holes that allow heat and moisture generated by the skin's metabolism to dissipate during wear. This avoids the lubricating effect of excessive sweat buildup, preventing interference with blood pressure monitoring and improving accuracy. It also prevents discomfort or illness caused by prolonged dampness and heat on the wrist.

[0013] Furthermore, by separating or connecting the fixing blocks and fixing holes, the airbag and the watch strap can be separated or assembled. For the structure of a blood pressure monitoring watch that has been used for a long time, the watch strap and the airbag are essentially consumable parts that have been used for a long time. With the structure that the airbag and the watch strap can be separated separately, the watch strap body and the airbag can be maintained or replaced individually.

[0014] Preferably, the belt is made of low-elasticity fibers woven in a 1:1 plain weave with warp and weft yarns. Plain weave has the highest warp and weft yarn interlacing frequency (each warp yarn and weft yarn alternately pass through), forming a dense mesh structure, which gives the fabric higher mechanical strength and resistance to deformation, while also providing a certain degree of breathability.

[0015] Preferably, the strap is made using a double-layer weaving process. The double-layer structure provides a layered load-bearing mechanism. By interweaving or independently weaving the inner and outer yarns together, a "cross-support" effect is formed. Combined with the aforementioned materials and processes, this effectively disperses the excessive force exerted by the airbag at a single point and increases the wear resistance and service life of the strap.

[0016] Preferably, the low-elasticity fiber is composed of 45% nylon 66 high-elastic yarn, 25% spandex elastomeric yarn, and 30% polyester low-elastic yarn. The fiber structure formed by combining multiple materials offers advantages in stable support, deformation resistance, and durability, making it suitable for applications requiring high structural strength and long-term stability, such as long-term wear of watch straps and blood pressure monitoring in airbags.

[0017] Preferably, a portion of the strap surface is provided with multiple retaining rings, which are evenly spaced along the length of the strap. One end of the strap is provided with a retaining buckle, which consists of a retaining part and a hook body, forming a figure-9 structure. The hook body can be engaged with different retaining rings. The connection position of the retaining buckle can be adaptively selected according to the wearer's wrist size to adjust the tightness of the strap. In this case, the requirement of a tight fit to the wrist is achieved without affecting comfort. Combined with the airbag connected to the strap, this further increases the accuracy of blood pressure detection.

[0018] Preferably, a disassembly groove is provided at the location of the fixing hole. The disassembly groove is a short strip-shaped slot and communicates with the fixing hole. The fixing block consists of a limiting block and a connecting rod. The limiting block is connected to the airbag surface through the connecting rod. The covering surface of the limiting block exceeds the diameter of the fixing hole and the width of the disassembly groove. The purpose of providing a short strip-shaped disassembly groove is to allow the fixing block to be easily disassembled in the groove direction. In other words, the operating space provided by the groove compared to the fixing hole facilitates the separation of the fixing block as a whole, which can be operated with one hand without affecting the original assembly effect.

[0019] Preferably, the belt body adopts a metal mesh belt structure woven with fine metal mesh, or a metal plate chain structure spliced ​​together from multiple block-shaped metal sheets.

[0020] In this case, the material of the watch strap is not limited to the materials mentioned above. Other materials or structural combinations are also possible. For example, a watch strap made of high-density metal wires (such as stainless steel and titanium alloy) through a precision weaving process can form a mesh structure similar to fabric, which is comfortable to wear and distributes the force evenly. This is similar to the functions of the aforementioned straps, such as stable wear, breathability, and comfort. Through the combination of multiple metal parts, the overall structure of the watch strap is stable and its tensile strength is equal to or far exceeds that of woven watch straps. It is also suitable for the blood pressure monitoring needs of airbags.

[0021] In addition, the way the strap is worn is not limited to the combination of a buckle and a ring, nor is it limited to the metal plate chain structure mentioned above. It can also be a Velcro structure that can be directly attached and easily adjusted multiple times, as follows:

[0022] Preferably, the surface of the strap away from the airbag has a hook-and-loop fastener, and the end of the strap without the airbag has multiple connecting strips, the surface of which has hook-and-loop fasteners. The end of the strap with the connecting strips can be flipped and attached to any position on the hook-and-loop fastener surface, achieving a tightening effect when the strap is worn, ensuring smooth blood pressure monitoring and comfortable wear.

[0023] In addition to the above-mentioned technical solutions, this utility model also discloses the following technical solutions:

[0024] A wristband-type blood pressure measuring watch includes a watchband as described in any of the above embodiments; it also includes a monitoring head, wherein the air bladder is located on the inner surface of the watchband.

[0025] Compared with existing technologies, a wristband-style blood pressure measuring watch that adopts the above-mentioned technical solution has the following beneficial effects:

[0026] The airbag and the monitoring head are fixed assembly ends. The distance between the assembly end and the fixing hole (the assembly point between the strap and the airbag) is the entire length of the airbag. This means that when the airbag is assembled on the inside of the strap, it simultaneously meets the requirements for airbag assembly and normal use. Furthermore, considering the overall fit of the wrist, the strap's almost fixed structure allows the airbag to exert its expansion and contraction force as much as possible towards the wrist skin during blood pressure measurement, effectively increasing the accuracy of the wristband-type blood pressure measuring watch.

[0038] In this embodiment, the belt body 2 is made of low elasticity fiber using a 1:1 plain weave of warp and weft yarns, and the belt body 2 is prepared using a double-layer weaving process.

[0039] The low-elasticity fiber is composed of 45% nylon 66 high-elastic yarn, 25% spandex elastomeric yarn, and 30% polyester low-elastic yarn.

[0040] Regarding the wearing method of the strap 2, a plurality of fixing rings 5 ​​are provided on part of the surface of the strap 2.

The hook 61 can be respectively locked into different fixing rings 5.

[0041] To facilitate the installation and removal of the airbag 1, a disassembly and assembly groove 40 is provided at the location of the fixing hole 4. The disassembly and assembly groove 40 is a short strip-shaped groove and is connected to the fixing hole 4. The fixing block 3 is divided into a limiting block 30 and a connecting rod 31 (the dotted line in Figure 3 indicates the location of the connecting rod 31). The limiting block 30 is connected to the surface of the airbag 1 through the connecting rod 31.
