AI Technical Summary
The existing watch airbag structure has the problem of unstable parameters when measuring blood pressure. It is mainly because the shape of the airbag does not match the curve of the wrist, which leads to airbag deformation and gas interference, which in turn affects the measurement accuracy.
A double-layer airbag structure including a first airbag bag and a second airbag bag is designed. The first airbag bag adopts an arc shape to fit the human wrist. The second airbag bag departs from the first pin to increase the airbag volume, provide a more uniform airbag pressure distribution, and connects the two airbag bags through the hole to ensure the balance of gas pressure.
Through the arc-shaped airbag design and double-layer structure, the accuracy and stability of blood pressure measurement are improved, the discomfort of wearing is reduced, and the uniform distribution of gas pressure inside the airbag is ensured.

Description
Technical Field
[0001] The utility model relates to the technical field of air bags, and in particular discloses an air bag structure for a pressure measuring watch. Background Art
[0002] The existing mainstream watch airbags are composed of one or two layers of airbag bag structure, and the air intake and air exhaust share a gas interface, or the two gas interfaces are on the same airbag, and the airbag is a plane instead of the same arc shape as the wrist, and is fixed to the watchband by two clips; when an airbag watch with a gas interface (that is, the air intake port, air exhaust port and sensor detection port all pass through the same gas interface) is worn on the wrist to measure blood pressure, the air intake port, air exhaust port and sensor detection port all pass through the same gas interface. There are many gas interferences. The airbag is a flat-shaped belt fixed on the watchband. When it is worn on the hand, a flat airbag is forcibly turned into an arc shape. The deformation of the airbag will cause a certain error due to the different thickness of the airbag glue. At the same time, the detected data error is large and the parameters are unstable. Another type is that the two gas interfaces are on the same airbag layer bag surface. Although the air intake gas interface and the sensor detection gas interface are separated, there is no arc-shaped wrapping part, and the detected parameters are also unstable. Utility Model Content
[0003] In order to overcome the shortcomings and deficiencies of the prior art that the detected parameters are not stable enough, the purpose of the utility model is to provide an air bag structure for a pressure measuring watch.
[0004] To achieve the above-mentioned purpose, the utility model provides an airbag structure for a pressure measuring watch, comprising a first airbag bag used in conjunction with an external pressure measuring watch; a first pin is provided on the first airbag bag, and the first pin is used to set the first airbag bag on an external watch band;
[0005] The first airbag bag is also provided with a first interface and a second interface, the first interface is used to cooperate with a sensing element on an external pressure measuring watch for detecting gas pressure, and the second interface is used for an air pump on the external pressure measuring watch to inflate and / or deflate the first airbag bag;
[0006] The first air bag is in an arc shape that fits the wrist of a human body.
[0007] Preferably, the airbag structure also includes a second airbag bag used in conjunction with the first airbag bag, and the second airbag bag is arranged on the side of the first airbag bag away from the first pin. The setting of the second airbag bag can increase the volume of the entire airbag structure, thereby providing a larger airbag space for inflation, which helps to improve the sensitivity and stability of the airbag, making blood pressure measurement more accurate and reliable. At the same time, the double-layer airbag design and making the second airbag bag away from the first pin can avoid too many pressure points at specific positions on the wrist, reducing possible discomfort when wearing. This design can distribute pressure more evenly and improve wearing comfort.
[0008] Preferably, the second airbag bag has the same curvature as the first airbag bag, so that the entire airbag structure can better adapt to the shape of the human wrist. This design can provide a closer and more fitting contact, increase the sealing between the airbag and the skin, thereby improving the accuracy and stability of the measurement. By maintaining the same curvature, the second airbag bag can provide uniform airbag pressure distribution throughout the airbag structure, helping to ensure uniform expansion and contraction of the airbag during measurement, reducing the situation of excessive or insufficient local pressure, thereby effectively improving the accuracy of the measurement results.
[0009] Preferably, a hole is provided at the connection between the first airbag bag and the second airbag bag, and the hole is used to connect the interior of the first airbag bag and the second airbag bag. By connecting the first airbag bag and the second airbag bag through the hole, the gas inside the two can be connected, which helps to maintain a balanced gas pressure inside the airbag during inflation or deflation, avoiding pressure differences caused by uneven gas distribution, thereby improving the accuracy and stability of the measurement.
[0010] Preferably, a plurality of hole bodies are provided, and the plurality of hole bodies are distributed in an array along the length direction of the first airbag bag. By distributing the plurality of hole bodies in an array along the length direction of the first airbag bag, uniform distribution and flow of gas inside the airbag can be achieved, which helps to ensure uniform distribution of gas pressure inside the airbag, avoids situations where local pressure is excessive or insufficient, and improves measurement accuracy and stability.
[0011] Preferably, the airbag structure also includes a second pin used in conjunction with the first pin, the first pin and the second pin have different shapes / sizes, and the two pins of different sizes correspond to different strength and elasticity requirements. The larger pin provides a stronger fixing force, while the smaller pin is used to provide a certain elasticity to adapt to the movement of the wrist.
[0012] Preferably, the first pin, the second pin, the first interface and the second interface are all set on the first airbag bag by hot pressing. By setting the first pin, the second pin, the first interface and the second interface on the first airbag bag by hot pressing, a more secure connection can be achieved. Hot pressing can form a strong physical connection between the connecting parts to ensure that they are firmly fixed to the airbag bag, thereby improving the stability and durability of the overall structure and effectively reducing the risk of loosening or falling off of the connecting parts. At the same time, hot pressing is usually simpler and faster, does not require additional materials or process steps, can reduce production costs and improve production efficiency, and hot pressing connection can usually make the connecting parts and the surface of the airbag bag smooth and tight without leaving additional protrusions or marks, thereby improving the overall aesthetics and texture of the product.
[0013] Preferably, the first pin and the second pin are respectively arranged at both ends of the first airbag bag in the length direction. Arranging the first pin and the second pin at both ends of the first airbag bag can simplify the installation and maintenance of the airbag system while ensuring the installation stability of the airbag.
[0014] Preferably, two extension layers are provided at one end of the first airbag bag away from the second pin, the two extension layers are connected via the first airbag bag, and the first interface and the second interface are respectively provided on the two extension layers. This design can effectively separate the air intake and detection functions. This physical separation can reduce the possibility of airflow directly impacting the sensor used with the first interface, thereby improving the measurement accuracy and stability.
[0015] Preferably, the first interface and the second interface are located on a side of the first airbag bag away from the second airbag bag, which is more convenient for users to install and allows the airbag to fit tightly against the watch.
[0016] Beneficial effects of the utility model: the arc-shaped design adopted by the first airbag bag can better fit the human wrist, provide a comfortable wearing experience, and can effectively reduce the local pressure when wearing it by imitating the natural curvature design of the human wrist, so that the user will not feel uncomfortable when wearing the pressure measuring watch for a long time. At the same time, through the design of the first airbag bag close to the wrist, it can ensure that the change of gas pressure during measurement more accurately reflects the change of blood pressure, and avoid the deformation of the airbag due to forcibly turning a flat airbag into an arc shape, which will cause a certain error due to different thickness of the airbag glue. Thereby improving the accuracy of blood pressure measurement. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.
[0028] See also Figures 1 to 6 As shown, the utility model is an airbag structure for a pressure measuring watch, comprising a first airbag bag 1 used in conjunction with an external pressure measuring watch; a first pin 5 is provided on the first airbag bag 1, and the first pin 5 is used to set the first airbag bag 1 on an external watch strap;
[0029] The first airbag bag 1 is also provided with a first interface 3 and a second interface 4. The first interface 3 is used to cooperate with a sensor on an external pressure measuring watch to detect gas pressure, and the second interface 4 is used for an air pump on the external pressure measuring watch to inflate and / or deflate the first airbag bag 1.
[0030] The first airbag 1 is in an arc shape suitable for use on a human wrist.
[0031] Specifically, the arc-shaped design adopted by the first airbag bag 1 can better fit the human wrist and provide a comfortable wearing experience. By imitating the natural curvature design of the human wrist, it can effectively reduce the local pressure when wearing, so that the user will not feel uncomfortable when wearing the pressure measuring watch for a long time. At the same time, through the design of the first airbag bag 1 close to the wrist, it can ensure that the change of gas pressure during measurement more accurately reflects the change of blood pressure, and avoid the deformation of the airbag due to forcibly turning a flat airbag into an arc shape, which will cause a certain error due to different thickness of the airbag glue. Thereby improving the accuracy of blood pressure measurement.
[0032] Specifically, through the design of the first pin 5, the first airbag bag 1 can be easily set on the external strap, making the installation process simple.
[0033] Specifically, in this embodiment, the first airbag bag 1 is in a "C" shape.
[0034] Specifically, the sensing element is a pressure sensing sensor.
[0035] Specifically, the airbag structure also includes a second airbag bag 2 used in conjunction with the first airbag bag 1. The second airbag bag 2 and the first pin 5 are respectively located on both sides of the first airbag bag 1. The provision of the second airbag bag 2 can increase the volume of the entire airbag structure, thereby providing a larger airbag space for inflation, which helps to improve the sensitivity and stability of the airbag, making blood pressure measurement more accurate and reliable. At the same time, the double-layer airbag design and making the second airbag bag 2 away from the first pin 5 can avoid excessive pressure points at specific positions on the wrist, reducing possible discomfort when wearing. This design can distribute pressure more evenly and improve wearing comfort.
[0036] Specifically, the second airbag bag 2 has the same bending curvature as the first airbag bag 1, so that the entire airbag structure can better adapt to the shape of the human wrist. This design can provide a closer and more fitting contact, increase the sealing between the airbag and the skin, thereby improving the accuracy and stability of the measurement. By maintaining the same bending curvature, the second airbag bag 2 can provide uniform airbag pressure distribution in the entire airbag structure, which helps to ensure uniform expansion and contraction of the airbag during measurement, reduces the situation of excessive or insufficient local pressure, and effectively improves the accuracy of the measurement results.
[0037] Specifically, a hole body 7 is opened at the connection between the first airbag bag 1 and the second airbag bag 2. The hole body 7 is used to connect the inside of the first airbag bag 1 and the second airbag bag 2. By connecting the first airbag bag 1 and the second airbag bag 2 through the hole body 7, the gas inside the two can be connected, which helps to maintain the gas pressure inside the airbag balanced during inflation or deflation, avoid pressure differences caused by uneven gas distribution, and thus improve the accuracy and stability of measurement.
[0038] Specifically, a plurality of hole bodies 7 are provided, and the plurality of hole bodies 7 are distributed in an array along the length direction of the first airbag bag 1. By distributing the plurality of hole bodies 7 in an array along the length direction of the first airbag bag 1, uniform distribution and flow of gas inside the airbag can be achieved, which helps to ensure uniform distribution of gas pressure inside the airbag, avoids excessive or insufficient local pressure, and improves measurement accuracy and stability.
[0039] Specifically, in this embodiment, six holes 7 are provided at equal intervals.
[0040] Specifically, the airbag structure also includes a second pin 6 used in conjunction with the first pin 5. The first pin 5 and the second pin 6 have different shapes / sizes. The two pins of different sizes correspond to different strength and elasticity requirements. The larger pin provides a stronger fixing force, while the smaller pin is used to provide a certain elasticity to adapt to the movement of the wrist.
[0041] Specifically, the pin is a prior art, including but not limited to the buckle on the sports watch, which will not be elaborated here.
[0042] Specifically, the larger pin is the second pin 6, which is located at the end away from the first interface 3 and the second interface 4 to achieve a stronger fixing force to improve the overall stability of the airbag. The first pin 5 is located at the end close to the first interface 3 and the second interface 4 and between the first interface 3, the second interface 4 and the second pin 6. The first pin 5 is used to provide a certain range of motion for the airbag to adapt to the movement of the wrist.
[0043] Specifically, the first pin 5, the second pin 6, the first interface 3 and the second interface 4 are all set on the first airbag bag 1 by hot pressing. By setting the first pin 5, the second pin 6, the first interface 3 and the second interface 4 on the first airbag bag 1 by hot pressing, a more secure connection can be achieved. Hot pressing can form a strong physical connection between the connecting components to ensure that they are firmly fixed to the airbag bag, thereby improving the stability and durability of the overall structure and effectively reducing the risk of loosening or falling off of the connecting components. At the same time, hot pressing is usually simpler and faster, does not require additional materials or process steps, can reduce production costs and improve production efficiency, and hot pressing connection can usually make the connecting components smooth and tight to the surface of the airbag bag without leaving additional protrusions or marks, thereby improving the overall aesthetics and texture of the product.
[0044] Specifically, the first pin 5 and the second pin 6 are respectively arranged at both ends of the first airbag bag 1 in the length direction. Arranging the first pin 5 and the second pin 6 at both ends of the first airbag bag 1 can simplify the installation and maintenance of the airbag system while ensuring the installation stability of the airbag.
[0045] Specifically, both the first pin 5 and the second pin 6 are spaced a certain distance from the end of the first airbag bag 1 .
[0046] Specifically, two extension layers 9 are provided at one end of the first airbag bag 1 away from the second pin 6, and the two extension layers 9 are connected via the first airbag bag 1. The first interface 3 and the second interface 4 are respectively provided on the two extension layers 9. This design can effectively separate the air intake and detection functions. This physical separation can reduce the possibility of airflow directly impacting the sensor used with the first interface 3, thereby improving the measurement accuracy and stability.
[0047] Specifically, the first interface 3 and the second interface 4 are located on a side of the first airbag bag 1 away from the second airbag bag 2, which is more convenient for users to install and allows the airbag to fit tightly to the watch.
[0048] Specifically, in other embodiments, both ends of the first airbag bag 1 and the second airbag bag 2 in the width direction are provided with an arc layer 8, and the arc layer 8 is bent in a direction away from the human wrist.
[0049] Specifically, the extension layer and the arc layer 8 are both parts of the airbag bag, and the names are only for writing needs.
[0050] It is worth noting that the watch sphygmomanometer is a medical device that uses modern electronic technology and the principle of indirect blood pressure measurement to measure blood pressure. It is mainly composed of the following components: shell, COB, air pump, deflation valve, pressure sensor, display screen, strap, etc. At present, the vast majority of home watch sphygmomanometers sold on the market use the oscillometric principle to measure blood pressure. The air pump is used to pressurize the strap to block the blood flow of the brachial artery, during which sound and small pressure pulses will be transmitted from the wrist. The instrument obtains the air pressure change through the pressure sensor, and then uses various algorithms to identify the small pulses transmitted from the wrist to the strap, and differentiates them to obtain the blood pressure value.
[0051] Air pump: The component of a blood pressure monitor used to inflate the cuff
[0052] Air release valve: A controllable air valve that can close or release the air path of the product according to the product needs.
[0053] Boost measurement technology: The sphygmomanometer uses an air pump to inflate and pressurize the strap. You use the inflation to compress the arteries. As the cuff pressure rises, the arteries go through a process of fully open-half closed-completely blocked. During the pressurization process, the air pressure changes are collected in real time, and then the blood pressure is calculated.
[0054] After being worn, the strap consists of three parts: the strap, the air bag and the cloth cover. The strap is connected to the sphygmomanometer and then worn on the wrist for measurement.
[0055] Specifically, in this embodiment, two pins are fixed on the watch strap, and two gas interfaces are installed on the bottom case of the external pressure measuring watch, and are fixed to the bottom case of the watch by screwing or buckling. The connection / installation of the airbag and the pressure measuring watch belongs to the existing technology and will not be elaborated here.
[0056] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
